Sponsor Licence Reporting Deadlines: 10 & 20 Day Rules

Sponsor Licence Reporting Deadlines: At a Glance

UK sponsor licence holders have ongoing duties to report specified changes affecting sponsored workers and the sponsoring organisation. Many worker-related changes fall within a 10-working-day reporting framework, while many organisational changes are subject to a 20-working-day period.

The deadline alone does not determine compliance. Employers also need to identify whether the event is reportable, establish the correct reporting trigger and use the appropriate Home Office procedure. Some changes require supporting documents, a licence request, a new sponsor licence application or separate immigration action for the worker.

Common reporting events include sponsored workers leaving employment, failing to start work, exceeding permitted absence thresholds or experiencing reportable changes to salary, duties or work location. Organisational reporting can arise from changes to business details, key personnel, ownership, premises or corporate structure.

Missing a required deadline can amount to a breach of sponsor duties and may expose the organisation to Home Office compliance action, including licence downgrading, suspension or revocation.

Sponsor reporting also operates alongside separate immigration and right to work obligations. A notification through the Sponsor Management System (SMS) does not authorise an otherwise impermissible employment change or replace a required immigration application or right to work check.

This guide explains the 10 and 20 working day sponsor reporting rules, the events that trigger notification requirements, how deadlines are calculated, the SMS reporting process and what employers should do where a deadline has been missed.

 

Section A: Sponsor Licence Reporting Deadlines: Key Rules

 

The Home Office sponsor guidance requires licensed employers to report specified changes affecting sponsored workers and the organisation holding the licence. The reporting framework sits alongside the sponsor’s wider duties to monitor workers, maintain accurate records and keep its licence information current.

The two principal reporting periods are:

 

• 10 working days: Generally applies to many specified changes affecting sponsored workers.
• 20 working days: Generally applies to many specified changes affecting the sponsoring organisation.

 

These are general reporting frameworks. Some events have specific triggers or procedures, and certain obligations fall outside the 10- and 20-working-day rules. A known or suspected breach of a sponsored worker’s conditions of stay, for example, should be reported as soon as reasonably practicable.

The employer should therefore identify the particular Home Office requirement before calculating the deadline or submitting a notification.

 

1. What Is the 10 Working Day Sponsor Reporting Rule?

 

The 10 working day framework applies to many reportable changes involving sponsored workers.

Common examples include:

 

• A sponsored worker failing to start employment within the applicable permitted commencement period.
• Sponsored employment or sponsorship ending earlier than expected.
• Unauthorised absence exceeding 10 consecutive working days.
• Absence without pay, or on reduced pay, exceeding 4 weeks in total in a calendar year, subject to permitted exceptions.
• Certain changes to job duties, salary or normal work location.
• Other worker changes specifically identified as reportable under the applicable sponsor guidance.

 

The reporting period does not always begin on the date the underlying issue first arises. The correct trigger depends on the Home Office rule applying to that event.

For example, unauthorised absence must be reported no later than 10 working days after the tenth consecutive working day of absence. Where a worker does not start employment within the applicable 28-day commencement period, the subsequent reporting deadline is linked to the end of that period.

An employer can therefore count 10 working days correctly and still report late if it starts from the wrong trigger.

 

2. What Is the 20 Working Day Sponsor Reporting Rule?

 

The 20 working day framework applies to many changes affecting the sponsoring organisation.

Reportable changes can include:

 

• The organisation’s registered or trading name.
• Its registered office or relevant business address.
• Branches, sites or other relevant business premises.
• Business activities or organisational circumstances.
• Ownership or corporate structure.
• Specified sponsor licence key personnel and related administrative arrangements.

 

Under the general organisational reporting rule, the sponsor will often have 20 working days from becoming aware of the relevant change. Specific provisions apply to some events, including changes involving the Authorising Officer, Key Contact and certain corporate transactions.

Mergers, acquisitions, ownership changes and business transfers can also affect the validity of the existing licence. Depending on the transaction, a new sponsor licence application may be required within a separate 20-working-day period.

 

3. Sponsor Licence Reporting Deadlines Table

 

The following table summarises common reporting events and the general deadlines employers should consider.

 

Reportable event	General deadline	Key consideration
Sponsored worker’s employment ends earlier than expected	10 working days	Identify the applicable cessation-of-sponsorship trigger.
Sponsored worker fails to start employment within the permitted commencement period	10 working days after the applicable 28-day period	Apply the detailed commencement rules and any relevant exceptions.
Unauthorised absence exceeding 10 consecutive working days	Within 10 working days after the tenth day of absence	Distinguish the absence threshold from the subsequent reporting period.
Absence without pay, or on reduced pay, exceeding 4 weeks in total in a calendar year	Generally 10 working days	Apply the permitted absence exceptions and assess whether sponsorship can continue.
Reportable change to sponsored worker’s duties	Generally 10 working days	Assess whether the change also requires a new immigration application.
Reportable salary reduction	Generally 10 working days	Assess the applicable exceptions and continued salary eligibility.
Salary increase	Generally not reportable	Specific exceptions apply, including relevant professional registration circumstances for sponsored nurses and midwives.
Reportable change to normal work location	Generally 10 working days	Consider the nature of the change and the applicable reporting exceptions.
Change to organisation’s registered name or address	Generally 20 working days	Apply the relevant organisational reporting trigger and supporting evidence requirements.
Change to sponsor licence key personnel	Specific Home Office requirements	Check the particular requirements applying to the appointment or change.
Merger, acquisition or change of ownership	Event-specific requirements, often involving 20 working days	A new sponsor licence application may be required; SMS notification alone may be insufficient.

 

Important: The table provides a general overview. The precise reporting obligation, trigger, deadline and procedure should be checked against the current Home Office sponsor guidance for the event concerned.

 

4. How Are Sponsor Reporting Deadlines Calculated?

 

The principal sponsor reporting periods are calculated in working days. Employers therefore need to apply the relevant Home Office definition and account for weekends and applicable public holidays.

The starting point is equally important. Worker-related reporting is generally linked to the trigger specified for the particular employment event, while the general organisational rule commonly runs from when the sponsor becomes aware of the change, subject to specific exceptions.

The reporting record should capture both the trigger and the calculated deadline. The date on which the issue reaches HR, the immigration team or an SMS user may not be the date from which the Home Office period runs.

 

5. How Are Sponsor Licence Changes Reported?

 

Most routine sponsor notifications are submitted through the Sponsor Management System.

Many worker-related changes are reported through Report migrant activity. Organisational changes may require a Level 1 User to use Request changes to licence details, the relevant user-management function or another Home Office procedure.

Some changes also require supporting documents, Home Office approval or a separate sponsor licence application. An SMS submission should therefore follow an assessment of the underlying event and any additional action it triggers.

Employers also need reliable SMS access. Restrictions on adding new Level 2 Users have applied since September 2026 and the Level 2 User role is scheduled to end after 8 March 2027. Reporting continuity should therefore be built around appropriate Level 1 User coverage and secure access arrangements.

 

6. What Happens if a Sponsor Misses a Reporting Deadline?

 

Missing a mandatory sponsor reporting deadline can amount to a breach of sponsor duties.

The Home Office may consider the nature and seriousness of the failure, whether it forms part of a wider pattern and the effectiveness of the sponsor’s compliance systems. Depending on the circumstances, enforcement action can include licence downgrading, suspension or revocation.

A late notification does not automatically result in revocation, and there is no general fixed financial penalty solely for submitting an SMS notification late.

Where a deadline has been missed, the employer should establish the original reporting trigger, complete any outstanding notification through the appropriate procedure and assess whether the underlying event created a separate immigration compliance problem.

 

7. How Should Employers Control Sponsor Reporting Deadlines?

 

Employers should maintain a central sponsor reporting register covering both worker and organisational changes.

For each potentially reportable event, the register should record the change, reporting trigger, applicable deadline, responsible person, submission date and supporting evidence. It should also identify any separate immigration, sponsor licence or right to work action arising from the same event.

For larger sponsors, the register should be tested against HR, payroll, attendance and corporate records. Regular reconciliation can identify changes that were implemented operationally but never referred for sponsor reporting.

The same control framework should accommodate the expanded right to work requirements in force from 1 October 2026. Sponsor reporting and right to work checking remain separate obligations, so changes to working arrangements may require assessment under both regimes.

Section B: What Is the 10 Working Day Sponsor Reporting Deadline?

 

The 10 working day sponsor reporting deadline is the general notification period applying to many changes affecting workers sponsored under the UK’s Worker and Temporary Worker immigration routes.

Under the Home Office’s Workers and Temporary Workers: Guidance for Sponsors, Part 3 – Sponsor Duties and Compliance, licensed employers must report specified changes to a sponsored worker’s circumstances within the applicable period.

These obligations allow the Home Office to maintain accurate information about sponsored employment and assess whether workers continue to be sponsored in accordance with the relevant immigration requirements.

Common reportable events include the failure of a sponsored worker to commence employment within the permitted period, the early termination of sponsorship, certain changes to employment arrangements and unauthorised absence exceeding the prescribed threshold.

However, the 10 working day rule does not apply identically to every event. Employers must identify the specific reporting requirement and the date from which the notification period begins.

In particular, the reporting trigger for a worker who fails to start employment differs from the trigger for unauthorised absence or the cessation of sponsorship.

The employer should therefore establish the nature of the event, confirm whether a notification is required and calculate the deadline using the applicable Home Office provision.

 

1. When does the 10 working day reporting period begin?

 

The reporting period generally begins by reference to the event or circumstances specified in the relevant Home Office sponsor guidance.

For many changes affecting sponsored workers, the employer must notify the Home Office within 10 working days of the relevant event occurring.

However, some reporting requirements have more specific triggers.

For example, a sponsored worker’s failure to commence employment is assessed against the applicable 28-day commencement rules, while the reporting requirement for unauthorised absence is linked to the worker being absent for more than 10 consecutive working days.

Employers should distinguish between:

 

• The event date: When the underlying employment or sponsorship change occurred.
• The reporting trigger: The date or circumstances that activate the Home Office notification requirement.
• The date of internal awareness: When HR, payroll or the immigration compliance team became aware of the change.
• The submission deadline: The final date by which the relevant notification must be completed.

 

These dates may not always be the same.

For example, where a line manager changes a sponsored worker’s normal work location but does not inform the immigration compliance team until several days later, the employer should not assume that the reporting period starts only when HR receives the information.

The sponsor should establish the correct trigger under the applicable guidance and calculate the deadline accordingly.

 

2. When must an employer report that a sponsored worker has not started work?

 

Employers must monitor whether sponsored workers commence employment within the period permitted by the relevant Home Office rules.

Under the general commencement provisions, a sponsored worker is ordinarily expected to start the sponsored role within the applicable 28-day period.

The calculation of that period depends on the relevant dates specified in the Home Office guidance, including the start date recorded on the Certificate of Sponsorship and the worker’s immigration permission.

Where the worker does not commence employment within the permitted period, the sponsor must consider whether it is required to stop sponsoring the worker and report the circumstances to the Home Office.

The October 2026 sponsor guidance provides that the relevant notification must be submitted by the end of 10 working days after the applicable 28-day period.

Employers should therefore distinguish between the initial commencement period and the subsequent reporting deadline.

A delayed start does not necessarily create an immediate reporting obligation on the originally anticipated first day of employment.

Equally, an employer should not assume that every delayed start is permissible merely because it has submitted an SMS notification.

The sponsor must assess whether the delay falls within the permitted commencement arrangements and whether any exception allows sponsorship to continue.

Employer example: A sponsored worker is due to begin employment on 5 October 2026 but does not attend because of an unexpected delay.

The employer should establish the relevant commencement date under the Home Office rules, calculate the applicable 28-day period and determine whether the worker can lawfully commence later.

If the worker fails to start within the permitted period and a report is required, the sponsor must submit the notification within the applicable 10 working day reporting period.

The employer should retain evidence explaining the delay and the action taken.

 

3. When must an employer report that a sponsored worker has left?

 

A licensed sponsor must report specified circumstances in which it stops sponsoring a worker.

This commonly includes the termination of sponsored employment before the end date originally recorded on the Certificate of Sponsorship.

Relevant circumstances may include:

 

• The worker resigning and leaving the organisation.
• The employer dismissing the worker.
• The termination of a fixed-term employment arrangement earlier than expected.
• The worker ceasing to work for the sponsoring organisation.
• Other circumstances in which the employer is required to stop sponsoring the worker.

 

The sponsor should establish the actual date on which the relevant employment or sponsorship arrangement ended.

This may differ from the date on which the worker gave notice or the date the employer decided to terminate employment.

Where the relevant reporting obligation is triggered by the cessation of sponsorship, the employer should calculate the notification period by reference to that event.

Employer example: A sponsored worker gives notice on 1 October 2026 and remains employed until 30 October 2026.

The employer should distinguish the resignation date from the date employment actually ends.

It should identify the applicable cessation-of-sponsorship reporting requirement and ensure that the notification is submitted within the prescribed period.

The sponsor should retain the resignation correspondence, employment termination records and evidence of the SMS notification. When reporting that sponsorship has ended, the sponsor must also provide the worker’s last recorded residential address, contact telephone number and any personal email addresses it holds.

 

4. What is the reporting deadline for unauthorised absence?

 

A licensed sponsor must report a sponsored worker who is absent from work without permission for more than 10 consecutive working days.

The Home Office guidance specifies that the report must be made no later than 10 working days after the tenth day of absence.

Employers must therefore distinguish between two separate periods:

 

1. The absence threshold: The worker has been absent without permission for more than 10 consecutive working days.
2. The reporting period: The sponsor must submit the required notification no later than 10 working days after the tenth day of absence.

 

The employer should not treat the initial 10-day absence threshold as though it were the complete reporting deadline.

Equally, it should not assume that every absence from work is unauthorised.

Approved annual leave, authorised sickness absence and other permitted absences must be assessed under the relevant sponsorship requirements.

The sponsor should maintain accurate attendance records and establish whether the worker’s absence meets the Home Office reporting criteria.

Where a notification is required, the information reported should include the relevant details specified by the guidance, which may include:

 

• The date the unauthorised absence began.
• The date the worker returned, where applicable.
• The reason for the absence, if known.
• Attempts made by the employer to contact the worker.
• Relevant salary deductions or employment consequences.
• Whether the organisation intends to continue sponsoring the worker.

 

Employer example: A sponsored worker fails to attend work and remains absent without permission for more than 10 consecutive working days.

The employer should establish the date on which the absence threshold was reached and calculate the subsequent notification deadline under the Home Office guidance.

It should also record its attempts to contact the worker and assess whether sponsorship can continue.

The employer should not wait indefinitely for the worker to return before addressing a reporting obligation that has already arisen. The report must also include the worker’s last recorded residential address, contact telephone number and any personal email addresses held by the sponsor.

 

5. Do employers have to report changes to a sponsored worker’s job duties?

 

Certain changes to a sponsored worker’s job duties must be reported to the Home Office within the applicable 10 working day period.

The reporting requirement depends on the nature of the change and whether the worker remains employed in accordance with the conditions of their sponsorship.

Employers should distinguish between adjustments that remain within the scope of the existing sponsored role and changes that amount to a different job for immigration purposes.

A material change in duties may require a new Certificate of Sponsorship and a change of employment immigration application rather than simply an SMS notification.

The employer should therefore assess the proposed change before implementing it wherever possible.

Relevant considerations include:

 

• Whether the worker’s occupation code remains appropriate.
• Whether the revised duties are consistent with the sponsored role.
• Whether the relevant immigration route permits the change without a new application.
• Whether the worker continues to satisfy the applicable skill and salary requirements.
• Whether an SMS notification is required.

 

Employer example: A sponsored employee is promoted into a role involving substantially different responsibilities.

The employer should assess whether the new position falls within the worker’s existing sponsorship arrangements or requires a change of employment application.

It should not assume that reporting the promotion through the SMS is sufficient to authorise the revised employment.

 

6. Do employers have to report sponsored worker salary changes?

 

Salary changes require careful consideration because the sponsor reporting rules distinguish between increases and reductions.

Under the general Home Office reporting provisions, sponsors are not required to report ordinary salary increases.

However, a specific exception applies where a sponsored pre-registration nurse or midwife completes professional registration and the relevant reporting requirement is triggered.

Employers should therefore avoid treating every pay rise as a reportable event.

Salary reductions require greater scrutiny.

Where a sponsored worker’s salary is reduced from the level stated on the Certificate of Sponsorship, the change may be reportable within 10 working days, subject to the applicable rules and exceptions.

The employer must also consider whether the revised salary continues to satisfy the immigration requirements applying to the worker.

This assessment may involve the applicable salary threshold, occupation-specific going rate, permitted salary arrangements and any relevant transitional provisions.

A timely SMS notification does not make an otherwise non-compliant salary reduction permissible.

Employer example: A sponsored Skilled Worker’s salary is reduced following a change to their working arrangements.

Before implementing the reduction, the employer should establish whether the revised salary remains compliant with the worker’s immigration route.

It should also determine whether the reduction must be reported and calculate the applicable notification deadline.

The organisation should retain evidence of the contractual change, payroll records and its immigration compliance assessment.

 

7. When must an employer report a change of work location?

 

Changes to a sponsored worker’s normal work location may trigger a Home Office reporting requirement.

Employers should consider whether the change is temporary or permanent, whether it affects the location recorded in the worker’s sponsorship arrangements and whether an exception applies.

Relevant circumstances may include:

 

• A permanent transfer to another business site.
• A change in the worker’s normal office or workplace.
• A change involving home working or hybrid working arrangements.
• Deployment to a client site or another location where the applicable sponsorship rules require notification.

 

Not every occasional business visit or temporary movement between workplaces necessarily requires an SMS report.

The employer should assess the actual working arrangements against the current Home Office guidance.

Where a reportable change occurs, the sponsor should generally submit the notification within the applicable 10 working day period.

Employer example: A sponsored worker is permanently relocated from the employer’s Manchester office to its Birmingham office.

The organisation should assess whether the relocation constitutes a reportable change to the worker’s normal work location.

Where notification is required, the employer should calculate the deadline from the applicable reporting trigger and retain evidence of the revised working arrangements.

 

8. Do employers need to report hybrid or remote working arrangements?

 

Hybrid and remote working arrangements can create sponsor reporting obligations where they change the worker’s normal work location or other relevant sponsorship circumstances.

The reporting position depends on the nature of the arrangement and the current Home Office requirements.

Employers should distinguish between a worker occasionally working from home and a material change to their normal working arrangements.

For example, a sponsored worker who moves from primarily office-based employment to a predominantly remote working arrangement may require a different reporting assessment from a worker who occasionally works from home under an existing hybrid policy.

The sponsor should also consider whether it can continue meeting its worker-monitoring and record-keeping duties under the revised arrangement.

Employers should not assume that a remote working arrangement is automatically prohibited or that every instance of home working requires notification.

The correct approach is to assess the specific circumstances and the applicable Home Office guidance.

 

9. Are changes to working hours reportable?

 

A change to a sponsored worker’s contractual working hours may have immigration implications, particularly where it affects salary, the nature of the sponsored role or the worker’s compliance with the conditions of their permission.

However, employers should not assume that every adjustment to working hours automatically requires a separate SMS notification.

The relevant assessment is whether the change falls within a reportable category under the applicable sponsor guidance and whether it affects the worker’s eligibility.

For example, a reduction in contracted hours may also reduce the worker’s salary.

The employer must then consider whether the revised salary meets the relevant immigration requirements and whether a salary change notification is required.

Where the change is part of a wider alteration to the sponsored role, additional immigration action may be necessary.

Employers should assess material changes before implementation rather than relying solely on retrospective reporting.

 

10. Can one event trigger more than one reporting obligation?

 

Yes. A single employment change can create multiple sponsor compliance requirements.

For example, an internal restructuring may involve changes to a sponsored worker’s job duties, salary and normal work location.

Each element should be assessed to determine whether it is independently reportable or requires separate immigration action.

Similarly, a corporate transaction may create both organisational reporting obligations and changes affecting individual sponsored workers.

The employer should not assume that submitting one general notification necessarily satisfies every applicable requirement.

Employer example: A sponsored worker transfers to a different office, receives a revised salary and takes on substantially different responsibilities.

The sponsor should assess the work-location change, salary arrangements and job duties separately.

It should establish whether an SMS notification is required for each relevant change and whether the revised role requires a new immigration application.

The reporting register should identify all associated actions and deadlines.

 

11. What changes do not normally require a 10 working day report?

 

Not every change affecting a sponsored worker is reportable.

Examples of circumstances that may fall outside the general notification requirements include:

 

• Ordinary salary increases, subject to the specific Home Office exceptions.
• Minor adjustments to duties that do not meet a reportable change category.
• Occasional business travel that does not constitute a reportable change of normal work location.
• Authorised absences that do not trigger a specific reporting obligation.
• Routine administrative changes that do not affect information the Home Office requires the sponsor to report.

 

These examples should not be treated as blanket exemptions.

Employers should assess the particular circumstances against the applicable sponsor guidance and retain records supporting the decision not to report where appropriate.

A change that is not reportable may still require the sponsor to update its internal records or assess the worker’s continued immigration eligibility.

 

12. How should employers manage the 10 working day reporting deadline?

 

Employers should establish procedures that identify potentially reportable worker changes as soon as they arise.

HR, payroll, recruitment teams and line managers should understand which events must be escalated to the immigration compliance function.

The employer should then determine whether the event is reportable, establish the correct trigger and calculate the submission deadline.

A central reporting register should record:

 

• The sponsored worker’s identity and relevant sponsorship details.
• The nature of the change.
• The date the underlying event occurred.
• The applicable reporting trigger.
• The calculated Home Office deadline.
• The person responsible for submitting the report.
• The date the notification was submitted.
• The supporting evidence retained.
• Any additional immigration action required.

 

Employers should aim to submit required notifications before the final permitted day wherever possible.

This provides time to resolve incomplete information, obtain necessary approvals and address technical difficulties with the SMS.

Where a report is submitted late, the organisation should establish the circumstances, address any outstanding notification and consider whether the failure indicates a wider weakness in its sponsor compliance arrangements.

Employer compliance point: The 10 working day deadline should be treated as an external legal reporting limit, not the organisation’s internal target for identifying and processing changes.

 

 

Back to top

 

Section C: What Is the 20 Working Day Sponsor Reporting Deadline?

 

The 20 working day sponsor reporting deadline applies to many changes affecting the organisation that holds a UK sponsor licence.

While the 10 working day reporting framework primarily concerns changes affecting individual sponsored workers, the 20 working day framework generally concerns the sponsoring organisation’s business details, structure, ownership and other circumstances relevant to its continued eligibility to hold a licence.

Under the Home Office’s Workers and Temporary Workers: Guidance for Sponsors, Part 3 – Sponsor Duties and Compliance, licensed sponsors must notify the Home Office of specified organisational changes within the applicable reporting period.

The general rule requires the sponsor to report relevant organisational changes within 20 working days of becoming aware of the change, subject to the exceptions and specific procedures contained in the guidance.

This distinction is important because the reporting trigger for organisational changes is not necessarily the same as the trigger for changes affecting sponsored workers.

Employers must also recognise that certain organisational developments involve more than a notification through the Sponsor Management System (SMS). Changes of ownership, mergers, acquisitions and business transfers can affect whether the existing sponsor licence remains valid and whether a new licence application is required.

The 20 working day reporting period should therefore be understood as part of the wider Home Office framework governing changes to licensed sponsoring organisations, rather than as a universal deadline that can be satisfied through a single SMS notification.

 

1. Which organisational changes must be reported within 20 working days?

 

Licensed sponsors must report specified changes to their organisation’s circumstances and the information held by the Home Office.

Common categories of potentially reportable changes include:

 

• Changes to the organisation’s registered or trading name.
• Changes to its registered office or relevant business addresses.
• Changes affecting branches, sites or other business premises.
• Changes to the nature of the organisation’s business activities.
• Changes affecting ownership or corporate structure.
• Mergers, acquisitions and certain business transfers.
• Changes affecting the organisation’s insolvency or financial circumstances where specified by the guidance.
• Changes to relevant registrations, approvals or regulatory circumstances.
• Other organisational developments expressly identified as reportable under the applicable Home Office guidance.

 

Not every administrative change automatically requires a notification, and not every organisational change is governed by precisely the same procedure.

The employer should establish whether the event is reportable, identify the applicable deadline and determine whether it can be dealt with under the existing sponsor licence.

Where the change also affects sponsored workers, separate worker-related reporting obligations may arise.

 

2. When does the 20 working day reporting period begin?

 

Under the general organisational reporting provision in the Home Office sponsor guidance, the sponsor must report the relevant change within 20 working days of becoming aware of it.

The date on which the organisation becomes aware of the change may differ from the date on which a particular HR employee, immigration administrator or SMS user receives the information.

Employers should therefore consider when the sponsoring organisation became aware of the relevant circumstances, rather than assuming that the deadline begins only when the matter reaches the individual responsible for sponsor licence administration.

The general awareness-based rule is also subject to specific exceptions.

In particular, changes involving the Authorising Officer or Key Contact must be considered under the relevant Home Office provisions rather than automatically applying the same awareness-based trigger.

Corporate changes may also involve separate deadlines linked to the transaction or transfer itself. Relevant C4 mergers, takeovers, direct ownership changes and similar corporate changes must be reported within 20 working days of the change taking place, and separate new sponsor licence application requirements may also arise.

Employer example: A company changes its registered business address, but the immigration compliance team is not informed until two weeks later.

The sponsor should establish when the organisation became aware of the relevant change and calculate the reporting deadline in accordance with the applicable Home Office provision.

It should not assume that the 20 working day period starts only when the Level 1 User receives the information.

 

3. Do employers have to report a change of company name?

 

A change to the sponsoring organisation’s registered or trading name may require notification to the Home Office.

This can arise where an employer undertakes a rebranding exercise, changes its registered company name or alters other business details relevant to its sponsor licence.

The employer should establish the nature of the change and whether it affects the legal identity of the sponsoring organisation.

A straightforward change of name by the same legal entity may be treated differently from a transaction in which the employing business becomes a different legal entity.

Where the change is reportable under the organisational reporting provisions, the sponsor should generally submit the required notification within 20 working days of becoming aware of the change, subject to the applicable guidance.

The Home Office may require supporting evidence demonstrating the change, such as relevant company registration documents.

Employer example: A licensed sponsor changes its registered company name following a rebranding exercise.

The employer should identify the appropriate SMS request, provide the information and supporting documents required by the Home Office and retain evidence of the submission.

It should also consider whether the change affects the information held on existing sponsorship records or requires additional administrative action.

 

4. What is the reporting deadline for a change of business address?

 

A change to the sponsoring organisation’s registered office, trading address or other relevant business premises may require a Home Office notification.

Under the general organisational reporting framework, a reportable address change will commonly be subject to the 20 working day deadline.

The employer should identify the relevant reporting trigger and follow the applicable SMS procedure.

Where the change affects the organisation’s operating premises, the Home Office may require further information or supporting evidence.

Employers should also consider whether a business relocation creates separate reporting obligations affecting sponsored workers.

For example, relocating the organisation’s registered office does not necessarily mean that every sponsored worker has changed their normal work location.

Conversely, relocating an operational site may involve both an organisational change and reportable changes to the working arrangements of individual sponsored employees.

Employer example: A sponsor moves its head office from Liverpool to Manchester and transfers several sponsored workers to the new premises.

The organisation should assess the reportable business address change under the organisational reporting rules.

It should separately consider whether the sponsored workers’ normal work locations have changed and whether notifications are required within the applicable worker reporting period.

The sponsor should not assume that reporting the new head office address automatically satisfies every worker-related notification requirement.

 

5. Must employers report changes to branches or business premises?

 

Changes affecting the branches, sites or premises through which a sponsoring organisation operates may create Home Office reporting obligations.

Relevant circumstances can include opening a new branch, closing an existing site or making other changes to the locations associated with the sponsor licence.

The reporting requirements depend on the nature of the change and the organisation’s sponsorship arrangements.

For example, a sponsor operating multiple branches may need to ensure that its licence information accurately reflects the business premises relevant to its sponsorship activities.

The employer should also consider whether the change affects where sponsored workers undertake their duties.

Where a branch closure results in sponsored workers being relocated, the organisation may need to address both the organisational change and the workers’ revised employment arrangements.

Employers should maintain accurate records of their business premises and establish a process for referring proposed site changes to the immigration compliance function before implementation.

 

6. Do changes to business activities need to be reported?

 

Certain changes to the nature of the sponsoring organisation’s business activities may require notification to the Home Office.

These may include material developments affecting the type of business undertaken, the organisation’s operating model or other circumstances relevant to its sponsor licence.

The employer should consider whether the change affects the information originally provided to the Home Office or its continued eligibility to sponsor workers.

For example, an organisation that substantially changes its business operations may need to assess whether its existing sponsorship arrangements remain appropriate.

Changes in business activities can also affect the duties performed by sponsored workers.

Where employees are transferred into materially different roles, the sponsor should consider whether separate worker-related reporting obligations or immigration applications arise.

The employer should not assume that a change to the nature of its business is adequately addressed by updating internal company records alone.

 

7. What happens when a sponsor licence Authorising Officer changes?

 

The Authorising Officer is the senior individual designated by the sponsoring organisation as responsible for its compliance with sponsor duties.

A change to the Authorising Officer must be managed under the specific Home Office rules governing sponsor licence key personnel.

Employers should not automatically apply the general awareness-based organisational reporting trigger to the replacement of the Authorising Officer.

The relevant guidance contains specific provisions governing changes to this appointment and the procedure for requesting or recording the replacement.

The organisation should ensure that the proposed replacement satisfies the applicable eligibility and suitability requirements.

It should also maintain appropriate oversight of sponsorship compliance while the change is being processed.

Employer example: The organisation’s Authorising Officer resigns from their senior management position.

The sponsor should promptly establish the requirements for appointing a replacement, identify the appropriate SMS procedure and ensure that the organisation continues to meet its key personnel obligations.

It should not assume that the departure can be treated as an ordinary administrative change without considering the specific Home Office requirements.

 

8. Must changes to the Key Contact or SMS users be reported?

 

Changes affecting the sponsor licence Key Contact and authorised SMS users must be managed in accordance with the relevant Home Office requirements.

The Key Contact is the designated point of contact between the sponsoring organisation and the Home Office in relation to its licence.

Changes to this appointment are subject to specific provisions and should not automatically be assessed using the general organisational awareness-based reporting rule.

Changes to Level 1 Users must also be managed through the appropriate SMS procedures.

Employers should ensure that the individuals responsible for sponsor licence administration remain eligible, appropriately authorised and able to access the functions required to meet reporting obligations.

The Home Office introduced restrictions on adding new Level 2 Users from 9 September 2026, with the role scheduled to be removed entirely after 8 March 2027.

Employers should therefore focus their continuity arrangements on appropriate Level 1 User access rather than relying on the future appointment of additional Level 2 Users.

Where an authorised user leaves the organisation, the sponsor should address the change promptly and ensure that outstanding reporting obligations can still be completed.

 

9. Do mergers and acquisitions have to be reported within 20 working days?

 

Mergers and acquisitions can create significant sponsor licence obligations because a licence is granted to a particular sponsoring organisation and cannot simply be assumed to transfer to another legal entity.

Where a business is acquired, merged or reorganised, the employer must assess whether the transaction changes the legal entity responsible for sponsorship.

Relevant C4 mergers, takeovers, direct ownership changes and similar corporate changes must be reported within 20 working days of the change taking place. In specified circumstances, a new sponsor licence application must also be made within the applicable 20-working-day period.

The relevant deadline and procedure depend on the nature of the transaction, the identity of the organisations involved and the arrangements affecting sponsored workers.

Employers should distinguish between:

 

• A change in the ownership of an existing sponsoring legal entity.
• A transfer of business activities between separate legal entities.
• A merger resulting in the creation of a new organisation.
• An acquisition involving the transfer of sponsored employees.
• An internal group restructuring that changes the entity responsible for sponsorship.

 

These transactions may have different sponsorship consequences.

Submitting an organisational change notification through the SMS does not necessarily satisfy a requirement for a new sponsor licence application.

Employer example: Company A acquires Company B, which employs several sponsored Skilled Workers.

The acquiring organisation should establish whether Company B remains the same sponsoring legal entity or whether the transaction involves a transfer of sponsored workers to another organisation.

Where a new sponsor licence application is required, the employer must comply with the relevant Home Office procedure and deadline.

The transaction should be assessed before completion wherever possible, rather than leaving the sponsorship implications to be resolved afterwards.

 

10. What are the sponsor reporting requirements for TUPE transfers?

 

Business transfers involving the Transfer of Undertakings (Protection of Employment) Regulations 2006, commonly known as TUPE, can create additional sponsor licence requirements.

Although TUPE may protect employees’ contractual rights when their employment transfers between organisations, it does not automatically transfer a sponsor licence or remove the Home Office’s sponsorship requirements.

Where sponsored workers transfer to another employing entity, the organisations involved must establish how the transfer affects the existing sponsorship arrangements.

Depending on the circumstances, the transferring and receiving organisations may have separate reporting obligations.

The receiving employer may also need to hold or obtain the appropriate sponsor licence.

Where a new sponsor licence application is required following a qualifying transfer, the applicable Home Office provisions may impose a 20 working day application deadline. This is separate from the C4 requirement to report the relevant corporate change within 20 working days of the change taking place.

Employers should assess:

 

• Which legal entity currently sponsors the affected workers.
• Which entity will employ the workers after the transfer.
• Whether the receiving organisation already holds the necessary sponsor licence.
• Whether a new sponsor licence application is required.
• What notifications must be submitted by the transferring and receiving sponsors.
• Whether the workers’ existing immigration permission can continue under the applicable transfer provisions.

 

Employer example: A business transfers part of its operations to another company under TUPE, including employees sponsored under the Skilled Worker route.

The organisations should assess the sponsorship implications before the transfer takes effect.

They should establish the relevant notification and licence application requirements, allocate responsibility for compliance and retain evidence of the action taken.

The employer should not assume that compliance with TUPE employment law requirements automatically satisfies the immigration sponsorship rules.

 

11. Do internal group restructurings trigger sponsor reporting duties?

 

Internal corporate restructurings may trigger sponsor reporting obligations where they affect the legal entity holding the sponsor licence or other information relevant to the Home Office.

Examples include transferring employees between group companies, reorganising subsidiaries or changing the ownership structure of a sponsoring entity.

The fact that the organisations form part of the same corporate group does not necessarily mean that they can use the same sponsor licence interchangeably.

Employers should establish whether the restructuring changes the entity responsible for employing and sponsoring the workers.

Where the existing sponsoring entity remains unchanged, the reporting implications may differ from those arising where workers transfer to another legal entity.

Some restructurings may require only specified notifications, while others may trigger new sponsor licence application requirements.

The employer should assess the transaction structure, the identity of the employing entities and the applicable Home Office corporate change provisions before implementing the restructuring.

 

12. Must insolvency or administration be reported to the Home Office?

 

Changes affecting the sponsoring organisation’s insolvency or financial circumstances may create reporting obligations and wider sponsor licence implications.

Relevant circumstances can include entering administration, liquidation or other formal insolvency processes.

The employer should establish the specific Home Office requirements applying to the event and whether the organisation remains eligible to hold its sponsor licence.

The consequences may depend on the nature of the insolvency procedure and whether the sponsoring business continues operating.

Insolvency may also affect sponsored workers through redundancies, changes to employment arrangements or transfers to another organisation.

These developments can create separate worker-related reporting obligations.

Employer example: A sponsoring company enters administration and subsequently makes several sponsored workers redundant.

The organisation should assess the reporting requirements arising from the insolvency event and separately consider the cessation-of-sponsorship notifications required for affected workers.

Where the business or employees are transferred to another legal entity, the relevant corporate change and licence application rules must also be considered.

 

13. Do changes to regulatory approvals or registrations need to be reported?

 

Some sponsoring organisations operate in regulated sectors or rely on particular registrations, authorisations or approvals relevant to their sponsor licence eligibility.

Where a relevant approval is withdrawn, suspended, expires or materially changes, the employer may be required to notify the Home Office.

The reporting requirement depends on the nature of the approval, the organisation’s activities and the applicable sponsor guidance.

Examples may arise in sectors where employers must hold regulatory authorisation to carry out particular activities.

A loss of the necessary approval may create a wider suitability or eligibility issue beyond the reporting obligation itself.

The employer should therefore assess whether the development affects its continued ability to sponsor workers.

Where a notification is required, the sponsor should follow the applicable reporting procedure and provide any supporting information requested by the Home Office.

 

14. Can one organisational change trigger both 10 and 20 working day deadlines?

 

Yes. A single business event can trigger separate reporting obligations affecting the sponsoring organisation and individual sponsored workers.

For example, a business relocation may require an organisational address notification within the applicable 20 working day period.

If sponsored workers are also moved to a different normal work location, separate worker-related notifications may be required within the applicable 10 working day period.

Similarly, a corporate restructuring may require an organisational notification or new sponsor licence application while also affecting the employment circumstances of individual sponsored workers.

Employers should assess each obligation independently.

The reporting periods may begin on different dates, and the submission of one notification does not necessarily satisfy the other.

Employer example: A company restructures its operations, closes one business site and transfers several sponsored workers to another location.

The sponsor should assess:

 

1. Whether the organisational restructuring is reportable.
2. Whether the closure of the business site requires a separate notification.
3. Whether the workers’ normal work locations have changed.
4. Whether their duties, salaries or other employment arrangements have also changed.
5. Whether any new sponsor licence or immigration applications are required.

 

The organisation should record each applicable reporting trigger and deadline rather than relying on a single general notification.

 

15. How are organisational changes reported through the SMS?

 

Many organisational changes are managed through the Sponsor Management System by an appropriately authorised Level 1 User.

Depending on the change, the relevant functions may include Request changes to licence details and the facilities for managing authorised SMS users.

The employer should identify the correct procedure before submitting the notification.

Some requests may require supporting documents or further consideration by the Home Office. Where an organisational SMS request requires a submission sheet, declaration or supporting documents, these must be sent to the Home Office within 5 working days. Any further documents requested must also be provided within 5 working days.

In limited circumstances, the relevant procedure may involve a sponsor change of circumstances form or another prescribed process.

Employers should distinguish between:

 

• Submitting a report of a change.
• Requesting an amendment to the sponsor licence details.
• Providing supporting evidence.
• Obtaining Home Office approval where required.
• Submitting a new sponsor licence application.

 

These are not necessarily interchangeable actions.

Where the Home Office must consider or approve a request, the sponsor should monitor its progress and respond to any additional requirements.

The organisation should retain evidence of the original change, the notification or application submitted and any subsequent Home Office correspondence.

 

16. What records should employers retain for organisational changes?

 

Employers should retain accurate records demonstrating the nature of reportable organisational changes and the action taken to comply with the relevant Home Office requirements.

The appropriate evidence depends on the type of change.

For example, a change of registered company name may be supported by company registration documents, while a corporate acquisition may require transaction documents establishing the ownership and legal structure of the organisations involved.

Relevant records may include:

 

• Company registration documents.
• Board resolutions and relevant corporate approvals.
• Business address and premises records.
• Documents relating to mergers, acquisitions or business transfers.
• Evidence of changes to relevant regulatory approvals.
• Records concerning the appointment or departure of sponsor licence key personnel.
• Copies or records of SMS notifications and change requests.
• Supporting documents submitted to the Home Office.
• Home Office correspondence and decisions.
• Internal records of reporting triggers, deadlines and completion dates.

 

The employer should retain records in accordance with the applicable sponsor guidance and relevant data protection requirements.

A central reporting register can help connect the underlying corporate event with the corresponding Home Office notification and any additional compliance action.

 

17. How should employers manage the 20 working day reporting deadline?

 

Employers should ensure that material organisational changes are referred for immigration compliance assessment at an early stage.

Responsibility should not rest solely with HR or the individual administering the SMS.

Company secretarial teams, finance departments, senior management and those responsible for mergers, acquisitions or restructuring should understand that their decisions may affect the sponsor licence.

For planned changes, the employer should assess the sponsorship implications before implementation wherever possible.

The reporting process should establish:

 

1. What organisational change has occurred or is proposed.
2. Whether the change is reportable under the Home Office guidance.
3. Whether the general 20 working day rule or a specific requirement applies.
4. When the relevant reporting period begins.
5. Whether the existing sponsor licence remains valid for the proposed arrangements.
6. Whether supporting documents, a separate request or a new licence application are required.
7. Who is responsible for completing the necessary action.
8. What evidence must be retained.

 

Employers should set internal reporting targets that allow sufficient time for legal assessment, document preparation and SMS submission before the relevant Home Office deadline.

Where a corporate transaction involves sponsored workers, the immigration implications should form part of the transaction’s due diligence and completion planning.

Employer compliance point: The 20 working day reporting framework is not a general grace period during which any corporate change can be implemented without considering its sponsorship consequences. Some changes affect the continued validity of the licence or trigger separate application requirements that must be addressed under the relevant Home Office rules.

Section D: Which Sponsor Licence Changes Must Be Reported to the Home Office?

 

Licensed sponsors must report specified changes affecting their sponsored workers and the sponsoring organisation. The reporting obligations are set out principally in the Home Office’s Workers and Temporary Workers: Guidance for Sponsors, Part 3 – Sponsor Duties and Compliance, alongside relevant provisions in the other sponsor guidance documents.

The reporting requirements are designed to ensure that the Home Office maintains accurate information about sponsored employment and the organisations authorised to sponsor workers in the UK.

However, not every employment or organisational change requires a notification. The employer must establish whether the particular event falls within a reportable category, identify the applicable reporting trigger and determine whether the change can be addressed through the Sponsor Management System (SMS).

Some changes require additional action, such as providing supporting documents, submitting a formal sponsor licence request or obtaining new immigration permission for the worker.

Employers should therefore distinguish between three separate questions:

 

1. Is the change reportable? Does the Home Office require the sponsor to notify it of the event?
2. When must it be reported? Which reporting deadline and trigger apply?
3. Is further action required? Does the change affect the worker’s immigration permission, the organisation’s sponsor licence or another compliance obligation?

 

These questions should be considered together, particularly where a change affects both the organisation and individual sponsored workers.

 

1. Which changes affecting sponsored workers must be reported?

 

Many of the most common sponsor reporting obligations concern changes to a sponsored worker’s employment or sponsorship arrangements.

These can arise throughout the employment relationship, from the worker’s expected commencement date through to the cessation of sponsorship.

Reportable events may include:

 

• A sponsored worker failing to commence employment within the applicable permitted period.
• The sponsor stopping sponsorship because the worker’s employment has ended.
• A sponsored worker being absent without permission for more than 10 consecutive working days.
• A sponsored worker being absent without pay, or on reduced pay, for more than 4 weeks in total in any calendar year, subject to the permitted exceptions in the sponsor guidance.
• Certain changes to the worker’s job duties or occupation.
• Reportable changes to salary or remuneration arrangements.
• Certain changes to the worker’s normal work location.
• Other changes expressly identified under the applicable sponsor guidance.

 

The general notification period for many of these events is 10 working days, but the precise reporting trigger must be established separately.

For example, the Home Office’s unauthorised absence rule requires notification no later than 10 working days after the tenth day of absence. The delayed commencement provisions instead refer to the applicable 28-day period and the subsequent reporting deadline.

Employers should not assume that every change to a sponsored worker’s employment automatically requires a report or that submitting an SMS notification makes the revised employment permissible under the Immigration Rules.

 

2. Which organisational changes must be reported?

 

Licensed sponsors must also notify the Home Office of specified changes affecting the organisation holding the sponsor licence.

These may include changes to business details, premises, ownership, structure, key personnel and other circumstances relevant to the organisation’s continued eligibility to sponsor workers.

Common categories include:

 

• Changes to the organisation’s registered or trading name.
• Changes to its registered office or relevant business address.
• Changes affecting branches or business premises.
• Changes to the nature of its business activities.
• Relevant changes to ownership or corporate structure.
• Mergers, acquisitions and certain business transfers.
• Specified insolvency events.
• Changes affecting relevant regulatory registrations or approvals.
• Changes to sponsor licence key personnel and authorised SMS users.

 

The general organisational reporting framework commonly requires notification within 20 working days of the sponsor becoming aware of the change.

However, the applicable guidance contains specific provisions and exceptions, including requirements concerning the replacement of the Authorising Officer or Key Contact.

Corporate transactions can also require a new sponsor licence application rather than merely an update to the existing licence.

The employer should therefore assess the nature of the change before selecting the reporting procedure.

 

3. Sponsor licence reporting requirements: employer reference table

 

The following table summarises common changes, the general reporting framework and the principal compliance considerations.

 

Change or event	General reporting position	Additional consideration
Sponsored worker fails to start within the permitted commencement period	Report within the applicable 10 working day period following the relevant 28-day threshold.	Assess whether sponsorship can continue under the commencement rules.
Sponsored employment or sponsorship ends	Generally report within 10 working days of the applicable cessation trigger.	Retain termination records and establish the correct final employment date.
Unauthorised absence exceeding 10 consecutive working days	Report no later than 10 working days after the tenth day of absence.	Record contact attempts, relevant absence details and the decision on continued sponsorship.
Absence without pay, or on reduced pay, exceeding 4 weeks in total in a calendar year	Generally subject to the 10 working day framework	Apply the permitted absence exceptions and assess whether sponsorship can continue.
Material change to sponsored job duties	May require a report within 10 working days.	Determine whether a change of employment immigration application is required.
Salary increase	Generally not reportable.	Specific exceptions apply, including relevant professional registration circumstances for sponsored nurses and midwives.
Reportable salary reduction	Generally subject to the 10 working day framework.	Assess continued compliance with the applicable immigration salary requirements.
Reportable change to normal work location	Generally subject to the 10 working day framework.	Consider the actual working arrangements and applicable exceptions.
Change of registered business name	Generally subject to the 20 working day organisational framework.	Establish whether the legal entity remains unchanged and whether evidence is required.
Change of registered or trading address	Generally subject to the 20 working day organisational framework.	Consider separate reporting obligations affecting sponsored workers’ locations.
Change to branches or relevant business premises	Report where required under the organisational provisions.	Assess any changes to sponsored workers’ normal work locations.
Replacement of Authorising Officer or Key Contact	Specific Home Office requirements apply.	Do not assume the general awareness-based organisational trigger applies.
Changes to authorised SMS users	Use the applicable user-management procedure.	Maintain appropriate Level 1 User access and account security.
Merger, acquisition or change of ownership	Event-specific notification and potentially new licence application requirements.	A new sponsor licence application may be required within 20 working days.
TUPE transfer involving sponsored workers	Specific corporate change and transfer provisions apply.	Assess the responsibilities of the transferring and receiving organisations.
Relevant insolvency event	Report in accordance with the applicable organisational requirements.	Assess the continued validity of sponsorship and any worker-related changes.

 

Important: The table is a practical summary, not an exhaustive statement of every reportable event. Employers should verify the precise reporting requirement, trigger, deadline and procedure against the current Home Office guidance.

 

4. What if a change affects both the employer and the sponsored worker?

 

Some business developments create separate reporting obligations under both the worker and organisational reporting frameworks.

A relocation, restructuring or business transfer may affect the organisation’s licence details while also changing the circumstances of individual sponsored workers.

For example, an employer may relocate its head office and transfer sponsored employees to the new premises.

The change to the organisation’s address may require notification under the organisational reporting rules, while the workers’ changes of normal work location may trigger separate reporting obligations.

The deadlines may be different because the relevant reporting triggers are not necessarily the same.

Employer example: A licensed sponsor closes its London office and relocates its operations to Birmingham.

The employer should assess whether the closure and relocation require changes to the organisation’s sponsor licence details.

It should separately establish which sponsored workers have experienced reportable changes to their normal work locations.

Where the restructuring also affects duties or salaries, those changes should be assessed independently.

Submitting one organisational notification does not necessarily satisfy the worker-related requirements.

 

5. When is an SMS notification insufficient?

 

An SMS notification is not always sufficient to address the immigration consequences of a change.

Some developments require a separate sponsor licence request, supporting documents, a new sponsor licence application or a change to the sponsored worker’s immigration permission.

This is particularly important in relation to:

 

• Changes to sponsored employment that require a new immigration application.
• Material changes to occupation or job duties.
• Salary changes that affect the worker’s continued eligibility.
• Corporate transactions involving changes to the sponsoring legal entity.
• Transfers of sponsored workers between organisations.
• Changes that affect the organisation’s continued suitability or eligibility to hold a sponsor licence.

 

The employer should establish the applicable requirements before implementing a planned change wherever possible.

Employer example: A sponsored Skilled Worker is promoted into a materially different role.

The employer should assess whether the new position requires a change of employment immigration application.

It should not assume that reporting the promotion through the SMS is sufficient to authorise the worker to undertake the new role.

 

6. How do the October 2026 right to work changes affect sponsor reporting?

 

The changes to the right to work framework effective from 1 October 2026 have implications for employers’ wider immigration compliance arrangements.

The revised framework extends specified right to work checking obligations beyond traditional employment to certain additional working arrangements, including relevant worker contracts, individual subcontracting arrangements and specified online matching service arrangements.

These changes do not themselves introduce a new 10 or 20 working day sponsor reporting deadline.

However, they reinforce the need for employers to assess sponsor reporting duties and right to work obligations separately when working arrangements change.

For example, a change affecting a sponsored worker’s employment or engagement may require the employer to consider:

 

• Whether the change must be reported through the SMS.
• Whether the worker remains eligible to undertake the relevant work under their immigration permission.
• Whether a right to work check or re-verification is required under the applicable rules.
• Whether the organisation must obtain or retain evidence of a check undertaken by another organisation.
• Whether the arrangement affects the sponsor’s record-keeping and worker-monitoring obligations.

 

Where a sponsored worker is employed or engaged through an arrangement involving another organisation, the sponsor should consider the applicable requirements in the Home Office’s Appendix D record-keeping guidance.

The sponsor must not assume that another organisation’s involvement automatically removes its own sponsorship responsibilities.

Equally, an employer should not assume that submitting an SMS notification satisfies a separate right to work checking obligation.

The two regimes serve different purposes. Sponsor reporting allows the Home Office to monitor changes affecting licensed sponsorship, while the right to work framework governs the checks and evidence required in relation to an individual’s entitlement to work.

Employer compliance point: Following the October 2026 changes, employers should ensure that procedures for changing sponsored workers’ employment or engagement arrangements include both a sponsor reporting assessment and a separate right to work compliance assessment where relevant.

 

7. Does completing a right to work check remove the need to submit an SMS report?

 

No. Completing a compliant right to work check does not remove an employer’s separate obligation to report specified changes affecting sponsored workers.

A right to work check establishes the individual’s entitlement to undertake the relevant work in accordance with the applicable statutory framework.

Sponsor reporting duties require the licensed employer to notify the Home Office of particular changes affecting sponsorship arrangements.

For example, an employer may complete a compliant right to work check when a sponsored worker begins employment.

If the worker subsequently experiences a reportable change to their sponsored employment, the employer may still need to submit an SMS notification.

Similarly, a sponsor may submit a timely notification concerning a change to a worker’s employment circumstances but still need to assess whether the worker has the necessary immigration permission to undertake the revised role.

The employer should therefore maintain separate but coordinated procedures for sponsor reporting and right to work compliance.

 

8. Which employment changes do not normally require an SMS report?

 

Not every change affecting a sponsored worker requires notification to the Home Office.

The reporting position depends on whether the event falls within a category identified in the applicable sponsor guidance.

Examples of changes that may not require a routine worker notification include:

 

• Ordinary salary increases, subject to the specific reporting exceptions.
• Minor changes to duties that do not meet a reportable category.
• Occasional business travel that does not constitute a reportable change of normal work location.
• Authorised absences that do not trigger a specific notification requirement.
• Routine administrative adjustments that do not affect reportable sponsorship information.

 

These examples are not blanket exemptions.

The employer should assess the actual circumstances and retain appropriate evidence supporting its decision where necessary.

A change that is not reportable may still affect the worker’s immigration eligibility, the sponsor’s record-keeping obligations or other legal requirements.

 

9. Who is responsible for identifying reportable changes?

 

The sponsoring organisation is responsible for ensuring that its reporting duties are fulfilled.

Although an authorised SMS user may submit the notification, the underlying change may arise in another department.

HR may become aware of resignations, recruitment delays or changes to employment contracts.

Payroll may implement salary changes.

Line managers may approve changes to work location, duties or attendance arrangements.

Corporate and finance teams may manage business restructurings, acquisitions or changes to company details.

The employer should establish clear internal procedures requiring these departments to escalate potentially reportable events to the appropriate immigration compliance function.

The Authorising Officer should have appropriate oversight of the organisation’s sponsorship compliance arrangements.

The Level 1 User or other appropriately authorised individual should then complete the relevant SMS action in accordance with the applicable permissions.

Following the September 2026 restrictions on adding new Level 2 Users, employers should ensure that reporting continuity arrangements are based on the current Home Office rules governing SMS access and authorised users.

 

10. How should employers decide whether a change is reportable?

 

Employers should use a consistent assessment process whenever a change affecting sponsored workers or the sponsoring organisation is identified.

The assessment should establish:

 

1. What has changed and which individuals or organisational details are affected.
2. Whether the event falls within a reportable category under the applicable Home Office guidance.
3. Whether a specific reporting exception applies.
4. Which reporting deadline governs the event.
5. When the relevant reporting period begins.
6. Whether an SMS notification, licence change request or separate application is required.
7. Whether the event creates additional immigration or right to work compliance obligations.
8. What supporting records and evidence must be retained.

 

Where the employer concludes that no report is required, it may be appropriate to document the basis of that decision, particularly for material employment or organisational changes.

This can help demonstrate that the organisation considered its sponsorship obligations rather than simply overlooking the event.

 

11. Why should employers maintain a central reporting register?

 

A central sponsor reporting register can help employers monitor changes, deadlines, submissions and outstanding compliance actions.

It should provide an auditable record linking each reportable event to the relevant Home Office requirement.

The register may include:

 

• The sponsored worker or organisational change concerned.
• The date the underlying event occurred.
• The applicable reporting trigger.
• The relevant 10 working day, 20 working day or event-specific deadline.
• The person responsible for the notification.
• The date the report or request was submitted.
• Evidence of the submission.
• Any supporting documents provided.
• Additional immigration or right to work actions required.
• The status of any outstanding Home Office request.

 

For larger sponsors, the reporting register should be supported by periodic checks against HR, payroll and organisational records.

These checks can help identify reportable changes that were not escalated and establish whether notifications were completed within the applicable deadlines.

Employer compliance point: A reliable sponsor reporting process should allow the organisation to establish not only whether a notification was submitted, but also why it was required, how the deadline was calculated and whether any separate immigration compliance obligations were addressed.

 

 

Back to top

 

Section E: When Does the Home Office Sponsor Reporting Deadline Start?

 

Identifying the correct reporting deadline is only part of complying with the Home Office’s sponsor notification requirements. Employers must also establish when the relevant reporting period begins.

A sponsor may understand that a change must be reported within 10 or 20 working days but still submit the notification late because it has calculated the period from the wrong date.

This is particularly important where an employment change develops over several stages, where the sponsoring organisation becomes aware of an event after it has occurred, or where a corporate transaction involves separate reporting and application requirements.

The Home Office sponsor guidance distinguishes between changes affecting sponsored workers and changes affecting the sponsoring organisation. Many worker-related notifications are linked to the occurrence of the relevant event, while the general organisational reporting provision refers to when the sponsor becomes aware of the change, subject to specific exceptions.

Certain events have their own reporting triggers. For example, the unauthorised absence rule refers to the tenth day of absence, while delayed commencement is governed by the applicable 28-day commencement period.

Employers should therefore identify the precise reporting trigger before calculating the submission deadline.

 

1. What is a sponsor licence reporting trigger?

 

A reporting trigger is the event, date or circumstance from which the applicable Home Office notification period is calculated.

The trigger is not necessarily the date on which the employer first discusses a proposed change, updates its HR system or asks an SMS user to submit a notification.

For reporting purposes, employers should distinguish between four dates:

 

• Event date: The date on which the relevant employment or organisational change occurs.
• Effective date: The date on which a contractual, operational or corporate change takes effect.
• Awareness date: The date on which the sponsoring organisation becomes aware of the relevant change.
• Reporting trigger: The date or event specified by the applicable Home Office guidance as starting the notification period.

 

These dates may coincide, but they should not be treated as interchangeable.

For example, a sponsored worker may give notice of resignation several weeks before their employment ends. The employer must identify the reporting obligation relating to cessation of sponsorship rather than automatically calculating the deadline from the date the resignation letter was received.

Similarly, a company may agree a proposed acquisition before the transaction completes. The relevant sponsorship obligations may depend on the legal effect of the transaction and the specific Home Office corporate change provisions.

The correct reporting trigger must therefore be established by reference to the particular event and applicable guidance.

 

2. Does the 10 working day deadline start when the change happens?

 

For many reportable changes affecting sponsored workers, the 10 working day notification period is linked to the occurrence of the relevant event.

This may include the cessation of sponsorship or certain changes to a worker’s employment circumstances.

However, employers should not assume that every worker-related reporting requirement starts on the same basis.

The Home Office guidance contains specific provisions for certain events, including failure to commence sponsored employment and unauthorised absence exceeding the prescribed threshold.

The employer should establish:

 

1. Whether the event is reportable.
2. Which Home Office provision applies.
3. What date or circumstance triggers the reporting obligation.
4. How the relevant working day period must be calculated.

 

The date on which the HR or immigration compliance team becomes aware of the event should also be recorded, but it does not automatically replace the reporting trigger specified by the guidance.

Employer example: A sponsored worker’s normal work location changes on 5 October 2026, but the immigration compliance team is informed on 12 October 2026.

Where the change is reportable, the sponsor should calculate the notification period from the trigger prescribed by the relevant worker reporting provision.

It should not automatically treat 12 October as the start of a fresh 10 working day period merely because that was when the matter reached the compliance team.

 

3. Does the 20 working day deadline start when the employer becomes aware?

 

Under the general organisational reporting provision in the Home Office sponsor guidance, relevant changes must ordinarily be reported within 20 working days of the sponsor becoming aware of them.

This differs from the event-based approach applying to many worker-related changes.

However, the awareness-based rule is not universal.

Specific exceptions apply, including provisions concerning the replacement of the Authorising Officer or Key Contact. Corporate transactions may also create separate reporting or application requirements linked to the particular transaction.

Employers should therefore establish whether the general organisational rule applies before relying on the awareness date.

It is also important to distinguish the organisation’s awareness from the personal awareness of the individual responsible for administering the sponsor licence.

A company should not assume that the reporting period begins only when its Level 1 User receives the information.

Employer example: The company secretary becomes aware of a reportable change to the organisation’s registered details on 1 October 2026 but does not inform the immigration compliance team until 14 October 2026.

Where the general organisational awareness-based rule applies, the sponsor should establish when the organisation became aware of the change.

The later internal referral should not automatically be treated as the reporting trigger.

 

4. When does the deadline start if a sponsored worker resigns?

 

A sponsored worker’s resignation can involve several relevant dates, including the date notice is given, the last day of work and the date employment or sponsorship actually ends.

The employer should establish the circumstances in which it is required to notify the Home Office that sponsorship has ceased.

Where the relevant reporting obligation concerns the cessation of sponsorship, the employer should identify the actual cessation event and calculate the deadline under the applicable guidance.

The date on which the worker gives notice should not automatically be treated as the date sponsorship ends.

However, employers must also consider whether other circumstances arise before the contractual termination date that require sponsorship to cease or trigger a separate reporting obligation.

Employer example: A sponsored worker resigns on 2 October 2026 and is due to leave on 30 October 2026.

The employer should record the resignation and monitor the worker’s remaining employment.

It should establish the relevant cessation-of-sponsorship trigger and ensure that the required notification is submitted within the prescribed period.

If the worker stops attending work without permission before the agreed termination date, a separate unauthorised absence assessment may also be necessary.

 

5. When does the reporting deadline start if a sponsored worker is dismissed?

 

Where a sponsored worker is dismissed, the employer should establish the date on which the employment and sponsorship arrangements actually cease.

This may depend on whether dismissal takes immediate effect, the worker serves notice or the employment terminates on a specified future date.

The employer should not assume that the date of an internal disciplinary decision necessarily constitutes the relevant reporting trigger.

For example, a decision to dismiss may be communicated before the worker’s contractual employment ends.

Conversely, a dismissal may take immediate effect, creating an immediate cessation-of-sponsorship event.

The sponsor should identify the applicable Home Office requirement, calculate the deadline and retain evidence of the termination arrangements.

Relevant records may include the dismissal letter, final employment date, payroll information and evidence of the SMS notification.

 

6. When does the deadline start if a sponsored worker fails to commence employment?

 

The reporting trigger for a sponsored worker who fails to start employment is governed by the Home Office’s commencement provisions.

Under the general rules, the sponsor must assess whether the worker has commenced the sponsored role within the applicable 28-day period.

The calculation of that period depends on the dates and circumstances specified in the relevant sponsor guidance.

Where the worker has not started within the permitted period and the reporting requirement applies, the Home Office guidance requires the relevant notification by the end of 10 working days after the applicable 28-day period.

The employer should therefore distinguish between:

 

1. The date from which the permitted commencement period is calculated.
2. The end of the applicable 28-day period.
3. The subsequent 10 working day reporting deadline.

 

A delayed start does not necessarily trigger an immediate reporting requirement on the originally anticipated commencement date.

However, the employer must consider whether the delay is permitted and whether sponsorship can lawfully continue.

Employer example: A sponsored worker is expected to begin employment in October 2026 but is unable to start because of a delay in their arrival.

The employer should identify the relevant commencement date under the Home Office guidance and calculate the applicable 28-day period.

If the worker does not commence within that period, the sponsor should assess whether an exception applies and submit any required notification within the subsequent reporting period.

The employer should retain evidence of the delay, communications with the worker and its assessment of the applicable sponsorship requirements.

 

7. When does the deadline start for unauthorised absence?

 

The unauthorised absence reporting requirement has a specific trigger.

Where a sponsored worker is absent from work without permission for more than 10 consecutive working days, the sponsor must report the absence no later than 10 working days after the tenth day of absence.

This means the employer must distinguish the absence threshold from the reporting period.

The first period concerns whether the worker’s unauthorised absence has reached the threshold specified by the Home Office.

The second period concerns the deadline for submitting the required notification.

The employer should not calculate the reporting deadline simply as 10 working days from the first day of absence.

Nor should it wait until the worker returns before addressing a reporting obligation that has already arisen.

Employer example: A sponsored worker is absent without permission for 12 consecutive working days.

The sponsor should identify the tenth working day of absence and calculate the notification deadline under the Home Office rule.

The report should include the information required by the guidance, such as the relevant absence dates, attempts to contact the worker and the organisation’s position on continued sponsorship.

Where the absence also leads to termination of employment, the employer should assess whether a separate cessation-of-sponsorship notification is required.

 

8. When does the deadline start for a salary change?

 

The reporting position for salary changes depends on the nature of the adjustment.

Ordinary salary increases generally do not require a sponsor notification, subject to specific exceptions in the Home Office guidance.

Salary reductions may be reportable where they fall within the relevant provisions.

Where a reduction is reportable, the employer should identify when the change to the sponsored worker’s remuneration takes effect and establish the applicable reporting trigger.

The date on which payroll processes the change may not necessarily be the same as the date on which the worker’s contractual salary changes.

Employers should also assess whether the revised salary remains compliant with the worker’s immigration route.

Employer example: An employer agrees in September 2026 that a sponsored worker’s salary will reduce with effect from 1 November 2026.

The employer should assess the immigration implications before the reduction takes effect.

Where the change is reportable, the sponsor should establish the relevant reporting trigger and calculate the deadline accordingly.

The employer should not assume that the date the agreement was signed or the date payroll processes the first revised payment necessarily determines the notification deadline.

 

9. When does the deadline start for a change of work location?

 

Where a sponsored worker’s normal work location changes in circumstances requiring notification, the employer should identify when the relevant change takes effect.

The reporting assessment should consider the actual working arrangements rather than relying solely on an internal HR record.

For example, a worker may be formally assigned to a new office from one date but begin working there on a different date.

The sponsor should establish the relevant event under the applicable Home Office guidance.

It should also determine whether the arrangement constitutes a reportable change of normal work location or falls within an exception.

Employer example: A sponsored worker is told in September that they will transfer to another office on 19 October 2026.

The employer should assess whether the proposed transfer is reportable and establish the relevant reporting trigger.

Where notification is required, it should calculate the deadline using the applicable Home Office provision and retain evidence of the revised working arrangements.

 

10. What happens when a change is agreed before it takes effect?

 

Some employment and organisational changes are planned or agreed well before their effective date.

Examples include a future salary reduction, office relocation, promotion or corporate acquisition.

The employer should distinguish between the date on which the change is proposed or agreed and the date or event that triggers the relevant Home Office requirement.

The reporting deadline should not automatically be calculated from the earliest internal discussion or approval.

However, advance planning is important because the change may require immigration permission, a sponsor licence application or Home Office approval before implementation.

Employers should therefore assess planned changes as early as possible, even where the reporting deadline has not yet arisen.

This allows sufficient time to determine whether the proposed arrangement is permitted and identify the correct notification procedure.

 

11. What if the employer discovers a reportable change late?

 

Late discovery of a reportable event can create a risk that the applicable notification deadline has already expired.

The employer should establish the original event date, the relevant reporting trigger and the date on which the organisation became aware of the circumstances.

It should then calculate whether the Home Office deadline has been missed.

Where the reporting period is linked to the occurrence of an event, a delay in referring the matter to the immigration compliance team does not automatically create a new notification period.

For organisational changes governed by the general awareness-based rule, the employer should establish when the sponsoring organisation became aware of the change rather than assuming that the deadline begins when an individual SMS user receives the information.

If the notification is overdue, the employer should address the outstanding reporting obligation promptly and retain an accurate record of the circumstances.

The organisation should also investigate why the event was not identified or escalated earlier.

Employer example: An internal audit identifies that a sponsored worker’s reportable employment change occurred several weeks earlier but was never referred to the sponsor licence team.

The employer should determine the original reporting trigger, calculate the deadline and establish whether a breach has occurred.

It should then take appropriate corrective action and review the internal procedures that allowed the change to go unreported.

 

12. Can a reporting deadline restart if the employer receives new information?

 

Employers should not assume that receiving further information about an existing reportable event automatically restarts the original notification period.

Where a reporting obligation has already arisen, the sponsor should assess the deadline by reference to the original trigger.

However, subsequent developments may create additional reporting obligations.

For example, an employer may initially identify an unauthorised absence and later decide to terminate the worker’s employment.

The absence and cessation of sponsorship may involve separate reportable events and distinct notification requirements.

Similarly, a corporate restructuring may involve a series of changes taking effect on different dates.

The sponsor should assess each event independently and avoid treating a later development as automatically extending an earlier deadline.

 

13. Can one event have several reporting triggers?

 

Yes. A single business or employment development can involve several separate reportable changes.

For example, a restructuring may result in:

 

• A change to the sponsoring organisation’s registered details.
• The closure of a business premises.
• The relocation of sponsored workers.
• Changes to individual workers’ job duties.
• Changes to salary arrangements.
• A transfer of employees to another legal entity.

 

Each relevant obligation should be assessed under the applicable Home Office provisions.

The organisation may therefore have several reporting deadlines arising from the same wider business event.

Employer example: A company acquisition completes on 1 October 2026, but the transfer of certain sponsored workers to another office takes effect on 19 October 2026.

The sponsor should assess the corporate transaction and any associated licence application requirements separately from the subsequent changes to the workers’ normal work locations.

The relevant reporting triggers and deadlines may differ.

The employer should record each requirement in its reporting register and allocate responsibility for completing the necessary action.

 

14. How should employers record reporting triggers?

 

Employers should maintain a central record identifying the reporting trigger for each potentially reportable event.

The record should distinguish between the underlying change, the date of internal awareness and the deadline calculated under the Home Office guidance.

For each event, the employer should record:

 

• The nature of the change.
• The sponsored worker or organisational details affected.
• The date the change occurred or took effect.
• The date the organisation became aware of the change, where relevant.
• The specific reporting requirement.
• The applicable reporting trigger.
• The calculated notification deadline.
• The individual responsible for submission.
• The date the notification was completed.
• Evidence supporting the calculation and submission.

 

Where the trigger is uncertain, the employer should resolve the issue promptly rather than postponing action until the final possible reporting date.

A documented assessment can help demonstrate that the sponsor has considered the applicable requirements and applied a consistent compliance process.

 

15. How can employers prevent errors in reporting trigger calculations?

 

The most effective way to prevent deadline errors is to ensure that reportable changes are identified before or immediately after they occur.

Employers should establish clear escalation procedures covering HR, payroll, recruitment, line management and corporate functions.

Internal reporting procedures should require relevant changes to be referred promptly to the immigration compliance team.

Where possible, the organisation should use standardised reporting forms or workflows that capture the dates necessary to determine the correct Home Office trigger.

Employers should also distinguish between planned changes and completed events.

For example, a proposed salary reduction should be assessed before implementation, while an unexpected resignation or unauthorised absence may require immediate review once the relevant circumstances arise.

Periodic reconciliation between HR records, payroll information and the reporting register can help identify discrepancies.

Training should explain that the deadline may begin before the immigration compliance team receives the information and that different events can be subject to different trigger rules.

Employer compliance point: The critical question is not simply when the sponsor became aware that a report was needed. It is when the reporting period began under the Home Office rule applicable to the particular event.

Section F: How Are Sponsor Licence Reporting Deadlines Calculated?

 

Sponsor licence reporting deadlines are generally calculated in working days rather than calendar days. Employers must therefore establish both the correct reporting trigger and the number of working days available to complete the relevant Home Office notification.

The distinction matters because a deadline expressed as 10 working days can extend over approximately two calendar weeks, while a 20 working day deadline can extend over approximately four calendar weeks. Weekends and relevant public holidays can affect the final submission date.

However, calculating the number of days is only one part of the exercise. An employer may count the correct number of working days but still submit a report late if it starts the calculation from the wrong event.

For many sponsored worker changes, the reporting period is linked to the relevant event occurring. For many organisational changes, the general Home Office rule requires reporting within 20 working days of the sponsor becoming aware of the change, subject to specific exceptions.

Some events also have their own reporting triggers, including unauthorised absence and failure to commence sponsored employment within the applicable period.

Employers should therefore calculate each deadline individually rather than applying a single standard formula to every sponsor notification.

 

1. What counts as a working day for sponsor reporting?

 

For the purposes of the relevant sponsor reporting requirements, employers must apply the definition of a working day contained in the applicable Home Office guidance.

The calculation generally excludes Saturdays, Sundays and relevant public holidays.

Employers should check the precise wording of the applicable guidance, including which public holidays are excluded, rather than relying solely on their organisation’s internal working calendar.

For example, a company may operate seven days a week, but that does not mean Saturdays and Sundays automatically count as working days for a Home Office reporting deadline.

Equally, an employer’s internal closure days do not necessarily extend the Home Office deadline.

The reporting period is determined by the applicable immigration guidance, not by the employer’s normal trading hours or administrative arrangements.

 

2. Does the day of the reportable event count towards the deadline?

 

Employers must distinguish the date that triggers a reporting obligation from the working days counted towards the submission deadline.

For the general worked examples below, the calculation treats the first working day after the relevant trigger as day one. This counting convention should be checked against the precise wording of the Home Office requirement governing the particular event.

Where a provision specifies a different starting point, such as a period following the tenth day of unauthorised absence or the end of a permitted commencement period, that specific provision must be applied.

The employer should not assume that every reporting deadline begins on the date a manager enters the change into an HR system or asks an SMS user to submit a report.

The correct approach is to identify the applicable Home Office reporting trigger before counting the permitted working days.

 

3. How do you calculate a 10 working day sponsor reporting deadline?

 

To calculate a general 10 working day reporting deadline, the employer should first establish the relevant reporting trigger.

It should then count the applicable working days, excluding weekends and relevant public holidays in accordance with the Home Office guidance.

The notification must be submitted within the prescribed period.

Worked example: A reportable change occurs on Monday 2 November 2026.

Assuming the applicable rule requires the employer to count from the following working day, and no relevant public holidays fall within the period, the calculation is:

 

Working day	Date
Reporting trigger	Monday 2 November 2026
Day 1	Tuesday 3 November 2026
Day 2	Wednesday 4 November 2026
Day 3	Thursday 5 November 2026
Day 4	Friday 6 November 2026
Day 5	Monday 9 November 2026
Day 6	Tuesday 10 November 2026
Day 7	Wednesday 11 November 2026
Day 8	Thursday 12 November 2026
Day 9	Friday 13 November 2026
Day 10	Monday 16 November 2026

 

On these assumptions, the tenth working day falls on Monday 16 November 2026.

The employer should nevertheless confirm that the event is subject to the general 10 working day rule and that the assumed counting convention applies.

Employer compliance point: Employers should aim to complete required SMS notifications before the final permitted working day. Waiting until the deadline creates unnecessary exposure to technical difficulties, missing information or unexpected staff absence.

 

4. How do you calculate a 20 working day sponsor reporting deadline?

 

The general 20 working day organisational reporting period must be calculated from the trigger specified in the relevant Home Office guidance.

For many organisational changes, this is when the sponsoring organisation becomes aware of the change.

However, specific exceptions apply, and some corporate transactions involve separate deadlines for reporting or submitting a new sponsor licence application.

Worked example: A sponsor becomes aware of a reportable organisational change on Monday 2 November 2026.

Assuming the general awareness-based rule applies, the first working day after the trigger is counted as day one and no relevant public holidays intervene, the calculation is:

 

Period	Working days counted
Tuesday 3 to Friday 6 November 2026	Days 1–4
Monday 9 to Friday 13 November 2026	Days 5–9
Monday 16 to Friday 20 November 2026	Days 10–14
Monday 23 to Friday 27 November 2026	Days 15–19
Monday 30 November 2026	Day 20

 

On these assumptions, the twentieth working day falls on Monday 30 November 2026.

This example should not be applied automatically to changes involving the Authorising Officer, Key Contact or corporate transactions where specific Home Office provisions govern the required action.

 

5. Do weekends count towards sponsor reporting deadlines?

 

Weekends are generally excluded when calculating reporting periods expressed in working days under the applicable Home Office guidance.

For example, where a reporting period runs across two weekends, Saturdays and Sundays would not normally be included in the count.

Employers should not confuse this with the calculation of a period expressed in calendar days.

This distinction is particularly important for delayed commencement, where the initial permitted commencement period is expressed in days, while the subsequent reporting period is expressed in working days.

Applying a working-day calculation to the initial 28-day commencement period could result in an incorrect deadline.

Employers should therefore identify whether each stage of the relevant Home Office requirement is expressed in days or working days.

 

6. Do bank holidays extend sponsor reporting deadlines?

 

Relevant public holidays must be considered when calculating sponsor reporting periods expressed in working days.

Where a public holiday is excluded under the applicable Home Office definition, it is not counted as one of the permitted working days.

However, employers should not assume that every regional or local holiday automatically extends the deadline.

The calculation must follow the definition contained in the relevant Home Office guidance.

For planning purposes, employers can consult the official UK bank holiday calendar:

UK bank holidays – GOV.UK.

The employer should use the official calendar alongside the applicable sponsor guidance, rather than treating the calendar itself as the legal definition of a working day.

Employer example: A reportable event occurs shortly before the Christmas and New Year period.

The sponsor should identify the relevant reporting trigger and exclude the public holidays specified by the applicable Home Office rules.

It should also make arrangements for the notification to be completed despite reduced staffing during the holiday period.

 

7. What happens if the reporting trigger falls on a weekend or public holiday?

 

A reportable event can occur on a day that is not counted as a working day for the purposes of the notification period.

For example, a sponsored worker’s employment may end on a Saturday, or a corporate transaction may complete on a public holiday.

The employer must still identify the correct reporting trigger under the applicable Home Office provision.

It should then calculate the permitted working days using the relevant counting convention.

The fact that the event occurred outside the employer’s normal office hours does not remove the reporting obligation.

Employers should ensure that their internal reporting arrangements can identify relevant events occurring during weekends, holiday periods or other times when the immigration compliance team is not routinely working.

 

8. How is the deadline calculated for unauthorised absence?

 

Unauthorised absence is subject to a specific reporting rule.

Where a sponsored worker is absent from work without permission for more than 10 consecutive working days, the Home Office requires the sponsor to report the absence no later than 10 working days after the tenth day of absence.

The calculation therefore involves two separate stages.

 

1. Establish the absence threshold: Identify the tenth consecutive working day of unauthorised absence.
2. Calculate the notification deadline: Apply the subsequent 10 working day reporting period specified by the guidance.

 

Employers should not calculate the reporting deadline as simply 10 working days from the first day of absence.

Nor should they assume that the worker must have returned before the report can be submitted.

The employer should maintain accurate absence records, document attempts to contact the worker and establish whether sponsorship will continue.

Employer example: A sponsored worker fails to attend work without permission and remains absent beyond the tenth consecutive working day.

The sponsor should establish when the threshold was reached and calculate the subsequent reporting deadline.

Where the absence also results in termination of employment, the employer should separately assess the cessation-of-sponsorship reporting requirement.

 

9. How is the deadline calculated when a sponsored worker fails to start work?

 

The delayed commencement rules require employers to distinguish the initial permitted commencement period from the subsequent notification deadline.

Under the general Home Office provisions, the sponsor must assess whether the worker has commenced employment within the applicable 28-day period.

The start of that period depends on the relevant dates and circumstances specified in the sponsor guidance.

Where the worker does not commence within the permitted period and the reporting obligation applies, the sponsor must submit the relevant notification by the end of 10 working days after that period.

The calculation therefore involves:

 

1. Identifying the date from which the permitted commencement period is calculated.
2. Calculating the applicable 28-day period.
3. Determining whether the worker has commenced employment or an exception applies.
4. Calculating the subsequent 10 working day reporting deadline where notification is required.

 

Employers should not treat the initial 28-day period as 28 working days.

They should also avoid assuming that the reporting deadline begins automatically on the originally anticipated employment start date.

Employer compliance point: The commencement rules can also affect whether the sponsor is permitted to continue sponsoring the worker. The employer must therefore assess the substantive sponsorship position as well as the reporting deadline.

 

10. How should employers calculate deadlines for salary or location changes?

 

Where a change to a sponsored worker’s salary or normal work location is reportable, the employer should identify the event that triggers the applicable notification requirement.

This may require distinguishing between the date a change is agreed and the date it takes effect.

For example, an employer may agree a salary reduction several weeks before the revised salary becomes effective.

The sponsor should assess the immigration implications before implementation and calculate the reporting deadline using the relevant Home Office provision.

Similarly, a worker may be notified of a future relocation before their normal work location actually changes.

The employer should establish whether the proposed arrangement is reportable and identify the correct trigger.

The date on which payroll or HR records are updated should not automatically be treated as the reporting trigger.

 

11. Can several reporting deadlines run at the same time?

 

Yes. A single business event can create several reporting obligations, each with its own trigger and deadline.

For example, an organisational restructuring may involve changes to the sponsor’s registered details, the closure of a business site and the relocation of sponsored workers.

The organisational changes may fall within the 20 working day reporting framework, while reportable worker location changes may fall within the 10 working day framework.

The relevant periods may also begin on different dates.

Employers should therefore record each obligation separately rather than assuming that one deadline applies to the entire restructuring.

Employer example: A company changes its registered address on 2 November 2026 and relocates several sponsored workers on 16 November 2026.

The sponsor should assess the organisational address change and the workers’ location changes independently.

Where separate notifications are required, the employer should calculate the applicable deadlines using the relevant reporting triggers.

One SMS submission does not necessarily satisfy every associated reporting requirement.

 

12. Does late discovery of a change extend the deadline?

 

Late discovery does not automatically extend a sponsor reporting deadline.

Where the applicable rule is linked to the occurrence of a worker-related event, a delay in informing the immigration compliance team does not necessarily create a new reporting period.

For organisational changes governed by the general awareness-based provision, the employer should establish when the sponsoring organisation became aware of the change.

The date on which an individual Level 1 User receives the information may not be the relevant awareness date.

Where an employer discovers that a notification may already be overdue, it should establish the original trigger, calculate the deadline and take appropriate corrective action.

The organisation should also investigate why the change was not identified or escalated earlier.

Employer example: A payroll audit identifies a reportable salary reduction that took effect several weeks earlier.

The sponsor should establish the applicable reporting trigger and determine whether the notification deadline has expired.

It should not simply calculate a new 10 working day period from the date of the audit.

The employer should also assess whether the salary reduction affected the worker’s continued immigration eligibility.

 

13. What if the SMS is unavailable on the reporting deadline?

 

Technical difficulties with the Sponsor Management System can create a risk of late reporting.

Employers should therefore avoid leaving required notifications until the final permitted working day.

Where an SMS problem prevents a report from being submitted, the sponsor should follow the applicable Home Office procedure for reporting or escalating the technical issue.

The organisation should retain contemporaneous evidence of the difficulty, including:

 

• The date and time the problem occurred.
• The nature of the error or access failure.
• Any relevant error messages or screenshots.
• Attempts made to access or use the system.
• Communications with the relevant Home Office support service.
• The date the notification was eventually submitted.

 

The employer should not assume that an SMS outage automatically extends a statutory or policy reporting deadline.

It should take reasonable steps to resolve the issue promptly and retain evidence explaining any delay.

Appropriate SMS access arrangements are also important. Following the September 2026 changes to Level 2 User arrangements and the introduction of mandatory multi-factor authentication, sponsors should ensure that authorised Level 1 Users can access the system when reporting obligations arise.

 

14. Should employers use an internal deadline shorter than the Home Office deadline?

 

Yes. Employers should distinguish between the maximum Home Office reporting period and the internal timeframe for identifying, reviewing and submitting notifications.

The Home Office deadline is the external compliance limit. It should not be treated as the organisation’s target date for beginning the reporting process.

For example, an employer may require line managers to notify HR of potentially reportable changes within one or two working days of becoming aware of them.

The immigration compliance team can then assess the event, establish the reporting trigger and arrange the necessary SMS action.

Internal targets should allow sufficient time to:

 

• Confirm the facts and relevant dates.
• Determine whether the event is reportable.
• Identify the correct Home Office reporting provision.
• Calculate the applicable deadline.
• Obtain any required supporting information.
• Assess whether additional immigration action is necessary.
• Submit the notification through the correct procedure.
• Retain evidence of completion.

 

This approach reduces the risk of missed deadlines caused by delayed internal communication, staff absence or technical difficulties.

 

15. How should employers document their deadline calculations?

 

Employers should retain an auditable record of how each sponsor reporting deadline was calculated.

A central reporting register should identify the relevant event, the applicable reporting provision and the date used as the trigger.

It should also record the calculated deadline, the person responsible for submission and the date the notification was completed.

A practical reporting record may include:

 

Field	Information to record
Reportable event	Description of the worker or organisational change.
Applicable reporting rule	Relevant Home Office notification requirement.
Event date	Date the underlying change occurred.
Awareness date	Date the sponsor became aware, where relevant.
Reporting trigger	Date or circumstance starting the notification period.
Deadline	Calculated final submission date.
Responsible person	Authorised individual responsible for the report.
Submission date	Date the notification was completed.
Supporting evidence	Records supporting the event, calculation and submission.
Additional action	Any separate licence, immigration or right to work requirement.

 

Where the calculation involves a specific exception or unusual circumstances, the employer should record the basis of its assessment.

This can help demonstrate that the sponsor has applied a consistent process and provide evidence during a Home Office compliance inspection.

Employer compliance point: A reliable reporting process should allow the organisation to explain not only when a notification was submitted, but also why that deadline applied and how it was calculated.

Section G: How Do Employers Submit Sponsor Licence Reports to the Home Office?

 

Most routine sponsor licence notifications are submitted through the Home Office Sponsor Management System (SMS). The SMS is the online system used by licensed sponsors to manage their sponsorship activities, including reporting specified changes affecting sponsored workers and the sponsoring organisation.

Employers must ensure that reports are submitted through the correct SMS function, by an appropriately authorised user and within the applicable Home Office deadline.

However, submitting a notification is not always the same as obtaining approval for a change. Some circumstances require supporting documents, a separate licence change request or a new sponsor licence application. Changes to a sponsored worker’s employment may also require a separate immigration application.

The reporting process should therefore begin with an assessment of the underlying event, rather than simply selecting an SMS reporting function.

Employers should establish what has changed, whether the event is reportable, when the deadline expires and what information or evidence is required.

They should also retain an auditable record of the notification and any subsequent Home Office correspondence.

 

1. What is the Sponsor Management System?

 

The Sponsor Management System is the Home Office’s online platform for administering sponsor licences and carrying out specified sponsorship functions.

Licensed employers use the SMS to manage information concerning their sponsored workers, Certificates of Sponsorship, authorised users and relevant sponsor licence details.

Depending on the organisation’s licence and the permissions of the individual user, SMS functions may include:

 

• Assigning Certificates of Sponsorship.
• Reporting specified changes affecting sponsored workers.
• Requesting changes to sponsor licence details.
• Managing authorised SMS users.
• Reviewing relevant sponsorship information.
• Submitting certain requests concerning the organisation’s licence.

 

The SMS is also an important component of the Home Office’s oversight of licensed sponsors.

Information submitted through the system may be considered during compliance activity, including sponsor licence audits, investigations and decisions concerning the organisation’s continued suitability to hold a licence.

Employers should therefore ensure that SMS records are accurate, notifications are timely and submissions are supported by appropriate evidence.

 

2. Which SMS function is used to report changes affecting sponsored workers?

 

For many worker-related notifications, the relevant SMS function is Report migrant activity.

This function is used to notify the Home Office of specified developments affecting sponsored workers, including relevant changes to employment or sponsorship circumstances.

Depending on the event and the applicable guidance, these may include:

 

• A sponsored worker failing to commence employment within the permitted period.
• The employer ceasing to sponsor a worker.
• Unauthorised absence exceeding the relevant threshold.
• Certain changes to the worker’s employment arrangements.
• Other worker-related events requiring notification through the SMS.

 

The sponsor should identify the reporting category that corresponds to the particular event and provide the information required by the system and the Home Office guidance.

The employer should not assume that every worker-related change is reported through the same SMS option.

Where the relevant change requires a different procedure, the sponsor must follow the applicable Home Office instructions.

Employer example: A sponsored worker resigns and their employment ends before the date originally anticipated.

The sponsor should establish the cessation-of-sponsorship reporting requirement, calculate the applicable deadline and submit the relevant notification through the appropriate SMS function.

It should retain evidence of the worker’s departure and the completed report.

 

3. How are changes to the sponsoring organisation reported?

 

Many organisational changes are submitted through the SMS using functions available to an appropriately authorised Level 1 User.

Depending on the nature of the change, the relevant function may include Request changes to licence details.

Changes affecting authorised SMS users may be managed through the applicable user-management facilities.

The employer should establish which procedure applies before attempting to submit the notification.

For example, a change to the organisation’s registered business address may require a different process from replacing the Authorising Officer or notifying the Home Office of a corporate acquisition.

Some changes may require the submission of supporting documents or additional information.

In limited circumstances, the Home Office may require a sponsor change of circumstances form or another prescribed procedure.

Employers should also distinguish between submitting information about a change and obtaining any necessary Home Office approval.

Where a request requires consideration by the Home Office, the sponsor should monitor its progress and respond to requests for further evidence.

 

4. Who can submit sponsor licence reports through the SMS?

 

Sponsor licence reports must be submitted by an individual with the appropriate SMS permissions.

The Home Office operates a system of authorised users, with different permissions depending on the user’s role.

The Level 1 User is responsible for carrying out key day-to-day sponsorship administration functions and has access to the relevant SMS facilities associated with that role.

The organisation should ensure that it has appropriate Level 1 User arrangements in place to meet its reporting obligations.

The Authorising Officer remains responsible for appropriate oversight of the organisation’s compliance with its sponsor duties, even where another individual undertakes the routine SMS administration.

The employer should not assume that delegating SMS activity transfers the organisation’s legal responsibility for compliance to the individual user.

Employer compliance point: Responsibility for complying with sponsor reporting duties rests with the licensed sponsoring organisation. The SMS user performs the relevant administrative action on its behalf.

 

5. What is the role of the Level 1 User in sponsor reporting?

 

The Level 1 User is central to the administration of the sponsor licence.

Depending on the applicable permissions, the Level 1 User may undertake functions including reporting changes, managing sponsorship records, assigning Certificates of Sponsorship and requesting amendments to licence details.

Employers should ensure that Level 1 Users understand the reporting requirements relevant to their organisation.

This includes knowing:

 

• Which changes must be reported.
• Which reporting deadline applies.
• How the reporting trigger is determined.
• Which SMS function should be used.
• What supporting information is required.
• When a separate licence request or immigration application may be necessary.
• How evidence of the notification should be retained.

 

The employer should also ensure that Level 1 Users receive timely information from HR, payroll, line managers and corporate functions.

An SMS user cannot reliably meet a reporting deadline if the underlying change is not communicated until after the permitted period has expired.

Appropriate training, documented procedures and access to current Home Office guidance are therefore important.

 

6. Can Level 2 Users still submit sponsor reports?

 

The Home Office has introduced changes to the Level 2 User role.

From 9 September 2026, restrictions were introduced on adding new Level 2 Users. The role is scheduled to be removed entirely after 8 March 2027.

Existing Level 2 Users may continue to have access to functions permitted under the transitional arrangements while those arrangements remain in force.

However, employers should not rely on appointing additional Level 2 Users as a future solution for sponsor reporting continuity.

Instead, the organisation should review its Level 1 User arrangements and ensure that appropriately authorised individuals can complete the necessary SMS functions.

This is particularly important where an existing user leaves the organisation, becomes unavailable or loses access to the system.

Employers should check the current Home Office user-management requirements before making changes to their SMS access arrangements.

 

7. Can an immigration adviser submit SMS reports for an employer?

 

An employer may obtain assistance from an immigration adviser or legal representative in managing its sponsor licence and reporting obligations.

However, access to the SMS must comply with the Home Office’s rules governing authorised users and representatives.

The organisation should not assume that an external adviser can access every SMS function or act in place of an appropriately authorised user without satisfying the relevant requirements.

Where an adviser assists with reporting, the sponsor should establish:

 

• Whether the adviser is permitted to undertake the relevant function.
• What SMS access or authorisation is required.
• Who is responsible for identifying reportable changes.
• Who will calculate and monitor the deadlines.
• Who will submit the notification.
• How evidence of the submission will be retained.

 

The sponsor remains responsible for compliance with its reporting duties.

Outsourcing administrative support does not remove the organisation’s obligation to identify changes and ensure that notifications are completed within the prescribed period.

 

8. What information is needed to submit a sponsor report?

 

The information required depends on the nature of the reportable event.

For worker-related notifications, the sponsor may need to provide identifying details of the worker, the relevant Certificate of Sponsorship information and an explanation of the change.

Depending on the reporting category, additional information may include:

 

• The date the relevant event occurred.
• The worker’s last day of employment.
• The reason sponsorship has ended.
• The nature and effective date of a change to employment arrangements.
• Details of a revised work location.
• Relevant salary information.
• Information concerning an unauthorised absence.
• Whether the organisation intends to continue sponsorship.

 

For organisational changes, the employer may need to provide updated company details, an explanation of the change and supporting evidence.

Employers should obtain the required information before attempting to complete the notification wherever possible.

Incomplete or inaccurate reporting can create further compliance problems, particularly where the Home Office relies on the information to assess whether sponsorship remains valid.

 

9. What information must be included in an unauthorised absence report?

 

Where a sponsored worker is absent without permission for more than 10 consecutive working days, the sponsor must comply with the specific Home Office reporting requirements.

The notification should include the information required by the applicable guidance.

This may include:

 

• The date the unauthorised absence began.
• The date the worker returned, where applicable.
• The reason for the absence, if known.
• Attempts made by the employer to contact the worker.
• Any relevant deductions from the worker’s salary.
• Whether the employer intends to continue sponsoring the worker.

 

The employer should maintain accurate attendance records and evidence of its attempts to establish the worker’s circumstances.

Where the absence results in the termination of employment, the sponsor should also assess whether a separate cessation-of-sponsorship notification is required.

The reporting deadline for unauthorised absence must be calculated using the specific Home Office rule, rather than assuming that the period begins on the first day the worker fails to attend.

 

10. Do employers need supporting documents for SMS reports?

 

Supporting evidence requirements depend on the type of notification or request.

Some routine worker reports can be submitted using the relevant SMS function without the immediate submission of extensive supporting documents.

However, the employer must still retain records demonstrating the circumstances of the change and its compliance with sponsor duties.

Other requests, particularly those concerning organisational details or corporate changes, may require supporting documentation to be provided to the Home Office. Where an organisational SMS request generates a submission sheet, declaration or supporting-document requirement, these must be sent within 5 working days. Any further documents requested by the Home Office must also be provided within 5 working days.

Examples of relevant evidence may include:

 

• Employment termination letters.
• Revised employment contracts.
• Payroll and salary records.
• Attendance and absence records.
• Evidence of changes to work location.
• Company registration documents.
• Business address records.
• Documents concerning mergers, acquisitions or transfers.
• Records relating to changes in key personnel.

 

Employers should check whether supporting documents must be submitted as part of the particular request or retained for inspection.

They should not assume that an SMS notification alone satisfies every associated record-keeping requirement.

 

11. Does submitting an SMS report mean the Home Office has approved the change?

 

No. Employers must distinguish between notifying the Home Office of a change and obtaining any approval required for that change.

Some sponsor notifications are reporting obligations rather than applications for permission.

Submitting the report does not necessarily mean that the Home Office has approved the underlying employment arrangement or confirmed that the worker continues to satisfy the Immigration Rules.

For example, reporting a salary reduction does not make the reduction permissible if it causes the worker to fall below the applicable immigration salary requirements.

Similarly, reporting a material change in job duties does not replace a change of employment immigration application where one is required.

Organisational changes may also require separate approval, a licence change request or a new sponsor licence application.

Employers should establish whether the change can lawfully take effect before implementing it.

 

12. What happens after a sponsor report is submitted?

 

After submitting a notification, the employer should retain evidence of the submission and update its internal reporting records.

Depending on the nature of the report, the Home Office may process the information without requiring further action or may request additional details or supporting documents.

The sponsor should monitor any outstanding requests and respond within the applicable timeframe.

For organisational changes requiring Home Office consideration, the employer should not assume that the matter is complete merely because the initial SMS request has been submitted.

The organisation should record:

 

• The date the notification was submitted.
• The SMS function used.
• The relevant worker or organisational details.
• The information provided.
• Any submission reference or confirmation available.
• Supporting documents submitted or retained.
• Any subsequent Home Office correspondence.
• Whether additional action remains outstanding.

 

These records can help demonstrate compliance during an internal review or Home Office inspection.

 

13. What if an employer submits incorrect information through the SMS?

 

Incorrect or incomplete information submitted through the SMS should be addressed promptly.

The appropriate corrective action depends on the nature of the error and the reporting function involved.

For example, a minor administrative mistake may require a different response from an incorrect notification concerning the termination of sponsorship or a material change to the worker’s employment.

The employer should establish:

 

1. What information was submitted incorrectly.
2. Whether the error affects the accuracy of the Home Office’s sponsorship records.
3. Whether the original reporting deadline was met.
4. Which procedure is available to correct the information.
5. Whether the error creates wider immigration compliance concerns.

 

The organisation should retain evidence of the original submission, the error identified and the corrective action taken.

Where the issue could materially affect the worker’s immigration position or the sponsor licence, specialist advice may be appropriate.

 

14. What should employers do if the SMS is unavailable?

 

Technical problems with the Sponsor Management System can interfere with the submission of time-sensitive reports.

Employers should take reasonable steps to address access or system problems promptly and follow the applicable Home Office support procedures.

Where a technical problem prevents a required notification from being completed, the sponsor should retain contemporaneous evidence of the issue.

This may include:

 

• The date and time of the attempted submission.
• The nature of the technical problem.
• Relevant error messages or screenshots.
• Attempts to access or use the SMS.
• Any communications with Home Office technical support.
• The steps taken to resolve the problem.
• The date the report was eventually submitted.

 

Employers should not assume that a technical failure automatically extends the reporting deadline.

Where a deadline has been missed, the organisation should address the outstanding notification as soon as possible and retain evidence explaining the circumstances.

Internal procedures should also ensure that an SMS access problem is escalated promptly rather than being left unresolved until after the deadline.

 

15. How does multi-factor authentication affect sponsor reporting?

 

The Home Office introduced mandatory multi-factor authentication for SMS users from 3 September 2026.

Employers must ensure that authorised users can complete the relevant authentication requirements and access the system when necessary.

Problems with authentication can create operational risks where a report is approaching its deadline.

The organisation should therefore maintain appropriate access arrangements and ensure that users understand the applicable sign-in procedures.

Employers should also review their arrangements for staff departures, absences and changes to authorised users.

SMS access should not depend on a single individual being available at all times.

However, continuity arrangements must comply with the Home Office’s rules concerning authorised users and account security.

Employers should not share individual SMS credentials or bypass authentication requirements as a means of meeting a reporting deadline.

 

16. How should employers manage SMS reporting when a Level 1 User is absent?

 

Employers should establish arrangements to ensure that sponsor reporting obligations can still be fulfilled when an individual Level 1 User is unavailable.

This may involve maintaining appropriate additional Level 1 User coverage in accordance with the current Home Office requirements.

The organisation should review whether authorised users have the necessary permissions, training and access to complete relevant functions.

It should also ensure that reporting information is stored in an accessible compliance system rather than being held exclusively by one employee.

Relevant continuity arrangements may include:

 

• Identifying appropriately authorised Level 1 Users.
• Maintaining current SMS access arrangements.
• Providing training on reportable events and deadlines.
• Using a central reporting register.
• Establishing escalation procedures for urgent notifications.
• Reviewing outstanding reporting obligations during staff handovers.

 

Following the September 2026 restrictions on Level 2 Users, employers should ensure that their arrangements reflect the current Home Office user-management framework.

 

17. Can an employer submit a late sponsor report through the SMS?

 

Where a reporting deadline has been missed, the employer should establish whether the required notification can still be submitted through the relevant SMS function.

The availability of a particular reporting option and the appropriate corrective procedure may depend on the event and the system’s current functionality.

The sponsor should not assume that a late report is unnecessary merely because the deadline has passed.

Equally, submitting a late notification does not automatically remove the original breach.

The employer should identify the relevant reporting trigger, establish how late the notification is and retain evidence explaining the circumstances.

Where the matter involves a material sponsorship change or possible breach of immigration requirements, legal advice may be appropriate.

The organisation should also consider whether the missed deadline indicates a wider weakness in its reporting procedures.

 

18. How do SMS reports interact with right to work obligations?

 

Sponsor reporting and right to work checking are separate compliance obligations.

Submitting a notification through the SMS does not replace a compliant right to work check or any required re-verification of a worker’s immigration status.

Similarly, completing a right to work check does not remove the sponsor’s obligation to report specified changes affecting sponsored employment.

Following the changes to the right to work framework effective from 1 October 2026, employers should ensure that their procedures account for the wider categories of working arrangements brought within the applicable checking regime.

Where a sponsored worker’s employment or engagement arrangements change, the employer should consider whether:

 

• An SMS notification is required.
• The worker remains permitted to undertake the relevant work.
• A right to work check or re-verification is required.
• Evidence of a check undertaken by another organisation must be obtained or retained.
• The arrangement affects the sponsor’s record-keeping or monitoring duties.

 

The Home Office’s Appendix D sponsor record-keeping guidance should be considered where another organisation is involved in the worker’s employment or engagement.

Employers should maintain coordinated but distinct procedures for SMS reporting and right to work compliance.

 

19. What evidence should employers retain after submitting an SMS report?

 

Employers should retain sufficient evidence to demonstrate that a required sponsor notification was submitted within the applicable deadline.

The records should establish both the underlying event and the reporting action taken.

Depending on the circumstances, relevant evidence may include:

 

• Documents confirming the reportable change.
• The date the relevant event occurred.
• The applicable reporting trigger.
• The calculated Home Office deadline.
• The identity of the authorised SMS user.
• The date the notification was submitted.
• Any available submission confirmation or reference.
• Supporting documents provided to the Home Office.
• Subsequent Home Office correspondence.
• Records of any additional immigration action required.

 

The organisation should retain these records in accordance with the applicable Home Office sponsor guidance and relevant data protection requirements.

Evidence of timely reporting can be particularly important where the Home Office later examines the employer’s compliance history.

 

20. What should an employer’s SMS reporting procedure include?

 

A documented SMS reporting procedure should explain how the organisation identifies, assesses, submits and records sponsor notifications.

It should allocate responsibility for each stage and provide a clear process for dealing with urgent or uncertain cases.

The procedure should include:

 

1. Identification: HR, payroll, line managers and corporate teams identify potentially reportable changes.
2. Escalation: The relevant information is referred promptly to the immigration compliance function.
3. Assessment: The organisation determines whether the event is reportable and whether additional immigration action is required.
4. Deadline calculation: The applicable reporting trigger and final submission date are established.
5. Information gathering: Supporting facts and documents are obtained.
6. Submission: An appropriately authorised user completes the correct SMS action or other prescribed procedure.
7. Verification: The organisation checks that the notification has been submitted and records any outstanding requirements.
8. Record keeping: Evidence of the event, deadline and submission is retained.
9. Follow-up: Any Home Office requests or separate immigration requirements are addressed.
10. Review: Reporting records are periodically reconciled against HR, payroll and organisational information.

 

Employers should also establish contingency arrangements for staff absence, technical failures and changes to authorised SMS users.

Employer compliance point: Effective SMS reporting requires more than access to the Home Office system. The sponsor must have reliable procedures for identifying reportable events, calculating deadlines, submitting accurate information and retaining evidence that its obligations have been fulfilled.

Section H: What Happens If a Sponsor Misses a Home Office Reporting Deadline?

 

Missing a mandatory sponsor licence reporting deadline can amount to a breach of the employer’s duties as a licensed sponsor. The Home Office expects sponsoring organisations to identify reportable changes, submit notifications within the applicable period and maintain accurate records demonstrating compliance.

A reporting failure may arise because the employer does not recognise that an event is reportable, calculates the deadline incorrectly, experiences delays in internal communication or fails to complete the required notification through the Sponsor Management System (SMS).

The consequences depend on the circumstances. A late report does not automatically result in sponsor licence revocation, but it can expose the organisation to compliance action, particularly where the failure forms part of wider weaknesses in sponsorship management.

The Home Office may consider the seriousness of the breach, whether it is isolated or repeated, its impact on immigration control and whether the employer has maintained effective systems for meeting its sponsor duties.

Depending on the circumstances and the applicable enforcement provisions, action may include a compliance investigation, licence downgrading, suspension or revocation.

Employers should also distinguish a breach of sponsor reporting duties from other immigration compliance failures. For example, a failure to submit an SMS notification is not the same as employing a person without the necessary right to work checks, although both issues may arise from the same underlying circumstances.

 

1. Is missing a sponsor reporting deadline a breach of sponsor duties?

 

Yes. Where the Home Office requires a licensed sponsor to report a specified event within a prescribed period, failure to meet that deadline can constitute a breach of sponsor duties.

The reporting requirements form part of the obligations accepted by an organisation when it obtains and maintains a sponsor licence.

These duties are not limited to submitting information when requested by the Home Office. Sponsors are expected to monitor relevant employment and organisational developments and report specified changes proactively.

A reporting breach may therefore arise where:

 

• A required notification is not submitted.
• A notification is submitted after the applicable deadline.
• The employer fails to identify a reportable change.
• Incorrect or incomplete information is provided.
• The organisation fails to follow a prescribed reporting procedure.
• A reportable event is identified but not escalated to an authorised SMS user in time.

 

The Home Office may assess the breach in the context of the sponsor’s wider compliance arrangements.

An isolated administrative failure may be treated differently from repeated reporting failures or conduct suggesting that the employer cannot adequately monitor its sponsored workforce.

 

2. Does a late sponsor report automatically result in licence revocation?

 

No. A late sponsor notification does not automatically result in revocation of the sponsor licence.

The Home Office operates a framework for assessing sponsor compliance failures and determining the appropriate enforcement response.

The action taken depends on the nature of the breach and the relevant provisions of the sponsor guidance.

For relatively minor compliance failures, the Home Office may consider whether licence downgrading and an action plan are appropriate.

More serious breaches may justify suspension or revocation, including circumstances in which the Home Office proceeds directly to revocation without first suspending the licence.

Employers should not assume that every late notification will be treated as a minor administrative issue.

For example, a late report concerning a sponsored worker’s change of work location may raise different concerns from a failure to notify the Home Office that an individual has stopped working for the sponsor but remains recorded as sponsored.

The employer should assess both the reporting failure and the underlying circumstances.

 

3. How does the Home Office assess the seriousness of a reporting breach?

 

The Home Office may consider a range of factors when assessing a sponsor reporting failure.

These can include the nature of the event, the length of the delay, the organisation’s compliance history and whether the breach indicates weaknesses in its sponsorship systems.

Relevant considerations may include:

 

• Whether the failure was isolated or repeated.
• How long the notification remained outstanding.
• Whether the employer maintained accurate underlying records.
• Whether the failure concealed or accompanied another immigration compliance issue.
• Whether the organisation continued sponsoring a worker in circumstances that required sponsorship to cease.
• Whether the sponsor had effective monitoring and escalation procedures.
• Whether the organisation identified and corrected the failure.
• Whether similar weaknesses have previously been identified by the Home Office.

 

These factors do not replace the specific enforcement provisions in the Home Office guidance.

Where the circumstances fall within a mandatory or normally mandatory revocation ground, the applicable rule may substantially limit the scope for a lesser enforcement response.

Employers should therefore assess the precise breach rather than relying solely on a general argument that the delay was unintentional.

 

4. Can the Home Office downgrade a sponsor licence for late reporting?

 

Yes. Reporting failures can contribute to a decision to downgrade a sponsor licence where the relevant Home Office enforcement provisions permit that response.

A sponsor licence may be downgraded from an A-rating to a B-rating where the Home Office identifies compliance weaknesses that it considers capable of being addressed through the applicable action plan process.

A B-rated sponsor is subject to restrictions and must comply with the requirements imposed by the Home Office.

The organisation may be required to implement an action plan addressing identified deficiencies in its sponsorship arrangements.

Where reporting failures are involved, the required improvements may concern:

 

• Procedures for identifying reportable changes.
• Internal communication between HR, payroll and line managers.
• Monitoring of sponsored workers’ employment circumstances.
• Deadline calculation and reporting controls.
• SMS access and authorised user arrangements.
• Record keeping and evidence retention.
• Training for individuals responsible for sponsor compliance.

 

Downgrading is not an automatic consequence of every missed reporting deadline.

The Home Office must consider the relevant circumstances and apply the applicable enforcement framework.

 

5. What happens if a sponsor is given a B-rating?

 

A B-rating indicates that the Home Office has identified deficiencies in the sponsor’s compliance arrangements and has imposed the relevant restrictions and improvement requirements.

The organisation may be required to comply with a formal action plan before its A-rating can be restored.

The action plan is intended to address the identified compliance weaknesses within the period specified by the Home Office.

A B-rated sponsor is generally restricted from assigning Certificates of Sponsorship to new workers, subject to the specific rules and exceptions applying to its circumstances.

This can have significant operational consequences for employers that depend on international recruitment.

Where the downgrade arises from reporting failures, the organisation should focus on correcting the underlying systems rather than simply submitting any outstanding notifications.

For example, repeated failures to report worker departures may indicate that the sponsor’s HR termination process is not properly connected to its immigration compliance procedures.

Corrective action may therefore require changes to internal workflows, accountability and monitoring arrangements.

Failure to comply with an action plan or remedy the relevant deficiencies may expose the organisation to further enforcement action.

 

6. Can a sponsor licence be suspended because of missed reporting deadlines?

 

Yes. Reporting failures may contribute to sponsor licence suspension where the Home Office considers that the circumstances justify investigation or enforcement action under the applicable guidance.

Suspension is generally used where the Home Office has concerns about the sponsor’s compliance and needs to consider whether further action, including revocation, is appropriate.

The consequences can be significant.

While the licence is suspended, the sponsor cannot assign any Certificates of Sponsorship.

The suspension may also affect planned recruitment, immigration applications and the employer’s ability to manage its sponsored workforce.

Suspension does not necessarily mean that all existing sponsored workers immediately lose their immigration permission.

However, the position may change if the Home Office subsequently revokes the licence or takes action affecting individual workers.

Employers facing suspension should assess the Home Office’s allegations carefully, preserve relevant evidence and respond within the applicable procedure and timeframe.

 

7. Can repeated reporting failures lead to sponsor licence revocation?

 

Yes. Repeated or serious failures to comply with sponsor reporting duties may contribute to a decision to revoke a sponsor licence.

Revocation is among the most serious enforcement outcomes because it removes the organisation’s authority to sponsor workers under the affected licence.

The Home Office guidance distinguishes between circumstances in which it will revoke a licence, will normally revoke a licence and may revoke a licence.

Employers should not treat these categories as interchangeable.

Some breaches engage mandatory revocation provisions, while others involve a different enforcement assessment.

Where reporting failures form part of a wider pattern of non-compliance, the Home Office may consider whether the sponsor has demonstrated that it can continue meeting its obligations.

Examples of potentially serious circumstances include:

 

• Repeated failures to report sponsored workers who have left employment.
• Persistent weaknesses in monitoring sponsored workers’ attendance or employment circumstances.
• Failure to report material changes affecting the continued validity of sponsorship.
• Reporting failures associated with workers undertaking employment outside their permitted sponsorship arrangements.
• Failure to address compliance deficiencies previously identified by the Home Office.
• Conduct involving inaccurate or misleading information provided to the Home Office.

 

The outcome depends on the precise facts and applicable enforcement provisions.

Employers should not assume that submitting overdue notifications will necessarily prevent revocation where more serious grounds are engaged.

 

8. What is the difference between mandatory and discretionary sponsor licence revocation?

 

The Home Office sponsor guidance identifies different categories of circumstances that may result in licence revocation.

These include grounds under which the Home Office will revoke, will normally revoke or may revoke a sponsor licence.

The distinction matters because it affects the Home Office’s approach to enforcement and the scope for considering the sponsor’s particular circumstances.

Where the guidance provides that the Home Office will revoke a licence, the relevant ground is treated as requiring revocation under the applicable policy.

Where the guidance states that it will normally revoke, the policy indicates that revocation is the expected outcome, subject to the relevant provisions and circumstances.

Where the guidance provides that the Home Office may revoke, the decision involves consideration of the applicable factors and the circumstances of the case.

A missed reporting deadline should therefore be assessed by reference to the specific breach and any associated conduct.

Employers should not assume that every reporting failure automatically falls within a discretionary enforcement category.

Equally, a late report should not be presented as an automatic mandatory revocation ground without identifying the relevant provision.

 

9. Can the Home Office investigate a sponsor because of reporting failures?

 

Yes. Reporting failures may prompt or contribute to Home Office compliance activity.

The Home Office can assess whether a licensed sponsor is meeting its duties through compliance checks, requests for information and visits to the organisation.

A compliance investigation may examine whether the employer has effective systems for monitoring sponsored workers and identifying reportable events.

Relevant records may include:

 

• Sponsored worker personnel files.
• Employment contracts and termination records.
• Attendance and absence records.
• Payroll and salary information.
• Work-location records.
• SMS reporting records.
• Internal compliance registers.
• Evidence of changes to organisational details.
• Records of internal reporting and escalation procedures.

 

The Home Office may compare information held on the SMS with the employer’s underlying records.

Discrepancies can raise concerns about whether the organisation has reported changes accurately and within the required deadlines.

Employers should therefore ensure that their sponsorship records are consistent, current and capable of supporting the information submitted to the Home Office.

 

10. Does missing a reporting deadline affect existing sponsored workers?

 

A missed reporting deadline does not automatically mean that every sponsored worker employed by the organisation loses their immigration permission.

However, enforcement action against the sponsor licence can have significant consequences for the sponsored workforce.

The effect depends on the Home Office action taken and the circumstances of the individual workers.

Where a sponsor licence is downgraded, the organisation may face restrictions on assigning new Certificates of Sponsorship, but existing sponsored workers do not automatically lose their permission solely because of the downgrade.

Where a licence is suspended, the position of existing workers is generally different from that arising on revocation.

If the licence is revoked, the Home Office may take action affecting the immigration permission of workers sponsored under that licence, subject to the applicable rules and individual circumstances.

Employers should therefore recognise that failures in sponsor compliance can affect workforce continuity, recruitment plans and the immigration position of sponsored employees.

 

11. What happens to sponsored workers if the licence is revoked?

 

Revocation removes the organisation’s authority to sponsor workers under the affected licence.

This can have serious consequences for individuals whose immigration permission depends on sponsorship by that employer.

The Home Office may cancel or curtail the permission of affected workers in accordance with the applicable Immigration Rules and policy.

The precise outcome depends on the worker’s circumstances and any relevant exceptions.

Affected workers may need to obtain alternative sponsorship, make a different immigration application or leave the UK if they no longer have a lawful basis to remain.

Employers should not assume that all workers are subject to an identical outcome or that every worker’s permission ends immediately upon revocation.

Where revocation is a realistic risk, the organisation should obtain advice on the potential consequences for its sponsored workforce and the steps that may be available.

 

12. Is there a fixed financial penalty for late sponsor reporting?

 

There is no general fixed monetary penalty imposed solely because a licensed sponsor submits an SMS notification after the applicable reporting deadline.

The principal consequences of a sponsor reporting breach arise under the Home Office’s sponsor compliance and enforcement framework.

These may include licence downgrading, suspension or revocation, depending on the circumstances.

However, the underlying event may also involve a separate legal breach carrying financial penalties.

For example, if a reporting failure is associated with illegal working, the employer may face consequences under the separate right to work and illegal working enforcement regime.

Employers should therefore distinguish between the consequences of failing to report and the consequences of the underlying conduct.

A late SMS notification is not itself equivalent to a civil penalty for illegal working.

 

13. Can an employer receive a civil penalty for illegal working?

 

Yes. Employers may face civil penalties where they employ individuals in circumstances that breach the applicable illegal working provisions and cannot establish the relevant statutory excuse.

Under the applicable civil penalty regime, penalties can reach up to £60,000 per illegal worker.

This is a separate enforcement framework from the sponsor licence reporting rules.

The changes to the right to work regime effective from 1 October 2026 also extend specified checking obligations to certain working arrangements beyond traditional employment.

Employers should therefore ensure that their procedures address both sponsor reporting duties and the right to work requirements relevant to the individuals they employ or engage.

For example, an employer may be required to report a change affecting a sponsored worker while also assessing whether the worker remains permitted to undertake the relevant employment.

Submitting an SMS notification does not create a statutory excuse against an illegal working civil penalty.

Equally, completing a right to work check does not remove a separate sponsor reporting obligation.

 

14. Can a missed reporting deadline affect future sponsor licence applications?

 

A history of sponsor compliance failures may be relevant to future Home Office decisions concerning an organisation’s sponsorship arrangements.

Where a licence has been revoked, the organisation may be subject to restrictions on applying for another sponsor licence, including an applicable cooling-off period.

The precise consequences depend on the reason for revocation and the relevant Home Office rules.

Even where the licence is not revoked, repeated reporting failures may affect the Home Office’s assessment of the organisation’s ability to comply with sponsor duties.

Employers should therefore consider the longer-term consequences of reporting weaknesses, particularly where international recruitment is central to their workforce strategy.

Maintaining accurate records and demonstrating effective corrective action can be important where the Home Office subsequently reviews the organisation’s compliance history.

 

15. Does voluntarily correcting a late report prevent enforcement action?

 

Voluntarily identifying and correcting a missed reporting obligation may be relevant to the employer’s overall compliance response.

However, submitting a late notification does not automatically remove the original breach or prevent the Home Office from taking enforcement action.

The employer should establish the reporting requirement, submit the outstanding notification where possible and retain evidence explaining the circumstances.

It should also assess whether the underlying event involved any separate immigration compliance issue.

For example, a late report concerning a salary reduction may require the employer to consider whether the sponsored worker continued to meet the applicable salary requirements.

Correcting the notification does not necessarily resolve a substantive breach of those requirements.

Employers should therefore avoid treating retrospective SMS reporting as a complete remedy for every compliance problem.

 

16. What if the employer missed the deadline because of an administrative error?

 

Administrative errors can lead to late sponsor reporting, particularly where responsibility is divided between HR, payroll, line management and the immigration compliance team.

Examples include:

 

• A line manager failing to notify HR of a worker’s departure.
• Payroll implementing a salary change without immigration review.
• An authorised SMS user being absent when a deadline expires.
• An incorrect reporting trigger being entered into the compliance register.
• A report being prepared but not successfully submitted.
• Organisational changes not being referred to the sponsor licence team.

 

The fact that a failure was unintentional does not automatically remove the reporting obligation or prevent enforcement action.

The employer should establish what happened, correct the outstanding issue and address the weakness that caused the failure.

Where the error indicates a broader problem with internal controls, a wider compliance review may be appropriate.

 

17. What if several sponsor reporting deadlines have been missed?

 

Multiple missed deadlines may indicate systemic weaknesses in the organisation’s sponsorship arrangements.

The Home Office may consider whether the sponsor has effective procedures for monitoring sponsored workers, identifying reportable changes and submitting notifications within the prescribed periods.

Employers discovering several overdue reports should avoid addressing each case in isolation without examining the wider cause.

A structured review should establish:

 

1. Which events were reportable.
2. When the relevant reporting triggers occurred.
3. Which deadlines were missed.
4. Whether the outstanding notifications can still be submitted.
5. Whether any underlying immigration compliance breaches occurred.
6. Whether the failures affected particular departments or reporting processes.
7. What corrective action is required.

 

The organisation should also consider whether the pattern of failures creates a material risk of Home Office enforcement action.

Where the findings indicate serious or repeated non-compliance, specialist legal advice may be appropriate.

 

18. Can missed reporting deadlines be identified during a Home Office compliance visit?

 

Yes. The Home Office may identify reporting failures by comparing the information held on the SMS with the sponsor’s employment, payroll and organisational records.

For example, an inspection may identify that a sponsored worker left employment several months earlier but remains recorded as sponsored.

It may also reveal that a reportable salary reduction, change of work location or organisational development was not notified within the applicable period.

The Home Office may examine whether the sponsor has reliable systems for identifying changes and maintaining accurate records.

Employers should therefore be able to explain how reporting obligations are managed and demonstrate that relevant notifications were completed.

A central reporting register, supported by submission evidence and underlying records, can help the organisation respond to compliance enquiries.

 

19. What should employers do immediately after discovering a missed deadline?

 

Where an employer identifies a missed sponsor reporting deadline, it should take prompt and proportionate corrective action.

The initial response should establish the facts, determine the applicable reporting requirement and assess whether the notification remains outstanding.

The employer should then consider the appropriate submission or corrective procedure.

Immediate priorities should include:

 

1. Confirming the nature of the reportable event.
2. Identifying the relevant Home Office reporting provision.
3. Establishing the correct reporting trigger and deadline.
4. Determining whether the required notification was submitted.
5. Submitting or correcting the report where possible.
6. Preserving evidence of the event and any delay.
7. Assessing whether the underlying circumstances create additional immigration compliance concerns.
8. Investigating why the deadline was missed.
9. Considering whether similar failures may have occurred.
10. Obtaining legal advice where the circumstances indicate material enforcement risk.

 

The employer should not alter records to conceal the original date of the event or create the appearance that a notification was submitted on time.

Accurate documentation is important both for internal compliance and for any subsequent Home Office enquiry.

 

20. How can employers reduce the enforcement risk associated with late reporting?

 

Employers should maintain effective systems for identifying reportable changes, calculating deadlines and submitting accurate notifications.

These systems should be supported by clear accountability, appropriate SMS access and regular monitoring.

Practical measures include:

 

• Maintaining a central sponsor reporting register.
• Requiring prompt escalation of relevant HR and payroll changes.
• Reviewing proposed changes to sponsored employment before implementation.
• Monitoring sponsored workers’ attendance and employment circumstances.
• Maintaining appropriate Level 1 User coverage.
• Providing training to staff involved in sponsorship administration.
• Retaining evidence of SMS submissions.
• Conducting periodic internal sponsor compliance audits.
• Investigating and correcting reporting failures promptly.
• Reviewing the wider immigration implications of reportable events.

 

Where reporting failures have already occurred, the employer should document the corrective action taken and assess whether its procedures are capable of preventing recurrence.

These measures do not guarantee that the Home Office will refrain from enforcement action, but they can help the organisation maintain effective sponsorship controls and identify compliance risks before they escalate.

Employer compliance point: A missed sponsor reporting deadline should be treated as a compliance issue requiring assessment, not merely an overdue administrative task. The appropriate response depends on the reporting breach, the underlying circumstances and whether the failure reveals wider weaknesses in the organisation’s ability to meet its sponsor duties.

Section I: What Should an Employer Do After Missing a Sponsor Licence Reporting Deadline?

 

Where an employer discovers that a sponsor licence reporting deadline has been missed, it should take prompt action to establish the extent of the breach, complete any outstanding notification and assess whether the underlying circumstances create additional immigration compliance risks.

A late notification should not simply be treated as an administrative oversight. The employer must consider why the report was missed, whether the information held by the Home Office remains accurate and whether the event affects the organisation’s continued compliance with its sponsor duties.

The appropriate response depends on the nature of the reportable change, the length of the delay and whether the underlying event involves a separate breach of the Immigration Rules or sponsor guidance.

For example, a delayed notification of a change of business address may raise different concerns from a failure to report that a sponsored worker has left employment, experienced a reportable salary reduction or transferred to another legal entity.

Submitting an overdue report may correct the outstanding notification, but it does not automatically remove the original reporting breach or resolve any separate immigration compliance issue.

Employers should therefore adopt a structured approach that addresses the immediate notification, the underlying event and the internal controls responsible for preventing similar failures.

 

1. Confirm whether the change was reportable

 

The first step is to establish whether the event was subject to a mandatory Home Office reporting requirement.

Not every employment or organisational change requires notification through the Sponsor Management System (SMS).

For example, ordinary salary increases generally do not require reporting, subject to specific exceptions, while certain salary reductions may be reportable.

Similarly, not every temporary change to a worker’s duties or location requires an SMS notification.

The employer should identify:

 

• The precise nature of the change.
• The sponsored worker or organisational details affected.
• The relevant Home Office reporting provision.
• Whether a reporting exception applies.
• Whether the change requires an SMS notification or another procedure.
• Whether separate immigration action is required.

 

Where the employer concludes that no notification was required, it should consider documenting the basis of that assessment.

This is particularly useful where the change is material or could later be examined during a Home Office compliance inspection.

 

2. Establish the original reporting trigger and deadline

 

Once the employer confirms that the change was reportable, it should establish when the reporting period began and when the notification should have been submitted.

The calculation must follow the Home Office provision governing the particular event.

For many worker-related changes, the relevant reporting period is linked to the occurrence of the reportable event.

For many organisational changes, the general 20 working day rule is linked to when the sponsoring organisation became aware of the change, subject to specific exceptions.

Certain events have their own triggers, including unauthorised absence and failure to commence sponsored employment within the applicable period.

The employer should record:

 

• The date the underlying event occurred.
• The date the change took effect, where different.
• The date the organisation became aware of the event, where relevant.
• The applicable reporting trigger.
• The original notification deadline.
• The date the failure was identified.
• The number of working days by which the deadline was missed.

 

The organisation should not automatically calculate a fresh reporting period from the date the immigration compliance team discovered the issue.

Where the deadline has already expired, that fact should be accurately recorded.

 

3. Submit the outstanding notification as soon as possible

 

Where a mandatory notification remains outstanding, the employer should establish the appropriate procedure for submitting it.

In many cases, the relevant report may still be submitted through the SMS.

However, the available procedure depends on the type of event and the system’s functionality.

The employer should ensure that the notification accurately reflects the original change and its relevant dates.

It should not alter the event date to make the submission appear to fall within the permitted reporting period.

Where the relevant SMS function is unavailable or the change requires a different procedure, the sponsor should follow the applicable Home Office instructions.

The employer should retain evidence of the corrective action taken, including the submission date and any subsequent correspondence.

Employer compliance point: A late report should be completed promptly where the applicable procedure permits, but submitting it does not automatically extinguish the original breach.

 

4. Should the employer explain why the report was late?

 

The employer should maintain an accurate internal record explaining why the reporting deadline was missed.

Where the applicable Home Office procedure provides for an explanation or the Home Office requests further information, the sponsor should provide a truthful and appropriately detailed account.

The explanation should distinguish between the underlying event, the reporting obligation and the circumstances that caused the delay.

Relevant matters may include:

 

• When the event occurred.
• When the organisation became aware of it.
• Why the event was not reported within the applicable deadline.
• When the failure was identified.
• What corrective action was taken.
• Whether the underlying sponsorship arrangements remained compliant.
• What measures have been introduced to prevent recurrence.

 

Employers should avoid speculative explanations or unsupported assertions that the failure was outside their control.

Where an internal administrative error caused the delay, the organisation should identify the error accurately and address the underlying process.

The sponsor should not assume that providing an explanation guarantees that the Home Office will take no enforcement action.

 

5. Check whether the underlying change creates a separate immigration breach

 

Correcting an overdue notification may not resolve the immigration consequences of the underlying event.

The employer should therefore assess whether the change affected the worker’s eligibility, the validity of the sponsorship arrangements or the organisation’s continued suitability to hold its licence.

Examples include:

 

• A salary reduction that may have caused a sponsored worker to fall below the applicable minimum salary requirement.
• A material change in job duties that may have required a change of employment immigration application.
• A sponsored worker continuing to work after the employer should have ceased sponsorship.
• A transfer of sponsored workers to another legal entity without the necessary sponsorship arrangements.
• A corporate acquisition requiring a new sponsor licence application.
• A change of working arrangements creating separate right to work compliance concerns.

 

The employer should assess the substantive immigration requirements independently of the reporting deadline.

An SMS notification does not make an otherwise impermissible employment arrangement lawful.

Where the underlying event creates a material immigration compliance concern, the employer should obtain appropriate advice before taking further action.

 

6. What if the missed report concerns a sponsored worker leaving employment?

 

Where the employer discovers that a sponsored worker’s departure was not reported, it should establish the actual date on which employment or sponsorship ceased.

The sponsor should review the worker’s personnel records, termination documents and relevant payroll information.

It should then determine whether the required cessation-of-sponsorship notification was submitted and, if not, identify the appropriate corrective procedure.

The employer should retain evidence of:

 

• The worker’s final employment date.
• The circumstances in which employment ended.
• The original reporting deadline.
• The date the omission was discovered.
• The corrective notification submitted.
• Any relevant Home Office correspondence.

 

The employer should also consider whether the failure indicates a weakness in the process for communicating departures between line managers, HR and the immigration compliance team.

Employer example: An internal audit identifies that a sponsored worker resigned six weeks earlier, but no cessation-of-sponsorship notification was submitted.

The employer should establish the original reporting trigger, submit the outstanding notification through the appropriate procedure and investigate why the departure was not escalated.

It should also review other recent departures to establish whether similar omissions have occurred.

 

7. What if the missed report concerns a salary reduction?

 

A missed notification concerning a sponsored worker’s salary reduction requires particular care because the underlying change may affect the worker’s continued eligibility under the Immigration Rules.

The employer should first establish whether the reduction was reportable.

It should then review the revised salary against the requirements applicable to the worker’s immigration route and circumstances.

Relevant considerations may include:

 

• The worker’s sponsored occupation.
• The applicable salary threshold.
• Any relevant going rate requirement.
• Whether transitional provisions apply.
• The reason for the salary reduction.
• Whether a permitted exception applies.
• The date the revised salary took effect.
• Whether the worker’s hours or duties also changed.

 

Where the salary reduction is reportable, the employer should address the outstanding notification.

However, it must also determine whether the reduction was permissible under the applicable sponsorship rules.

Employer example: Payroll reduces a sponsored worker’s salary following an internal restructuring, but the immigration compliance team discovers the change two months later.

The employer should establish whether the salary change was reportable and calculate the original deadline.

It should then assess whether the worker continued to satisfy the applicable salary requirements throughout the relevant period.

Where the reduction was not permitted, retrospective SMS reporting alone will not resolve the substantive immigration compliance issue.

 

8. What if the missed report concerns unauthorised absence?

 

Where a sponsor discovers that an unauthorised absence notification was missed, it should establish the worker’s attendance history and the date on which the Home Office reporting threshold was reached.

The relevant rule requires reporting where a sponsored worker is absent without permission for more than 10 consecutive working days, with the notification due no later than 10 working days after the tenth day of absence.

The employer should review:

 

• The first day of unauthorised absence.
• The worker’s normal working pattern.
• The tenth consecutive working day of absence.
• The applicable reporting deadline.
• Attempts made to contact the worker.
• Any explanation subsequently provided.
• Whether the worker returned to work.
• Whether sponsorship continued or ended.

 

Where the reporting obligation was missed, the employer should address the outstanding notification and assess whether any separate cessation-of-sponsorship report is required.

The organisation should also examine whether its attendance monitoring procedures are sufficiently reliable to identify future reporting thresholds.

 

9. What if the missed deadline concerns a merger, acquisition or TUPE transfer?

 

Corporate transactions require particular care because the relevant Home Office obligations may extend beyond reporting a change through the SMS.

A merger, acquisition, ownership change or business transfer may affect the legal entity authorised to sponsor workers.

In specified circumstances, the Home Office rules require a new sponsor licence application within 20 working days.

Where an employer discovers that a relevant corporate change deadline has been missed, it should establish:

 

• The legal entities involved in the transaction.
• The date the transaction or transfer took effect.
• Which organisation held the relevant sponsor licence.
• Which organisation employed the sponsored workers before and after the transaction.
• Whether the existing sponsor licence remained valid for the arrangements.
• Whether notifications were required from the transferring or receiving organisation.
• Whether a new sponsor licence application was required.
• Whether any applicable application deadline has expired.

 

The employer should not assume that submitting a late organisational change notification resolves a failure to make a required new licence application.

Employer example: Company A acquires part of Company B’s business, including several sponsored workers, but the immigration implications are not reviewed until after the transaction completes.

The organisations should urgently establish whether the transfer required a new sponsor licence application and whether the applicable deadline has been missed.

They should also assess the immigration position of the affected workers and any outstanding reporting obligations.

Given the potential consequences for the validity of sponsorship, specialist immigration advice should be obtained promptly.

 

10. Should the employer conduct an internal investigation?

 

Where a sponsor reporting deadline has been missed, the employer should consider whether the circumstances justify an internal compliance investigation.

The purpose is to establish why the failure occurred, whether it is isolated and what corrective action is necessary.

The scope of the investigation should be proportionate to the seriousness of the issue.

A single administrative error may require a focused review, while repeated failures or concerns affecting sponsored workers’ immigration eligibility may justify a wider sponsor compliance audit.

The investigation should consider:

 

• How the reportable event arose.
• Which department first became aware of the change.
• Whether internal reporting procedures were followed.
• Whether the relevant deadline was correctly calculated.
• Whether an authorised SMS user was available.
• Whether supporting information was obtained promptly.
• Whether similar failures may have occurred.
• Whether the organisation’s records remain accurate.

 

The findings should be documented, together with any corrective action and responsibility for implementation.

 

11. Should employers review other sponsored workers and reporting records?

 

Yes, where the circumstances suggest that the missed deadline may reflect a wider weakness in the organisation’s reporting arrangements.

For example, a failure to report a sponsored worker’s departure may indicate that termination information is not consistently referred to the immigration compliance team.

The employer should consider reviewing other recent departures to establish whether the same problem has affected additional workers.

Similarly, an unreported salary reduction may justify reconciling payroll records against the information held on the SMS.

A targeted review may examine:

 

• Recent sponsored worker departures.
• Changes to salaries and working hours.
• Changes to job duties or occupations.
• Changes to normal work locations.
• Unauthorised absences.
• Delayed employment commencements.
• Changes to business addresses or premises.
• Corporate restructuring events.
• Changes to sponsor licence key personnel.

 

The employer should identify any additional reportable events and establish whether the applicable deadlines were met.

Where further omissions are discovered, they should be addressed through the appropriate corrective procedures.

 

12. What evidence should employers retain after correcting a missed report?

 

Employers should retain a clear audit trail of the original event, the reporting failure and the corrective action taken.

The evidence should allow the organisation to explain what happened and demonstrate the steps taken once the issue was identified.

Relevant records may include:

 

• Documents establishing the underlying change.
• The original event and reporting trigger dates.
• The calculated Home Office deadline.
• The date the failure was discovered.
• Internal correspondence concerning the event.
• Evidence of the late SMS notification or other corrective submission.
• Any explanation provided to the Home Office.
• Home Office correspondence or decisions.
• Records of any related immigration compliance assessment.
• Findings from an internal investigation.
• Evidence of remedial training or procedural changes.

 

Records should be retained in accordance with the applicable sponsor guidance and data protection requirements.

The employer should not retrospectively alter documents to suggest that a notification was submitted within the original deadline.

An accurate record is important both for internal governance and for responding to any subsequent Home Office enquiry.

 

13. Should the Authorising Officer be informed of missed reporting deadlines?

 

Material sponsor reporting failures should be escalated to the Authorising Officer and other appropriate senior personnel.

The Authorising Officer is responsible for appropriate oversight of the organisation’s compliance with its sponsor duties.

Although the Authorising Officer may not personally submit routine SMS notifications, they should have sufficient visibility of significant reporting failures and the action being taken to address them.

Escalation is particularly important where:

 

• Several reporting deadlines have been missed.
• The failure affects a worker’s continued immigration eligibility.
• A corporate transaction may have affected the validity of the sponsor licence.
• The Home Office has commenced compliance action.
• The organisation faces a material risk of suspension or revocation.
• Internal reporting systems appear inadequate.

 

The employer should establish clear criteria for escalating compliance incidents and ensure that senior management can authorise the necessary corrective action.

 

14. When should an employer obtain specialist immigration advice?

 

Specialist immigration advice may be appropriate where a missed reporting deadline creates uncertainty about the organisation’s compliance position or the immigration status of affected workers.

Particular circumstances include:

 

• Repeated or serious sponsor reporting failures.
• Salary reductions potentially breaching immigration requirements.
• Changes to sponsored employment that may have required new immigration permission.
• Unreported transfers of sponsored workers between legal entities.
• Missed deadlines associated with mergers, acquisitions or TUPE transfers.
• Possible invalidity of existing sponsorship arrangements.
• Home Office compliance investigations.
• Threatened sponsor licence suspension or revocation.
• Concerns about illegal working or right to work compliance.

 

Advice should address both the immediate reporting issue and any underlying immigration consequences.

Where a new sponsor licence application or immigration application may be required, the employer should establish the available options promptly.

Delaying assessment can increase the risk of further non-compliance.

 

15. Should employers notify the Home Office about every historic reporting error?

 

Employers should establish the reporting requirements applicable to each historic event rather than assuming that every administrative discrepancy requires the same notification.

Where a mandatory notification remains outstanding, the sponsor should identify the appropriate procedure for correcting the omission.

Where information was previously submitted incorrectly, the employer should establish whether an amendment, correction or further communication is required.

Some historic discrepancies may concern matters that were not reportable in the first place.

Others may reveal a more serious issue affecting the validity of sponsorship.

The employer should therefore distinguish between:

 

• An overdue mandatory notification.
• An inaccurate notification requiring correction.
• An administrative discrepancy that does not create a reporting obligation.
• A substantive immigration compliance breach requiring separate action.

 

Where the appropriate Home Office procedure is unclear, the sponsor should consult the current guidance and consider obtaining advice.

The organisation should avoid submitting speculative or inaccurate reports simply to demonstrate that some action has been taken.

 

16. Can a sponsor reporting breach be remedied through staff training?

 

Training can form part of the corrective response where a missed reporting deadline resulted from a lack of awareness or misunderstanding of sponsor duties.

However, training alone may not be sufficient where the organisation’s procedures are inadequate.

For example, a line manager may understand that a sponsored worker’s departure is reportable but still fail to notify the immigration compliance team if no formal termination workflow exists.

Effective remedial action may therefore require:

 

• Updated sponsor reporting procedures.
• Clear departmental responsibilities.
• Mandatory escalation of relevant employment changes.
• Training on 10 and 20 working day reporting requirements.
• Improved deadline monitoring.
• Appropriate Level 1 User access arrangements.
• Regular reconciliation of HR and SMS records.
• Periodic internal compliance reviews.

 

The employer should retain evidence of the measures implemented and review whether they are operating effectively.

 

17. How should employers prevent the same reporting failure happening again?

 

The organisation should use the findings from the missed deadline to strengthen its sponsor compliance arrangements.

The appropriate improvements depend on the cause of the failure.

For example, where a reporting deadline was missed because payroll implemented a salary reduction without immigration review, the employer may introduce a requirement for all proposed sponsored worker salary reductions to be approved by the immigration compliance function before implementation.

Where a worker’s departure was not reported, the employer may introduce a mandatory sponsorship check within its termination process.

Where SMS access problems caused the delay, the organisation may need to review its authorised user arrangements and authentication procedures.

A preventive action plan should identify:

 

1. The reporting weakness.
2. The corrective measure required.
3. The individual responsible for implementation.
4. The implementation deadline.
5. The evidence needed to demonstrate completion.
6. The process for testing whether the measure is effective.

 

Employers should also consider whether the same weakness could affect other sponsorship obligations, including record keeping, worker monitoring and right to work compliance.

 

18. What should employers do if the Home Office has already identified the breach?

 

Where the Home Office has identified a reporting failure, the employer should review the correspondence carefully and establish the procedure and deadline for responding.

The appropriate response depends on whether the Home Office has requested information, commenced a compliance investigation, suspended the licence or indicated that enforcement action is being considered.

The organisation should preserve relevant records and ensure that any response is accurate, complete and supported by evidence.

It should also establish whether the alleged reporting failure is correctly characterised under the applicable sponsor guidance.

Where the Home Office has misunderstood the facts or the relevant reporting trigger, the employer may need to explain the position with supporting documentation.

Where a breach has occurred, the organisation should address the facts and the corrective action taken.

Employers should not assume that the same response is appropriate for every stage of Home Office enforcement.

Where suspension or revocation is a possibility, specialist legal advice should be obtained promptly because the applicable procedure and response period may be critical.

 

19. Missed sponsor reporting deadline: corrective action checklist

 

The following checklist provides a practical framework for responding to an identified reporting failure.

 

Action	Purpose	Priority
Identify the underlying event	Establish precisely what changed and when.	Immediate
Confirm reportability	Determine whether a mandatory Home Office notification was required.	Immediate
Calculate the original deadline	Establish the reporting trigger and extent of any delay.	Immediate
Complete the outstanding notification	Address the reporting omission through the appropriate procedure.	As soon as possible
Review underlying immigration compliance	Identify any separate breach affecting sponsorship or worker eligibility.	Urgent where relevant
Preserve evidence	Maintain an accurate audit trail of the event and corrective action.	Immediate
Escalate material issues	Ensure appropriate Authorising Officer and senior management oversight.	Urgent where relevant
Investigate the cause	Determine why the reporting process failed.	Promptly
Review similar cases	Identify other potentially missed reporting obligations.	Risk-based
Implement corrective controls	Reduce the likelihood of recurrence.	Promptly
Obtain legal advice	Address material immigration or enforcement risks.	Urgent where relevant

 

The checklist should be adapted to the circumstances of the particular reporting failure.

Where the issue involves a corporate transaction, the employer should also establish whether a new sponsor licence application or other time-sensitive immigration action is required.

 

20. Can an employer demonstrate compliance improvement after a missed deadline?

 

Yes. Employers can document the corrective measures implemented following a sponsor reporting failure.

This may help demonstrate that the organisation has investigated the issue and strengthened its compliance arrangements.

Relevant evidence may include:

 

• A documented incident review.
• Updated sponsor reporting procedures.
• Revised HR and payroll escalation processes.
• Training records.
• An improved reporting register.
• Evidence of periodic compliance checks.
• Updated SMS access arrangements.
• Records demonstrating that subsequent notifications were submitted on time.

 

However, evidence of improvement does not automatically prevent the Home Office from taking enforcement action.

The outcome depends on the nature of the original breach and the applicable enforcement provisions.

Where the circumstances engage a mandatory or normally mandatory revocation ground, remedial action may not be sufficient to preserve the licence.

Employers should therefore treat compliance improvement as an essential operational response, rather than as a guaranteed defence to enforcement.

Employer compliance point: When a sponsor reporting deadline is missed, the priority is to establish the original obligation, correct the outstanding notification where possible, assess any underlying immigration breach and address the systems that allowed the failure to occur. The employer should be able to demonstrate what happened, what action was taken and how future reporting obligations will be managed.

Section J: Sponsor Licence Reporting Deadline Checklist for Employers

 

Employers holding a sponsor licence should maintain a documented process for identifying reportable changes, calculating Home Office deadlines and submitting notifications through the correct procedure.

A sponsor reporting checklist can help ensure that changes affecting sponsored workers and the sponsoring organisation are identified promptly and that the relevant information reaches an authorised Sponsor Management System (SMS) user before the reporting deadline expires.

The checklist should be incorporated into the organisation’s wider sponsor compliance arrangements, including HR administration, payroll, recruitment, attendance monitoring and corporate governance.

It should also distinguish between reporting obligations and other immigration requirements. A change may need to be reported to the Home Office while separately requiring a new immigration application, sponsor licence request or right to work compliance assessment.

The following checklist provides a framework for employers to adapt to their organisation’s size, workforce and sponsorship arrangements.

 

1. Identify all potentially reportable changes

 

Employers should establish a process for identifying events that may trigger a Home Office reporting obligation.

The process should cover both sponsored worker changes and changes affecting the sponsoring organisation.

Sponsored worker reporting checklist:

 

• Check whether any sponsored worker has failed to commence employment within the applicable permitted period.
• Identify workers whose employment or sponsorship has ended.
• Monitor unauthorised absence against the relevant reporting threshold.
• Monitor absence without pay or on reduced pay against the 4-week annual limit and permitted exceptions.
• Review changes to sponsored workers’ salaries and remuneration arrangements.
• Identify material changes to job duties or occupation.
• Review changes to normal work locations.
• Identify changes to working arrangements that may affect sponsorship requirements.
• Check whether any other event is reportable under the applicable immigration route.

 

Organisational reporting checklist:

 

• Review changes to the organisation’s registered or trading name.
• Identify changes to registered offices and relevant business addresses.
• Monitor changes involving branches and business premises.
• Identify changes to the nature of business activities.
• Review changes to ownership and corporate structure.
• Assess mergers, acquisitions, TUPE transfers and other business transactions.
• Identify relevant insolvency events.
• Review changes affecting regulatory approvals or registrations.
• Monitor changes to sponsor licence key personnel and authorised SMS users.

 

Not every change listed above necessarily requires an SMS notification. The employer must assess the particular event against the applicable Home Office guidance.

 

2. Confirm whether the change is reportable

 

Before submitting a notification, the employer should establish whether the relevant event falls within a mandatory reporting category.

The assessment should consider:

 

• The nature of the change.
• The immigration route under which the worker is sponsored, where relevant.
• The applicable Home Office sponsor guidance.
• Any specific reporting exceptions.
• Whether the event requires an SMS notification or another procedure.
• Whether the change creates additional immigration compliance requirements.

 

Where the employer concludes that a material change is not reportable, it should consider recording the basis of that decision.

Documenting the assessment can help demonstrate that the organisation considered its sponsor duties rather than overlooking the event.

 

3. Establish the correct 10 or 20 working day deadline

 

Once a reportable event has been identified, the employer should determine the applicable notification period.

The general reporting framework distinguishes between many worker-related changes, commonly subject to a 10 working day requirement, and many organisational changes, commonly subject to a 20 working day requirement.

However, specific provisions and exceptions apply.

 

Reporting category	General deadline	Important qualification
Reportable sponsored worker changes	Generally 10 working days	The reporting trigger depends on the particular event.
Reportable organisational changes	Generally 20 working days	The general rule is linked to organisational awareness, subject to exceptions.
Unauthorised absence	No later than 10 working days after the tenth day of absence	The absence must meet the relevant threshold.
Failure to commence sponsored employment	Generally by the end of 10 working days following the applicable 28-day period	The commencement period must be calculated under the specific Home Office rules.
Replacement of Authorising Officer or Key Contact	Specific provisions apply	Do not assume the general organisational awareness-based trigger applies.
Corporate change affecting sponsorship	Event-specific requirements	A new sponsor licence application may be required within 20 working days.

 

The employer should verify the applicable requirement before entering the deadline into its reporting register.

 

4. Record the reporting trigger and calculate the deadline

 

Employers should record the date or circumstance that starts the applicable reporting period.

The reporting trigger may be linked to the event occurring, the change taking effect, the organisation becoming aware of it or a specific threshold prescribed by the Home Office.

Deadline calculation checklist:

 

1. Identify the relevant Home Office reporting provision.
2. Record the underlying event date.
3. Record the effective date where different.
4. Record the organisation’s awareness date where relevant.
5. Identify the specific reporting trigger.
6. Determine whether the deadline is expressed in working days or calendar days.
7. Exclude weekends and relevant public holidays where required.
8. Calculate the final submission date.
9. Arrange for submission before the final permitted working day wherever possible.

 

The employer should not assume that the date an event reaches the immigration compliance team automatically starts a new reporting period.

 

5. Assign responsibility for the notification

 

Every reportable event should have an identified individual responsible for ensuring that the required notification is completed.

The employer should distinguish between the person identifying the change, the person assessing the reporting requirement and the authorised SMS user submitting the notification.

For example:

 

Function	Typical responsibility
Line manager	Identify changes to duties, work location, attendance or employment circumstances.
HR	Monitor employment commencement, termination, contracts and workforce changes.
Payroll	Identify salary and remuneration changes requiring immigration review.
Corporate or finance team	Escalate changes to business structure, ownership, premises or regulatory status.
Immigration compliance function	Assess reportability, calculate deadlines and coordinate notifications.
Authorised SMS user	Complete the applicable Home Office reporting or licence change procedure.
Authorising Officer	Maintain appropriate oversight of sponsor compliance and material risks.

 

The precise allocation of responsibilities will depend on the organisation’s structure.

However, the sponsor should ensure that accountability is clear and that reporting obligations are not dependent on informal communication between departments.

 

6. Check that the correct SMS function is used

 

Employers should confirm that the notification is submitted through the correct Home Office procedure.

For many sponsored worker changes, the relevant SMS function is Report migrant activity.

Organisational changes may require use of Request changes to licence details or another prescribed procedure.

Changes to authorised SMS users may be managed through the relevant user-management functions.

Some events require supporting documents, a sponsor change of circumstances form or a separate application.

SMS submission checklist:

 

• Confirm the correct reporting category.
• Identify the authorised user responsible for submission.
• Check that the user has the necessary permissions.
• Confirm the relevant worker or organisational details.
• Prepare the information required by the Home Office.
• Identify any supporting documents.
• Submit the notification through the correct procedure.
• Retain available evidence of submission.
• Monitor any subsequent Home Office requests.

 

The employer should not assume that an SMS notification constitutes approval for a change requiring separate immigration permission or sponsor licence authorisation.

 

7. Confirm that authorised SMS users have access

 

Employers should maintain appropriate SMS access arrangements to ensure that reporting obligations can be completed within the required deadlines.

Following the September 2026 changes to Level 2 User arrangements, sponsors should review their reliance on existing Level 2 Users and ensure that they have suitable Level 1 User coverage.

The Home Office introduced mandatory multi-factor authentication for SMS users from 3 September 2026.

Access management checklist:

 

• Confirm that authorised Level 1 Users remain appropriately appointed.
• Check that users can access the SMS.
• Ensure that authentication arrangements are operational.
• Review access when authorised users leave or change roles.
• Maintain appropriate continuity arrangements during staff absence.
• Ensure users understand the reporting functions relevant to their permissions.
• Do not share individual SMS credentials.

 

The employer should identify and resolve access problems before a reporting deadline becomes urgent.

 

8. Review whether additional immigration action is required

 

Some reportable events require more than an SMS notification.

The employer should assess whether the underlying change affects the worker’s immigration permission or the organisation’s authority to sponsor.

Additional action checklist:

 

• Does the change affect the worker’s eligibility under the Immigration Rules?
• Does a material change of employment require a new immigration application?
• Does a salary reduction affect the applicable salary threshold?
• Does the change involve a different sponsoring legal entity?
• Does a merger, acquisition or TUPE transfer require a new sponsor licence application?
• Does the change require supporting documents or Home Office approval?
• Does the event affect the organisation’s continued eligibility to hold a sponsor licence?
• Are there separate right to work or record-keeping requirements?

 

The employer should resolve these questions before implementing planned changes wherever possible.

Submitting a timely SMS notification does not necessarily make the underlying arrangement compliant.

 

9. Check right to work compliance separately

 

Sponsor reporting and right to work checks are distinct compliance obligations.

Following the right to work changes effective from 1 October 2026, employers should ensure that their procedures reflect the checking requirements applicable to relevant working arrangements, including certain worker contracts, individual subcontractors and online matching service arrangements.

Where sponsored workers are engaged through arrangements involving another organisation, the sponsor should consider its obligations under the Home Office’s Appendix D record-keeping guidance.

Right to work interaction checklist:

 

• Confirm that the worker has the necessary immigration permission for the relevant work.
• Determine whether a right to work check or follow-up check is required.
• Identify who is responsible for carrying out the applicable check.
• Retain the evidence required under the relevant rules.
• Assess whether the working arrangement creates separate sponsor reporting duties.
• Check whether the sponsor must retain evidence of checks performed by another organisation.

 

The October 2026 changes do not themselves create a new general 10 or 20 working day SMS reporting deadline.

Employers should nevertheless ensure that their compliance procedures address the interaction between the two regimes.

 

10. Retain evidence of every required notification

 

Employers should maintain records demonstrating that reportable events were identified and notifications submitted within the applicable deadlines.

These records should be sufficiently detailed to support an internal compliance review or Home Office inspection.

Evidence retention checklist:

 

• Retain documents establishing the underlying event.
• Record the reporting trigger.
• Record the calculated deadline.
• Identify the authorised user who completed the notification.
• Record the date of submission.
• Retain available SMS confirmations or submission references.
• Keep copies of supporting documents where appropriate.
• Retain relevant Home Office correspondence.
• Record any additional immigration compliance action.
• Apply the relevant Home Office record-keeping and data protection requirements.

 

The employer should be able to establish what was reported, when it was reported and why the relevant deadline applied.

 

11. Maintain a central sponsor reporting register

 

A central reporting register provides a practical method of monitoring sponsor notification obligations across the organisation.

The register should be updated whenever a potentially reportable event is identified.

It should record both completed notifications and outstanding actions.

 

Register field	Information required
Event reference	Unique internal identifier.
Worker or organisational change	Description of the event.
Reporting category	Worker, organisational or other specific requirement.
Event date	Date the change occurred.
Awareness date	Date the organisation became aware, where relevant.
Reporting trigger	Date or event starting the applicable period.
Home Office deadline	Calculated final submission date.
Responsible person	Individual accountable for completion.
Submission status	Outstanding, submitted or requiring further action.
Submission date	Date the relevant notification was completed.
Supporting evidence	Location of relevant records and confirmations.
Additional requirements	Separate immigration, licence or right to work action.

 

Employers should review the register regularly and escalate notifications approaching their deadlines.

Where a report is overdue, the register should accurately record the original deadline and subsequent corrective action.

 

12. Introduce internal reporting deadlines

 

Employers should set internal notification and escalation targets shorter than the maximum periods permitted by the Home Office.

This allows time for the immigration compliance function to assess the event, obtain supporting information and complete the relevant submission.

For example, the organisation may require line managers to notify HR or the immigration compliance team promptly when a sponsored worker resigns, changes work location or experiences an unauthorised absence.

Payroll may be required to refer proposed sponsored worker salary reductions for immigration review before implementation.

Corporate teams may be required to obtain sponsorship advice before completing mergers, acquisitions or business transfers.

Internal deadline checklist:

 

• Set a clear timeframe for escalating potentially reportable changes.
• Require advance review of planned employment changes.
• Escalate urgent or uncertain reporting events immediately.
• Use reminders for approaching Home Office deadlines.
• Allocate responsibility for monitoring outstanding reports.
• Maintain contingency arrangements for staff absence and SMS access problems.

 

Internal targets should be treated as operational safeguards, not substitutes for the Home Office reporting requirements.

 

13. Reconcile HR, payroll and SMS records regularly

 

Periodic reconciliation can help identify reportable events that have not been communicated to the sponsor licence team.

The employer should compare relevant internal records with the information held on the SMS and the central reporting register.

Checks may include:

 

• Comparing sponsored worker lists with current payroll records.
• Reviewing employment termination records against cessation-of-sponsorship notifications.
• Comparing salary changes with the information recorded for sponsored workers.
• Reviewing changes to normal work locations.
• Checking attendance records for reportable unauthorised absences.
• Reviewing recruitment records for delayed commencements.
• Comparing organisational changes with sponsor licence records.
• Checking that changes to key personnel have been addressed through the correct procedure.

 

Discrepancies should be investigated promptly.

Where an unreported event is identified, the employer should establish whether a reporting obligation arose and whether the deadline has expired.

 

14. Conduct periodic sponsor reporting audits

 

Employers should periodically review whether their sponsor reporting procedures are operating effectively.

The frequency and scope of these reviews should reflect the organisation’s size, number of sponsored workers and level of immigration compliance risk.

A sponsor reporting audit may examine:

 

• Whether reportable events are identified consistently.
• Whether reporting triggers are calculated correctly.
• Whether notifications are submitted within the applicable deadlines.
• Whether SMS submissions contain accurate information.
• Whether supporting evidence is retained.
• Whether internal escalation procedures are followed.
• Whether authorised SMS users have appropriate access.
• Whether the organisation has addressed previous reporting failures.

 

The audit should identify deficiencies and assign responsibility for corrective action.

Where significant weaknesses are identified, the employer should consider a wider sponsor licence compliance review.

 

15. Establish an escalation procedure for missed deadlines

 

Employers should have a documented procedure for responding when a mandatory reporting deadline has been missed or may be at risk of being missed.

The procedure should require prompt assessment and appropriate senior oversight.

Missed deadline escalation checklist:

 

1. Confirm the reportable event and applicable Home Office requirement.
2. Establish the original reporting trigger and deadline.
3. Determine whether the notification remains outstanding.
4. Submit or correct the report through the appropriate procedure where possible.
5. Retain an accurate record of the delay.
6. Assess whether the underlying event creates additional immigration compliance risks.
7. Escalate material concerns to the Authorising Officer.
8. Investigate the cause of the failure.
9. Check whether similar omissions have occurred.
10. Implement appropriate corrective measures.

 

Where the circumstances involve a material immigration breach, corporate transaction or potential Home Office enforcement action, specialist legal advice may be appropriate.

 

16. Provide sponsor reporting training to relevant staff

 

Sponsor reporting training should extend beyond individuals authorised to use the SMS.

Many reportable events arise in departments that do not administer the sponsor licence directly.

HR, payroll, recruitment, line management and corporate personnel should understand which developments must be escalated for immigration compliance review.

Training should cover:

 

• Common sponsored worker reporting triggers.
• The distinction between 10 and 20 working day reporting requirements.
• Specific rules for unauthorised absence and delayed commencement.
• Changes to salary, duties and work location.
• Organisational changes and corporate transactions.
• Internal escalation requirements.
• The importance of accurate dates and supporting records.
• The consequences of missed reporting deadlines.

 

Training should be refreshed when relevant Home Office guidance changes or when an internal audit identifies weaknesses in the organisation’s reporting arrangements.

 

17. Review reporting procedures after business or regulatory changes

 

Sponsor reporting procedures should be reviewed when the organisation undergoes material business changes or when the Home Office updates its requirements.

Events that may justify a review include:

 

• A merger or acquisition.
• A significant increase in the sponsored workforce.
• Expansion into new business locations.
• Changes to HR or payroll systems.
• Changes to sponsor licence key personnel.
• Changes to authorised SMS user arrangements.
• Introduction of new working or engagement models.
• Relevant changes to Home Office sponsor guidance.

 

Employers should ensure that reporting procedures remain aligned with their actual operations.

A process designed for a small number of sponsored workers may no longer be adequate after substantial workforce growth or corporate restructuring.

 

18. Sponsor reporting deadlines: final employer control checklist

 

The following summary can be used as a final control before a sponsor reporting matter is closed.

 

Control question	Required confirmation
Has the change been identified?	The relevant event and affected worker or organisation are recorded.
Has reportability been assessed?	The applicable Home Office requirement or exception has been identified.
Has the correct trigger been established?	The event, effective or awareness date has been assessed as required.
Has the deadline been calculated?	The correct working day period and applicable exclusions have been applied.
Has responsibility been allocated?	An authorised individual is responsible for the required action.
Has the correct procedure been identified?	The appropriate SMS function or alternative Home Office process is confirmed.
Has the notification been submitted?	The submission date and available confirmation are recorded.
Have supporting records been retained?	Evidence of the event, calculation and submission is available.
Have additional immigration requirements been assessed?	Any separate worker, licence or right to work obligations have been addressed.
Have outstanding actions been completed?	Any Home Office requests or corrective measures have been followed up.

 

A reporting matter should not be treated as complete merely because the SMS notification has been submitted.

The employer should also confirm that any related immigration requirements have been addressed and that the relevant records are accurate.

Employer compliance point: Sponsor reporting deadlines are best managed through an integrated compliance process rather than individual reminders. Employers should combine early identification of reportable events, accurate deadline calculation, authorised SMS access, reliable evidence retention and periodic review to reduce the risk of late notifications and wider sponsor licence enforcement action.

Section K: Sponsor Licence Reporting Deadlines: Frequently Asked Questions

 

What is the deadline for reporting sponsor licence changes?

The deadline depends on the type of change being reported. Many changes affecting sponsored workers must be reported within 10 working days, while many changes affecting the sponsoring organisation are subject to a 20 working day reporting requirement.

However, the Home Office applies specific rules to certain events, including unauthorised absence, delayed employment commencement, changes to sponsor licence key personnel and corporate transactions.

Employers should identify the precise reporting requirement and trigger rather than assuming that every worker or organisational change follows the same deadline.

 

What is the 10 working day rule for sponsor licences?

The 10 working day rule generally requires licensed sponsors to report specified changes affecting sponsored workers within the relevant reporting period.

Reportable events can include a worker ceasing sponsored employment, certain changes to salary or work location and other circumstances specified in the Home Office sponsor guidance.

The deadline does not always begin on the same type of date. Some events have specific triggers or thresholds.

For example, the unauthorised absence reporting requirement is calculated by reference to the tenth consecutive working day of absence, while delayed commencement involves a separate permitted commencement period.

 

What is the 20 working day rule for sponsor licences?

The 20 working day rule generally applies to specified changes affecting the sponsoring organisation.

These can include changes to business details, relevant addresses, business activities and corporate arrangements.

For many organisational changes, the general reporting period runs from when the sponsoring organisation becomes aware of the change.

However, specific exceptions apply, including requirements concerning certain key personnel changes and corporate transactions.

A merger, acquisition or business transfer may also require a new sponsor licence application rather than merely an SMS notification.

 

Do weekends count towards sponsor licence reporting deadlines?

Weekends are generally excluded when calculating sponsor reporting periods expressed in working days under the applicable Home Office guidance.

Employers must also account for relevant public holidays in accordance with the definition of a working day contained in the applicable rules.

However, weekends are not automatically excluded from periods expressed in calendar days.

This distinction is important for delayed commencement, where the initial permitted period is expressed in days and the subsequent notification period is expressed in working days.

 

Do bank holidays count towards the 10 and 20 working day deadlines?

Relevant public holidays are excluded where required by the applicable Home Office definition of a working day.

Employers should consult the current sponsor guidance and the official bank holiday calendar when calculating a deadline.

They should not assume that every local or regional holiday automatically extends the reporting period.

An employer’s own office closure days also do not necessarily extend a Home Office deadline.

 

When does the 10 working day reporting deadline start?

The starting point depends on the event being reported.

For many worker-related changes, the reporting period is linked to the relevant event occurring or taking effect.

However, specific Home Office provisions govern events such as unauthorised absence and failure to commence sponsored employment.

The date on which the immigration compliance team discovers a change does not automatically become the reporting trigger.

Employers should record the event date, effective date and any other relevant trigger before calculating the deadline.

 

When does the 20 working day reporting deadline start?

For many organisational changes, the general Home Office requirement is to report within 20 working days of the sponsoring organisation becoming aware of the change.

However, employers must check whether a specific provision applies to the particular event.

For example, changes to certain sponsor licence key personnel and corporate transactions may involve different requirements.

The employer should not assume that the period begins only when a Level 1 User receives the information if the organisation was already aware of the change.

 

How long does an employer have to report a sponsored worker leaving?

Where a sponsored worker ceases employment or the employer stops sponsoring them, the sponsor must generally report the relevant cessation within 10 working days of the applicable trigger.

The employer should establish the worker’s actual final employment date and follow the relevant Home Office reporting procedure.

The notification is generally submitted through the Sponsor Management System using the appropriate worker reporting function.

Employers should retain evidence of the termination, the reporting deadline and the completed notification.

 

When must a sponsor report unauthorised absence?

Where a sponsored worker is absent from work without permission for more than 10 consecutive working days, the sponsor must report the absence no later than 10 working days after the tenth day of absence.

The employer should establish the relevant absence dates and maintain records of attempts to contact the worker.

The notification should contain the information required by the Home Office guidance, including relevant details of the absence and whether sponsorship will continue.

If the absence results in employment ending, the employer should also assess the separate cessation-of-sponsorship reporting obligation.

 

When must an employer report a sponsored worker who has not started work?

The Home Office applies specific rules where a sponsored worker does not commence employment within the applicable permitted period.

Under the general provisions, the employer must assess whether the worker has started within the relevant 28-day period.

Where the worker has not commenced and the reporting obligation applies, the sponsor must generally notify the Home Office by the end of 10 working days following that period.

The date from which the initial 28-day period is calculated depends on the applicable Home Office rules and the worker’s circumstances.

Employers should also assess whether they are permitted to continue sponsoring the worker.

 

Does a sponsor have to report a salary increase?

Ordinary salary increases generally do not need to be reported through the SMS, subject to specific exceptions.

One relevant exception concerns certain sponsored nurses and midwives whose salary changes following professional registration.

Employers should check the applicable Home Office guidance before concluding that a salary change is not reportable.

Salary reductions require particular care because they may be reportable and may affect the worker’s continued eligibility under the Immigration Rules.

 

Does a sponsor have to report a salary reduction?

Certain reductions in a sponsored worker’s salary must be reported to the Home Office.

The employer should assess the reason for the reduction, the applicable reporting provisions and whether any exception applies.

It must also consider whether the revised salary continues to satisfy the requirements of the worker’s immigration route.

Reporting a salary reduction does not automatically make the reduction permissible.

Where the change causes the worker to fall below the applicable salary requirements, the employer may face a substantive sponsorship compliance issue in addition to any reporting obligation.

 

Does changing a sponsored worker’s work location need to be reported?

Certain changes to a sponsored worker’s normal work location must be reported to the Home Office.

Employers should distinguish between a reportable change to the worker’s normal work location and temporary arrangements that do not meet the relevant reporting criteria.

Hybrid working and homeworking arrangements should be assessed against the current sponsor guidance.

The employer should establish whether the change is reportable, identify the applicable trigger and submit any required notification within the relevant deadline.

 

Do employers need to report a change of business address?

Relevant changes to a sponsoring organisation’s business address may require notification to the Home Office.

The employer should establish whether the change concerns its registered office, trading address, relevant business premises or another address recorded against the sponsor licence.

Many organisational changes fall within the general 20 working day reporting framework, although the applicable provision must be checked.

The employer should use the correct SMS licence change procedure and provide any supporting information required by the Home Office.

 

Do sponsor licence key personnel changes have to be reported within 20 working days?

Changes to sponsor licence key personnel are subject to specific Home Office requirements.

Employers should not assume that every change to an Authorising Officer, Key Contact or authorised SMS user follows the general organisational reporting deadline.

Where the Authorising Officer or Key Contact is replaced, the sponsor must follow the particular notification and appointment provisions.

Changes affecting Level 1 Users should also be managed through the appropriate Home Office user-management procedure.

The employer should ensure that its key personnel arrangements remain compliant throughout the change.

 

Does a merger or acquisition need to be reported within 20 working days?

Mergers, acquisitions and other corporate transactions can create sponsor reporting obligations and may also require a new sponsor licence application.

In specified circumstances, the Home Office requires a new sponsor licence application within 20 working days of the relevant corporate change.

The obligations depend on the legal entities involved, the nature of the transaction and the position of any sponsored workers transferring between organisations.

Employers should obtain immigration advice before completing transactions affecting a licensed sponsor.

A notification through the SMS does not necessarily replace a required new sponsor licence application.

 

How does an employer report sponsor licence changes to the Home Office?

Most routine sponsor notifications are submitted through the Home Office Sponsor Management System.

Many worker-related changes are reported using the relevant Report migrant activity function.

Organisational changes may require the Request changes to licence details function or another prescribed procedure.

The notification must be completed by an appropriately authorised user with the necessary permissions.

Some changes require supporting documents, Home Office approval or a separate sponsor licence application.

Employers should retain evidence of the submission and monitor any outstanding Home Office requests.

 

What happens if a sponsor misses the 10 working day reporting deadline?

Missing a mandatory 10 working day reporting deadline can constitute a breach of sponsor duties.

The consequences depend on the nature of the event, the seriousness of the failure and the applicable Home Office enforcement provisions.

A late notification does not automatically result in sponsor licence revocation.

However, reporting failures may contribute to compliance investigations, licence downgrading, suspension or revocation, particularly where they form part of wider or repeated non-compliance.

The employer should establish the original deadline, complete the outstanding notification through the appropriate procedure where possible and assess whether the underlying change creates additional immigration compliance risks.

 

Is there a fine for submitting a sponsor licence report late?

There is no general fixed financial penalty imposed solely because a sponsor submits an SMS notification after the applicable deadline.

The principal consequences arise under the Home Office’s sponsor compliance and enforcement framework.

However, the underlying circumstances may involve separate breaches carrying financial penalties.

For example, illegal working can result in a civil penalty of up to £60,000 per illegal worker under the applicable regime.

Employers should distinguish the reporting breach from any separate right to work or immigration compliance failure.

 

Can an employer correct a late sponsor licence report?

Where a sponsor discovers that a mandatory notification has been missed, it should establish the correct reporting requirement and identify the appropriate procedure for submitting the outstanding information.

In many cases, a late report may still be submitted through the relevant SMS function, although the available procedure depends on the circumstances.

The employer should retain evidence of the original event, the missed deadline and the corrective action taken.

It should also investigate why the report was missed and whether similar failures have occurred.

Submitting a late notification does not automatically remove the original breach or prevent Home Office enforcement action.

Where the underlying event affects the validity of sponsorship, the worker’s immigration eligibility or a corporate licence requirement, specialist immigration advice may be necessary.

 

Back to top

 

Section L: Sponsor Licence Reporting Deadlines: Conclusion

 

Sponsor licence reporting deadlines are a fundamental part of an employer’s ongoing compliance obligations. Licensed sponsors must identify reportable changes, apply the correct Home Office reporting period and submit accurate notifications through the appropriate procedure.

The general distinction between 10 working day deadlines for many sponsored worker changes and 20 working day deadlines for many organisational changes provides a useful starting point. However, employers must account for event-specific reporting triggers, exceptions and additional requirements.

Unauthorised absence, delayed employment commencement, changes to key personnel and corporate transactions can involve particular rules. Some changes also require a separate immigration application, sponsor licence request or new licence application.

Missing a reporting deadline can constitute a breach of sponsor duties and may expose the organisation to Home Office compliance action. Depending on the circumstances, this can include licence downgrading, suspension or revocation.

Employers should therefore maintain effective internal controls for monitoring sponsored workers, identifying organisational changes, calculating deadlines and retaining evidence of completed notifications.

Where a deadline has already been missed, the organisation should establish the original reporting requirement, address the outstanding notification where possible and assess whether the underlying circumstances create wider immigration compliance risks.

Section M: Glossary: Sponsor Licence Reporting Deadlines

 

The following glossary explains the principal terms used in relation to sponsor licence reporting deadlines, Home Office notifications and employer sponsorship compliance.

 

Term	Meaning
Sponsor Licence	A sponsor licence is the authorisation granted by the Home Office allowing an eligible organisation to sponsor overseas workers under specified UK immigration routes. Licensed sponsors must comply with ongoing duties, including reporting relevant changes affecting sponsored workers and the sponsoring organisation.
Sponsor Reporting Duties	Sponsor reporting duties are the obligations requiring licensed sponsors to notify the Home Office of specified changes or events. These include certain developments affecting sponsored workers, employment arrangements, business details and organisational circumstances.
Sponsor Licence Reporting Deadline	A sponsor licence reporting deadline is the period within which a licensed sponsor must notify the Home Office of a specified event. Many worker-related changes are subject to a 10 working day requirement, while many organisational changes are subject to a 20 working day requirement. Specific exceptions and alternative triggers apply.
10 Working Day Reporting Rule	The 10 working day reporting rule is the general requirement applicable to many reportable changes affecting sponsored workers. The precise starting point depends on the event and the applicable Home Office sponsor guidance.
20 Working Day Reporting Rule	The 20 working day reporting rule generally applies to specified changes affecting a sponsoring organisation. For many organisational changes, the reporting period runs from when the sponsor becomes aware of the change. Specific requirements apply to certain key personnel changes and corporate transactions.
Working Day	A working day is a day counted for the purposes of a deadline expressed in working days under the applicable Home Office rules. Saturdays, Sundays and relevant public holidays are generally excluded. Employers should use the definition contained in the applicable guidance when calculating reporting deadlines.
Calendar Day	A calendar day is a day counted without automatically excluding weekends or public holidays. The distinction between calendar days and working days is important when calculating the permitted commencement period for sponsored employment and the subsequent reporting deadline.
Reporting Trigger	A reporting trigger is the event, date or circumstance that starts the applicable Home Office notification period. Depending on the reporting requirement, the trigger may be linked to an event occurring, a change taking effect, the sponsor becoming aware of a change or a specified threshold being reached.
Reportable Event	A reportable event is a change or occurrence that a licensed sponsor is required to notify to the Home Office under the applicable sponsorship rules. Not every employment or organisational change is reportable, and employers must assess the relevant requirements and exceptions.
Sponsor Management System (SMS)	The Sponsor Management System is the Home Office’s online platform used by licensed sponsors to administer sponsorship activities. It provides functions for managing Certificates of Sponsorship, submitting specified worker notifications, requesting licence changes and managing authorised users.
Report Migrant Activity	Report migrant activity is an SMS function used to submit specified notifications concerning sponsored workers. Depending on the circumstances, these may include relevant changes to employment, unauthorised absence, non-commencement or cessation of sponsorship.
Request Changes to Licence Details	Request changes to licence details is an SMS function used for certain requests and notifications concerning the sponsoring organisation. The appropriate procedure depends on the nature of the change, and some requests require supporting documents or Home Office approval.
Certificate of Sponsorship (CoS)	A Certificate of Sponsorship is an electronic sponsorship record assigned by a licensed sponsor to a worker for a relevant immigration application. It contains information about the sponsored role and employment arrangements. Changes affecting those arrangements may create reporting or additional immigration requirements.
Authorising Officer	The Authorising Officer is the senior individual responsible for appropriate oversight of the organisation’s sponsorship activities and compliance with sponsor duties. The role includes responsibility for ensuring that effective arrangements exist for managing the sponsor licence, although routine SMS reporting may be undertaken by authorised users.
Key Contact	The Key Contact is the individual designated as a principal point of contact between the sponsoring organisation and the Home Office in relation to its sponsor licence. Changes affecting the Key Contact are subject to the applicable Home Office notification and appointment requirements.
Level 1 User	A Level 1 User is an individual authorised to perform specified sponsor administration functions through the SMS. Depending on their permissions, these can include reporting changes, managing sponsorship records and requesting amendments to licence details.
Level 2 User	A Level 2 User is a category of SMS user with more limited permissions than a Level 1 User. The Home Office introduced restrictions on adding new Level 2 Users from 9 September 2026, with the role scheduled to be removed after 8 March 2027.
Multi-Factor Authentication (MFA)	Multi-factor authentication is a security process requiring an SMS user to complete an additional verification step when accessing the system. Mandatory MFA was introduced for SMS users from 3 September 2026. Employers should maintain appropriate access arrangements to avoid disruption to time-sensitive reporting.
Unauthorised Absence	Unauthorised absence occurs where a sponsored worker is absent from work without the employer’s permission. Where the absence exceeds 10 consecutive working days, the sponsor must comply with the relevant Home Office reporting requirement, including the prescribed notification deadline.
Delayed Commencement	Delayed commencement occurs where a sponsored worker does not start employment within the period permitted under the applicable Home Office rules. The sponsor must assess the relevant 28-day commencement provisions, whether continued sponsorship is permitted and whether a notification must be submitted.
Cessation of Sponsorship	Cessation of sponsorship occurs when an employer stops sponsoring a worker, including where the worker leaves employment or the sponsorship relationship otherwise ends. The sponsor must report relevant cessation events within the applicable Home Office deadline.
Change of Employment	A change of employment is a change to a sponsored worker’s employment circumstances that may require a new immigration application under the applicable Immigration Rules. Some employment changes also create sponsor reporting obligations. An SMS notification does not replace a required change of employment application.
Change of Work Location	A change of work location is a change affecting where a sponsored worker normally undertakes their employment duties. Certain changes must be reported to the Home Office, while temporary arrangements may be treated differently under the applicable guidance.
Sponsor Licence Key Personnel	Sponsor licence key personnel are individuals appointed to fulfil specified roles in the organisation’s sponsorship arrangements, including the Authorising Officer, Key Contact and Level 1 User. Changes to these appointments must be managed in accordance with the applicable Home Office requirements.
Corporate Change	A corporate change is a development affecting the structure, ownership, legal identity or operations of a sponsoring organisation. Examples include mergers, acquisitions, business transfers, restructuring and certain insolvency events. Such changes may create reporting obligations and, in specified circumstances, require a new sponsor licence application.
TUPE Transfer	A TUPE transfer is a transfer of employment falling within the Transfer of Undertakings (Protection of Employment) Regulations. Where sponsored workers are affected, the organisations involved must assess the sponsor licence and immigration consequences, including applicable reporting requirements and whether a new sponsor licence application is necessary.
Sponsor Compliance Visit	A sponsor compliance visit is a Home Office inspection or assessment of whether an organisation is meeting its sponsorship obligations. The Home Office may examine worker records, payroll information, attendance monitoring, SMS notifications and internal procedures for identifying and reporting changes.
Sponsor Licence Downgrading	Sponsor licence downgrading occurs where the Home Office changes a sponsor’s rating from A to B under the applicable enforcement framework. A B-rated sponsor may be subject to restrictions and required to complete an action plan addressing identified compliance deficiencies.
Sponsor Licence Suspension	Sponsor licence suspension is an enforcement measure under which the Home Office temporarily suspends the organisation’s sponsorship authorisation while relevant concerns are considered. While the licence is suspended, the sponsor cannot assign any Certificates of Sponsorship. Suspension may lead to further action, including revocation.
Sponsor Licence Revocation	Sponsor licence revocation is the withdrawal of an organisation’s authority to sponsor workers under the affected licence. Revocation can have significant consequences for the employer and its sponsored workforce. The Home Office guidance identifies circumstances in which it will, will normally or may revoke a sponsor licence.
