If you sponsor workers on the Skilled Worker visa, payroll compliance has never required more attention than it does right now. From April 2026, the Home Office has introduced updated guidance on how pay periods are assessed during compliance checks and visa applications. Errors that might once have been treated as minor administrative oversights are now being treated as material breaches. If your payroll records do not line up with what you stated on a Certificate of Sponsorship, you are exposed.
This is not a theoretical risk. The number of sponsor licences being reviewed, suspended, or revoked has increased consistently. Getting clear on your obligations now, with the support of experienced sponsor licence solicitors, is far less costly than dealing with a compliance investigation after the fact.
What the Updated Pay Period Rules Actually Mean
The core issue is how the Home Office expects pay to be evidenced and calculated across different pay frequencies. Many employers pay workers weekly, fortnightly, or four-weekly rather than on a calendar monthly basis. Under the previous guidance, there was a degree of flexibility in how annualised salaries were calculated from these pay cycles. That flexibility has been tightened.
From April 2026, the Home Office expects sponsors to be able to demonstrate, from payroll records, that the worker has been paid in a way that consistently meets or exceeds the salary stated on their Certificate of Sponsorship when annualised correctly. If there are gaps, short payments in any pay period, or discrepancies between what is on the CoS and what payslips show, these will be flagged.
It is worth reading the detailed breakdown of the skilled worker visa salary threshold changes in 2026 to understand the current thresholds alongside these updated payroll rules.
Which Pay Frequencies Are Affected
The updated guidance applies across all pay frequencies, but some are more prone to compliance issues than others.
| Pay Frequency | Periods Per Year | Annualisation Method | Common Error |
|---|---|---|---|
| Weekly | 52 | Multiply weekly pay by 52 | Short weeks or unpaid weeks pulling down the annual total |
| Fortnightly | 26 | Multiply fortnightly pay by 26 | Rounding errors reducing annualised figure below threshold |
| Four-weekly | 13 | Multiply four-weekly pay by 13 | Confusion with monthly pay, leading to underpayment in 13th period |
| Calendar monthly | 12 | Multiply monthly pay by 12 | Deductions in any month not being reported as required |
| Bi-monthly | 24 | Multiply bi-monthly pay by 24 | Inconsistent pay amounts not reconciling with CoS figure |
The four-weekly frequency is particularly worth flagging. There are 13 four-weekly periods in a year, not 12. Employers who calculate their annual pay obligation by multiplying the four-weekly figure by 12 will be paying their workers less than the threshold requires, and this is a compliance failure.
Why This Matters More Than It Did Before
The Home Office already expects sponsors to meet the full skilled worker immigration uk requirements throughout the duration of a worker’s employment, not just at the point of application. What has changed is the level of scrutiny being applied to how that is evidenced.
During compliance visits and pre-application checks, caseworkers are now looking more closely at actual payslips rather than simply confirming the headline salary on the Certificate of Sponsorship. If a worker has had any period of unpaid leave, reduced hours, or deductions that were not reported to the Home Office, this can suggest a systemic failure in your compliance approach, even if the underlying salary is technically correct.
Our detailed guide to managing unpaid leave for sponsored workers covers the specific rules around when unpaid leave must be reported and how it should be handled on your payroll without breaching your obligations.
The Link Between Payroll Compliance and Sponsor Reporting Duties
Your payroll records sit at the heart of your sponsor reporting obligations. There are specific events that you are required to report to the Home Office via the Sponsor Management System, and many of them are directly connected to pay.
These include:
- Significant changes to a worker’s salary, whether up or down
- Moving a worker to unpaid leave or reduced hours for any reason
- Changes to a worker’s working pattern that affect their overall remuneration
- Deductions from pay that bring a worker below their CoS salary in a given period
The guide to business changes that trigger sponsor reporting is a useful reference for understanding the full scope of what must be reported and within what timeframes.
Failing to report these changes is itself a compliance breach, separate from any underlying payroll issue. The Home Office takes the view that if you did not report something, you either did not know about it, which suggests your systems are inadequate, or you knew and chose not to report it, which is more serious still.
What Good Payroll Records Look Like
If the Home Office visited your premises tomorrow, your payroll records should be able to demonstrate, clearly and without ambiguity, that each sponsored worker has been paid the correct amount in every pay period since they joined you.
In practice, this means:
- Payslips are available for every pay period since sponsorship began
- The gross pay figure on each payslip can be reconciled to the CoS salary when annualised correctly
- Any deductions are clearly itemised and explained
- Any periods of unpaid leave are accompanied by a record of the report you made to the Home Office
- The payroll frequency has remained consistent, or any change was reported
- National Insurance contributions are consistent with the pay stated, which is one way the Home Office cross-checks figures
Your key personnel on your sponsor licence are responsible for ensuring these records exist and are accessible. The Authorising Officer in particular carries personal responsibility for your compliance posture.
How Compliance Visits Assess Payroll
A Home Office compliance visit can happen at any time and without prior notice. During a visit, inspectors will typically ask to see payroll records for a sample of your sponsored workers. They will compare what those records show with the information on the relevant Certificates of Sponsorship.
For a full picture of what happens during these visits and how to prepare, the guide to sponsor licence compliance visits is essential reading. One of the most common findings during compliance visits is a mismatch between the pay frequency on payroll records and what was expected based on the CoS, particularly where a four-weekly payroll has been confused with a monthly one.
What Happens If a Compliance Issue Is Found
If the Home Office finds a payroll compliance issue during a visit or as part of a review, the consequences can escalate quickly. The typical progression is:
- A formal notice of intention to suspend or downgrade your licence
- A period in which you can submit a response explaining and evidencing how you are addressing the issue
- A decision to either restore your licence, keep a downgraded rating, or proceed to suspension or revocation
If your licence is sponsor licence suspended, you cannot assign new Certificates of Sponsorship during the suspension period, and the Home Office may also consider the status of the workers you currently sponsor. A revocation is significantly more serious and has consequences for every worker you sponsor.
Getting sponsor licence solicitors involved as early as possible in this process gives you the best chance of putting together a credible response. The window for doing so is usually short.
Common Payroll Mistakes Sponsors Make
Across the kinds of cases our team at Garth Coates Solicitors sees regularly, certain payroll errors come up repeatedly. Being aware of these is the first step to avoiding them.
- Calculating annual pay from a four-weekly figure multiplied by 12 instead of 13
- Applying salary sacrifice schemes in a way that reduces gross pay below the threshold
- Failing to increase pay when the Home Office threshold is raised, where the worker is relying on a going rate that has changed
- Deducting amounts for accommodation or transport that bring gross pay below what was stated on the CoS
- Not reporting a shift from full-time to part-time hours promptly
- Overlooking the requirement to report an absence that extends beyond 4 weeks
- Using incorrect annualisation for workers whose hours vary week to week
It is also worth being aware of the rules around the immigration salary list, particularly if you sponsor workers in roles where the going rate is below the general threshold. These workers still need to be paid at least the going rate for their occupation code, and that rate must be evidenced through payroll in exactly the same way.
Payroll Compliance for Self-Sponsoring Directors
If you came to the UK through a self sponsorship visa solicitor arrangement and are now the director of your own sponsoring company, the payroll rules apply to you in the same way they apply to any other sponsored worker. You cannot pay yourself below the threshold stated on your own Certificate of Sponsorship, and your company payroll records need to show this clearly.
The Home Office is aware that self-sponsoring directors can, in theory, manipulate their own pay records. This means scrutiny of payroll compliance for self-sponsoring arrangements is, if anything, slightly higher than for conventional employment relationships.
Expansion Workers and Payroll Compliance
If you have workers in the UK under the uk expansion worker visa route, the payroll compliance picture is slightly different because expansion workers are paid by their overseas parent company, not the UK entity. However, you still need to be able to show that the worker’s remuneration is consistent with what was stated in their application, and that the UK entity is genuinely operating rather than simply being used as a visa vehicle.
Payroll Compliance and the Route to Settlement
For sponsored workers planning to apply for Indefinite Leave to Remain, their payroll history over the five-year qualifying period will be relevant. Any periods where pay fell below the required level can cause complications. The full picture of how this works is covered in the guide to ILR settlement for skilled workers.
For workers who have completed their settlement journey and are thinking about applying for naturalisation, working with experienced british citizenship solicitors ensures their immigration history, including their employment record, is presented in the strongest possible way.
Practical Steps to Take Right Now
If you are a sponsor, here is what we recommend doing before the next pay run.
- Review which pay frequency you are using for each sponsored worker and confirm it is being annualised correctly
- Pull payslips for the last 12 months for each sponsored worker and check gross pay in every period
- Confirm that no deductions have been applied that reduce gross pay below the CoS figure
- Check whether any absences or changes in hours occurred that should have been reported but were not
- Review whether any going rates for the occupation codes you use have been updated and whether pay needs to be adjusted
If you are unsure whether a specific situation needs to be reported to the Home Office, the sponsor duties and compliance guide covers the key obligations in plain terms.
Frequently Asked Questions
Does the four-weekly pay rule apply from April 2026 or has it always been this way?
The underlying obligation to annualise pay correctly has always existed. What has changed is that the Home Office is now applying more structured scrutiny to this in compliance checks and processing, making it more likely that errors will be identified and acted upon.
Can salary sacrifice arrangements be used for sponsored workers?
Yes, but the gross pay before salary sacrifice must meet the threshold. If a salary sacrifice scheme reduces the worker’s gross pay below what was stated on their Certificate of Sponsorship, this is a compliance breach.
What if we accidentally underpaid a sponsored worker for one month?
You should seek advice promptly. Depending on the circumstances, you may need to make good the underpayment and report the issue to the Home Office. Acting quickly and transparently is far better than hoping it goes unnoticed during a compliance visit.
Does the Home Office check payroll records when processing a visa renewal?
Caseworkers can and do request payroll evidence as part of the processing of extension or renewal applications. If what is submitted does not match the original CoS, this can cause delays or refusals.
What if a sponsored worker switches to part-time hours at their own request?
The worker can only reduce their hours if the resulting pay still meets the required threshold. If it does not, you cannot accommodate the request without either increasing their hourly rate or seeking specialist advice on the options available.
How long do I need to keep payroll records for sponsored workers?
The Home Office expects records to be retained for at least one year after the sponsored worker’s employment ends. In practice, keeping them for longer is sensible in case of any late compliance review.
