Sponsor licence compliance in 2026 now turns on one thing many sponsors overlook: your payroll. UK Visas and Immigration (UKVI) matches the salary on each Certificate of Sponsorship against real HMRC pay data. When those figures do not align, your licence is at risk.
This article explains why payroll became the main audit trigger and what you should check today. It also sets out the new pay period rule that many sponsors have missed.
What Sponsor Licence Compliance Now Requires
Sponsor licence compliance means meeting every duty the Home Office sets while you hold your licence. These duties cover record keeping, reporting changes, and paying your sponsored workers at the correct rate. Your sponsor duties continue for as long as you sponsor any worker.
The rules changed in March 2026, when the Home Office updated all three parts of its sponsor guidance. The update formalised how UKVI checks pay, and it tightened what now counts as a breach. The Home Office now judges you on continuous sponsor licence compliance, not a single annual snapshot.
Why UKVI Is Watching Your Payroll
UKVI now finds most breaches through data, not site visits. It compares the pay you report on each Certificate of Sponsorship against the figures HMRC holds. The scale of recent enforcement shows why this matters:
- The Home Office revoked around 3,100 sponsor licences in 2025. That was the highest annual total since the sponsorship system began in 2012.
- More than 1,500 of those revocations came between October and December 2025.
- Compliance visits rose 51% during the year. UKVI audits now reach businesses of every size, in every sector, including those never visited before.
- The Home Office shares data with HMRC and Companies House to flag pay mismatches. It can act on a single discrepancy without ever setting foot on your premises.
- Employing anyone without the right to work risks a civil penalty of £45,000. The penalty rises to £60,000 for repeat breaches.
The Salary Rule Most Sponsors Miss
The salary rule most sponsors miss is simple. You must pay each sponsored worker enough in every pay period, not just on average across a year. Under new rule SW 14.3B, this applies to any Certificate of Sponsorship assigned on or after 8 April 2026.
The general threshold for a Skilled Worker visa is £41,700 a year, or the higher going rate. The hourly floor is £21.38 for most roles, and bonuses cannot lift a low base salary over it. The Official GOV.UK sponsor duties guidance confirms the Home Office checks your pay against each Certificate of Sponsorship.
Common Payroll Mistakes Putting Your Licence at Risk
Many businesses lose their sponsorship status due to preventable payroll calculation errors. For example, a UK company recently lost its status after misclassifying sponsored staff roles on payroll. Failing to track small adjustments often results in a swift sponsor licence suspension. These payroll errors can directly lead to a breach of your sponsor licence compliance.
Unpaid leave deductions
Taking unpaid leave can accidentally push a worker below the required salary threshold. You must report any unpaid leave lasting more than four weeks via the sponsor portal. Dropping below the £41,700 threshold during a single month violates current compliance rules.
Salary sacrifice schemes
Enrolling sponsored staff in pension salary sacrifice schemes reduces their gross reportable pay. The Home Office calculates compliance using the gross salary after these benefit sacrifices. You cannot use these schemes if they lower the base salary below the legal minimum.
Bonus heavy pay structures
Relying on seasonal bonuses to meet salary thresholds is a dangerous strategy for employers. The new pay period rules require steady guaranteed pay across every single month. You must restructure compensation packages to guarantee the minimum baseline salary.
What happens if you underpay a sponsored worker?
You risk a sponsor licence suspension or revocation. The Home Office treats underpayment below the Certificate of Sponsorship salary as a breach of your duties.
What sponsors should check now
You can reduce your risk by checking your payroll against your sponsorship records now. A short review often catches problems before the Home Office does. With over 1,500 revocations occurring in late 2025 alone, proactive internal checks are now vital.
- Compare each worker's actual pay with the salary recorded on their Certificate of Sponsorship. Check the figure in every pay period, not the annual average.
- Confirm that base pay alone meets the threshold and the going rate for the role. Bonuses and overtime do not count.
- Check that you have reported any reduced pay, unpaid leave, or role change on time. Late reports are a frequent cause of action.
- Book a sponsor licence compliance audit if you are unsure where you stand. An independent review can find and fix gaps before UKVI ever contacts you.
Does UKVI check HMRC data?
Yes, official Home Office guidance confirms that automated systems cross-reference your records monthly.
Can I fix underpayments later?
No, retrospective payments cannot correct a past compliance breach.
What triggers a payroll audit?
Salary mismatches on tax submissions trigger instant automated reviews.
