UK Sponsor Licence Compliance in 2026: Duties, HMRC Payroll Checks, and the Rising Risk of Revocation

Holding a UK sponsor licence has never been more difficult than it is in 2026. The Home Office revoked approximately 3,000 sponsor licences in 2025, nearly triple the 1,100 revocations recorded in 2024. Compliance visits have increased by over 50%. And from April 2026, UK Visas and Immigration (UKVI) will gain systematic access to HMRC payroll data, enabling real-time detection of salary discrepancies for every sponsored worker in the country. For employers, the margin for error has become extremely thin.

This article explains what sponsor licence holders must do to remain compliant, how the new HMRC data-sharing regime works, what happens during a compliance visit, and what to do if your licence is suspended or revoked.

What Is a Sponsor Licence?

A sponsor licence is the permission granted by the Home Office to a UK employer to recruit workers from outside the UK under the points-based immigration system. It is required for the Skilled Worker route, the Senior or Specialist Worker route under the Global Business Mobility category, and several other visa routes. The licence is not a one-off application. It creates ongoing obligations that the employer must meet for the entire duration of the licence, typically four years before renewal.

Employers apply for a sponsor licence through the Sponsor Management System (SMS), an online portal through which they also issue Certificates of Sponsorship (CoS), report changes in sponsored workers' circumstances, and manage their compliance record. The SMS is the central hub of the sponsor-worker relationship, and the Home Office monitors it continuously.

Core Sponsor Duties

The Home Office Sponsor Guidance, updated most recently on 6 March 2026, organises sponsor duties into five broad categories. Record-keeping duties require employers to maintain copies of each sponsored worker's passport, biometric residence permit, evidence of qualifications, employment contract, and payslips. These records must be available for inspection at any time. Reporting duties require employers to notify the Home Office via the SMS within 10 working days of specified events: if a sponsored worker fails to start their job, stops attending work for 10 consecutive working days without permission, changes their job title or duties, has their salary reduced, moves to a different work location, or leaves the organisation. Compliance duties require the employer to ensure that sponsored workers are genuinely employed in the role described on their Certificate of Sponsorship, at or above the stated salary, and that the employer's HR systems are robust enough to detect and prevent illegal working.

Cooperation duties require employers to allow Home Office officials access to their premises for compliance visits at reasonable times, and to provide documents and information promptly when requested. Finally, there are general duties related to maintaining a genuine business, not engaging in behaviour that is not conducive to the public good, and informing the Home Office of any changes to the organisation's circumstances, such as a change of ownership, merger, or insolvency.

The HMRC Payroll Data-Sharing Regime

The most significant change for 2026 is the introduction of systematic HMRC payroll data-sharing with the Home Office, effective from April 2026. Under this regime, the Home Office will receive access to Real Time Information (RTI) payroll data submitted by employers to HMRC through the PAYE system. This data includes the salary paid to each employee in each pay period, hours worked, tax deducted, and National Insurance contributions.

For sponsors, the practical effect is significant. Previously, the Home Office could only verify salary compliance during a physical compliance visit or by requesting documents from the sponsor. Now, UKVI will be able to carry out automated online checks comparing the salary stated on the Certificate of Sponsorship with the salary actually paid to the worker, as recorded in HMRC's systems. If the data does not match, the system will flag the discrepancy.

Importantly, from 8 April 2026, salary compliance will be assessed on a per-pay-period basis rather than on an annualised average. This means that a sponsor who pays a worker below the minimum threshold in any single month cannot compensate by paying extra in another month. Every individual payslip must meet the requirement. This is a major shift. Many employers have historically relied on annual bonuses or overtime to bring total compensation above the minimum. That approach will no longer work.

Compliance Visits: What to Expect

Compliance visits may be announced (with a few days' notice) or unannounced. During a visit, a Home Office compliance officer will typically ask to see the HR file for each sponsored worker, check that right-to-work checks have been carried out and documented in the prescribed format, verify that the worker is actually performing the role described on their CoS, check that salary payments match the CoS, inspect the workplace to confirm that the business is genuine and operating from the stated address, and interview the sponsored workers and their line managers.

The compliance officer will also check the SMS records against the employer's internal records. If reporting duties have not been met, for example if a worker changed their job title six months ago and this was never reported on the SMS, the officer will note it. Compliance visits are increasingly "intelligence-led," meaning the Home Office targets employers where data analysis has already identified potential problems. By the time an officer arrives, they often already know what they are looking for.

Consequences of Non-Compliance

The consequences range from an action plan to outright revocation. An action plan is issued when the Home Office identifies breaches that can be remedied within a specified timeframe. The employer is given a set period, usually 20 working days, to correct the problems and provide evidence of compliance. If the breaches are more serious, or if the employer has already been given an action plan and has failed to comply, the licence may be suspended. During suspension, the employer cannot assign new Certificates of Sponsorship, and existing sponsored workers may have their leave curtailed.

Revocation is the most severe outcome. It means the employer loses its licence entirely. All existing sponsored workers receive notice that their leave will be curtailed, typically to 60 days, within which they must find a new sponsor or leave the UK. The employer is barred from applying for a new licence for a period of at least 12 months, and in some cases permanently. Civil penalties for illegal working can reach up to 60,000 pounds per worker. Criminal penalties for knowingly employing illegal workers can include up to seven years' imprisonment.

Spring 2026 Guidance Updates

The Home Office published updated Sponsor Guidance on 6 March 2026, including revised versions of Appendix D (document retention) and the Skilled Worker guidance. Key changes include a new requirement for sponsors to retain evidence of the recruitment process for each sponsored worker, including the job advertisement, shortlisting criteria, and interview notes. The guidance also strengthens the requirement for sponsors to conduct ongoing monitoring of salary compliance, not just at the point of issuing a CoS. Additionally, the updated Appendix D now specifies that certain documents must be retained for the duration of sponsorship plus one year, rather than the previous requirement of the duration of sponsorship alone.

Practical Steps for Employers

Employers holding or applying for a sponsor licence should take several immediate steps. First, conduct an internal audit of all sponsored workers' files to ensure that record-keeping requirements are met. Second, review payroll records to confirm that every sponsored worker is being paid at or above the minimum salary in every pay period, not just on an annualised basis. Third, check the SMS to ensure that all required reports have been submitted and are up to date. Fourth, appoint a dedicated compliance officer within the organisation, separate from the Authorising Officer, whose role is to monitor compliance on an ongoing basis. Fifth, prepare for the HMRC data-sharing regime by ensuring that the salary figures on the CoS, the employment contract, and the payroll all match precisely. Any discrepancy, even a rounding error, could trigger an automated alert.

The UK sponsor licence system is no longer a set-and-forget process. It demands active, continuous management. Employers who treat it as an administrative afterthought are increasingly likely to find themselves facing suspension, revocation, and the disruption that follows.
