UK ILR: When Does Employer Sponsorship Liability End?

Key Take aways for Sponsorship Liability

Sponsorship ends the moment ILR is granted you can stop all SMS reporting and CoS tracking for that employee immediately
The Immigration Skills Charge is never owed again once ILR removes the employee from the sponsored route
You cannot reclaim ISC from employees under any circumstances but you can build a clawback policy around other government fees such as the ILR application fee (£3,226 in 2026)
A legally sound clawback clause must exclude ISC, be proportionate, and use a sliding-scale repayment schedule
Proactively managing the ILR transition across your workforce reduces long-term sponsorship costs and SMS compliance burden

The Day Employer's Sponsorship Obligations Stop

Most HR teams know what it takes to sponsor a Skilled Worker. Fewer are clear on when that responsibility actually ends. The answer is cleaner than many expect: your sponsorship liability ends the day ILR is granted.

From that point, your employee no longer holds leave tied to your organisation. They can stay in the UK permanently, change roles, change employers, or do nothing all without any involvement from you. For you as a sponsor, this means three things stop immediately:

SMS reporting duties for that individual
Obligation to maintain their CoS records as an active sponsorship
Any future ISC liability for their continued employment.

You must report the end of sponsorship via the Sponsor Management System (SMS) within 10 working days of becoming aware that ILR has been granted. After that, the file closes.

What "Stopping SMS Compliance" Actually Means

Sponsoring a Skilled Worker is high-maintenance. You are bound by strict 10-day windows to report salary tweaks, role changes, or long absences. Mess up a deadline, and your sponsor licence rating takes the hit.

Indefinite Leave to Remain (ILR) changes everything. The moment your employee gets ILR, the compliance burden vanishes for that individual. No more tracking their pay, flagging unpaid leave, or reporting job title updates. On your payroll, they are now treated just like any UK citizen.

Your Final Action

To officially close the loop, update your internal HR tracker and submit one last report on the SMS stating that sponsorship has ended. Keep a copy of the confirmation. It is your safety net if the Home Office ever comes knocking with questions later.

For teams managing multiple sponsored workers, a structured ILR support process makes this transition systematic rather than reactive.

The Immigration Skills Charge: When Employer Stop Paying

The Immigration Skills Charge (ISC) is a hefty upfront cost when assigning a Certificate of Sponsorship (CoS). For large employers, it’s £1,320 for the first year and £660 for every six months after. For small businesses or charities, it’s £480 and £240.

Once your employee gets Indefinite Leave to Remain (ILR), you never pay the ISC for them again. Because you no longer need to issue a CoS, a worker who previously cost you over £1,300 a year in fees suddenly costs nothing to retain.

The Refund Myth

A common trap for HR teams is expecting a partial ISC refund if an employee gets ILR before their CoS expires. You won't get one. The Home Office only issues refunds if a visa is refused, the worker never starts, or they leave your company entirely. Moving from a Skilled Worker visa to ILR while staying on your payroll doesn't qualify. To avoid wasting money, time your CoS extensions carefully so you aren't paying for sponsorship months your employee will actually spend on ILR.

The One ISC Rule That Cannot Be Broken

You cannot pass the ISC to the employee. Not directly, not through a salary deduction, not through a repayment clause in a contract. The Immigration Skills Charge Regulations 2017 place liability squarely and exclusively on the sponsoring employer. Any attempt to recover it from the worker who just received ILR or from anyone else exposes your organisation to enforcement risk and potential licence consequences.

This matters when designing your ILR funding and clawback policy. ISC must be carved out explicitly. If your contract currently includes a blanket clawback on "all immigration costs," it is worth reviewing whether that language inadvertently captures ISC payments. It should not.

Funding ILR Applications: Should You Pay, and Can You Claw It Back?

The standard Indefinite Leave to Remain (ILR) application fee is a massive £3,226 per person. For employees with families, that bill multiplies fast. Covering these costs as part of your benefits package gives you a massive retention advantage right at the five-year markthe exact moment international talent is most likely to look elsewhere.

Yes, You Can Claw It Back

Unlike the Immigration Skills Charge, the law allows you to claw back ILR application fees if an employee leaves. However, it must be reasonable and structured.

What fails: Demanding a 100% refund if they leave within two years of getting ILR. A tribunal will likely throw this out as an unfair penalty.
What works: A sliding scale. For example, reducing the amount they owe by 20% for every six months they stay with you post-ILR. It is fair, transparent, and legally defensible.

Stop Handling It Case-by-Case

Most companies don’t have a formal ILR funding policy; they just make it up as they go. This creates unfair inconsistencies and opens the door to legal risks. If your current mobility policy covers normal visa costs but stays silent on ILR, it is time to write it down. Take a look at your 2026 hiring budget and decide upfront how you will handle these UK immigration fees.

ILR Funding Policy Options

Policy Approach	Employer Pays?	Clawback Possible?	Best For
Full employer funding, no clawback	Yes	No	High-retention roles, senior hires
Full employer funding, sliding-scale clawback	Yes	Yes (proportionate)	Most sponsored workforces
Employee pays, employer reimburses post-ILR	Delayed	No	Cash-flow-constrained organisations
Employee pays entirely	No	N/A	Not recommended, increases attrition risk at Year 5

Designing a Clawback Policy That Holds Up

If you fund ILR fees and want a clawback clause, it needs to meet a few basic requirements to be enforceable.

The clause must be in writing and agreed before the benefit is provided not added to a contract after the fact.
Second, it must specify which costs are covered. Include the ILR application fee and any legal fees your company absorbed. Exclude ISC explicitly.
Third, the repayment obligation must reduce over time. A two-year sliding scale is common; some employers use 18 months. The period should reflect the value of the investment and the typical retention risk window.

Finally, define the trigger clearly. Most clawback clauses trigger on resignation or dismissal for cause within the repayment period. Consider whether you also want it to trigger on a transfer to a non-sponsored role that effectively removes the business benefit of the investment.

For a clearer picture of your obligations in supporting employees through this process, including what goes into the ILR employer support letter and the records you need to provide, that groundwork affects both the application outcome and your compliance position.

Right-to-Work After ILR: One Step People Miss

When an employee moves from a time-limited Skilled Worker visa to ILR, their right-to-work evidence changes. ILR is now confirmed via an eVisa share code, not a physical BRP card. Your team needs to conduct a follow-up right-to-work check and update the employment record accordingly.

This is not optional. Failing to update right-to-work records when a status change occurs leaves your organisation exposed during a compliance audit. It is also one of the clearest signals of a well-run mobility function versus one that treats ILR as purely the employee's problem.

Once that check is done and the SMS report is filed, your obligations for that individual are complete. They are, from an immigration standpoint, free and so are you.

What This Means for Your Long-Term Workforce Strategy

Every employee who transitions to Indefinite Leave to Remain (ILR) is a financial win for your business. It instantly wipes out ongoing sponsorship costs: no more ISC, no more CoS fees, and zero SMS compliance tracking. For companies with dozens of sponsored workers hitting their five-year milestone, this means a massive reduction in overhead but only if employees actually apply on time.

The Risk of Delay

When employees delay their ILR applications, your business pays the price. You are stuck footing the bill for continued sponsorship, managing SMS obligations, and risking visa expiries that can disrupt your operations. Proactively tracking ILR eligibility dates isn’t just an administrative task; it’s a direct cost-saving strategy.

A Simpler Way Forward

ILR doesn't mean saying goodbye to an employee; it means saying goodbye to their paperwork. Use these milestones to strip complexity out of your compliance stack, update your mobility policies, and build a more sustainable international team.

For teams thinking about whether to manage this in-house or through a specialist provider, the managed service versus in-house cost comparison is worth reviewing before making that call.
