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

While a worker holds a Skilled Worker visa, your SMS duties are ongoing. You report salary changes, role changes, absences beyond four weeks, and any change to the worker's employment status all within strict 10-working-day windows. Missing a deadline, even through an administrative oversight, can trigger a downgrade of your sponsor licence rating.

ILR ends all of that for the individual concerned. You no longer need to track their salary against the sponsored rate, report unpaid leave, or flag changes to their job title or working pattern. They become, for immigration purposes, the same as any UK citizen or settled worker on your payroll.

One practical step worth building into your HR process: when an employee notifies you of their ILR grant, log it immediately and update your internal tracking system. Then submit the SMS report. Keep a copy of the confirmation. That record protects you if the Home Office later queries when sponsorship ended. 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 ISC is charged at the point of assigning a Certificate of Sponsorship, covering the sponsorship period paid upfront. For large employers, that is £1,320 for the first 12 months and £660 for each subsequent six months a rate that rose 32% from December 2025. For small and charitable sponsors, the equivalent figures are £480 and £240.

Once ILR is granted, you will never pay ISC for that employee again. There is no CoS to assign, so no charge arises. This is one of the most tangible financial benefits of reaching ILR: a worker who previously cost £1,320 per year in ISC alone now costs nothing in sponsorship fees to retain.

Some HR teams assume they can get a partial ISC refund when a worker transitions from their Skilled Worker visa to ILR ahead of the CoS end date. They cannot. Refunds only arise in specific scenarios the visa is refused, the worker does not start, or they leave the company and leave the UK. Switching from sponsored leave to ILR while remaining employed with you does not trigger a refund, because the sponsorship charge is tied to the visa route, not to how long you continue employing them. Plan your CoS assignment dates carefully to avoid paying ISC for periods your employee will spend on ILR status.

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 ILR application fee in 2026 is £3,226 per person. For families with dependants, costs scale quickly. Employers who fund ILR fees as part of their total reward package tend to have a retention advantage at the five-year mark precisely the point when internationally mobile employees are most likely to consider their options.

Unlike the ISC, the ILR application fee is not legally restricted from clawback. If your company funds it as a benefit, you can include a repayment clause provided the clause is proportionate, clearly documented, and uses a sliding-scale structure. A repayment schedule that demands full reimbursement two years after ILR is granted would likely be challenged as unreasonable. A schedule that reduces the repayment obligation by 20% for each six months of continued employment post-ILR is far more defensible.

The reality is that most companies still have no formal ILR funding policy at all. They address it case by case, which creates inconsistency and, occasionally, legal exposure. If your mobility policy covers Skilled Worker visa costs but is silent on ILR fees, now is the time to fix that. For context on how ILR costs fit into the broader picture of UK immigration fees in 2026, including the full cost-per-hire breakdown, it is worth reviewing your budget assumptions against current government fee schedules.

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 reaches ILR reduces your ongoing sponsorship cost base. No more ISC. No more CoS fees. No more SMS compliance tracking. For companies with 20, 50, or 200 sponsored workers approaching their five-year anniversary, that is a material reduction in administrative and financial overhead provided those employees actually apply for ILR on time.

The risk, which many HR teams underestimate, is that employees delay or miss their ILR window. That means continued sponsorship costs, continued SMS obligations, and in some cases a visa expiry that disrupts employment. Proactive tracking of ILR eligibility dates across your sponsored workforce is not just good practice; it is genuinely cost-reducing. 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.

ILR is not the end of your relationship with an employee it is the start of a simpler one. Use it as an opportunity to remove complexity from your compliance stack, review your mobility policy, and set a more sustainable foundation for your international workforce.
