What UK employers must establish before ending the employment of someone who has been working from another country.
Context and challenge
Allowing an employee to work abroad often starts as an informal concession. Months later the employer may have no local entity, no registered payroll, no immigration plan and a contract framed on UK-only assumptions. The main challenge is that the exit — not the original move — is usually when the accumulated exposure becomes visible, and by then the facts are fixed. Common symptoms: a UK payslip assumed to settle the whole position; a settlement figure agreed before the host-country and UK tax analysis; no record of where duties were actually performed.
Who should read this
UK employers, HR directors, finance directors, reward leaders, founders and advisers managing an employee who has been working outside the UK without a formal assignment framework.
Core finding (TL;DR)
The most serious liabilities in an overseas remote-worker exit usually accrued before the exit, not on termination. Map employment rights, payroll, social security, pensions, equity, immigration and corporate-tax footprint across every country involved before agreeing terms. The UK £30,000 termination threshold is not a blanket exemption, and foreign service relief is unavailable to UK-resident leavers.
Decision point
Where did the individual actually work, under whose direction and for how long; what rights and obligations arose there; and which must be resolved before, during and after the exit?
The issue
Trigger: an employee has worked habitually in another country on a UK contract, and the relationship is ending.
Why it matters: local employment rights, host payroll/social security, UK tax on the payment, equity, immigration and a possible corporate footprint may all be unresolved.
Decision needed: map the whole relationship across every country and confirm the exit is legally executable where the person worked — before terms are agreed.
Technical analysis
1. Local employment rights
A choice-of-UK-law clause does not automatically displace the mandatory protections of the country where the employee habitually worked. A short period abroad differs from months or years of consistent working in one place. Host protections may include notice, severance, protection against dismissal and procedural steps. This is an HR and governance assessment, not a substitute for a host-country legal opinion: “they’re on a UK contract” is not a reliable answer, and an agreed settlement may need locally compliant documentation, translations, authorised signatures, statutory notifications or a cooling-off period before it is enforceable.
2. UK tax treatment of the termination payment
The £30,000 figure is not a blanket exemption. Since 6 April 2018, ss.402A–402E ITEPA split a termination award in two. Post-employment notice pay (PENP) — broadly the basic pay for any unworked notice — is taxed in full as general earnings, with employee and employer Class 1 NICs, even where the PILON is neither contractual nor customary; it gets no threshold. Statutory redundancy pay sits outside PENP. Only the balance, taxed as specific employment income under s.403, benefits from the £30,000 threshold, above which income tax applies and, on the excess, employer Class 1A NICs (from 6 April 2020). Before final payroll, establish how each element is characterised, in which country, and who bears any arrears.
3. Residence, foreign service relief and non-resident apportionment
The UK treatment turns heavily on residence in the tax year the employment ends. Since 6 April 2018, foreign service relief is unavailable to any leaver who is UK-resident in the year of termination (ss.413–414; seafarer carve-out aside). Non-resident leaver: for terminations on or after 6 April 2026, two mutually exclusive routes — foreign service reduction under s.414, which reduces both PENP and the s.403 element; or the globally-mobile rule in s.38A ITEPA 2003, which addresses the PENP only. s.38A is a deeming rule with a UK default: PENP is treated as relating to UK duties except so far as the notice-period duties it is reasonable to assume would have been performed would have been done outside the UK — so without evidence of where those duties would have been performed, the default is UK. The leaver takes whichever produces the better overall result across the whole award, and cannot use s.38A after claiming under s.414; s.38A is available for 2026/27 terminations, not automatic. Split-year leaver: still UK-resident for the year, so foreign service relief does not apply; the relief here is the separate split-year attribution — PENP is not charged to the extent it relates to the overseas part, on a just and reasonable basis. The s.403 element is chargeable irrespective of residence, so the treaty and OECD Article 15 commentary decide taxing rights.
4. Social security and PAYE — a two-way exposure
Social security is a separate analysis from income tax, and it also decides whether UK Class 1 NICs are due on PENP at all. An A1 or certificate of coverage may support home-country contributions, but only if its conditions are met and it covers the period; if the individual properly sits in the host system, UK NICs on PENP may be the wrong answer, and the opposite error is equally possible. The same symmetry applies to PAYE: an informally relocated employee is often left on full UK PAYE when UK tax was not in fact due on all of it, or when relief should have been claimed — leaving double taxation, credit or refund claims to unwind at exit. Check coverage, contributions and PAYE operation across the whole period, in both directions.
5. Pensions, benefits, share plans and equity
Overseas working can disturb pension contributions (UK auto-enrolment and host requirements, each on their facts), insurance cover and outstanding claims. Equity needs particular care: options, RSUs and other awards may be sourced, withheld and reported across the vesting period, and the taxable location may not be where the individual sits on the termination date — record workdays, leaver status and award terms before any acceleration, forfeiture or settlement. Where part of a settlement is delivered in shares or other readily convertible assets, keep section 222 ITEPA in view: if the employee does not make good the PAYE on that notional payment within 90 days of the end of the tax year in which it is treated as made, the unrecovered tax itself becomes further taxable earnings — a disproportionate charge (tax on the unrecovered tax) that is easily avoided by timely make-good.
6. Corporate footprint, immigration and closing out
An employee operating abroad can, in some circumstances, raise a permanent establishment, corporate-tax or registration issue — particularly where they habitually conclude contracts or carry on substantive revenue-generating activity; home-working alone does not automatically create a PE, but the exit does not erase a footprint that has already arisen. Immigration needs separate analysis for both countries: a remote worker may have been on an unsuitable route abroad, and where a UK sponsor stops sponsoring a worker the report to the Home Office is normally due within 10 working days under the sponsor guidance (a sponsored worker allowed to relocate abroad also creates earlier reportable changes — absence, work location, pay). Closing out with no local entity needs practical cooperation to complete payroll, tax, benefits, immigration and documentation; the financial close-out — leases, school fees, shipping, insurance, reimbursements — can run well beyond the agreed termination sum.
Case scenario: UK contract, long-term remote working in Portugal
Anonymised, illustrative. Country-specific obligations depend on the facts.
Situation: A UK company allowed an employee to relocate to Portugal for an extended period, without scoping the employment, payroll, social-security or immigration implications.
Issue: The relationship deteriorated; the employee took local advice while still in Portugal. Portuguese employment rights and pay entitlements (including holiday and Christmas allowances), payroll registration, social security, immigration and insurance all surfaced.
Analysis: Habitual working from Portugal required a host-country assessment; the UK contract and payroll could not be assumed to settle the position — though that does not make a UK contract simply “invalid” in Portugal. On the UK side, the same facts raise whether the employee became non-UK resident or had a split year on moving; how that affects the UK charge on PENP and the s.403 element; whether UK PAYE and NICs were correctly operated; and how the UK–Portugal treaty allocates taxing rights over the termination payment.
Outcome: The exit could not safely be treated as a UK-only settlement. Local and UK obligations had to be scoped before deciding how to document, pay for and implement the separation.
Lesson: Liabilities build up during the remote-work period; the exit is simply when they become visible.
Fenton International’s advisory position
| Technical position | Mandatory host-country rights and historic host/UK payroll, social-security and tax positions frequently govern the outcome more than the termination date; the UK charge depends on residence and the PENP/s.403 split, not the £30,000 figure alone |
|---|---|
| Professional judgement required? | Yes — residence status, treaty attribution, host-law enforceability, PE risk and the s.38A-vs-s.414 choice are fact-specific judgement calls, not mechanical application |
| Main risk | Liabilities accrued during the remote-working period surfacing, unprovided-for, at exit — across tax, payroll, social security, immigration and corporate footprint |
| Evidence needed | Work locations and dates; contract and mobility permissions; management structure; payroll and tax filings; social-security records; pension/benefits data; share-plan documents; immigration and sponsorship records; local legal analysis; settlement terms and approval trail |
| Recommended controls | Map the whole relationship across jurisdictions before agreeing terms; confirm executability where the person worked; run the UK residence and termination-payment analysis before final payroll; allocate close-out responsibilities in writing |
Professional judgement & advisory application
This is not a mechanical calculation. Judgement is required where facts are incomplete, where residence or treaty positions conflict, and where employment-tax outcomes interact with immigration and corporate tax. Fenton’s judgement and recommendation: treat an overseas remote-working arrangement as a governance issue throughout its life, not a payroll footnote at the end — scope the position across every country involved, document the basis for each position taken, and resolve it before the exit conversation becomes irreversible. Risk level: medium to high where there is habitual overseas working with no local entity or assignment framework.
Frequently asked questions
Can an employer end the relationship on UK contract terms alone?
Not necessarily. Mandatory local employment protections and procedural rules may apply where the person habitually worked, regardless of a UK governing-law clause. An agreed settlement sum does not close the position: confirm which jurisdiction’s rules apply and whether the exit documents and process will be enforceable there before terms are finalised.
Is the first £30,000 of a termination payment always free of UK tax?
No. Only the part taxed as specific employment income under s.403 ITEPA can benefit from the £30,000 threshold. Post-employment notice pay, unpaid salary, bonuses and holiday pay are taxed in full as earnings, with Class 1 NICs. Above £30,000, income tax applies, with employer Class 1A NICs on the excess (from 6 April 2020).
Does the employee’s residence change the UK tax on the payment?
Yes, significantly. Foreign service relief is unavailable to any leaver who is UK-resident in the year the employment ends — including a split-year leaver, who instead gets split-year attribution so PENP is not charged to the extent it relates to the overseas part. A leaver non-resident for the year can choose, for terminations from 6 April 2026, between foreign service reduction (s.414, covering the whole award) and the s.38A rule (PENP only), taking whichever gives the better overall result.
Can a remote worker create a tax presence for the employer?
Potentially. Depending on the activities and local law, an employee abroad can raise a permanent establishment or registration issue — most often where they habitually conclude contracts or carry on substantive revenue-generating work. A remote-worker exit does not remove a footprint that has already arisen; a fact-specific review is needed.
