Overseas Workday Relief can reduce UK tax on the part of an employeeβs earnings that relates to work genuinely carried out abroad, for those who qualify under the current regime. This guide explains how it works for 2026/27 and what records support a claim.
What Overseas Workday Relief Is
Overseas Workday Relief applies to certain employees who are UK tax resident but who were not previously long-term UK resident, and who have both UK and overseas employment duties, allowing the portion of their earnings that relates to work days genuinely spent performing duties outside the UK to be treated differently from earnings relating to UK workdays.
It reflects the principle that someone newly resident in the UK, still carrying out part of their role abroad, should not necessarily be taxed in the UK on their full worldwide employment income in the same way as someone who has always worked wholly in the UK β the relevant conditions and time limits have changed with recent reforms to the wider regime for new UK residents, so current eligibility should always be checked.
How Earnings Are Apportioned
Where relief applies, earnings are typically apportioned between UK and overseas workdays based on the actual number of days worked in each location during the relevant period, rather than a rough estimate, meaning accurate day-counting is essential to support the apportionment used.
Bonuses, benefits and other elements of pay may need separate consideration depending on the period they relate to, since a bonus earned over a period spanning both UK and overseas work may need to be apportioned across that whole period rather than treated by reference to a single date.
Record-Keeping for a Claim
Because a claim depends on demonstrating exactly how many days were worked where, detailed contemporaneous records β travel dates, work location logs, and calendars showing which days were UK workdays versus overseas workdays β are essential to support the apportionment if HMRC queries the claim.
Given how much the wider rules for newly UK-resident individuals have changed in recent years, anyone considering a claim should check the current conditions and take professional advice, since eligibility depends on personal residence history as well as the nature of the employment.
Frequently Asked Questions
Who can generally claim Overseas Workday Relief?
It is aimed at certain UK tax resident employees who were not previously long-term UK resident and who have employment duties performed both in the UK and overseas β the precise qualifying conditions have been affected by wider reforms to how new UK residents are taxed, so current eligibility needs checking against the rules in force.
How are earnings split between UK and overseas work?
Broadly, by reference to the actual number of days spent performing duties in the UK compared with overseas during the relevant period, so accurate, contemporaneous records of where work was actually carried out each day are central to supporting any apportionment.
Do I need to keep detailed records to claim this relief?
Yes, very much so β because the relief depends on an accurate day-by-day apportionment of earnings, keeping travel records, calendars and evidence of where duties were performed is essential in case HMRC queries the basis of a claim.

Does a bonus get apportioned in the same way as regular salary?
It can, but the correct treatment depends on the period the bonus relates to β a bonus that reflects work carried out over several months spanning both UK and overseas duties may need apportioning across that whole reference period, not by reference to the single date it is paid.
Has Overseas Workday Relief changed recently?
The wider regime for newly UK-resident individuals β of which this relief forms part β has been reformed in recent years, changing qualifying periods and conditions, so it is important to check the current rules rather than relying on older guidance.
Should I get professional advice before relying on this relief?
Yes β because eligibility depends on personal residence history, the structure of the employment, and precise day-counting rules, professional tax advice is strongly recommended before claiming, particularly where significant sums of overseas income are involved.
Does Overseas Workday Relief also affect National Insurance?
No β the relief operates on the income tax treatment of earnings only; National Insurance liability is generally governed by separate rules, including any applicable social security agreements or certificates of coverage, so it needs to be considered independently.
Do I need to make a formal claim, or is it automatic?
Relief is not automatic β it typically needs to be claimed through Self Assessment, supported by the day-count apportionment and records showing where duties were performed, so anyone who thinks they qualify should factor this into their tax return process.
Does it matter where my earnings are actually paid or held?
It can β how and where employment income is remitted or received may affect the practical tax treatment alongside the day-apportionment itself, so the interaction between apportionment and remittance-related rules should be checked as part of any claim.
Is this relief only available in the year I first arrive in the UK?
It is aimed at a limited window after becoming UK tax resident rather than being available indefinitely, and the length of that window has been affected by recent reforms, so the current qualifying period should be confirmed rather than assumed.
