Residence at receipt is the deciding fact
A gratuity treated as earnings from your UAE employment is taxed by reference to the year of receipt and your residence in that year, not the years you earned it. That produces three scenarios: received while non-UK resident for UAE duties, generally outside UK tax; received after you have become UK resident with no relief available, potentially taxable in full at your marginal rate; or received in a split year, where everything turns on whether the tax point falls in the overseas part or the UK part. Your status is set by the Statutory Residence Test, and the split-year rules can keep a payment received before the UK part of your arrival year begins outside the charge even though you move to Britain later that same tax year. Because the tax point is the earlier of payment and entitlement, the exact dates agreed with your employer carry real money.
Why the usual reliefs rarely help
Two reliefs sound promising and usually disappoint. The £30,000 tax-free threshold under sections 401 to 403 ITEPA 2003 applies to genuine compensation for loss of employment, not to sums your employer was already obliged to pay, and a statutory UAE end-of-service gratuity is by nature a contractual and legal entitlement that accrues over your service, so HMRC frequently characterises it as earnings taxable in full. Only a separately negotiated ex gratia severance element is likely to qualify. Foreign service relief, which once exempted or reduced termination payments for long-serving expatriates, was withdrawn from 6 April 2018 for anyone UK resident in the tax year the employment ends, surviving mainly for seafarers and for those still non-resident in the termination year. For most people coming home from the Gulf, neither relief rescues a gratuity that lands inside the UK charge.
Time the payment around your return
The most powerful lever is sequencing: become entitled to and receive the gratuity while still clearly non-resident, before any UK part of a split year begins. Fix your leaving date and the payment date, check both against your projected residence position for the year of arrival, and do not assume a late payment that arrives after you land carries the same treatment as one settled before departure, because the later tax point can pull it into charge. Keep evidence of when the employment ended, when the money was paid and that it relates to UAE duties.
