Tens of thousands of British expats are grappling with unexpected tax liabilities after fleeing the Gulf region amid escalating conflict involving Iran, with many returning to the UK on emergency flights. Accountancy firm Price Bailey warns that these individuals risk falling afoul of Britain’s strict five-year temporary non-residency rule, designed to prevent tax avoidance through short-term relocations.
Under this regulation, expats who resume UK tax residency within five full tax years may face capital gains tax on foreign assets sold while abroad. Sandra Jeevan, a partner at UHY Hacker Young, noted that many families, forced back by the crisis, are unprepared for the financial consequences of altering their residency status. She emphasized the challenge of navigating complex day-count rules and technical residency tests during a chaotic evacuation.
The conflict has inflicted visible damage across the UAE, with iconic structures like the Fairmont The Palm and Burj Al Arab hotels sustaining hits. Drone attacks near Dubai International Airport injured four people earlier this week, while falling debris from an intercepted drone in Abu Dhabi claimed one life and injured seven at the war’s outset.
HMRC has acknowledged that war can qualify as an exceptional circumstance under residency rules, but Jeevan argues the agency’s interpretation remains overly narrow, often excluding prolonged stays in the UK for family support post-crisis. She has called for a more sympathetic approach given the extraordinary situation.
Around 140,000 Britons in the UAE had registered with the Foreign Office for assistance, with estimates suggesting up to 300,000 British citizens were in Gulf countries when airstrikes by the US and Israel on Iran began. Several banks have also urged employees to evacuate offices in Qatar and the UAE as Iran threatened strikes on financial hubs.
The tax implications are stark—returning expats must typically remain outside the UK for an entire tax year to shield foreign income from British taxation, a threshold many may now fail to meet.
