Wealthy British nationals fleeing Gulf conflict bypass UK to avoid tax bills

Wealthy British nationals living in the United Arab Emirates (UAE) and neighbouring Gulf states are choosing to relocate to countries such as Ireland and France rather than return to the United Kingdom amid rising conflict in the region — a decision driven largely by concerns over the UK tax system as the current tax year draws to a close.
With only a few weeks left before the 2025–26 UK tax year ends on 5 April, many high‑net‑worth individuals who have established non‑resident status are hesitant to risk returning home for fear of triggering significant tax liabilities. The UK’s tax authority, HM Revenue & Customs (HMRC), counts the number of days an individual spends in the UK as a key determinant of tax residency; exceeding allowable days could make a non‑resident liable for UK income tax and capital gains tax on worldwide income and gains.
Conflict prompts decisions rooted in tax, not safety
The rising conflict in the Gulf region has forced many Britons to contemplate where to regroup. Rather than risk being treated as UK tax residents by spending too much time in Britain — and potentially face retroactive taxation — they are instead flying to countries perceived as more tax favourable until the new UK tax year begins. Ireland and France have become popular temporary destinations, offering a buffer until Britons can return without altering their tax status.
A wealthy business owner, speaking to The Guardian, said he was spending time in Dublin to avoid returning prematurely to London, which could have triggered capital gains tax on assets or businesses that had been sold while he was abroad. “I’m happy to pay income tax and tax on investments next tax year, but I don’t want the sale of a business that I sold years ago to fall within UK capital gains tax,” he said.
Exceptional circumstances relief unlikely
Some expatriates hoped that current travel advisories related to the conflict might qualify them for HMRC’s “exceptional circumstances” rule — a provision that, in the past (notably during the COVID‑19 pandemic), allowed flexibility over residency tests for people unable to leave certain regions. But tax professionals warn that HMRC is unlikely to be sympathetic, noting that governments generally don’t consider advisory alerts sufficient to trigger tax‑year leniency.
Nimesh Shah, chief executive of tax advisory firm Blick Rothenberg, told The Guardian that the current situation around the Gulf does not meet the stringent criteria HMRC applies for exceptional circumstances. “In HMRC’s mind they’ve chosen to go [to the UAE] to not pay tax in the UK,” he said, adding that those leaning on that provision may be disappointed.
Tax rules and residency traps
Under UK tax law, the Statutory Residence Test governs whether an individual is considered a UK resident for tax purposes. Spending too many days in the UK — typically more than 90 or 120 in a year, depending on circumstances — can trigger residency status. Once deemed resident, individuals may face income tax on worldwide earnings and capital gains tax (CGT) on gains realised abroad, including sales of businesses or investment assets.
Those who have been non‑resident for fewer than five full tax years are particularly vulnerable. If they return and restart UK residency status, the UK’s Temporary Non‑Residence (TNR) rules could subject them to CGT on gains made while they were outside the country — even if those gains occurred years earlier.
Broader context: wealthy Britons and tax migration
This latest bout of relocation sits within a wider debate over the UK’s changing tax landscape. In recent years, reforms to the so‑called “non‑domiciled” tax regime and moves to tax worldwide income more comprehensively have prompted some wealthy individuals to reconsider their tax affairs and, in some cases, their residency. While broader “millionaire exodus” claims are contested and likely exaggerated, these current moves reflect how tightly the timing and interpretation of tax laws influence where the wealthy choose to live during periods of geopolitical stress.
Public reaction and policy implications
Reaction among the public and on social media has been mixed. Some commentators argue that if wealthy Britons benefit from UK services — including evacuation support — they should contribute to the tax base. Others take a more laissez‑faire view, noting that existing residency rules allow people latitude in where they live and pay tax, and that individuals often make these choices for legal, financial reasons rather than a disdain for their home country.
For policymakers, these developments highlight ongoing tensions between tax competitiveness and fairness — a debate that is likely to continue as the UK navigates the post‑Brexit economic and political landscape.
