Thousands of British expatriates fleeing the escalating conflict in the Middle East are calling on the British government to clarify whether they will face unexpected tax charges if they return to the UK earlier than planned.
Tax experts warn that some of the approximately 160,000 British nationals living in the region, including many based in Dubai, could inadvertently breach the UK’s tax residency rules if their emergency declaration exceeds the threshold of 183 days spent in the country in the current financial year.
The UK tax year ends on April 5, meaning the timing of the crisis could have significant financial consequences for expatriates who were already close to the residency limit before the conflict intensified.
Under the UK statutory residence test, individuals who stay in the UK for 183 days or more within a tax year are generally considered to be subject to UK tax. If this threshold is exceeded, global income, including income earned abroad, may become taxable in the UK.
For many British expatriates who have relocated to the United Arab Emirates specifically to benefit from its largely tax-free regime, such a change in residency status could result in a significant and unexpected tax liability.
Concerns have been heightened by the sudden deterioration in security in parts of the Gulf following US-Israeli attacks on Iran and retaliatory strikes by Iranian forces. Drone strikes reportedly targeted infrastructure in the UAE, including parts of Dubai, prompting some expatriates to temporarily return to the UK with their families.
Sandra Jeevan, partner at accounting firm UHY Hacker Young, said the situation had caused great concern among expatriate families who had left the region mainly for safety reasons.
“We are hearing from many families who never had any intention of returning to the UK this year but have now had no choice,” she said. “You could be exposed to the UK tax burden simply because your emergency declaration changes your UK residency position.
“If you’re trying to keep your family safe, don’t focus on day count rules or technical residency tests.”
UK tax rules allow for limited flexibility in certain circumstances. HM Revenue & Customs allows individuals to disregard up to 60 days spent in the UK if those days are due to “exceptional circumstances” beyond their control.
Events such as war, civil unrest, natural disasters or sudden travel restrictions may potentially fall under this provision. However, tax advisors warn that the exemption is narrow and subject to narrow interpretation.
For example, HMRC guidance states that remaining in the UK for personal reasons after the immediate crisis has passed, such as to remain with family or to delay a return abroad, should not be treated as an exceptional circumstance.
This creates uncertainty for expatriates who may initially return for security reasons but remain in the UK for several weeks while they assess the evolving situation in the region.
Nimesh Shah, managing director of consultancy Blick Rothenberg, said the number of inquiries from UAE-based expatriates has risen sharply in recent weeks.
“I received a disproportionate number of calls from people wanting to leave the UAE,” he said. “But I have advised them not to rely too much on the exceptional circumstances provisions.
“HMRC is likely to take the view that people have chosen to move abroad primarily to benefit from a low tax environment. They may therefore be reluctant to allow longer stays in the UK without incurring residency consequences.”
As a result, some expatriates are reportedly considering temporarily relocating to other countries rather than returning directly to the UK. Countries such as Ireland or France are being examined as short-term alternatives that would allow individuals to stay outside the UK long enough to avoid breaching the 183-day rule.
The issue highlights the complex interaction between international mobility and tax residency rules in times of geopolitical crises.
While the UAE has emerged as a major destination for British professionals over the last decade, particularly in sectors such as finance, property and technology, the region’s exposure to geopolitical tensions means that sudden moves can quickly lead to tax complications.
A spokesman for HM Revenue & Customs said the existing framework already provides protection for people who find themselves in exceptional situations.
“The existing rules provide the right protections while following the fundamental principle that people living in the UK should pay tax in the UK,” the spokesman said.
“Extraordinary circumstances, such as being affected by war, are taken into account.”
But advisers say more clarity from the government would help provide reassurance to expatriates making urgent decisions about their safety.
With the end of the tax year fast approaching, many people are now urgently seeking professional advice to assess their immigration status and determine whether an emergency trip could result in a significant UK tax liability.
