Moving to Dubai from the UK: Exit Tax and Non-Dom Status Checklist

The UK has no general exit tax — there is no deemed disposal of your worldwide assets simply for leaving. What it has instead is a residence-based system, rewritten from the ground up on 6 April 2025, that decides how long the UK keeps taxing your income and, more consequentially, your estate after you have gone. If you are researching this move using a guide written before 2025, its central premise — claiming non-dom status — no longer exists. This checklist works from the current rules.

Non-Dom Status No Longer Exists

This is the single most important fact for anyone planning a UK-to-Dubai move. Non-domiciled status, in the form it existed for over 200 years, was abolished on 6 April 2025. Domicile no longer determines your UK income and capital gains tax position at all. If an article talks about claiming the remittance basis, or paying an annual £30,000 or £60,000 charge to shelter foreign income, it is describing a regime that has been replaced.

What replaced it is the Foreign Income and Gains (FIG) regime, built on residence rather than domicile.

How the FIG Regime Actually Works

• Eligibility requires at least 10 consecutive years of non-UK tax residence immediately before arrival in the UK.
• Relief runs for a maximum of 4 tax years of UK residence, during which qualifying foreign income and gains can be fully exempt from UK tax, provided they are quantified and designated on a Self-Assessment return.
• Overseas Workday Relief (OWR) runs alongside it for the same first 4 years, exempting the overseas-earned proportion of employment income.
• The Temporary Repatriation Facility (TRF) is separate — it lets individuals who previously used the old remittance basis bring pre-2025 unremitted foreign income and gains onshore at a reduced rate: 12% for 2025/26 and 2026/27, rising to 15% for 2027/28. Designations must be made by 5 April 2028.

For someone moving from Dubai to the UK, this is genuinely useful for four years. For someone currently in the UK considering a move to Dubai, its relevance is different: the FIG regime only becomes available again after another 10 consecutive years of non-UK residence, which is the qualifying condition, not a switch you can turn on immediately after arriving in Dubai.

Worked Example: The FIG Clock

A finance professional who has lived in the UK continuously since childhood moves to Dubai in August 2026 to take up UAE employment.

• 2026 to 2036: Genuinely non-UK resident throughout, working and living in Dubai. Foreign income and gains during this period are simply outside UK tax — there is no FIG regime to claim because there is no UK residence to relieve.
• If they return to the UK in 2036, having completed 10 consecutive non-resident years, they now qualify for the FIG regime themselves: 4 tax years of UK residence with full relief on foreign income and gains, provided they are properly designated.
• If they returned after only 6 years abroad instead, they would not meet the 10-year qualifying condition and would be taxed on worldwide income from the point of return, with no FIG relief available.

The FIG regime is best understood as a re-entry benefit for long-term leavers, not an in-year relief for people currently resident. It matters to this checklist mainly as a marker of how long a clean break needs to last to reset your position fully.

Inheritance Tax: The Part That Follows You to Dubai

This is where the 2025 reform has real teeth for anyone who has already spent years in the UK. UK Inheritance Tax moved from a domicile-based system to a residence-based one on 6 April 2025. Your worldwide estate becomes exposed to UK IHT at 40% once you have been UK resident for 10 out of the previous 20 tax years — regardless of domicile, and regardless of where you are living or holding assets when you die.

The part that catches people out is the exit “tail.” Once you qualify as a UK Long-Term Resident under this test, leaving the UK does not immediately end your worldwide IHT exposure:

Someone who spent 20 years in the UK before moving to Dubai in 2026 remains exposed to UK IHT on their worldwide estate until roughly 2036. This is the closest thing the UK has to an exit tax in practice, even though it carries no such label, and it is the item most commonly missed by people who research only the income tax side of a move.

Trusts settled before 2025 carry their own transition risk: excluded property trusts that formerly gave non-doms permanent IHT protection lose that protection once the settlor becomes a Long-Term Resident under the new test, whether or not the settlor still benefits from the trust. Anyone with an offshore trust structure predating 2025 should have it reviewed specifically against this change.

The Temporary Non-Residence Trap

A separate and older anti-avoidance rule matters for anyone considering a short stint abroad rather than a permanent move. If you become non-UK resident and then return within 5 complete UK tax years, certain gains and income that arose while you were non-resident can be pulled back into UK tax on your return — the relief you thought you had secured by leaving is reversed retroactively.

This makes the length of a Dubai posting a genuine tax planning variable, not just a career one. A move intended to last three years behaves very differently under this rule than one intended to last six.

What Stays UK-Taxable After You Leave

Becoming non-UK resident does not end every UK tax obligation. Several things continue regardless of where you live:

• UK residential property gains. Non-resident Capital Gains Tax applies to UK residential property indefinitely — selling a UK home or buy-to-let after you have moved to Dubai still triggers a UK CGT charge, generally reported within 60 days of completion.
• UK rental income. Continues to be taxable and must be declared, typically under the Non-Resident Landlord Scheme, which affects how your letting agent withholds tax at source.
• Certain UK pension income and UK-source employment income. Some categories remain UK-taxable even after departure, depending on the specific arrangement.

None of this is an exit tax in the technical sense — it is the UK simply continuing to tax UK-source income the way most countries tax income arising within their borders. The mistake is assuming that leaving switches everything off.

UK Departure Checklist

• Confirm your residence position under the Statutory Residence Test, not by assumption. The “ties” framework — UK family, accommodation, work pattern, prior-year UK days — makes an ambiguous departure genuinely easy for HMRC to challenge.
• Establish whether split-year treatment applies, and identify the specific statutory case and departure date. Leaving partway through a tax year does not by itself make you non-resident for the whole year — split-year treatment, where it applies, taxes you as UK resident only up to your departure date.
• File form P85, or report the move via Self Assessment (SA109) if you already file a return. The P85 itself does not establish non-residence — the SRT does that — but it is the administrative step that triggers a departure-year refund review and adjusts your PAYE position.
• Send your P45 and claim any overpaid tax, which is common in a mid-year departure since your Personal Allowance was set for a full year of UK employment.
• Register any UK rental income under the Non-resident Landlord Scheme and keep filing UK Self Assessment for as long as you hold UK-source income.
• Review any pre-2025 offshore trust against the new Long-Term Resident rules.
• Calculate your specific IHT tail period before assuming your worldwide estate is clear, and map any planned asset disposals against the 5-year temporary non-residence clock.
• Decide on voluntary National Insurance. State Pension needs 35 qualifying years for the full New State Pension (roughly £12,548 a year at 2026/27 rates). Voluntary Class 2 NI for periods abroad ended on 6 April 2026; voluntary Class 3 now applies at £18.40 a week, roughly £957 for a full qualifying year — worth pricing against the pension gap it fills.

This is genuinely intricate legislation, still bedding in less than two years after the reform. Nothing here substitutes for advice from a UK-qualified tax adviser who can run your specific residence years, asset structure and departure date against the current rules.

What Changes on the Dubai Side

This half is simpler. The UAE levies no personal income tax on salary, freelance earnings, dividends, capital gains or inheritance, at any level — our guide to whether Dubai has income tax sets out exactly what is and is not taxed here. What the UAE side requires is proving your new residence to HMRC if it is ever questioned — a residence visa alone is not that proof.

The UK sits inside the UAE's double taxation treaty network. Our full guide to the UAE Tax Residency Certificate covers the 183-day and related tests, and the specific trap that gets certificates built on the weaker 90-day route rejected when presented under a treaty — worth building yours properly rather than as an afterthought, given how much the IHT tail alone is worth getting right.

If you are moving to set up a business rather than take employment, company formation and your own UAE residence visa typically come first. Our guide to business setup in Dubai covers that route, and the Dubai salary guide and cost of living in Dubai cover what an employment move actually looks like financially once you land. If you are also weighing the Indian side of a move, our companion guide to moving to Dubai from India covers RNOR status and the new deemed-residency rules.

Plan Your Move with Takween Advisory

The UK's reform did not add an exit tax \u2014 it replaced an indefinite domicile-based shelter with a residence-based system that has a long memory. The IHT tail is the item most people miss, and it can keep a worldwide estate inside the UK net for up to a decade after departure. Confirm your SRT position, calculate your specific tail, review any pre-2025 trust, and build a defensible UAE Tax Residency Certificate rather than assuming your visa does that job. Takween Advisory handles the UAE side of the move: residence and dependant visa services, corporate tax registration and planning. Book a free consultation to map the UAE half of your move — for the UK side, this reflects the position as published and is general information, not personalised tax advice; confirm your specific position with a UK-qualified adviser before relying on it.
