UK tax advice for moving to Dubai

A UAE formation agent cannot do this part. It runs on HMRC rules: the day counts and ties of the Statutory Residence Test, the split-year cases, the temporary non-residence rule and the inheritance tax tail. The regulated advice comes from a UK Chartered Tax Adviser we work with.

Six to twelve months before you leave is the right time to start. If you have already gone, the Clean Break Review checks what you did and what still needs filing.

When your UK tax stops

HMRC decides your residence one tax year at a time, under the Statutory Residence Test (HMRC guidance RDR3). The test runs in order: automatic overseas tests, then automatic UK tests, then a sufficient ties test that weighs your UK days against the connections you keep: family, a home, work, and time spent here in earlier years.

In the year you leave, split-year treatment can divide the tax year into a UK-resident part and a non-resident part. It is not automatic. You have to fit one of HMRC's cases, such as starting full-time work overseas or leaving to live abroad, and the facts on the day you go decide which one. People lose it by keeping a UK home available, by working too many UK days, or by coming back for a long summer in the first year.

What is at stake, in figures

As at October 2026, UK income tax for 2026-27 runs at 20% on income from £12,571 to £50,270, 40% up to £125,140 and 45% above that, with the personal allowance withdrawn between £100,000 and £125,140 (GOV.UK). Dividends are taxed at 10.75%, 35.75% and 39.35% after a £500 allowance (GOV.UK). Capital gains are taxed at 18% within the basic-rate band and 24% above it (GOV.UK).

The UAE has no personal income tax, so a clean departure year is the difference between those rates and nothing on your Dubai earnings. A departure year that fails can leave a full year of worldwide income in the UK net. Run your own numbers in the UK vs Dubai take-home calculator.

Selling a business or property around the move

Order matters more than anything else here. Sell a UK business while you are still UK resident and the gain is taxed in the UK: Business Asset Disposal Relief, where it applies, gives 18% for disposals on or after 6 April 2026, and gains outside the relief are taxed at 24% for higher and additional rate taxpayers (GOV.UK).

Leaving first changes the picture, with two catches. UK residential property stays within UK capital gains tax wherever you live. And the temporary non-residence rule can pull gains back into UK tax if you return to live in the UK within five years (the rule explained). We map the sale, the move and the date of any return together. More in selling your UK business before Dubai.

What stays taxable in the UK after you leave

• Rent from UK property, under the Non-Resident Landlord Scheme (how it works)
• Some UK pensions, depending on the type and the UK-UAE treaty (pensions after the move)
• Gains on UK property, whatever your residence
• Inheritance tax, for long-term UK residents

Inheritance tax moved off domicile from 6 April 2025. You are a long-term UK resident if you were UK resident in at least 10 of the previous 20 tax years. After you leave, the tail runs for 3 tax years if you were resident for 10 to 13 years, plus one year for each extra year, up to 10 tax years (GOV.UK). From 6 April 2027 most unused pension funds come into the estate as well. For someone who has lived in the UK all their life, that means a decade of planning after the move, and we build it into the plan.

The treaty, the P85 and the paperwork

The UK and the UAE have a double taxation agreement (GOV.UK). Because the UAE has no personal income tax, it acts as the backstop: it matters for pensions and for anyone resident in both countries under domestic rules. A UAE Tax Residency Certificate is how you prove the UAE side.

The P85 tells HMRC you have left and can recover tax overpaid on your salary in the departure year. It does not make you non-resident. Most leavers also file a final Self Assessment return to claim split-year treatment, and anyone with UK income keeps filing after that.

How it works

1. Assess

   A call and a short questionnaire on your days, ties, income, assets and plans. We tell you where you would land under the test today.

   Typical timing: Week 1

2. Plan

   A UK Chartered Tax Adviser reviews the position and we agree the departure date, the split-year case and the order of any sale.

   Typical timing: Ideally 6 to 12 months before you leave

3. Leave

   P85, notices to banks and pension providers, NRLS registration if you let property, and a day-count log from day one.

   Typical timing: The month you go

4. File

   The final return for the departure year, claiming split-year treatment.

   Typical timing: After the tax year ends, by the normal Self Assessment deadline

5. Keep it clean

   An annual check of UK days, ties and UK income for the years the tests and the tail still apply.

   Typical timing: Each tax year
