Moving to Dubai: the UK tax that follows you

Dubai is the first destination almost everyone names, and the headline is true. The UAE has no personal income tax on salary, dividends or gains for individuals. The part that gets left out is everything the UK does on the way out, and it is the expensive part.

Leaving is a test, not a decision

You do not become non resident by deciding to be. You become non resident by satisfying the Statutory Residence Test, which counts days and connections.

The automatic limits, if you were UK resident in any of the previous three tax years:

• Fewer than 16 UK days: automatically non resident
• 183 or more UK days: automatically resident, with no exceptions

In between, it comes down to ties. Family, accommodation, work, the 90 day tie and the country tie. As a leaver, 16 to 45 days needs four or more ties to make you resident, 46 to 90 days needs three, 91 to 120 needs two, and 121 to 182 needs only one.

That last line is the one that catches people. Keep a house available in the UK and visit for four months and a single tie makes you resident again. The house alone can be that tie.

The full time work abroad route

This is the cleanest exit for most working directors. Average 35 hours a week or more overseas, no break of 31 days or more, fewer than 91 UK days in the tax year, and fewer than 31 of those days with more than three hours of work in the UK.

It is a real test with real record keeping behind it. Keep the flights, the calendar and the timesheets, because HMRC asks for evidence and does not accept recollection.

The inheritance tax tail

This is the piece almost nobody prices in. Since 6 April 2025 the UK uses a residence based inheritance tax regime. If you have been UK resident for at least 10 of the previous 20 tax years, you are a Long Term Resident and your entire worldwide estate stays in the UK inheritance tax net at 40%.

Leaving does not switch that off on departure. It runs off on a sliding scale:

• Fewer than 10 years of UK residence: no tail at all
• 10 to 13 years: a three year tail
• Each further year adds one, so 15 years gives a five year tail
• 20 years or more: the full ten year tail

So a director who has lived in Britain their whole adult life and moves to Dubai is still inside UK inheritance tax on their worldwide estate for a decade.

The UAE is not tax free either

Personal income tax is zero. Business tax is not. The UAE introduced 9% federal corporate tax on business profits above AED 375,000 in June 2023, and an individual running a business in the UAE with turnover over AED 1 million falls inside it.

Small Business Relief, which has let smaller operations elect to have no taxable income, ends for tax periods ending on or before 31 December 2026. If your plan was built on that relief, the plan has an expiry date on it.

Free zone 0% is conditional rather than automatic. It requires qualifying income, real substance and the right activity, and non qualifying income is taxed at 9%.

The order you do things in

The most expensive mistakes here are sequencing mistakes. Selling a company after you leave, but not late enough, can pull the gain back under the temporary non residence rules. Restructuring after the move is usually harder and dearer than restructuring before it. Keeping a UK home for sentiment can cost you the residence position you moved for.

None of that argues against going. It argues for doing it in the right order.

If you are seriously considering it

Leaving is a structuring decision, not a filing decision, and it is the one area where the order you do things in changes the tax more than anything else. That work sits with CT Private Office rather than a monthly accountancy package.
