Is there a UK exit tax when you move to Dubai?

“Exit tax” is one of those phrases that does the rounds whenever the subject of leaving the UK comes up — often with a sense of urgency attached. The accurate position is calmer than the headlines suggest, and it’s worth understanding before you make decisions based on a rumour.
The current position: no general UK exit tax
The UK does not levy a general exit tax. Some countries — Canada, Australia, and the US expatriation regime among them — treat emigration as a deemed disposal: the day you leave, you’re taxed as if you’d sold your assets at market value, even though you still hold them. The UK does not do this.
So if you move to Dubai still holding shares, crypto, or your company, the act of leaving doesn’t crystallise a capital gains tax (CGT) bill. Tax arises when you actually sell — and once you’re genuinely non-resident, gains on most assets that aren’t UK land or property fall outside UK CGT altogether.
That’s the durable fact to hold on to. The complications sit around it.
What actually catches people: the temporary non-residence rule
The real trap isn’t an exit tax — it’s the temporary non-residence rule. If you leave the UK and return within five complete tax years, certain gains you realised while abroad can be taxed in the year you come back, as though you never left.
It exists precisely to stop people moving abroad briefly, selling an asset free of UK CGT, then coming home. A short stint in Dubai timed around a sale is exactly the pattern it’s built to catch. A genuine, settled move is treated quite differently from a five-year round trip — but you have to actually be making the former.
This is why “I’ll move to Dubai and sell” is rarely the whole plan. Becoming non-resident under the Statutory Residence Test is step one; staying non-resident long enough is step two.
What’s taxed when you leave — and what isn’t
| Asset / situation | UK CGT position once non-resident |
|---|---|
| Non-UK assets (most shares, crypto, overseas holdings) | Generally outside UK CGT — unless you return within five years |
| Sale of your UK company shares after a genuine, lasting move | Generally outside UK CGT once non-resident, subject to the five-year rule |
| UK residential or commercial property | Stays within UK CGT (Non-Resident CGT); report within 60 days of completion |
| Any disposal made before you become non-resident | Taxed as a normal UK-resident disposal |
The line that matters most is the timing of a disposal relative to your departure date — and relative to that five-year window on the way back.
The proposed exit tax — what’s been floated, and where it stands
Periodically, an actual UK exit tax gets proposed: a charge on the unrealised gains of people leaving the country, bringing the UK closer to the deemed-disposal model used elsewhere. It tends to resurface around Budgets and in think-tank papers, usually aimed at founders and wealthy individuals relocating before a sale.
At the time of writing, it is not law. It’s a proposal that has been discussed, not a charge that has been enacted. Proposals of this kind have come and gone before without making it onto the statute book.
The sensible posture is to watch it, not to be stampeded by it. Uprooting your life on the strength of a rumour — in either direction — is rarely good planning. If an exit tax ever does arrive, the detail (what it applies to, any thresholds, transitional rules) will matter enormously, and that’s the point at which to take advice on your specific position.
What this means if you’re selling a business
For a founder planning to exit a UK company, the current rules reward getting the sequence right rather than rushing:
- Become genuinely non-resident under the SRT before the disposal.
- Plan to stay non-resident for at least five complete tax years, so the temporary non-residence rule doesn’t reel the gain back in.
- Remember that getting your departure year right is where a lot of the value — and a lot of the common mistakes — sit.
Where this gets genuinely personal is in the detail of your shareholding, your timeline, and your ties to the UK. Whether moving to Dubai is worth it on the tax alone depends entirely on those specifics. The headline — no exit tax today, but a five-year rule that bites — is the same for everyone; how it applies to you isn’t.
