Is there a UK exit tax? No, but 3 things act like one
“Exit tax” comes up in almost every first call we have with a founder planning a sale. The position as at October 2026 is calmer than the headlines: the UK has no exit tax for people who leave. What it does have is three rules that behave like one if you get the timing wrong, plus a real exit charge for companies.
Is there an exit tax in the UK?
No, not for individuals. Some countries treat emigration as a deemed disposal: on the day you leave, you are taxed as if you had sold your assets at market value. Canada works this way, and the US has an expatriation tax for people who give up citizenship. The UK does not.
If you move to Dubai still holding shares, crypto or your company, leaving does not crystallise a capital gains tax (CGT) bill. Tax arises when you sell. Once you are non-resident under the Statutory Residence Test, gains on most assets other than UK land and property fall outside UK CGT.
Do you pay tax when you leave the UK?
On the act of leaving, no. On the year you leave, yes: you stay UK resident until your departure date (with split-year treatment) or for the whole tax year (without it), and anything you sell before you become non-resident is taxed as a normal UK disposal. As at October 2026, UK CGT for individuals is 18% within the basic-rate band and 24% above it (GOV.UK). The free split-year calculator shows how your departure year divides.
The three things that act like an exit tax
| Rule | What it catches | How long it lasts |
|---|---|---|
| Temporary non-residence | Gains (and some income) you realise abroad on assets you owned before leaving | If you return within five years |
| UK land and property | Gains on UK homes, buy-to-lets and commercial property | For as long as you own it |
| The inheritance tax tail | Your worldwide estate, for long-term UK residents | 3 to 10 tax years after you leave |
1. The five-year rule (temporary non-residence)
This is the rule that catches people. If you were UK resident for at least four of the seven tax years before you left, and you come back within five years, gains you realised while abroad on assets you owned before departure are taxed in the tax year you return. HMRC’s Statutory Residence Test guidance (RDR3) covers how residence and the years before departure are counted.
It also reaches some income: large dividends from a company you control, paid while you are abroad out of profits built up before you left, can be taxed on your return in the same way. The rule exists to stop the short round trip: leave, sell, come home. A settled move that lasts longer than five years is outside it.
2. UK property stays in UK CGT
UK land and property stay within UK CGT wherever you live. Sell a UK flat or a buy-to-let from Dubai and you must report it to HMRC within 60 days of completion and pay any tax due (GOV.UK: CGT for non-residents). For residential property you can usually measure the gain from its value in April 2015, so a long-held home may carry less taxable gain than you expect. If you are letting it out while you are away, the Non-Resident Landlord Scheme covers the rent.
3. The inheritance tax tail
Inheritance tax runs on a longer clock than income tax or CGT. Since 6 April 2025 it depends on whether you are a long-term UK resident: UK resident in at least 10 of the previous 20 tax years. If you are, your worldwide estate stays within UK inheritance tax for a period after you leave: 3 tax years if you had 10 to 13 years of UK residence, plus one year for each extra year, up to 10 tax years (reached at 20 years of residence) (GOV.UK). From 6 April 2027 most unused pension funds also come into the estate.
Worked examples
These are illustrations using the rates above, not advice. Your own numbers depend on your base cost, reliefs and income.
A founder sells two years after moving. She leaves the UK in September 2026 after 20 years of UK residence, becomes non-resident, and sells her UK company shares in 2028 for a £1,000,000 gain.
- She stays in Dubai: no UK CGT on the sale.
- She moves back in 2030, within five years: the £1,000,000 gain is taxed in the year she returns. At 24% that is £240,000, less any relief she qualifies for, such as Business Asset Disposal Relief at 18% on a qualifying gain.
- She sells in August 2026, a month before leaving: the gain is taxed as a UK-resident disposal, whatever she does next.
A landlord sells his London flat from Dubai. He has owned it since 2010 and lets it out after he moves. When he sells in 2028, the gain is in UK CGT. He reports within 60 days and can usually measure the gain from the April 2015 value rather than the 2010 price.
A lifelong UK resident moves at 45. He has well over 20 years of UK residence, so his inheritance tax tail is the full 10 tax years. Moving to Dubai protects his income from UK tax almost at once; his worldwide estate stays in the UK net until the tail runs out. Someone with 15 years of UK residence would have a 5-year tail.
Is the UK bringing in an exit tax?
Periodically, a UK exit tax gets proposed: a charge on the unrealised gains of people leaving, closer to the deemed-disposal model used elsewhere. It tends to resurface around Budgets and in think-tank papers, usually aimed at founders who relocate before a sale.
As at October 2026 it is not law. The next fiscal event is the Autumn Budget on 28 October 2026, and we will update this page if it changes anything. Until then, plan on the rules that exist. If a charge ever arrives, the detail (who it covers, any threshold, the start date, transitional rules) will decide whether it touches you, and that is the point to review your position.
UK exit tax for companies
Companies are different. If a UK company stops being UK resident, for example because its directors move to Dubai and start running it from there, it is treated as disposing of its assets at market value when it leaves. That can create a corporation tax charge on goodwill, intellectual property and investments. It is one reason founders usually form a new UAE company rather than migrate the UK one, and why a UK company run from Dubai needs care: our guide to central management and control explains where a company is resident, and running a UK business from Dubai covers the options.
What this means if you are selling a business
- Become non-resident under the Statutory Residence Test before the sale, and get your departure year right.
- Plan to stay non-resident for more than five years.
- Keep your UK days under your limit: the day allowance calculator works it out from your ties.
- Treat UK property and your estate as separate plans with their own timelines.
- Decide whether the move is worth it on tax alone, and read the tax angle on selling before you go.

Questions people ask
Is there an exit tax in the UK?
Not for individuals, as at October 2026. The UK does not treat emigration as a sale of your assets, so leaving does not create a capital gains tax bill on shares, crypto or a business you still own. Tax arises when you sell something, and once you are non-resident most gains on non-UK assets fall outside UK capital gains tax, subject to the five-year temporary non-residence rule.
Will the UK charge exit tax on my gains if I move to Dubai?
No. The catch is the temporary non-residence rule: sell assets while abroad and return to the UK within five years, and gains on assets you owned before leaving can be taxed in the year you come back. UK land and property also stay within UK capital gains tax while you are non-resident.
What is the temporary non-residence rule?
If you were UK resident for at least four of the seven tax years before you left and you return within five years, gains you realised while abroad on assets you owned before leaving are taxed in the tax year you come back, as if you had never gone. Some income, such as large dividends from your own company paid out of profits built up before you left, is caught the same way.
Is the UK bringing in an exit tax?
As at October 2026, no exit tax for individuals is law. A charge on the unrealised gains of people leaving has been floated by commentators and think tanks and has resurfaced around past Budgets. The next fiscal event is the Autumn Budget on 28 October 2026. If anything changes, the detail, such as who it applies to, thresholds and start dates, will decide whether it affects you.
Does leaving the UK trigger tax on my investments?
Not by itself. Tax arises when you dispose of an asset. Once you are non-resident under the Statutory Residence Test, gains on most non-UK assets fall outside UK capital gains tax, provided you stay non-resident for more than five years.
I plan to sell my company after moving to Dubai. When am I free of UK capital gains tax?
Broadly, once you are non-UK resident under the Statutory Residence Test, you sell while non-resident, and you stay non-resident for more than five years. Sell before you become non-resident, or come back within the five-year window, and the gain is taxed in the UK. The order of departure and sale is the part to plan.
Does UK property still get taxed after I leave?
Yes. UK land and property stay within UK capital gains tax wherever you live. If you sell UK property after moving to Dubai, you report the sale to HMRC within 60 days of completion and pay any tax due, even if there is no gain to tax.
Is there an exit charge if I move my UK company to Dubai?
For companies, yes. If a UK company stops being UK resident, for example because its management moves to Dubai, it is treated as selling its assets at market value on the day it leaves, which can create a corporation tax charge. That is why most founders form a new UAE company rather than migrate the UK one.
