It’s a question we get asked more often than you might think: “Can I avoid CGT by moving abroad?”
The short answer is: yes, in some cases, it’s legally possible. But – and this is a big but – it’s complicated, it’s not a quick fix, and HMRC have rules specifically designed to stop people gaming the system.
Here’s what you need to know.
The basics
If you become a non-UK resident for tax purposes and then sell certain assets while you’re abroad, you may not have to pay UK Capital Gains Tax on the gain.
But, and here’s where it gets tricky, you need to meet specific conditions which we’ll go into now. Get it wrong, and you could end up with a tax bill anyway.
The five-year rule
This is the big one.
To avoid CGT by moving abroad on assets you owned before you left, you need to remain a non-UK resident for at least five full UK tax years. If you return to the UK within that period, the temporary non-residence rules kick in, and the gain gets taxed in the year you come back.
So if you’re thinking of a quick hop across the Channel, selling your shares, and coming home…think again!
Tax residency matters
You don’t become non-resident just by leaving the country. Your residency status is determined by the Statutory Residence Test, which looks at things like:
- How many days you spend in the UK
- Whether you have a home here
- Whether you work here
- Your family ties
You need to become non-resident before you sell the asset. Not after. Timing matters.

What about UK property?
Here’s the catch: you can’t avoid CGT by moving abroad on UK property.
Gains from the sale of UK land or property – residential or commercial – are always subject to UK Capital Gains Tax, even if you’re non-resident. And you need to report the disposal to HMRC within 60 days.
So if your main asset is a UK property, moving abroad won’t help you.
What about shares and investments?
This is where the strategy can work.
Gains on assets like shares, investments, and other non-UK property can potentially be exempt from UK CGT if you’re genuinely non-resident and meet the five-year rule.
Assets you acquire after you become non-resident aren’t caught by the temporary non-residence rules either – so if you return within five years, gains on those assets won’t be taxed in the UK.
Don’t forget the new country (and their tax laws)
Moving abroad doesn’t mean you escape tax altogether. Your new country of residence will have its own tax rules, and you may well be liable for CGT there.
The UK has double taxation agreements with many countries to prevent you being taxed twice on the same gain. But you need to understand the rules in both jurisdictions before you make any decisions.

Does it actually work in practice?
This is the question people forget to ask.
Moving abroad for five full tax years probably means being away for a bit longer than five years in practice. And depending on your circumstances, you may only be able to return to the UK for as few as 15 days per year (or as many as 91) without triggering residence.
Living, working, schooling, socialising, family left behind – these all matter. For some people, it’s a genuine lifestyle change. For others, it’s just not practical.
When the five-year rule doesn’t apply
There are two main exceptions:
- If you weren’t a UK resident for at least four of the seven years before you left, the five-year rule doesn’t apply to you.
- Assets you acquire after leaving the UK aren’t subject to the temporary non-residence rules, so gains on those assets won’t be clawed back if you return early.
Professional advice is essential!
Can you avoid CGT by moving abroad? Yes, in some cases. It is possible to legally avoid UK Capital Gains Tax on certain assets by moving abroad and becoming a non-resident for tax purposes. Provided specific conditions are met and you stay non-resident for at least five full UK tax years.
However, this is a complex area requiring careful planning, and a clear understanding of the rules. HMRC scrutinises cases where people appear to be moving abroad purely for tax reasons while keeping significant ties to the UK – so this isn’t something to wing. You should always get professional advice from a UK tax specialist (like JVCA the friendly accountants) before making any decisions.
