What happens to your ISA's tax-free status if you move overseas?
An ISA survives a move abroad: you keep the account, the investments and the UK tax exemption on income and gains inside it. What stops is your ability to pay in. And the exemption is a UK one — the country you move to applies its own rules, and many of them tax an ISA like any other account.
- You keep it: the account continues and remains free of UK tax on income and gains.
- You cannot add: subscriptions stop once you are no longer UK resident.
- The exception: Crown employees serving overseas and their spouses can continue subscribing.
- The catch: the exemption is UK-only; your country of residence may tax the account.
01 What continues and what stops
The ISA itself continues. The investments stay where they are, the wrapper remains intact, and income and gains inside it stay free of UK Income Tax and Capital Gains Tax for as long as you hold it. Nothing has to be sold and nothing has to be moved.
What stops is subscribing. You cannot pay into an ISA for any tax year in which you are not UK resident, and you must tell your provider when you stop being resident. Subscriptions made while non-resident are invalid and have to be unwound.
The exception covers Crown employees serving overseas — diplomatic and armed forces personnel — and their spouses or civil partners, who can continue to subscribe.

02 The exemption does not travel
An ISA is a creature of UK tax law and other countries are not obliged to recognise it. Many treat it as an ordinary investment account and tax the income and gains under their own rules, which can mean an annual charge on growth that the UK never levied.
The United States is the most demanding case: an ISA is not a recognised tax-advantaged account there, and holdings in non-US funds can attract punitive reporting and tax treatment for US taxpayers. Several EU countries tax ISA income annually as investment income.
So the useful question before a move is not whether you can keep the ISA but whether you should. Where the destination taxes it annually, the wrapper is doing nothing and the account has become an ordinary one with UK reporting attached — which is the same calculation as choosing the wrapper in the first place, run against a different tax system.
Shows: the annual tax on ISA growth if the country you move to taxes it, against the nil charge in the UK. Ignores: your actual destination's rules, treaty relief, currency movements, and reporting costs.
On the defaults above, the worked example shows £1,350. The UK charges nothing on this growth; the country of residence would take £1,350 a year, which is what the wrapper stops being worth.

03 On returning, and on death
Coming back restores the ability to subscribe from the tax year in which you become resident again. The account has continued throughout, so nothing has to be rebuilt — which is a strong argument against closing an ISA on departure.
On death, a surviving spouse or civil partner can claim an additional permitted subscription equal to the value of the ISA, over and above their own allowance. That entitlement is unaffected by the deceased having lived abroad, though the survivor has to be able to subscribe in their own right.
For anyone planning to return, keeping the account open and unfunded is almost always better than closing it, because the allowance cannot be backdated and the wrapper cannot be recreated.

Keep the account and stop paying in — that part is easy. The part that catches people is assuming the tax exemption comes with them. It does not. An ISA is a UK construct and most countries have no reason to honour it, so someone retiring to a country that taxes investment income annually now holds a perfectly ordinary account with a UK label on it. Find out what your destination does with it before you go, because the answer sometimes changes whether the money should be in an ISA or a pension in the first place.
FAQ
Can I keep paying into my ISA if I move abroad?
No, not for any tax year in which you are not UK resident. You must tell your provider when you stop being resident, and subscriptions made while non-resident are invalid. Crown employees serving overseas and their spouses are the exception.
Does my ISA stay tax free abroad?
In the UK, yes. In your country of residence, only if that country recognises it — and most do not. Several tax the income and gains annually under their own rules, which removes the point of the wrapper while you live there.
Should I close my ISA before leaving?
Usually not. The account continues, the wrapper cannot be recreated, and the ability to subscribe returns automatically if you become UK resident again. Closing it converts a preserved allowance into an ordinary account for no gain.
