Readers often want a single sentence: ‘your ISA is fine’ or ‘you must cash it in’. Neither sentence is safe. The UK rules on who may subscribe are one issue. The tax rules of the country you move to are another. The provider’s willingness to keep a non-resident as a customer is a third.
What the wrapper does, and where it stops
Inside the UK, an ISA shelters eligible savings and investments from UK income tax and capital gains tax, within the subscription rules for that year. That shelter is a feature of UK tax law. A country you become resident in can tax dividends, interest or gains arising in the ISA even though the UK does not. Some countries look through the wrapper entirely.
Paying more money in
In general, you need to be UK resident to subscribe to an ISA. There are specific rules for the tax year of departure, and there have long been particular provisions for some people, such as certain Crown employees. Those exceptions are narrow. If you are unsure whether you are still UK resident for the year in question, do not rely on a day-count app alone.
Existing ISA investments are a different question from new subscriptions. Many people leave holdings where they are. Whether that is sensible depends on the new country’s tax treatment, on charges, and on whether the provider accepts your new address.
The country you are moving to
Tax authorities outside the UK do not have a standard approach to ISAs. Some may tax income as it arises. Some may tax gains when you sell. A double-tax treaty might be relevant, or it might not reach this kind of wrapper. This is exactly the sort of point a cross-border tax adviser is for.
- Confirm your UK residence position for the year of the move.
- Ask the ISA provider about non-resident customers.
- Ask a local adviser how the new country treats the account.
- Keep statements showing value on the date you leave.
What not to rush
Cashing in an ISA, moving it into an offshore bond, or transferring the investments to a spouse are all real decisions with costs and tax consequences. They can be right. They are not a default step for everyone who has booked a flight. If someone contacts you offering to ‘unlock’ the ISA because you are moving, treat that as a sales conversation and take independent advice first.
