How does your ISA affect you when living abroad?

The key point: an ISA can stay tax-free in the UK, but that does not mean another country will treat it as tax-free.

What changes from April 2027?

The total ISA allowance remains £20,000 a year. From 6 April 2027, people under 65 can put up to £12,000 a year into a cash ISA. The rest can go into other ISAs, including a stocks and shares ISA. People aged 65 or over can still use the full £20,000 cash allowance. Money already in an ISA is not affected.

If you move abroad

If you stop being a UK tax resident, you normally cannot add new money to your ISA, but you can keep the ISA you already have. Montfort research has identified 25 countries where the UK tax-free status of an Individual Savings Account may not be recognised in the same way. Local tax may apply to interest, dividends or investment gains.

UK pensions can face similar issues

Moving abroad can also change how a UK pension is taxed. The answer may depend on the pension, how money is taken, local law and any tax treaty with the UK. Review pensions and ISAs before moving.
