What Happens to My ISA if I Move Abroad? (UK 2026/27)

If you move abroad and stop being UK resident for tax purposes, your existing UK ISA stays open and the interest, dividends and gains inside it stay tax-free under UK rules. You cannot pay new money into it from the tax year after you leave, but the wrapper, the balance and any investments inside it are preserved.

That sounds simple. In practice there are several wrinkles — the tax year you leave matters, the country you move to matters, and the rules for transferring or topping up differ across cash, stocks & shares and Lifetime ISAs. This is a walk through each one, using 2026/27 tax-year rules.

Can I keep my ISA if I leave the UK?

Yes. Once an ISA has been opened by a UK resident and properly funded, the provider does not have to close it when you become non-resident. HMRC’s long-standing position is that the wrapper is preserved — interest, dividends and capital gains inside the ISA continue to be free of UK tax for as long as the account exists.

You must tell your ISA provider about the change in residence. They have an obligation under HMRC’s ISA manager rules to record that you are no longer eligible to subscribe and to stop accepting new subscriptions from you.

The relevant authority is HMRC’s ISA manager guidance on overseas customers.

Can I pay new money into my ISA while I live abroad?

Generally no. To subscribe to an ISA in a given tax year, you must be UK resident for tax purposes in that year, or be a Crown employee serving overseas (or the spouse / civil partner of one).

The mechanics work like this:

• You can keep contributing in the tax year you leave the UK, up until you become non-resident under the Statutory Residence Test.
• From the next full tax year onward, no contributions are allowed.
• Tax years run 6 April to 5 April.
• If you return to UK residence in a later tax year, you can start contributing again from that tax year onward — the wrapper has been waiting for you.

The Statutory Residence Test (SRT) is set out in HMRC’s Residence guidance (RDR3). It is not a simple count of days — connections to the UK (work, family, accommodation) all interact with day-counts.

Do I still get the tax-free benefit while I'm abroad?

You keep UK tax-free treatment for as long as the ISA exists.

But — and this matters — moving abroad usually exposes you to the tax rules of the country you move to, and many countries do not recognise the UK ISA wrapper. They treat the ISA as a normal taxable investment account.

A few examples that come up a lot:

• United States — the IRS taxes ISA income and gains. Stocks & shares ISAs holding non-US-domiciled funds can also create unexpectedly heavy reporting and tax burdens under PFIC rules.
• Australia, Canada, New Zealand — generally tax ISA income and gains as you would any other investment account.
• EU countries with worldwide-income taxation — typically tax ISA income, sometimes with credit for any UK tax that would have been paid.

Always check the local tax position with a qualified adviser in your destination country before moving. The ISA does not escape local tax just because the UK doesn’t tax it.

Can I withdraw money from my ISA while abroad?

Yes — there’s no UK restriction on withdrawing from a cash or stocks & shares ISA from overseas. The provider may require additional identity checks, may not be able to send funds to certain countries, and some providers ask non-resident customers to leave the platform entirely.

In practice:

• Cash ISA — withdraw to your nominated UK bank account, then transfer abroad.
• Stocks & shares ISA — sell the investments inside the wrapper, withdraw the cash, transfer.
• Lifetime ISA — withdrawals for purposes other than first-home or age-60+ retirement trigger a 25% penalty on the withdrawn amount. Moving abroad doesn’t change that.

If your provider can’t serve non-residents (some can’t), you may need to transfer the ISA to a different UK provider that does. This must be done via the formal ISA transfer process — never by withdrawing and re-subscribing, which would lose the wrapper.

What if I’m on a UK visa rather than emigrating?

If you’re on a UK visa and meeting the Statutory Residence Test, you are typically UK resident for tax purposes and can subscribe normally — the visa itself doesn’t block ISA eligibility. If you then leave the UK and become non-resident, the rules above apply.

The trickier case is when you remain non-domiciled but UK resident. Until 6 April 2025, the remittance basis affected how foreign income was taxed but didn’t affect ISA eligibility. From April 2025, the non-dom regime has been replaced with a 4-year FIG (Foreign Income and Gains) regime — see HMRC’s non-dom transitional guidance. [VERIFY: confirm current detail of FIG transitional rules with HMRC before relying on this.]

Worked example: leaving the UK partway through the tax year

Anna becomes non-resident from 1 September 2025. By that point in the 2026/27 tax year she has already paid £8,000 into her stocks & shares ISA.

• For 2026/27: she is UK resident for part of the year. HMRC accepts the £8,000 of subscriptions made while she was resident. She can subscribe up to a further £12,000 between 6 April 2025 and 31 August 2025 if she chooses — but not after she becomes non-resident.
• For 2026/27: she is non-resident for the whole year. No subscriptions allowed.
• Existing pot: continues to grow tax-free under UK rules. The country she has moved to may tax the income.
• If she returns to UK residence in, say, 2028/29: she can subscribe to ISAs again from that year onward, with the standard £20,000 allowance.
