Can Expats Keep or Use a UK ISA? The Rules

Many UK expats ask what happens to their ISA when they move abroad. The short answer is that you can usually keep an ISA you already hold, but you cannot normally keep paying into it, and the tax-free status may not carry over to your new country. This guide sets out the rules and what to do before you leave.

This guide is general information, not tax advice. Check the current rules with your ISA provider and a tax adviser who knows the country you move to.

The short answer

You do not have to close an ISA when you move abroad.
Once you stop being UK resident, you can generally not pay in new money, with limited exceptions.
An existing ISA keeps its UK tax benefits, but the country where you live may tax the interest, income or gains.
Some providers will not keep serving customers who live in certain countries, so check yours.

Who can open and pay into an ISA

GOV.UK says you must be 18 or over to open an ISA, and for a Lifetime ISA you must also be under 40. You must be resident in the UK, with an exception for Crown employees serving overseas and paid from UK public revenue, and their spouses or civil partners. The annual allowance is £20,000 in the 2026 to 2027 tax year, which you can save in one account or several, and up to £4,000 of it can go into a Lifetime ISA.

If you do not meet the residence condition, you cannot normally subscribe. That is why a move abroad matters.

What happens to your existing ISA

Guidance for ISA managers says an ISA does not need to be closed when the holder stops being UK resident, and it keeps its tax benefits. In practice:

the money stays in the ISA and can grow tax-free for UK purposes
you must tell your ISA provider when you stop meeting the residence rules
the provider may restrict some services for customers abroad
you can usually still withdraw or transfer, subject to the provider’s terms

The UK tax treatment is only half the picture. The country where you live decides how it taxes residents.

Paying in after you move

Once you are not UK resident, new ordinary subscriptions are generally not allowed. Rules for managers say that subscriptions made while non-resident, with related income and growth, may have to be removed, apart from a short list of permitted exceptions.

A few points to bear in mind:

The year you leave. Whether you can still pay in during the tax year you leave depends on your residence status for that year and on the provider’s approach. Ask the provider in advance, and do not pay in on the assumption it will be accepted.
Declare your status. Providers rely on your declaration of residence. Tell them honestly when it changes.
Returning to the UK. If you return and become UK resident again, you can make a new declaration of residence and your existing account can be used again, subject to the provider.
Junior ISAs. There is a separate rule for children who become non-resident, so check the Junior ISA terms with the provider.

Lifetime ISAs

A Lifetime ISA adds a government bonus and has a charge for early withdrawals. Moneybox, a UK provider, says the funds can only be used for a first home in the UK or for retirement, and that using them to buy a first home abroad triggers the 25 per cent government penalty. Rules for withdrawals are strict, so check the position with your provider before you move or withdraw.

How an ISA is taxed where you live

A UK ISA is tax-free for UK purposes. Other countries have their own rules, and many do not recognise ISA status. Typical results include:

interest, dividends or gains in the ISA may be taxable in the country where you live
you may need to report the ISA on a local tax return
some countries may treat the ISA as part of your wealth for wealth-tax purposes
reporting rules can apply to foreign accounts

Because the rules vary so much, we cannot give a general answer. Take advice from a tax adviser who knows the country you are moving to, and ask before you move, not after.

Some providers will not keep you

Providers decide whom they will serve. Some cannot or will not hold accounts for customers in certain countries, and the United States in particular is often a problem because of US tax and reporting rules. If your provider closes your account or restricts it, you may need to withdraw, transfer or sell. Check the position before you move so that you can plan the timing.

Your options before you leave

Keep the ISA. This suits people who expect to return to the UK and whose new country does not tax it heavily. You still need to tell the provider.
Withdraw and use the money. If the tax where you will live would be costly, taking the money out before you leave may be sensible, though you lose the tax-free wrapper for that money.
Use the allowance first. If you are still UK resident, consider using the current year’s allowance before you go, if it fits your plans.
Transfer. Some providers may allow a transfer to another provider, but ask whether either will accept a customer who lives abroad.
Move to another tax-efficient route. Depending on where you live, a local scheme or a different product may be better. Take advice.

If you hold stocks and shares inside the ISA, ask what happens to currency conversion and to dealing if you become non-resident.

A worked example

This example is illustrative.

A couple hold £60,000 in stocks and shares ISAs and plan to move to Spain for five years. Before they go, they ask the provider whether they can keep the accounts, and they get written confirmation. They tell the provider their new residence status, and they stop paying in.

They then ask a tax adviser about Spain. The adviser explains that the ISA gains may be taxable there and that the accounts must be reported. The couple decide to keep the ISAs because they plan to return, accepting the local tax and reporting. If they had decided otherwise, they could have sold the investments before leaving, while still UK resident, and used the cash.

Common mistakes

Paying in after becoming non-resident without checking.
Not telling the provider about a move.
Assuming UK tax-free means tax-free everywhere.
Forgetting local reporting duties on foreign accounts.
Waiting until after the move to ask the provider what is allowed.

Frequently asked questions

Can I keep my ISA if I move abroad?

Yes, in most cases. You do not have to close it, but you must tell the provider and you may not be able to pay in.

Can I pay into an ISA as an expat?

Not normally. Paying in generally requires UK residence, with limited exceptions such as Crown employees serving overseas.

Is my ISA still tax-free abroad?

It stays tax-free for UK purposes, but the country where you live may tax it and require you to report it.

What happens to my Lifetime ISA if I move abroad?

You can usually keep it, but the funds can only be used for a first UK home or retirement. Other withdrawals carry a penalty, so check with the provider.

Can I open a new ISA while living abroad?

Generally no, because opening one requires UK residence.
