A tax-advantaged ISA is part of a long-term savings and investment strategy for many households. However, moving overseas can bring with it concerns about whether an ISA can still be kept, whether contributions can continue, and how local tax rules may affect the value of those investments.
The right approach depends on several factors, including your future residency plans, tax position and financial objectives, all of which should be considered before deciding whether to retain an ISA or review alternative arrangements.
Expats intending to return to the UK may, for example, have a very different set of priorities from those relocating abroad permanently or as part of their long-term retirement plans.
Can British Expats Retain an ISA After Relocating Abroad?
There is no rule requiring an ISA account to be closed or transferred, so yes, British expats living overseas have every right to retain an ISA if it remains appropriate for their circumstances. However, non-UK residents typically cannot make any further contributions. Exceptions may apply to qualifying Crown employees working overseas and their spouses or civil partners.
Although the ISA retains its UK tax advantages, income and realised gains may be taxable under the rules of the account holder’s country of residence. Treatment varies considerably between jurisdictions.
One situation in which keeping an ISA may be suitable is when an expat intends to become a UK resident again in the future. At this point, they may resume making contributions and will typically be entitled to the UK tax treatment.
Exceptions apply, but usually only in very specific scenarios, such as for Crown employees stationed overseas.
Lifetime ISAs (LISAs) have separate subscription rules. The annual contribution limit is £4,000, which counts towards the overall £20,000 annual ISA allowance. The first payment into a LISA must normally be made before the account holder turns 40, and contributions can generally continue until age 50.
The usual restrictions on ISA contributions while living overseas also apply, subject to exceptions for qualifying Crown employees working abroad and their spouses or civil partners.
How Are ISAs Taxed for Expats Living Overseas?
Assuming that the tax advantages linked to ISAs in the UK will apply everywhere is incorrect.
Taxation depends on where you move. Other countries may tax interest, dividends and realised investment gains arising within an ISA. Whether tax applies, and when it becomes payable, will depend on the local classification of the account and its underlying investments.
There isn’t one correct approach because:
- Expats who are relocating temporarily or plan to return to the UK in the future might decide to retain an ISA and resume contributions upon their return.
- ISAs do not have to be closed or reinvested, and in some situations expats may choose to retain them as part of their long-term investment planning.
- British nationals who do not expect to return to the UK may decide that closing the account and moving the funds to another investment or savings product in their new country of residence is appropriate following a review of their wider financial position and savings and investment portfolio.
In every case, it is important to assess other factors before making decisions, from the timing and permanence of your move, where you expect to become a tax resident, how that country treats ISA returns, and how well your existing ISA fits into your long-term plans.
Whichever options appear most appropriate, an ISA can normally be transferred between providers while the holder is non-resident, although individual providers may restrict services or decline overseas-resident clients.
An ISA transfer should normally be completed through the formal provider-to-provider transfer process. Withdrawing the money personally before moving it may result in the funds losing their ISA status.
What Should Prospective Expats Consider Before Making ISA-Related Decisions?
There are both advantages and potential drawbacks to retaining an ISA, and choosing the most relevant solution will rely on an evaluation of your plans, portfolio and expectations. The key facts to consider are that:
- You can typically only make contributions or open a new ISA as a UK resident, but you are not obliged to close an account if you relocate.
- Tax obligations arising on the growth within an ISA will depend on your place of residence and the applicable tax legislation.
Where an ISA or its investments are denominated in sterling, but the holder’s spending is in another currency, exchange-rate movements may affect the value of withdrawals and the portfolio when measured in the spending currency.
Rather than deciding whether or not to retain an ISA based solely on its current value, expats should assess their ongoing financial plans, which may help clarify whether this product will continue to meet their long-term objectives.
Reinvesting an ISA as an Expatriate
Some expatriates may consider withdrawing funds from an ISA and investing them through another arrangement. However, withdrawing funds normally means giving up the UK ISA protection on that money, and the transaction may create tax, investment and product consequences.
Discussing your requirements with a wealth manager is recommended, because the most suitable action will depend on all other aspects of your savings and portfolio. The rules and requirements within your intended country of residence are also relevant, since some types of accounts and financial products may be categorised and taxed differently.
One aspect that might influence those decisions is the reform of ISAs in the UK, which is due to take effect from 6 April 2027.
Allowances for Cash ISA contributions will fall from £20,000 to £12,000 for those under 65, although the overall annual £20,000 limit for all ISA deposits will remain in effect. The remaining overall ISA allowance may be used for other eligible ISA subscriptions, subject to the separate rules and limits applying to each ISA type.
In addition, from 6 April 2027, account holders under 65 will generally be unable to transfer funds from stocks and shares or Innovative Finance ISAs into Cash ISAs. A 22% charge will apply to interest paid on cash held within stocks and shares ISAs and Innovative Finance ISAs. This is intended to prevent the lower Cash ISA limit from being circumvented.
Prospective expats considering a move overseas should consult their adviser about how these changes may affect future contribution, transfer and asset-allocation decisions.
Accessing Professional ISA Advice for Foreign Nationals
Moving to another country doesn’t necessarily mean expats are required to close an ISA, but they must understand how the tax treatment and value of an ISA may change when relocating.
