Moving abroad does not automatically mean closing NS&I savings. What you can keep, add, withdraw or receive depends on the product, residence and payment route.
NS&I abroad: each action has its own rule
NS&I eligibility depends on the action. Keeping an account, opening one, adding money and receiving payments can have different conditions.
| Product or action | Open after moving abroad | Keep after moving | Add money | Receive money or withdraw |
|---|
| Existing Cash ISA | No new account if non-resident | Usually yes | Usually no new subscriptions | Check NS&I payment instructions |
| New Cash ISA | Usually no | Not applicable | Not applicable | Not applicable |
| Existing Premium Bonds | Not relevant | Usually yes, subject to terms | Check residence rules before buying more | A working payment route is vital |
| Other NS&I savings | Product-specific | Product-specific | Product-specific | Product-specific |
Can you open or add money abroad?
A non-UK resident normally cannot open a new Cash ISA. They also cannot make new payments into an existing ISA.
Narrow exceptions apply to some Crown employees and may also apply to their spouses or civil partners.
Premium Bonds need a separate check. You may keep existing holdings, but new or extra purchases can have different residence rules.
What happens to an existing ISA?
An existing ISA can normally stay open after you become non-UK resident. However, you generally cannot add new money.
Its UK tax treatment may continue. Your new country may still tax interest or require reports.
“Tax-free in the UK” does not mean tax-free everywhere.
Can premium bond prizes stay invested?
Premium Bonds enter monthly ERNIE prize draws. They do not pay fixed interest.
Holdings can range from £25 to £50,000. You may be able to keep Bonds while abroad.
Reinvestment and prize payments depend on current product terms and on working account details.
Product rules are not interchangeable
Do not assume a Premium Bonds rule also applies to Direct Saver, Income Bonds, Direct Cash ISA or older products.
NS&I rules can differ by product and action. This includes opening, paying in, changing payment details, closing and withdrawing.
For example, Cash ISA rules normally stop new subscriptions after an overseas move, although an existing ISA may still remain invested.
Premium Bonds holders abroad may retain eligible Bonds. That does not always mean they can make a new purchase.
Check current terms for the exact product and action. Do not rely on a general rule for non-UK resident savings.
Passport, address, tax and bank are separate
Nationality, residence, tax residence, postal address and bank details answer different eligibility and payment questions.
Use this dependency map: nationality helps identify you; residence can decide product access; tax residence decides reporting and tax; a postal address receives messages; a UK bank account may be needed to receive an NS&I payment. None automatically replaces another.
Does a british passport make you eligible?
A British passport proves identity and nationality. It does not give automatic eligibility for an NS&I product.
British nationality does not replace a residence condition. NS&I may also ask for address proof, National Insurance details or anti-money-laundering information.
Which address and bank details count?
Your correspondence address is where NS&I sends messages. Residence is where you genuinely live.
Update records accurately after moving. A UK bank account may help with BACS payments.
However, it does not prove UK residence, and your bank can close it under its overseas-customer policy.
Tax residence decides where savings income and prizes may face tax or reporting. It can differ from nationality, domicile and bank location.
HMRC decides UK treatment. Australia, Ireland, EU countries and the United States apply their own rules.
Those rules can include CRS or FATCA reporting.
Protect NS&I payments before leaving the UK
Confirm a replacement payment route before departure. Do this before your UK bank account closes.
Update these details before departure
Update your postal address, email, mobile number and tax-residence information where needed. Keep your NS&I and Premium Bonds holder numbers safe.
Check that you can receive login codes abroad. Check that your nominated account can accept BACS payments.
Do this while your current UK account remains active.
If your UK bank closes your account
Ask NS&I before the closure date about a compatible replacement UK account. Ask whether it can pay that account for your product.
If no route exists, ask about paper payment options. A warrant or cheque may be slow and hard to cash abroad.
Cashing either may also involve collection, conversion or receiving-bank charges.
Use NS&I’s official overseas contact details. Check the current contact page before calling, as arrangements can change.
State the product and your country of residence. Explain whether you are keeping, adding, withdrawing or receiving money.
Request written confirmation if the answer affects eligibility or payments.
Check the payment account, not just the balance
Before relying on a UK account abroad, check that it remains open for residents in your new country. Check that it can receive the relevant BACS payment.
The account should be in your own name. Some products use a nominated account.
NS&I may require a compatible UK bank or building society account. It may not send money directly to every overseas account.
This can apply even if an international bank has a UK brand. Joint accounts, third-party accounts and mismatched details can delay payment.
Keep proof of your account details. Ask NS&I which payment route applies to your product.
If the account closes, update NS&I payment instructions promptly. Do not wait for interest, a withdrawal or a prize payment to fail.
Avoid these costly assumptions after a move
Official product terms, bank policies and local tax rules matter more than expatriate anecdotes.
Premium bond prizes may be taxable abroad
Premium Bond prizes are generally free of UK tax. They may be taxable or reportable where you live.
This risk can apply in Australia, Ireland, EU states or the United States. Cash ISA interest can bring the same surprise.
Overseas tax bodies may treat either as normal savings income.
Keep the official evidence
Save product terms, account messages and call dates. Rules can change, and social-media screenshots are not evidence.
Check product terms first. Test the bank payment route second, then review tax effects.
This guide is not the main guide for UK residents who travel temporarily. It is also not personal tax advice, estate planning or an individual investment recommendation. Check current NS&I conditions and seek professional advice where appropriate.
Tax depends on the product and the country
UK tax-free savings status does not settle the tax position where you live. Cash ISA interest is generally free from UK income tax.
A foreign tax body may treat it as taxable savings income. It may also require foreign tax reporting.
Premium Bond prizes are generally free of UK tax. Overseas treatment can still differ.
A country may tax the prize or classify it differently. It may require a declaration even when no tax is due.
Interest from taxable NS&I products may also belong on a local tax return.
Australia, Ireland, EU countries and the United States have separate rules. US taxpayers may face extra reporting requirements.
Keep annual statements and prize records. Then check UK tax residence rules and the rules in your country of residence.

What matters most:- Keeping an NS&I product does not always allow new purchases or ISA subscriptions.
- A British passport, UK address and UK bank account solve different problems.
- Test your BACS payment route before moving abroad or closing a bank account.
- Review overseas tax on ISA interest and Premium Bond prizes, even when UK tax is not due.
