Being a British Expat: The Complete Financial Planning Guide

The decision to move abroad is life-changing — but the financial implications are more complex than most British nationals anticipate. Some things genuinely change the day you leave. Others persist for years, and a few follow you indefinitely regardless of where you live. Understanding the distinction is the foundation of good expat financial planning.

What changes when you leave the UK

Tax residency — the Statutory Residence Test

UK income tax does not end automatically when you depart. HMRC uses the Statutory Residence Test (SRT) to determine your UK tax status each tax year. The SRT has three components: the automatic overseas tests (which can confirm non-residence quickly), the automatic UK tests (which can trap you as resident despite significant time abroad), and the sufficient ties test (which looks at family connections, accommodation, work, and time spent in the UK).

The most common mistake is spending too many days in the UK in the year of departure — the third automatic UK test applies to individuals with four or more UK ties who spend 46+ days in the UK. Careful day-counting matters. Plan your departure date to ensure you satisfy the automatic overseas tests in the tax year of leaving if possible.

The split-year rules allow the tax year to be split between UK residency and non-residency in certain circumstances. A UK tax return is required for the year of departure.

NHS access

NHS entitlement is based on ordinary residence in the UK, not on citizenship or National Insurance contributions. Once you are genuinely living abroad, you lose the right to free NHS care (other than for immediately necessary treatment when visiting the UK). This is not means-tested and applies to everyone. International Private Medical Insurance (IPMI) from providers such as Cigna, AXA, Bupa International, or Allianz should be in place before departure.

When visiting the UK, you are entitled to treatment for conditions that become acute during the visit, but not for pre-planned or ongoing treatment.

State benefits

Most UK means-tested benefits cease when you leave the UK. Child Benefit stops. Universal Credit requires UK residence. Disability benefits can be complex — some continue, some do not. Contributory benefits (including UK State Pension) operate differently from means-tested ones.

Electoral roll

British nationals living abroad can register as Overseas Electors and vote in UK general elections. The previous 15-year limit was abolished on 16 January 2024 (Elections Act 2022): any British citizen who was previously registered to vote in the UK, or who previously lived in the UK, can now register regardless of how long ago they left. The overseas registration also now lasts up to three years rather than one.

UK driving licence

A UK driving licence remains valid in the UK indefinitely. In most EU countries, you must exchange it for a local licence once you become resident (typically within 90 days to 12 months depending on country). Some countries outside the EU require re-testing rather than exchange. Check the rules for your specific destination.

What stays UK-connected

National Insurance number

Your NI number never changes and never expires. It remains your identifier for all UK tax, pension, and government interactions, regardless of where you live or how long you have been away.

State Pension accrual

UK State Pension requires 35 qualifying years of NI contributions for the full new State Pension (£241.30/week in 2026/27, around £12,548 a year). Years already accrued before departure are preserved. When abroad, you can continue building qualifying years through:

• Class 2 contributions (£3.45/week in 2025/26) — for those working abroad in certain circumstances
• Class 3 voluntary contributions (£17.45/week in 2025/26) — available to most UK nationals living abroad

The cost of topping up gaps — particularly for earlier years in the pre-2016 transitional period — is remarkably low relative to the lifetime pension value. Check your NI record on the Government Gateway website (accessible from abroad) and take advice on whether to fill gaps.

UK pension pots

Private pension pots (SIPPs, occupational pensions) stay in the UK. They do not need to be moved when you leave. Drawdown from a SIPP can be paid into a foreign bank account. The key action is obtaining the correct tax treatment — see the pension section below.

UK property and rental income

UK rental income remains taxable in the UK for non-residents. If you let a UK property while living abroad, you must register with HMRC under the Non-Resident Landlord Scheme (NRLS). Under NRLS, a UK letting agent must withhold 20% tax on rental payments before paying them to you, unless you have a valid NRLS approval notice (applied for via form NRL1). Apply for the NRLS certificate promptly — it takes several weeks to process.

UK property is within scope of UK Capital Gains Tax for non-residents on disposal. Since April 2019, non-residents must report and pay CGT on UK residential property gains within 60 days of completion.

Long-term-resident IHT exposure

From 6 April 2025 the UK replaced the old domicile-based IHT system with a residence-based one. UK IHT on your worldwide estate now depends on whether you are a "long-term UK resident" — broadly, UK tax resident for at least 10 of the previous 20 tax years — not on domicile or "deemed domicile", which no longer govern IHT. A long-term UK resident pays UK Inheritance Tax at 40% on worldwide assets above the nil-rate band (£325,000, frozen to April 2031, plus the residence nil-rate band of up to £175,000 in applicable cases).

Crucially, this exposure does not end the day you leave. Once you have been UK resident for 10 of the previous 20 years, worldwide IHT exposure continues for a tail of between three and ten years after departure, depending on how long you were resident. This is a significant change that affects many expats who left the UK recently, and it means long-standing British nationals abroad can no longer rely on having shed UK domicile to escape IHT.

Bank accounts

UK banks often close accounts when they become aware of non-residence. This may be forced by due diligence processes or requested by the bank as policy. Take steps to maintain at least one UK account for pension receipts, rental income, and UK financial transactions. Options include:

• HSBC and NatWest have relatively expat-friendly policies for long-standing customers
• Lloyds International and HSBC Expat are dedicated offshore/expat banking services based in the Channel Islands or Isle of Man, FSCS-equivalent protection
• Citi International Personal Bank for higher-net-worth requirements
• Starling Bank and Wise for day-to-day payments (though these are not full banking relationships)

The most important first steps when leaving

1. Inform HMRC — Submit form P85 (Leaving the UK) to confirm your departure and tax position. This triggers the end of PAYE obligations and the split-year assessment.
2. Notify your UK bank — Provide your new overseas address. Banks are legally required to know where you are tax resident. Concealing residence from a UK bank is a regulatory offence.
3. Apply for NRLS approval — If you are renting out UK property, submit form NRL1 immediately to stop the 20% withholding tax.
4. Obtain NT coding for UK pension income — If you are drawing a UK pension, apply to HMRC for a NT (nil tax) code under the relevant double tax treaty to stop UK withholding at source.
5. SRT analysis for departure year — Count your days in the UK carefully for the tax year of departure. Get specialist advice if the position is close to any SRT threshold.
6. IPMI coverage — Arrange international private medical insurance to cover the gap left by NHS non-entitlement.
7. Review UK investment structures — ISAs cannot receive new contributions from non-residents. UK-based investment accounts may have cross-border compliance restrictions. An internationally compliant portfolio bond or offshore investment account is the standard alternative for non-UK residents.
8. Review life insurance and protection — Many UK life insurance and income protection policies have geographic restrictions or exclude claims arising abroad. Review all policies at departure.
9. Update your will — A UK will may not address overseas assets adequately. A multi-jurisdiction estate plan is important if you own assets in more than one country.

Destination-specific planning

Different countries suit different financial profiles. The most popular UK expat destinations each have distinct tax, visa, and pension treaty positions:

• UAE — zero income tax, zero CGT, zero IHT (locally), excellent lifestyle for high earners. No double tax treaty with the UK for most purposes, so NT coding approach is used.
• Spain — Beckham Law flat 24% rate for first six years (for qualifying employment moves), then standard rates up to 47%. Large existing British expat community.
• France — moderate tax rates, very good healthcare, strong double tax treaty with the UK.
• Australia — large British expat community; Australia–UK double tax treaty governs pensions.
• USA — complex for UK nationals; US taxation on worldwide income applies to green card holders and citizens; careful planning required.
• Cyprus — non-dom regime, EU member, 0% tax on dividends and interest, low corporate tax. Our HQ location.
• Portugal — NHR closed; D7 visa available; good lifestyle and affordability.

Each destination has a dedicated financial planning guide on this site — see the Expat Financial Planning hub.

The returning British expat

Returning to the UK after years abroad involves a new set of financial considerations:

The split year on return — The SRT split-year rules may apply to the year of return, meaning UK tax residency resumes part-way through the tax year rather than on 6 April.

Resuming NI contributions — Class 2 or 3 voluntary contributions should be reviewed on return. If you have gaps from the period abroad, there may still be an opportunity to fill them.

Rebuilding UK financial infrastructure — Opening a UK bank account after years abroad can be surprisingly difficult without a UK address and UK credit history. Start the process before returning where possible.

ISA resumption — Once UK resident again, you can resume ISA contributions (subject to the annual ISA allowance). Existing ISA holdings are not affected.

Pension position on return — UK pension arrangements that were reconfigured for non-residence (NT coding, etc.) need to be reviewed on becoming UK resident again.

UK IHT re-exposure — Under the residence-based IHT system in force since 6 April 2025, returning to the UK rebuilds your years of UK residence and, once you reach 10 of the previous 20 tax years as a UK resident, brings your worldwide estate back within UK IHT at 40%. Domicile is no longer the test.
