Everything you need to know about financial planning for uk expats in the UK.
Moving abroad as a UK citizen creates a unique set of financial planning challenges. You must navigate the tax and regulatory systems of at least two countries, manage investments and pensions across borders, protect your UK property and assets, and plan for a future that may involve returning to the UK. Without careful planning, expats can end up paying more tax than necessary, losing access to UK financial products, or leaving gaps in their pension provision.
Whether you are relocating for work, retiring overseas or running a business abroad, getting specialist financial advice early in the process is essential. The rules are complex and the consequences of getting things wrong can be costly.
Your tax obligations depend on your tax residency status, which is determined by the Statutory Residence Test (SRT). If you are non-UK resident, you are generally only taxed in the UK on UK-source income (such as rental income from a UK property, UK employment income and certain pension income). If you remain UK resident, you are taxed on your worldwide income.
It is possible to be tax resident in two countries simultaneously, in which case double taxation agreements (DTAs) between the UK and your country of residence determine which country has the primary right to tax different types of income. The UK has DTAs with over 130 countries, but the specific provisions vary. Understanding how the relevant DTA applies to your circumstances is critical.
💡 Even if you are non-UK resident, you may still be liable for UK tax on rental income from UK property, gains on UK property disposals, and income from UK employment. You may also need to file a UK Self Assessment tax return. Do not assume that leaving the UK eliminates all UK tax obligations.
Your UK State Pension is based on your National Insurance (NI) record. You need 35 qualifying years for the full new State Pension (currently £221.20 per week for 2025/26). If you have gaps in your NI record, you may be able to make voluntary NI contributions from overseas to fill them—this is often excellent value.
For workplace and personal pensions, leaving the UK raises several questions. Can you continue contributing? Should you transfer to an overseas pension scheme (a Qualifying Recognised Overseas Pension Scheme, or QROPS)? How will pension income be taxed when you draw it?
QROPS transfers can offer tax advantages in some jurisdictions, but they are complex and may trigger a 25% overseas transfer charge unless both you and the QROPS are in the same country or within the EEA. The decision should never be taken without specialist advice, as unsuitable transfers have been a major area of consumer detriment.
As a non-UK resident, you cannot open new ISAs or contribute to existing ones. However, you can keep your existing ISAs open and invested, and they continue to grow tax-free within the UK. This means it is worth maximising ISA contributions before you leave.
Many UK investment platforms restrict services to non-UK residents due to regulatory requirements. You may need to find a platform or adviser that specialises in serving expats. Investments held outside tax wrappers will be subject to the tax rules of your country of residence, which may differ significantly from the UK regime.
If you retain a UK property and let it out while you are abroad, the rental income is subject to UK income tax regardless of your residency status. Under the Non-Resident Landlord Scheme (NRLS), your letting agent or tenant is required to deduct basic-rate tax (20%) from the rent and pay it to HMRC, unless you apply for HMRC approval to receive the rent gross and pay tax through Self Assessment.
If you sell a UK property while non-resident, you may be liable for UK capital gains tax on any gain arising from April 2015 onwards. The annual CGT exemption is not available to non-residents unless you are absent for fewer than five complete tax years.
⚠️ The “temporary non-residence” rules mean that if you leave the UK for fewer than five complete tax years, gains realised while non-resident may be taxed on your return. This is designed to prevent people from briefly leaving the UK to sell assets and avoid CGT.
Leaving the UK affects your entitlement to NHS treatment. If you are living and working in an EU/EEA country, you may be covered by the local healthcare system under reciprocal arrangements. In other countries, you will need international private medical insurance (IPMI) to ensure access to healthcare.
IPMI policies designed for expats typically provide comprehensive global cover, including in-patient, out-patient, dental and maternity care. Premiums vary widely depending on your age, the country of residence and the level of cover. If you plan to return to the UK regularly, check whether the policy includes UK cover or whether you would rely on NHS entitlement during visits.
Expats need to consider how their estate will be distributed under the laws of multiple jurisdictions. Your UK will may not be recognised or effective in your country of residence, and vice versa. You may need wills in both countries, carefully coordinated to avoid conflicts.
Inheritance tax can also be complex. The UK charges IHT based on domicile rather than residence. If you are UK-domiciled (or deemed domiciled after being UK resident for 15 of the past 20 years), your worldwide assets are subject to UK IHT regardless of where you live. This is a common trap for long-term expats who assume that living abroad removes them from the UK IHT net.
