Expert Interview: UK Tax for Expats — What You Need to Know in 2026

UK expats regularly underestimate the complexity of their UK tax obligations. Non-residency does not eliminate UK tax liability — it changes its shape. We spoke with a specialist in UK cross-border taxation about how the rules work in practice, the mistakes that generate HMRC enquiries, and how to manage UK pension and investment income tax-efficiently as a non-resident.

This interview is for general information only. Tax law is complex and individually determined. Always seek specialist advice.

QROP Direct: Let's start with the basics. When someone moves abroad, do they automatically stop paying UK tax?

No — and this misunderstanding causes real problems. Moving abroad changes your UK tax residency status, which changes what you are taxed on in the UK. But it does not eliminate UK tax liability entirely. Non-residents remain subject to UK tax on certain UK-source income: rental income from UK property, UK-source employment income, dividends from UK companies (with some exceptions under double taxation agreements), and pension income where the relevant DTA allocates taxing rights to the UK.

What non-residency does remove is liability on foreign income and gains — income earned abroad, overseas investment returns, foreign pension income. So the picture is: UK-source income remains taxable in the UK (subject to DTA provisions), while foreign income is no longer taxable in the UK once you are genuinely non-resident.

QROP Direct: How does the Statutory Residence Test work in practice? What do expats get wrong?

The SRT has three broad components: automatic overseas tests that make you definitely non-resident regardless of ties, automatic UK tests that make you definitely UK resident regardless of ties, and a sufficient ties test for those in the middle ground.

The most common mistake I see is people assuming that simply moving to another country makes them non-resident from the day they leave. That is not how it works. UK residency is determined for the whole tax year. If you leave the UK in October, you may still be UK resident for the whole of that tax year (April 6 to April 5), depending on how many days you spent in the UK and what ties you retain.

The second mistake is the day count. Many clients do not realise that HMRC counts any day you are in the UK at midnight as a UK day — travel days, layovers, holiday visits to family, business meetings. Clients who regularly visit the UK for work or family can accumulate UK days faster than they expect, and crossing the relevant threshold triggers residency under the sufficient ties test.

The third mistake is ignoring the split year rules. When you leave or arrive in the UK during a tax year, split year treatment may apply — meaning you are treated as UK resident for part of the year and non-resident for the other part. This is beneficial in many cases, but you have to claim it correctly on your tax return.

QROP Direct: What are the main UK tax issues for expats receiving UK pension income?

The first is double taxation. Most UK expats in major pension-paying destinations receive their pension initially with UK income tax deducted at source by the pension provider. They are then also obligated to declare that income in their country of residence. Without action, they pay tax twice on the same income.

The remedy is submitting Form DT Individual — the HMRC form for claiming relief under a double taxation agreement. This form, submitted to the relevant HMRC office with the DTA jurisdiction code, instructs HMRC and the pension provider to pay the pension gross (without UK deduction) where the DTA assigns taxing rights to the country of residence. Most private pensions are taxable in the country of residence under major DTAs — and once the form is processed, future payments come without UK tax deduction.

The common error is not doing this at the point of moving abroad — letting months or years pass with UK tax being deducted, and then trying to recover it retrospectively. HMRC refunds are possible but slow. Do the DT Individual before your first pension payment if possible.

QROP Direct: What about people with UK rental income?

UK rental income is always taxable in the UK for non-residents under domestic law, regardless of DTA provisions. Most DTAs specifically preserve the UK's right to tax income from UK real estate.

The key relief available is the Non-Resident Landlord Scheme. Under this scheme, letting agents and tenants should deduct UK basic rate tax from rental income and pay it to HMRC — unless the landlord applies to HMRC to receive rent gross (no withholding), which HMRC grants to non-residents with a history of tax compliance. The landlord then self-assesses and pays tax on net rental profit as part of a UK Self Assessment return.

Non-resident landlords must still calculate and pay UK income tax on rental profit — allowable deductions include mortgage interest (restricted), management fees, maintenance, insurance, and letting agent costs. Capital gains tax also applies to UK residential property for non-residents at standard CGT rates on gains realised since April 2015.

QROP Direct: Are there situations where HMRC challenges a non-resident claim?

Yes, and increasingly. HMRC has become more sophisticated in identifying cases where non-resident status appears inconsistent with observed behaviour. This includes cross-referencing entries and exits logged at border control, social media information, property ownership, children at UK schools, spouse remaining in UK, continued participation in UK professional activities, and patterns of pension and investment income tax returns.

The most common challenge categories are: people who claim non-residency but spend more time in the UK than their day count suggests because of the tie rules; people whose family arrangement means UK ties are retained; and people who left the UK but returned before five full tax years and failed to understand the implications for the intervening years.

My strong advice is to keep a contemporaneous record of days in and outside the UK — a simple diary or calendar with flight bookings attached — from the day you leave. If HMRC investigates years later, this is your primary documentary evidence of non-resident status.

QROP Direct: Are there common situations where expats pay more UK tax than necessary?

Frequently. The most significant over-payment is on pension income: failing to submit the DT Individual form and continuing to pay UK income tax on pension income that the DTA assigns to the country of residence. This can continue for years.

The second is on UK savings interest and dividends. Many non-residents continue to receive these without claiming available exemptions or completing the correct HMRC forms. The annual exempt amounts and DTA relief provisions can significantly reduce UK tax on investment income.

The third is Capital Gains Tax on UK residential property. CGT reporting for non-residents has been mandatory and time-limited (60 days from completion) since 2020. Clients who sell UK properties without reporting within the deadline face automatic penalties and interest — even if no CGT is ultimately due.

QROP Direct: Any final thoughts on what expats should do to manage their UK tax position well?

Three things. First, deal with your UK tax position proactively from the day you move abroad — not reactively years later when HMRC contacts you or you need to access your pension.

Second, use a UK tax adviser who specialises in non-resident and expat work. Generic UK tax advice assumes UK residency. The non-resident rules are different and the specialist knowledge makes a material difference.

Third, maintain records. Day counts, bank statements showing where income went, evidence of overseas tax payments — all of this becomes critical if your non-resident status is ever questioned. Good record-keeping from day one costs nothing and avoids enormous stress later.

QROP Direct: One more question — how should expats approach QROPS versus International SIPPs from a tax perspective?

The tax analysis is often misunderstood. People focus on the tax treatment of the pension vehicle in isolation, without integrating it with the country of residence tax framework.

A QROPS in Malta, for example, allows income to be drawn with favourable Maltese tax treatment — but only if you actually live in Malta. A UK national living in France holding a Malta QROPS pays French income tax on Malta QROPS income, not Maltese tax. The in-country tax rates apply regardless of where the pension is held.

The genuine tax advantages of QROPS typically relate to: the absence of a death benefit lump sum tax charge in some jurisdictions; greater flexibility on the timing and structure of drawdown; and in specific circumstances, more favourable DTA treatment. These are real advantages but require careful analysis for each specific jurisdiction combination.

For most expats in most EU countries, the post-October 2024 OTC extension means that the International SIPP, with its UK regulatory framework and absence of transfer charge, is the cleaner starting point for analysis. The question should be: what does a QROPS offer that a well-structured International SIPP does not, that justifies the 25% OTC? In many cases, the answer is: not enough.
