Expat Tax Accountant in the UK
Expat Accountants
Published: 11/12/2025
Living or working outside the UK doesn’t mean you can ignore HMRC — and that’s where a professional Expat Tax Accountant can help. Whether you’re a British expat or a non-UK resident with UK-source income, Accusolve’s International Services keep you compliant and tax-efficient across borders.
Expats and non-residents often juggle UK property income, investments, pensions and overseas earnings. The rules are nuanced — from the Statutory Residence Test to treaty relief under Double Taxation agreements and filing the correct Self-Assessment tax return. An experienced UK Expat Tax Accountant ensures you pay the right tax in the right place — and avoid penalties.
What Does an Expat Tax Accountant Do?
A UK expat accountant specialises in cross-border personal tax. We determine your position under the SRT, map UK and overseas income streams, and align filings with HMRC rules. Where you run a UK company or hold assets here, we coordinate with our Tax Services, Accounting Services, and Company Compliance Services teams for a joined-up plan.
- Accurate assessment of UK tax residency & domicile.
- Applying treaty relief under relevant double taxation agreements.
- Preparing and filing Non-Resident Tax Returns with HMRC.
- Optimising UK property, Capital Gains Tax and Inheritance Tax outcomes.
- Coordinating business-owner needs: UK Company Formation, Annual Accounts & Filing, VAT Registration and VAT Returns.
Why Expats & Non-Residents Need Professional UK Tax Support
Even if you live abroad, UK-source income can remain taxable — e.g. rent from a UK property (Non-Resident Landlord Tax), UK dividends, or gains on UK assets (CGT). Getting residency, split-year treatment and treaty claims right can save thousands. If HMRC has written to you, our HMRC Interactions & Risk Management for Expats service can resolve issues quickly.
Where work or payroll is involved, we advise on Employment, Payroll & Social Security Abroad and UK Payroll/PAYE obligations. Landlords and overseas founders benefit from digital bookkeeping and Accounting Software setup, delivered via our Virtual Finance Office.

FAQs: UK Expat Tax Accountants
You may still need to file if you have UK-source income (e.g. rent, dividends, gains). We’ll confirm your obligations and handle your Non-Resident Tax Return under the correct residency status and claim any double-taxation reliefs.
Non-resident landlords may need to register under the NRL scheme, file Self-Assessment, and keep digital records via our Accounting Software solutions. We’ll also assess treaty relief and future CGT on disposal.
