What is tax planning for expats?
Tax planning for expats is the UK-specific strategy and compliance work that aligns your residency status, reporting, and relief claims so your global income and gains are taxed once and filed on time. It includes Self Assessment, treaty relief, NIC decisions and planning around property, shares and pensions.
At Pearl Lemon Accountants, we combine residency analysis with document prep and on-time filing so expats avoid double taxation and penalties. Start with a quick checklist to see what you must gather, then confirm how the Statutory Residence Test applies in your situation. If you are still choosing an adviser, our roundup of the top international tax consultants in the UK explains what good cross-border advice looks like.
UK residency at a glance: SRT and split-year treatment
The Statutory Residence Test determines if you are UK tax resident. It looks at days in the UK, ties such as a UK home or work, and automatic tests. If you move mid-year, split-year treatment can divide the tax year into UK and overseas parts so you only report UK-relevant periods.
We assess your facts against the SRT, then document the conclusion for HMRC. That includes day counts, available ties, UK work patterns, and home availability. Where a move happens mid-year, we test split-year cases and note which case applies, for example starting full-time work in the UK or ceasing residence. Getting residency right drives every later step, from which income is reportable to how double taxation relief applies.

Our expat tax process and timeline
You get a simple, staged process: confirm residency, collect documents, prepare the return, review reliefs, submit to HMRC, then monitor for assessments and refunds. Most expats complete onboarding in days, not weeks, when documents are ready.
Here is how we work:
- Discovery call to scope residency, income sources and deadlines.
- Secure document collection and checklist sign-off.
- Draft preparation, including treaty relief and foreign tax credit analysis.
- Partner review and your approval.
- Electronic submission via HMRC services and payment advice.
- Post-filing support, including enquiries and amendments if needed.
We keep turnaround expectations clear at each step and align to HMRC key dates. If you are close to a deadline, we prioritise compliance first, then refine planning once the return is safely lodged. Ready to start? Book a Call. Prefer email? Contact us and we will reply promptly.

Tax filing and compliance for expats
We prepare and file your UK Self Assessment with the correct residency position, foreign income entries and reliefs applied. That includes UK salary, bonuses, property income, dividends, bank interest, and any overseas income that must be reported. We also register you with HMRC if you do not yet have a UTR.
Before submission we run a compliance checklist that covers identity details, income reconciliations, foreign tax credit claims, and payment on account triggers. After submission we track HMRC acknowledgements and statements so nothing is missed.
If HMRC opens an enquiry, see how specialists handle it in our guide to the top tax investigation specialists in the UK. Prefer to get moving right away? Contact us and we will start your registration or return preparation today.
Double Taxation Relief (DTAs and credits)
Double taxation relief prevents the same income being taxed twice. We map your income to the relevant UK treaty article, then apply either exemption or foreign tax credit so your final UK bill reflects relief correctly. This applies to employment, dividends, interest, royalties and some pensions.
Our team documents residency, source of income and taxes already paid abroad, then completes the right entries on your UK return. For common corridors like UK–US and UK–EU, we prepare treaty position notes that explain the claim if HMRC asks.
If you run a cross-border business, our Tax Advisory for Entrepreneurs service aligns treaty positions with how you pay yourself.
Capital Gains Tax (CGT) planning for expats
CGT planning for expats focuses on timing, reliefs and correct reporting. We calculate gains on UK property and shares, factor in annual exemptions, and test eligibility for Private Residence Relief. If you become or cease UK residence mid-year, we check how that changes which disposals fall within UK scope.
For UK residential property, 60-day reporting can apply alongside the Self Assessment return. We prepare both so deadlines are met and penalties avoided. For share sales, we reconcile broker statements to compute pool adjustments and allowable costs.
For practical scenarios, see our roundup of the top capital gains tax advisors in the UK. Directors selling shares as part of a broader plan may also need Tax Planning for Limited Companies to coordinate dividends, salary and gain timing.
National Insurance Contributions for expats
National Insurance for expats is about paying the right class, at the right time, so benefits like State Pension accrue without overpaying. We assess if Class 1 applies through UK employment, or if voluntary Class 2 or Class 3 fills contribution gaps when you work or live abroad.
We map your work status, residence and treaty position, then confirm which NIC class applies. For UK payroll, we check PAYE deductions match the correct category. For gaps, we weigh Class 2 or Class 3 contributions against expected benefits, then prepare the application. We also coordinate NIC with social security totalisation under treaties so you do not pay twice.

Inheritance Tax and non-dom planning
Inheritance Tax for expats hinges on domicile, asset location and available exemptions. Non-UK domiciled individuals are usually charged IHT on UK-situated assets, while UK domiciled or deemed-domiciled individuals face worldwide IHT. We structure ownership and gifting so exposure is managed and reliefs are used correctly.
We review your domicile status and any deemed-dom timelines, then map assets by location. Planning options can include UK life insurance written in trust, spousal exemptions, business relief, charity gifts, and in some cases de-enveloping or restructuring UK property. We also coordinate wills and executors across jurisdictions with your legal advisers.
See our detailed service pages for deeper planning support: Estate and Inheritance UK and integrated Family Office solutions for complex cross-border estates.
Tax-effective investments and pensions
Tax-efficient investing for expats focuses on UK wrappers and treaty-aware planning. We use ISAs for UK residents, pension contributions for potential relief, and asset placement that aligns with your residency and expected moves. We also review overseas plans to avoid mismatches in the UK tax system.
Our team assesses eligibility for UK personal pensions, confirms relief at source or net pay treatment, and models contribution levels against annual limits. For investments, we consider dividend and CGT allowances, fund reporting status, and offshore fund implications. We coordinate strategy with likely changes in your residence so the plan works before and after a move.

Expat tax refunds: eligibility and timing
Expat tax refunds arise when PAYE or payments on account exceed your final liability, or when treaty credits are applied after filing. We review your prior returns, correct coding notices, and claim repayments through HMRC so funds are released without delay.
Our review checks residency, income reconciliations and foreign tax credits. We amend errors, claim reliefs that were missed, and track HMRC processing through to repayment. For movers, split-year treatment and partial-year income often trigger refunds once the return is corrected.
See how we handle returns and recover overpayments on our tax return service page. If timing matters, Book a Call and we will confirm likely refund windows based on HMRC workloads.

Comparison: remittance basis vs arising basis
The remittance basis is a UK tax option for some non-doms where foreign income and gains are taxed in the UK only if brought to the UK. The arising basis taxes worldwide income and gains as they arise. Choosing correctly requires SRT, domicile and cost-benefit analysis.
| Feature | Remittance basis | Arising basis |
|---|---|---|
| Who can use it | Some non-dom UK residents | Any UK resident |
| What is taxed in the UK | Foreign income/gains only if remitted | Worldwide income/gains annually |
| Personal allowances | Often lost when claimed | Usually available |
| Charge to use | Possible remittance basis charge in later years | No charge |
| Record-keeping | Track clean capital and remittances | Standard annual records |
Residency drives your options, so we confirm the SRT position first, then model both bases against your income mix.
