Living abroad, earning overseas, or owning assets in more than one country might feel like freedom — until tax season arrives. Suddenly you’re dealing with conflicting rules, shifting thresholds, and the fear of being taxed twice on the same income.
UK rules alone are tough enough. Add another country, and the risks of missed filings, unexpected liabilities, or costly penalties go up fast. If you’re working internationally, managing a global business, or living as a British expat, the idea of staying compliant without overpaying can feel like a constant balancing act.
However, with careful planning there is always the opportunity of minimising your overall tax bill.
At Clark Jamison, we help individuals and entrepreneurs cut through the confusion. Our team specialises in international tax matters, from double taxation relief to residency planning, expat tax returns, and cross-border structuring for businesses. Whether you’ve lived overseas for a decade, are planning your first move, or thinking of returning to the UK, we offer precise advice designed to protect your income.
International tax advice
When your finances cross borders, so do your tax obligations but that doesn’t mean you should pay twice or risk falling foul of rules you didn’t know existed. We advise UK-based individuals and business owners with interests overseas on how to structure income, investments and operations efficiently.
Whether you’re trading internationally, setting up a foreign branch, managing employee secondments abroad or receiving income from multiple jurisdictions, we provide precise advice on minimising exposure, meeting compliance in each country, and making the most of available reliefs and treaties.
Expat tax advice
Moving abroad doesn’t mean leaving the UK tax system behind. Whether you’ve settled permanently, are working overseas temporarily, or plan to return in future, your tax position needs to be managed carefully.
From filing UK tax returns as a non-resident, to understanding how overseas income and assets are treated, we help expats stay compliant and avoid unnecessary tax. We also advise on the residency rules, remittance basis, and planning around key changes. Our goal is to keep things clear, legal and as efficient as possible, wherever you are in the world.
Digital nomad tax advice
Navigating taxation as a digital nomad can be complex—but with the right residency structure, remote professionals can often reduce their tax liability significantly. At Clark Jamison Ltd, we understand the intricacies of cross-border taxation, including how to optimize your residency status, and take advantage of low-tax jurisdictions.
Our team provides tailored advice for digital nomads, helping you legally minimize taxes while protecting your global income. Whether you’re freelancing from Bali, managing a business from Lisbon, or consulting remotely from multiple countries, we’ll assess your unique circumstances and design a compliant tax strategy that supports your lifestyle.
Who we help
We work with individuals, businesses and families navigating the complications of living, earning, or operating across borders. If your tax situation crosses jurisdictions, chances are we’ve seen it before.
- Individuals living or working abroad who want to stay compliant with HMRC while avoiding double taxation on UK pensions, rental income, or worldwide earnings.
- Non-domiciles or ‘Non-doms’ who despite the remittance basis being replaced by the new Foreign Income and Gains (FIG) regime from 6 April 2025 can still optimise via planning for, and taking advantage of, the new legislation’s exemptions and reliefs.
- Clients with dual tax residencies or split-year positions who spend time in multiple countries and need clarity on which tax rules apply and when.
- Remote workers overseas for UK employers or international clients, unsure how to report income correctly and avoid triggering tax in the wrong place.
- Oil and gas workers who are often drawn into complex cross-border rules, and whose rotational schedules often mean varying tax residency statuses from year-to-year.
- Foreign entertainers or sportspeople where earnings are received across multiple jurisdictions, meaning withholding rules and double tax implications abound.
- Entrepreneurs and directors with overseas business interests, from UK companies expanding abroad to owners managing operations in more than one jurisdiction.
- Non-residents with ongoing UK income, including landlords, investors, or returning expats facing tax on remitted foreign gains or unexpected HMRC demands.
- Families and Trustees with international assets, looking to plan ahead and avoid future liabilities tied to residency, or inheritance. We are also experts in inheritance tax, if you are looking to preserve your assets for the long term.
How we can help
Tax planning and compliance for expats
We can build strategies that minimise tax exposure and ensure you meet all obligations in the UK and overseas.
UK self-assessment for non-residents
Whether you’re renting out property or receiving UK-based income while living abroad, we prepare and file your returns with accuracy. Another job off your list.
Double taxation relief and treaty claims
We identify where treaties apply and ensure you avoid paying tax twice on the same income, helping to also recover overpayments.
Residency assessments
If you live or work across borders, your UK tax position depends on whether you’re classed as resident or non-resident and where the source of your income is. We help you understand how the rules apply to your situation and what steps to take to minimise tax and avoid unexpected liabilities.
Cross-border business structuring
For business owners with international operations, we advise on group structure, UK tax exposure of foreign operations, profit repatriation, and payroll.
Non-resident landlord tax returns
We handle UK tax filings for landlords based abroad, ensuring rental income is correctly reported and all allowances are used.
Repatriation and departure planning
The correct timing when leaving and returning to the UK can be highly beneficial, especially in relation to a business sale and related capital gains. We guide you through split year treatment, the temporary non-residence rules, and other risks tied to moving country.
HMRC enquiries and disputes
If HMRC comes calling, we can represent you. We respond to queries, handle investigations, and work to resolve any issues before they escalate.
How it works
We begin with a detailed conversation to understand your tax position, residency, and future plans. From there, we create a clear strategy tailored to your situation, handle all filings and communications with HMRC, and stay available for ongoing advice as circumstances change. Whether you’re planning a move or responding to one, we’ll help you stay compliant and in control.
