Clear advice when your place of residence affects your tax position

Your UK tax position depends on one critical question: Are you UK tax resident or not? The answer is rarely as simple as where you live, where your family is, or how often you fly in and out of the country. UK tax residency is governed by detailed legislation, and small changes in circumstances can have significant tax consequences.

At The British Boffins, we provide specialist UK residency advice to individuals, business owners and UK expats, helping you understand your position and plan with confidence. Whether you are leaving the UK, returning, or living internationally, we help you navigate the rules clearly and correctly.

What UK tax residency means

UK tax residency determines how your income and gains are taxed. If you are UK resident, you are generally taxable on your worldwide income and gains. If you are non-UK resident, UK tax is usually limited to UK-source income and gains, subject to specific rules.

Residency is not a matter of choice. It is determined by the Statutory Residence Test, a detailed framework that looks at your time spent in the UK, your connections to the UK, and your pattern of travel across tax years.

Understanding how the test applies to your personal circumstances is essential, particularly if you have income, assets or business interests across multiple countries.

Our UK residency advisory service

We provide clear, tailored advice on your UK residency status, based on a detailed review of your circumstances. This includes analysing your day count, ties to the UK, work patterns, and any changes in your personal or professional situation.

Where relevant, we advise on split year treatment, which can allow a tax year to be divided into resident and non-resident periods when you leave or return to the UK. We also consider how double tax treaties interact with UK domestic rules where you are resident in another country.

Our advice is practical and forward-looking. We do not just tell you where you stand today, but help you understand how future plans, travel patterns or lifestyle changes could affect your tax position.

Who this service is for

Our UK residency advisory service is commonly used by individuals leaving the UK, UK expats living overseas, internationally mobile professionals, business owners, and individuals returning to the UK after a period abroad.

It is particularly valuable where there is significant income, property ownership, shareholdings, or where residency status has changed or is expected to change.

Why professional residency advice matters

UK residency is an area where assumptions often lead to costly mistakes. Spending slightly more time in the UK than planned, maintaining certain ties, or misunderstanding the rules around workdays can unintentionally trigger UK tax residency.

Getting this wrong can result in unexpected tax liabilities, penalties, and lengthy discussions with HMRC. Proper advice reduces risk, provides certainty, and allows you to plan your affairs with confidence.
