What Makes You a UK Tax Resident?

Please be advised that the information in this article regarding QNUPS and IHT is no longer accurate due to the recent changes announced in the UK Budget.

We encourage you to stay informed and consult with a Soteria Trusts expert to navigate these changes effectively.

Navigating the complexities of tax residency in the UK can be challenging, but understanding the fundamentals is essential for ensuring compliance and optimizing your tax position. At Soteria Trusts, we aim to provide clear and comprehensive guidance on such crucial topics.

This article breaks down the key factors determining UK tax residency, helping you understand your obligations and benefits. 

The Statutory Residence Test (SRT) 

The primary tool used to determine tax residency in the UK is the Statutory Residence Test (SRT). Introduced in 2013, the SRT offers a structured approach to assess an individual’s residency status based on various criteria: 

• Automatic Overseas Tests: You are automatically considered non-resident if you: 

• Spend fewer than 16 days in the UK during the tax year. 

• Spend fewer than 46 days in the UK if you haven’t been a UK resident in the previous three tax years. 

• Work full-time overseas (averaging at least 35 hours a week) and spend fewer than 91 days in the UK, with no more than 30 days spent working in the UK. 

• Automatic UK Tests: You are automatically considered a UK resident if you: 

• Spend 183 days or more in the UK during the tax year. 

• Have a home in the UK for more than 90 days and you spend at least 30 days there during the tax year. 

• Work full-time in the UK for any period of 365 days, with more than 75% of those days being working days. 

• Sufficient Ties Test: If you don’t meet any of the automatic tests, your residency status is determined by the number of connections or ‘ties’ you have to the UK, combined with the number of days spent in the UK. These ties include: 

• A family tie (close family in the UK). 

• An accommodation tie (a place to live available for a continuous period of at least 91 days). 

• A work tie (40 or more days of work in the UK). 

• A 90-day tie (spending 90 or more days in the UK in either of the previous two tax years). 

• A country tie (spending more time in the UK than in any other country). 

Residence Implications for Taxation 

Understanding your residency status is crucial because it affects your tax obligations. UK tax residents are subject to UK tax on their worldwide income, while non-residents are only taxed on their UK-sourced income. Here are the implications: 

• Worldwide Income: If you are a UK tax resident, you must declare all your income, regardless of where it was earned. This includes salaries, rental income, interest, dividends, and capital gains. 

• Non-Residents: Non-residents are taxed only on their income sourced within the UK. This includes income from employment in the UK, rental income from UK properties, and certain pensions. 

Double Taxation Agreements (DTAs) 

Double Taxation Agreements (DTAs) play a vital role for expatriates and individuals with international assets. The UK has DTAs with many countries to prevent double taxation on the same income. Key aspects of DTAs include: 

• Relief from Double Taxation: These agreements typically allow you to claim tax relief or exemption in one country if you’ve already paid tax on that income in another country. 

• Tax Credits: DTAs often provide for tax credits where tax has been paid abroad, which can be offset against your UK tax liability. 

• Tie-Breaker Rules: In cases where an individual might be considered a resident in two countries, DTAs contain ‘tie-breaker’ rules to establish the country of residence for tax purposes.

Planning and Compliance 

Navigating UK tax residency can be complex, but careful planning and professional advice can help optimize your tax situation. Here are some strategies: 

• Maintain Detailed Records: To substantiate your residency status, keep comprehensive records of your travel, work, and accommodation. 

• Seek Professional Advice: Consulting with tax professionals, like those at Soteria Trusts, can help you understand your residency status and develop a tax-efficient strategy. 

• Regular Reviews: Regularly review your residency status, especially if your personal or professional circumstances change.
