Leaving the UK is a significant financial decision as much as a personal one. Many people assume that moving abroad automatically ends their UK tax obligations. It does not. Your UK tax residence status after departure depends on a structured legal test — and getting it wrong can mean HMRC continues to tax your worldwide income long after you have left. Our tax advisors at Tax Accountant work with individuals, expats and internationally mobile professionals on UK tax residence, and the most common mistake we see is people assuming they have become non-resident without properly working through the test.
What Is the Statutory Residence Test?
The Statutory Residence Test — known as the SRT — is the legal framework HMRC uses to determine whether an individual is UK resident for tax purposes in any given tax year. It was introduced by Finance Act 2013 and applies from 6 April 2013 onwards. Before that date, residence was determined by HMRC guidance and case law. The SRT replaced that uncertainty with a structured, rule-based approach.
The SRT works in a specific sequence. You work through three stages in order. The first is the automatic overseas test. If you meet this, you are automatically non-resident and the analysis stops there. If you do not meet it, you move to the automatic UK residence test. If you meet that, you are automatically UK resident. If you meet neither automatic test, you apply the sufficient ties test, which considers both your UK connections and the number of days you spend in the UK. HMRC’s guidance on the Statutory Residence Test is the authoritative reference for anyone working through this analysis.
The Automatic Overseas Test: The Cleanest Route to Non-Residence
The automatic overseas test gives you non-resident status without needing to count ties. You meet it if any one of three conditions applies.
The first condition applies if you were UK resident in one or more of the three previous tax years and you spend fewer than 16 days in the UK in the current tax year. The second condition applies if you were not UK resident in any of the three previous tax years and you spend fewer than 46 days in the UK. The third condition applies if you work full-time overseas and spend fewer than 91 days in the UK, with no more than 30 of those days involving more than three hours of UK work.
For the full-time overseas work condition, full-time means averaging at least 35 hours of work per week overseas across the tax year. The averaging calculation has specific rules — gaps in work of more than 30 consecutive days disrupt the continuity of the period and need careful analysis. Days spent travelling to or from the UK that would otherwise count as UK days can be excluded in certain circumstances, as can days where you are in the UK due to an exceptional circumstance beyond your control.
If you meet any of these three conditions, you are non-resident for the tax year regardless of your ties to the UK.
The Automatic UK Residence Test: When You Are Automatically Resident
If you do not meet the automatic overseas test, the next step is to check whether you are automatically UK resident. You are automatically resident if any of the following apply.
You spend 183 days or more in the UK in the tax year. You have a home in the UK for at least 91 days, you are present in that home for at least 30 days during the year, and you either have no overseas home or your overseas home is one where you spend fewer than 30 days. You carry out full-time work in the UK across the tax year, meeting a similar 35-hours-per-week average test but measured against UK work rather than overseas work.
The 183-day rule is the most straightforward. Most people know about it. What catches people out is the home condition. You can become automatically UK resident through a home tie even if you spend well under 183 days in the UK — provided you have a UK home available to you and you use it.
The Sufficient Ties Test: When Neither Automatic Test Applies
Where neither automatic test determines your status, the sufficient ties test applies. This test combines your number of UK ties with your day count in the UK. The more ties you have, the fewer days you can spend in the UK before becoming resident.
There are five UK ties. The family tie applies where your spouse, civil partner or minor child is UK resident. The accommodation tie applies where you have a place to stay in the UK that is available to you for a continuous period of at least 91 days and you spend at least one night there. The work tie applies where you work in the UK for 40 or more days in the tax year, with a working day defined as one where you work for more than three hours. The 90-day tie applies where you spent more than 90 days in the UK in either of the two preceding tax years. The country tie applies where you spend more days in the UK than in any other single country during the tax year.
The day count thresholds for the sufficient ties test differ depending on whether you were UK resident in any of the three preceding tax years. For someone who was previously UK resident, the thresholds are as follows. With four or five ties, you become UK resident if you spend more than 45 days in the UK. With three ties, the threshold is 90 days. With two ties, it is 120 days. With one tie, it is 182 days.
For someone who was not UK resident in any of the three preceding years, fewer ties are counted and the thresholds are more generous. With four or more ties, the threshold is 120 days. With three ties, it is 182 days. With two or fewer ties, you remain non-resident regardless of days spent.
What Counts as a Day in the UK?
A day in the UK for SRT purposes is any day when you are present in the UK at midnight. Days of departure and arrival are generally not counted unless you spend the night. However, the transit exemption does not apply where you are in the UK for reasons other than passing through an airport. Days spent in the UK due to an exceptional circumstance — a medical emergency, national or local emergency, or war — can be disregarded up to a maximum of 60 days in a tax year.
Keeping an accurate record of every day you spend in the UK is essential. Our team advises all clients leaving the UK to maintain a contemporaneous travel diary. HMRC can and does request day-by-day records when investigating residence status, and reconstructing travel history years after the fact is difficult and unreliable.
Split Year Treatment
In the tax year you leave the UK, your status is normally determined for the full year. However, split year treatment can apply in specific circumstances, allowing the year to be divided into a UK resident part and a non-resident part. If split year treatment applies, you pay UK tax on worldwide income only for the resident part of the year, and UK source income only for the non-resident part.
There are eight cases under which split year treatment can apply. The most commonly relevant for people leaving the UK are Case 1 — where you start full-time overseas work — and Case 4 — where you cease to have a UK home. Each case has specific conditions that must be met. The conditions are precise and the cases are not interchangeable. Our foreign income tax service covers split year analysis as a standard part of the advice we give to clients in the year of departure.
The Temporary Non-Residence Rules
Leaving the UK does not always produce a clean break. The temporary non-residence rules apply where an individual becomes non-resident for a period of fewer than five complete tax years and then returns to the UK. Where those rules apply, certain income and gains that arose during the non-resident period are charged to UK tax in the year of return as if they had arisen in that year.
The types of income and gains caught by the temporary non-residence rules include certain pension withdrawals, distributions from close companies and capital gains on assets held before departure. The five-year period is measured from the last tax year of UK residence to the first tax year of return. If you plan to leave the UK but know you will return within a few years, the temporary non-residence rules mean you cannot simply realise gains or draw pension income tax-free during your absence. Planning around this requires careful timing and advice before departure.
UK Tax on Income and Gains After Leaving
Becoming non-resident does not eliminate all UK tax obligations. Non-residents continue to pay UK income tax on UK-source income. This includes employment income for UK duties, rental income from UK property, pension income depending on the applicable double tax treaty, and savings and investment income in some circumstances.
For capital gains, non-residents are not normally subject to UK CGT on the disposal of assets other than UK property. However, disposals of UK residential and commercial property by non-residents are within the scope of UK CGT and require a report to HMRC within 60 days of completion. Our personal capital gains tax service covers this for clients who dispose of UK property while living abroad.
Inheritance tax operates on a different basis entirely. IHT looks at domicile, not residence. A person who is UK domiciled remains within the scope of UK IHT on their worldwide assets regardless of where they live. Becoming non-resident does not change your domicile status. Domicile of origin is acquired at birth and changing it requires clear evidence of a settled intention to live permanently in another country — a standard that is not easy to meet and that HMRC scrutinises carefully. Our inheritance tax service addresses the IHT position for clients who have left or are planning to leave the UK.
Double Tax Treaties
The UK has double tax agreements with more than 130 countries. These treaties determine which country has the right to tax specific types of income and gains where both countries could otherwise make a claim. The treaty between the UK and your country of residence after departure may affect the tax treatment of your UK pension, employment income, rental income, dividends and capital gains.
Treaty provisions override domestic law where they give a more favourable outcome, but claiming treaty relief is not automatic — it requires an application in most cases. HMRC’s guidance on double taxation relief explains the process. The ICAEW has published useful technical commentary on cross-border tax and treaty issues for those dealing with more complex international positions.
Notifying HMRC When You Leave
You should notify HMRC when you leave the UK. The standard way to do this is by completing form P85, which tells HMRC the date you left, where you are going and what is happening with your UK income sources. Submitting P85 triggers a review of your tax code for any continuing UK income and helps ensure you are not over-taxed on UK source income during the non-resident period.
You should also review whether you need to register for self-assessment, or whether an existing self-assessment registration remains relevant. Where you have UK rental income, you may need to register under the Non-Resident Landlord scheme. Where you have a UK pension, the applicable tax treatment depends on the treaty and may require an NT code application to HMRC.
How Our Tax Advisors Can Help
Leaving the UK triggers a cascade of tax decisions — residence analysis, split year treatment, notification to HMRC, treaty claims, pension planning and the timing of asset disposals — all of which interact with each other. Getting one wrong can create a liability that was entirely avoidable with proper planning.
Our team works with individuals in the year of departure and in subsequent years to ensure their UK tax position is correctly handled. We work through the SRT analysis for your specific circumstances, advise on split year treatment, prepare P85 notifications and self-assessment returns, handle non-resident landlord registration, advise on treaty claims and manage any HMRC correspondence that arises. We do this through our personal tax services and foreign income tax service.
If you are planning to leave the UK or have already left and are unsure of your tax position, get in touch with our team. The earlier you take advice, the more options are available and the cleaner the position on departure.
