UK Statutory Residence Test: A Complete Guide for 2026/27
Whether you are UK tax resident is not decided by nationality, a visa, or how you feel about it — it is decided by a structured legal test. This guide walks through the automatic tests, the sufficient ties test, day-counting, and split-year treatment for anyone moving to, from, or between the UK and another country.
The Statutory Residence Test is applied as a sequence, not a single checklist. You work through it in a strict order: first the automatic overseas tests, then (if none apply) the automatic UK tests, and finally (if neither set of automatic tests gives a clear answer) the sufficient ties test. Whichever stage gives a definitive result settles your residence status for that tax year — you do not need to complete every stage if an earlier one already answers the question.
Automatic Overseas Tests
These tests can make you automatically non-UK resident without needing to look at ties at all. Broadly, they cover spending very few days in the UK in the tax year (the exact threshold depends on whether you were UK resident in any of the previous three tax years), working full-time overseas while keeping UK visits and UK workdays low, and a specific test for someone who dies during the tax year. Because the precise day thresholds vary by circumstance, check HMRC's RDR3 guidance for the number that applies to you rather than assuming a single figure applies to everyone.
Automatic UK Tests
If none of the automatic overseas tests apply, the automatic UK tests are checked next. These broadly cover spending a large number of days in the UK during the tax year, having a UK home that you use sufficiently while having no overseas home (or one you use much less), and working full-time in the UK. Meeting any one automatic UK test makes you UK resident for the year, again without needing to consider your ties.
Sufficient Ties Test
If neither set of automatic tests resolves your status, the sufficient ties test applies. It counts specific connecting factors — a UK-resident family tie, accessible UK accommodation, substantive UK work, spending 90 or more days in the UK in either of the previous two tax years, and (only relevant if you were UK resident in one of the previous three years) a "country tie" based on spending more days in the UK than any other single country. How many of these ties are needed to make you UK resident then depends on your day count for the year and whether you are an "arriver" (not UK resident in any of the previous three years) or a "leaver" (UK resident in at least one of them) — leavers need fewer ties to become resident at the same day count.
Day-Counting
For SRT purposes, a day generally counts as a UK day if you are in the UK at midnight at the end of that day. There are specific anti-avoidance rules aimed at frequent business travellers and transit passengers who might otherwise structure trips to avoid counting days, so travellers with an unusual travel pattern should check the detailed rules rather than assuming a simple midnight test always applies without exception.
Split-Year Treatment
In the tax year you arrive in or leave the UK, split-year treatment can divide the year into a UK part and an overseas part for Income Tax and Capital Gains Tax purposes, rather than treating the whole year under a single residence status. It only applies where you meet one of eight specific statutory cases (for example, starting full-time work overseas, or coming to the UK to take up full-time work) — moving mid-year on its own does not automatically qualify you, so the specific case conditions need to be checked carefully.
The Statutory Residence Test (SRT) is the legal framework HMRC uses to decide whether an individual is UK tax resident for a given tax year. It replaced the old, less certain case-law approach with a structured set of tests applied in order: the automatic overseas tests, the automatic UK tests, and, if neither gives a clear answer, the sufficient ties test.
What are the automatic overseas tests?
These are tests that, if any one of them is met, make you automatically non-UK resident for the year regardless of ties, without needing to go any further. Broadly they cover spending very few days in the UK in the tax year (with the exact day threshold depending on your residence status in the previous three years), working full-time overseas with limited UK workdays and limited UK visits, or (for someone who died during the year) equivalent tests. The precise day thresholds are set out in HMRC's RDR3 guidance and should be checked directly for your situation.
What are the automatic UK tests?
If none of the automatic overseas tests apply, the automatic UK tests are checked next. Broadly they cover spending a large number of days in the UK in the tax year, having a home in the UK that you use sufficiently and no home overseas (or an overseas home you use much less), or working full-time in the UK. Meeting any one of these automatically makes you UK resident for the year without needing to consider ties.

What is the sufficient ties test?
If neither set of automatic tests gives a clear result, the sufficient ties test is used. It looks at UK ties — family in the UK, accessible accommodation, substantive UK work, spending 90+ days in the UK in either of the previous two tax years, and (for people who were UK resident in any of the previous three years) being present in the UK more than elsewhere. The number of ties needed to make you UK resident then depends on how many days you spend in the UK that year, and whether you were resident in any of the previous three tax years (a lower day count triggers residence for 'arrivers' with fewer ties).
How exactly is a day counted?
Under the SRT, you are generally treated as spending a day in the UK if you are in the UK at midnight at the end of that day, subject to some specific anti-avoidance rules for frequent commuters and transit passengers. This differs from some other countries' residency day-counting methods, so travellers used to a different system should not assume the same counting approach applies in the UK.
What is split-year treatment?
Split-year treatment allows a tax year in which you either arrive in or leave the UK to be split into a UK part and an overseas part for certain tax purposes, rather than treating the whole year as either fully UK resident or fully non-resident. It only applies if you meet one of eight specific cases set out in the legislation (for example starting full-time work overseas, or coming to the UK to work full-time), and does not apply automatically just because you moved partway through the year.
Does the SRT apply to Income Tax, Capital Gains Tax, and Inheritance Tax equally?
The SRT itself determines residence primarily for Income Tax and Capital Gains Tax purposes. Following the 2025 non-dom reform, Inheritance Tax now uses a separate, residence-based 'long-term resident' test built on a different (multi-year look-back) structure, rather than the same year-by-year SRT mechanics, so residence for IHT purposes needs to be checked separately from residence under the SRT.
Can I work out my residence status myself?
HMRC provides a residence status checker tool and detailed guidance (RDR3) to help you self-assess, and many straightforward cases (clearly well under or well over the relevant day thresholds) can be worked out with care. However, cases near the boundary — particularly involving split-year treatment, working patterns, or multiple homes — are genuinely complex and errors can have significant tax consequences, so professional advice is worthwhile if your position is not clear-cut.
What happens if I get my residence status wrong?
Getting residence status wrong can mean under-declaring UK tax on income or gains that should have been reported, potentially leading to penalties and interest once HMRC identifies the error, or conversely overpaying UK tax you were not actually liable for. Because residence affects the tax treatment of a whole tax year, mistakes can be costly to unwind, which is part of why the SRT was designed to be a structured, checkable test rather than a subjective judgement call.
Does the SRT differ for Scotland, Wales or Northern Ireland?
No — the Statutory Residence Test itself is a single UK-wide test; there is no separate Scottish, Welsh or Northern Irish version of residence status. Once you are determined to be UK resident, Scottish Income Tax rates and bands, or Welsh Rates of Income Tax, then apply based on where in the UK you have your main home during the year, which is a separate question from the SRT residence test itself.
Disclaimer: Residence status determinations near the boundary of the tests are genuinely complex and fact-specific. This guide is general information, not personalised tax advice — get advice from a qualified tax adviser for your own situation.
