UK Statutory Residence Test: What Travelers Need to Know
A practical explainer of what the UK's tax-residence test is trying to determine, why it is not just a simple 183-day rule, and where prior residence, ties, and HMRC guidance matter.
Last verified: August 2026
In short: the Statutory Residence Test (SRT) decides whether you are UK resident for a given UK tax year, and it is not a single 183-day threshold. You can be resident well below 183 days through a UK home, full-time UK work, or enough UK ties, and you can be clearly non-resident on very few days. It is a tax-residence framework, not visitor permission.
- Automatic day test
- 183 days or more (one route in)
- Counting window
- UK tax year, 6 April – 5 April
- A day counts if
- You are in the UK at midnight (deeming rules exist)
- Other routes in
- UK home, full-time UK work, sufficient ties
- Legal basis
- Finance Act 2013, Schedule 45
The three-part structure
HMRC applies the SRT as a sequence. You check the automatic overseas tests first, then the automatic UK tests, and you only reach the sufficient ties test if neither side has already decided the year.
Automatic overseas tests can make you non-UK resident without any ties analysis. If you were UK resident in one or more of the previous three tax years, spending fewer than 16 days in the UK can be enough. If you were not UK resident in any of the previous three tax years, the threshold is fewer than 46 UK days. There is also a full-time overseas work test with its own UK day and UK workday limits.
Automatic UK tests come next. The clearest is 183 days or more in the UK in the tax year. A UK home can also create automatic residence under detailed conditions below 183 days, and so can full-time work in the UK over a qualifying period.
The sufficient ties test decides everything left over. HMRC looks at UK ties such as family, accommodation, work, and prior time spent in the UK, plus a country tie if you were UK resident in one or more of the previous three tax years. The underlying logic is simple: the more UK ties you have, the fewer UK days you can spend before becoming resident.
Why prior residence changes the answer
Prior residence status decides which sufficient ties table applies to you, and the two tables are far apart.
- Resident in one or more of the previous three tax years: the table can start as low as 16 to 45 UK days for someone with four ties.
- Not resident in any of the previous three tax years: the tables do not start until 46 UK days and generally require more ties.
Two people with identical travel can land on opposite sides of the line purely because one of them was recently UK resident.
Where the day count is not obvious
- The year is the UK tax year, not January to December. A pattern that looks harmless on a calendar year can still matter.
- Days are generally counted by presence in the UK at the end of the day, but deeming and exceptional-circumstances rules can change the practical total.
- Ties are defined, not intuitive. HMRC gives each tie its own conditions in the sufficient ties tables, so this is not a gut-feel exercise.
- The SRT is step one, not the whole answer. Split year treatment, dual residence, and treaty tie-breakers can still change your position afterwards.
- Visitor rules are a separate framework. A Standard Visitor stay pattern and UK tax residence answer different questions.
What changed in April 2025
The SRT itself did not change. What changed is what happens once you are found to be UK resident. From 6 April 2025 the remittance basis of taxation for non-domiciled individuals was abolished and replaced by the Foreign Income and Gains (FIG) regime. Individuals who have been non-UK resident for at least 10 consecutive tax years immediately before becoming UK resident can elect to shelter their foreign income and gains from UK tax for their first four tax years of UK residence. After that four-year window closes, those foreign income and gains are taxed in the usual way. HMRC's current guidance is in RDR1 and the manual sections now carrying the "Residence and FIG Regime Manual" label.
If you have recently become UK resident after a long period overseas, previously relied on the remittance basis, or are inside the four-year window, the SRT answer is still step one, but the consequence of that answer is materially different from what the old non-dom rules produced.

Is the UK a simple 183-day rule?
No. 183 days or more in a tax year makes you resident automatically, but you can also become resident well below 183 days through a UK home, full-time UK work, or enough UK ties under the sufficient ties test.
How are UK days counted?
Generally by where you are at midnight: a day counts if you are in the UK at the end of it. Deeming and exceptional-circumstances rules can adjust the total, and the year is the UK tax year, 6 April to 5 April.
What is the FIG regime?
From 6 April 2025 the remittance basis was replaced by the Foreign Income and Gains regime: new UK residents who were non-resident for the previous 10 tax years can shelter foreign income and gains for their first four years of residence.
