Statutory Residence Test UK

The UK Statutory Residence Test (SRT) sits in Schedule 45 of Finance Act 2013 and HMRC RDR3 guidance, operating through three sequential parts: the automatic overseas tests, the automatic UK tests, and the sufficient ties test. The test determines an individual's UK tax residency for each tax year, replacing the prior case-law residency tests from 6 April 2013. The April 2025 abolition of the remittance basis under Finance Act 2024 has shifted attention to the SRT as the central determinant of UK tax exposure, with HMRC compliance activity reportedly expanding in this area. The split-year treatment rules in Cases 1 to 8 of Part 3 of Schedule 45 cover the transition rules.

The SRT applies in three sequential parts

The Statutory Residence Test operates through three sequential parts: the automatic overseas tests (which, if any apply, conclude the individual is not UK resident), the automatic UK tests (which, if any apply and no overseas test does, conclude the individual is UK resident), and the sufficient ties test (applied only if neither the automatic overseas nor automatic UK tests apply). The structure is set out in Schedule 45 of Finance Act 2013 and HMRC RDR3 guidance. The sequential approach ensures that simple cases are resolved at the first stage, with only the more complex cases reaching the sufficient ties test.

An individual who is non-resident under any automatic overseas test cannot be UK resident under that year's SRT. An individual who is UK resident under any automatic UK test (and not under any automatic overseas test) is UK resident. The sufficient ties test applies only to the residual population not resolved by the automatic tests, with the number of UK ties combined with UK days present determining the residency outcome.

The automatic overseas tests cover three specific scenarios

The automatic overseas tests cover three specific scenarios: presence in the UK for fewer than 16 days where the individual was UK resident in one of the previous three tax years; presence in the UK for fewer than 46 days where the individual was not UK resident in any of the previous three tax years; and full-time work overseas with limited UK presence under specific conditions. The 16-day rule is the most commonly applied automatic overseas test for individuals leaving the UK, providing a clear bright line for individuals who have substantially departed. The 46-day rule provides the parallel for individuals who have been outside the UK system entirely in the recent period.

The full-time work overseas test requires the individual to work full-time abroad (sufficient hours, broadly 35 hours per week averaged over the tax year), spend fewer than 91 days in the UK, and work for fewer than 31 days in the UK where each working day involves more than three hours of work. The mechanism is operationally complex and HMRC has published detailed guidance on the day-counting and hours-counting rules.

The automatic UK tests cover three further scenarios

The automatic UK tests cover three further scenarios: presence in the UK for 183 days or more in the tax year; UK home test (UK home, present for at least 30 days, with no overseas home or limited overseas home presence); and full-time work in the UK. The 183-day rule is the historic backstop for UK residency and continues to operate as a bright-line test under the SRT. An individual present in the UK for 183 days or more in a tax year is UK resident under that year's SRT, regardless of other factors.

The UK home test is operationally complex. An individual is UK resident under this test if they have a UK home for any period of 91 consecutive days, present there for at least 30 days in the tax year, with no overseas home or with limited presence at any overseas home. The mechanism captures individuals who have a clear UK base even where their day count is modest.

The sufficient ties test combines days and ties to determine residency

The sufficient ties test applies where neither the automatic overseas nor automatic UK tests resolve the residency question, combining the number of UK ties (family, accommodation, work, 90-day, country) with the number of UK days present in the tax year to determine residency under a sliding scale. The five UK ties are: family tie (UK-resident spouse, civil partner, or minor child), accommodation tie (UK accommodation available for a continuous period of 91 days), work tie (more than 40 days of UK work), 90-day tie (90+ UK days in either of the prior two tax years), and country tie (more time spent in the UK than any other country).

The number of UK ties required to establish residency depends on whether the individual was UK resident in any of the prior three tax years (arriver vs leaver position). The sliding scale is set out in Tables 1 and 2 of Schedule 45 of Finance Act 2013. An arriver requires more ties at any given day count to be UK resident, reflecting the policy intention of facilitating short visits without triggering residency.

Day-counting follows specific HMRC rules with limited exclusions

UK day-counting follows specific HMRC rules under Schedule 45 of Finance Act 2013, with a day in the UK generally being a day where the individual is present in the UK at midnight, with limited exclusions for transit passengers and the exceptional circumstances provision. The transit exclusion applies where the individual passes through the UK on the way to another destination, with the day not counted provided certain conditions are met (no business meetings, no overnight stop other than for transit). The exceptional circumstances provision allows up to 60 days to be disregarded where the individual was unable to leave the UK due to exceptional circumstances beyond their control.

The COVID-19 pandemic period saw HMRC issue specific guidance on the exceptional circumstances provision, with the 60-day cap remaining in place. The HMRC RDR3 guidance includes worked examples of day-counting in various scenarios. The day-counting infrastructure is the operational backbone of the SRT and accurate record-keeping by the individual is essential.

Split-year treatment covers transition periods

Split-year treatment applies under Part 3 of Schedule 45 of Finance Act 2013 to individuals arriving in or leaving the UK during a tax year, treating the year as two parts: a UK part (taxed as resident) and an overseas part (taxed as non-resident). The treatment applies under one of eight cases set out in Part 3, each covering a different scenario (Cases 1 to 3 for individuals leaving, Cases 4 to 8 for individuals arriving). The split-year cases interact with the automatic SRT framework; an individual must first be UK resident under the SRT for the full tax year, and then qualify for split-year treatment under one of the eight cases.

The split-year mechanism is operationally important because the alternative (taxing the individual as resident for the full year, including periods before arrival or after departure) would produce harsh outcomes for individuals making genuine cross-border moves. HMRC RDR3 guidance covers each of the eight cases in detail, including the specific conditions and operational rules.

The April 2025 non-dom reform increased SRT compliance attention

The April 2025 abolition of the remittance basis under Finance Act 2024 has increased HMRC compliance attention on the Statutory Residence Test, with the underlying residency determination now driving more of the UK tax exposure than under the prior non-dom regime. The reform replaced the remittance basis with a new four-year foreign income and gains regime for new UK residents, with longer-term UK residents now taxed on worldwide income and gains regardless of remittance. The SRT determines whether an individual is UK resident in the first place and therefore in scope for the new regime.

HMRC compliance teams have reportedly been reviewing historic residency claims, with the Treasury Committee hearing evidence on the operational impact of the reform. The Statutory Residence Test remains the central determinant of UK tax exposure for internationally mobile individuals, with the post-April 2025 framework placing increased weight on accurate application of the test.

What is the UK statutory residence test?

The Statutory Residence Test (SRT) is the framework introduced by Finance Act 2013 for determining UK tax residency. It operates through three sequential parts: automatic overseas tests, automatic UK tests, and the sufficient ties test, set out in Schedule 45 of Finance Act 2013 and HMRC RDR3 guidance.

Am I UK resident for tax?

Residency is determined under the Statutory Residence Test. Start with the automatic overseas tests (if any applies, you are not UK resident). If none applies, check the automatic UK tests. If none applies, apply the sufficient ties test, combining UK ties with UK days present. The HMRC RDR3 guidance and the SRT online questionnaire provide operational support.

What is the UK tax residency test for arrivers?

An arriver is an individual who was not UK resident in any of the previous three tax years. Arrivers face a more permissive sliding scale in the sufficient ties test (requiring more UK ties at any given day count to be resident) than leavers, reflecting the policy intention of facilitating short visits before residency triggers.

What is the SRT UK tax 183-day rule?

The 183-day rule is the second automatic UK test: presence in the UK for 183 days or more in the tax year makes the individual UK resident under the SRT, regardless of other factors. It is the historic backstop for UK residency, retained in the statutory framework.

How does split-year treatment work?

Split-year treatment under Part 3 of Schedule 45 of Finance Act 2013 treats a UK tax year as two parts (UK part taxed as resident, overseas part taxed as non-resident) for individuals arriving in or leaving the UK during the year. The treatment applies under one of eight cases, each covering a specific scenario with detailed conditions.

How has the April 2025 non-dom reform affected SRT?

The April 2025 abolition of the remittance basis under Finance Act 2024 has shifted attention to the SRT as the central determinant of UK tax exposure. HMRC compliance teams have reportedly expanded reviews of historic residency claims, with the SRT providing the operational framework for determining whether an individual is UK resident and therefore in scope.
