|---| | Country | United Kingdom | | SRT effective | 6 April 2013 | | Tax year | 6 April – 5 April | | Primary legislation | Finance Act 2013, Schedule 45 | | Tax authority | HMRC (gov.uk/tax-foreign-income/residence) | | Official guidance | RDR3 Statutory Residence Test | | Verified by | Live status: https://openaccountants.com/skills/uk-statutory-residence-test |
The SRT applies in this order:
If ANY of these apply, the individual is not UK resident for the year:
| Test | Condition |
|---|---|
| AOT 1 | Not resident in UK in ANY of the 3 previous tax years AND present in UK for fewer than 46 days |
| AOT 2 | Resident in UK in at least 1 of the 3 previous tax years AND present in UK for fewer than 16 days |
| AOT 3 | Works full-time overseas (≥35 hrs/week average), present in UK for fewer than 91 days, and works in UK for fewer than 31 days |
"Day in UK" = present at midnight in the UK.
If ANY of these apply, the individual is UK resident (unless an AOT also applies — AOTs take precedence):
| Test | Condition |
|---|---|
| AUT 1 | Present in UK for 183 days or more |
| AUT 2 | Only home is in the UK (UK home available for ≥91 days and used at least once; no overseas home available) |
| AUT 3 | Works full-time in the UK for ≥365 days with no significant break (≥31 continuous days without UK work) — at least one day falls in the tax year |
| AUT 4 | Dies in the tax year having been UK resident in prior year AND present ≥183 days |
If neither automatic test determines residency, apply the Sufficient Ties test. Count UK ties present, then check the threshold based on days in UK and prior residence status.
The five ties:
| Tie | Condition |
|---|---|
| Family tie | Spouse/partner/child under 18 is UK resident |
| Accommodation tie | Accessible UK accommodation available for ≥91 days; used at least once |
| Work tie | Works in UK for ≥40 days (3+ hours counts as a working day) |
| 90-day tie | Present in UK for >90 days in either or both of the 2 preceding tax years |
| Country tie | Present in UK more days than any other country (applies only to PREVIOUSLY UK resident individuals) |
Thresholds:
For individuals previously UK resident (resident in ≥1 of last 3 years):
| Days in UK | Ties needed to be UK resident |
|---|---|
| Fewer than 16 | Always non-resident (AOT 2) |
| 16 – 45 | 4 or more ties |
| 46 – 90 | 3 or more ties |
| 91 – 120 | 2 or more ties |
| 121 – 182 | 1 or more ties |
| 183+ | Always resident (AUT 1) |
For individuals not previously UK resident (not resident in any of last 3 years):
| Days in UK | Ties needed to be UK resident |
|---|---|
| Fewer than 46 | Always non-resident (AOT 1) |
| 46 – 90 | 4 or more ties |
| 91 – 120 | 3 or more ties |
| 121 – 182 | 2 or more ties |
| 183+ | Always resident (AUT 1) |
In the year of arrival in or departure from the UK, the year may be split:
In a split year, UK is only taxed on income/gains arising in the UK part of the year.
A "day in the UK" is any day you are present in the UK at midnight. However, a day is NOT counted if you are in transit (passing through without staying the night) and your journey is to/from an overseas destination.
Exceptional circumstances: days forced by exceptional circumstances (hospitalisation, death of relative, national emergency) may be disregarded (up to 60 days in certain tests).
Working paper only. The SRT involves detailed day-counting. Maintain a contemporaneous travel log. Get HMRC clearance (SRT check) if uncertain about status.
