For SRT purposes a UK day usually means being in the UK at the end of the day.
This switches between the inbound and outbound sufficient ties tables.
The simplified calculator treats this as a direct yes/no input. HMRC has detailed hour and break rules.
Broadly: a UK home available for a 91-day period, at least 30 days present, and no overseas home with 30+ days present.
This is the automatic UK work test: full-time UK work over a qualifying 365-day period.

Set your UK day count and answer the automatic test questions. The calculator will show the first SRT route that decides the year.
Decision path
Inbound tableIf none of the automatic tests decide the result, the UK ties table decides the year.
- Split-year treatment is outside this calculator.
- Exceptional circumstances and deemed UK days can alter the day count.
- The overseas and UK work tests have detailed hour-calculation rules.
- This is a screening tool, not tax advice.
How the SRT calculator reaches a result
The calculator follows the order set out in HMRC guidance: 183 UK days, automatic overseas tests, automatic UK tests, and finally the sufficient ties table.
If you meet an automatic overseas test, the result is likely non-UK resident unless the 183-day automatic UK rule already applies.
If no automatic overseas test applies, 183 UK days, the UK home test, or sufficient UK work can make you UK resident.
If the automatic tests do not settle it, UK ties are compared with the relevant day-band threshold for inbound or outbound cases.
