UK Day Limits for Tax Residency

How many days you can spend in the UK before becoming tax resident depends on two things: whether you are a leaver or arriver, and how many UK ties you have. Use the tables below to find your limit.

How to read these tables

  1. Find your row: the band that includes your total UK days (counted using the midnight rule - a day counts if you are in the UK at midnight).
  2. Find your column: the number of UK ties you have (family, accommodation, work, 90-day, country).
  3. The cell shows whether the SRT indicates Resident or Non-resident.

Leaver = UK resident in one or more of the previous 3 tax years. Arriver = not UK resident in any of the previous 3 tax years. Arrivers are not assessed against the country tie (maximum 4 ties).

Leavers (previously UK resident)

Leavers are assessed against all 5 ties. They face stricter thresholds - fewer days are required to trigger residency at higher tie counts.

Arrivers (not previously UK resident)

Arrivers are assessed against 4 ties only (country tie does not apply). They have more generous day thresholds than leavers.

Automatic tests apply first. If you spent fewer than 16 days in the UK (leaver) or fewer than 46 days (arriver with no UK residence in the previous 3 years), you are automatically non-resident - ties do not matter.

183+ days = always resident, regardless of tie count or leaver/arriver status.

Based on HMRC RDR3 Table A (leavers) and Table B (arrivers). Updated for the 2025/26 tax year.
