United Kingdom tax residency rules

Threshold: 183 days · Statutory Residence Test · Tax year (UK: Apr 6 – Apr 5)

The UK Statutory Residence Test (SRT) is a three-stage residency test: automatic non-resident tests, automatic resident tests, then a sufficient-ties test. The UK tax year runs 6 April – 5 April, not the calendar year. Day counts matter at every stage, with subtleties around midnight presence, transit days, and the 'deeming' rule.

  • 183 days in the UK tax year = automatic UK resident.
  • 16 UK days = automatic non-resident if UK-resident in any of the prior 3 tax years.
  • Sufficient-ties test combines UK ties (family, accommodation, work, 90-day, country) with day count via a published matrix.
