What is the Statutory Residence Test?

The SRT is HMRC's official method for determining UK tax residence. It uses a series of tests based on your days spent in the UK, your ties to the UK, and your work patterns to determine whether you are UK resident for tax purposes.

This calculator guides you through the test step-by-step, following the exact criteria in HMRC's RDR3 guidance document.

What you'll need

  • Records of your travel dates to and from the UK
  • Knowledge of your residence status in the previous 3 tax years
  • Information about your UK ties (family, accommodation, work)
