Am I UK resident?

The UK Statutory Residence Test decides whether you pay UK tax on your worldwide income, and it turns on day counts, your work pattern, and your ties to the UK. Answer a few questions for an instant, plain-English indication, with the deciding test and the full reasoning shown.

Your days & history

The UK tax year runs 6 April to 5 April.

Days in the UK this tax year

Count each day you were in the UK at midnight (the end of the day).

UK workdays this tax year (optional)

Days you did more than 3 hours of work in the UK. Drives the work tie (40+ days).

Were you UK resident in any of the last 3 tax years?

This sets whether you're treated as a “leaver” or an “arriver”. It changes the day thresholds.

UK days, last tax year (optional)

Used for the 90-day tie.

UK days, two years ago (optional)

Used for the 90-day tie.

How it works

The SRT, applied in the right order

This calculator follows the Finance Act 2013 framework HMRC uses (RDR3). It gives you an instant indication, not formal advice.

Automatic tests first

We apply the automatic overseas tests, then the automatic UK tests. The first one that fires decides your status.

Then the sufficient ties test

If no automatic test settles it, we count your UK ties against the day band for arrivers and leavers.

A full reasoning trail

You get the deciding test, your ties met versus needed, and an auditable step-by-step of how we got there.

This is an indication, not advice. The SRT has nuances this tool does not fully model: split-year treatment, the only-home and full-time-work conditions, deemed days, and exceptional circumstances can all change the outcome. Your figures are processed instantly and are not stored unless you choose to email yourself the result.

For a definitive position (and the planning that follows from it), speak to a qualified adviser about your specific facts.
