UK residence status calculator
Leaving the UK is the easy part. Knowing whether you've actually left UK tax behind is a test — a real one, written into law. Run it here.
This free calculator runs all three parts of HMRC's Statutory Residence Test, in order — the automatic overseas tests, the automatic UK tests, then the sufficient ties test — to indicate whether you're UK tax resident for a tax year, and how many UK days you can spend as a non-resident. It runs in your browser and cites HMRC RDR3. General guidance, not advice (HMRC RDR3; 2026/27).
Your answer is on screen before any email field.
Most "SRT calculators" are thin single-screen counters. This one walks HMRC's mandatory order, stops at the first definitive answer, and names the rule that decided it — with the source next to it.
Are you still UK tax resident?
Answer a few questions about your days and ties. We'll show your result on screen — and the exact rule behind it.
- No email required to see your answer
- Every result linked to its HMRC source
- Runs in your browser, no upsell
Three worked scenarios
Each is an illustrative example — not a guarantee. Real outcomes depend on your exact facts and HMRC's assessment.
Leaver, very few days
Theo bounces between countries with a laptop. This tax year he spends 9 days in the UK, was UK resident in at least one of the last 3 years, and has no full-time job anywhere.
Non-residentDecided at the first automatic overseas test — a leaver with fewer than 16 UK days is non-resident, before ties even matter (HMRC RFIG20120).
Full-time work overseas
Aisha works ~40 hours a week in Dubai, did UK work on 12 days, had no significant break, and spent 74 days in the UK visiting family.
Non-residentDecided at the third automatic overseas test — full-time work overseas, fewer than 31 UK working days, fewer than 91 UK days, no significant break (HMRC RFIG20140).
Leaver, mid-band on ties
Marco moved to Lisbon but kept a UK flat and still does UK client work. He spends 80 UK days and has 3 ties (accommodation, 90-day, work).
UK tax residentIt goes to the ties test: 46–90 days needs 3+ ties to be resident, and Marco has 3 (HMRC RFIG20520). He'd need to drop a tie or cut days below 46.
What does this UK residence status calculator tell you?
Direct answer: It tells you whether, on your own day counts and ties, the Statutory Residence Test points to you being UK tax resident or non-resident for a tax year — and which of the test's three stages decided it. Mode B flips the question: given your ties, how many UK days you can spend and stay non-resident (HMRC RDR3; RFIG20520; 2026/27).
The calculator does one thing the thin counters don't: it runs the SRT in HMRC's mandatory order, stops at the first definitive answer, and names the rule that decided your status — with the source next to it. It's general guidance, not advice — an estimate, not a ruling.
How does the test work — and how does the calculator follow it?
Direct answer: The SRT runs in a fixed sequence and stops at the first stage that gives an answer: automatic overseas tests (meet any one → non-resident), then automatic UK tests (meet any one → resident), then the sufficient ties test. The calculator walks exactly that order (HMRC RDR3; RFIG20110; 2026/27).
- Automatic overseas tests — meet any one and you're non-resident, stop. Fewer than 16 UK days as a leaver; fewer than 46 as an arriver; or genuine full-time work overseas with limited UK days (HMRC RFIG20120–20140).
- Automatic UK tests — meet any one (and no overseas test) and you're resident, stop. 183+ UK days; your only home in the UK; or full-time work in the UK (HMRC RFIG20360, RFIG20380).
- Sufficient ties test — only if neither stage above resolves it. Count your UK ties and read them against your UK days in the leaver or arriver table. The more days, the fewer ties it takes to be resident (HMRC RFIG20520).
Is using this calculator — and becoming non-resident — legal?
Direct answer: Yes. Non-residence is a status you qualify for in statute — the Statutory Residence Test (Finance Act 2013, Schedule 45) — openly, and report to HMRC on a P85 or your tax return. It is the opposite of evasion: you're not hiding income or residence, you're meeting published rules and telling HMRC you've left (HMRC RDR3; 2026/27).
This calculator is an estimate of how those rules apply to your facts. It doesn't file anything, doesn't store your numbers, and doesn't replace the official route or a qualified adviser. Read the whole legitimate journey in How to stop being a UK tax resident.
Common questions
How many days can I spend in the UK without being tax resident?
It depends on your ties and history. A leaver (UK-resident in 1+ of the last 3 years) is automatically non-resident on fewer than 16 UK days; up to 45 days needs 4+ ties to be resident; 46–90 days, 3+ ties; 91–120 days, 2+ ties; 121–182 days, 1+ tie; 183+ days is always resident. Count nights. (HMRC RDR3; RFIG20520; 2026/27.)
What counts as a day spent in the UK for the residence test?
A day counts if you are present in the UK at the end of the day (midnight) — so count nights, not days. Transit days where you arrive and leave the next day without UK activities generally don't count. The deeming rule can add back days you were here without staying overnight. (HMRC RFIG20710; RFIG20720; 2026/27.)
What is the Statutory Residence Test?
The Statutory Residence Test (SRT) is the UK's legal test for tax residence, in force since 6 April 2013. It runs in a fixed order: automatic overseas tests (any one met → non-resident), then automatic UK tests (any one met → resident), then the sufficient ties test, which combines your UK days with your number of UK ties. (HMRC RDR3; RFIG20110; 2026/27.)
How do I stop being a UK tax resident?
Pass the Statutory Residence Test as non-resident for a full tax year: meet one automatic overseas test (most leavers — fewer than 16 UK days), or keep your UK days and ties low enough under the sufficient ties test. If you leave mid-year, split-year treatment may split that year into a UK part and an overseas part. Count nights, not days. (HMRC RDR3; FA 2013 Sch 45 Part 3; 2026/27.)
Is this calculator free, and does it store my data?
Yes, free — no gate, no paywall, no upsell. The calculator runs entirely in your browser as a React island; the numbers you enter are not stored. The only network call is the optional “email me my result” form. (Last reviewed: May 2026.)
