Begin with the tax year and the adjusted day count
The Statutory Residence Test considers each UK tax year separately. HMRC's RDR3 guidance says that if you have been in the UK for 183 days or more, you will be UK resident and there is no need to consider any other tests. That statement depends on the statutory day-count rules, not an unreviewed total of visits.
A day is ordinarily counted when the person is present in the UK at the end of it. Transit, exceptional circumstances and the deeming rule can alter particular counts under defined conditions. A confirmed adjusted 183-day result can therefore settle the first automatic UK test even when generic complex-case flags exist; uncertainty about the adjustment itself still requires review.
Keep the statutory sequence intact
For an ordinary full-year review below the confirmed 183-day point, use the ordered path: automatic overseas tests, then automatic UK tests, then the sufficient ties test. Meeting an automatic overseas test ends that full-year path as non-resident. If none applies, meeting an automatic UK test establishes residence under the SRT.
Only when no automatic overseas or automatic UK test applies does the sufficient ties test combine UK days with qualifying connections. Reordering the stages can produce a false answer. A ties score cannot override an automatic overseas result, and a low ties count cannot displace a met automatic UK test.
Prior residence changes several branches
The first two automatic overseas tests divide according to residence in the three preceding tax years. A person resident in one or more of those years uses the fewer-than-16-day branch; a person resident in none uses the fewer-than-46-day branch. The sufficient ties tables preserve the same prior-residence distinction with different bands.
Do not infer the prior-year answer from nationality, domicile, a visa, or a current address. It requires the relevant residence status for each preceding tax year, including any rules that applied then. If that history is unknown, the calculator can show branches but should not choose one as a personal conclusion.
Move complex cases to a separate review
Full-time overseas and UK work tests require hours, qualifying periods, significant-break rules and other statutory steps. Deceased-person tests, transit, relevant jobs aboard vehicles, aircraft or ships, and exceptional-circumstance claims also need facts beyond ordinary dates. Roam Window does not convert a warning about one of those areas into a residence result.
Split-year treatment is considered only after full-year UK residence and has eight cases and priority rules. Treaty residence is another layer and can affect how domestic residence is treated for relevant tax purposes. Neither layer is resolved by the ordinary sequence, and no guide determines filing obligations, liability or a final personal tax position.
- Confirm the tax year and the applicable day count.
- Apply automatic overseas, automatic UK, then sufficient ties in order.
- Escalate work, transit, worker, deceased-person, treaty and split-year facts.
