The Statutory Residence Test, explained.

The Statutory Residence Test is applied in sequence, and you stop at the first test that gives an answer. First the automatic overseas tests: if you meet one, you are non-resident and nothing further applies. Only if none is met do you move to the automatic UK tests. Only if none of those is met do you reach the sufficient ties test.

Most poor outcomes come from starting in the middle, usually at the day count, and never checking whether an automatic UK test was already met.

These are the exits. In broad terms they cover people who spend very few days in the UK in the year given their recent residence history, and people who work full time overseas with limited UK days and limited UK workdays.

The full-time work abroad route is the one founders most often assume they meet and most often fail, because it carries conditions on the number of UK workdays and on significant breaks from overseas work. A founder who keeps chairing UK board meetings is rarely working full time overseas in the way the test means it.

These are the traps. Spending 183 days or more in the UK makes you resident, but so can having a home in the UK that you use, in circumstances where you have no equivalent overseas home you use enough. So can working full time in the UK over a defined period.

The home test catches people who move abroad but keep a UK property available and spend enough nights in it. Selling nothing and letting nothing is a common, expensive default.

If neither set of automatic tests decides it, residence turns on how many UK ties you have against how many days you spend here. The ties considered are family, accommodation, work, 90 days in either of the two previous tax years, and, for those recently resident, whether the UK is the country you spend most days in.

The more ties you keep, the fewer days you can spend. Someone leaving the UK with a spouse still here, a property available, and UK work will hit residence at a day count that looks surprisingly low. Someone who has cut those ties has considerably more room.

A day generally counts if you are in the UK at the end of it, at midnight. There are specific rules for transit, for exceptional circumstances, and a deeming rule that can pull in days where you were present but not at midnight if you have enough UK ties and a recent residence history.

Keep contemporaneous records: boarding passes, calendars, card data. A reconstructed day count two years later is not evidence, it is a negotiating position.

A tax year is normally residence-in-full or non-residence-in-full, but split year treatment can divide the year you leave or arrive into a UK part and an overseas part where specific cases apply. Split year treatment affects how the year is taxed. It does not change whether you are resident for the year.

If you leave, become non-resident, and then return within the temporary non-residence window, gains realised while away can be brought back into charge in the year you return. Departure planning that ignores the return date is only half done.

For a relocating founder we model the departure year and the following two or three years together: intended day counts, which ties survive the move, the treatment of any UK property, the timing of share disposals, and the earliest safe return date. The output is a schedule the client can actually live by, not a conclusion.
