The automatic UK home test is the one that catches people
People fixate on staying under 183 days, but the second automatic UK test works at far lower numbers. If you have a home in the UK for at least 91 consecutive days, are present in it on at least 30 days in the tax year, and have no overseas home (or spend fewer than 30 days in any overseas home that year), you are UK resident automatically, and ties never enter into it. The practical defence is the overseas side of the equation: a real home abroad that you actually use for 30 or more days in the year takes the test off the table. The full sequence of automatic tests is set out in our Statutory Residence Test guide.
The accommodation tie shrinks your day budget
Once past the automatic tests, the sufficient ties test weighs your UK days against up to five ties, and a kept house almost always supplies one: accommodation available to you for a continuous period of at least 91 days in which you spend at least one night. For leavers, those UK resident in any of the three prior tax years, the bands are tight. At 16 to 45 days you need 4 ties to be resident; at 46 to 90 days, 3 ties; at 91 to 120 days, 2 ties; and from 121 days a single tie suffices. A recent leaver who keeps the house, has the 90-day tie from past years and spends more midnights in the UK than anywhere else (the country tie) is already at three ties, so a couple of months of UK visits can flip the year. Leaving the UK cleanly is mostly an exercise in managing exactly this arithmetic.
How to keep the house and the non-residence
The workable pattern is a genuine home overseas that you demonstrably live in, a UK day count planned against your true tie count rather than the 183-day folklore, and contemporaneous records: travel logs, boarding passes and evidence of nights actually spent in each home, because the burden of proof sits with you. If you are leaving partway through a year, split-year treatment determines when the overseas part starts, and the departure-year planning is worth doing before you book flights, not after. We run fixed-fee residence reviews that put a defensible number on your safe UK days, and a free 30-minute clarity call is the place to start.
