Moving to the UK

When should I arrive in the UK so I do not accidentally become tax resident this year?

The short answer

Count backwards from 5 April, the end of the UK tax year. If you were not UK resident in any of the three previous tax years, spending fewer than 46 days in the UK before the year ends makes you automatically non-resident for that year, so an arrival date that leaves you under that ceiling keeps the year clean. From 46 days upwards your ties decide the answer, and from 183 days you are resident automatically. If you will clearly be resident from the moment you land, the aim shifts from avoiding residence to securing split-year treatment so only the post-arrival part of the year is taxed.

The UK tax year runs 6 April to 5 April and residence is decided for each tax year, so the same arrival date can be safe or fatal depending on which side of 6 April it falls.
Arrivers (not UK resident in any of the three prior years) are automatically non-resident with fewer than 46 UK days in the tax year.
Between 46 and 182 days, ties decide: an arriver needs all 4 ties to be resident at 46 to 90 days, 3 ties at 91 to 120 days and 2 ties at 121 to 182 days.
Watch the automatic UK tests: 183 days always makes you resident, and having your only home in the UK with just 30 days of presence in it can too.
If residence is unavoidable, split-year treatment can tax you only from arrival, but a split year still counts as a full year of the four-year FIG window, so late-year arrivals waste relief.

The 46-day rule sets the safe arrival date

For most people planning a move, the controlling number is 46. If you were not UK resident in any of the three preceding tax years, the automatic overseas test makes you non-resident for any year in which you spend fewer than 46 days in the UK, and a UK day is broadly one where you are present at midnight. Arrive in late February and you cannot realistically breach it; arrive in November and you need to manage the diary. Above 46 days you fall to the sufficient ties test, where an arriver becomes resident at 46 to 90 days only with all four ties (family, accommodation, work and the 90-day tie), at 91 to 120 days with three, and at 121 to 182 days with two. The full tests and bands are in our Statutory Residence Test guide.

Two automatic UK tests can override the day count

Staying under 183 days is necessary but not sufficient. Spending 183 or more days in the UK makes you resident with no further analysis, and the UK home test can do the same at far lower counts: a UK home held for 91 consecutive days in which you are present on at least 30 days, with no overseas home (or fewer than 30 days spent in one), makes you resident automatically. So the pre-move pattern matters. Taking a UK flat months before you fully relocate, while giving up your home abroad, is precisely how people become resident a year earlier than intended. Full-time UK work is the third automatic route in, which catches anyone who starts a UK job early in the move.

If residence is coming anyway, time it for the reliefs

When the move is definite, the better question is which tax year should be your first resident year. Split-year treatment applies automatically if you meet one of the five arriver cases, taxing you as UK resident only from your arrival date, so pre-arrival foreign income and gains generally stay outside UK tax. But if you qualify for the four-year FIG regime after 10 consecutive non-resident years, remember that a split year of arrival counts as a full year of your window: land in March and you spend an entire FIG year on a few weeks. For FIG claimants an arrival shortly after 6 April uses the window best, while anyone selling assets or collecting large foreign income does well to let those arise before the UK part of the year begins.
