Automatic overseas test 2026: fewer than 16, 46 or 91 days in the UK

The automatic overseas tests are the quickest way out of UK tax residence, and they come first in the Statutory Residence Test because meeting any one of them ends the inquiry for that tax year. Nothing else is looked at: no ties, no family, no home, with one exception that HMRC states plainly, which is that 183 days or more in the UK make you resident, with no exceptions. There are three tests for living people, plus two more that apply only in the year of death. The first two are pure counts of days and depend only on whether you were UK resident in any of the 3 previous tax years, and a split year counts as a full year of residence there. The third is for people working full-time abroad. It allows more days but adds an hours calculation and a condition about breaks, and this is where most mistakes happen, because people stop reading at the number 90.

The first two tests: a plain count of midnights

Which line you are on depends on three past years, tested one by one. Someone who left the UK in 2024 stays on the first line for several years, even if they have long since made a home elsewhere. HMRC's manual adds that the first test cannot be used for a person who dies in the year. The deeming rule can raise your day count here: for someone with 3 ties who was resident recently, UK days without a midnight beyond the first 30 are added to the total, and that total is what you compare with 16.

Days spent in the UK because of exceptional circumstances may be left out, up to a limit of 60 days in a tax year. HMRC stresses that this is a limit, and not an allowance you can claim as of right. The guide to UK days explains how each day counts.

The third test: 90 days, 30 workdays, and four conditions together

This is the test for people who actually work abroad, employed or self-employed. Voluntary work does not qualify, and neither does a job on board a vehicle, aircraft or ship if at least 6 of the year's cross-border trips begin or end in the UK. RFIG20140 sets four conditions, and all must hold across the whole tax year:

GOV.UK sums this up as fewer than 91 days, no more than 30 of them working. RFIG20720 adds a useful detail: the deeming rule does not apply to the limit of days under this third test, so your UK midnights alone are what counts there.

The 35-hour calculation, step by step

RFIG20150 gives five steps, and contract hours play no part: it is always the hours actually worked.

First, identify the disregarded days: every day in the year with more than 3 hours of work in the UK, even if you also worked abroad that day. Second, add up all hours worked overseas in the year, for every job, leaving out hours on disregarded days. That is your net overseas hours. Third, start from 365 days, or 366 if the year includes 29 February, then subtract the disregarded days, any allowed gaps between jobs, and other allowed days such as annual, sick or parenting leave. That is the reference period. Fourth, divide the reference period by 7 and round down to a whole number, unless the answer is below 1, in which case round up to 1. Fifth, divide net overseas hours by that number. You need 35 or more.

HMRC's worked example is MayLing, who changes employer in Italy during the year and spends no time in the UK:

The gap rule is where it bites. A gap between two employments can be subtracted only up to 15 days for a single gap and 30 days in total, and only if you did no work during it. The self-employed get no deduction at all for gaps between periods of self-employment. Lose those days from the deduction and your average falls.

The 31-day break that catches contract workers

A significant break means at least 31 days go by without a single day on which you work more than 3 hours overseas, or would have done but for annual, sick or parenting leave. HMRC's example is Alex. His Dubai contract ends on 28 February 2017, he comes back to the UK on 1 March, and his new job in Saudi Arabia starts on 7 April. Between 1 March and 5 April there are 36 days of no overseas work, so he has a significant break and fails the third test for that tax year, even though he has worked abroad throughout, apart from those weeks. He must then look at the other two tests.

What the counter does, and what it leaves to you

Enter your trips and the counter sets your UK midnights against the limits for your history, working from the tax year you choose. It keeps deemed days out of the 91-day limit, as the manual requires, and adds them for the first two tests where they apply. It does not compute your hours or your breaks. For those it asks you to say whether you meet the full-time conditions, and to give your UK workdays. Run the five steps above yourself first, and keep the timesheets that support them.

The two most useful results are the count against your limit and the margin that remains. With two short family visits, the default trips above show a person well under 16 days. Add a week and the first test goes, which sends you to Table A of the sufficient ties test, where 4 ties would be enough to make you resident. If you meet no overseas test, carry on with the full Statutory Residence Test calculator. To keep your midnights in order across the year, the Taxlag app does the tally for you.

What an overseas test does not do

Passing one of these tests makes you non-UK resident under UK law for that tax year, and nothing more. It does not make you resident anywhere else. It does not cancel tax on UK income, which GOV.UK says can still arise for a non-resident, for example on rent from a UK property. It does not by itself protect you for later years, because each year is tested again. And it does not stop the temporary non-residence rules if you return within 5 years. For someone moving in the middle of a tax year, the question is usually a different one: see split year treatment, where Case 1 uses a shorter version of the same hours test.
