Count your days against “six months” and the UK tax residency rules can catch you far earlier. The European Union's plain summary puts tax residence where you spend “more than 6 months a year” (Your Europe, accessed October 2026); the UK test can make a former resident UK resident from the 16th day.
Residents normally pay UK tax on all their income, from the UK or abroad, while non-residents pay only on their UK income. Each country defines residence in its own law, which is what tax residency means in general terms, and the Statutory Residence Test is the UK's answer. It weighs your days against your ties.
No. Spend 183 days or more in the UK in a tax year and you are resident, with no further test. Below that figure, nothing is settled.
The Statutory Residence Test has applied since 6 April 2013 and looks at each tax year, 6 April to 5 April, separately. Its answer has weighed more since 6 April 2025: HMRC describes the current system as residence-based, replacing the old domicile-based one.
183 days is the point at which the answer becomes certain, not the point at which residence starts.
You are resident if you meet at least one automatic UK test and none of the automatic overseas tests, or the sufficient ties test; otherwise you are not. HMRC reads the tiers in this order (RDR3, updated 11 June 2026).
| Tier | What it asks | Result if met |
|---|---|---|
| Automatic overseas | Very few UK days, or full-time work abroad | Non-resident |
| Automatic UK | 183 days, a UK home, or full-time UK work | Resident |
| Sufficient ties | Days set against ties | Resident |
Three automatic tests of each kind apply to most people; further tests apply only on death.
A resident under the test is also one for Article 4(1) of the UK's double taxation agreements, and HMRC notes that a US citizen remains taxable in the United States on income from any country, even when living abroad: the starting point for how the UK-US treaty treats UK residents.
HMRC puts the logic in one sentence: “The more UK ties you have, the fewer days you can spend here before you become UK resident.”
| Tie | What creates it |
|---|---|
| Family | A UK resident spouse, civil or cohabiting partner, or child under 18 (unless seen in the UK on fewer than 61 days) |
| Accommodation | A place to live available for a continuous 91 days or more and used for at least 1 night (16 at a close relative's home) |
| Work | More than 3 hours' UK work a day on at least 40 days |
| 90-day | More than 90 UK days in either or both of the 2 previous tax years |
| Country (leavers only) | The UK is where you spend the most midnights in the tax year |
Your 3 previous tax years decide which rules apply. Resident in none of them, you are an arriver, tested on four ties; resident in one or more, you are a leaver, tested on all five. The 90-day tie looks back two years, so on a plain reading it falls away only after two successive years at 90 days or fewer.
The UK counts midnights over 6 April to 5 April; the UAE's test, under Cabinet Decision No. 85 of 2022 (effective 1 March 2023), counts days or parts of a day over 12 consecutive months. Two domestic laws can therefore both say “resident”, which HMRC calls a dual resident. Where a double taxation agreement applies, its tie-breaker rules decide: that is how a tax treaty settles dual residence.
Family, accommodation, work, the 90-day tie and, for leavers only, the country tie. The more UK ties you have, the fewer days you can spend in the UK before you become resident.
The statute answers with a grid of the ties that make you resident (Finance Act 2013, Schedule 45).
| UK days in the tax year | Leaver | Arriver |
|---|---|---|
| 16 to 45 | At least 4 ties | Not resident (automatic overseas test) |
| 46 to 90 | At least 3 ties | All 4 ties |
| 91 to 120 | At least 2 ties | At least 3 ties |
| Over 120 | At least 1 tie | At least 2 ties |
Turned round, and as a reading derived from the HMRC table rather than a quotation, a leaver stays non-resident with at most 15 days with 4 or 5 ties, 45 with 3, 90 with 2, 120 with 1 and 182 with none. Two conditions apply. The days are days “spent in the UK” in the statutory sense, which for a leaver with at least 3 ties includes deemed days; and no automatic UK test is met, in particular the UK home test and full-time UK work.
Take an investor, long UK resident, who moved to Dubai during the tax year 2025 to 2026. In 2026 to 2027, his first full tax year abroad, he is a leaver, present in his Dubai home on well over 30 days and not working full-time, so at 40 to 48 UK days no automatic test settles his year. He keeps three ties: a UK resident spouse, a London flat kept available and used, and more than 90 UK days in at least one of the two previous tax years. Fewer than 40 UK work days and more midnights in the UAE rule out the work and country ties.
| Scenario | UK midnights | Deemed days | Ties | Days counted | Result for 2026 to 2027 |
|---|---|---|---|---|---|
| A. Base case | 40 | 0 | 3 | 40 | Not resident |
| B. Six more nights | 46 | 0 | 3 | 46 | Resident |
| C. 38 days of presence without a midnight | 40 | 8 (38 less the first 30) | 3 | 48 | Resident |
| D. Flat no longer available | 46 | 0 (deeming rule needs 3 ties) | 2 | 46 | Not resident (threshold: 91 days) |
The profile is illustrative, not an HMRC example, and rests on these assumptions.
According to HMRC (Residence and FIG Regime Manual, 2025), at most 60 days in a tax year can be ignored for exceptional circumstances such as a sudden serious illness or civil unrest, if you intend to leave as soon as possible. It is “a limit, not an allowance or entitlement”.

Begin Your Journey With UsThe test gives one status for a whole tax year. When you start to live or work abroad, or come to the UK, the year can be split into a UK part and an overseas part. In HMRC's words, “The individual does not have a choice whether split year treatment applies.”
There are eight cases, three for a departure (Cases 1 to 3) and five for an arrival (Cases 4 to 8). Case 1 (starting full-time work overseas) requires, among other conditions, UK residence that year and the previous one, then non-residence the following year through the full-time overseas work test. Case 3 requires, among other conditions, that you cease to have any UK home, then spend fewer than 16 days in the UK and establish a link with the new country within 6 months. Case 1 takes priority over Cases 2 and 3, and Case 2 over Case 3.
You get no split-year treatment if you live abroad for less than a full tax year before returning. The split is reported on form SA109. Where both countries tax the same income in such a year, HMRC describes credit relief, the country of residence crediting the tax paid on UK income: one form of relief when two countries tax the same year.
Under Finance Act 2013, Schedule 45, you are temporarily non-resident if you had sole UK residence in at least 4 of the 7 tax years before departure and your absence lasts “5 years or less”. To fall outside the rule, HMRC says, the absence must run to “5 years plus one day”.
“From 6 April 2025 it is no longer possible to use the remittance basis of taxation”, and the 4-year foreign income and gains (FIG) regime replaced it on the same date.
The conditions are narrow (HMRC, Residence and FIG Regime Manual, updated April 2026):
Relief covers foreign dividends, interest, overseas property income and foreign gains, claimed year by year in the Self Assessment return: by 31 January 2028 for 2025 to 2026, with no discretion for a late claim. Relieved amounts can be brought to the UK without a further charge.
A claim costs you, for that tax year, the personal allowance (£12,570 for 2026 to 2027), the Capital Gains Tax annual exempt amount and the foreign capital losses of the year. They are lost “regardless of whether a claim or election is made for only foreign income, only foreign gains, or only OWR”.
| Regime | Who | What | Limit or cost |
|---|---|---|---|
| 4-year FIG regime | New resident after 10 tax years away | Foreign income and gains | 4 tax years; allowances lost |
| Overseas Workday Relief (OWR) | Employee who is a qualifying new resident | Earnings for duties outside the UK | Lower of 30% of qualifying employment income or £300,000 a year (HMRC, updated 6 April 2026) |
| Temporary Repatriation Facility (TRF) | UK resident who used the remittance basis in an earlier year | Overseas capital designated in the return | 12% charge for 2025 to 2026 or 2026 to 2027, 15% for 2027 to 2028 (Finance Act 2025, Schedule 10) |
OWR is elected in the return and needs no offshore account for income of periods from 6 April 2025; earlier income taxable on remittance must still be kept offshore. The TRF charge is “a charge on capital”: no credit for foreign tax, and outside a treaty that covers only income and gains. All three regimes need UK residence under the test.
For inheritance tax, the domicile rules were also replaced from 6 April 2025 by long-term UK resident rules, a status that can continue for a time after departure.
The 4-year foreign income and gains regime replaced the remittance basis on 6 April 2025. Its conditions are narrow, and a claim costs allowances for the tax year in which it is made.
| Profile | The rules that matter | The first question they ask |
|---|---|---|
| Leaver abroad who keeps a home, family or visits in the UK | Leaver's column, five ties, deemed days, split-year Cases 1 to 3, five-year rule | How many ties remain this tax year? |
| Arriver, or returner after a long absence | Arriver's column, four ties, split-year Cases 4 to 8, 4-year regime | Were the 10 previous tax years all non-UK? |
| Returner within five years | Temporary non-residence | What was realised during the absence? |
| Former remittance basis user now UK resident | Temporary Repatriation Facility | Is there qualifying overseas capital to designate? |
HMRC expects records that support each statement:
One rule outlasts departure: “You usually have to pay tax on your UK income even if you're not a UK resident.” The test is applied year by year, on the facts of each case, and day counts, ties and regimes rarely move one at a time.

Each tax year, 6 April to 5 April, is tested separately.
The more UK ties you have, the fewer days you can spend in the UK. The UK counts its own midnights over its own tax year, whatever the other country's test says, and your ties are read afresh each tax year. Contact us for more information.
Only if you meet one of eight cases: the treatment is applied, never chosen. None applies if you return before a full tax year abroad.
Possibly, if you had sole UK residence in at least 4 of the 7 tax years before leaving. The year of return can then tax:
The test measures residence, through days and ties, and has applied since 6 April 2013. What changed on 6 April 2025 is the taxation of foreign income, which no longer depends on domicile.
