UK Statutory Residence Test: Are You UK Tax Resident?

Am I UK tax resident? The short answer

Your UK residence status is decided by the Statutory Residence Test, a set of rules introduced by Finance Act 2013 that replaced decades of case law with a defined sequence. It is applied in a fixed order, and the first stage that produces an answer is the answer — you never move on to a later stage once an earlier one has resolved.

If you spend 183 days or more in the UK in a tax year, you are UK resident and nothing else matters. If you spend fewer than 16 days here and were resident in any of the previous three tax years, you are non-resident and nothing else matters. Between those two extremes, the outcome depends on how many days you spend here, whether you worked full-time in the UK or overseas, and how many connections — "ties" — you retain.

How the Statutory Residence Test works

The test runs in three stages, and understanding the order matters as much as understanding the content.

Stage one is the automatic overseas tests. Meeting any one of these makes you non-resident outright. Nothing in stages two or three can override it.

Stage two is the automatic UK tests. These only apply if you failed every automatic overseas test. Meeting any one makes you resident.

Stage three is the sufficient ties test. This only applies if no automatic test resolved your position. Here your day count is read against the number of UK ties you hold, with the threshold sliding as days increase.

The UK tax year runs from 6 April to 5 April, which is not the calendar year used by most other jurisdictions. If you are also being assessed somewhere that uses a calendar year, the two counts cover different periods and cannot be compared directly.

Stage one: the automatic overseas tests

There are three routes to automatic non-residence.

The first applies if you were UK resident in one or more of the previous three tax years and spend fewer than 16 days in the UK. The second applies if you were not resident in any of those three years and spend fewer than 46 days here. The third applies if you work full-time overseas across the year, spend fewer than 91 days in the UK, and work more than three hours in the UK on fewer than 31 days.

That third test is the one most often relied upon by people who have genuinely relocated for work, and it is also the one most often lost. The full-time overseas requirement means averaging 35 hours a week with no significant break of 31 days or more, and the workday limits are strict. A handful of extra UK meetings can cost you the test entirely.

Stage two: the automatic UK tests

If no overseas test applied, three tests can make you automatically resident.

Spending 183 days or more in the UK is decisive on its own. Having your only home in the UK for a period of at least 91 consecutive days, being present in it on at least 30 days, and having no overseas home you spend meaningful time in, also makes you resident. So does working full-time in the UK across any 365-day period, where more than 75% of your workdays are UK workdays.

The "only home" test catches people who sell or let their overseas property while keeping a UK base, often without realising the two facts interact.

Stage three: the sufficient ties test

If neither set of automatic tests resolved your position, residence turns on ties. There are five: a family tie, an accommodation tie, a work tie, a 90-day tie, and a country tie.

The number of ties needed to make you resident falls as your day count rises — and it differs depending on your recent history.

Arrivers and leavers: the difference that catches people out

An arriver was not UK resident in any of the three previous tax years. A leaver was resident in at least one of them.

As the table shows, leavers face a lower threshold at every band. Someone who left the UK last year and returns for 130 days becomes UK resident on a single tie — a UK home they can access, or a spouse still living here, would be enough. An arriver spending exactly the same 130 days would need two.

The country tie compounds this. It applies only to leavers, and it is met where the UK is the country you spent most days in. Recently departed expatriates therefore have an extra tie available to catch them precisely when they are most likely to be spending significant time back in the UK.

This asymmetry is the single most common source of error in self-assessed residence positions, and it works in the direction people least expect: the year after you leave is usually more dangerous than the year you left.

What counts as a day in the UK?

A day counts if you are in the UK at midnight at the end of it. Arrival and departure days therefore behave differently from how most people assume — fly out at 9pm and that day does not count; fly out at 1am the following morning and it does.

Two exceptions matter. Transit passengers who arrive and depart the next day without engaging in activities substantially unrelated to their journey can disregard the day. Days you are prevented from leaving by exceptional circumstances beyond your control can also be disregarded, capped at 60 days in a tax year. HMRC interprets "exceptional" narrowly.

Separately, the deeming rule can add days back. If you have at least three UK ties, were UK resident in one of the previous three years, and have more than 30 qualifying days in the UK, days beyond that thirtieth can count even without a midnight presence.

What UK residence means for your tax

If you are UK resident, you are generally taxable on worldwide income and gains: overseas pension income, foreign rental income, and investment returns wherever they arise. Double tax treaty relief may reduce the overlap where another country also taxes the same income, but it usually has to be claimed rather than applied automatically.

If you are non-resident, you are generally taxable only on UK-source income — UK employment income, UK rental income, and in most cases UK pension income. Non-residents may not be eligible for full UK pension tax relief on contributions.

Residence also interacts with inheritance tax, though it no longer determines it directly. Since 6 April 2025 the UK has used a residence-based IHT system: once you have been UK resident for 10 of the previous 20 tax years, your worldwide estate falls within the UK IHT net, and remains there for a period after you cease to be resident.

Split-year treatment and temporary non-residence

Two rules commonly modify the headline result.

Split-year treatment divides the tax year into a UK part and an overseas part where you arrive or leave part-way through. Eight statutory cases govern it, and it applies automatically where one is met rather than being something you elect into.

Temporary non-residence claws back tax on certain income and gains if you return to the UK within roughly five years of leaving. Dividends from close companies, pension lump sums and some capital gains realised during a short absence can be taxed in the year of return. Anyone planning a short-term departure to realise a gain should take advice first — this rule exists specifically to counter that.

Compliance caveat

The Statutory Residence Test contains definitions, exceptions and anti-avoidance provisions well beyond what any interactive tool can capture. The burden of proof sits with you, not with HMRC, and day counts are the most frequently challenged element of any residence position. Keep contemporaneous records of travel dates, workdays, and accommodation — boarding passes, calendars and tenancy agreements — from the outset. Reconstructing them years later is far weaker evidence.

How Global Investments can help

Residence status determines which country taxes your pension, your investments and eventually your estate, and most of the levers that change it can only be pulled prospectively. Our advisers work with clients across more than 60 countries to review residence positions before they crystallise, model the effect of a planned relocation, and coordinate with tax specialists in both jurisdictions where two countries have a competing claim.
