UK Statutory Residence Test: The Complete Guide (2026)

What is the Statutory Residence Test?

The Statutory Residence Test (SRT) is the official method used by HMRC to determine whether you are UK tax resident for a given tax year (6 April to 5 April). It was introduced in April 2013, replacing the previous - and much vaguer - set of rules that left many taxpayers in limbo.

The SRT is defined in Schedule 45 of the Finance Act 2013 and explained in HMRC's guidance document RDR3. It applies to all individuals, regardless of nationality or domicile. Getting your residence status right matters: UK residents pay UK tax on worldwide income and gains, while non-residents generally only pay UK tax on UK-sourced income.

Why the SRT Was Introduced

Before April 2013, UK tax residence was determined by a patchwork of HMRC practice, case law, and guidance that had evolved over decades. The rules were unclear enough that HMRC itself acknowledged a "need for greater certainty." The SRT replaced all of that with a single, statutory framework - one that applies the same way to everyone, every year, regardless of circumstance.

The practical effect is that you can now work out your residence status yourself, step by step, using the same rules HMRC uses. That said, for complex situations - multiple countries, part-year moves, overseas employment - professional advice is often warranted.

How Days Are Counted

Before walking through the tests, it's important to understand how HMRC counts days. A day counts as a UK day if you are present in the UK at midnight at the end of that day. This is sometimes called the "midnight rule."

Transit days - where you arrive and leave the UK on the same calendar day without being present at midnight - do not count under the midnight rule. However, if you are in the UK at midnight on any night, that counts as one UK day regardless of how briefly you were present.

There is an important exception: if you are present in the UK at midnight but only because of exceptional circumstances beyond your control (for example, a medical emergency or volcanic ash cloud), those days may be disregarded - up to a maximum of 60 days per year.

The Three Stages

The SRT works in three stages, applied in order. Once a test gives a definitive answer, the remaining tests are skipped. You only reach Stage 3 if neither Stage 1 nor Stage 2 gives a conclusive result.

Stage 1: Automatic Overseas Tests

The automatic overseas tests (AOTs) are checked first. If you meet any one of them, you are non-resident for the year - no further tests needed.

First Automatic Overseas Test

You were not UK resident in any of the previous 3 tax years and you spend fewer than 46 days in the UK in the current tax year.

This is the simplest test for new arrivals from abroad or for people who have been non-resident for several years. If you have no recent UK residence history and visit only briefly, you fall clearly outside UK residence.

Second Automatic Overseas Test

You were UK resident in one or more of the previous 3 tax years and you spend fewer than 16 days in the UK in the current year.

This is the relevant test for people who have recently left the UK. The 16-day threshold is deliberately strict: HMRC wants to ensure that recent UK residents who keep close connections to the UK do not avoid residence simply by spending slightly less time here. For a full guide to the year of departure and subsequent years, see leaving the UK mid-year: what happens to your tax residency.

Third Automatic Overseas Test (Full-Time Work Overseas)

You work full-time overseas throughout the tax year, you spend fewer than 91 days in the UK, and you spend fewer than 31 days working in the UK.

"Full-time" for this purpose means working an average of at least 35 hours per week overseas, with no significant gaps (gaps of more than 31 consecutive days, or gaps totalling more than 90 days in the year, disqualify you). Only days where you actually work 3 or more hours count as overseas working days for this purpose. See the third automatic overseas test guide for the full sufficient hours calculation and worked example.

---

Stage 2: Automatic UK Tests

If none of the AOTs apply, the automatic UK tests (AUTs) are checked next. Meeting any one of them makes you UK resident automatically.

First Automatic UK Test (183-Day Rule)

You spend 183 or more days in the UK in the tax year. Read more about how the 183-day rule actually works - including what it doesn't mean.

This is the most widely known rule. If you are present in the UK at midnight for at least 183 nights in the tax year, you are UK resident. There is no way around it - no ties, no circumstances, no exceptions can override this result (other than the exceptional circumstances provision on day counting).

Second Automatic UK Test (Only Home in the UK)

You have a home in the UK during the tax year, and one of the following applies:

• You have no overseas home, or
• You have an overseas home but spend fewer than 30 days in it during the tax year

For this test, a "home" must be somewhere you actually use as a home - not a property you purely own as an investment. The UK home must also be available to you for a continuous period of at least 91 days, and you must spend at least 30 separate days in it.

This test catches people who nominally relocate abroad but maintain a UK home they use regularly while spending little time in their overseas property.

Third Automatic UK Test (Full-Time Work in the UK)

You work full-time in the UK for any period of 365 consecutive days, all or part of which falls within the tax year.

As with the full-time overseas test, "full-time" means an average of at least 35 hours per week, with no significant gaps. Working days are days where you work 3 or more hours in the UK.

Stage 3: The Sufficient Ties Test

If neither Stage 1 nor Stage 2 gives a conclusive result, you move to the sufficient ties test. This is where residency becomes nuanced - and where the distinction between leavers and arrivers becomes critical. For a full breakdown of each tie, see the UK ties test explained.

What Are Ties?

Ties are connections to the UK. There are five types:

1. Family tie: Your spouse, civil partner, or a child under 18 is UK resident during the tax year. Note that if you are separated from your spouse, the family tie from a spouse does not apply. Children you see in the UK on fewer than 61 days also do not create a family tie.

2. Accommodation tie: You have a place to stay in the UK that is available to you for a continuous period of at least 91 days, and you actually spend at least one night there during the tax year. For a close relative's home (parent, grandparent, sibling, or adult child), the threshold is 16 nights rather than one.

3. Work tie: You work in the UK on at least 40 days in the tax year (where "work" means 3 or more hours on a given day).

4. 90-day tie: You spent more than 90 days in the UK in either or both of the previous two tax years.

5. Country tie (leavers only): You spend more days in the UK in the tax year than in any other single country. This tie is only available against leavers - not against arrivers.

Leavers vs Arrivers

This is one of the most important distinctions in the entire SRT.

A leaver is someone who was UK resident in at least one of the previous 3 tax years. A leaver can have up to 5 ties (including the country tie) counted against them.

An arriver is someone who was not UK resident in any of the previous 3 tax years. An arriver can have at most 4 ties (the country tie is unavailable to arrivers).

The practical difference is significant: leavers face a tougher test. HMRC assumes that recent UK residents have stronger connections to the UK, and so applies higher scrutiny.

Sufficient Ties Thresholds

Your residence status under the sufficient ties test depends on how many days you spent in the UK and how many ties you have.

For leavers:

Days in UK	Resident if you have…
16–45	4 or more ties
46–90	3 or more ties
91–120	2 or more ties
121–182	1 or more ties

For arrivers:

Days in UK	Resident if you have…
46–90	All 4 ties
91–120	3 or more ties
121–182	2 or more ties

If your day count falls below the lowest band in the relevant table, you are non-resident regardless of ties. If your day count reaches 183, the first Automatic UK Test already applies and you never reach Stage 3. See how many days you can spend in the UK for a full breakdown of both tables with worked examples.

Split-Year Treatment

If you move to or from the UK part way through a tax year, the entire year is still assessed under the SRT. However, if you are UK resident for that year and meet certain conditions, the year may be split into a UK part (taxed as a UK resident) and an overseas part (taxed as a non-resident).

Split-year treatment is set out in Part 3 of Schedule 45. There are 8 defined cases - 3 for people leaving the UK, and 5 for people arriving. The cases cover situations such as:

• Starting full-time work overseas partway through the year
• A spouse or civil partner joining a partner who is already working overseas
• Ceasing to have a home in the UK
• Returning from full-time overseas work
• Starting to have a home in the UK only

If the conditions of a case are met, split-year treatment applies automatically - the individual has no discretion over whether it applies (RFIG21010). It is particularly important for income like dividends, rental income, or capital gains that arise in the overseas part of the year, which may be sheltered from UK tax. See the full split year treatment guide for the conditions of each case with worked examples.

Who Needs to Work Through the SRT?

You need to consider the SRT carefully if you:

• Spend time in both the UK and overseas during a tax year
• Are moving to or from the UK part-way through a year
• Work across borders, whether employed or self-employed
• Have family, property, or business interests in the UK while living abroad

If you spend the entire tax year in the UK with no overseas ties, you are almost certainly UK resident. If you have been abroad for years with minimal UK contact, you are almost certainly non-resident. The SRT matters most - and is most worth working through carefully - for anyone in the grey area between those two extremes.

When to Seek Professional Advice

The SRT is a legal test, and getting it wrong can lead to underpayment or overpayment of tax, along with penalties and interest. While the framework is designed to be objective, several situations warrant professional advice:

• You are a leaver with 2 or 3 ties and borderline day counts
• Your overseas work situation is complex or irregular
• You are claiming split-year treatment for the first time
• You have income or gains in multiple jurisdictions
• You are affected by a double tax treaty (treaty residence may differ from SRT residence)

The SRT determines UK domestic law residence. Tax treaties between the UK and other countries can override this for treaty purposes - an additional layer of complexity that is beyond the scope of the SRT itself.
