UK Tax Residency When You Leave: The Statutory Test

How the Statutory Residence Test works

The SRT is a structured set of tests applied in order. First, the automatic overseas tests: if any apply, the person is non-resident for the tax year regardless of other factors. Second, the automatic UK tests: if any apply, the person is resident. Third, the sufficient ties test: if neither automatic test applies, the number of UK ties combined with UK days determines residence.

The test applies to each UK tax year separately (6 April to 5 April). Days are counted by midnight presence; a person present in the UK at midnight on a given day is counted as a UK day for that date.

The automatic overseas tests

Three automatic overseas tests: less than 16 days in the UK in the tax year for someone resident in any of the previous three years; less than 46 days for someone not resident in any of the previous three years; full-time work overseas with limited UK days and workdays.

If any test applies, the person is non-resident for the tax year. The first two tests are common for early or late departures during the year. The third test (full-time overseas work) is the standard route for workers moving abroad mid-year.

The automatic UK tests

Three automatic UK tests: 183 days or more in the UK; only home in the UK (no overseas home, or any overseas home not used substantially); full-time work in the UK with limited overseas time.

If any test applies and no automatic overseas test applies, the person is UK resident. The 183-day test is the simplest; reaching 183 days is virtually impossible to avoid for someone with substantial UK presence.

The sufficient ties test

Where neither automatic test applies, the sufficient ties test combines UK days with the number of qualifying ties: family tie (UK-resident spouse or minor children), accommodation tie (UK home available for at least 91 days), work tie (working 40+ days in the UK), 90-day tie (90+ days in the UK in either of the previous two years), and country tie (UK as the country of most days).

The number of ties needed for residence varies by UK days and whether the person was UK resident in any of the previous three years. The full table is in Finance Act 2013 Schedule 45 Part 1; specialist tax software typically handles the calculation.

Split-year treatment

Split-year treatment under Part 3 of Schedule 45 treats the year as two parts: a UK part (resident) and an overseas part (non-resident). It applies in defined Cases 1-8: leaving the UK for full-time work overseas, partner accompanying a worker abroad, ceasing to have a UK home, arriving in the UK for full-time work, and others.

Each Case has specific conditions on the timing, the type of move, and the existence of corresponding conditions in the other country. The Case that applies determines the split date. HMRC's guidance manual covers the conditions in detail.

Documenting the position

The applicant should document UK days throughout the year: dates of arrival and departure for every UK trip. Boarding passes, hotel receipts, mobile phone location records and similar evidence support the day count.

Ties evidence: for the family tie, evidence of spouse and children's residence; for the accommodation tie, evidence of when the home was available; for the work tie, employer records and travel patterns.

Practical implications for departures

Most departures aim to achieve non-resident status from a specific date, often the date of moving abroad. Split-year treatment Case 1 (full-time work overseas) or Case 3 (ceasing to have a UK home) is the common route.

The year-of-departure tax return reports UK-source income for the resident part and provides for split-year if claimed. Non-residents continue to be taxable on UK-source income (rental, employment in the UK if any, UK pensions) after the split.

The structure of the Statutory Residence Test

Part 1 of Schedule 45 FA 2013: the automatic overseas tests. Three tests; meeting any one makes the person non-UK resident for the tax year regardless of other factors. The automatic overseas tests provide certainty: meeting the test means non-resident; not meeting moves the analysis to the next stage.

Part 1 also includes the automatic UK tests: 183 days in the UK, only home in the UK, full-time work in the UK. Meeting any one makes the person UK resident.

Part 1 sufficient ties test: where neither automatic test applies. The number of UK days combines with the number of UK ties (family, accommodation, work, 90-day, country) to determine residence. The thresholds vary by previous-year residence status.

Part 3: split-year treatment. Where the year is treated as part UK and part overseas. Eight specific Cases (1-8) cover the situations where split-year applies, each with its own conditions.

Schedule 45 covers other related rules: temporary non-residence (Part 4), and various definitions and special cases.

Counting UK days: midnight rule and exceptions

Midnight presence test: a day counts as a UK day if the person is present in the UK at midnight at the end of that day. This is the standard test.

Exceptional circumstances: some days do not count even if midnight presence applies. Examples: travel cancelled by exceptional circumstances beyond the person's control, certain medical emergencies, certain death of a family member. The exceptions are narrow.

Departure days and arrival days: each day with any time in the UK counts (unless an exception applies). Travelling Monday afternoon to Wednesday morning is 3 UK days under the midnight rule because Monday, Tuesday and Wednesday all see midnight presence.

Transit through UK airports: present at midnight at a UK airport counts as a UK day even if the person did not pass through immigration. Pre-clearance flights are an exception in narrow circumstances.

Half days: not relevant. The test is binary at midnight. The total UK days for the tax year is the count of midnight-presence days.

The five UK ties test in detail

Family tie: spouse, civil partner, partner with cohabitation, or minor child resident in the UK. The other person's residence in the UK creates the family tie.

Accommodation tie: a UK home available for at least 91 consecutive days. The test is availability, not use. Owning a UK property without occupying it can still create an accommodation tie.

Work tie: working 40 or more days in the UK in the tax year. A 'workday' is a day on which more than 3 hours of work is performed; the threshold is per day.

90-day tie: spending 90 or more days in the UK in either of the previous two tax years. The previous-year days are counted in the current tax year's tie calculation.

Country tie: spending more midnights in the UK than in any other single country. Where the person divides time between several countries, the country with the most UK midnights creates the tie.

Combining ties with UK days: the table in Part 1 of Schedule 45 specifies the residence outcome by number of ties and number of UK days. The thresholds differ for those resident in any of the previous three tax years (lower threshold) versus those not previously resident (higher threshold).

Split-year treatment in detail

Case 1: leaving the UK for full-time overseas work. Specific conditions on the work and the timing. The split date is when the overseas work starts.

Case 2: partner accompanying or joining a partner who has left for overseas work. The split applies if the partner moved abroad and the person joins them.

Case 3: ceasing to have a UK home. The split date is when the UK home is given up. Subsequent occupation of UK accommodation is restricted.

Cases 4-8: arriving in the UK (4: full-time work in the UK, 5: ceasing full-time work overseas, 6: partner of UK-arriving worker, 7: starting to have a UK home, 8: starting to have a UK accommodation tie).

The order of testing: when multiple Cases might apply, the rules specify which one governs. The Home Office's RDR3 manual covers the priority order in detail.

Practical case studies and common patterns

Mid-year departure for overseas work: Case 1 split-year. The departure date is the split date if the conditions are met (full-time overseas work, sufficient overseas workdays, limited UK days post-departure). UK income up to the split date is taxed; post-departure overseas-source income is not UK taxable.

Mid-year departure for non-work reasons: Case 3 if the UK home is given up. If the family is the connecting factor, Case 2 may apply.

Mid-year arrival to start UK work: Case 4 split-year. UK tax applies from the arrival or work-start date; pre-arrival overseas income is not UK-taxable.

Returning to the UK after years abroad: standard SRT applies in the year of return. Where the person has been abroad for the qualifying period, the temporary non-residence rules typically do not apply.

Cross-border tax planning for the year of departure

Statutory Residence Test (SRT): determines UK tax residence on a year-by-year basis. The automatic overseas tests, automatic UK tests, and sufficient ties tests in Schedule 45 FA 2013 give the framework.

Split-year treatment: applies to the year of departure or arrival where conditions are met. Cases 1-8 cover the specific scenarios; the year is treated as part UK (resident) and part overseas (non-resident).

Double Taxation Treaty: bilateral agreement between the UK and the country of residence allocates taxing rights and provides relief. Most DTTs use the credit method; the UK or country of residence taxes with credit for tax paid in the other.

Non-resident UK tax: continues on UK-source income (rental, pensions, property gains) after departure. UK dividends and interest are typically subject to disregarded income rules with no UK tax for non-residents.

Temporary non-residence: gains realised during absence of less than 5 complete tax years can be brought back into UK tax on return. Planning the absence period and the timing of gains is part of cross-border tax strategy.

Long-term planning across the immigration journey

Long-term planning across the visa lifecycle: the journey from initial visa to ILR to British citizenship spans 6-8 years typically. Building the documentary record, maintaining lawful status, planning extensions and switches, and the eventual settlement application all benefit from a long-term view.

Career and family planning around immigration: visa requirements interact with career progression, education choices, family timing, and other life decisions. Where significant life events are planned, considering the immigration position is part of the planning.

Risk management: keep documents, maintain contact with UKVI through changes of address, comply with visa conditions, build a clean record. Issues that arise during the visa years are easier to address proactively than at the settlement application.

Backup routes: where the primary route encounters difficulties, alternative routes provide options. Skilled Worker holders can consider Global Talent, family route, Innovator Founder depending on circumstances. Long Residence (10 years) provides a backup settlement path.

Future return scenarios: where the applicant may return to the country of origin or move elsewhere, planning preserves options. Maintaining country-of-origin ties, financial records, and qualifications supports future flexibility.

Frequently asked questions

How do I know if I am UK tax resident?

Apply the Statutory Residence Test for the tax year. Automatic overseas tests first; automatic UK tests second; sufficient ties test third. UK tax software handles the calculation. The HMRC manual RDR3 covers the test in detail.

What is split-year treatment?

A treatment under Part 3 of Schedule 45 Finance Act 2013 that splits the tax year into a UK part (resident) and an overseas part (non-resident) where defined Cases 1-8 apply. Common in the year of departure or arrival.

How many days can I be in the UK before becoming tax resident?

Depends on the SRT. The 183-day automatic UK test is the upper bound; below this, the sufficient ties test combines UK days with qualifying ties. Without ties, up to 182 days are permitted; with multiple ties, the threshold can be much lower.

Does leaving the UK make me non-resident automatically?

No. Becoming non-resident depends on meeting the SRT for the tax year. Mid-year departures often achieve non-resident status through split-year treatment if the conditions are met; without split-year, residence is judged on the whole tax year.

Do I need to tell HMRC when I leave the UK?

Yes. Form P85 notifies HMRC of departure. The year-of-departure self-assessment tax return covers the UK-source income for the resident part and claims split-year if applicable. HMRC updates the records based on the form and return.
