UK Expat Tax & Statutory Residence Test (SRT) Complete Guide 2026
Comprehensive 2026 guide to UK expat tax residence: SRT Automatic Overseas and UK tests, sufficient ties, day counting, split-year treatment, temporary non-residence, the new 4-year Foreign Income and Gains regime, Double Taxation Relief and SA109 reporting.
Executive Summary: Core UK Expat Tax Principles
UK personal tax residence is determined separately for each tax year under the Statutory Residence Test (SRT), which considers time spent in the UK, work performed in the UK, and the individual's UK connections. Residence is only the first part of the analysis: the actual UK tax charge then depends on the type of income or gains, statutory exemptions/reliefs, treaty rules and, for qualifying new UK residents, the 4-year Foreign Income and Gains (FIG) regime.
Expat Tax Status Comparison: Resident vs Non-Resident
The table below contrasts tax treatment between UK residents and non-residents:
| Tax Area | UK Tax Resident | Non-UK Tax Resident |
|---|---|---|
| Foreign income | Generally within UK tax on the arising basis, subject to relief such as the FIG regime | Generally outside UK tax, subject to specific UK-source and statutory rules |
| Foreign capital gains | Generally taxable in the UK, subject to available relief | Generally outside UK CGT, subject to UK land/property rules and the temporary non-residence provisions |
| UK rental income | Generally taxable in the UK | Generally taxable in the UK; Non-Resident Landlord Scheme withholding can apply to rental payments |
| UK property / land gains | Potentially taxable under ordinary UK CGT rules | Generally within UK CGT/NRCGT rules for relevant UK property or land disposals |
| Foreign income of qualifying new resident | Potentially exempt if a valid FIG claim is made for qualifying foreign income/gains | Outside UK tax as a non-resident, subject to the ordinary non-resident and source rules |
The 5-Year Temporary Non-Residence Rule
The statutory temporary non-residence rules can apply when an individual returns to the UK after a period of temporary non-residence. Broadly, the person must have had sole UK residence in a relevant residence period before departure, have had sole UK residence (or a qualifying split-year residence period) in at least 4 of the 7 tax years immediately before the year of departure, and have a period of non-residence of 5 years or less. If the rules apply, certain specified income and gains received during the temporary non-residence can be brought into charge in the year of return. It is not a rule that automatically taxes every capital gain made abroad.
Step-by-Step HMRC Compliance Action Plan
When leaving the UK, determine your SRT position and whether split-year treatment applies. Keep a detailed UK day-count and work-day record, retain evidence such as travel records and employment information, use P85 where appropriate, and complete SA109 as part of Self Assessment where a return is required. If you later become UK resident again, also review the temporary non-residence and FIG-regime rules.
Current 2026 SRT Decision Sequence
The SRT is applied separately for each tax year. Start with the number of UK days. If you were in the UK for 183 days or more, you are UK resident and do not need to consider the other tests. If you were below 183 days, consider the Automatic Overseas Tests. If none applies, consider the Automatic UK Tests. If those are inconclusive, apply the Sufficient Ties Test.
Automatic Overseas Test 1 — Fewer Than 16 Days
You are automatically non-UK resident if you were UK resident in one or more of the 3 tax years before the current year and spend fewer than 16 days in the UK in the current tax year.
Automatic Overseas Test 2 — Fewer Than 46 Days
You are automatically non-UK resident if you were not UK resident in any of the 3 tax years before the current year and spend fewer than 46 days in the UK in the current tax year.
Automatic Overseas Test 3 — Full-Time Work Overseas
The third Automatic Overseas Test applies where you work full-time overseas for the relevant tax year, meet the sufficient-hours overseas test, have no significant break from overseas work, spend fewer than 91 days in the UK, and have fewer than 31 UK work days. A UK work day is generally a day on which you perform more than 3 hours of work in the UK.
The 90-Day Tie — Not a 90-Day 'Tie-Breaker'
The 90-day tie is one of the statutory UK ties used by the Sufficient Ties Test. You generally have a 90-day tie if you spent more than 90 days in the UK in either of the 2 tax years immediately before the tax year being tested. It does not by itself make you resident and should not be described as a treaty-style tie-breaker.
The Five UK Ties
The Sufficient Ties Test uses a maximum of five UK ties depending on whether the person was resident in the previous 3 tax years. The ties are the family tie, accommodation tie, work tie, 90-day tie and, for leavers, the country tie. The more ties a person has, the fewer UK days they can spend before becoming resident.
| Tie | Core Concept |
|---|---|
| Family tie | Close family connections in the UK under the statutory definition |
| Accommodation tie | Accessible accommodation in the UK meeting the statutory conditions |
| Work tie | Sufficient UK work days |
| 90-day tie | More than 90 UK days in either of the previous 2 tax years |
| Country tie | The UK is the country in which the person spends the greatest number of days, relevant to leavers |
Sufficient Ties — Leaver Thresholds
If you were UK resident in one or more of the previous 3 tax years, the number of ties needed depends on your UK-day count. Under the current guidance, 16–45 UK days requires at least 4 ties, 46–90 days requires at least 3 ties, 91–120 days requires at least 2 ties, and more than 120 days requires at least 1 tie.
| UK Days | Ties Needed for UK Residence |
|---|---|
| 16–45 | At least 4 |
| 46–90 | At least 3 |
| 91–120 | At least 2 |
| Over 120 | At least 1 |
Sufficient Ties — Arriver Thresholds
If you were not UK resident in any of the previous 3 tax years, the sufficient-ties threshold is different: 46–90 UK days requires all 4 applicable ties, 91–120 days requires at least 3 ties, and more than 120 days requires at least 2 ties.
| UK Days | Ties Needed for UK Residence |
|---|---|
| 16–45 | Does not trigger residence under this table |
| 46–90 | All 4 applicable ties |
| 91–120 | At least 3 |
| Over 120 | At least 2 |
UK Day Counting — Midnight Rule
For the SRT, a day spent in the UK normally counts when you are present in the UK at midnight at the end of that day. There are specific exceptions and special rules for transit days, exceptional circumstances and deemed days. A travel log should therefore record arrival/departure details as well as where you were at midnight.
Exceptional Circumstances
Certain days can be disregarded from the UK day count when presence in the UK is caused by exceptional circumstances beyond the individual's control or foresight, subject to the statutory conditions and 60-day overall limit. HMRC expects the circumstances to be exceptional; ordinary travel disruption, personal convenience or foreseeable events do not automatically qualify.
The Deeming Rule
The SRT contains a deeming rule that can add UK days for certain people who have accumulated enough actual UK days and whose previous-day pattern satisfies the statutory conditions. This is separate from the normal midnight rule and can matter to frequent visitors who repeatedly stay in the UK.
Automatic UK Test 1 — 183 Days
If you spend 183 days or more in the UK during the tax year, you are automatically UK resident. No further SRT test is necessary once this threshold is met.
Automatic UK Test 2 — UK Home Test
The second Automatic UK Test can apply where you have a home in the UK and the statutory 91-day/30-day conditions are satisfied, including the required treatment of overseas homes. This is more detailed than simply saying 'you have a home in the UK for 91 days'.
Automatic UK Test 3 — Full-Time Work in the UK
The third Automatic UK Test can make an individual UK resident where they work full-time in the UK for a 365-day period, more than 75% of the relevant work days are UK work days, and at least one such UK work day falls in the tax year being considered. It is a detailed annual-work test and should not be reduced to a simple UK employment contract.
Split-Year Treatment
Split-year treatment can divide a UK tax year into a UK part and an overseas part when the statutory conditions of one of the split-year cases are satisfied. There are cases covering, among other things, starting full-time work overseas, accompanying a partner who starts full-time work overseas, ceasing to have a UK home, starting a UK home, starting full-time work in the UK and ceasing full-time work overseas. Split-year treatment affects how residence is applied during the year; it does not simply mean that the year is arbitrarily divided on the moving date.
4-Year Foreign Income and Gains (FIG) Regime
From 6 April 2025, the FIG regime replaced the remittance basis for new qualifying residents. A qualifying new resident is generally someone in their first 4 tax years of UK residence following at least 10 consecutive tax years of non-UK residence. A valid claim can exempt qualifying foreign income and gains arising during the claim year, but the relief is not automatic and certain allowances are lost for a year in which a claim is made.
FIG Regime Does Not Automatically Cover Foreign Employment Income
Foreign employment income is subject to separate rules. A qualifying new resident may be able to claim Overseas Workday Relief for the qualifying portion of foreign employment income attributable to non-UK workdays, subject to the conditions of that relief. The FIG regime itself should therefore not be described as automatically exempting all foreign salary.
FIG Claim Can Cost Personal Allowances
A FIG claim is not simply a free exemption with no trade-off. For a claim year, the claimant generally loses the Income Tax personal allowance and Capital Gains Tax annual exempt amount, and can lose other allowances such as Married Couple's Allowance, Marriage Allowance and Blind Person's Allowance where otherwise available. The foreign income/gains claim can also affect adjusted net income calculations.
Temporary Non-Residence — 4 of 7 + 5 Years or Less
For the current statutory rules, temporary non-residence can apply where the individual had sole UK residence in a qualifying residence period, had sole UK residence or a qualifying split-year residence period in at least 4 of the 7 tax years immediately before departure, and the period of non-residence is 5 years or less. If the rules apply, specified categories of income and gains can be taxed in the year of return.
| Condition | Current Requirement |
|---|---|
| Previous UK residence | At least 4 of the 7 tax years immediately before departure satisfy the statutory residence condition |
| Non-residence duration | 5 years or less |
| Return | Individual becomes UK resident again |
| Effect | Specified income/gains during temporary non-residence can be brought into charge |
Temporary Non-Residence Is Not Only About Capital Gains
The current temporary non-residence rules cover specified categories of income and gains, including certain capital gains, flexible drawdown pension withdrawals, certain employer-financed retirement benefits, chargeable event gains, offshore income gains and certain remitted foreign income. The correct analysis therefore depends on the exact type of amount received during the temporary non-residence period.
Double Taxation Relief for UK Expats
Being UK non-resident does not remove foreign-country taxation, and being UK resident does not necessarily mean paying tax twice without relief. Where the same income is taxed by both countries, Double Taxation Relief can be available under a treaty or UK unilateral-relief rules, subject to the relevant conditions and limits. Treaty residence, source-country taxing rights and the type of income must all be analysed separately.
Non-Resident UK Rental Income & the Non-Resident Landlord Scheme
UK rental income can remain taxable when you live abroad. Under the Non-Resident Landlord Scheme, letting agents and certain tenants can be required to deduct tax from rental payments unless HMRC has authorised the landlord to receive rent gross. The landlord may also need to file Self Assessment and report rental profit. The withholding rate should not be confused with the individual's final UK tax liability.
Non-Resident UK Property Gains & 60-Day Reporting
Non-residents can be within UK Capital Gains Tax rules for relevant disposals of UK land and property. Where a 60-day reporting requirement applies, the CGT return and payment deadline is normally 60 days from completion. The exact requirement depends on the disposal and taxpayer's circumstances, so the page should not state that every UK property disposal is identical.
P85 — When to Use It
P85 is used to tell HMRC that you have left or are leaving the UK and may claim a PAYE repayment. It is especially relevant where the person leaves UK employment and is going abroad for at least a full tax year. However, someone who is required to submit Self Assessment for the departure year generally reports the residence position through the return instead, subject to specific situations where P85 remains appropriate.
SA109 — Reporting Residence Correctly
SA109 is the residence supplementary page accompanying Self Assessment. It is used to report UK residence status, split-year treatment and related residence information. It is not a 'claim for non-residence' in the sense that completing the form creates the status. The tax position must be calculated under Schedule 45 Finance Act 2013 and HMRC's SRT guidance, with SA109 documenting the taxpayer's position.
2026 Practical Expat Residence Workflow
For each tax year, first count UK days and determine whether 183 days or more were spent in the UK. If not, test Automatic Overseas 1–3. If none applies, test Automatic UK 1–3. If those tests are inconclusive, calculate the relevant UK ties and apply the sufficient-ties table for a leaver or arriver. Then check split-year treatment, treaty residence, temporary non-residence, FIG eligibility, foreign tax credit relief and the required HMRC forms.
