UK Tax Residency: The Statutory Residence Test, Explained (2026/27)
The UK's Statutory Residence Test (SRT) is the legal decision tree that decides whether you are a UK tax resident for a given tax year, which runs from 6 April to the following 5 April. It works through three stages in strict order: the automatic overseas tests, the automatic UK tests, and finally the "sufficient ties" test, which weighs your UK connections against days spent here. If you arrive in or leave the UK partway through the year, "split year" treatment can limit your resident period to part of the year.
Stage 1: the automatic overseas tests
If you meet any one of these four tests, you are automatically non-resident — no further questions asked:
- The 16-day test: you were UK resident in any of the previous 3 tax years, and you spend fewer than 16 days in the UK this year.
- The 46-day test: you were not UK resident in any of the previous 3 tax years, and you spend fewer than 46 days in the UK this year.
- Full-time work abroad: you work full-time overseas, spend fewer than 91 days in the UK, and work more than 3 hours in the UK on fewer than 31 days.
- Death: you die during the tax year (special rules apply).
Stage 2: the automatic UK tests
If none of the overseas tests apply, you are automatically resident if you meet any one of these:
- The 183-day test: you spend 183 days or more in the UK during the tax year.
- The home test: you have a home in the UK, are present there for at least 30 days in the tax year, and either have no overseas home or are present at your overseas home for fewer than 30 days.
- Full-time work in the UK: you work full-time in the UK with no significant break, more than 75% of your workdays are UK workdays, and at least one day is a UK workday.
- Death: you die during the tax year (special rules apply).
The home test catches many newcomers by surprise: renting a flat in London where you spend 40 nights, while keeping a family home abroad you visit for only 20 nights, makes you automatically UK resident even with well under 183 days.
Stage 3: the sufficient ties test
If neither set of automatic tests is conclusive, your UK "ties" are counted and compared against your days in the UK. The five ties are:
- Family tie: your spouse, civil partner, or minor children are UK resident.
- Accommodation tie: you have a UK place to live available for 91+ consecutive days (even a parent's spare room can count), and you spend at least one night there.
- Work tie: you do more than 3 hours of work in the UK on more than 3 days in the tax year.
- 90-day tie: you spent more than 90 days in the UK in either of the previous 2 tax years.
- Country tie: you are present in the UK at midnight more than in any other single country (leavers only — people resident in any of the previous 3 years).
Then compare your tie count to your days:
| Days in the UK | Leaver (resident in any of previous 3 years) | Arriver (not resident in previous 3 years) |
|---|---|---|
| Under 16 | Always non-resident | Always non-resident |
| 16–45 | Resident if 4+ ties | Resident if 4+ ties |
| 46–90 | Resident if 3+ ties | Resident if 3+ ties |
| 91–120 | Resident if 2+ ties | Resident if 2+ ties |
| Over 120 | Resident if 1+ tie | Always resident |
Example: a newcomer (arriver) who spends 100 days in the UK with 1 tie is non-resident; with 2 ties, resident. A leaver spending 130 days with even a single tie is resident.
How days are counted
A day counts if you are in the UK at midnight at the end of it. Days in transit do not count if you arrive as a passenger and leave the next day without unrelated activities. Up to 60 days can be excluded for exceptional circumstances beyond your control — sudden illness, natural disaster, or a travel ban — but not routine delays.
Split year treatment
If you become resident or cease to be resident mid-year, the tax year can be split into a UK part and an overseas part, so you are taxed as a resident only for the relevant period. There are 8 statutory cases — 3 for arrivals (only home in the UK; full-time work in the UK; ceasing full-time work abroad) and 5 for departures. You generally must claim split year treatment on your Self Assessment return — it is not always automatic.
What residency actually means for your wallet
UK tax residents are taxed on their worldwide income and gains. A major change took effect on 6 April 2025: the old remittance basis for non-domiciled individuals was abolished and replaced by the 4-year Foreign Income and Gains (FIG) regime. If you become UK tax resident after at least 10 consecutive tax years of non-residence, you can claim relief from UK tax on your foreign income and gains for your first 4 years of residence (you give up the Personal Allowance and the Capital Gains annual exempt amount in claim years). Non-residents are generally taxed only on UK-source income.
Practical tips for newcomers
- Track your days from day one — keep flight records and a simple spreadsheet; a late-night arrival counts under the midnight rule.
- Mind the home test — a 12-month UK lease with rare visits to a retained overseas home can trigger automatic residence.
- Check split year eligibility before filing — it can save tax on pre-arrival foreign income.
- Register with HMRC promptly once you start work or a business; residency and filing obligations are separate questions.
Frequently asked questions
I spent exactly 183 days in the UK. Am I resident?
Yes — the automatic UK test is "183 days or more." Day 183 makes you automatically resident, regardless of ties.
I moved to the UK in October. Am I resident for the whole tax year?
Not necessarily. If you meet one of the split-year cases (for example, starting to have your only home in the UK), the year splits and you are treated as resident only from your arrival. Otherwise the SRT makes you resident for the full year.
Can I be tax resident in two countries at once?
Yes, under domestic law. The UK-France or UK-US tax treaty (for example) then applies tie-breaker rules to decide which country gets primary taxing rights — but you may still need to file in both.
Do full-time students get special treatment?
No — students take the same SRT as everyone else. Time in the UK as a student counts fully toward the day-count and ties tests.
