The UK statutory residency test determines whether an individual is treated as a UK tax resident for a given tax year (April 1 – April 5). For many who plan to relocate abroad, the crucial step is to become non‑resident in the UK, which often matters more than acquiring residency elsewhere.
Automatic offshore (non‑resident) tests
If any of the following conditions is met, the person is automatically non‑resident for the tax year, regardless of other ties:
| Test | Conditions |
|---|---|
| 1. Recent UK resident, few days in UK | • Resident in the UK for at least one of the three tax years preceding the current year and • Spend fewer than 16 days in the UK during the current tax year. |
| 2. No recent UK residence, very few days in UK | • Not resident in the UK for any of the three tax years preceding the current year and • Spend fewer than 46 days in the UK during the current tax year. |
| 3. Full‑time overseas work | • Work full‑time abroad for the whole tax year (including periods of annual, sick or parental leave). • Spend fewer than 91 days in the UK during the tax year. • Work more than three hours in the UK on fewer than 31 days. • No “significant break” in overseas work (a break of ≥ 31 consecutive days without ≥ 3 hours of overseas work). • Applies to both employees and the self‑employed; excludes volunteers and crew on board vehicles, aircraft, or ships. |
Meeting any of these tests means the individual is automatically treated as a non‑resident, allowing them to limit UK tax liability even if they maintain other connections abroad.
Automatic residency tests
If none of the offshore tests apply, the UK checks whether the individual is automatically a resident:
| Test | Conditions |
|---|---|
| 1. 183‑day rule | Spend 183 days or more in the UK during the tax year. |
| 2. Home‑based test | • Have a home in the UK for at least 91 consecutive days (including at least 30 days within the tax year). • Be present in that home for at least 30 days in the tax year. • Have no overseas home, or if an overseas home exists, be present there for fewer than 30 days in the tax year. • The test needs to be satisfied for one UK home only; each property is assessed separately. |
| 3. Full‑time UK work test | • Work full‑time in the UK for a continuous 365‑day period that overlaps the tax year. • During that period, ≥ 75 % of the days on which you work more than three hours are UK workdays. • At least one of those days falls within the tax year. |
If any of these residency tests are satisfied, the person is automatically a UK resident for that tax year.
Sufficient‑ties test
When neither the automatic offshore nor the automatic residency tests apply, the UK applies a “sufficient ties” analysis. The ties considered are:
- Family ties – spouse, civil partner, or minor children resident in the UK.
- Accommodation ties – availability of a place to live in the UK for a continuous period of at least 91 days, with at least 30 days of actual presence.
- Work ties – employment in the UK (including self‑employment) for at least 40 days in the tax year.
- 90‑day tie – presence in the UK for 90 days or more in the tax year.
The number of ties required to be deemed resident depends on the total days spent in the UK:
| Days in UK | Required ties to be resident |
|---|---|
| 0‑15 | 0 (automatically non‑resident) |
| 16‑45 | 4 ties |
| 46‑90 | 3 ties |
| 91‑120 | 2 ties |
| 121‑150 | 1 tie |
| 151‑182 | 0 ties (automatically resident) |
If the individual’s presence and ties do not meet the threshold, they remain non‑resident.
Practical steps for becoming UK non‑resident
- Track days carefully – Count every day spent in the UK, including travel days, to ensure thresholds are not unintentionally exceeded.
- Plan work location – Full‑time overseas employment is the most flexible route; it allows up to 90 days in the UK (with limited work days) while preserving non‑resident status.
- Manage UK accommodation – If you own or rent a UK property, consider either relinquishing the lease or limiting occupancy to avoid triggering the home‑based test.
- Monitor family ties – Relocating spouses or children can create family ties that increase the risk of residency.
- Document overseas work – Keep records of work hours, locations, and any leave taken to prove continuous overseas employment if the full‑time overseas test is used.
By aligning personal circumstances with the automatic offshore criteria or, failing that, limiting ties and days spent in the UK, individuals can effectively sever UK tax residency while they establish residence elsewhere.
