This article is for general information only and should not be considered financial or tax advice. Tax treatment depends on individual circumstances. Always seek professional advice before making decisions.
Understanding UK Tax Residency
Why Residency Status Matters
UK residents are generally taxed on worldwide income, while non residents are typically taxed only on UK sourced income.

- Rental income from UK property
- Employment linked to UK duties

Statutory Residence Test Explained
The Statutory Residence Test determines your tax status based on time spent in the UK and your connections.
Residency Threshold

| 91 to 120 | Likely resident |
| 121 to 182 | Resident |
