## Defining UK Tax Residency: The Statutory Residence Test (SRT)
The UK uses the Statutory Residence Test to decide how tax residence is determined. Key factors include:
- **Automated days spent in the UK**: fewer than 16 days yields automatic non-residence (if resident previous year), 90 days for those not resident previous year.
- **Connections test**: family ties, accommodation, work pattern, etc.
For digital nomads, carefully managing days can help you avoid becoming UK resident unintentionally. Track diaries and travel dates precisely.
## IR35 / Off-Payroll Working: Key Lessons
Even if you are outside the UK, contracts with UK firms may still subject you to IR35 (off-payroll worker rules):
- If working via your own company or intermediary for UK clients, check whether IR35 applies—this influences whether you’re treated similarly to an employee for tax and National Insurance.
- If you are inside IR35, you may need to pay tax and NIC as though you are an employee (after expenses), even if contract says otherwise.
## Planning Opportunities & Risk Mitigation
- **Dual domicile or split-year treatment**: Under SRT, if both UK entry and exit meets certain criteria, you may have split tax years; only part of earnings fall under UK tax.
- **Use of Double Taxation Agreements (DTAs)**: If you earn abroad and pay foreign tax, DTAs can avoid you being taxed twice.
- **Maximise tax reliefs**: E.g. personal allowance, global income exclusions, foreign tax credits. Always ensure you meet necessary criteria.
## Case Study: Remote Developer from Spain
> _Carlos, a software developer, lives in Spain but completes three 3-week contracts in UK per year. He spends around 70 days in UK annually. Under SRT, he’d likely be classified UK resident (90-day test), making him liable on global income. He arranges for split-year treatment: in the year of moving to Spain, he claims non-residence. On IR35, he also ensures that his contract terms pass UK CEST or court tests to avoid falling inside IR35._
## Actions You Should Take Now
- Keep a **migration diary**: record entry, exit, location of work, accommodation.
- Review contracts with UK firms: ensure clarity on control, substitution and supervision—key IR35 indicators.
- Seek specialist advice before claiming split year or non-residency—mistakes can be costly.
- Understand social security obligations abroad: sometimes those apply even if UK tax is avoided.
## Emerging Risks & Policy Watchpoints
- HMRC has closed off some reliefs and informal arrangements (e.g. remittance basis no longer available after 6 April 2025 for many). Be sure you understand recent rule changes.
- Proposed changes to how employees claim employment expenses may alter your eligibility for reliefs if you ask your employer to reimburse or if costs are borne by you.
By staying ahead with documentation, reviewing your contracts, and tracking your presence and income carefully, you can enjoy the nomadic lifestyle without undue tax risks.
