💡 Costs this calculator doesn't include
- Private health insurance — you lose free NHS access as a non-resident (beyond emergency care). Cover commonly runs £2,000–£20,000+/year depending on age, family size, and pre-existing conditions.
- International school fees if you have children — typically £10,000–£30,000+ per child per year in popular exile destinations, plus one-off enrolment fees.
- Life, income protection, or critical illness insurance taken out while UK-resident, which may be repriced or refused once you become a non-resident.
- The recurring cost of flights and accommodation to visit family in the UK — easy to underweight against the headline tax saving.
- Voluntary National Insurance contributions (Class 2/3) to protect your State Pension entitlement while abroad.
Visiting the UK is also rationed: the SRT ties test means every extra day in the UK reduces your safety margin against becoming UK tax resident again — as few as 45 days/year if you retain UK ties.
⚖️ Important: This is a simplified estimate, not tax advice
UK non-residence is determined by the Statutory Residence Test (SRT), which counts UK presence days and examines family/accommodation/work ties. Becoming non-resident typically requires spending fewer than 16 days in the UK (or 46 if no UK home). The 183-day test still applies — spending ≥183 days automatically makes you UK resident.
UK Inheritance Tax exposure may continue for up to 10 years after leaving, under new rules effective April 2025 for long-term UK residents (10 of the previous 20 tax years). Always seek professional tax advice before making any decision to emigrate for tax purposes.
Frequently asked questions
How do I become non-resident for UK tax purposes?
UK tax residence is determined by the Statutory Residence Test (SRT). Automatic non-residence applies if you spent fewer than 16 days in the UK in the tax year (for those who were UK resident in one or more of the preceding 3 years). If you have no UK home and fewer than 46 days in the UK, you are also automatically non-resident. Between 16 and 182 days, residence depends on the number of UK "ties" you have — including family ties, accommodation ties, work ties, and the 90-day tie. Spending 183 or more days in the UK in a tax year always makes you UK resident.
What happens to my UK income tax when I leave?
Once you are non-UK resident, you only pay UK income tax on UK-source income — such as UK employment income, UK rental income, UK dividends, and UK pensions. Income earned from employment wholly performed overseas is not taxable in the UK. On a £120,000 income, the current UK tax burden is approximately £41,843 (income tax + NI), versus an estimated £0 in the UAE, saving £41,843 annually.
Do I still pay UK Capital Gains Tax (CGT) as a non-resident?
Non-residents are exempt from UK CGT on most assets. However, UK residential property gains remain subject to UK CGT even after you leave — you must report disposals within 60 days. Commercial property and direct/indirect interests in UK property-rich companies also remain in scope. UK stocks, shares, and non-property investments held abroad are generally CGT-free once you are non-resident, as long as you do not return to the UK within 5 tax years (the temporary non-residence rules).
What is the UK Inheritance Tax exposure after leaving?
From April 2025, the UK moved to a new long-term resident (LTR) IHT regime. If you were resident in the UK for 10 or more of the previous 20 tax years, you become a "long-term resident" and your worldwide assets remain within the scope of UK IHT. After leaving, you remain subject to UK IHT for a tail period — up to 10 years for someone who was resident for 20+ years. Non-residents who were not long-term residents are only subject to IHT on UK-sited assets (including UK property).
What are the most popular tax exile destinations for UK citizens?
The most popular destinations include: the UAE (0% income tax and CGT), Monaco (0% income tax, very high cost of living), Portugal (IFICI successor to NHR — 20% flat for 10 years), Switzerland (lump-sum taxation based on expenses), Singapore (territorial tax, no CGT), Gibraltar (Category 2 residence, tax capped at ~£30k/yr), and the Channel Islands (20% flat, no CGT). The best choice depends on your income type, desired lifestyle, visa accessibility, and willingness to permanently relocate.
