The United Kingdom is set to abolish its long‑standing non‑domiciled (“non‑dom”) tax regime, a change that will affect high‑net‑worth individuals who have relied on the ability to keep foreign income and gains largely untaxed while residing in the UK.
What the non‑dom regime was
- Origins: Introduced in 1799 to protect colonial investments.
- Mechanism: Non‑doms who were UK tax residents paid UK tax only on UK‑source income and on foreign income remitted (brought) into the UK.
- Benefit: Foreign dividends (e.g., from Singapore) and capital gains could be held abroad tax‑free as long as they were not remitted.
Changes coming into force
- Effective date: 6 April 2025 (the start of the UK tax year).
- Abolition of the remittance basis: The current remittance‑based taxation for UK‑resident non‑doms will end.
- New 4‑year “foreign income and gains” (FIG) regime:
- Applies to individuals who become UK tax residents after at least 10 years of non‑residence.
- For the first four tax years of UK residence, foreign income and gains are not taxed in the UK, provided the individual did not reside in the UK during the preceding decade.
- During this period, foreign income can be remitted to the UK without additional UK tax.
- Transition relief: A one‑year reduction in the amount of foreign income subject to tax for those moving from the remittance basis, intended to encourage the transfer of overseas wealth into the UK.
- 12 % tax on remitted FIG: For tax years 2025‑26 and 2026‑27, any foreign income and gains that are remitted will be taxed at a flat 12 % rate.
- Inheritance tax: Remains residence‑based; changes to the non‑dom regime could affect the calculation of UK inheritance tax liabilities for non‑resident assets.
How the new system compares with other jurisdictions
| Country | Main tax‑friendly scheme | Key features | Typical cost / requirement |
|---|---|---|---|
| Italy | 15‑year “lump‑sum” flat tax | €100 000 annual tax on worldwide income for new residents; pathway to citizenship after 10 years | €100 k/year |
| Greece | 15‑year residency program | €100 k annual tax on worldwide income; property investment required | €100 k/year + property |
| Ireland | Non‑dom regime (still active) | Similar remittance basis; easier immigration via Common Travel Area for UK citizens | No fixed tax, depends on remittances |
| Malta | Non‑dom / residency | Low flat tax on foreign income; favorable trust regime | Variable, often €15 k‑30 k |
| Cyprus | Non‑dom regime | 17 % tax on foreign dividends, no tax on foreign capital gains | No fixed annual fee |
| Switzerland | Lump‑sum taxation (varies by canton) | Fixed annual tax based on living expenses; possible route to citizenship | CHF 30 k‑100 k+ |
| Monaco | No personal income tax | Residency requires substantial financial means and accommodation | €500 k+ assets, accommodation |
| Georgia | 1 %–10 % flat tax rates | Simple tax code, low corporate tax | Low thresholds |
| Serbia | Low personal tax rates | Flat 10 % personal income tax | No minimum investment |
Practical considerations for potential UK movers
- Eligibility for the 4‑year FIG regime – Must have been non‑resident for at least the previous ten tax years. Those who have lived in the UK more recently will be subject to the standard UK residence tax on worldwide income.
- Tax rate comparison – Even with the 12 % flat rate on remitted income, the UK rate can be higher than the effective rates in Italy, Greece, or Malta for comparable high‑income earners.
- Wealth‑creation vs. wealth‑preservation – The UK system taxes UK‑source income and gains regardless of domicile; foreign‑source income will be taxed only when remitted (subject to the 12 % rate during the transition).
- Inheritance tax exposure – Since UK inheritance tax is residence‑based, moving to the UK could increase exposure to the 40 % rate on worldwide assets, unless proper planning (e.g., trusts) is implemented.
- Immigration pathways – The UK does not currently offer a direct “golden visa” tied to investment; residency generally requires work, study, family ties, or EU Settlement Scheme eligibility. Irish citizens can still move freely under the Common Travel Area.
- Professional advice – Coordinating immigration, tax, and asset‑protection advice is essential, as separate specialists may produce conflicting plans.
Decision criteria
- Length of prior non‑residence – Determines eligibility for the favorable 4‑year FIG period.
- Source of income – High reliance on foreign dividends or capital gains may be less attractive under the new UK rules.
- Desired citizenship timeline – The UK offers naturalisation after 5‑6 years of residence, but the path is more restrictive than some EU programs that grant citizenship after 10‑15 years of tax‑resident status.
- Lifestyle preferences – Climate, language, and cultural factors may outweigh marginal tax savings.
- Asset protection needs – Trust structures (e.g., Cook Islands, Bahamas) remain useful, but UK tax treatment of distributions from non‑resident trusts will apply.
Summary
From April 2025 the UK will end its historic non‑dom tax regime, replacing it with a limited‑duration foreign‑income exemption for newcomers who have been abroad for a decade. While the new system offers a short‑term tax shelter, the 12 % remittance tax and broader residence‑based taxation diminish the UK’s appeal to ultra‑high‑net‑worth individuals. Alternative European programs—Italy’s €100 k flat tax, Greece’s 15‑year residency scheme, Ireland’s still‑active non‑dom rules, and Malta or Cyprus non‑dom structures—provide more predictable long‑term tax environments. Prospective movers should assess residency history, income sources, and inheritance exposure, and seek integrated immigration‑tax planning before deciding whether the UK remains a viable base for their wealth.
