The UK abolished its non-domiciled tax regime in April 2025, ending a 200-year-old system that allowed foreign residents to avoid UK tax on overseas income. Industry voices predicted a wealth exodus. HMRC data tells a different story.
Non-dom status permitted UK residents whose permanent home was abroad to pay UK tax only on income brought into the country. The regime attracted an estimated 68,000 individuals in 2023, contributing £8.9 billion in income tax and national insurance. Labour's 2024 manifesto pledged abolition, citing fairness. The Conservative government had already announced phase-out plans before the election. From April 2025, all UK residents face worldwide taxation after four years of residence, with a transitional relief window for existing non-doms.

HMRC figures released in August 2025 showed non-dom registrations fell 6% in the year preceding abolition—from approximately 68,000 in 2023 to 64,000 in 2024. The Tax Justice Network analysed the data and found no evidence of the predicted mass departure. Wealth advisors had forecast departures of 20-30%, citing Switzerland, Dubai, and Italy as destinations. The Financial Times reported that actual movement remained within historical variance.
For individuals with £5 million in offshore assets, the old regime allowed zero UK tax on foreign dividends if funds stayed abroad. Under the new residence-based system, four years of UK residence triggers worldwide taxation at 20-45% on income, plus inheritance tax on global estates. Transitional relief permits 50% exemption on foreign income for two tax years (2025/26 and 2026/27) for those who were non-doms before April 2025, tapering to zero by 2027/28.
Practical obstacles include the four-year cliff—residents must leave before year four to avoid worldwide tax exposure. Redomiciliation to jurisdictions like Monaco or Switzerland requires genuine residence, not mailbox arrangements. HMRC's Statutory Residence Test counts UK days strictly: 183+ days equals tax residence, with tie-breaker rules for 120-182 days. Trusts established before April 2025 retain some protections, but new settlements face immediate UK taxation. Legal fees for restructuring average £50,000-150,000, according to KPMG guidance published in January 2026.

France
France positioned itself as a non-dom alternative through its existing impatriate regime, offering partial tax exemption on foreign income for new residents. Le Monde reported in July 2025 that France saw the UK abolition as a recruitment opportunity for financial professionals and entrepreneurs. The impatriate regime exempts 30% of salary and 50% of certain foreign income for eight years, available to executives and specialists relocating to France.

For a UK-based fund manager earning £500,000 with £2 million in offshore investment income, French impatriate status would exempt £150,000 of salary and £1 million of foreign income from French tax. The effective rate on exempted amounts is zero; remaining income faces French progressive rates up to 45%, plus 17.2% social charges on earned income. Wealth tax (IFI) applies to French real estate above €1.3 million but excludes foreign assets, unlike the UK's worldwide inheritance tax.
Qualification requires a role in France that did not exist in the prior five years, genuine relocation, and employer sponsorship. The regime does not cover passive investors or retirees. Processing takes 3-6 months through the French tax authority. Housing costs in Paris exceed London for equivalent properties—€8,000-15,000 monthly for family accommodation in central arrondissements. French employment law mandates 35-hour work weeks and extensive employee protections, complicating founder equity structures.

The UK's shift to residence-based taxation aligns it with most OECD countries but removes a competitive edge in attracting mobile wealth. Whether the £8.9 billion tax contribution from non-doms will be replaced by revenue from those who stay, or lost to jurisdictions with territorial or lump-sum regimes, remains an open question. The 6% pre-abolition decline suggests some movement, but far below the scale predicted by advisory firms with commercial interests in relocation services. For individuals weighing options, the calculation hinges on asset location, income sources, and willingness to establish genuine residence elsewhere—not merely tax residence on paper.
