Blow to Chancellor's tax take as 1,800 non-doms quit the UK

""The Treasury is effectively flying blind about the behaviour of the most responsive group of non-doms,""

""The wealthiest are investors rather than salaried workers, so they do not always appear in HMRC's datasets. The tax-revenue implications of their departures are significant.""

""If you make your home in Britain, you should pay your taxes here. That is why we abolished the non-dom tax status - to invest in our public services, including the NHS.""

Chamberlain Walker estimates around 1,800 non-domiciled individuals—50% more than the Treasury forecast—have left the UK since the non-dom status was abolished in April 2025. The reform aimed to raise £34 billion over five years by replacing the fixed annual charge with a new regime. Many of those departing are high-earning investors who often do not appear in HMRC datasets and who contribute substantial income and capital gains tax. The consultancy warns these departures could materially reduce projected revenues. The Treasury dismissed the figures as anecdotal and defended the abolition as ensuring residents pay taxes for public services, including the NHS.
