Overview

• New CEBR modelling projects that if 25% of non-dom residents leave, the UK will lose £4.6 billion in tax revenue over five years and shed about 3,200 private-sector jobs.
• The Treasury is exploring watering down inheritance tax on trusts, a concession advisers say could stem departures among wealthy foreign residents.
• Companies House data show more than 4,400 company directors left the UK in the past year, with departures up 75% in April year-on-year.
• The Office for Budget Responsibility’s earlier 12–25% departure estimate has been coupled with Treasury warnings that high-earners’ behavioural responses pose an uncertain fiscal risk.
• Opponents argue that reports of a mass wealth exodus are overstated, noting Henley & Partners and New World Wealth data account for just 0.3% of the UK’s millionaire population.
