Early payroll data compiled by HM Revenue & Customs indicates that the abolition of the UK’s non-domiciled tax status has not triggered the mass departure of wealthy residents that some advisers had predicted. Officials briefed on the findings said departures so far are in line with, and in some cases below, Office for Budget Responsibility projections that one in four non-doms with offshore trusts would leave the country. Provisional figures show 60,700 non-doms in the 2023-24 tax year, about 30 percent fewer than a decade earlier. The data offers political cover to Chancellor Rachel Reeves, whose 2024 Budget extended inheritance-tax liabilities to worldwide assets held in offshore trusts. The Treasury expects the wider non-dom overhaul to raise roughly £4 billion in 2026-27 and almost £6 billion the following year, helping to close a fiscal gap that independent economists put at more than £20 billion. Reeves is also examining ways to tighten inheritance-tax rules for UK residents, including capping lifetime gifts that can be made free of tax and revisiting the ‘seven-year rule’ that currently exempts older gifts. Wealth managers warn the changes could erode longstanding planning opportunities, while Conservative critics accuse Labour of targeting “prudent and family-minded” households. The Chancellor is expected to wait for fuller HMRC evidence before deciding whether to adjust the inheritance-tax proposals in her autumn Budget.
