What Healey put on the table
UK Chancellor John Healey delivered his first budget on Wednesday, shortly after the International Monetary Fund praised Britain's fiscal discipline. The package includes preferential tax treatment for certain founder stake sales beginning next year, while offering few fresh measures for ultra-wealthy individuals from overseas despite ideas being explored this year.
Budget documents show HMRC tightening its approach as part of modernization efforts. Investors and business owners with UK footprints and at least £200 billion combined are being brought under closer scrutiny.
Where the tax crosshairs are moving
State-backed overseas investment firms that have been exempt from UK tax on rental income are now targeted for a 15% levy. The measure would extend to holdings such as portions of Regent Street as well as the Canary Wharf banking district, widening the UK's scrutiny of overseas investors' property income.
The government also said it will proceed with a foreign tax credit to reduce punitive tax rates for UK residents who earn income from US entities. That change is scheduled to take effect in 2028, the year before the next general election.
HMRC said it spent the summer identifying 200 billionaires with UK tax exposure even if they do not live in the country. Each now has a dedicated customer compliance manager, and officials characterized their impact on the UK economy as "substantial." Instead of offering perks, HMRC invited them to a "voluntary discussion" regarding their finances.

How this fits the broader reset of UK wealth policy
These moves extend a wider reset under Labour, now led by Prime Minister Andy Burnham, following tax changes introduced under his predecessor in April 2025 that dented the UK's long-standing wealth-hub status. At the prior budget, when Rachel Reeves was chancellor and Keir Starmer prime minister, the government moved to curb the impact of reforms first proposed by the Conservatives in early 2024.
The reshuffle in rules coincided with a steady outflow of billionaires. Some shut down firms and listed luxury homes for sale as they moved abroad. Departures include Nassef Sawiris, Egypt's second-richest person, alongside Swiss tech billionaire Guillaume Pousaz.
Some British billionaires are leaving too. Hedge fund founder Chris Rokos is relocating to Greece, which introduced a preferential tax regime for wealthy foreigners nearly a decade ago that draws on the UK's now-defunct non-dom system. Last year, Richard Desmond shifted his tax residence to the United Arab Emirates and subsequently restructured his wealth to ramp up investment outside the UK.
Investor takeaways
The run-up to the budget sparked months of stake-sale planning among UK entrepreneurs worried about higher capital-gains taxes. "There were discussions about potentially realizing gains," said Piers Master, a partner at Charles Russell Speechlys in London, adding many clients were "convinced" capital-gains taxes could be aligned with income tax rates of up to 45%. Healey's founder-friendly treatment starts next year, but deals already in progress are likely to miss out.
Non-domiciled taxpayers have been paying more than £9 billion ($12 billion) a year in taxes, according to HMRC, with 2024 and 2025 provisional. The old non-dom system let wealthy foreigners avoid UK tax on offshore wealth for up to 15 years after reforms nearly a decade ago ended permanent status. The replacement is typically simpler but lasts four years, a period many affluent families view as too short to settle.
Market sentiment captured the opportunity cost. Iain Tait, who heads the private investment office at W1M, said, "In the deeply volatile world that we live in at the moment, we could have the UK looking like a beacon of stability." He added, "And we're missing that opportunity." The bottom line: watch the timing on founder stake relief, the targeted 15% levy on state-backed foreign landlords with exposure to marquee London districts, the 2028 foreign tax credit for US income, and HMRC's tougher posture toward the £200 billion cohort.
