Britain faces exodus of billionaires amid wealth tax fears

Britain has seen more billionaires leave its shores than any other country over the past two years, sparking concerns that additional departures could follow if a wealth tax is introduced. Recent analysis by New World Wealth reveals that 18 dollar-billionaires, representing a quarter of the UK’s ultra-wealthy individuals, moved their tax residency abroad between 2023 and 2024. This is the highest exodus globally, with countries like China and Russia trailing behind with 12 and 8 departures respectively.

The property tycoon Asif Aziz, who owns the Trocadero leisure complex in London, shifted his tax residency to Abu Dhabi last year, citing changes to Britain’s tax rules. Similarly, the Egyptian billionaire and Aston Villa co-owner Nassef Sawiris relocated to Italy after moving his family investment group to Abu Dhabi. Sawiris attributed his move to dissatisfaction with the UK’s economic policies and the abolition of non-domiciled (non-dom) tax status. This sentiment was echoed by property magnates Ian and Richard Livingstone, who left for Monaco following similar changes in tax regulations.

The October 2024 budget, presented by Chancellor Rachel Reeves, scrapped the non-dom tax perk, moving to a residence-based system. The changes also introduced British inheritance tax on the global assets of foreign residents who have lived in the UK for over a decade. Labour is now considering a wealth tax to address fiscal shortfalls, but this has fuelled fears of accelerating the exodus of high-net-worth individuals.

Maxwell Marlow from the Adam Smith Institute noted that “wealthy individuals vote with their feet” and criticised the UK’s economic climate for driving capital out of the country. He argued that policies mimicking Italy’s or the US’s high-net-worth visa systems could attract wealth creators back and revitalise Britain’s financial climate. New World Wealth confirmed the UK’s economy and stagnant stock market have struggled to encourage new wealth since the 2008 financial crisis, further pushing the ultra-wealthy to relocate.

The research highlighted that the UAE has been a key beneficiary of the exodus, with a 28 billionaire count, marking the largest proportional increase. The United States witnessed the highest overall growth, adding 15 billionaires during the same period, reinforcing its attractiveness as a hub for the wealthy. Meanwhile, Britain’s ranking deteriorated, with the number of billionaires dropping from 165 in 2022 to just 72 by the end of 2024, as measured by New World Wealth’s stricter metrics.

Critics argue that fears of wealthy individuals leaving the UK may be overstated. The Tax Justice Network champions a 2 per cent wealth tax on assets exceeding £10 million and believes the narrative around billionaires fleeing is exaggerated. However, proponents of maintaining the current tax framework warn that continuous departures could undermine Britain’s economic base and deter entrepreneurs from investing in the country’s future.

As rival financial hubs like Dubai, Frankfurt, and Milan continue their ascent at London’s expense, persuading the super-rich to remain in Britain becomes increasingly vital to its economic stability. Policymakers are under pressure to balance public demand for equitable taxation with maintaining the UK’s appeal as a destination for global wealth and enterprise.
