Key Points
Chris Rokos, Britain's third-highest taxpayer, is relocating to Greece to pay €100,000 annually instead of £330m.
Greece's 15-year high-net-worth regime requires €500,000 investment and offers flat tax on overseas income.
Rokos's exit signals broader exodus of billionaires citing UK tax policy changes and non-dom regime abolition.
Tax experts say certainty and immigration reform matter more than competing on rates alone.
Billionaire hedge fund founder Chris Rokos is leaving the UK for Greece, marking a significant loss of tax revenue for Britain. Rokos, ranked third in the Sunday Times list of top UK taxpayers, paid £330m to the Treasury last year but will now pay just €100,000 annually on overseas income under Greece’s high-net-worth investor regime. His departure reflects growing concern among the ultra-wealthy about UK tax policy amid Chancellor John Healey’s upcoming budget.
Why Rokos is moving and what Greece offers
Greece introduced a flat tax regime in 2019 allowing foreign high-net-worth individuals to pay €100,000 per year on all overseas income for 15 years. In exchange, they must invest at least €500,000 in Greek real estate, businesses, or shares within three years. Rokos, founder of Rokos Capital Management with approximately $4bn net worth, will open an office in Athens as part of the move.
The £330m revenue question for Britain
Dan Neidle, founder of think tank Tax Policy Associates, told the BBC that losing Rokos’s £330m annual tax contribution is “quite a lot of money.” He noted it could fund 4,500 teachers and exceeds the revenue from entire UK taxes. However, Neidle acknowledged the Treasury has “no good statistics” on the true scale of revenue loss from wealthy departures, describing the issue as largely anecdotal.
Broader exodus amid non-dom changes
Rokos joins other high-profile exits including steel billionaire Lakshmi Mittal. Labour’s tax policies, including closing non-dom tax loopholes and raising stamp duty for non-UK residents, have prompted wealthy individuals to seek alternatives. Italy has also become attractive, offering €100,000 annual fees on overseas earnings. Shadow Chancellor Andrew Griffith called Rokos’s departure “bad news for all of us,” arguing it reduces opportunities for young people and increases tax burden on others.
What experts say the UK should do
Neidle argues the government must provide certainty rather than compete on tax rates alone. He cited four changes to non-dom rules in three years and rumours of a wealth tax as destabilising factors. He also suggested phasing in inheritance tax gradually for new arrivals and reforming immigration law to allow wealthy individuals to bring their families. The government spokesperson countered that the UK remains “an attractive destination” with “a competitive and stable tax system.”
Final Thoughts
Rokos’s exit exposes a real gap in Britain’s tax competitiveness for billionaires, but the underlying issue runs deeper than rates alone. Certainty, immigration policy, and broader perceptions of UK stability matter as much as the numbers on a tax bill.
