Eight hundred wealthy residents left France last year, taking roughly 4 billion euros with them. The reason isn’t just politics; it’s four decades of France repeatedly trying, and struggling, to tax its richest citizens
France lost a net total of 800 millionaires in 2025, a small fraction of its overall wealthy population but a trend drawing serious attention from economists and policymakers alike, according to a media report citing the Henley & Partners Wealth Migration Report. France still counts 2.4 million people with a net worth above 1 million euros, according to the UBS Global Wealth Report, so this outflow represents only a sliver of that population. But each departure carries real financial weight. Every departing millionaire took with them an average of 5 million euros in personal assets last year, adding up to roughly 4 billion euros leaving the country in total, according to the French think tank iFRAP.
Economists warn that even a relatively small number of departures can matter disproportionately, since wealthy individuals often own businesses, fund investment and generate substantial tax revenue that ordinary earners simply cannot replace.
Why they’re actually leaving
There is no single explanation for the exodus. Political instability has played a real role; France has cycled through six prime ministers in the past five years, alongside repeated budget crises and lingering uncertainty over how the government plans to tackle its growing debt burden. The prospect of Marine Le Pen winning the April 2027 presidential election has added another layer of unease. While her National Rally party has tried to reassure businesses and investors, economists have questioned whether its spending plans can be squared with France’s already strained public finances and European Union fiscal rules.
The other major driver has been an ongoing national and international campaign to tax the ultra-wealthy more heavily, a debate that has now run through several distinct phases over the past year.
The Zucman tax fight
The most recent battle centred on a proposal from French economist Gabriel Zucman, calling for a 2 per cent annual tax on fortunes exceeding 100 million euros. The plan also included an exit tax, designed specifically to prevent the kind of capital flight that had undermined France’s earlier wealth tax, requiring anyone who left France to keep paying the tax for five years after relocating abroad.
Supporters argued the tax could raise around 20 billion euros annually while affecting only about 1,800 households, according to a media report examining the proposal in detail. They pointed out that billionaires often pay proportionally less tax than middle-income earners, since much of their wealth sits inside holding companies rather than taxable income. Critics countered that taxing productive assets this heavily would discourage investment and push wealthy families to leave entirely.
LVMH chairman Bernard Arnault, France’s richest businessman, was blunt in his opposition, calling the plan “deadly for our economy” and warning that heavier taxation on entrepreneurs and investors would damage the country’s competitiveness, according to a media report on his remarks. The proposal passed the National Assembly last year but was blocked by the Senate, and was later defeated again during debate on the 2026 budget. It was ultimately replaced by the 2026 Finance Law, which introduced a narrower 20 per cent tax on luxury assets, yachts, private jets, sports cars and jewellery, held inside passive family holdings worth at least 5 million euros, rather than a broad wealth tax on total assets.
Not every economist agrees that taxation inevitably drives out the wealthy. French economist Thomas Piketty has argued that fears of capital flight are often exaggerated, and that greater international cooperation could make wealth taxes considerably more effective. Piketty maintains that decades of tax cuts for the richest households have fuelled today’s wealth inequality, and that carefully designed wealth taxes could reduce that inequality without seriously damaging investment. Critics respond that France has already tested many of these ideas before, and that even a relatively small number of departing entrepreneurs and investors can meaningfully drag down economic growth, since they are disproportionately likely to own businesses, finance new ventures and create jobs.
A pattern France has lived through before
This is not France’s first attempt at taxing serious wealth, and the country’s history with it offers a genuine cautionary tale. President François Mitterrand introduced the Solidarity Tax on Wealth, known as the ISF, in 1982, targeting the net assets of high-net-worth individuals. Over its lifetime, the tax brought in 63.5 billion euros, according to the European Commission, raising around 4.1 billion euros in its final year alone, 2017. But the same period saw an estimated 200 billion euros in capital flight, and French economist Eric Pichet calculated that the tax reduced annual GDP growth by roughly 0.2 per cent.
President Emmanuel Macron scrapped the ISF in 2017 and replaced it with a narrower Real Estate Wealth Tax, which applies only to individuals whose net real estate assets, excluding business holdings, exceed 1.3 million euros. That tax now raises roughly 1.1 billion euros a year, according to the French government, a fraction of what the ISF once generated.
There was also François Hollande’s so-called “Super Tax,” a 75 percent marginal income tax on annual earnings above 1 million euros, introduced as a way to force the wealthiest to help pull the country out of economic crisis. France’s highest court, the Constitutional Council, struck down the original version in late 2012, ruling the rate unfairly high. Hollande’s government revised the tax in the 2014 budget, shifting the burden from individuals to employers instead, making companies pay a 50 per cent tax on the portion of salaries above 1 million euros. The tax expired in 2015 after raising far less than expected, just 160 million euros in 2013 and 260 million euros in 2014.
That episode had its own high-profile departures. LVMH’s Bernard Arnault took out Belgian citizenship at the time, and actor Gérard Depardieu moved across the border to Belgium before later obtaining Russian citizenship. Public opinion on the tax was mixed. A majority of French taxpayers disapproved of the 75 per cent rate specifically, even though polls found six out of ten voters supported raising income taxes on the wealthy more generally.
Where the money is actually going
Several countries have positioned themselves deliberately to absorb the wealth leaving places like France. The United Arab Emirates remains one of the world’s biggest beneficiaries, thanks largely to its lack of personal income tax. In Europe, Italy has emerged as one of the continent’s biggest winners after Prime Minister Giorgia Meloni’s government introduced a 15 per cent flat-tax regime for qualifying foreign residents, letting eligible individuals pay a fixed annual tax on foreign income regardless of how much they actually earn abroad, a structure that has proven especially attractive to entrepreneurs and investors holding international assets.
Switzerland has long drawn wealthy residents through favourable tax arrangements for certain foreigners, while Monaco remains popular with Europe’s ultra-wealthy thanks to its complete absence of personal income tax. Portugal has also attracted thousands of wealthy migrants through its Non-Habitual Resident tax regime, though recent reforms have made that scheme considerably less generous than it once was.
A broader comparison using Henley & Partners’ 2026 Wealth Mobility Competitiveness Index found Italy, Switzerland and Greece emerging as some of Europe’s biggest beneficiaries of this migration, thanks to attractive tax regimes, political stability and investment opportunities, while France, Germany and the United Kingdom face growing pressure from tax reforms and fiscal uncertainty, according to a media report on the rankings. That same report noted some tax specialists caution against reading these migration figures too literally, arguing they work better as broad indicators of trend than as precise measurements of individual wealth flows.
A question every European government is now facing
France’s net loss of 800 millionaires remains, in raw numbers, a tiny fraction of its wealthy population. But it captures a much larger dilemma facing governments across Europe: how to raise the tax revenue needed to fund public services and address inequality, without pushing investment and capital toward countries willing to offer a more generous deal. As people and capital become steadily more mobile, that balance is only getting harder to strike, and France’s repeated attempts and reversals on wealth taxation, from Mitterrand’s ISF to Hollande’s Super Tax to this year’s Zucman proposal, suggest the country has yet to find an answer that survives contact with its own wealthiest citizens.
