Global wealth tax on ultra-rich ‘would raise up to $250bn a year’
The TelegraphMr Zucman, whose PhD supervisor was Thomas Piketty, the Left-wing “rock star” economist, said: “There is now clear evidence that contemporary tax systems, instead of being progressive, do not effectively tax the wealthiest individuals. “Ultra-high-net-worth individuals tend to pay less in tax relative to their income than other social groups, regardless of the specific tax design choices and enforcement practices of countries.” The Labour Party has ruled out a tax on wealth, but is reported to be drawing up ways to raise more from assets, potentially through capital gains taxes or inheritance tax, which could be implemented after the election. Most countries tend to charge higher rates of tax for higher earners, but Mr Zucman’s studies of France and the Netherlands indicate that for the extremely rich, effective tax rates drop close to zero. However, Mr Zucman said that the global minimum corporation tax, which comes into force this year, shows countries can cooperate to make the policy work, preventing the rich from fleeing the levy.
