Does a wealth tax raise less revenue than it costs?
Core argument: France's wealth tax, levied at a top rate of 1.5%–1.8% on fortunes above €13m ($14.3m), raised only a few billion euros at its peak, about 1% of total tax revenue.
France's wealth tax, implemented from 1982-1986 and 1988-2017, imposed a top rate of 1.5%-1.8% on fortunes over €13m ($14.3m), raising only a few billion euros at its peak, or about 1% of total tax revenue. However, it led to the exodus of at least 10,000 wealthy individuals, primarily to Belgium, resulting in a significant loss of income and other taxes. French economist Eric Pichet estimated that the wealth tax cost the government nearly twice the revenue it generated. This outcome highlights the potential pitfalls of high wealth taxes, as the loss of affluent taxpayers can outweigh the benefits, suggesting that broader tax strategies might be more effective in addressing inequality without causing capital flight.
