Do wealth taxes raise enough revenue to be worth keeping?
Core argument: By 2017, only four high-income countries—France, Norway, Spain, and Switzerland—still levied wealth taxes, down from 12 in 1990.
By 2017, only four high-income countries—France, Norway, Spain, and Switzerland—retained wealth taxes, down from 12 in 1990. The OECD reported that in 2016, tax revenues from individual net wealth taxes ranged from 0.2% of GDP in Spain to 1.0% in Switzerland, with these taxes contributing just 0.5% to 3.7% of total tax revenues. Switzerland is an exception, using wealth taxes as a substitute for property taxes, resulting in higher revenue. The limited revenue generated by wealth taxes has led many countries to abandon them, questioning their efficacy and administrative burden. This trend suggests that a US wealth tax targeting individuals with over $50m may not yield significant revenue, reflecting broader global skepticism about the financial impact of such taxes.
