The increase of wealth inequality in many EU countries has spurred interest in wealth taxation. While taxes on wealth for
a long time have played only a marginal role in the public finance and taxation literature, more recently a variety of arguments
are brought forward in favour of (higher) wealth taxation. At the same time, tax competition has led to an almost complete
disappearance of recurrent net wealth taxes in Europe. By dealing with non- and under-reporting in the Household and Consumption
Survey (HFCS) data set provided by the European Central Bank, we are able to estimate the wealth distribution within 20 EU
countries and the revenue potential of a progressive EU-wide net wealth tax.
