Here you will find a wealth of information on key taxation indicators that allow the assessment of tax systems from several angles (by type of tax, by economic function, by level of government, ITR, etc.) for all EU Member States and the EU a whole, as well as Iceland and Norway. The data are presented in different formats (specific indicators for all countries and summary tables by country) for the period 2009-2021. These indicators are supported by a strong methodology developed over the years (see General methodological notes). The data and indicators presented rely upon the valuable contributions by experts from the ministries of finance in all the countries covered by this data collection and indicator computation exercise.
