This document provides a summary of tax burdens for typical workers in the EU-27 countries in 2011. The main results showed that taxes are rising in Europe and are largely invisible to employees. Countries with flat tax policies saw some tax relief for workers, but total taxes remained higher than in countries with progressive tax systems. Belgium had the highest tax burden, while Cyprus had the lowest. The document defines key terms, outlines the methodology, and provides tax data and calculations for each EU country.
