Key Findings

•  The gap between statutory rates and average effective tax rates for personal income tax (PIT) in
   the European Union varies significantly, affecting the efficiency and simplicity of the tax system.
 • Simplified tax systems, with fewer deductions and exemptions, combined with broader bases help
   reduce tax avoidance while improving efficiency in revenue collection.
 • Those EU Member  States with a smaller gap between statutory and average effective tax rates for
   PIT enjoy higher tax competitiveness, which in turn helps drive investment and economic growth.
 • Increasing tax rates without simplifying the system may not always result in a proportional in-
   crease in tax revenues, due to changes in incentives and their effect on taxpayer behavior.
 • Keeping marginal and average effective tax rates as aligned as possible reduces economic distor-
   tions and facilitates tax certainty for companies and individuals, improving the efficiency of the tax
   system and reducing its negative impact on production.
 • EU Member  States like Spain and Germany have reached a high tax rate threshold. As a result, ad-
   ditional increases in statutory rates for PIT do not generate a significant increase in tax revenues, a
   scenario that may be described as a Laffer Curve effect.


















        The mission of Tax Foundation Europe is to improve lives through tax policies that lead to greater economic growth and opportunity.
