The Distribution Effects of Taxes on Pensions and Unemployment Benefits in the EU-15

Research has shown that the tax treatment of replacement incomes differs considerably among countries. Consequently, the ranking of countries by expenditure level is different for gross and net social expenditures. On a micro level this is translated into a gap between gross and net benefits; this gap varies among countries. In this chapter, we use EUROMOD for an international comparison of the difference between gross and net benefits at the micro level. We investigate the distribution effects of the income tax treatment of replacement benefits, focusing on old-age pensions and unemployment benefits. We present a summary overview of the different ways of levying taxes on benefits in the pre-2004 EU-15 countries. We then try to answer the question how the tax treatment of social security benefits affects the distribution of these benefits and how progressive taxes on benefits are compared to taxes on earnings.
