Welfare state regimes vary in their strategies of redistribution. Some welfare states have extensive taxable social insurance schemes, while others rely more on non-taxable means-tested benefits. In order to assess the distributive effects of different programme types, it is necessary to analyse social insurance after taxes, something rarely practised in comparative research. In this paper, we evaluate distributive effects of social insurance after taking taxes into account in 10 welfare states. The main question is to what extent income taxes affect the contribution of social insurance to income inequality. The conclusion is that taxation may have important consequences for both inter- and intra-country comparisons of income redistribution, especially if countries with similar social policy systems are compared. The analyses are based on micro-level income data from the Luxembourg Income Study (LIS).
