abstract: 'A flat tax rate on labour income has gained popularity in European countries. This article assesses the attractiveness of such a flat tax in achieving redistributive objectives with the smallest distortions to employment. We do so by using a detailed applied general equilibrium model for the Netherlands. The model is empirically grounded in the data and encompasses decisions on hours worked, labour force participation, skill formation, wage bargaining between unions and firms and a wide variety of institutional details. The simulations suggest that the replacement of the current tax system in the Netherlands by a flat rate will harm labour market performance if aggregate income inequality is contained. Only flat tax reforms that reduce redistribution will raise employment. This finding bolsters the notions from optimal tax literature regarding the equity-efficiency trade off and the superiority of nonlinear taxes to obtain redistributive goals in an efficient way.' affiliation: 'de Mooij, RA (Corresponding Author), Erasmus Univ, Tinbergen Inst \& Netspar, POB 1738, NL-3000 DR Rotterdam, Netherlands.
