    This paper presents the tax-benefit microsimulation model for the Polish economy developed at the Polish Ministry of Finance. The tool has been designed to enable the ex ante regulatory impact assessment of fiscal and social policy. Proposed regulatory changes are evaluated along two dimensions – financial and distributional. As of yet, the model is of a static type and is able to capture only first round (on impact) effects. However, by employing the nearest neighbour algorithm, behavioural responses in terms of consumption patterns have been incorporated. The microsimulation model is also to be supplemented with a labour supply module and eventually integrated with a CGE-type model, so as to quantify the macroeconomic consequences of tax and benefit policy design. This paper describes the scheme of the model, the underlying model assumptions, goodness of fit to the data and some examples of application.
