Accounting for tax evasion profiles and tax expenditures in microsimulation modelling, The BETAMOD model for personal income taxes in Italy.(ISSN: 1827-3580 No. 24/WP/2015). Working Paper – Department of economics, Ca’ Foscari, University of Venice
The paper presents the main characteristics of BETAMOD, a static microsimulation model that reproduces the Italian personal income tax (IRPEF), as well as local income taxes, namely the regional and municipal additional income taxes, building on a detailed reconstruction of tax legislation. With respect to the vast majority of existing tax microsimulation models, the peculiarities of BETAMOD concern two aspects: the inclusion of a detailed set of tax expenditures, and the estimation of individual-specific tax evasion rates, which account for the total individual income level, its composition in terms of income sources, and the geographical area of residence.
