The personal income tax-benefit system influences, through marginal and average tax rates, income redistribution, labour supply, and tax evasion. In this paper we present, for the main taxpayer types and income levels the statutory and implicit marginal tax rates generated by the Italian personal income tax-benefit system components (social contributions, personal income tax, income type deductions, family-related deductions, family allowance, local surtaxes, and the "80 euro monthly bonus") along with the effective marginal tax rates deriving from their interaction. These tax rates are computed both for hypothetical taxpayer types (employee, retiree, self-employed with and without dependent family members) and using a microsimulation model based on a representative sample.The results show that the Italian tax-benefit system generates a broad range of effective marginal tax rates, with positive and negative values, determining, in some cases, also "poverty traps" (that is a marginal tax rates higher than 100 percent). The marginal and average tax rates are also sometimes decreasing with growing taxable income, while at a low level of income we have such high tax rates that a disincentive for labour supply may result. With this evidence, a correction of the Italian tax-benefit system appears desirable both to preserve a more efficient income redistribution as well as labour supply incentives.

Starting from the premise that Italian real estate taxation is inefficient and unnecessarily complex, the paper suggests two tax reforms. The first proposal puts forward progressive property taxation on the family basis; the second one suggests inferring a property income within the general calculation of the personal income tax. The common features of the two tax schemes are: the use of property market values instead of cadastral rents, a general reduction of the real estate local tax, a strong cutback of the stamp duties and registration fees applied to real estate transfers. A microsimulation model is employed to evaluate the impacts of the proposed taxation schemes. They both show, providing for a constant tax revenue, stronger redistributive effects.
