L'assegno unico e universale e la revisione dell'IRPEF del 2022: un'analisi di equità ed efficienza per le famiglie di lavoratori dipendenti (the unique and universal familiy allowance and the revision of personal income tax in Italy: an equity and efficiency analysis for employees)

In 2022, two measures were introduced that modified the Italian tax-benefit system: the first revised the structure of the personal income tax (PIT), while the second introduced a new family allowance («Assegno Unico e Universale – AUU») for households with children under 21 years of age. This work aims to show the specific and joint effect of the two interventions in terms of equity and efficiency, focusing on labour supply of women by using the new behavioural microsimulation model TAXBEN-DF (II), developed by the Department of Finance of the Italian Ministry of Economy and Finance. The results show appreciable redistributive effects, due to a progressive tax design of the new family allowance scheme. The analysis of the potential change in the labour supply of women shows that the AUU can lead to a negative variation for single women and a positive one for women in couples. Conversely, the revision of PIT marginal rates, by favouring the middle-upper income classes, may induce a positive average change in the female labour supply for both single women and women in couples.
