In absence of third-party reporting, taxpayers are required to self-report information with various degrees of detail, ranging from uncorroborated claims to comprehensive records with receipts. Using a quasi-experimental design applied to noncash charitable contribution deductions, I show that...

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...

We explore bunching at U.S. income tax kinks using a panel of 258 million tax returns from 1996 to 2014. We find bunching at seven kinks, with nearly all bunching occurring at kinks maximizing tax credits. In our sample period, the total number of bunchers increased at an 11 percent annualized...

Using a panel of household level tax data, we estimate the degree to which dependents are "reassigned" between tax units within households, and how these reassignments affect combined tax liabilities. Reassigning dependents reduces combined tax liabilities on average, suggesting some household...

This paper estimates the elasticity of taxable income (ETI) for Spain. Using the bunchingapproach and administrative tax data from 2008 to 2017, we find evidence of bunching atthe first tax kink (ETI=0.7) and missing mass around the second tax kink (ETI=0.4). Eventhough we detect heterogeneity...

I explore labor supply responses to an unusually large and salient notch generated by the “Mini-Job” program in Germany. Using administrative data, I document three findings. First, despite the unusually large magnitude of incentives, earnings elasticities are modest, even after accounting...

The role of tax incentives in charitable giving has seen considerable attention. Yet, attention is limited to direct tax incentives, such as tax deductibility. Whether and how taxing household savings affects charitable giving is largely unexplored. While theory suggests a link, the sign of the...

The parsonage exemption allows “ministers of the gospel” to exclude the value of housing benefits from income, whether received in-kind or as a cash allowance. Critics argue that the provision violates the First Amendment's Establishment Clause, while supporters contend that it does not...

Given the increased availability of survey income data, in this paper we analyse the pros and cons of alternative data sets for static tax-benefit microsimulation in Italy. We focus on all possible alternatives, namely using (a) SHIW or (b) IT-SILC data using a consistent net-to-gross...
