In the second half of the 2010s more than 100 countries--including all large offshore financial centers--started to automatically exchange bank information with foreign tax authorities. This informational big-bang marks a break with the situation of offshore bank secrecy that prevailed before....

For most parameter values, increased randomness about how much taxable income an auditor would assess leads to higher reported income and more revenue, When reducing randomness is costly, optimality requires some randomness in assessed taxable Income. Even if reducing randomness g costless,...

This paper reviews recent economic research in tax compliance and enforcement. After briefly laying out the economics of tax evasion, it focuses on recent empirical contributions. It first discusses what methodologies and data have facilitated these contributions, and then presents critical...

Property taxes in developing countries are plagued by noncompliance and can exacerbate liquidity constraints. We characterize optimal enforcement and taxation policies as functions of revenue elasticities and measures of taxpayer hardship. We estimate these parameters using multiple sources of...

We examine two Pakistani programs to explore the role of deterrence as well as social and psychological factors in the tax compliance behavior of agents. In the first of these programs, the government began revealing income tax paid by every taxpayer in the country. The second program publicly...

Between 2020 and 2029, the IRS will fail to collect nearly $7.5 trillion of taxes it is due. It is not possible to calculate with precision how much of this "tax gap" could be collected. This paper offers a naïve approach. The analysis suggests that with feasible changes in policy, the IRS...

We use a new dataset consisting of the universe of Greek corporate tax returns matched to financial statements to study a voluntary tax compliance program for small firms. This "self-assessment" program prescribed target taxable profit margins for different types of activity. Firms that reported...

Why do some individuals choose to evade taxes while others do not? One popular view is that some individuals cheat on their taxes because they are more dishonest, selfish, or perceive different social norms. There is, however, little direct evidence on this matter. In collaboration with the...

There is a large literature showing that the self employed underreport their income to tax authorities. In this paper, we quantify the extent to which the self employed systematically underreport their income to U.S. household surveys. To do so, we use the Engel curve describing the relationship...

A recent literature has studied bunching at notches in tax systems; but work on the implications of bunching for welfare has been limited. We consider a setting where there are discrete changes in the enforcement of tax compliance at certain levels of reported income, creating notches that can...
