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....

This paper studies tax evasion at the top of the U.S. income distribution using IRS micro-data from (i) random audits, (ii) targeted enforcement activities, and (iii) operational audits. Drawing on this unique combination of data, we demonstrate empirically that random audits underestimate tax...

The U.S. Supreme Court decision in the landmark 2018 Wayfair case greatly improved state governments' ability to enforce collection of sales taxes on a destination basis. This has reduced state tax competition with an essentially-untaxed internet, but has brought traditional cross-border...

We study the extent to which ML techniques can be used to improve tax auditing efficiency using administrative data, without the need of randomized audits. Using Italy's population data on sole proprietorship tax returns, audits and their outcome, we develop a new approach to address the so...

We provide a unified analysis of taxation and taxpayer education when individuals have an incomplete understanding of a complex tax system. The analysis is independent of whether income is earned legitimately, or by avoiding or evading taxes. In this sense, learning about tax minimization...

This paper studies the welfare effects of international investment to evade domestic taxes on domestic investment income. Capital mobility for tax evasion eliminates distortions in the intertemporal allocation of consumption, but introduces distortions in domestic production. Conversely, a...

When tax structure changes, people may alter their consumption basket, but they also may call and give new instructions to their accountant, change their reports to the IRS, change the timing of transactions, and undertake a range of other actions that do not directly involve a change in their...

This paper uses time-series data to investigate how changes in capital gains tax rates affect taxpayer compliance. It finds that a one percent increase in the marginal tax rate reduces voluntary compliance by between one half and one percent. These results confirm the findings of previous...

This paper attempts to estimate the size and distribution of tax evasion in rich countries. We combine random audits--the key source used to study tax evasion so far--with new micro-data leaked from large offshore financial institutions--HSBC Switzerland ("Swiss leaks") and Mossack Fonseca...

A large literature explores crowd out in situations where public goods are jointly provided; work in this area typically depicts a tax system where individuals take taxes as given. But in some settings, such as those in developing economies, efforts to evade or avoid taxes may be widespread. Using...
