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...

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...

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...

We estimate the returns to IRS audits of taxpayers across the income distribution. We find an additional $1 spent auditing taxpayers above the 90th income percentile yields more than $12 in revenue, while audits of below-median income taxpayers yield $5. We draw upon comprehensive internal...

In a July 2020 report, the Congressional Budget Office estimated that modest investments in the IRS would generate somewhere between $60 and $100 billion in additional revenue over a decade. This is qualitatively correct. But quantitatively, the revenue potential is much more significant than...

Using data on trust and trustworthiness from the 1990 wave of the World Values Survey, I first investigate a model of the extent of tax cheating and the size of government that recognizes the interdependence of the two. The results reveal that tax cheating is lower in countries that exhibit more...
