Cryptocurrencies pose substantial challenges to tax enforcement due to their anonymous and decentralized properties, undermining conventional regulatory practices. We study the impact of an ambitious new enforcement initiative aimed at addressing these challenges: domestic third-party reporting...

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...

We study investors' responses to increasing tax reporting awareness and scrutiny in the crypto markets. We document significant taxation effects on investors' behavior and preferences for crypto exchanges using novel data on retail investors' trading. In relation to international peers,...

We show that the fiscal authorities of high-tax countries can lack the incentives to combat profit shifting to tax havens. Instead, they have incentives to focus their enforcement efforts on relocating profits booked by multinationals in other high-tax countries, crowding out the enforcement on...

The United States Internal Revenue Service (“IRS”) has repeatedly taken the position that, because the IRS does not ask taxpayers to identify their race or ethnicity on submitted tax returns, IRS enforcement actions are not affected by taxpayers' race or ethnicity. This claim, which I call...

This paper presents a new methodology to detect corruption in customs and applies it to Madagascar’s main port. Manipulation of assignment of import declarations to inspectors is identified by measuring deviations from random assignment prescribed by official rules. Deviant declarations are...

Beginning in the mid-seventeenth century, England changed its system of raising revenues from tax farming, combined with the granting of monopolies, to direct collection within the government administration. Rents were then transferred from tax farmers and monopolists to the central government...

It is often argued that even if optimal ex-post, settlement dilutes deterrence ex-ante. We analyze the interest for the tax authority of committing, ex-ante, to a settlement strategy. We show that to commit to the use of settlements is ex-ante optimal when the tax authority receives signals that...

The standard model of tax evasion based on the subjective expected utility maximization does not perform particularly well in econometric analyses: It predicts too little evasion and produces unsatisfactory econometric parameter estimates. The model is extended by looking at how the tax...

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...

For many emerging and developing economies, it is exceedingly difficult to constrain residents from evading tax liability on income from capital, whether earned domestically or abroad. Meanwhile, an international regime for combatting offshore tax evasion is emerging, and the form of the new...

Most legal and economics scholars recognize both that the government needs information about taxpayers’ transactions in order to determine whether their reporting is honest, and that third-party reporting helps the government obtain that information. Given governments’ reliance on tax funds,...

Standard compliance theory assumes that individuals evade to the extent it benefits them monetarily. However, a growing empirical literature suggests that many underlying cognitive considerations, including lying aversion, may play a non-trivial role when individuals make decisions.This study...

We study tax compliance under decentralized versus centralized tax enforcement. Using a tax administration reform in Canada, we examine which organizational level of tax enforcement leads to higher compliance. Our results show that there is more tax avoidance under centralized tax enforcement....

We describe the landscape of taxation in the crypto markets, especially that concerning U.S. taxpayers, and examine how recent increases in tax scrutiny have led to changes in trading behavior by crypto traders. We predict under a simple theoretical framework and then empirically document that...

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...

This paper studies the prevalence and consequences of size-dependent tax enforcement and compliance. The identification strategy uses the ranking of industries' average firm size in the United States as an instrument for the size ranking of the same industries in developing countries. Data on...

In 2008, the IRS initiated efforts to curb the use of offshore accounts to evade taxes. This paper uses administrative microdata to examine the impact of the enforcement efforts on taxpayers' reporting of offshore accounts and income. Enforcement caused approximately 60,000 individuals to...

We examine how U.S. individuals respond to regulation intended to reduce offshore tax evasion. The Foreign Account Tax Compliance Act (FATCA) requires foreign financial institutions to report information to the U.S. government regarding U.S. account holders. We first document a $7.8 billion to...
