We examine whether firms hold more cash in the face of tax uncertainty. Because of gray areas in the tax law and aggressive tax avoidance, the total amount of tax that a firm will pay is uncertain at the time it files its returns. The tax authorities can challenge and disallow the firm’s tax positions, demanding additional cash tax payments. We hypothesize that firms facing greater tax uncertainty hold cash to satisfy these potential future demands. We find that both domestic firms and multinational firms hold larger cash balances when subject to greater tax uncertainty. In terms of economic significance, we find that the effect of tax uncertainty on cash holdings is comparable to that of repatriation taxes. Our evidence adds to knowledge about the real effects of tax avoidance and provides a tax-based precautionary explanation for why there is such wide variation in cash holdings across firms.

Despite decades of research on how, why, and when companies manage earnings, there is a paucity of evidence about the geographic location of earnings management within multinational firms. In this study, we examine where companies manage earnings using a sample of 2,067 U.S. multinational firms from 1994 to 2009. We predict and find that firms with extensive foreign operations in weak rule of law countries have more foreign earnings management than companies with subsidiaries in locations where the rule of law is strong. We also find some evidence that profitable firms with extensive tax haven subsidiaries manage earnings more than other firms and that the earnings management is concentrated in foreign income. Apart from these results, we find that most earnings management takes place in domestic income, not foreign income.

Tax audits are a necessary component of the tax system, but policymakers and others have expressed concerns about their potentially adverse real effects. Understanding the causal effects of tax audits has been hampered by lack of data and because typically tax audits are not randomly assigned. We use administrative data from random tax audits of small businesses to examine the real effects of being subject to a tax audit. We find that audited firms are more likely to go out of business following the audit. The effect is concentrated in firms that underreport their taxes, although we find some evidence that the administrative costs of an audit also negatively affect firm survival. Among firms that continue as going concerns, we find evidence that audits have adverse effects on future revenues but no effect on future wages, employment, or investment. Finally, we find that tax audits have side benefits, causing firms to make changes to improve their tax efficiency.

We compare executive equity incentives of firms accused of accounting fraud by the Securities and Exchange Commission (SEC) during the period 1996–2003 with two samples of firms not accused of fraud. We measure equity incentives in a variety of ways and employ a battery of empirical tests. We find no consistent evidence that executive equity incentives are associated with fraud. These results stand in contrast to assertions by policy makers that incentives from stock-based compensation and the resulting equity holdings increase the likelihood of accounting fraud.

We describe the taxation landscape in the cryptocurrency markets, especially concerning U.S. taxpayers, and examine how recent increases in tax scrutiny have led to changes in crypto investors' trading behavior. We argue conceptually and then empirically document that increased tax scrutiny leads crypto investors to utilize conventional tax planning with tax-loss harvesting as an alternative to non-compliance. In particular, domestic traders increase tax-loss harvesting following the increase in tax scrutiny, and U.S. exchanges exhibit a significantly greater amount of wash trading. Additional findings suggest that broad-based and targeted changes in tax scrutiny can differentially affect crypto traders’ preference for U.S.-based exchanges. We also discuss other gray areas for tax regulation related to new crypto assets, such as Non-Fungible Tokens and Decentralized Finance protocols, that further highlight the importance of coordinating tax policy and other regulations.

We examine whether mandatory tax information exchange agreements between governments have real effects on firms’ physical trade in tangible goods. We posit that some of the physical trade in tangible goods flowing through low-tax jurisdictions is intended to facilitate income shifting. As such, shocks to enforcement via mandatory information exchange agreements could cause firms to change the physical flow of goods. Using firm-level shipping container data, we find that adoption of bilateral tax information exchange agreements (TIEAs) between the U.S. and foreign jurisdictions is associated with significant decreases in the volume of imports by U.S. firms from those jurisdictions. We also find reallocation effects: U.S. firms increase imports from jurisdictions in the same subregion as the treated jurisdiction, resulting in minimal overall change in total imports. To our knowledge, ours is the first study to document a connection among enforcement-related tax disclosure, income shifting, and physical trade flows.

We investigate the relation between tax avoidance and tax uncertainty, where tax uncertainty is the amount of unrecognized tax benefits recorded over the same time period as the tax avoidance. On average, we find that tax avoiders, i.e., firms with relatively low cash effective tax rates, bear significantly greater tax uncertainty than firms that have higher cash effective tax rates. We find that the relation between tax avoidance and tax uncertainty is stronger for firms with frequent patent filings and tax haven subsidiaries, proxies for intangible-related transfer pricing strategies. The findings have implications for several puzzling results in the literature.

We investigate whether firms in close customer–supplier relationships are better able to identify and implement tax avoidance strategies via supply chains. Consistent with our prediction, we find that both principal customers and their dependent suppliers avoid more taxes than other firms. Further analysis suggests that principal customers and dependent suppliers likely engage in tax strategies involving shifting profits to tax haven subsidiaries. Moreover, tax benefits appear to explain both principal customer firms’ and dependent supplier firms’ organizational decisions. Overall, our study provides evidence of the importance of tax avoidance as a source of gains from these relationships.

We empirically investigate one form of illegal investor‐level tax evasion and its effect on foreign portfolio investment. In particular, we examine a form of round‐tripping tax evasion in which U.S. individuals hide funds in entities located in offshore tax havens and then invest those funds in U.S. securities markets. Employing Becker's ( ) economic theory of crime, we identify the tax evasion component by examining how foreign portfolio investment varies with changes in the incentives to evade and the risks of detection. To our knowledge, this is the first empirical evidence of investor‐level tax evasion affecting cross‐border equity and debt investment.
