I reexamine the conflicting results in Frank, Lynch, and Rego (2009) and Lennox, Lisowsky, and Pittman (2013). Frank et al. (2009) conclude that firms can manage book income upward and taxable income downward in the same period, implying a positive relation between aggressive book and tax reporting. Lennox et al. (2013) conclude the relation is negative and aggressive book reporting informs users that aggressive tax reporting is less likely. I identify four key differences in the research designs across the two studies, including measures of aggressive book reporting, measures of aggressive tax reporting, sample time periods, and empirical models. I systematically examine whether each of these differences is responsible for the conflicting results by altering the key difference while holding other factors as constant as possible. I find the relation between aggressive book and tax reporting is driven by the measure of aggressive book reporting, as the relation is positive for some subsets of firms and negative for others. Firms accused of financial statement fraud have a negative relation while nonfraud firms exhibit a positive relation. Using discretionary accruals, I also look for, but do not find a “pivot point” in the relation between aggressive book and tax reporting. I provide a better understanding of the relation between aggressive book and tax reporting by identifying research design choices that are responsible for prior results. I show that measures of both discretionary accruals and financial statement fraud are necessary to gain a more complete picture of the relation between aggressive book and tax reporting.

We investigate the interaction of debt covenants and tax accounting on the adoption of Financial Interpretation No. 48 (FIN 48). We examine how firms respond to the potential tightening of covenant slack upon FIN 48 adoption and whether these actions are penalized by creditors and anticipated by equity markets. We find that upon FIN 48 adoption, the majority of sample corporate borrowers increase their tax reserves and reduce equity. Firms close to debt covenant violation were even more likely to increase tax reserves upon FIN 48 adoption; however, the size of the adjustment was relatively smaller, suggesting that the FIN 48 standards limited, but did not eliminate, firms use of discretion in reporting uncertain tax positions to avoid costly covenant violations. For firms near net worth debt covenant violation, the act of decreasing equity upon FIN 48 adoption imposes real economic costs, as the average cost of debt increased by 43 basis points. Finally, we extend prior research on the market response to FIN 48 by showing how the market response to FIN 48 adoption is a function of debt covenant slack and tax aggressiveness. Specifically, the cumulative abnormal return at the FIN 48 exposure draft release date is negative only for tax aggressive firms that are close to debt covenant violation.

This paper examines the relationship between environmental uncertainty and tax avoidance at the firm level. We posit that managers faced with more uncertain environments are likely to engage in more tax avoidance activities. We find a significant and negative relationship between environmental uncertainty and effective tax rates, and our results persist through a battery of robust checks. We further find that managerial ability mitigates the above relationship. Moreover, we find that small, highly leveraged, and innovative firms operating in uncertain environments engage in more tax avoidance.

This paper takes a unique approach to provide additional insight into the agency view of tax avoidance. We directly investigate the association between the presence of agency conflicts and corporate tax avoidance. Using a measure of CEO centrality, developed by Bebchuk, Cremers, and Peyer (2011), we identify settings in which agency conflicts are likely to be high. In contrast to prior literature, our primary tests do not rely on the inferences of market participants regarding tax avoidance. We find that CEO centrality is positively and significantly associated with tax avoidance. Additionally, we analyze the mediating role of monitoring by institutional investors in our setting. We find that the relation between tax avoidance and the existence of agency conflicts is strongest for firms with low levels of CEO monitoring. We also add to prior literature by investigating the implications of our setting on future accounting performance and future firm value.

To better detect potential audit issues, since 2010, the Internal Revenue Service has required firms to file a separate schedule individually disclosing each of their uncertain tax positions (UTPs). This study uses an experiment to examine how this increase in detection risk from the newly created IRS schedule influences both a firm’s tax reporting and financial reporting concurrently. We find that corporate tax professionals were more likely to recommend an UTP when their firm had a strong UTP reporting quality, regardless of the detection risk level of the reporting environment. However, we find an interaction effect for the recording of the tax reserve. In a low detection risk environment, corporate tax professionals recorded a higher (lower) tax reserve when their firm had a weak (strong) UTP reporting quality. However, in a high detection risk environment, corporate tax professionals recorded a lower (higher) tax reserve when their firm had a weak (strong) UTP reporting quality. Overall, the results provide insight into the dual nature of UTP reporting and the determinants that influence each reporting behavior.

The purpose of this chapter is to discuss the relation between tax reporting and financial reporting, their influence on transparency, and empirical implications.

In view of the recent enhanced concerns of the SEC and PCAOB that Accounting Principles Board Opinion No. 23 (APB 23)–asserting firms do not comply with the “sufficient evidence” criteria of APB 23, we examine whether APB 23–asserting firms that declared their foreign earnings as permanently reinvested abroad are less likely to repatriate those foreign earnings under the American Jobs Creation Act (AJCA) of 2004, compared with similar non-asserting firms. The asserting firms are required to disclose sufficient evidence that validates an ability to meet their domestic cash needs with only earnings generated in the United States and their plans to indefinitely reinvest foreign earnings outside the United States. Estimates show that asserting firms are more likely to repatriate their foreign earnings than non-asserting firms. In addition, we find that the probability of making an election to repatriate permanently invested foreign earnings under the AJCA of 2004 is higher for firms with nonbinding foreign tax credit (FTC) limitations that have made an APB 23 declaration to permanently invest foreign earnings abroad. These findings suggest that asserting firms’ declarations to indefinitely reinvest foreign earnings abroad are not well grounded, thereby indirectly validating the SEC’s and PCAOB’s increased scrutiny for supporting evidence for APB 23 assertion. The estimates also show that the likelihood of making an election to repatriate foreign earnings under the AJCA of 2004 increases with asserting firms’ liquidity constraints and financial distress: the financial characteristics listed as part of APB 23 criteria of sufficient evidence and highlighted by the SEC and PCAOB comment letters, indicating that asserting firms raid permanently reinvested foreign earnings to satisfy their financial needs and constraints.

This study examines how creditor interventions after debt covenant violations affect corporate tax avoidance. Using a regression discontinuity design, we find that creditor interventions increase borrowers' tax avoidance. This effect is concentrated among firms with weaker shareholder governance before creditor interventions and among those with less bargaining power during subsequent debt renegotiations. Our results indicate that creditors play an active role in shaping corporate tax policy outside of bankruptcy.

We investigate how different cognitive conceptualizations of reference point and tax withholdings jointly influence aggressive tax filing. We utilize a field study with responses captured from actual taxpayers immediately after filing their returns. Consistent with both prospect theory and mental accounting perspectives, we hypothesize and find evidence that more aggressive filing decisions depend on mental categorization of whether taxpayers expect a tax refund or owe additional taxes relative to their expected asset position (EAP). We find a joint and additive impact of EAP with a cognitive link made between taxes and the categorization of amounts owed. Our findings suggest that more aggressive filing behavior is found in taxpayers in a tax loss position relative to their EAP and in those that do not separately categorize taxes owing from their own resources. By highlighting the importance of EAP and the cognitive separation of taxes owed, we provide insight for revenue agencies to use cognitive framing strategies to mitigate aggressive taxpayer behavior. The cognitive framing of EAP may be influenced by the use of installment payments and tax withholdings, but also may be affected by communications that alter taxpayers' expectations of taxes owed.

This study examines short selling as one external determinant of corporate tax avoidance. Prior research suggests that short sellers have information advantages over retail investors, and high short-interest levels are a bearish signal of targeted stock prices. As a result, when short-interest levels are high, managers have been shown to take actions to minimize the negative effect of high short interest on firms’ stock prices. Tax-avoidance activities may convey a signal of bad news (i.e., high stock price crash risk). We predict that, when short-interest levels are high, managers possess incentives to reduce firm tax avoidance in order to reduce the associated stock price crash risk. Consistent with this prediction, we find that short interest is negatively associated with subsequent tax-avoidance levels. This effect is incremental to other factors identified by prior research. We conclude that short selling significantly constrains corporate tax avoidance.
