Product market power provides firms with comparative advantages through more persistent profitability and insulation from competitive threats. These advantages likely provide firms with the ability to engage in greater tax avoidance. We present evidence consistent with this hypothesis. We also show that firms mimic the tax outcomes of their product market leaders. Among firms with greater product market power and comparatively high cash tax avoidance, we find stock prices to be less informative and that investors require additional compensation for the risks associated with comparatively high cash tax avoidance. Our results survive numerous robustness tests. Overall, our results suggest that industry dynamics, particularly related to a firm's competitive position, play a meaningful role in corporate tax policy.
We examine whether firms decrease tax reserves to meet analysts’ quarterly earnings forecasts in the period prior to FIN 48, and whether that behavior changed following FIN 48. We use analysts’ forecasts of pretax and after‐tax income to impute premanaged earnings, or earnings before any tax manipulation. Pre‐FIN 48, we observe that firms reduce their tax reserves (i.e., increase income) when premanaged earnings are below analysts’ forecasts. Specifically, 78 percent of firm‐quarters that would have missed the analyst forecast if not for the tax reserve decrease, meet that target when the decrease is included. Furthermore, we find a significant positive association between the decrease in tax reserves and the deviation of premanaged earnings from analysts’ forecasts. In contrast, post‐FIN 48, we find no evidence that firms use changes in tax reserves to manage earnings to meet analysts’ forecasts. Thus, our results suggest that FIN 48 has, at least initially, curtailed firms’ use of tax reserves to manage earnings.
This study examines the tax avoidance behavior of firms prior to the issuance, and following the resolution, of SEC tax comment letters. We find that firms that appear to engage in greater tax avoidance are more likely to receive a tax-related SEC comment letter. We also find that firms receiving a tax-related SEC comment letter, relative to firms receiving a non-tax comment letter, subsequently decrease their tax avoidance behavior consistent with an increase in expected tax costs. Additionally, we document evidence consistent with other firms that do not receive a comment letter reacting to multiple publicly disclosed tax-related comment letters within their industry by increasing their reported GAAP ETR, consistent with an indirect effect of regulatory scrutiny on certain types of tax avoidance.
Internal controls influence information quality, thus affecting the ability of supply chain partners, who rely on collaborative systems of information sharing, to reliably contract. Using SOX-related internal control assessments as a proxy for internal control quality and U.S. GAAP-mandated major customer disclosures, we find that supplier internal control quality influences supply chain relationship duration. Specifically, our evidence demonstrates that: (1) poor internal control quality increases the likelihood of subsequent customer-supplier relationship termination; (2) timely control weakness remediation attenuates termination likelihood; and (3) weaknesses affecting customer contracting drive the effect of internal control quality on relationship termination. Our results control for supplier operational quality and performance, and are robust to propensity score matching techniques, controls for reverse causality, and alternative proxies for relationship termination and internal control quality. Overall, our findings are consistent with customers viewing strong supplier controls as important, albeit overlooked, contracting elements with significant implications for supply chain relationships.
Using a new hand-collected database on state department of revenue (DOR) expenditures, this study examines the association between changes in state corporate tax enforcement expenditures and state-level tax collections during the 2000–2008 time period. The results, after addressing endogeneity concerns using a changes specification and state fixed effects, suggest a $1 increase (decrease) in current period corporate enforcement is associated with an $8 to $11 increase (decrease) in state tax collections two years into the future. The association appears to be attenuated in states with restrictive tax policies (i.e., unitary/combined reporting and related-party add-back provisions) suggesting that enforcement and restrictive tax policies could serve as substitutes. JEL Classifications: H26; H71; H72. Data Availability: Enforcement data were hand collected from state revenue department annual reports and by contacting state corporate income tax personnel. All annual reports are publicly available.
