It is well known that the objectives of financial accounting and tax accounting sometimes conflict, resulting in book-tax differences (BTDs). In this study we test for associations between measures of BTDs and measures of market participants’ uncertainty regarding the information conveyed in financial reports. The measures of market participant uncertainty are: (1) share turnover, (2) analyst forecast dispersion, and (3) stock return variance. We find positive associations between levels and variability of total BTDs and the three measures. After disaggregating BTDs into their permanent and temporary components, we find that both are positively associated with market uncertainty, although the permanent component of BTDs is generally more strongly and consistently associated with measures of uncertainty than is the temporary component. We interpret these results, in part, as indicative of the possible effect of uncertainty contained in BTDs, especially permanent BTDs, on the precision of the information conveyed in the financial statements.
We examine whether financial expert audit committee members tailor their approach to overseeing the corporate tax planning process according to the firm's business strategy. We predict and find that such directors encourage defender‐type firms (characterized partially by high risk aversion) to engage in more tax avoidance activities and prospector‐type firms (characterized partially by innovation and risk seeking) to scale back on tax avoidance, relative to the opposing strategy type. We also find that both accounting experts and non‐accounting financial experts on the audit committee contribute to our results to some extent, although the effects of non‐accounting financial experts present more consistently. Overall, our results suggest that financial experts on the audit committee tend to play more of an advising role for defenders and more of a monitoring role for prospectors, relative to one another.
Using fi xed-effects models of state corporate income tax (SCIT) revenues that account for the endogeneity of apportionment formula weights and tax rates, we fi nd that states with a doubleweighted sales factor experience lower SCIT revenues than do states with an equally-weighted sales factor, while higher statutory tax rates are associated with higher SCIT revenues. We also fi nd that several other tax policies have statistically and economically signifi cant associations with SCIT revenues. Use of a throwback rule and defi ning business income more broadly are associated with higher SCIT revenues, while combined reporting surprisingly is not signifi cantly associated with SCIT revenues.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
