In this paper, we present a review of tax research. We survey four main areas of the literature: (1) the informational role of income tax expense reported for financial accounting, (2) corporate tax avoidance, (3) corporate decision-making including investment, capital structure, and organizational form, and (4) taxes and asset pricing. We summarize the research areas and questions examined to date and what we have learned or not learned from the work completed thus far. In addition, we provide our opinion as to the interesting and important issues for future research.

ABSTRACT: This study investigates whether individual top executives have incremental effects on their firms’ tax avoidance that cannot be explained by characteristics of the firm. To identify executive effects on firms’ effective tax rates, we construct a data set that tracks the movement of 908 executives across firms over time. Results indicate that individual executives play a significant role in determining the level of tax avoidance that firms undertake. The economic magnitude of the executive effects on tax avoidance is large. Moving between the top and bottom quartiles of executives results in approximately an 11 percent swing in GAAP effective tax rates; thus, executive effects appear to be an important determinant in firms’ tax avoidance.
