Abstract: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.

A Review of Tax Research
IntroductionIn this paper, we review tax research in accounting as well as tax research in economics and finance to the extent that it is related to or is affected by research in accounting. Shackelford and Shevlin (2001) provide a careful and thorough review of empirical tax research in accounting in the prior Journal of Accounting and Economics review volume. Shackelford and Shevlin limit their review to research published in accounting outlets and describe the development of the relatively young archival, microeconomic-based income tax literature that arose from the Scholes andWolfson framework. In his discussion of the review, Maydew (2001) emphasizes the need for tax researchers in accounting to think more broadly and to incorporate more theory and evidence from economics and finance. We agree. Tax research has a long history in many disciplines; this fact cannot be ignored. Our goal in this paper is to integrate the theoretical and empirical tax research from accounting, economics, and finance, to summarize what is known and unknown, and to offer suggestions for future research.The multidisciplinary nature of tax research is what makes tax research exciting (yes, exciting), yet difficult. Tax research can be difficult not only because one has to follow tax studies in accounting, finance, economics, and law (through academic institutions, governmental agencies, and policy think tanks), but also because different disciplines often use different languages and have different perspectives. 1 For example, economists generally focus on tax compliance, tax incidence (such as who bears the corporate tax), investment and economic growth effects (such as how taxes 1 Slemrod (1992a) characterizes these differences as economists studying what corporations actually do and accountants stud...
