The existing literature documents mixed evidence toward the association between corporate social responsibility (CSR) and corporate tax planning (e.g., Davis, Guenther, Krull, & Williams, 2016; Hoi, Wu, & Zhang, 2013). In this study, I aim to identify a causal relationship between CSR and tax planning, leveraging the staggered adoptions of constituency statutes in US states, which is a plausibly exogenous shock to firms' emphasis on their social responsibility. In general, the statutes permit firm directors to consider the interests of all constituents when making business decisions, including those who benefit from firms paying their fair share of income taxes. Thus, the adoption of the statutes raises the importance of firms' social responsibility in paying income taxes. Employing a staggered difference-in-differences (DiD) method, I find that firms incorporated in states that have adopted constituency statutes exhibit significantly higher effective tax rates (ETRs) based on current tax expense. This causal relationship suggests that managers, with the legitimacy to consider the social impact of tax avoidance, become less aggressive in tax planning. I further find that the effect of adoption is stronger for financially unconstrained firms and firms in retail businesses, where the demand (cost) for tax avoidance is lower (higher). Finally, I show that my main results are driven by firms located in states with a high sense of social responsibility and firms with high levels of tax avoidance prior to the adoption. Overall, the findings in this chapter contribute to the literature by delineating a negative causal relationship between CSR and tax avoidance and identifying a positive social impact brought by the passage of constituency legislation.

This paper aims to examine the design of optimal incentives for a firm’s tax department in the presence of information asymmetry.

This paper provides a theoretical model to examine the design of optimal incentives. The focus is on a situation in which a risk-averse tax department has private information about its efficiency type or effort to be exerted before the firm sets the incentive schemes.

This paper shows that a tax department’s risk aversion leads to a decline in the fraction of the cost borne by the tax department. It also shows that the optimal contract schemes should be designed to filter out as much uncontrollable risk as possible by using third-party information relevant to a tax department’s realized cost.

It contributes to a better understanding of the impact of corporate incentive plans on firms’ tax practices. This study, by designing a theoretical model, helps explain why there exist differences in tax planning across firms based on the finding that incentives for tax planning activities differ across firms.

This paper is the first study that considers the situation in which tax managers’ risk-averse and types, as well as relevant information collected by the firms, can be used to set up incentive schemes and investigates whether and how the incentive schemes will be affected when firms improve their prior information by acquiring relevant information before the tax department acts.

This study aims to use research setting provided by the implementation of Financial Accounting Standards Board Interpretation 48 (FIN48) to help develop a further understanding of large positive book–tax differences (LPBTD) and their relationship with earnings persistence. Extant literature indicates that the tax information provided in financial statements, such as large book–tax differences, is useful for detecting earnings management and signals less persistent future earnings. However, more information is needed about the causes of large book–tax differences and their abilities to signal the differences in earnings persistence (Blaylock et al., 2012).

In the first step, temporary book–tax differences are ranked by quintiles based on the approach in Hanlon’s (2005) study and the highest quintile in the sample observations are designated as large positive temporary book–tax differences (LPBTD). In the second step, differences in the persistence of earnings for high tax-planning firms as measured by UTB_NonETR are searched for. In further testing, an ordered logistic model and the Vuong (1989) test are applied to compare both the incremental and the relative ability of UTB_NonETR and Cash-ETR to explain the ranking order of temporary book–tax differences.

The negative relation between temporary differences and earnings persistence is moderated by the level of tax planning as measured by UTB_NonETRs. More specifically, the persistence of earnings appears to be higher for firm-years with large UTB_NonETRs. When comparing the relative power of UTB_NonETR with Cash-ETR, the results indicate that UTB_NonETR is incrementally useful for explaining the ranking orders of temporary book–tax differences. However, it appears that neither UTB_NonETR nor Cash-ETR is relatively more useful over another under the Vuong (1989) test.

First, the part of UTB, if recognized, that would not affect earnings (UTB_NonETR) is used as an empirical proxy and its usefulness is tested in the context of book–tax differences and the persistence of earnings. Second, new evidence is provided supporting the predictions, as in Ayers’ et al. (2010) and Blaylock et al.’s (2012) studies, that the level of tax planning will attenuate the negative association between large book–tax differences and earnings quality. Third, the findings can contribute to the post-implementation review of FIN48 (Financial Accounting Foundation, 2012) supporting the argument that FIN48 can provide decision-useful information for financial statement users.

The purpose of this paper is to test the economic theory that product market competition should enhance firm performance in the US corporate tax management setting. It identifies one mechanism through which corporate management can improve firm performance. The paper also identifies business conditions that may facility or impede effective corporate tax management.

The paper tests the relationship between product market competition and corporate tax efficiency using large archival data. The primary data source is COMPUSTAT, which contains annual and quarterly accounting data for US public firms. Other data sources include accounting comparability data generously shared by Professor Vedi.

The paper finds that firms in competitive industries are more efficient in managing taxes. Specifically, the paper documents that firms in competitive industries exhibit lower effective tax rates than their non-competitive counterparts. Furthermore, the paper finds that the positive link between competition and the efficiency of tax management is much stronger for firms with lower cash flow volatility and for firms with fewer industry investment opportunities. The lack of financial statement comparability may weaken this link.

Tax laws vary greatly from country to country. Readers should interpret the results within the US tax environments.

Results in this paper have implications for multinational corporations that are interested in investing and doing business in the USA.

This paper sheds light on how competition influences firm performance through efficient tax management, a specific mechanism through which competition improves firm performance. To the best of the author’s knowledge, this study provides the first documentation of how product market competition affects tax planning for US publicly traded companies.

This project requires students to analyze and make a client recommendation for the most tax-effective saving option, comparing a traditional individual retirement account (IRA) versus Roth IRA. Students analyze the two alternatives and track growth as well as projected tax liability over the life of the client to determine the strategy that generates the best outcome for the client. The project emphasizes principles of tax planning to illustrate that the solution with the smallest tax liability in the short term is not necessarily the most beneficial option over the long term, as well as how this often is in conflict with a client’s expectations and tax preparer tactics utilized to attract new clients. Students will demonstrate critical thinking skills through the analysis of two options for a client, and the communication of the findings with a recommendation through a client letter.

The purpose of this chapter is to serve as a resource for accounting faculty seeking tax-related cases to include in their courses. This annotated bibliography provides a table and discussion of 50 educational tax cases published in six major accounting journals from 2003 to 2021. Cases are classified and discussed by recommended course placement. In addition, the authors make observations about trends in case content and format. This chapter complements the Fogarty (2022) review and commentary on tax cases published in this volume.

The purpose of this research is to determine whether the type of tax services provided by a public accounting firm to its audit client and the consequence severity of an audit failure impact jurors' assessment of audit quality and auditor liability.

The authors administer a court case to 168 jurors manipulating three levels of tax services provided to an audit client (none, tax preparation, and aggressive tax planning services); two levels of consequence severity of the alleged audit failure, observing the impact on jurors' assessment of audit quality, auditor responsibility for audit failure; and damages awarded the plaintiff.

Consistent with recent US regulations, jurors perceive the quality of the audit to be lower when auditors provide aggressive tax planning services, but not for tax preparation services. Damages are greater when auditors provide aggressive tax planning services across both levels of consequence severity.

The results indicate that the type of tax services provided may impact jurors' views of audit quality and damage assessments against auditors. The questionnaire uses previously validated measures, but the results may not be generalizable to jurors in all jurisdictions.

Though empirical evidence is mixed at best about the impact of auditors providing non-audit services on auditor independence in fact, auditor independence in appearance, and thus audit quality, such impacts may affect the way jurors perceive the situation.

The study directly tests the implications for auditor liability of new restrictions on tax services and more accurately measures the impact of consequence severity, using actual jurors.

Against the background of increasing regulation and spotlight on the tax position of MNEs, this study explores the relationship between tax and performance measurement. The paper is informed by a series of in-depth semi-structured interviews conducted in 2006 with 26 senior tax executives from 15 Silicon Valley-based companies. We also draw on documentary evidence including the relevant 10K reports and take an interpretive approach to the analysis. Many of the performance measures referred to in prior literature were employed in the companies. There was no evidence to suggest the profit centre performance measurement model is being adopted by MNEs for their tax departments. Two distinct aspects particularly exercised the interviewees, that is, the effective tax rate (ETR) and post-tax versus pre-tax performance measurement. Many interviewees did not perceive the ETR as being an appropriate measure of performance, yet they recognised its importance internally and externally. Many companies worked on the basis that there is an ‘acceptable range’ of ETRs which won’t give rise to any unwanted questions. Most interviewees shared the view that a post-tax basis of measuring performance of business units might only serve to increase tax risks, preferring instead for the in-house tax executives to remain the exclusive tax knowledge experts. This study contributes to the diversification of tax research within accounting by demonstrating how qualitative work can provide unique insights. It enhances our understanding of how performance measurement of tax might influence the tax-planning behaviour of in-house tax executives and cautions against exclusive reliance on the ETR as a measure of the effect of tax planning.

This chapter presents a seven-part case developed for use in a graduate-level tax planning class. The case is organized in a taxpayer/business “life-cycle” approach. Over the semester the case follows a married couple as they consider a number of investments, start a business, and expand the business. As the case progresses, the couple faces increasingly complex tax and business issues. The couple eventually winds down their involvement in the business and begins to plan for their retirement years. This chapter also provides a review of behavioral tax research published in the top accounting journals over the period 2004–2013. The chapter concludes with a discussion of how the case could be adapted by behavioral tax researchers in their research programs and perhaps by accounting firms in their training programs.

The purpose of this study is to examine the interactive impact of tax avoidance and tax risk on the firm value.

This study covers 290 observations on non-financial corporations listed on the Tunisian Stock Exchange for the period ranging from 2008 to 2020, using the multiple linear regression technique.

The results show that tax avoidance positively affects the firm value while tax risk has a negative influence on the company value. More importantly, tax risk moderates the positive impact of tax avoidance on the firm value. Accordingly, tax avoidance must be considered in conjunction with tax risk when studying the effect on the firm value. The findings of additional analyses indicate that when tax avoidance is associated with a high level of tax risk, it negatively affects the firm value. Thus, investors negatively rate the high-risk tax avoidance.

The major limitation of this study is that it focuses only on Tunisian listed companies since their financial statements are publicly available. Although the sample is relatively small due to the problem of data availability, it is satisfactory owing to the twelve-year sampling period (from 2008 to 2020). Research implications- The results obtained are of great interest to researchers as they should be more careful in simply using effective tax rates as a measure of risky or aggressive tax avoidance.

The findings may signal the need for Tunisian firm managers to consider spillovers when adopting risky tax avoidance strategies and to implement a tax risk management policy within the firm. They are also substantial for Tunisian regulators to create requirements for reporting risky tax avoidance practices in the company annual reports to protect the investors’ rights and the society interest in general. The results are also useful for the investors who would like to make good decisions with respect to tax planning strategies. It is not enough to rely on the Effective Tax Rate (ETR) to judge whether or not tax planning is risky. Volatile ETRs, as a proxy of the tax risk, can be useful for them in decision-making.

The results also highlight that risky tax avoidance decreases the firm value, and thus confirm the negative repercussions that such behavior can have not only on the firm, but also on the society in general, as the corporate tax contributes to covering the State public expenditure. Hence, it is considered a general concern.

The present study differs from others in the existing literature. In fact, it examines the joint effect of tax avoidance and tax risk on the firm value for Tunisian listed companies which are characterized by the predominance of agency conflicts between major shareholders and minor ones. Therefore, the authors seek to investigate if small shareholders can penalize risky tax avoidance practices by decreasing the firm value.
