Organizing tax instruction: Evidence regarding how students organize tax knowledge

An important part of accounting curriculum reform is a movement away from traditional methods of organizing accounting courses toward improved organization schemes. Two basic approaches to organizing the content of tax courses are a transaction-based scheme and an entity-based scheme. This paper reports the results of an experiment that investigates which scheme is more consistent with how incoming masters in tax students organize tax knowledge and how different schemes affect the manner in which graduating students organize tax knowledge. Ninety students drawn from two full-time masters in taxation programs participated in the study. Subjects individually completed three separate tasks that measured how they organize tax knowledge at both the start of their degree program and three semesters later at or near the end of their program. The results for all three tasks indicate that incoming tax students organize tax knowledge around the type of transaction involved. The results for two of the three tasks indicate that the students' transaction focus did not change during their graduate tax program, whereas the results for the third task indicate that the students' transaction focus increased during their graduate tax experience. The implications of these findings for improving tax instruction are discussed.     

Limits of tax regulation: Evidence from strategic R&D classification and the R&D tax credit

We investigate a tax avoidance strategy where firms use the ambiguity inherent in tax reporting to classify indirect costs as research and development (R&D) expenditures to take advantage of the R&D tax credit. We label this tax practice “strategic R&D classification”. We find a one standard deviation increase in strategic R&D classification leads, on average, to a 1.7% (1.5%) reduction in GAAP (cash) effective tax rates, suggesting this practice provides significant tax savings. However, we also find strategic R&D classification is related to both the level and changes in uncertain tax benefit liabilities required to be recognized under FIN 48, suggesting this practice comes with financial reporting costs. Our study contributes to the literature by documenting some of the costs and benefits associated with a previously unexplored tax strategy, and highlights the limitations faced by tax authorities in monitoring firms’ R&D tax credit.     

Corporate tax avoidance: is tax transparency the solution?

Corporate tax avoidance has been a matter of considerable public attention, particularly since the 2008 global financial crisis. The nature of calls for tax reform and increased regulation, advocated most prominently by tax activists and NGOs, has revolved around transparency as a possible corrective to unacceptable tax avoidance, although there is no consensus as to what the term tax avoidance encompasses and when it becomes unacceptable. We examine two responses to calls for increased transparency about the tax affairs of multinational entities: firstly, country by country reporting that provides information to tax authorities, and secondly the UK requirement for publication of tax strategies, whereby large companies put information into the public domain. We find considerable misunderstanding about the benefits of transparency in this setting. By failing to consider the limits of transparency initiatives there is a risk of dysfunctional consequences, for example additional costs in providing and processing additional information, the prospect of increased disputes as new information generates new misinterpretations and uncertainty in determining the final tax position. There is a risk that greater disclosure will not effectively address concerns about unacceptable corporate tax avoidance.     

Valuation of tax expense

As tax expense reflects value lost to taxes paid, it should be negatively associated with value, provided nontax, value-relevant information is controlled for. However, valuation regressions estimated in prior research—using contemporaneous tax expense and nontax variables—document substantial variation in the coefficients on tax expense, ranging from significant negative to significant positive values. We show this variation is (a) caused by the omission of expected future profitability, and (b) explained by many factors that cause variation in the correlations among included variables and omitted future profitability. Unfortunately, difficulties associated with separating the impact of individual factors hampers tax research investigating determinants of the value relevance of tax expense.     

Single-case technique for teaching the tax research process

This article describes an instructional technique using a single current tax case to demonstrate the many facets of tax research methodology. The technique is just one resource used for teaching the graduate tax research course, and provides for a richer contextual environment in which to learn the tax research process. Using a single case based on actual events, the many sources of statutory and judicial tax authority were incrementally evaluated to solve the tax problem, and integrally analysed for the final conclusions. In addition, the case centred on a very public and political tax issue, which generated increased interest among students and illustrated the political process associated with tax law development. Application of the technique for desired learning outcomes and assessment objectives are also discussed.     

Interactive learning through the use of student federal tax clinics

With approval from the Internal Revenue Service (IRS), student federal tax clinics may be operated by law schools or graduate accounting programs. Currently there are 17 student federal tax clinics approved by the IRS. The graduate accounting program at the University of North Texas (UNT) was the first graduate accounting program permitted to operate a clinic and is currently one of only three accounting programs in the nation that operate a clinic. The program allows graduate accounting students to represent taxpayers before the IRS at the audit and appeals conference. This article demonstrates how tax clinics provide an excellent means for interactive learning while helping students and professors keep abreast of practice issues. Information on establishing and operating an accounting student tax clinic is provided as well as a list of current tax clinic participants.     

The role of political elites in income tax system design and tax fairness

Given the importance of fairness in the public acceptance of tax systems (Mirrlees et al., 2011), understanding the role of political elites in the tax design process and how this impacts fairness is important. In this paper, we use an interpretative approach to examine the design and ultimate rejection of the Kansas tax policy experiment that ran from May 2012 to June 2017. The central design element of this experiment was the fundamental disruption of the long-standing principle of horizontal equity (fairness), in which non-wage business income was relieved of income tax, while wage income was taxed. By interpreting this experiment through a Bourdieusian lens, we identify five key themes that are helpful in understanding income tax design, tax fairness, and the role played by political elites. Overall, we contribute to the literature by highlighting the way in which cultural capital may be used by political elites to reformulate groups of taxpayers in order to justify unequal treatment of equal taxpayers, which represents a violation of the notion of horizontal equity (fairness). We also highlight that although such violations of fairness in income tax system design may be sustainable in the short run, over the longer term, notions of fairness are so deeply embedded in the habitus of individual taxpayers that a return to the status quo is likely.     

Graphical organizers in tax education

The purpose of this teaching note is to share with tax instructors several graphical organizers developed by the authors for use in teaching topics typically covered in undergraduate and graduate tax courses. Their use may be motivated by studies documenting improvements in student learning through improved text comprehension and memory when such displays are used, and also by studies concluding that students exhibit decreasing reliance upon textbook information and increasing reliance upon instructor provided communications in their learning and study processes. Additional motivation stems from the graphical organizers’ desirable attributes as instructional resources: ease of use, presentation efficiency and flexibility, and a facilitated ability to highlight cause-and-effect based conclusions inherent in tax law.     

Innovation quality of firms with the research and development tax credit

This paper examines innovation quality of U.S. research tax credit users (i.e., firms with currently earned research tax credits). Prior literature reports that the research tax credit is effective in increasing research and development (R&D) expenditures and reducing managers’ myopic behavior. However, little is known about the real (or economic) effect of R&D tax credits, as most of these findings have been based on estimated R&D tax credits rather than actual R&D tax credits. Additionally, some researchers and the government still have concerns about the real effect of R&D tax credits by criticizing the ambiguity and complexity of the tax codes (IRC Section 41). Therefore, I use actual R&D tax credits identified in firms’ 10-K and state R&D tax credits as identification tests to reduce endogeneity issues. My results indicate that research generating R&D tax credits contributes to better innovation quality and higher return volatility but lower pre-tax profitability. Overall, these findings imply that enacting the R&D tax credit provisions would trigger better innovation.     

Measuring income tax accrual quality

We develop and validate a measure of tax accrual quality. Tax accrual quality captures variation in the extent to which the income tax accrual maps into income tax-related cash flows, with lower variation indicating a higher quality tax accrual. Low tax accrual quality arises from (1) management estimation error and (2) financial reporting standards that lead to differences between income tax expense and income tax cash flows not captured by deferred tax assets and liabilities. We validate our tax accrual quality measure by showing it is associated with firm characteristics that capture both constructs and by demonstrating it predicts future tax-related restatements and internal control material weaknesses. We illustrate the importance of our measure by showing that investors view tax expense as more informative in firms with better tax accrual quality. Future researchers can use tax accrual quality to address questions related to estimation error in the income tax account.     

Corporate tax policy and incorporation in the EU

In Europe, declining corporate tax rates have come along with rising tax-to-GDP ratios. This paper explores to what extent income shifting from the personal to the corporate tax base can explain these diverging developments. We exploit a panel of European data on legal form of business to analyze income shifting via incorporation. The results suggest that the effect is significant and large. It implies that the revenue effects of lower corporate tax rates—possibly induced by tax competition—will partly show up in lower personal tax revenues rather than lower corporate tax revenues. Simulations suggest that between 12% and 21% of corporate tax revenue can be attributed to income shifting. Income shifting is found to have raised the corporate tax-to-GDP ratio by some 0.25% points since the early 1990s. This research was carried out while Ruud de Mooij was a visiting fellow at DG ECFIN in October 2006. The views expressed in this Article are those of the authors and do not necessarily reflect the official position of the European Commission.     

Empirical tax research in accounting

This paper traces the development of archival, microeconomic-based, empirical income tax research in accounting over the last 15 years. The paper details three major areas of research: (i) the coordination of tax and non-tax factors, (ii) the effects of taxes on asset prices, and (iii) the taxation of multijurisdictional (international and interstate) commerce. Methodological concerns of particular interest to this field also are discussed. The paper concludes with a discussion of possible directions for future research.     

The classical tax system,imputation tax and capital budgeting

Differences in the taxation systems in Britain, France, and some other European countries (which use the imputation system) compared with the USA and the Netherlands, among others (which use the classical tax system), mean that the cost of equity capital should be specified, using a capital asset pricing model methodology, in different ways. Under the imputation system its value should be net of personal taxes; under the classical tax system, it should be gross of personal taxes. Similarly the value of the tax shield on debt for input into adjusted present value calculations differs, being significantly greater under the classical tax system. Formulae are set out to enable the calculation of the magnitude of the tax shield readily to be undertaken.     

Structuring a tax efficient international operation

International taxation is rapidly increasing in importance in the U.S. business environment. As a student preparing for a career in public accounting or industry, it is vital that you have familiarity with key international tax issues. In this case, you will participate in a detailed tax-planning exercise involving a multinational corporation that is restructuring its tax operations. In the process, you will be exposed to a wide-ranging array of real-world tax issues: tax theory, source of income, transfer pricing, foreign tax credits, the foreign earned income exclusion and Subpart F income. The case also incorporates questions designed to help you explore the financial accounting implications of tax planning. The case consists of three tax modules and each module emphasizes two to three specific tax issues. Two of the modules also contain a subset of tax-related financial accounting questions. To complete the case successfully, you will be required to understand basic international tax theory, to engage in the tax research process and to apply your theoretical knowledge in analyzing complex business scenarios.     

Do tax incentives affect investment quality?

This paper examines the effect of tax incentives in the form of bonus depreciation on investment quality. Using the expiration of tax incentives via bonus depreciation in eastern Germany and a representative panel of West German establishments, we show that bonus depreciation significantly lowers investment quality. The average quality of investments, measured by the responsiveness of future revenue and other proxies for cash flow to current investment, reduces by 15.2–23.8% in the short run and 31.8–41.4% in the long run. Our research suggests that this adverse effect of tax subsidies is greater for jurisdictions with higher tax rates, in times of high unemployment, and for large or low-productivity establishments. Overall, while increasing investment quantity, as shown by prior literature, tax incentives such as bonus depreciation substantially reduce the quality of investments.     

Does tax avoidance increase or decrease when tax enforcement is stronger? Evidence using CSR heterogeneity perspective

Prior literature has reported mixed results on whether corporate social responsibility (CSR) activities are associated with more or less tax avoidance. These past results may be attributed to a failure to control for endogeneity between tax avoidance and CSR. We utilize an exogenous increase in tax enforcement to investigate how a heightened level of scrutiny by authorities affects tax avoidance by firms adopting CSR policies (CSR firms) compared to non-CSR firms. If stronger enforcement leads to greater tax compliance, we expect to observe a decline in tax avoidance measures in all firms. As expected, tax avoidance has decreased in non-CSR firms in response to this exogenous change, but surprisingly, in CSR firms it has increased. The results are supported by theories such as the licensing effect and organized hypocrisy. We contribute to the literature by using an exogenous shock to tax enforcement to shed light on whether CSR firms act in a socially responsible manner in their tax reporting. Moreover, we provide new empirical evidence relevant to the theory of organized hypocrisy, whereby there are notable inconsistencies between the actions that corporations take to bolster their public image and self-serving practices.     

Audit quality effects of the PCAOB's 2006 tax service restrictions

In 2004 and 2005, use of aggressive tax services provided by a company's auditor had become so broadly concerning that it was the focus of a PCAOB roundtable and discussed in a Congressional subcommittee investigation report (PCAOB, 2004 and US Senate, 2005). Although auditor provision of these and other nonaudit services to issuer audit clients was restricted in 2006, research on the effectiveness of these restrictions finds that they did not impact audit quality (Notbohm, Paterson and Valencia, 2015 and Lennox, 2016). We reexamine this issue with a focus on the audit quality effects for the engagements most impacted by the restrictions-Big 4 audit clients with pre-restriction tax service fees of at least $100,000 that fell by at least 75% following the restrictions. Using a difference-in-difference framework and two proxies for audit quality, we find evidence of the effectiveness of the PCAOB's 2006 restrictions among those clients. Additionally, we find these results are sensitive to the level of pre-restriction tax service fees, with the restatement (going concern) effect of the restrictions strengthening (weakening) in the pre-restriction tax service fee level. We also find that the effects of these restrictions are concentrated among clients of Big 4 auditors rather than clients of the 2nd tier or 3rd tier auditors. Results of additional analyses indicate that audit quality, as measured by the probability of restatement, was lower in the pre-restriction period for purchasers than for non-purchasers. Our results are robust to a barrage of sensitivity tests. Our findings contribute to the continued regulator discussion about the proper level and types of allowable tax nonaudit services.     

The incentives for tax planning

We use a proprietary data set with detailed executive compensation information to examine the relationship between the incentives of the tax director and GAAP and cash effective tax rates, the book-tax gap, and measures of tax aggressiveness. We find that the incentive compensation of the tax director exhibits a strong negative relationship with the GAAP effective tax rate, but little relationship with the other tax attributes. We interpret these results as indicating that tax directors are provided with incentives to reduce the level of tax expense reported in the financial statements.     

Benchmarks,characteristics and trends of U.S. graduate tax programs awarding a Master of Science in Taxation (MST) degree

Survey data gathered from graduate tax program directors at 26 universities, a response rate of about 43% of all programs contacted, is used to benchmark characteristics and trends of U.S. programs awarding a Master of Science in Taxation (MST) degree. The impetus for this paper was the absence of current literature regarding curriculum, enrollment, and delivery of graduate tax programs in the United States, and it is the first study to compile information on MST program trends.
