Indirect taxation and tax incidence under nonlinear pricing

This paper study how a change in specific and ad valorem taxes under nonlinear pricing affects tax incidence. We show that an increase in either tax rate leads to a higher usage fee for all consumers, whereas the fixed fee under reasonable assumptions will fall. Finally, the model shows that the presumption in favor of ad valorem taxes over specific taxes also holds under nonlinear pricing and incomplete market coverage.     

Analyzing the standard deduction as a presumptive tax

Presumptive taxes can be found in the tax system of most developing countries and make sense when the desired tax base is difficult to measure, verify, and monitor. As a substitute for the desired tax base, the presumed tax base is derived from items that can be more readily monitored. Presumed taxes can also be found in developed countries, and examples include fixed depreciation schedules in place of asset-specific measures of decline in asset value, floors on deductible expenses, and the standard deduction. The authors analyze presumptive income taxation with an ultimate goal to initiate an approach to optimal presumptive taxation. This paper begins that task by analyzing the standard deduction in the individual income tax system in the United States.     

Financial leverage and corporate taxation: evidence from German corporate tax return data

To estimate the impact of profit taxation on the financial leverage of corporations, this study uses a pseudopanel constructed from comprehensive corporate tax return microdata for the period 1998–2001, which saw the introduction of major corporate tax reform in Germany. Financial leverage refers to the ratio of long-term debt to total capital. The endogeneity of the firm-specific marginal after-financing corporate income tax rate is controlled for by an instrumental variable approach. The instrument for the observed marginal tax rate is the counterfactual tax rate that a corporation would have faced in a particular period had there been no endogenous change, triggered by the tax reform, of its financial leverage and tax base. This counterfactual tax rate is derived from a detailed microsimulation model of the corporate sector, based on tax return microdata. The marginal tax rate has a statistically significant and relatively large positive effect on corporate leverage; for firms reporting positive profits, an increase of the marginal tax rate of 1 % would increase the financial leverage by approximately 0.7 %, on average. The debt ratio is less responsive to tax incentives for small corporations and firms facing high economic risks.     

BAD taxation: Disintermediation and illiquidity in a bank account debits tax model

This paper uses a dynamic general equilibrium model to study the economic effects of bank account debits (BAD) taxation. Australia and various Latin American countries have levied or levy BAD taxes. Aspects such as financial disintermediation, market illiquidity, and impacts on dividend and interest rates are considered. Part of the BAD tax revenue may be fictitious, due to increased interest payments on government debt. The Brazilian BAD tax (CPMF) experience is evaluated. The empirical analysis confirms some theoretical predictions. Incidence base over GDP appears to be sensitive to the tax rate, possibly engendering a Laffer curve. The tax may also cause real interest rates to increase. Furthermore, the deadweight losses are relatively large, even if revenues are small. The theoretical and empirical results suggest that the BAD tax is not adequate for revenue collection. JEL Code E62 · H20     

Humpty Dumpty's guide to tax law: Rules,principles and certainty in taxation

Tax systems are, most commonly, rules-based. This gives the impression of techno-rationality in the interpretation of the numbers from which tax bills are derived. In fact, uncertainty and complexity in tax rules are seen as promoting tax avoidance behaviour, as avoiders exploit this complexity. Some authors have advocated that this can be combated by replacing rules-based tax legislation with principles-based legislation, giving tax authorities and the courts the power to interpret legislation purposively.This paper demonstrates by reference to a number of UK tax cases that rules-based legislation already embodies the hidden operation of state power as judges have considerable discretion in the interpretation of rules. The paper goes on to argue that principles-based legislation would further empower the state vis-à-vis the citizen. While this might be intuitively appealing to the vast majority of taxpayers not engaged in tax avoidance, it brings with it the hidden danger of a fundamental alteration of the balance of power between the state and all citizens, and should therefore be treated with caution.     

Shareholder taxation and aggregate dividend payout: Evidence from the tax reform act of 1986

The effect of shareholder taxation on corporate dividend policy is a major controversy in financial economics. The Tax Reform Act of 1986 eliminated the statutory tax disadvantage of dividends versus long-term capital gains for individual shareholders. Using aggregate time series data I find evidence that corporate dividend payout has become more generous in the period after tax reform.     

International tax arbitrage,financial parity conditions and preferential capital gains taxation

Using a finite-horizon general equilibrium model with uncertainty and money, we characterize situations where tax arbitrage opportunities may arise for international portfolio investors in an economy with heterogeneous capital income taxation when interest income and capital gains/losses are taxed differentially for some agents. We derive tax-modified uncovered interest parity conditions, Fisher conditions and forward prices similar to the no-tax ones, but augmented by tax-induced ‘risk-premium’ terms; covered interest parity and Fisher conditions remain unaffected by the introduction of capital income taxes as we bound tax-based arbitrage without restricting arbitrage per se.     

Federal tax competition and the efficiency consequences for local taxation of revenue equalization

Recent work has shown that a system of equalization grants can neutralize the efficiency loss caused by tax competition among lower-level governments. These models, however, ignore the vertical tax externalities that occur when the federal and lower-level governments levy taxes on the same base. This paper incorporates equalization grants into a standard capital tax competition model in which there are horizontal tax externalities between jurisdictions and vertical tax externalities between the levels of government. It is shown that, even in the presence of vertical tax externalities, an efficient level of lower-level government taxation can be achieved with a modifying version of a standard equalization grant formula.     

A welfare comparison of ad valorem and unit tax regimes

This paper strives to merge two strands of the literature. The first group of papers compares ad valorem and unit taxes in a tax competition framework in terms of welfare. The second group of papers regards capital income taxes as a conjunction of taxes on pure profits and taxes on capital income. We find that, given decreasing returns to scale, there always exists a level of the share of deductible capital costs strictly smaller than one, such that for all values larger than this threshold, an ad valorem tax regime unambiguously Pareto-dominates a unit tax regime.     

Taxpayers' responsiveness to tax rate changes and implications for the cost of taxation in Sweden

Historically, labor supply elasticities have been used to evaluate tax policy and predict tax revenue effects. They are likely to underestimate taxpayers' response to tax rate changes, and hence to underestimate changes in potential tax revenues, however, because they measure only how taxpayers alter hours worked. Taxpayers can also respond to tax rate changes by altering, for instance, their work effort and form of compensation. An alternative measure that accounts for these responses as well as hours worked is the elasticity of taxable income. This paper estimates the elasticity of earned taxable income for Swedish taxpayers using two different approaches and a number of control variables and the 1990/1991 tax reform as a “natural experiment”. The preferred elasticity estimates fall in the range of 0.4–0.5, comparable with recent estimates for the U.S. and larger than most of the labor supply elasticity estimates used to evaluate tax policy in Scandinavia previously, which suggests that deadweight losses are two to three times higher than previously thought.

Capital structure choice and company taxation: A meta-study

This paper provides a quantitative review of the empirical literature on the tax impact on corporate debt financing. Synthesizing the evidence from 48 previous studies, we find that this impact is substantial. In particular, the tax rate proxy determines the outcome of primary analyses. Measures like the simulated marginal tax rate (Graham, 1996) avoid a downward bias in estimates for the debt response to tax. Moreover, econometric specifications and the set of control-variables affect tax effects. Accounting for misspecification biases by means of meta-regressions, we predict a marginal tax effect on the debt ratio of about 0.27.     

Free trade taxation and protectionist taxation

The goal of this paper is to seek new insight regarding international tax policy by recasting it in parallel with the theory of international trade. This is accomplished by defining a free trade taxation regime as one that is consistent with an efficient worldwide allocation of capital, and evaluating within this perspective various aspects of tax policy, such as value-added (axes, integration, income shifting, and the choice of worldwide or territorial system of taxes.Compatibility with free trade is not the only standard against which to judge an international tax system. Nevertheless, as national economies become more integrated the importance of international taxation for the efficient functioning of capital markets will become a central policy issue.

Environmental taxation and the double dividend: A reader's guide

There has been considerable debate as to whether the revenue-neutral substitution of environmental taxes for ordinary income taxes might offer a double dividend: not only (1) improve the environment but also (2) reduce certain costs of the tax system. This paper articulates different notions of double dividend and examines the theoretical and empirical evidence for each. It also connects the double-dividend issue with principles of optimal environmental taxation in a second-best setting.A weak double-dividend claim-that returning tax revenues through cuts in distortionary taxes leads to cost savings relative to the case where revenues are returned lump sum-is easily defended on theoretical grounds and (thankfully) receives wide support from numerical simulations. The stronger versions contend that revenueneutral swaps of environmental taxes for ordinary distortionary taxes involve zero or negative gross costs. Theoretical analyses and numerical results tend to cast doubt on the strong double-dividend claim, although the theoretical case is not air-tight and the numerical evidence is mixed.     

Assessing professional ethics in tax: A case on uncertain tax positions

We develop and present an ethics case dealing with an uncertain tax position. The case can be used to assess professional ethics as part of an assurance-of-learning (AOL) plan as well as a component of a course grade. We present data on student performance on this case over a 5-year period. Students consider existing ethical frameworks to identify and frame the potential ethical “dilemmas” they might face in addressing whether to countenance a client’s suggested treatment and disclosure of an uncertain tax position. In addition, students evaluate the AICPA guidance and U.S. Treasury standards on taking and reporting uncertain tax positions in the tax return and the FASB and PCAOB standards on reporting and auditing uncertain tax positions in the financial statements. The case allows faculty to assess students’ ability to frame potential ethical dilemmas when clients engage in aggressive tax behavior, to recognize with whom and with what professional reference documents they should consult when an uncertain tax position arises, and to choose among alternative actions when faced with client/preparer conflicts.     

Gold and tax capitalization: A natural experiment

This research examines whether U.S. income taxes are capitalized into gold coin prices. For years, the American Eagle (Eagle) was the sole gold coin to be IRA eligible. The Taxpayer Relief Act of 1997 expanded eligibility to include all other gold coins beginning on January 1, 1998, except the South African Krugerrand (Rand). In this natural quasi-experiment, we examine whether gold coin prices reacted to the change in IRA-eligibility. Results are largely consistent with the capitalization of implicit taxes in gold coin prices. When legislation allowing IRA eligibility of both the Canadian Maple Leaf (Maple) and the Rand was introduced, the prices of both coins increased relative to the Eagle. When final legislation excluded the Rand from IRA eligibility, but not the Maple, the Rand's price declined while the Maple's did not. The findings contribute to the tax capitalization literature and the effects of interjurisdictional taxation in integrated global markets.

Boundary work and tax regulation: A Bourdieusian view

Boundaries are ubiquitous in modern social life, and the work of creating and maintaining boundaries is particularly evident within regulatory fields. Through the analysis of a recent critical incident in the tax field (Arctic Systems) with which the accounting profession is intimately associated, this paper uses a Bourdieusian lens to unravel the relational complexities of the regulation of tax avoidance at the complex and fuzzy boundary between acceptable and unacceptable tax practice. We develop an alternative, relational interpretation of tax regulation and contribute to a more nuanced understanding of regulatory practice within the tax field that also raises questions about regulatory practice more widely. We conclude by highlighting how a move towards ‘relational’ regulation might contribute to improved understanding of regulatory processes and practices.     

Mapping tax compliance: Assemblages,distributed action and practices: A new way of doing tax research

Tax compliance denotes the act of reporting and paying taxes in accordance with the tax laws. Current social science scholarship on tax compliance can almost entirely be divided into behavioural psychology analyses and critical tax studies. This article, which presents two cases of how tax compliance is constructed, challenges the explanatory reaches of today's social science approaches, arguing that an alternative approach to understanding tax compliance is worthwhile exploring. This other choice of approach, inspired by actor–network theory (ANT), adopts a more practice-oriented focus that studies tax compliance where it takes place as well as what it is made of. Consequently, this article argues that tax compliance is a socio-material assemblage and that complying is a distributed action. The article concludes by highlighting how an ANT approach contributes to the further theoretical development of social science studies of taxation.
