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.     

Tax avoidance and ex ante cost of capital

This study examines the association between tax avoidance and ex ante cost of equity capital. Based on prior research, we develop two proxies for investors’ expectations of tax avoidance and explore whether deviations from those expectations result in higher ex ante cost of equity capital. We find that the ex ante cost of equity capital increases with tax avoidance that is either below or above investor expectations and that the increase is larger for tax avoidance that exceeds investors’ expectations. We then examine whether firms that alter their future tax avoidance exhibit a lowering of their ex ante cost of equity capital and find that tax avoidance decreases (increases) from the prior year for firms that were above (below) investors’ expectations in the prior year. These results are consistent with the trade‐off suggested by the Scholes and Wolfson framework and reinforce the notion that balancing tax benefits and non‐tax costs is an important feature of firms’ tax planning.     

Market's perception of deferred tax accruals

This study investigates the value relevance and incremental information content of deferred tax accruals reported under the ‘income statement method’ (AASB 1020 Accounting for Income Taxes) over the period 2001–2004. Our findings suggest that deferred tax accruals are viewed as assets and liabilities. We document a positive relation between recognized deferred tax assets and firm value using the levels model, while the results from the returns model suggest that deferred tax liabilities reflect future tax payments. The balance of unrecognized deferred tax assets provides a negative signal to the market about future profitability, particularly for companies from the materials and energy sectors and loss‐makers.     

Taxpayers' Behavioural Responses and Measures of Tax Compliance ‘Gaps’: A Critique and a New Measure

The work of Feldstein (1995 and 1999) has stimulated substantial conceptual and empirical advances in economists' approaches to analysing taxpayers' behavioural responses to changes in tax rates. Meanwhile, a largely independent literature proposing and applying alternative measures of tax compliance has also developed in recent years, which has sought to provide tax agencies with tools to identify the extent of tax non‐compliance as a first step to designing policies to improve compliance. In this context, measures of ‘tax gaps’ – the difference between actual tax collected and the potential tax collection under full compliance with the tax code – have become the primary measures of tax non‐compliance via (legal) avoidance and/or (illegal) evasion. In this paper, we argue that the tax gap as conventionally defined is conceptually flawed because it fails to incorporate behavioural responses by taxpayers. We show that conventional tax gap measures, which ignore the presence of behavioural responses, exaggerate the degree of non‐compliance. This potentially applies both to indirect taxes (such as the ‘VAT gap’) and direct (income) taxes. Further, where these conventional tax gap measures motivate reforms designed to increase the tax compliance rate, they will likely have a tax‐base‐reducing effect and hence generate a smaller increase in realised tax revenues than would be anticipated from the tax gap estimate.     

Determinants of tax haven utilization: evidence from Australian firms

This paper examines the major determinants of tax haven utilization based on a sample of 200 publicly listed Australian firms, over the 2006–2010 period (1,000 firm‐years). Our regression results show that variables relating to transfer pricing, intangible assets, an interaction term between transfer pricing and intangible assets, withholding taxes, performance‐based management remuneration and multinationality are positively associated with tax haven utilization. We also find that corporate governance structures are negatively associated with tax haven utilization. The magnitude and significance of the regression coefficients indicate that transfer pricing, withholding taxes, intangible assets, an interaction term between transfer pricing and intangible assets, corporate governance and multinationality are the most important drivers of tax haven utilization.     

Attitudes towards Tax Levels: A Multi‐Tax Comparison*

We analyse Swedes' opinions about the levels of 11 different taxes to see which taxes people are most averse to and why. The most unpopular tax is the real estate tax, while the corporate tax is the least unpopular. We find a strong self‐interest effect in tax attitudes and that knowledge and education increase support for corrective taxes.     

Response of Tax Credit Claims to Tax Enforcement: Evidence from a Quasi‐Experiment in Chile

Diesel in Chile receives different tax treatments depending on its use. If diesel is used in industrial activities, the diesel taxes paid can be fully used as a credit against VAT, but if it is used in freight or public transportation – basically trucks and buses – only a fraction of diesel taxes paid can be claimed as a tax credit for VAT payments. As a result of this different tax treatment, firms have incentives to use ‘tax‐exempted’ diesel in activities requiring ‘non‐tax‐exempted’ diesel. This tax wedge therefore generates an opportunity for tax evasion, especially for firms with multiple economic activities, one of them being transport. In this paper, we analyse the impact of a tax enforcement programme implemented by the Chilean Internal Revenue Service (IRS), where letters requiring information about diesel purchases and use and vehicle ownership were sent to around 200 firms in 2003. Using different empirical strategies to consider the non‐randomness of the selection of firms, the empirical results show consistently that firms receiving a letter decreased their diesel tax credits by around 10 per cent.     

Simplifying the personal income tax system: lessons from the 1998 Spanish reform

Governments often try to reduce the complexity of personal income tax systems by decreasing the number of tax filings. The 1998 reform of the Spanish income tax system has followed this approach by adjusting withholding on earned income to the income tax liability. In this paper, we assess to what extent the reform has fulfilled its purposes, making use of a micro‐simulation tax‐benefit model for Spain, ESPASIM. The number of individuals exempt from filing a tax return has been reduced to around half of the total number of taxpayers. However, the quantity of tax returns sent to the tax administration has not changed so much because the new withholding system adjusts taxes for only 29 per cent of those exempt. Moreover, the new system increases the overall excess of tax withholding by 1.5 billion euro. We also study alternative reforms that could achieve better results than the one implemented.     

A hybrid consumption-based direct tax proposed for Bolivia

In 1994 the authors designed a consumption-based direct tax for the government of Bolivia. The proposal combined yield exemption treatment (exemption of interest income and no deduction for interest expense) of individuals with consumed income tax treatment (taxation or deduction of the net proceeds of borrowing and lending, as well as interest income and expense) of business. This article explains why taxation based on cash flow has administrative and economic advantages over a conventional income tax and why the hybrid system proposed is preferable to either pure form of consumption-based tax.     

税率调整:强化我国个人所得税收入分配调节效应的选择

个人所得税在调节收入分配上具有其他税种无法相比的优势。在我国,其收入分配调节功能却未充分发挥,甚至在一些年份出现逆调节现象。本文通过分析我国个人所得税收入分配逆调节效应的原因,认为:课税模式、费用扣除标准和税率都对个人所得税收入分配调节作用产生影响。但通过对这三者的分析,认为个人所得税税率的调整才是强化个税收入分配调节功能的重心。     

The composite dividend tax rate

Dividends often impose taxes on investors. However, as certain prior financial models indicate, they also can produce a tax gain from leverage. Hence the composite marginal dividend tax rate can be specified as the nominal rate minus the offsetting tax gain from leverage. Although this principle has been embedded in theoretical models for more than 40 years, no prior study has examined empirically whether the dividend-induced tax gain from leverage influences dividend policy. We address this empirical void and find dividends decrease in the nominal dividend tax rate and increase in the offsetting tax gain from leverage. In addition, we find the composite tax rate outperforms traditional measures in explaining dividend policy for our full sample of firms. Consistent with prior theory, we also find the composite rate varies in influence according to the financing source for a dividend.     

The Market Response to Beating After‐tax Earnings Targets Revisited using Analysts’ Pre‐tax Earnings Forecasts and Concurrent Tax Note Disclosures

We investigate whether the premium for achieving after‐tax earnings targets is informed by the availability of pre‐tax and after‐tax earnings forecasts. We find evidence the premium is discounted for firms achieving only after‐tax earnings forecasts compared with firms achieving both forecast targets. This is likely due to the uncertainty about future profitability and earnings quality created by failing to attain pre‐tax earnings targets. For firms achieving only pre‐tax earnings forecasts, no premium is documented. Taken together, our results indicate that while pre‐tax earnings forecasts may not move the market, they have an informational role in providing a context for assessing the achievement of after‐tax earnings targets. We also consider the usefulness of the tax note disclosures of deferred tax assets from carry‐forward losses for assessing the premium for achieving after‐tax earnings targets. Reflecting the duality of this tax deferral, we find evidence that recognition of these tax assets conveys information about lower earnings quality when recognition is likely to be opportunistic (in the case of firms achieving only after‐tax forecasts), and provides a signal of future profitability (in the case of firms achieving only pre‐tax forecasts).     

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     

Corporate domicile and average effective tax rates: The cases of Canada,Japan, the United Kingdom,and the United States

We use financial statement information to estimate three alterantive average effective tax rates for firms domiciled in Canada, Japan, the United Kingdom, and the United States during the period 1982 to 1991. While many of the firms we examine operate worldwide, we use the termdomicile to refer to the legal residence or site of incorporation of the parent company. Our objective is to determine themarginal impact of a company's domicile on its worldwide tax burden, with controls for industry and year. We find both among domestic-only companies and among multinational companies the domiciles are consistently ranked in descending order by average effective tax rates as Japan, the United Kingdom, the United States, and Canada. In comparing domestic-only companies and multinationals domiciled in the same jurisdiction, only U.S. multinationals consistently face a greater tax burden than their domestic counterparts.     

Do Personal Taxes Destroy Tax Shields? A Critique to Miller’s (1977) Proposal

We discuss the relevance of personal taxes on tax shields. Interest and taxes are the basis for defining an optimal capital structure. When personal taxes are greater than or equal to TS, an optimal capital structure does not exist.

We suggest that the approach proposed by Miller (1977) might understate the effect of personal taxes in the net TS and/or its associated net value. We consider the irrelevance of personal taxes on interest received by debtholders on the value of TS earned by the firm on interest paid. We conclude that Miller’s approach might be wrong and has some inconsistencies.     

Tax-tariff reform with costs of tax administration

As is broadly recognised, the straightforward application of the Diamond–Mirrlees (1971) production efficiency theorem implies that when lump-sum taxation is not available, then it is optimal for the government in a small open economy to rely on taxes on the net demand of households rather than on border taxes to finance its resource requirements. However, the theorem does not hold when taxation is associated with administrative costs. The present paper explores the implications for optimal taxation and for desirable directions of tax-tariff reform of taking into account the costs of tax administration in countries at different levels of economic development. The paper clarifies the reasons for, and lends support to, the criticism by Stiglitz (Presentation to Congress of International Institute of Public Finance, Prague, 2003) of the IMF and the World Bank’s recommendation to developing countries to adopt VAT to replace border taxes.      

Value-added tax options for India

The pressures of aggregate revenue, the requirement of a reduced role for customs duties for the liberalization of the economy, and the complexity and strains of the current system together point clearly toward the desirability of tax reform in India. Since domestic indirect taxes provide the major source of revenue, they deserve special attention. This paper argues that India would benefit from moving toward a system of value-added taxation (VAT) and focuses on the way in which a VAT (or VATs) can be best introduced into India given the country's federal structure. Three different options are distinguished: a central VAT, dual VAT, and states' VAT. We argue that the first is politically infeasible, that the second represents the best way forward in the short term, and that the third deserves consideration as a long-run option. Special attention is paid to the problems that would arise under either a states' or a dual VAT with regard to taxing interstate trade.     

The origin principle and the welfare gains from indirect tax harmonization

This paper establishes a parallelism between indirect tax harmonization when taxes are levied according to the destination principle and its counterpart when taxes are imposed on an origin basis. Using a simple two-country model of international trade it is argued that, under normal circumstances, indirect tax harmonization under the origin principle, considered as a movement of domestic taxes toward an appropriately designed average tax structure, is potentially Pareto improving. It is also shown that if the initial position is a Nash equilibrium, there are exceptional situations under which the above-mentioned reform may generate an actual Pareto improvement, so that both countries improve their welfare without any need for a compensating international transfer.     

Globalisation,taxation and inequality

Today's tax systems, in which value-added taxes and payroll taxes play a prominent role, are largely creations of the 1950s. We need to invent modern tax systems adapted to the reality of the 21^st century: the growing importance of capital and the rise of inequality. This article reviews some of the challenges involved with increasing the progressivity of tax systems in a globalised world and discusses how these challenges could be overcome. I make the case for new and more ambitious forms of international cooperation and for modern forms of wealth taxation.     

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.
