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.     

Banks as Tax Planning Intermediaries

We provide the first large‐scale empirical evidence of banks functioning as tax planning intermediaries. We posit that some banks specialize in assisting corporate clients with tax planning. In this role, banks make use of their centrality in financial relationships; access to private information; and ability to structure, execute, and participate in tax planning transactions for clients. We measure bank‐client relationships using loan contracts and measure client tax planning using either the cash effective tax rate or the unrecognized tax benefit balance. Using a difference‐in‐differences design, we find that firms experience meaningful tax reductions when they begin a relationship with a bank whose existing clients engage in above‐median tax planning. The effects of pairing with such tax intermediary banks are concentrated in relationships with larger or longer maturity loans, clients with foreign income or greater credit risk, and when the bank is an industry specialist or has above‐median investment banking activities. Finally, we find that potential clients are more likely to choose tax intermediary banks than nontax intermediary banks, suggesting that tax intermediary banks benefit by attracting new business. Collectively, our results suggest that some banks act as tax planning intermediaries, a role beyond the traditional one of financial intermediary.     

Corporate Social Responsibility,Tax Aggressiveness,and Firm Market Value

This paper examines the relationship of corporate social responsibility (CSR), tax aggressiveness, and firm market value. An economic model has been developed to show that profit‐maximization firms are willing to incur additional costs in CSR, such as paying more taxes, as long as they can differentiate their products from non‐CSR firms, and that socially conscious consumers will buy products from CSR firms at prices higher than those of non‐CSR firms. The empirical study in this paper indicates that the higher the CSR ranking of a firm, the less likely a firm is to engage in tax aggressiveness. It also indicates that a reputation of higher CSR will enhance firm market value. Using Canadian companies listed in the S&P/TSX 60 index, I find that both firms’ five‐year effective tax rates and annual effective tax rates are positively associated with their overall CSR scores as well as with their social scores. Firms’ five‐year effective tax rates are also positively associated with their governance index. I also find that firms’ overall CSR ranking and governance scores are positively associated with their market value.     

Anticipating Tax Changes: Evidence from the Finnish Corporate Income Tax Reform of 2005*

Using register‐based panel data covering all Finnish firms from 1999 to 2004, we examine how corporations anticipated the 2005 dividend tax increase via changes in their dividend and investment policies. The Finnish capital and corporate income tax reform of 2005 creates a useful opportunity to measure this behaviour, since it involves exogenous variation in the tax treatment of different types of firms. The estimation results reveal that those firms that anticipated a dividend tax hike increased their dividend payouts in a statistically significant way. This increase was not accompanied by a reduction in investment activities, but rather was associated with increased indebtedness in non‐listed firms. The results also suggest that the timing of dividend distributions probably offsets much of the potential for increased dividend tax revenue following the reform.     

The Informativeness of Dividends and Associated Tax Credits

This paper investigates the informativeness of dividends and the associated tax credits with respect to earnings persistence. After confirming that dividend‐paying firms have more persistent earnings than non‐dividend‐paying firms, we show that the taxation status of the dividend is also important. Firms that pay dividends with a full tax credit attached have significantly more persistent earnings than firms that pay dividends which carry no associated tax credit. Consistent with higher levels of tax credits identifying more mature firms, those paying dividends with full tax credits have significantly less persistent losses than firms that pay dividends with only partial tax credits. Further, market pricing tests confirm that the incremental information in dividends and tax credits contributes to reductions in market mispricing of the persistence of earnings and earnings components. Our results are robust to alternative model specifications and controlling for dividend size and firm age.     

Income Shifting in the Spanish Dual Income Tax*

Based on a model of behavioural response to taxes, and using the Taxpayers Panel from the Instituto de Estudios Fiscales for the period 1999–2009, we analyse whether the dual nature of the Spanish personal income tax (PIT), reinforced by the 2007 reform, has influenced taxpayers’ behaviour, causing them to convert part of their ‘general income’ (from labour, real estate or economic activities) into ‘savings income’ (from movable capital or capital gains). We also extend the analysis of income shifting and study whether Spanish taxpayers also responded to the different tax treatments given to the two types of savings income (from movable capital and capital gains) until 2007, transforming savings income from one type to the other. The results of our study demonstrate three facts. First, Spanish taxpayers did respond to the different tax rates, shifting income from the general base to different forms of savings, especially capital gains. The highest‐income individuals and the self‐employed and business owners are the groups where this behaviour was most marked. Second, the self‐employed and business owners also turned income from movable assets into capital gains, guided by their different tax rates. And third, we find signs of ‘anticipation’ and ‘learning’ effects caused by the 2007 tax reform. We believe that the results obtained will enrich the growing literature on income shifting.     

What is the After‐Tax Price of R&D? An Interstate Comparison*

As of 2005, 31 US states offered corporate income tax credits on research and development (R&D) expenses in order to encourage more in‐state innovation activities. Empirical questions about the efficacy of such tax breaks at the state level persist, in part because the complexity of the tax laws means that simple credit‐rate comparisons across states do not fully capture the differential variation in effective after‐tax price incentives firms face in choosing where to locate R&D activities. We are unaware of any research analysing and comparing the effective prices of R&D faced by firms, across all US states and utilising micro‐level data. Using data extracted from detailed reading of individual firms' 10‐K and S‐1 filings and of state‐level tax credit rules, we estimate the effective after‐tax price of basic and qualified research expenditure each firm would have faced in each of the 50 states had they been located there. Our methodology simulates the effective tax price of each firm's marginal dollar of research expenditure, assuming the firm chose to move all of its R&D operations to each of the 49 other states. Through Monte Carlo techniques, we consider the sensitivity of our interstate comparative results to several modelling assumptions. We find significant variation in after‐tax R&D prices across states with quite different R&D tax laws. Prices range from $0.176 to $0.520 on a marginal dollar of R&D in Virginia and Washington State, respectively. We also find that the interstate variability is generally more important – indeed, much wider than we had anticipated before investigating state‐by‐state regulations – than the inter‐firm variability within states.     

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.     

Public Pressure and Corporate Tax Behavior

We use a shock to the public scrutiny of firm subsidiary locations to investigate whether that scrutiny leads to changes in firms’ disclosure and corporate tax avoidance behavior. ActionAid International, a nonprofit activist group, levied public pressure on noncompliant U.K. firms in the FTSE 100 to comply with a rule requiring U.K. firms to disclose the location of all of their subsidiaries. We use this setting to examine whether the public pressure led scrutinized firms to increase their subsidiary disclosure, decrease tax avoidance, and reduce the use of subsidiaries in tax haven countries compared to other firms in the FTSE 100 not affected by the public pressure. The evidence suggests that the public scrutiny sufficiently changed the costs and benefits of tax avoidance such that tax expense increased for scrutinized firms. The results suggest that public pressure from outside activist groups can exert a significant influence on the behavior of large, publicly traded firms. Our findings extend prior research that has had little success documenting an empirical relation between public scrutiny of tax avoidance and firm behavior.     

我国利息税税负累进程度分析——以北京地区为例

税负累进程度是指税收负担随收入数额的增加而提高的程度,它是衡量税收公平的指标.对我国现行利息税税负累进性的分析表明,当前5%的税率下,利息税的税负累进性微弱,20%的税率更能增强利息税的税负累进性.要强化利息税的公平功能,可能的政策途径有:提高利息税税率;设定起征点,采用累进税率;并入个人所得税实行合并征收;加强对利息税收入的二次分配.     

燃油税政策的国际比较与启示

世界各国征收的燃油税大多是以消费税和增值税为主的多个税种的组合。尽管各国燃油税有差异,但也有许多共性,如燃油课税的主要目的都是作为道路交通建设资金的来源;燃油税多是采取从量定额征收,税费占燃油价格的比例都较高;车用燃料消费所占比例越高的油品,征收环节越靠近生产环节;对非道路用燃料进行税收减免等。本文认为,开征燃油税首要目的是筹集道路养护资金,其次才是促进节能与环保,应综合考虑各种因素来设置税率,并辅之以相应的税收优惠措施。     

“营改增”影响地方政府税收努力研究

基于随机前沿分析法（SFA）测算2011-2015年我国地方政府税收努力程度,并运用双重差分法考察“营改增”对地方征税行为的影响。研究发现：“营改增”将地方税（营业税）变为共享税（增值税）,显著降低了地方政府税收努力程度;改革对税收努力的冲击受经济发展水平、转移支付额度和税收返还的影响,获取转移支付收入和税收返还越多的地区税收努力下降速度越快。后“营改增”时期,如何提高税收效率,缓解地方财政收入对转移支付和债务收入的依赖性,是理顺中央和地方财税关系,完善财税收入体系的重要问题。     

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.     

Controlling Shareholders’ Incentive and Corporate Tax Avoidance: A Natural Experiment in China

The split share structure reform removes a significant market friction in China's capital market by allowing previously non‐tradable shares to be freely tradable at market prices. Such a reform reduces the agency conflict between controlling shareholders and minority shareholders as the former now care more about stock prices. We find that state‐owned firms, but not non‐state‐owned firms, significantly increased their tax avoidance activities after the reform. We attribute this differential effect to the dual role of the government as state‐owned firms’ controlling shareholder as well as the tax claimant. Further, this effect is more pronounced for state‐owned firms that are more likely to be influenced by the government prior to the reform. Finally, the reform reinforces a positive association between tax avoidance and firm value. Overall, our study suggests that when controlling shareholders are more concerned about stock prices, state‐owned firms engage more in tax avoidance activities to enhance firm value.     

Multi‐Factor Effective Corporate Taxation,Firms’ Mark‐Ups and Tax Incidence: Evidence from OECD Countries

This paper provides novel evidence on the multi‐factor effective marginal tax rates (EMTRs) for a sample of 17 OECD countries and 11 manufacturing sectors. We use a single framework encompassing capital, labour and energy taxes. Our cross‐country/cross‐sector approach allows us to analyse the contributions of these input factors to the effective tax borne by firms, taking explicitly into account their degree of substitution, their tax incidence and the role of mark‐ups. We find that the labour tax plays a particularly important role in the overall level of the EMTR and that the presence of mark‐ups can significantly alter the levels of the multi‐factor EMTR, although without significantly altering the ranking of countries. We also find that the bulk of the variation in EMTRs is across countries, rather than across sectors (within countries).     

VAT and agriculture: lessons from Europe

Little has been written about the treatment of agriculture under the value added tax (VAT). This article attempts to fill the void by surveying and evaluating the situation in the Member States of the European Union (EU) and some other countries. Farmers are often exempted from VAT for administrative and political reasons. But this means that the VAT on their inputs cannot be ‘washed out’ through the tax deduction/credit mechanism. It then has to be borne by the farmers themselves or becomes an indeterminate and capricious element in consumer prices. To compensate farmers for the uncompensated VAT on inputs, the EU has devised a flat-rate scheme that permits them to charge a presumptive rate (approximately equal to the effective VAT rate on sector-wide inputs) on their sales to taxable agro-processing firms which, in turn, are permitted to take a deduction for this flat-rate addition from the VAT on their sales. Obviously, the flat-rate scheme is an arbitrary way of trying to achieve equal treatment between exempt and taxable farmers and between exempt farm products and other taxable goods and services. Full taxation, subject to the general threshold, appears to be the preferred choice.     

完善结构性减税政策的着力点与路径选择

根据目前我国所面临的新形势、新任务,完善结构性减税政策的着力点应该放在三个方面:针对特定税种进行有增有减的调整,促进税制结构的优化;针对特定群体实行减税或增税政策,实现税收负担的公平;将结构性减税与经济结构调整对接,助推经济结构的优化。立足于这三大着力点,完善结构性减税政策的基本路径选择为:推进增值税扩围改革;调整消费税;减免部分进口环节税收;实行综合与分类相结合的个人所得税制;进一步完善企业所得税优惠政策;深化个人住房房产税改革;全面推广资源税;研究开征环境保护税等新税种。     

The Capital Structure of Large Firms and the Use of Dutch Financing Entities

Large firms may issue debt securities to obtain external financing or set up lowly‐taxed affiliates for internal debt‐shifting purposes. In addition, they may channel interest payments through Dutch special purpose entities (SPEs) to avoid withholding taxes, a widely‐used arbitrage strategy. Analysing the capital structure of large EU‐based multinationals, this paper provides evidence that the use of Dutch‐issuing SPEs is associated with higher debt financing relative to equity. Furthermore, it shows that EU subsidiaries of larger firms are more leveraged and that the use of Dutch on‐lending SPEs is also associated with higher subsidiary leverage. Thus, the paper provides evidence that Dutch SPEs facilitate higher external debt financing as well as internal debt shifting. The findings indicate that withholding taxes on interest payments to entities outside the EU, determined by individual EU member states, are not very effective. The national tax systems of EU countries such as the Netherlands, which does not impose interest withholding tax, allow large firms to avoid those taxes.     

我国地方税系的重构——基于税收分布视角

地方税系重构需要在考虑地方税收均衡程度的基础上进行,所以,理清税收在各地的分布状况及其差异系数非常关键.分析表明,地方税收的差异系数决定于进入地方税系的税种类别及其在地方税收中的比重.进一步,在中央与地方税收格局不变的限定下,通过模拟计算出地方税系重构八种情景下的地方税收差异系数.同时,基于模拟结果与各种因素的权衡,认为我国地方税系重构不能仅简单依赖增值税分享比例向地方政府的倾斜来实现,而是需要将车辆购置税与部分消费税划归地方政府,之后再以增值税分享比例的调整来稳定地方税收规模.     

Joint Taxation and the Labour Supply of Married Women: Evidence from the Canadian Tax Reform of 1988*

The Canadian federal tax reform of 1988 replaced a spousal tax exemption with a non‐refundable tax credit. This reduced the‘jointness’of the tax system: after the reform, secondary earners’effective‘first dollar’marginal tax rates no longer depended on the marginal tax rates of their spouses. In practice, the effective‘first dollar’marginal tax rates faced by women with high‐income husbands were particularly reduced. Using difference‐indifference estimators, we find a significant increase in labour force participation among women married to higher‐income husbands.
