个人所得税费用扣除问题研究

随着社会经济的发展,个人所得税与人们的关系日益密切,个税费用扣除体制的科学性逐渐成为众所瞩目的焦点。本文对近几年的文献进行总结归纳,深入剖析当前我国个税费用扣除制度存在的弊端,并结合纳税人需求提出完善个税费用扣除制度的建议。     

Taxpayers' Prepayment Positions and Tax Return Preparation Fees*

Individuals who have their tax returns professionally prepared often overpay estimated income taxes, effectively giving the government an interest‐free loan. To understand why tax professionals may place their clients in positive prepayment positions, we draw on mental accounting theory. Mental accounting theory suggests that by placing taxpayers in positive prepayment positions, tax professionals induce a favorable mental representation of tax return preparation fees, perhaps allowing them to collect larger fractions of billable time and costs incurred on taxpayers' behalves. Thus, we hypothesize that tax return preparation fees are higher for taxpayers in positive prepayment positions than for taxpayers in negative prepayment positions. Regression results using tax return data for 68,736 taxpayers provide strong support for this hypothesis. To more fully understand the general nature of the relationship between taxpayers' prepayment positions and tax return preparation fees, we adapt the prospect theory value function to the tax domain and formulate three additional hypotheses. Consistent with theory, regression results indicate that the relation between taxpayers' prepayment positions and tax return preparation fees is (1) positive, (2) stronger for taxpayers who receive refunds that are less than fees than it is for taxpayers who receive refunds that are greater than fees, and (3) stronger for taxpayers in negative prepayment positions than for taxpayers in positive prepayment positions.     

Tax Reporting Behavior Under Audit Certainty

This study uses a confidential data set of firms assigned to the Internal Revenue Service's Coordinated Industry Case (CIC) program to examine the effect of audit certainty on firms' tax reporting behavior. We first model the determinants of assignment to the program. Although the ability and incentive to avoid taxes are related to CIC assignment, we find that the IRS assigns firms primarily based on size and complexity. We then test whether audit certainty has a detectable effect on tax payments. Our results show that tax payments do not change when firms enter the CIC program, suggesting the CIC program does not have higher deterrence or enforcement effects relative to the IRS's standard selection and audit process for large corporations not included in the CIC program. However, supplemental analysis suggests that audit certainty does alter managers' expectations regarding future tax payments. Our paper provides new empirical evidence on the strategic game between the taxpayer and the tax authority and has important implications for tax authorities as they consider the costs and benefits of certain audit programs.     

Tax Advice and Reporting under Uncertainty: Theory and Experimental Evidence*

Abstract. This study extends the Beck, Davis, and Jung (1992) experimental study by incorporating opportunities for taxpayer subjects to purchase advice before making their tax reporting decisions. Tax advice has two roles in the model and experiment. First, tax advice allows taxpayers to reduce their uncertainty about the amount of taxes owed. This permits us to study the demand for tax advice in conjunction with its effect on tax reporting decisions. Second, the decision to purchase tax advice from an expert provides a means of signaling that may alter tax agency audit policies. The resulting audit policies, in turn, can affect taxpayers' decisions to purchase tax advice. These interdependencies are incorporated in a game-theoretic model and several predictions are tested experimentally. Consistent with theory, subjects sorted themselves into three groups based upon their private information. Another prediction supported by the experiment is that the demand for tax advice increased with the magnitude of an uncertain tax deduction (amount-at-risk). We also found, as expected, that the effects of tax advice on pre-audit tax revenues depend upon the amount-at-risk. When the amount-at-risk was high, subjects in settings with tax advice reported lower average incomes and paid lower taxes than did those subjects in settings without the opportunity to purchase tax advice. The opposite was true for the low amount-at-risk condition, supporting our prediction that tax advice and amount-at-risk would have an interactive effect on tax reporting. Analysis was also performed on post-audit tax collections. Contrary to theory, post-audit tax payments were found to increase when subjects had an opportunity to purchase tax advice. This result apparently was caused by a tendency to over-purchase tax advice and, in some cases, to report a low income regardless of the advice received. Résumé. Les auteurs développent l'étude expérimentale de Beck, Davis et Jung (1992) en y incorporant la possibilité pour les sujets contribuables de solliciter des conseils avant de prendre leurs décisions relatives à l'information qu'ils fourniront aux fins fiscales. Les conseils fiscaux jouent deux rôles dans le modèle et l'expérience. Premièrement, ils permettent aux contribuables de réduire leur incertitude relative au montant des impôts auxquels ils sont assujettis. Les auteurs peuvent ainsi étudier la demande de conseils fiscaux en conjonction avec leurs conséquences sur les décisions relatives à l'information à fournir aux fins fiscales. Deuxièmement, la décision de solliciter les conseils fiscaux d'un expert est un signal pouvant influer sur les politiques de vérification des représentants du fisc. À leur tour, ces politiques peuvent influer sur les décisions des contribuables de solliciter des conseils fiscaux. Ces interdépendances ont été intégrées à un modèle de jeu théorique et les auteurs ont vérifié plusieurs prédictions par expérimentation. Conformément à la théorie, les sujets se sont répartis en trois groupes, en fonction de l'information privilégiée dont ils disposaient. L'expérimentation a confirmé une autre prédiction: la demande de conseils fiscaux augmente avec l'importance de la somme dont la déductibilité est incertaine (montant à risque). Les auteurs constatent également, comme ils s'y attendaient, que les effets des conseils fiscaux sur les recettes fiscales antérieures à la vérification dépendent du montant à risque. Lorsque le montant à risque est élevé, les sujets pouvant solliciter des conseils fiscaux font état de revenus moyens inférieurs et paient moins d'impôt que les sujets n'ayant pas la possibilité de solliciter des conseils fiscaux. L'inverse est vrai lorsque le montant à risque est faible, ce qui confirme la prédiction selon laquelle les conseils fiscaux et le montant à risque ont un effet interactif sur l'information fournie aux fins fiscales. Les auteurs analysent également les impôts perçus postérieurement à la vérification. Contrairement à la théorie, ils constatent que les paiements fiscaux postérieurs à la vérification augmentent lorsque les sujets ont eu la possibilité de solliciter des conseils fiscaux. Ce résultat semble être attribuable à une tendance à solliciter des conseils fiscaux avec excès et, dans certains cas, à faire état d'un faible revenu, malgré les conseils reçus.     

Who Benefits from Inconsistent Multinational Tax Transfer‐Pricing Rules?*

This paper uses a strategic tax compliance model to examine taxpayer reporting and tax authority audit strategies in an international setting with two tax authorities. The setting features both information asymmetry between the taxpayer and the tax authorities and inconsistent tax transfer‐pricing rules. The latter creates the possibility of each country trying to tax the same income. We study the effect of the probability of transfer‐price rule inconsistency on the strategies and payoffs of the taxpayer and the tax authorities. We find that an increase in the probability of transfer‐price rule inconsistency induces more aggressive auditing by governments. It therefore deters taxpayers from shifting income to the country with the lower tax rate in situations in which the transfer‐pricing rules are consistent, and can either increase or decrease the income reported to the low‐tax‐rate country in cases in which the transfer‐pricing rules are inconsistent. We find that an increase in transfer‐price rule inconsistency could either increase or decrease the taxpayer's expected tax liability and could either increase or decrease the deadweight loss from auditing. Our results call into question the conventional wisdom that the prospect of double taxation due to transfer‐price rule inconsistency increases a firm's expected tax liability and governments' expected audit costs.     

现代税收意识与税收遵从的提升

现代税收意识与纳税人税收遵从程度高低有着密切的关联。仅仅从加强税收征管的角度来提升纳税人的税收遵从虽然会取得一定的效果,但却不可能从根本上解决纳税人的税收不遵从问题。因此,构建并提高全社会现代税收意识对提升我国现阶段纳税人的税收遵从度有着至关重要的作用。本文针对我国现代税收意识构建中存在的障碍提出了相应的对策建议。     

税务和解的法律价值与社会功能分析

税务和解是指税务机关对于课税基础事实或证据之采认,经过职权调查仍不能确定或虽能够确定但需耗费过巨,为了稽征效率,有效达成课税目的,而与纳税义务人平等协商、互相妥协达成合意的行为或解决方案。通过征纳双方的和解,能够起到定分止争,提高稽征效率,增加国库收入,消除税收债权债务的不确定状态,保障纳税义务人程序参与的功能和作用。     

我国增值税制存在的问题及完善对策

我国现行增值税制度的弊端日益明显：征税范围偏窄与增值税环环相扣、相互制约的要求矛盾;扣税范围不彻底与促进技术进步、优化经济结构的要求矛盾;扣税凭证不规范与保证税收及时足额入库的要求矛盾;税收减免优惠过多、过乱与增值税中性税收的要求矛盾;对纳税人实行差别管理与国民经济发展的要求矛盾。完善增值税制度,应逐步将营业税纳入增值税的征收范围,缩小增值税减免优惠范围,不断增加征收技术投入,提高征收人员素质,逐渐取消两类纳税人的划分办法,坚决推行税制改革。     

Tax incentive,R&D investment and firm innovation: Evidence from China

We estimate the effect of R&D tax incentives on firm-level R&D expenditures (RDE) and patenting using a change in the eligibility criteria for a super deduction in China. In 2006, the Chinese government relaxed the “10 % eligibility criterion”, which stated that only firms with a 10 % or higher increase in prior-year RDE can claim an additional 50 % tax deduction. We use an event study approach to show that firms that became newly eligible to claim the super deduction (those just below the criterion) catches up on RDE and product innovation measured by the sales of new products. In the long run, we also observe a closing gap in the number of patents between the two groups of firms. Moreover, extending tax benefits to all firm helps to lower the tax burden, and we find no evidence of manipulation and relabeling.     

Bond Markets Initiation and Tax Revenue Mobilization in Developing Countries

We analyze the relationship between the introduction of a sovereign bond market (BM) and tax revenue mobilization behavior, using a large sample of 119 developing countries. Propensity Scores Matching estimations reveal that BM participation significantly fosters domestic tax revenue mobilization. Moreover, we find that this favorable effect is sensitive to BM countries' characteristics, namely the stance of monetary and fiscal policies, the exchange rate regime, the level of economic development, and the degree of financial openness and financial development. Finally, our results show that BM participation fosters internal taxes and reduces their instability, compared to international trade taxes. These findings highlight the strength of BM in promoting structural reforms in developing countries, through encouraging them to increase their tax effort and even by contributing to some extent to the fiscal transition process.     

Foreign Holding Companies and the US Taxation of Foreign Earnings: Evidence from the Tax Increase Prevention and Reconciliation Act of 2005*

I analyze US multinationals' (MNCs) use of foreign holding companies in their organizational structures and the impact of holding companies on internal capital markets. The look-thru rule in the Tax Increase Prevention and Reconciliation Act of 2005 (TIPRA) reduces the after-tax cost of foreign intercompany financing transactions. I use TIPRA as a natural experimental setting to test whether a shift in US tax policy that reduces the cost of moving foreign capital increased firms' reliance on foreign holding company subsidiaries. I find that MNCs responded to TIPRA by creating more foreign holding companies. Furthermore, consistent with the policy objectives of TIPRA, I document that MNCs that rely on holding companies gained tax efficiencies in their post-TIPRA foreign internal capital markets, reducing domestic taxation on foreign earnings and easing financial constraints. Overall, my results expand our understanding of foreign organizational structure decisions and their internal financing benefits. I contribute to the tax literature by documenting a response to TIPRA that sheds light on the growing complexity of foreign subsidiary ownership structures.     

减税降费有助于缩小中国家庭经济不平等吗——来自2011年个税改革的证据

共同富裕要求我们从多维视角审视物质层面的不平等，在当前减税降费的大背景下，个人所得税是调控收入分配的关键手段。文章从收入、消费和财产所构成的多维经济不平等视角出发，对2011年个人所得税改革调节家庭经济不平等的效应进行了探讨。研究发现：个人所得税改革的公平效应是显著的，使经济不平等程度下降了13.64%，其中对城市地区的调节效应更强，对低福利阶层和高福利阶层的影响相对显著。在作用机制方面，个人所得税改革主要影响收入不平等，并进一步作用于消费不平等和财产不平等，最终影响经济不平等。为充分发挥个人所得税的调节效应，应逐步提高个人所得税比重，补充和细化专项附加扣除项目与标准，逐步以家庭为基础征收个税。     

Deciphering Tax Avoidance: Evidence from Credit Rating Disagreements

This study investigates the role of tax avoidance in the credit‐rating process and whether differences exist in how rating agencies account for the risk relevance of tax avoidance. Using a sample of initial credit ratings assigned to public debt issuances during 1994–2013, our evidence is consistent with Moody's Investors Service and Standard & Poor's assessing the costs and benefits associated with tax avoidance differently from one another, resulting in more frequent and pronounced rating agency disagreement. Rating agency disagreement over tax avoidance is most evident when it is accompanied by relatively high levels of uncertain tax positions, foreign activities, research and development activities, or tax footnote opacity. We also find evidence that decreases (increases) in tax avoidance or tax footnote disclosure opacity are positively (negatively) associated with the convergence of split ratings. This suggests that firms can exacerbate or mitigate rating agency disagreement subsequent to bond issuance. Our study complements prior research by examining why sophisticated information intermediaries disagree about the risk relevance of tax avoidance. It also sheds light on how firms can influence rating agencies’ understanding of tax avoidance.     

个人所得税税前扣除与税收公平原则

税收具有筹集财政收入和调节经济、调节分配的职能。个人所得税既影响着一个国家的财政收入，又与国民生活质量息息相关，是各国政府十分重视的问题。由于我国在个人所得税领域的税前扣除项目采取的是完全不考虑纳税人的自然状况、家庭负担的扣除方式等，导致了对税收公平原则的违背，直接影响我国建设和谐社会的宏伟目标。对之，一些国家的做法值得我们借鉴。     

Assessing Tax Risk: Practitioner Perspectives

This study uses insights from tax practitioners and tax authorities to define and develop an estimate of ex ante tax risk that is independent of common tax outcomes studied in prior literature. Validation tests confirm that our tax risk measure (i) represents the predictable and unpredictable uncertainty inherent in the three sources of tax risk (i.e., economic risk, tax law uncertainty, and inaccurate information processing) and (ii) is a construct different from tax avoidance, tax uncertainty, and general business risk. Using our tax risk measure, we address two research questions of interest to academics and practitioners. First, we examine the association between tax risk and long-run tax avoidance and find a negative association between tax risk and future long-run cash effective tax rates (ETRs). Second, we consider the extent to which unrecognized tax benefits (UTBs) reflect tax risk, tax avoidance, or financial reporting incentives and demonstrate that our tax risk measure explains a substantial portion of UTBs, incremental and relative to measures of information risk, conditional conservatism, unconditional conservatism, and tax avoidance. Our study offers a measure of tax risk that, consistent with the Scholes-Wolfson paradigm, reflects the tax risk inherent in all business activities, not just tax avoidance activities; has unique industry effects; and contributes to our understanding of the factors that affect tax planning decisions and result in variation in firms' ETRs. Our findings will help managers and tax practitioners focus on industry-specific tax risk components, assess risk during tax planning initiatives, exercise caution when engaging in additional risk if ETRs are low, and adapt tax risk strategies to fit specific company needs. We enhance future tax research by improving the definition and measurement of tax risk.     

税收征管与企业对外投资:来自“金税工程三期”的证据

近些年来，我国对外投资规模迅猛增长，税收征管强度也在不断提升。那么，税收征管是否推动了中国企业的对外投资行为呢？鉴于鲜有文献探讨这一极具现实意义的话题，本文利用"金税工程三期"政策上线这一提高税收征管能力的准自然实验，采用双重差分法首次实证检验了税收征管对企业对外投资行为的影响作用。研究发现："金税工程三期"这一增加企业纳税遵从度、促进"应收尽收"的税收征管政策冲击显著地提高了企业对外投资的可能性、增加了企业对外投资规模，并且这一结论在引入更多控制变量并排除同期其他政策干扰、安慰剂检验、更换样本周期、倾向得分匹配分析等情况下依旧稳健。潜在的影响机制分析发现，"金税工程三期"这一税收征管政策冲击增加了企业的避税动机，表现为企业偏好于向税率低的东道国进行投资。异质性检验结果显示，"金税工程三期"这一税收征管政策冲击对企业对外投资行为的影响作用在不同对外投资事件类型、不同所有制类型的企业、不同地区、不同行业之间存在明显差异。最后，依据本文结论提出了积极落实减税降费政策、适度地提升银行业竞争水平的政策建议。     

我国税收公平目标的再思考及其制度选择

本文对税收公平的内涵作了一种扩张性解释,认为税收公平应包含三个层次的内容,即税收的本质公平、税收的代内公平和税收的代际公平,亦称之为"三层次"税收公平观。为实现税收本质公平,相应的制度选择应是优化政府,保证政府征税权不被滥用,同时重视纳税人权利,构建完善的纳税人权利保护体系;为实现税收代内公平,应做出的制度选择有:努力实现税收的经济公平与社会公平;为实现税收的代际公平,必须构建完善的绿色税收体系并开征遗产税。     

税务和解的法律界定

税务和解是指税务机关对于课税基础事实或证据之采认,经过职权调查仍不能确定或虽能够确定但需耗费过巨,为了稽征效率,有效达成课税目的,而与纳税义务人平等协商、互相妥协达成合意的行为或解决方案。和解的标的为课税基础事实或证据之采认,以此区别于行政和解和辩诉交易。通过对有关行政契约性质的几种观点的分析,税务和解具有有限合意性的性质,以此区别于民事和解。     

个人所得税政策调整影响及进一步改革建议

文章认为,2011年的个人所得税的政策调整,对我国经济生活的方方面面产生了较大的影响。对劳动力供给、个人投资和消费、国家财政以及社会分配等会产生有利的影响;对财政收入等会产生不利影响。同时也应看到,因调整未触及个人所得税转型等根本性问题,费用扣除不合理、分类分项扣除不公平和应对物价上涨乏力等关键性问题没有纳入调整视线,需要待时机成熟时进行相应的改革。     

The Effect of Changes in Income Shifting on Affiliate Managers' Internal Reporting Decisions*†

This study examines the interplay between tax and internal reporting incentives among affiliates of multinational corporations (MNCs). MNCs face limited information flows that may prevent affiliates' performance metrics to be responsive immediately to changes in the firm's tax planning. Using granular data of affiliates belonging to MNCs from 21 European countries, our study provides new empirical evidence of affiliate internal reporting responses induced by changing tax plans. When high-tax-rate countries tighten income shifting rules, we first document that income shifting is reduced and low-tax-rate affiliates have less income. Second, we predict and document that managers of these low-tax-rate affiliates offset this decrease in profits by managing upwards a key performance metric: affiliate earnings. Our results are consistent with firms not quickly adjusting the affiliate managers' incentives in the face of changing tax planning strategies, and affiliates managing reported earnings to offset the effect of changes in the tax planning of the firm. Cross-sectional analyses provide further evidence consistent with the theory underlying the main tests. The results support the policy of tightening income shifting rules when the objective is to reduce income shifting, and firms' central management would benefit from considering the implications of changing tax plans on the assessment of local managers.
