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.     

Corporate income taxation in Lithuania in the context of the EU

This paper explores Lithuania's competitiveness in the area of corporate income taxation. In order to assess how much freedom of action the country has in designing its own corporate income tax policy, the process of EU tax harmonization is analyzed by evaluating justification for tax harmonization, the major developments and the main outcomes of this process. Lithuania's corporate income tax system is compared with the systems in the other EU countries. Following a macro backward-looking approach, the paper calculates the measures of effective profit tax burden. Effective tax burden measures are computed for the whole enlarged EU. Such calculations are still rare in the economic literature.     

Federal income tax laws that cause individuals’ marginal and statutory tax rates to differ

This article presents a “phaseouts table” as a tax educational tool. The table compiles and summarizes the phaseouts of and limitations on deductions, credits, exclusions from income, and allowed contributions for individual U.S. federal income taxpayers in 2013. Phaseouts can cause individual taxpayers’ marginal tax rate (MTR) to be higher than their statutory tax rate (STR) (i.e., “bracket” based on taxable income). For each phaseout, the table includes how the phaseout works, the adjusted gross income (AGI) range for the phaseout, and the related formula to compute MTR, given STR. The table is appropriate for any course that covers either U.S. federal income taxation of individuals or tax planning. (The phaseouts table is updated annually and is available upon request from the author.) The remainder of the article is a teaching resource, explaining how to compute the specific impact on MTR of each of several example phaseouts. Together, the phaseouts table and article enable U.S. tax instructors to assist students in learning about phaseouts in an integrated, comprehensive manner.     

Tax treatment of dividends and capital gains and the dividend decision under dual income tax

The paper analyses efficiency aspects of a dual income tax system with a higher tax on capital gains than dividends. It argues that apart from the distortions to investments claimed in earlier literature, the system puts even more emphasis in creating incentives for entrepreneurs to participate in tax planning. The paper suggests that the owner of a closely held company can avoid all personal taxes on entrepreneurial income by two tax-planning strategies. The first is the avoidance of distributions, which would be taxed at the tax rate on labour income. These funds would instead be invested in the financial markets. The second strategy is a distribute and call-back policy, converting retained profits into new equity capital. Interestingly, the outcome is that investment in real capital is not distorted in the long-run equilibrium. Empirical evidence using microdata is also provided.      

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.     

Fundamental Tax Reform in The Netherlands

The Netherlands has abolished the tax on actual personal capital income and has replaced it by a presumptive capital income tax, which is in fact a net wealth tax. This paper contrasts this wealth tax with a conventional realization-based capital gains tax, a retrospective capital gains tax with interest on the deferred tax, and a mark-to-market tax which taxes capital gains as they accrue. We conclude that the effective and neutral taxation of capital income can best be ensured through a combination of (a) a mark-to-market tax to capture the returns on easy-to-value financial products, and (b) a capital gains tax with interest to tax the returns on hard-to-value real estate and small businesses.

Why Capital Income Taxes Survive in Open Economies: The Role of Multinational Firms

This paper discusses the role of multinational firms and double taxation treaties for corporate income taxation in open economies. We show that it is optimal for a small open economy to levy positive corporate income taxes if multinational firms are taxed according to the full taxation after deduction system or the foreign tax credit system. Positive corporate taxes also occur in the asymmetric case where some countries apply the exemption system and others apply the tax credit system. If all countries apply the exemption system, the optimal corporate income tax is zero. We also show that, under tax competition, corporate income taxes are not necessarily too low from the perspective of the economy as a whole. While the undertaxation result is confirmed for the case of the exemption system, tax rates may also be inefficiently high if the deduction or the credit systems are applied.     

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.     

论个人所得税的二元课税模式

由于综合个人所得税制在理论基础和实际征管方面都存在着难以克服的困难,发端于北欧国家的对劳动所得适用累进税率而对资本所得适用比例税率的二元个人所得税制就成为一种较为现实而理想的模式,在国际上正得到日益广泛的支持。我国近年提出的综合与分类相结合的个人所得税制模式近似于二元所得税制,应当作为个人所得税改革的长远目标,但还需对具体制度安排进行恰当的设计。     

Capital Mobility and Source-Based Taxation of Capital Income in Small Open Economies

This paper examines the taxation of capital income in a small open economy that faces a highly elastic supply of internationally mobile capital and increasing tax competition. The analysis considers a wide variety of additional factors that affect the determination of capital income taxation policy, including the desire to tax economic rents earned by foreign and domestic firms, the desire to take advantage of any treasury transfer effects, the role played by transfer pricing and other financial accounting manipulations by foreign multinationals, the need for a backstop to the personal income tax and various political concerns. The paper evaluates several potential income and consumption-based tax reforms in this context. JEL Code: H21, H25, H87     

Neutral Taxation of Shareholder Income

A Norwegian tax reform committee recently proposed a personal tax on the realized income from shares after deduction for an imputed risk-free rate of return. This paper describes the design of the proposed shareholder income tax and shows that it will be neutral with respect to investment and financing decisions and decisions to realize capital gains, provided that full loss offsets are granted. Thus the tax allows some non-distortionary double taxation of corporate equity income. With an appropriate choice of tax rates, it also solves the problem of income shifting under a dual income tax.

Information system and corporate income tax enforcement: Evidence from China

This paper adds the literature by investigating the effect of information system on corporate income tax (CIT) enforcement. We exploit the regional variations generated by the implementation in 2013 of the third stage of the China Tax Administration Information System (CTAIS-3) pilot. The CTAIS-3 is a nationally unified information system that significantly reduces information asymmetry between different tax authorities across regions. We find that the CTAIS-3 pilot significantly reduced firms’ conforming and non-conforming tax avoidance. The enhanced tax enforcement is particularly prominent if a firm is of a smaller size, or is administrated by the State Administration of Taxation, or is a non-state-owned enterprises, or locates in cities with a higher level of local fiscal pressure. Furthermore, we show that the CTAIS-3 improved the CIT enforcement by deterring firms from underreporting accounts receivable, as well as over-reporting accounts payable, inventory and the number of employees. In general, it would be more difficult for firms to hide profits from tax authorities under the CTAIS-3.     

Progression and revenue effects of income tax reform

Usually, only initial revenue effects of personal income tax reforms are considered. However, a tax reform characterized by base broadening in exchange for rate reduction can reduce the income elasticity of tax revenue. In that case, the increase in revenue after income growth will be relatively smaller: the tax reform has a negative effect on revenue in the second period. Using the microtax model of the Central Planning Bureau we simulated the effects of the Dutch Oort reform 1990 on revenue elasticities and, consequently, on tax revenue. The income tax revenue elasticity declined by 17 percent which caused an additional revenue loss of 0.6 percent in 1990, rising to 3.8 percent in 1993.     

Compliance costs for personal income tax in a transition country: the case of Slovenia

The evaluation of taxpayers' compliance costs has grown in significance within tax system research over the last 15 years. In 2001, two surveys of VAT and personal income taxpayers were conducted in Slovenia to evaluate compliance costs for the 2000 fiscal year. This paper presents the results of research into compliance costs for personal income tax in Slovenia. The results show that compliance costs for personal income tax are relatively low, primarily because most taxpayers consider filing their tax declaration to be a simple procedure, which means that consultancy costs are low.     

The incentive to locate a multinational firm: The effect of tax reforms in the United Kingdom

The advent of the single European market has focused attention on the structure of international tax incentives for the location of multinational business. Multinationals that channel foreign income through the United Kingdom have been likely to suffer double taxation in the form of surplus advance corporation tax when they subsequently distribute the income to a foreign parent. This paper shows that the 1993 U.K. tax reforms create a significant reduction in the tax cost of locating in the United Kingdom, relative to traditionally favorable tax regimes such as the Netherlands.     

Meta-analysis categorization of EU countries in the context of corporate income tax

The corporate income tax is a corporate tax which aggregates economic, political and social aspects. The paper focuses on identification, analysis and assessment of homogenous EU countries groups, which show the common characteristics in the field of corporate taxation based on the selected segmentation criteria. Within the statistical meta-analysis in this paper some several methodical approaches were used: variants of agglomerative hierarchical cluster analysis, k-means method and fuzzy c-means and also multidimensional scaling method are implemented and compared. The purpose of this research is, in the context of theoretical implication to provide a synthesis of knowledge and empirical evidence about selected determinants of corporate taxation, and to verify the applicability of the clustering methods when gaining knowledge in the field of taxation. In the context of practical implication is the main purpose of this research the categorization of European countries into economically meaningful clusters, based on their similarity in corporate taxation, and to assess the convergence of European countries in corporate taxation. Results of provided cluster analysis are five groups of multidimensional objects with distinctive characteristics: nominal and effective corporate tax rate, economic performance and the level of debt.     

权衡中的创新——双元所得税评介

双元所得税是与综合所得税、单一税并列的一种个人所得税的主要模式,其特征为双元税基、双元税率和限制优惠。双元所得税的优点是兼顾了税收收入和国际竞争力、兼顾了效率和一定程度的收入再分配、避免了对资本的重复课税、降低了由于通货膨胀带来的对资本所得的过度课税、简化了税制。双元所得税契合了北欧各国社会经济状况对税制的要求,因此,成为北欧国家个人所得税的首选模式。
