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.     

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.     

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.

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.
