Tax Setting in a Federal System: The Case of Personal Income Taxation in Canada

In a decentralised tax system, the effects of tax policies enacted by one government are not confined to its own jurisdiction. First, if both the regional and the federal levels of government co-occupy the same fields of taxation, tax rate increases by one layer of government will reduce taxes collected by the other. Second, if the tax base is mobile, tax rate increases by one regional government will raise the amount of taxes collected by other regional governments. These sources of fiscal interdependence are called in the literature vertical and horizontal tax externalities, respectively. Third, as Smart (1998) shows, if equalisation transfers are present, an increase in the standard equalisation tax rate provides incentives to raise taxes to the receiving provinces. A way to check the empirical relevance of these hypotheses is to test for the existence of interactions between the regional tax rate, on the one hand, and the federal tax rate, the tax rate set by competing regions, and the standard equalisation tax rate, on the other hand. Following this approach, this paper estimates provincial tax setting functions with data on Canadian personal income taxation for the period 1982–1996. We find a significant positive response of provincial tax rates to changes in the federal income tax rate, the tax rates of competing provinces, and the standard equalisation rate (only for receiving provinces). We also find that the reaction to horizontal competition is stronger in the provinces that do not receive equalisation transfers.     

浅谈个人所得税纳税筹划

21世纪,经济飞速发展,人们的收入水平也在不断的提高.但是,作为一名纳税义务人,依法纳税是我们必须遵守的,收入的提高也就意味着要多缴税,这样一来,原来增长的一部分收入由于要缴纳税金又剩下不多了.于是合理的进行个人所得税的纳税筹划越来越成为人们迫切的要求之一.本文的主要内容就是通过介绍纳税筹划的概念、内容及方法来研究和探讨个人所得税的筹划方法,其中包括避税筹划、节税筹划和转税筹划.指导我们如何在不违反国家税法规定的情况下,合理、有效、持续的节约个人所得税费用,达到收益最大化的目的.     

Taxing Multinationals

This paper analyzes the effects of tax policy on the strategic choices of multinationals and on national welfare. Contrary to existing theory, in the absence of foreign taxation, deferral of home-country taxation until earnings on outbound FDI are repatriated is generally superior to including those earnings in current income. This holds even if the home country taxes domestic investment less generously. This is also generally superior to exempting foreign income. Foreign taxes permit foreign governments to capture some of the pre-tax economic rent from the home-country FDI; this reduces the benefit to the home country of more generous taxation of outbound FDI.     

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。     

我国间接税与收入分配公平关系的实证分析

税收理论认为间接税具有累退性,有利于征管效率但不利于社会公平。采用1994～2009年时间序列数据,计算出库兹涅茨比率以衡量居民收入分配差距,通过对增值税、消费税、营业税、资源税、城建税、全部间接税对库兹涅茨比率影响的实证研究表明,目前我国以增值税为代表的间接税占税收总收入的比重过高,不利于发挥税收调节收入分配差距的作用,需要在今后逐步加以调整;同时间接税中的消费税有一定的缩小我国居民收入分配差距的作用,可以适当加以规范,以发挥其促进社会公平的作用。     

Is Tax Harmonization Useful?

It is a widely acknowledged result of the literature on international tax competition that an inefficient provision of public goods can only be avoided, if taxes are sufficiently coordinated. In this paper we use a model where governments use commodity and factor taxes in the tax competition game. We show that governments will always choose a second-best efficient tax structure in the Nash equilibrium if they have access to a residence-based capital tax and either a destination-based commodity tax or a labor tax. Moreover, we show that tax competition need not foreclose third-best efficiency in a world with a restricted tax policy toolkit.     

Is Targeted Tax Competition Less Harmful than its Remedies?

Some governments have recently called for international accords restricting the use of preferential taxes targeted to attract mobile tax bases from abroad. Are such agreements likely to discourage tax competition or conversely cause it to spread? We study a general model of competition for multiple tax bases and establish conditions for a restriction on preferential regimes to increase or decrease tax revenues. Our results show that restrictions are most likely to be desirable when tax bases are on average highly responsive to a coordinated increase in tax rates by all governments, and when tax bases with large domestic elasticities are also more mobile internationally. Our analysis allows us to reconcile the apparently contradictory results of the previous literature.     

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.     

财产税改革的逻辑

财产税与地方财政有着紧密的联系,多数划归为地方税。从财产税的性质来看,也适宜做地方税。这表明财产税的功能设计只能是以筹集收入为主,调节为辅。由此,财产税改革就应注重从宽税基、简税制和易征管,以及结合我国地方财政体制改革的要求来设计。我国财产税改革:一是替代原来已经不合时宜的相关税种;二是替代基层政府不具有地方税属性的税种。这两个”替代”若能实现,便可以”一箭双雕”,既能完善税制,又能理顺政府间财政关系。     

Fiscal Policy Reforms in a Global Economy

Two countries are populated by workers and capitalists. Their governments collect taxes to finance productive expenditure and income redistribution. The share of income redistributed defines the size of the welfare state. Although both groups benefit from an abolition of the welfare state in the long run, the optimal fiscal policy in autarky can be characterized by maintaining a large welfare state since transfer cuts would induce transitional losses. Starting in such a position of policy inertia free trade and capital mobility is introduced. Fiscal policy competition leads to a reduction of tax rates and a relative increase of productive expenditure. If both countries coordinate their fiscal policy the reduction of taxes and income transfers is less pronounced. Quantitative effects of increasing globalization are assessed in a calibrated model for an average Europe G-4 country and the United States.     

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。     

Political Sustainability and the Design of Environmental Taxes

This paper studies the issue of political support for environmental taxes. The environmental tax is determined by majority voting, given a refund rule that specifies the allocation of tax proceeds. The refund rule is chosen by a welfare-maximizing constitutional planner. We show that: (i) The equilibrium tax rate is increasing in the proportion of tax reductions based on wage incomes. (ii) If labor and capital income taxes are reduced in the same proportion, to keep the government's budget balanced, majority voting yields a rate of environmental taxation that is lower than the optimal (Pigouvian) level. (iii) To mitigate this negative bias, the government reduces wage taxes by a higher proportion than capital income taxes. (iv) The final outcome will either be the Pigouvian tax or else all reductions will be given in wage taxes. This depends on individuals' preferences for the polluting good as well as wage and capital income distributions.     

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.     

Can Capital Income Taxes Survive in Open Economies?

Optimal-tax theory forecasts that small open economies should not tax capital income. Yet, countries do tax capital income. Why the inconsistency? This paper shows that use of the double-taxation convention, whereby governments credit taxes paid abroad against domestic taxes, helps explain this inconsistency. In particular, capital income will be taxed if a dominant capital exporter acts as a Stackelberg leader when setting its tax policy. Due to the convention, other countries will then tax capital imports, making it attractive for the dominant capital exporter to tax capital income. Without a dominant capital exporter, however, the model still forecasts no capital-income taxes.     

税制结构演变的国际经验与中国展望

税制结构的演变受到经济因素、政府政策目标、国家和社会关系的影响和约束,具有普遍的规律性。考察世界各国税制结构的演变历程可以发现,发达国家税制结构和税种结构均比较稳定,直接税占比高但税种分散,货物与劳务税仍为最大的单一税种;发展中国家税制结构相对稳定但税种结构呈趋势性变化,个人所得税和企业所得税均稳中有升。个人所得税和社会保障缴款是国家间税制结构差异的主要来源,企业所得税负担的国际竞争面临深刻变化。当前我国已基本形成了双主体税制结构,直接税收入中所得类税收、企业主体税收占比较高。鉴于此,我国应在强化均贫富、促消费的目标下,提高个人所得税比重、完善财产税制度、加强自然人税源管理;在新经济增长模式下,对增值税进行适应性调整和税负优化。     

美国州际公司所得税协调机制及对我国的启示——以MTC为例

新的企业所得税法关于汇总纳税的规定使我国面临着大规模的地方政府间所得税分配问题。然而这一问题并非我国所独有。美国跨州税收委员会(MTC)是美国州际公司所得税协调机制的重要组成部分,考察MTC的成立背景和近40年的协调实践活动,有助于加深对我国企业所得税分配问题的理解,并得出有益的启示。     

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.     

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 Stability of Tax Elasticities over the Business Cycle in European Countries

We estimate short‐ and long‐run tax elasticities that capture the relationship between changes in national income and tax revenue. We show that the short‐run tax elasticity changes according to the business cycle. We estimate a two‐state Markov‐switching regression on a novel data set of tax policy reforms in 15 European countries from 1980 to 2013, showing that the elasticities during booms and recessions are statistically (and often economically) different. The elasticities of personal income taxes, corporate income taxes, indirect taxes and social contributions tend to be larger during recessions. Estimates of long‐run elasticities are in line with existing literature.     

中印地方税制度比较分析

我国和印度的地方税①制存在明显的差异。印度的地方税制具有较强的法制性、完整性和自主性。本文认为,我国的地方税制改革可以借鉴印度的一些先进经验,把重点放在加速税收基本法的建设、增强地方政府征税的合法性、扩大地方税的覆盖范围、完善地方税税种体系和税制结构以及提高地方税收入占整个地方政府税收收入的比重上。
