From the global income tax to the dual income tax: Recent tax reforms in the Nordic countries

The paper discusses the recent drive toward a system of dual income taxation (DIT) in the Nordic countries. The pure version of this system combines progressive taxation of labor and transfer incomes with a proportional tax on income from capital at a level equal to the corporate income tax rate. The paper considers the motives for the introduction of this new income tax system, ranging from abstract theoretical arguments to very pragmatic considerations. While the Nordic DIT system violates the principles of the conventional personal income tax, it is argued that it may in fact be more in line with the philosophy of a true Haig-Simons comprehensive income tax. It is also suggested that the DIT system may cause fewer distortions to resource allocation than the conventional income tax. On the debit side, the paper points out several practical problems of taxing income from small enterprises under the differentiated income tax.     

The tax benefit of income smoothing

A worker can reduce tax liability by contributing to a private pension plan when marginal tax rates are high and withdraw pension benefits when marginal tax rates are low. We quantify the tax benefit of income smoothing through the private retirement system and find that it is negligible. This conclusion is important to households, investment advisers, tax policymakers, and scholars engaged in financial retirement planning.     

Corporate and personal income tax declarations

Decisions by firms and individuals on the extent of their tax payments have generally been treated as separate choices. Empirically, a positive relationship between corporate and personal income tax evasion can be observed. The theoretical analysis in this paper shows that a manager's decision on the firm's behaviour will be independent of his personal preferences if the gain from reducing corporate tax payments is certain, as in the case of tax avoidance. If, however, the firm evades taxes so that the manager's income depends on whether the firm's activities are detected or not, corporate and personal income tax evasion choices cannot be separated.

The impact of tax enforcement on corporate investment efficiency: evidence from the tax administration information system

Information technology is essential in tax enforcement. This study found that stronger tax enforcement after the tax administration information system reform improved corporate investment efficiency by reducing excessive investment expenditures. The effect is more significant under higher local government fiscal pressure, poorer external information environments, weaker external corporate governance, and stronger tax avoidance motivation. The main mechanism is based on the quality of the accounting information. This study enriches the literature on the economic consequences of tax enforcement and adds investment efficiency as an influential factor, which provides implications for international governments to use information technology to strengthen tax enforcement.     

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.     

Economic policy uncertainty and firm tax avoidance

We find strong evidence that firms reduce cash effective tax rate when economic policy uncertainty heightens. Firms also engage in more aggressive forms of tax avoidance including long-term tax planning or shelters. Cash holdings attenuate the negative effect of policy uncertainty on cash effective tax rate, especially for financially constrained firms. The cash tax savings are retained for reinvestments rather than dividend payouts. Our findings suggest that policy uncertainty exacerbates external financing frictions, which in turn induces precautionary motives of tax avoidance.     

The intoxicating brew of black liquor and son of black liquor: Deciphering the tax planning,research, policy and financial statement implications of tax credits via financial reporting income tax disclosures

In 2007, a change in the law regarding the alternative fuel mixture credit opened the door for paper mills to qualify a byproduct of paper manufacturing, black liquor, as a fuel eligible for the credit. The credit is a refundable credit of $0.50 per gallon. Paper mills can produce hundreds of millions of gallons of black liquor per year and qualified for the credit in 2009. In addition, in 2010 the IRS determined that these firms qualified for the cellulosic biofuels producer credit. Paper mill companies could amend their 2009 tax returns and swap their alternative fuel mixture credits for cellulosic biofuels producer credits worth $1.01 per gallon. The catch was that the alternative fuels mixture credit was refundable; the cellulosic biofuels producer credit was nonrefundable.     

Establishing bounds on the tax advantage to debt

The partial dismantling of the imputation tax system that commenced in July 1997 once more opens the discussion on the relative tax advantage to debt and its impact on the cost of capital. In this paper we examine the implications of these recent changes for the value of the tax advantage to debt. We analyse the value of debt-related tax shields by computing the individual tax liabilities of 1268 quoted companies that reported during the period 1980–2000 taking account of any tax exhaustion or surplus ACT. We use these estimates to establish an upper bound on the tax advantage to debt. We conclude that even following the 1997 changes in the imputation tax system the probable value for the average current tax advantage to debt in the UK at present is at most about 13% of the value of debt.     

Corporate tax aggression and debt

We provide a tradeoff model of the capital structure that allows leverage to be a function of a firm’s choice of tax aggressiveness. The model’s testable implications are supported empirically. Debt use is inversely related to corporate tax aggression for most firms, and the relation is economically important. This substitution effect is especially evident for firms exhibiting high tax-shelter prediction scores. The effect attenuates for benign forms of tax avoidance and during the recent credit crisis period. For the most profitable firms, debt and tax aggression are complements. Our results extend the empirical findings of Graham and Tucker (2006).     

The effects of standardized tax rates,average tax rates,and the distribution of income on tax progressivity

This study examines the changes in US individual income tax progressivity over the 1986–2003 period using the indexes developed by [Kakwani, N.C., 1976. Measurement of tax progressivity: An international comparison. Economic Journal 87(March), 71–80]. Although progressivity over this time frame has generally been studied in the literature, we provide additional insights by decomposing the changes in index values to account for the effects of concurrent changes in the standardized tax rates, average tax rates, and the income distribution. The decomposition should prove to be particularly useful when different summary indexes lead to conflicting conclusions about progressivity changes, as is often the case. From a policy standpoint, we show that it is the standardized tax rates, a derivative of the legislated tax rates, which need to be monitored and managed to offset the negative progressivity effects of increasing before-tax income inequality.     

The roles of book‐tax conformity and tax enforcement in regulating tax reporting behaviour following International Financial Reporting Standards adoption

This study investigates whether increasing the level of tax enforcement can potentially offset the primary cost of a reduction in the level of book‐tax conformity (BTC) following International Financial Reporting Standards (IFRS) adoption – increased tax avoidance. We find that after the decrease in BTC and the concomitant increase in tax enforcement that followed IFRS adoption in Israel, tax avoidance declined significantly. Our results imply that one of the primary costs of reducing BTC can be avoided. Moreover, the results suggest that rather than one strict regulatory approach to deal with reporting manipulations, a combination of trust and control is more effective and less radical.     

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.

Evidence of the effect of domicile on corporate average effective tax rates in the European Union

We estimate (worldwide) corporate average effective tax rates (ETRs) from financial statements for companies domiciled in European Union (EU) member states during 7 years from 1990 to 1996. Our objective is to compare the tax rate effectively experienced by each company with the corporate statutory tax rate (STR) in the EU country in which each company is domiciled. The difference between the corporate statutory tax rate and the financial statement-based corporate average effective tax rate provides information on the magnitude of tax incentives provided by governments within the EU. These tax incentives come on top of the directly observable differences in statutory tax rates between EU member states. We find (1) that the use of tax incentives, over and above differences in STRs, differs substantially between EU member states (corporate domiciles) and (2) that the provision of tax incentives does not have the effect of equalizing corporate ETRs between EU member states (corporate domiciles).     

Determinants of tax evasion: A cross-country investigation

The purpose of this study is to expand on the work of Riahi-Belkaoiu [Riahi-Belkaoiu, A. (2004). Relationship between tax compliance internationally and selected determinants of tax morale. Journal of International Accounting, Auditing and Taxation, 13, 135-143] and systematically investigate, on a cross-country basis, many of the key determinants of tax evasion identified by Jackson and Milliron [Jackson, B. R., & Milliron, V. C. (1986). Tax compliance research: findings, problems and prospects. Journal of Accounting Literature, 5, 125-165]. Based on data for 45 countries, the results of the OLS regression analysis show that non-economic determinants have the strongest impact on tax evasion. Specifically, complexity is the most important determinant of tax evasion. Other important determinants of tax evasion are education, income source, fairness and tax morale. Overall, the regression results indicate that the lower the level of complexity and the higher the level of general education, services income source, fairness and tax morale, the lower is the level of tax evasion across countries. These findings remain robust to a broad range of cross-country control variables, an alternative tax evasion measure and various interactions.     

房地产投资与金融效率——金融资源“脱实向虚”的地区差异

通过构建一个包含投资结构和金融发展的内生增长模型,本文发现,房地产投资占固定资产投资的比重偏离其最优结构且继续上升,对金融效率具有抑制效应,不利于金融支持实体经济发展。而且,这一抑制效应在房地产外部性越弱的地区越强。基于2003-2013年地级市层面的样本,采用两阶段系统广义矩估计法和工具变量法的实证分析结果均支持了模型的结论。进一步的分析表明,房地产投资对金融效率的抑制作用在西部地区、经济欠发达地区和房地产销售状况较差的地区更强。     

Horizontal inequity under a dual income tax system: principles and measurement

Tax systems with separate taxation of wage and capital income, also called dual income tax systems, have gained relevance through the Mirrlees Review. Obviously, such tax systems are exposed to horizontal equity (HE) failures, or horizontal inequity (HI). HE and HI have a firm grip on assessment of fair tax policies, both from an academic point of view and in general public debate. The dual income tax system of Norway was modified by the tax reform of 2006 precisely because the previous schedule failed to deliver equal tax treatment of equals. This paper discusses the meaning and measurement of HI effects of dual income tax systems, and evaluates the development of HI for Norway over the time period 2000–2008 using microdata. A copula-based identification strategy efficiently establishes a framework for evaluations of HI over time. The dual income tax system and the early announcement of its impending revision during the period under examination created measurement problems which we had to account for by defining a new income concept for the empirical strategy. As expected, we find less HI in Norway after the reform of 2006.     

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.     

Credit refinancing and corporate tax avoidance

This study examines the disciplining effects of credit markets on firms’ corporate tax avoidance strategies. We show that, during adverse credit market conditions, firms with refinancing needs prefer to limit the after-tax cash flow benefits of tax avoidance to regain access to traditionally risk-averse credit markets. Our results show that firms increase their cash effective tax rate by two percentage points when facing refinancing constraints, and this effect is more pronounced for firms with lower asset redeployability and higher default probability. However, corporate governance mechanisms mitigate the relationship between tax avoidance and credit refinancing. Moreover, we show that firms decrease their tax avoidance strategies while leaving their leverage and debt shield unchanged. Overall, our findings are consistent with the observation that credit markets put pressure on tax-avoiding firms and contribute to the policy debate on disciplining tax avoiders.     

Tax credits,income support,and partnership decisions

This paper considers the potential impact of welfare benefits on the partnership status of women in the UK. Using recent policy reforms to identify the response rate, it was found that a ￡100/week welfare benefit “partnership penalty” reduces the probability of a woman having a partner by seven percentage points. The model is also used to explore the potential effects of the recent tax credit reforms on partnership rates; it was found that while the 1999 WFTC reform improved partnership incentives, this effect was effectively undone by the 2003 WTC/CTC reform.
