Tax evasion, tax morale and policy maker's effectiveness

This paper aims to show that aggregate tax evasion may be largely explained by tax morale and that tax morale is dependent on the taxpayers’ intrinsic attitudes to honesty and social stigma. The theoretical hypothesis is that these attitudes are influenced by the taxpayers’ perceptions of the size of tax evasion as well as by their perceptions of the policy maker's effectiveness in exercising control over the relevant macroeconomic variables and safeguarding the interests of citizens. Applying Gordon's [Gordon, J.P.F., 1989. Individual morality and reputation costs as deterrents to tax evasion. European Economic Review 33(4), 797–805] framework, a dynamic model of aggregate tax evasion is proposed whereby multiple equilibria may emerge. Econometric analysis on Latin American countries supports the assumptions made in the model.     

A measuring instrument to evaluate e-service quality in a revenue authority setting

Tax revenue forms the backbone of any economy. The quality of the e-services provided by a revenue authority is therefore crucial, as e-service quality directly influences the burden of complying with tax obligations, and hence affects the tax compliance climate in a country. The aim of the study is the development of a measuring instrument that encapsulates the ‘lens of a tax practitioner’ in an e-service revenue authority setting. In order to develop a conceptual framework, an in-depth, qualitative approach was used to identify a comprehensive range of service attributes and dimensions that potentially drive e-service quality in the revenue authority setting. This framework is then compared with other relevant service quality models to derive at a proposed e-service quality-measuring instrument. Findings from this study may advance the understanding and the management of the e-service quality of the e-services in a revenue authority setting.     

Perceptions of taxation: A comparative study of different population groups in South Africa

South Africa is a country of diverse cultures, languages, beliefs and backgrounds. It is conceivable that these different population groups may have differing perceptions of taxation resulting from their cultural backgrounds or even their political and social histories. These perceptions may, in turn, influence their attitudes towards tax compliance. It is, therefore, argued that in order to change taxpaying behaviour, perceptions must be first be identified, and then influenced in a positive way towards tax compliance.     

Income tax evasion dynamics: Evidence from an agent-based econophysics model

We analyze income tax evasion dynamics in a standard model of statistical mechanics, the Ising model of ferromagnetism. However, in contrast to previous research, we use an inhomogeneous multi-dimensional Ising model where the local degrees of freedom (agents) are subject to a specific social temperature and coupled to external fields which govern their social behavior. This new modeling frame allows for analyzing large societies of four different and interacting agent types. As a second novelty, our model may reproduce results from agent-based models that incorporate standard Allingham and Sandmo tax evasion features as well as results from existing two-dimensional Ising based tax evasion models. In this way, such kind of models may become more relevant and useful in economics as well as social psychology. We finally use our model for analyzing income tax evasion dynamics under different enforcement scenarios and point to some policy implications that may also be of interest for psychological research on tax compliance.     

Reference dependent preferences,hedonic adaptation and tax evasion: Does the tax burden matter?

We study the effects of the tax burden on tax evasion both theoretically and experimentally. We develop a theoretical framework of tax evasion decisions that is based on two behavioral assumptions: (1) taxpayers are endowed with reference dependent preferences that are subject to hedonic adaptation and (2) in making their choices, taxpayers are affected by ethical concerns. The model generates new predictions on how a change in the tax rate affects the decision to evade taxes. Contrary to the classical expected utility theory, but in line with previous applications of reference dependent preferences to taxpayers’ decisions, an increase in the tax rate increases tax evasion. Moreover, as taxpayers adapt to the new legal tax rate, the decision to evade taxes becomes independent of the tax rate. We present results from a laboratory experiment that support the main predictions of the model.     

Behavioral dynamics of tax evasion – A survey

Since the 1950s (Schmölders, 1959) it is well known that behavioral aspects have an influence on tax evasion or tax compliance. In particular, interactions among the various entities involved in the taxation process (e.g. taxpayers, law makers, tax practitioners, tax authorities, etc.), and the dynamics that these interactions may generate, seem to play an important role for the actual level of tax compliance. However, the mainstream neoclassical approach to tax evasion (Allingham & Sandmo, 1972) cannot account for such interactions and dynamics. Therefore, during the last two decades new approaches (e.g. lab experiments, agent-based modeling, etc.) have been developed with a view to model how behavioral dynamics may foster or prevent tax evasion. In addition, empirical evidence has been generated that supports a role for such interaction dynamics. In this contribution we survey the main developments in this research area and provide some suggestions for further research.     

Work performance and tax compliance in flat and progressive tax systems

Different tax systems, and their impact on work motivation and tax compliance are significant issues in contemporary political and economic debates. The proportional feature of a flat tax system is assumed to lead to higher performance, while the fairness of the redistributive progressive tax system is assumed to result in higher tax compliance. However, empirical findings on the topic are inconclusive. Both work performance and tax compliance under different tax systems were examined in an experiment, with special attention devoted to the effect of a change in tax systems. A flat tax system was supposed to induce greater work performance, whereas a progressive tax system was expected to increase tax compliance based on fairness perceptions, allowing for the opposite effect due to higher complexity. Furthermore, it was assumed that performance and tax payments would be influenced by motives of self-interest. The design included 20 rounds with a real-effort task in each round, determining participants’ experimental income. Participants (N = 191) made decisions about their tax payments from round-to-round in four different experimental conditions: (1) a flat tax system, (2) a progressive tax system, (3) starting with a flat and changing to a progressive, and (4) starting with a progressive and changing to a flat tax system. Results indicate higher work performance in a progressive system. However, a change from a progressive tax system to a flat system led to increased tax compliance.     

Mental accounting of income tax and value added tax among self-employed business owners

Mental accounting describes a series of cognitive operations that help organize financial activities and facilitate money management. Self-employed taxpayers who make use of a separate mental account for future income tax payments or collected value added tax (VAT) might find it easier to declare their taxes correctly than taxpayers who do not. This study used a questionnaire to investigate whether self-employed taxpayers (N = 350) use mental accounting to manage their income tax and VAT obligations, whether mental accounting relates to tax knowledge, business and personality characteristics, and to what extent mental accounting is related to intended tax behavior. Our results reveal that some taxpayers mentally segregate taxes from turnover (segregators) while others do not (integrators). We found small differences in mental accounting between income taxes and VAT. Moreover, confirmatory factor analyses suggested that tax knowledge and mental accounting are distinct constructs. Segregation of taxes was related to lower impulsivity and more positive attitudes toward taxation. Individuals who stated they segregate taxes due from turnover more often claimed to run financially prosperous businesses. Mental accounting was not related to intentions of evading taxes, but individuals with higher mental accounting scores reported more pronounced levels of tax planning. While our research design does not allow drawing causal inferences, these findings could suggest that increasing self-employed taxpayers’ ability to organize their financial activities might be a promising strategy to strengthen the competitiveness of their businesses.     

Service quality framework for the South African Revenue Service from the perspective of the tax practitioner

The objective of the present research was to propose a service quality framework regarding the service quality of the South African Revenue Service (SARS) from the perspective of the tax practitioner. In order to develop the specific “lens of the tax practitioner” regarding the service quality of SARS, an in-depth, qualitative approach was required to identify a comprehensive range of determinants that potentially drive service quality in the revenue service industry and setting. One such qualitative method is the critical incident technique, which relies on a set of procedures to collect comments on service experiences, to perform a content analysis and to classify the observations of service experiences. A process of natural language argument was used to convert the data analysis results and the relevant elements of the theory from the literature survey into the service determinants. This “lens of the tax practitioner” can be used as a basis for developing a service quality measuring instrument that could measure the service quality of SARS from the perspective of the tax practitioner.     

A self-interest analysis of justice and tax compliance: How distributive justice moderates the effect of outcome favorability

Compliance with tax authorities has been studied mainly in the fields of economics and psychology. The focus has respectively been on self-interest motives and justice concerns in tax compliance. We argue that both concerns are less divergent than is often thought. Specifically, we studied the moderating role of distributive justice on the relationship between outcome favorability and tax compliance in two cross-sectional surveys. It is generally believed that favorable outcomes increase compliance because they decrease what can be gained from non-compliance. The present research addresses the role of distributive justice in this process. Since people believe that distributive fairness guarantees their long-term outcomes, favorable present outcomes now imply favorable future outcomes and unfavorable present outcomes now imply unfavorable future outcomes. Thus, we expected fair outcomes to result in a strong relationship between outcome favorability and compliance. On the basis that unfair outcomes are believed to result from chance, outcome favorability should have a weaker relationship with compliance when outcomes are unfair. Even when controlling for other variables, this prediction was supported by both studies.     

Taxes: Attitudes and perceptions and their social bases

The results of an analytical study are reported, attempting to examine the social bases of perceptions and attitudes regarding taxes and the tax system. The research focuses on three major issues: Tax consciousness; satisfaction with the fiscal system and specific taxes within it; and perceptions about the equitability of the tax system. The investigation is based on a city sample of 360 household heads in Israel. The findings indicate that the issues investigated are much more complex than is assumed in the prevalent literature. Thus, tax consciousness is not simply a result of the technicalities of tax collection as is often assumed; the satisfaction with taxes is not so much affected by their visibility or by their level of equitability as it is by other social factors; and perceptions of equitability are affected by social factors rather than by objective equitability.     

The effects of official and unofficial information on tax compliance

The administration of tax policy has shifted its focus from enforcement to complementary instruments aimed at creating a social norm of tax compliance. In this paper we provide an analysis of the effects of information regarding the past degree of tax evasion at the social level on the current individual tax compliance behavior. We build an experiment where subjects declare their income after receiving either a communication of the average tax evasion rate (“official information”) or a private message from a group of randomly matched peers about their tax behavior (“unofficial information”). We use the experimental data to estimate a dynamic econometric model of tax evasion and find three main results. First, tax compliance is very persistent, but less so in the presence of information. Second, the higher the officially communicated past tax evasion rate, the higher the degree of persistence: former evaders are more likely to evade again (and evade more), and former compliant individuals are more likely to comply again (and, when evading, evade less). Third, when an unofficial communication of past evasion (compliance) from all their peers is received, both former evaders and compliant individuals are more likely to evade (comply) again.     

The effects of income source,context, and income level on tax compliance decisions in a dynamic experiment

This study employs a laboratory experiment to explore the joint effect of income source (earned versus endowed) and decision context (tax versus nontax) on tax compliance behavior. During the experiment, subjects faced various income levels and made multiple reporting decisions. The results indicate that overall compliance is not significantly affected by the interaction of income source and context. However, this joint effect influences the relationship between income level and compliance and how compliance behavior evolves over time. In both cases, the treatment group with earned income in a tax context displays behavior that is distinct from the other three groups.     

Can strategic uncertainty help deter tax evasion? An experiment on auditing rules

This paper adds to the economic-psychological research on tax compliance by experimentally testing a simple auditing rule that induces strategic uncertainty among taxpayers. Under this rule, termed the bounded rule, taxpayers are informed of the maximum number of audits by a tax authority, so that the audit probability depends on the joint decisions among the taxpayers. We compare the bounded rule to the widely studied flat-rate rule, where taxpayers are informed that they will be audited with a constant probability. The experimental evidence shows that, as theoretically predicted, the bounded rule induces the same level of compliance as the flat-rate rule when strategic uncertainty is low, and a higher level of compliance when strategic uncertainty is high. The bounded rule also induces distinctive tax evasion dynamics compared to the flat-rate rule. The results suggest that increasing the level of strategic uncertainty among taxpayers could be an effective device to deter tax evasion.     

Compliance costs caused by agency action? Empirical evidence and implications for tax compliance

Compliance costs of taxpayers should not only be affected by the tax law itself but also by its implementation through the tax authorities. In this paper we analyze the effect of authority behavior on the burden of complying with tax regulations. Using survey data of Belgian businesses, we develop an estimation strategy to overcome simultaneity bias by the construction of proxy variables. According to our estimate, a customer-unfriendly tax administration increases the average compliance burden by about 27%. Our outcome has interesting implications for further research. First of all, authority behavior does not only affect “soft” tax compliance factors like fairness and trust, but also “hard” aspects like costs. Second, the distribution of administrative cost burdens between the taxpayer side and the authorities may be important regarding the cost-efficiency of the tax system as a whole.     

Intention to pay taxes or to avoid them: The impact of social value orientation

Economic factors such as audit rates and fines have shown inconsistent effects on tax payments, suggesting that they are not sufficient to explain tax compliance. Moreover, the tax compliance rate is surprisingly higher than what the standard economic model would predict. In the last fifteen years, literature aimed at solving this so called “puzzle of compliance” has increased and pointed out several factors that could possibly explain tax compliance processes, e.g., knowledge of the tax laws, trust toward the political system, as well as personal or social norms. The studies presented here examined the impact of social value orientation on tax morale and intention to avoid/evade taxes. Social value orientation was examined both as a chronic personal orientation (Studies 1 and 2) and as a contextual factor made salient by experimental manipulations (Study 3). The results are supportive of a relationship between social value orientation and measures of tax compliance. Furthermore, results of Study 3 provided evidence for a causal effect of social value orientation on intended tax non-compliance. The effect of social value orientation on intended tax non-compliance was mediated by tax morale (Studies 2 and 3). Results are discussed with reference to their potential practical applications.     

Intrinsic and extrinsic effects on behavioral tax biases in risky investment decisions

Individuals often do not take taxes correctly into account, which results in distorted or unexpected investments. We shed further light on the discussion of such behavioral tax perception biases by analyzing intrinsic and extrinsic effects on investment decisions. We study two dimensions: (1) the influence of emotions and perceived risk (individual dimension, intrinsic effects) and (2) the influence of available tax information by varying tax complexity and salience (tax system dimension, extrinsic effects). In our laboratory experiment, we construct the payoff structure such that the subjects are confronted with exactly the same choices in net terms in a situation with or without a capital gains tax. This design allows us to identify pure tax perception biases. We show that both dimensions are able to explain tax perception biases. In particular, we find evidence that perceived risk is lower and consequently willingness to take risk is higher with a capital gains tax (with full loss offset provision) than without taxation. Furthermore, this positive effect on risky investment is higher in a situation with a rather low level of tax information in which tax complexity is high and tax salience is low.     

Are ‘journalists’ own problems’ aggravating their hostility toward public relations?—A study of Korean journalists

Journalists’ own job problems have been found to be detrimental to media recognition of public relations: journalists vent frustration from their worsening job conditions at public relations practitioners. This outlook of occupational psyche casts a shadow over the bright prospect for media recognition of the profession. Journalists’ problems operate outside media relations, thus beyond direct attempts of public relations practitioners at media recognition via enhancing professionalism in their practices. There have been, however, only a few qualitative studies on this significant issue, all pointing to journalists’ occupational psyche running against media recognition. The purpose of this study is to determine quantitatively whether journalists’ own job satisfaction and their envy of public relations practitioners lead to their negative attitude. A survey of 128 Korean off-line journalists was conducted, and its results suggested that occupational psyche has little influence on media attitude—contrary to the findings of previous qualitative studies. For future study, this paper issues a call for cross-country, comparative research on the subject of journalists’ occupational psyche.     

The influence of tax authorities on the employment of tax practitioners: Empirical evidence from a survey and interview study

Tax practitioners play a crucial role in the degree of taxpayers’ compliance – a role that has increased as tax systems worldwide have become more complex. However, little is known about tax authorities’ impact on taxpayers’ decisions to employ tax practitioners. Based on earlier research on motivations to employ a tax practitioner and the extended slippery slope framework of tax compliance, we conducted two studies which provide some answers. A survey study – comprising a representative sample of 500 Austrian self-employed taxpayers – revealed that financial gain is not the most important reason to employ a tax practitioner but instead the motivation to avoid problems with the tax authorities. Related to that, we also find that taxpayers’ perception of tax authorities wielding coercive power motivates them to employ tax practitioners. In the interview study with 33 self-employed taxpayers and 30 tax auditors, taxpayers indicated that they sought to avoid contact with tax officers by employing tax practitioners. This finding was supported by tax officers who reported preferring interaction with tax practitioners over direct contact with taxpayers. The two studies point to the complex relationship between taxpayers, tax authorities and tax practitioners, and allow the drawing of theoretical and practical implications.     

The slippery slope framework on tax compliance: An attempt to formalization

Kirchler, Hoelzl, and Wahl (2008) presented with the so-called ‘slippery slope’ framework a new approach to understand tax compliance. The slippery slope approach supposes two routes to tax compliance: deterrence of tax evasion by audits and fines on the one hand, and building a trusting relationship with taxpayers by services and support on the other hand. In this paper, the slippery slope framework is formalized by assuming two groups of taxpayers: compliance-minded and evasion-minded persons. Defining reaction functions for persons of both groups with respect to coercive and persuasive power instruments of tax authorities, the typical slippery slope picture emerges that characterises the authorities’ work. As a consequence, both groups of policy tools are considered necessary to generate tax compliance. In addition to that, it is shown that coercive and persuasive power may be substitutes or complements to each other, depending of the parameters of the taxpayers’ reaction functions. As a further crucial determinant of tax compliance, the behaviour of the fellow citizens with respect to taxpaying is identified.
