This paper reports on a laboratory experiment designed specifically to test the influence of national pride on tax honesty while using a physiological marker to observe emotional responses to patriotic priming. Participants were exposed to one of three framing videos before earning income in a real effort task, and at each of 20 rounds (years) were given the chance to declare their taxable income. We find that psychological priming through exposure to symbols of Australian national pride and national identity had a positive effect on the level of tax compliance among Australian but not non- Australians. In addition, non-Australians report lower tax compliance ratios in the treatment groups than in the control group which may indicate an outgroup effect. When exploring the potential of a physiological marker of national pride we observe two different types of physiological responses to the activation and effects of national pride and its impact on tax compliance among Australians. Iconic images activate the parasympathetic nervous system while sports scenes activate the sympathetic nervous system, but both types of images and responses are positively associated with tax compliance. In addition, we find that non-Australians resident in the country for more than a year report a higher level of tax compliance, and that there are some similarities in heart rate variability (HRV) responses between Australian citizens born in the country and those born overseas who have been in Australia for a longer period. Overall, the results support the proposition that identifying with an ingroup at a national level is important for tax compliance.

The ability of a tax authority to collect taxes successfully depends on both its relationship with taxpayers and how strongly these taxpayers are committed to contributing to the common good. We present field and laboratory experimental evidence on a new non-intrusive approach aimed at fostering the commitment to pay taxes. Using a between-subject design in a unique field setting, we analyze whether tax compliance changes if taxpayers receive an offer to promise paying their taxes on time. Taxpayers who complied with the promise entered into a lottery with the chance of winning either a financial or a non-financial reward. Rewards were also offered in response to compliance only (i.e., without being asked to make a formal promise) allowing us to disentangle a pure reward effect from the commitment effect. As potential legal obstacles prevented us from developing a treatment that allowed for identifying whether the promise itself changes behavior, we designed and conducted a laboratory experiment to test this proposition. In the field experiment, taxpayers with a history of being compliant are more likely to make a promise. Similarly, the laboratory experiment indicates that individuals with higher tax morale are more compliant and more likely to make the promise. In addition, for all promise schemes, compliance is significantly higher for the promise-makers as compared to subjects in the control group and to those who did not make a promise. The field experiment indicates that commitment can improve payment behavior. This effect, however, is strongly dependent on the type of reward to which the promise is linked. Compliance increases only if the reward is non-financial. A no compliance effect is observed if cash is offered in return for promise fulfilment. A strong compliance effect for pure non-financial rewards was also obtained in the laboratory experiment.

The ability of a tax authority to successfully collect taxes depends critically on both its relationship with the taxpayers and how strongly these taxpayers are committed to contributing to the common good. We present evidence on a new non-intrusive approach aimed at fostering the commitment to pay taxes. Using a between-subject design in a unique field setting, we experimentally test whether tax compliance can be increased by linking a voluntary promise of timely payment to a reward. We measure the change induced by an additional compliance promise through identifying the pure reward effect. We find that although previously compliant taxpayers are more likely to make a promise, the commitment to do so can improve payment behaviour. This effect, however, is strongly dependent on the type of reward to which the promise is linked. Compliance only increases when the reward is non-financial. No compliance effect is observed if cash is offered in return for promise fulfilment.

Although tax non-filing and the resulting tax evasion are a challenge to public welfare of developing countries, scholarly knowledge on the subject is minimal. The present paper compares rich self- employed identified as non-filers with a randomized group of tax filers in terms of two bases of perceived tax system legitimacy: knowledge of taxpayers' rights and perceived corruption. The results indicate that both factors relate to tax non-filing and moreover, that perceived service orientation of the tax administration, which reduces citizens' ignorance of tax rights and doubts about authorities' correct behaviour might foster perceived legitimacy and in turn increase tax compliance.

Historically, tax compliance has been a highly interdisciplinary avenue of research to which economics, psychology, law, sociology, history, political science, and accountancy have made valuable contributions. It is less well understood, however, whether we can glean useful insights into tax compliance by moving beyond the social sciences. In particular, the literature pays little attention to the relevance of biology. This paper attempts to remedy this shortcoming by examining the potential opportunities and limitations of introducing biological concepts into tax compliance research.

We conduct a field experiment on tax compliance, focusing on newly founded firms. As a novelty the effect of tax authorities’ supervision on timely tax payments is examined. Interestingly, results show no positive overall effect of close supervision on tax compliance., Highlights • We study the impact of supervision on tax compliance with a field experiment. • We manipulate supervision through friendly deterrence. • Results suggest that supervision leads to delayed tax payments. • It is concluded that supervision causes a crowding out of intrinsic tax compliance.

Field experiments in the area of tax compliance are rare. This field experiment generates a unique data set with respect to individuals' under-declaration of income and wealth and over-deductions of tax credits by obtaining exclusive full access to the audits. Using this commune level data from Switzerland, the paper explores the influence of moral suasion on tax compliance. Moral suasion was introduced through a treatment in which taxpayers received a letter signed by the commune's fiscal commissioner containing normative appeals. Interestingly, I observe differences between under-declaration and over-deductions. Moreover, the overall finding is in line with former results that moral suasion has hardly any effect on taxpayers' compliance.

Although paying taxes is a key element in a well-functioning civilized society, the understanding of why people pay taxes is still limited. What current evidence shows is that, given relatively low audit probabilities and penalties in case of tax evasion, compliance levels are higher than would be predicted by traditional economics-of-crime models. Models emphasizing that taxpayers make strategic, financially motivated compliance decisions, seemingly assume an overly restrictive view of human nature. Law abidance may be more accurately explained by social norms, a concept that has gained growing importance as a facet in better understanding the tax compliance puzzle. This study analyzes the relation between psychic cost arising from breaking social norms and tax compliance using a heart rate variability (HRV) measure that captures the psychobiological or neural equivalents of psychic costs (e.g., feelings of guilt or shame) that may arise from the contemplation of real or imagined actions and produce immediate consequential physiologic discomfort. Specifically, this nonintrusive HRV measurement method obtains information on activity in two branches of the autonomous nervous system (ANS), the excitatory sympathetic nervous system and the inhibitory parasympathetic system. Using time-frequency analysis of the (interpolated) heart rate signal, it identifies the level of activity (power) at different velocities of change (frequencies), whose LF (low frequency) to HF (high frequency band) ratio can be used as an index of sympathovagal balance or psychic stress. Our results, based on a large set of observations in a laboratory setting, provide empirical evidence of a positive correlation between psychic stress and tax compliance and thus underscore the importance of moral sentiment in the tax compliance context.

Policymakers often propose strict enforcement strategies to fight the shadow economy and to increase tax morale. However, there is also a bottom-up approach such as, for example, decentralizing the political power to those who are close to the problems. Thus, this paper analyses the relationship between local autonomy and tax morale or the size of the shadow economy. We use data on tax morale at the individual level and macro data of the size of the shadow economy to systematically analyse the relevance of local autonomy and compliance in Switzerland, a country where the degree of federalism varies across different cantons. The findings suggest that there is a positive (negative) relationship between local autonomy and tax morale (size of the shadow economy).

Many taxpayers truthfully declare their income to the tax administration. Why? In this paper we have found a significant correlation between tax morale and tax evasion, controlling a variety of factors. Furthermore we have analysed tax morale as dependent variable and studied the determinants that shape it. The results indicate that factors such as the tax administration, tax system, tax awareness, compliance perceptions, trust in officials and others, and the willingness to obey have a relatively strong impact on tax morale.

Taxpayers are more compliant than the traditional economic models predict. Why? The literature calls it the "puzzle of tax compliance". In this paper we use field, experimental and survey data to investigate the empirical evidence on whether presence of tax morale helps to resolve this puzzle. The results reveal a strong correlation between tax morale and tax evasion/compliance which confirms the value of taking the research a step further by looking at the determinants of tax morale. We explore this question with a particular focus on the importance of governance quality.

In recent years the topics of illegal activities such as corruption or tax evasion have attracted a great deal of attention. However, there is still a lack of substantial empirical evidence about the determinants of compliance. The aim of this paper is to investigate empirically whether women are more willing to be compliant than men and whether we observe (among women and in general) differences in attitudes among similar age groups in different time periods (cohort effect) or changing attitudes of the same cohorts over time (age effect) using data from eight Western European countries from the World Values Survey and the European Values Survey that span the period from 1981 to 1999. The results reveal higher willingness to comply among women and an age rather than a cohort effect.

Considerable evidence suggests that enforcement efforts cannot fully explain the high degree of tax compliance. To resolve this puzzle of tax compliance several researchers have argued that citizens’ attitudes toward paying taxes defined as tax morale helps to explain the high degree of tax compliance. However, most studies have treated tax morale as a black box without discussing which factors shape it. Additionally, the tax compliance literature provides little empirical research that investigates attitudes toward paying taxes in Europe. Thus, this paper is unique in its examination of citizen tax morale within three multicultural European countries, Switzerland, Belgium and Spain, a choice that allows far more detailed examination of the impact of culture and institutions using datasets from the World Values Survey and the European Values Survey.

This paper analyzes the impact of rewards on tax compliance as an additional instrument to take into account. While social psychologists and neuroscientists have emphasized the importance of rewards, the tax compliance literature has strongly disregarded the possibilities of rewards. The use of field experiments presents an alternative ?carrot? strategy for tax policy. Design mechanisms to conduct a field experiments focusing on the impact of rewards on tax compliance are discussed.

This paper examines citizens' attitudes toward paying taxes - what is sometimes termed their "tax morale", or the intrinsic motivation to pay taxes - focusing on the experience of individuals in the Russian Federation. A unique aspect of our analysis is our ability to study tax morale before (1991), during (1995), and shortly after (1999) the transition of the Russian economy from a centrally planned economy to one based on market reliance. Our empirical analysis uses data from the World Values Survey and the European Values Survey. The results show decay in tax morale in the first four years of the transition from 1991 to 1995, and a small recovery in 1999. These results are consistent with the relevance of social norms in tax compliance, where the widespread perception of tax evasion and of a corrupt and inefficient state led initially to a decline of tax morale. However, the results also suggest that the restoration of a higher level of trust in the state, after some progress in the transition to a market economy, positively influenced tax morale. Using disaggregated data for Russian regions, we also find significant regional differences in tax morale, reflecting the degree of trust different regions have toward Moscow's institutions and policies.

There is considerable evidence that enforcement efforts cannot fully explain the high degree of tax compliance. To resolve this puzzle of tax compliance, many researchers have argued that citizens' attitudes toward paying taxes or tax morale, seen as the intrinsic motivation to pay taxes, can help to explain the high degree of tax compliance. However, most studies treat tax morale as a black box without discussing which factors shape it. Additionally, there is a lack of empirical evidence in the tax compliance literature that investigate attitudes towards paying taxes in Europe. Thus, a unique aspect in this paper is to examine citizens' attitudes towards paying taxes in the three European countries Switzerland, Belgium and Spain, allowing thus to investigate in detailed way the impact of internal and external institutions.

This paper analyses fiscal autonomy in Germany. First, it provides an overview of fiscal autonomy. What is novel in this paper compared to previous studies is the development of a fiscal autonomy coefficient for the states, based on communal data. The basic intention in the empirical part is to analyse how fiscal autonomy affects tax morale, defined as the intrinsic motivation to pay taxes, in Germany. Strong evidence has been found that a higher fiscal autonomy leads to a higher tax morale, controlling in a multivariate analysis for additional factors. Thus, this paper fills a gap in the tax compliance literature, which has rarely analysed the impact of fiscal autonomy on compliance

ax morale has received a growing attention in academics as well as in public life. The relevance of tax morale for fiscal policy cannot be neglected as tax morale can help to explain the level of tax compliance or tax evasion. This paper gives an overview of tax morale with a special focus on Switzerland. We highlight the magnitude and the de-terminants of tax morale that have been isolated so far and discuss directions for future research in this area. In particular, we concentrate on fiscal policy implications.

Why so many people pay their taxes, although fines and audit probability are low, has become a central question in the tax compliance literature. Concepts of Homo Economicus, endowed with a more refined motivation structure, help to shed light on the tax compliance puzzle. This paper provides empirical evidence for the relevance of conditional cooperation, using survey data from 30 European countries. The findings suggest that a higher perceived tax evasion leads to a lower tax morale, also when controlling for additional factors in a multivariate analysis.

In recent years much research has investigated whether values, social norms, and attitudes differ across countries and whether these differences have measurable effects on economic behavior. One area in which such studies are particularly relevant is tax compliance, given both the noted differences across countries in their levels of tax compliance and the marked inability of standard economic models of taxpayer compliance to explain these differences. In the face of these difficulties, many researchers have suggested that the intrinsic motivation for individuals to pay taxes - what is sometimes termed their "tax morale" - differs across countries. However, isolating the reasons for these differences in tax morale is notoriously difficult. In a common approach, studies sometimes referred to as "cultural studies" have often relied upon controlled laboratory experiments conducted in different countries because such experiments can be set up with identical experimental protocols to allow cultural effects to be isolated. In this paper we first analyze a cross-section of individuals in Spain and the United States using the World Values Survey (WVS). In line with previous experiments, our findings indicate a significantly higher tax morale in the United States than in Spain, controlling in a multivariate analysis for additional variables. We then extend our multivariate analysis to include 14 European countries in the estimations. Our results again indicate that the United States has the highest tax morale across all countries, followed by Austria and Switzerland. We also find a strong negative correlation between the size of shadow economy and the degree of tax morale in those countries.

Why citizens pay their taxes voluntarily is an important question for tax administrations worldwide. Some believe it is because taxpayers are deterred from tax evasion out of a fear of being caught or penalised. Others, in contrast, suggest that factors such as the level of tax morale one has (i.e., the intrinsic motivation one has to pay their tax) affects compliance behaviour. While there have been numerous empirical studies published that have explored the role of deterrence on tax compliance behaviour, very few studies have explored the concept of tax morale in any detail. This study therefore attempts to rectify this gap in the literature. If tax morale is important in determining compliance behaviour, as several researchers have suggested, then it is also important to understand what might affect one's level of tax morale. The specific aim of this paper will be to identify factors that shape or have an impact on tax morale. Using data collected from the Australian wave of the 1981 and 1995 World Values Survey, this study will demonstrate that factors such as trust and moral beliefs play an important role in shaping tax morale in Australia. Further, it will be shown that tax morale has increased significantly in Australia since the early 1980s, and that it has done so at a faster rate than many other OECD countries. Possible explanations for this increase will be discussed.

There is considerable evidence that enforcement efforts can increase tax compliance. However, there must be other forces at work because observed compliance levels cannot be fully explained by the level of enforcement actions typical of most tax authorities. Further, there are observed differences, not related to enforcement effort, in the levels of compliance across countries and cultures. To fully understand differences in compliance behavior across cultures one needs to understand differences in tax administration and citizen attitudes toward governments. The working hypothesis is that cross-cultural differences in behavior have foundations in these institutions. Tax compliance is a complex behavioral issue and its investigation requires the use of a variety of methods and data sources. Results from laboratory experiments conducted in different countries demonstrate that observed differences in tax compliance levels can be explained by differences in the fairness of tax administration, in the perceived fiscal exchange, and in the overall attitude towards the respective governments. These experimental results are shown to be robust by replicating them for the same countries using survey response measures of "tax morale."

The intention of this paper is to analyse how audit courts affect tax morale, controlling in a multivariate analysis for a broad variety of potential factors. Switzerland with its variety of audit court competences among the cantons has been analysed. With data from the ISSP for 1999 evidence has been found that a higher audit court competence has a significantly positive effect on tax morale. Thus, the results in Switzerland suggest that in the cantons where audits courts are not just knights without swords or toothless tigers, they help improve taxpayers' tax morale and thus citizens' intrinsic motivation to pay taxes.

There is considerable evidence that enforcement efforts cannot fully explain the high degree of tax compliance. Previous studies have found differences in compliance behaviour across cultures. Novel in this paper is to investigate the impact of culture differences within a country rather than between countries. Thus, the main purpose of the paper is to see how culture affects tax morale, using World Values Survey (WVS) and European Values Survey (EVS) data. The empirical findings focus individually on Switzerland, Belgium and Spain, countries with a certain cultural variety. In general, the results indicate that the cultural background seems not to have a strong effect on tax morale within a country. However, there is evidence that there is a strong interaction between culture and institutions, which has a strong impact on tax morale.

This paper analyses the impact of direct democracy, trust in government, the court and the legal system, and federalism on tax morale. In the tax compliance literature it is novel to analyse tax morale as dependent variable and to systematically analyse the effects of formal and informal institutions in Switzerland, a country where participation rights and the degree of federalism vary across different cantons. We used two different data sets at the individual level (World Values Survey and International Social Survey Programme). The findings suggest that direct democratic rights, local autonomy, and trust in government, the court and the legal system have a significantly positive effect on tax morale.

The intention of this paper is to analyze religiosity as a factor that potentially affects tax morale. For this purpose, a multivariate analysis has been done with data from the World Values Survey 1995- 1997, covering more than thirty countries at the individual level. Several variables, such as church attendance, religious education, being an active member of a church or a religious organization, perceived religiosity, religious guidance and trust in the church have been analyzed. The results suggest that religiosity raises tax morale.

Why so many people pay their taxes, even though fines and audit probability are low, is a central question in the tax compliance literature. Positing a homo oeconomicus having a refined motivation structure sheds light on this puzzle. This paper provides empirical evidence for the relevance of conditional cooperation, using survey data from 30 West and East European countries. We find a high correlation between perceived tax evasion and tax morale. The results remain robust after exploiting endogeneity and conducting several robustness tests. We also observe a strong positive correlation between institutional quality and tax mmorale. Keywords: Tax morale; Tax compliance; Tax evasion; Pro-social behavior; Institutions
