Tax Ethics and Tax Evasion, Evidence from Greece

Tax evasion involves the deliberate act of noncompliance to tax legislation and the disregard of tax payments from the citizens. Moreover, many citizens do not directly violate tax legislation, but avoid paying taxes by taking advantage the lack of explicit legislation. Along those lines, tax ethics forms a personal constraint which regulates the way citizens behave regarding the payment of taxes. The purpose of this paper is to explore the tax ethics of Greek citizens and to compare them with those of other countries. In order to compare our results with those of other countries, we used a questionnaire, developed by Prof. Robert W. McGee, which has been used as a research instrument in similar studies. Our results show that Greek citizens do not evade taxes due to potential personal gains but rather because they believe that the state is incapable of proper allocation of public money and that the current political and tax system is inefficient or corrupt. In conclusion, the state has to gain the trust of its citizens in order to increase tax ethics and tackle tax evasion, by allocating its resources efficiently and by promoting political transparency.


Introduction
Withholding information regarding one's income in order to pay less tax has moral and legal implications [1].The state needs sources of income, in order to be able to offer services and provide security to its citizens.On the other hand, the government frequently wastes public money due to inefficient management and sometimes due to illegal abuse.Consequently, citizens deviate from the legal Since 2008, in the light of the economic crisis, more strict measures have been taken regarding the detection of "concealed" income [2].In this scope, governing practices regarding tax revenue collection have been developed in the European Union (EU).Moreover, exchange of information regarding "concealed" income is also promoted between member states and countries such as Switzerland, Monaco, San Marino and Liechtenstein [3].During the last years, the European Parliament has greatly contributed on the implementation of initiatives regarding the mitigation of tax evasion and money laundering from illegal activities [4].As a result, governments in the EU have enacted and enforced more sophisticated legislation against tax evasion.Greece has a very strict legal system.
However, the current "overregulation" often results in contradictions between various laws and law complexity, which enhances tax evasion.At the same time, there is a significant decrease in VAT revenue in Greece, compared to the rest of the European Union.
The aim of this paper is to explore the issue of tax ethics and tax evasion in order to identify in which situations tax evasion is accepted as ethical and which social groups consider tax evasion to be more acceptable.Moreover, we will analyze the tax ethics of Greek citizens and compare it to that of citizens from other countries.Regarding the contribution of our paper to academic research, we will use Robert McGee's questionnaire to measure tax evasion and tax ethics of Greek citizens.To our knowledge, no other research has been conducted having used an internationally recognized research tool to compare Greece to other countries and identify the characteristics of citizens which make them justify tax evasion.
The paper is structured as follows: first, the concepts of tax ethics and tax evasion are presented and a literature review is conducted.Next, we introduce the research methodology and present the research questions as well as the measurement instrument.Then the results of the empirical survey are presented.
The paper concludes with the main conclusions, limitations and proposals for future research.

Conceptual Framework
Tax ethics refers to the tax payer's moral obligation to pay taxes and is affected by the relationship between the tax payer, as a citizen, and the government.Tax ethics and tax evasion are often used interchangeably.Tax evasion, however, refers to a person actively trying to avoid paying tax [5] while tax ethics refers to all non-monetary incentives to comply with tax legislation [6].Measuring tax ethics helps to indirectly measure the size of "shadow economy", since not many individuals are willing to reveal whether they have committed financial irregularities or not.Consequently, a higher degree of tax ethics is positively related to regular tax payments and compliance to tax regulations.On the contrary, indi-

Literature Review
The attitude of citizens towards tax obligations is affected by various factors [6].
For example, several studies show that tax ethics is higher among older citizens, citizens who have strong religious beliefs or citizens who trust politicians.
Moreover, international research has shown that tax ethics is positively related to tax system fairness and government transparency and negatively related to tax evasion and shadow economy [5].
In Portugal, a survey conducted by the European Values Study during the period 2008 to 2010 showed that behavioral, psychological and political factors have a direct impact on tax ethics.Fairness in the democratic political system and citizens' personal satisfaction with the system has a direct influence on tax ethics.Alternatively, citizens who believe that their political system is good have stronger tax ethics.On the other hand, there is a negative relationship between tax ethics, political participation and mistrust, i.e. citizens who are actively involved in politics and who do not trust others have weaker tax ethics [8].In Turkey, trust in the state, religion, and national pride are positively related to compliance to social requirements such as tax payment.In other words, Turkish citizens who feel confident of social norms have a high level of tax ethics compared to those who do not [9].
In Spain, unlike Turkey, trust in the political system and religion do not have an effect on tax ethics.Nevertheless, national pride and a higher level of education have a positive impact on tax ethics [9].In Russia, the World Value Survey In Pakistan, survey results show that women have significantly higher tax ethics than men.Similarly, pensioners comply more with tax legislation than non-pensioners while self-employed citizens have weaker tax ethics [10].In Mauritania, similar to other surveys, married citizens and the elderly comply more with tax legislation compared to younger citizens.Moreover, justice, confidence in the government, and perceived fairness of how public money is spent improve the willingness of taxpayers to comply with tax requirements.Along those lines, tax compliance increases when citizens believe that the tax and legal system are fair, clear and stable, and corruption is being effectively tackled [11].
In Latvia, legitimacy of the tax authorities and the government, national pride and perception of the danger and severity of punishment were found to be positively related to high tax ethics for business owners and managers [12].
Finally, in a recent survey, in which data was collected from 35 Eurasian countries, tax ethics is higher in rich countries, in countries which have increased public revenues and expenditures, in countries with a fair and clear legal system and in countries with a low level of social inequality and corruption.
Moreover, citizens of higher education and citizens with children have a higher sense of tax compliance [13].

Research Methodology
The purpose of this paper is to examine the perceptions of Greek taxpayers regarding tax evasion and to explore the circumstances under which tax evasion is accepted or considered acceptable.Moreover, we will compare the results of our survey with those of other countries and highlight the differences between the tax ethics of Greek citizens and those of citizens of other countries.A quantitative approach methodology was selected for this study.The participants were contacted via social media and email and were requested to answer an online questionnaire.The questionnaire used in this paper has been developed by Professor McGee and has been used as a research tool in various studies ( [1] [14]- [22]).The questionnaire is still used in academic research [23].In the first part of the questionnaire, participants were asked to respond to questions regarding demographic characteristics such as gender, occupational status, and level of education, marital and financial status.Then, they were asked to express their level of agreement/ disagreement to statements regarding tax evasion at a seven-step Likert type scale.The scale was rated as: 1-absolutely agree, 2-agree,

Demographic Characteristics
A total of 500 questionnaires were sent via email and social media and 305 complete questionnaires were received representing a response rate of 61.00%.To increase response rate three reminders were sent to each target respondent.The first was after one week from the initial email posting, the second after two weeks from the initial posting and the third after four weeks from the initial email posting.financial situation, the majority reported an annual income between € 10,000 and € 30,000 per year (57.7%), followed by those who have a low income of up to € 10,000 per year (29.2%), while about 10% reported an annual income of more than € 30,000 per year.Finally, regarding the marital status, 59.3% were married and 36.7% were unmarried.

Results of Descriptive Statistics
The mean values of the survey items are presented below ( the relationship between tax ethics and whether the respondent approves or disapproves a potential public funded project, have received similar rating on average.This means that Greek citizens do not link tax ethics with their own personal beliefs regarding the use of public money, as long as it is not wasted or abused.This is also supported by the mean values of items V08 and V09, which examine the relationship between tax ethics and the respondent's personal gains from the implantation of public projects.We both items have received high mean values which furthers strengthens our claim that Greek citizens do not evade taxes due to potential personal gains but rather because they believe that the state is incapable of proper allocation of public money.
Finally, regarding the role of tax collection agencies, we observe that item V12, which corresponds to the relationship between tax evasion and tax audit, has also a very high mean value.This finding is particularly interesting because it shows that tax ethics is not necessarily affected by the severity of tax control, since most respondents believe that tax evasion is unethical despite the low chance of "being caught".

Comparison with Other Countries
This research was based on a questionnaire developed by Prof. Robert W.
McGee, which has been used as a research instrument in similar studies.Table 3 presents the results of similar surveys that have been conducted in 8 different countries.
Compared to other countries, Greek citizens have less tolerance on tax evasion, with an average of 5.16, while the average of rest of the countries is 5.04.
The country with the weakest tax ethics is Romania with an average of 4.59, while the country with the highest tax ethics appears to be Hong Kong, although data regarding the questions related to state discrimination are not provided.
Taking into account all the items of the questionnaire, Guatemala is the country with the highest tax ethics rate.The question that has received the lowest ranking in all countries is the one related to corrupted politicians and abuse of public money.On the other hand, items V02 and V05 present the highest mean values in all countries, which means that tax ethics is positively affected by justice and efficiency in the tax system and proper allocation of public money.
Our results are in accordance to those of similar studies.In an empirical study by [24] regarding tax evasion, taxpayers' perceptions about the integrity of government officials, accountability and transparency have a significant impact on tax ethics.The same results are observed by [25], who also state that taxpayers are more likely to be consistent with their tax obligations if they believe that the government manages public money in an efficient and transparent manner.Regarding our research results, citizens are willing to pay more taxes if they believe that the government is using public money to enhance social welfare by financing projects that are beneficial not necessarily to the respondent himself but at least to the rest of the citizens.If this relationship is not clear, taxpayers are less likely to be consistent with their tax obligations, since they believe that their contribution to general prosperity does not benefit either themselves or their fellow citizens, but it is wasted through mismanagement and corruption [26].

Conclusions
Tax evasion is an economic and social phenomenon that has always been in the centre of public policy.Taxpayers commit tax evasion when they belief that public money is not allocated efficiently from the government to the citizens.Consequently, transparency is of outmost importance to taxpayers in order for them to believe that their contribution to public income is important and necessary.
Therefore, it is very important for the state to have a legal framework that holds politicians accountable for their decisions and actions regarding the management of public money.Rebuilding the trust between the government and the citizens is perhaps the only solution to tackle tax evasion and this is where the current political system should focus its efforts on.
Comparing the results of our study with those of similar studies in other countries, we observe that there are no significant differences in the way tax ethics is being perceived by the citizens.Perhaps the only noticeable difference between Greece and the majority of the other countries analyzed in the present study is the fact that tax ethics receives higher mean values in all the questions regarding discrimination, which means that Greek citizens do not associate tax obligations with human rights and how the government interacts with citizens from different countries.
The current research instrument has been used to measure tax ethics is Greece for the first.We propose that further research should be conducted in order to make generalizations about this study's subject.The main constraint and limitation of the current research is the bias of the survey respondents.Future research should focus on a qualitative approach to understand the underlying factors that lead citizens to tax evasion.For example, in-depth interviews of different population groups could contribute into further understanding how tax evasion manifests itself in different social contexts.
