In the field of corporate tax behavior, corporate governance mechanisms are effective for shaping and monitoring the behavior of managers. The board, which is responsible for allocating resources, improving performance and increasing shareholder wealth, plays a central role in choosing a tax management strategy. Hence, companies with different governance structures may adopt different types of tax management. Therefore, it can be argued that corporate governance mechanisms can affect corporate tax activities. In order to achieve the weight of the identified criteria, the network analysis process method was used. The purpose of this method was to structure the decision-making process, according to a scenario affected by multiple independent factors. In this method, there can be a relationship between all levels, while in the method of hierarchical analysis process, this relationship could only be from high levels to low levels. The method of the network analysis process, such as the hierarchical analysis process, calculates the inconsistency of all judgments by the conformity rate, and the calculated inconsistency rate must be less than 10%. The compatibility coefficient of the final matrix shows the validity of the questionnaire. In order to analyze the data, Super Decision 1.6.0 software developed by Thomas L. Saati, the inventor of this method, as well as MS Excel 2019 software were used. There is considerable evidence that increasing tax requirements can increase tax compliance, but typically some types of tax offenses are used as a tool to control the phenomenon of tax default.

Auditors' personality traits have a significant effect on the motivation of their financial behavior. In fact, the personal and personality traits of auditors that can be influenced by the environment play an important role in motivating individuals to engage in financially professional behaviors. Audit team norms are one of the factors in the audit firm environment that affect the auditor's behavior. In this study, the effect of auditing team norms and auditors' personality types on auditor objectivity was investigated. The Entropy technique is used to examine the importance of the norms of the audit team and the personality components of the peers, and based on the results and using the TOPSIS method, these factors affecting the objectivity of financial auditors are ranked. The statistical population of this study includes all professional auditors working in the auditing organization and private auditing institutions, members of the Iranian Society of Certified Public Accountants in 2020, including 242 members. The results showed that extroverted and responsible personality types have a positive and significant effect on auditors' objectivity. The results also showed that the norms of the audit team have a positive and significant effect on the objectivity of auditors.

Tax fraud is the legal minimization of tax liability through appropriate financial planning techniques, which often involve techniques, accounting methods, and fraudulent transactions, and pursue little or no purpose other than creating a tax advantage. There is no doubt that tax fraud is a legal way to reduce the amount of tax, and individuals with different personality traits can take dissimilar procedures to reduce the amount of tax. In this study, the impact of personality traits on tax fraud concerning gender (male and female) and type of firm (listed and non-listed) is investigated. The statistical population of the study includes all financial managers of listed and non-listed firms in 2020 who are not exempt from taxes. Information about personality traits was collected through a questionnaire and SPSS software version 21 was used to test the hypotheses. The results suggest that the personality traits of neuroticism, extraversion, flexibility (openness to experience), and agreement have a positive and significant effect on tax fraud. In contrast, the personality trait of conscientiousness has a negative effect on tax fraud. This effect was also observed in both male and female financial managers. The results also indicate that the effect of personality traits of neuroticism, extraversion, and agreement on tax fraud in the managers of listed firms is positive and the effect of personality traits of flexibility (openness to experience) and conscientious is negative on tax fraud, but the effect of personality trait of neuroticism is negative and the effect of flexibility (openness to experience) on tax fraud in listed firms is not statistically significant. In non-stock firms, personality traits of neuroticism, extraversion, flexibility (openness to experience), and agreement have a positive and significant effect on tax fraud, and the personality trait of conscientiousness has a negative effect on tax fraud.
