The Impact of Investors' Behavior on Tax Management Approaches in Tehran Stock Exchange

The purpose of the present study is to review the effect of investors' behavior on tax management approaches. In this research, approaches to tax management including tax evasion, tax avoidance, and tax aggressiveness were studied. To this aim, panel data method based on the annual data obtained from accepted corporations in Tehran Stock Exchange during 2014-2021 were used. Finally, 127 corporations were chosen as the sample by systematic deletion technique and data analysis was done by Stata (version 16/with 95% confidence). To measure sentimental tendency and herding behavior of investors, EMSI index and Huang and Salmon Model (2006) were used. The experimental evidence and results of the research indicate that investors' behavior has a significantly positive effect on tax management approaches. That is to say, with the increase of sentimental and herding behavior among the investors, the directors' tax management in corporations improves. The research results showed that investors' behavioral variables (herding behavior and sentimental tendency) have a direct and positive effect on tax management approaches in corporations. It means that as investors' herding behavior and sentimental tendency increases, tax evasion, tax avoidance and tax aggression goes up, too. Therefore, investors' behavior is confirmed to be an important element to disturb order in financial markets. The results of this research can be effective to improve politicians and investors' decision-making for proper orientation towards the stock market and its consistent management.
