This study empirically investigates the effects of attitudes toward tax compliance, descriptive norms, injunctive norms, subjective norms, personal norms, tax compliance intention, financial performance, and mental accounting on tax compliance. The determinant are largely developed based on the Theory of Planned Behavior (TPB) and social norms. Data collection is carried out through field surveys to obtain a final sample of 209 respondents who are SME owners in 11 regencies/cities in Central Java Province, Indonesia. The data were analyzed using structural equation modeling (SEM). The results show that attitudes toward tax compliance, injunctive norms, subjective norms, personal norms, and financial performance positively affect SME owners’ tax compliance intentions. Furthermore, financial performance and tax compliance intentions have a positive effect on tax compliance behavior. However, we do not find empirical evidence that mental accounting has a role in strengthening the effect of tax compliance intentions on tax compliance behavior. This study contributes to the tax compliance literature through a more comprehensive measure of subjective norms and the use of financial performance as an alternative measure of perceived behavioral control.
