The purpose of this study is to investigate factors that affect tax auditors’ performance, including the moderating role of work environment. The saturated sampling technique was employed as a sampling technique. Of the 166 tax auditors of the Directorate General of Taxes (DGT) in Riau Region as respondents, 132 questionnaires were returned, fulfilled the requirements, and were complete. Multiple regression analysis was used to test the first, second, and third hypotheses. However, moderated regression analysis was used for the fourth, fifth, and sixth hypotheses testing. The multiple regression analysis results showed that organizational commitment and job satisfaction have a positive effect on the tax auditors’ performance with a p-value for each 0.014 and 0.006. This indicates that the higher the organizational commitment and job satisfaction of the tax auditors, the better their performance. Meanwhile, job stress was found to have a negative effect on the tax auditors’ performance (p-value is 0.006); therefore, the higher the job stresses, the lower the performance. The results also found that work environment as a pure moderator strengthens the effect of organizational commitment on tax auditors’ performance (p-values of Z and X1Z each are 0.279 and 0.000). Meanwhile, work environment as a quasi-moderator also strengthens the effect of job satisfaction with p-values of Z 0.000 and X2Z 0.580. Work environment also moderates and strengthens the effect of job stress on the tax auditors’ performance with p-values of Z 0.000 and X3Z 0.597.

Taxes are the most significant contributor to the Indonesian budget; therefore, increasing taxpayer compliance is crucial for achieving tax revenue realization. This study aims to investigate the role of tax incentives and motivational postures in increasing taxpayer compliance. The analysis was conducted in Pekanbaru, Riau, Indonesia, and the sample consisted of MSME taxpayers registered at the Pekanbaru Tax Service Office. Purposive sampling was utilized to collect data, and of the 384 returned questionnaires, 254 were used for statistical analysis. Multiple regression analysis was utilized to examine the impact of tax incentives on taxpayer compliance, and moderated regression analysis was applied to test the moderating role of motivational postures. The findings showed that the p-values of the first and second hypotheses were 0.00 and 0.001 (0.05, with a positive β value), and the third hypothesis had 0.001 (< 0.05, with a negative β value). This result indicates that the first, second, and third hypotheses are accepted, which means that the more taxpayers feel that tax incentives are beneficial, the greater their compliance with their tax responsibilities. Additionally, tax incentives significantly raise taxpayer compliance when they have a positive motivational posture and decrease it if they have a negative one. The implications of this study influence tax authorities to incentivize taxpayers to increase compliance. Knowledge of the taxpayer’s motivational postures will make it easier for tax authorities to manage taxpayer behavior to increase taxpayer compliance.

This study aims to investigate the effects of professionalism, competence, and role conflict on the tax auditors’ performance. This study also needs to investigate the moderating role of locus of control. The sample consists of 139 tax auditors at the Riau Directorate General Taxes Office-Indonesia. Data analysis techniques include multiple regression and moderated regression analysis. The results show that professionalism, competence, and role conflict affect the tax auditors’ performance. A tax auditor who is professional, has competence, and does not feel there is conflict in carrying out his/her role, will have better performance. Besides, this study also found out that locus of control moderates the effects of professionalism, competence, and role conflict on the tax auditors’ performance. Internal locus of control will further enhance the tax auditors’ performance with high professionalism, satisfactory competence, and reduce low performance resulting from role conflict. Internal locus of control will improve the performance, which decreases due to the occurrence of role conflict with the tax auditors.
