This study aims to examine the effects of self-efficacy, role conflict, and work attitude on employee performance at the Binjai Primary Tax Office. The research employs a quantitative design with a cross-sectional approach. Data were collected from 76 employees using a total sampling technique and analyzed through multiple linear regression with the assistance of SPSS. The results indicate that self-efficacy has a positive and significant effect on employee performance (t = 4.854; p < 0.05), while work attitude also has a positive and significant effect (t = 2.406; p < 0.05). In contrast, role conflict does not have a significant effect on employee performance (t = 0.432; p > 0.05). Simultaneously, self-efficacy, role conflict, and work attitude significantly influence employee performance (F = 30.899; p < 0.05). The coefficient of determination (Adjusted R² = 0.563) shows that 56.3% of the variance in employee performance is explained by these variables. The findings emphasize the importance of strengthening employees’ self-efficacy and fostering positive work attitudes to enhance performance. Meanwhile, the effect of role conflict appears to be context-dependent, influenced by organizational conditions and individual adaptability.
