This study examines the associations of monitoring, discipline, and service quality with tax revenue at the Jakarta Setiabudi Tiga Pratama Tax Office. It responds to the practical need to understand how control-oriented and service-oriented administrative mechanisms may operate together in supporting revenue performance. A quantitative explanatory survey was conducted with a reported sample of 80 respondents drawn from a population of 410 through the Taro Yamane formula and simple random sampling. Questionnaire data were analysed using IBM SPSS Statistics 27, multiple linear regression, individual t-tests, an overall F-test, and the coefficient of determination. The reported bivariate results show statistically significant positive associations between tax revenue and monitoring (beta = .503, t = 5.767, p < .001), discipline (beta = .870, t = 15.601, p < .001), and service quality (beta = .766, t = 10.514, p < .001). The joint model was also statistically significant (F = 14.574, p < .001), with R = .559, R-squared = .313, and adjusted R-squared = .291. Thus, the three predictors collectively explained 31.3% of the reported variance in tax revenue. The findings suggest that systematic monitoring, consistent compliance-related discipline, and responsive and reliable services constitute complementary components of tax administration. The study contributes an integrated organisational perspective from a single Indonesian tax office. However, its cross-sectional design supports associational rather than definitive causal conclusions, and the underlying respondent and regression records should be reconciled before submission.
