The data was collected from the audited financial report of the federal board of Inland Revenue covering the period of 2012 to 2022. The collected data were analyzed using descriptive statistics, correlation analysis, and Generalized Least Squares (GLS) estimation techniques are employed to analyze data from 160 observations. From the results of the findings, the study revealed the significant positive effects of tax revenue from indirect taxes, corporate taxes, and non-tax revenue from fees and fines on budget implementation. However, tax revenue from direct taxes unexpectedly exhibits a negative effect in the model analyzing non-tax revenue.
