Abstract
The objective of this study was to analyse the influence of tax and non-tax revenue generated by the federal government on the economic growth of Nigeria. The study utilised an ex post facto approach and specifically examined the Nigerian economy as a whole, resulting in a population and sample size of one. Data was collected from secondary sources, including the yearly reports and statistics releases of the CBN and the office of the Federal Inland Revenue Service (FIRS). The study spanned a decade, specifically from 2001 to 2020. The hypotheses were tested using simple linear regression for data analysis. The regression study revealed a substantial influence of federal government tax income on economic growth. The F-statistic yielded a value of 466.0399, the P-Value was determined to be 0.000, and the R-squared value was calculated as 0.962813. These results indicate that about 96.28% of the variability in real GDP can be accounted for by tax revenue. Similarly, the analysis demonstrated a substantial impact of non-tax revenue from the federal government on the growth of the economy. The F-statistic yielded a value of 201.5388, the P-Value was found to be 0.000, and the R-squared value was determined to be 0.918010. These results indicate that about 91.80% of the variance in real GDP can be accounted for by non-tax revenue. Moreover, the economic growth was significantly influenced by the overall revenue of the federal government. The F-statistic yielded a value of 469.5482, indicating a strong statistical significance. The P-value was 0.000, further confirming the significance of the results. The R-squared value was 0.963081, indicating that approximately 96.31% of the fluctuation in real GDP can be accounted for by total tax revenue. These findings emphasise the essential importance of both tax and non-tax revenue, namely from the federal government, in stimulating economic growth. In order to increase revenue generation, it is crucial for the government to give priority to enhancing tax administration and compliance. This can be accomplished by implementing efficient tax regulations, streamlining tax procedures, and establishing strong monitoring and enforcement measures. Furthermore, it is advisable to diversify non-tax revenue streams beyond oil.
