ABSTRACT

The main objective of this study is to explore the relationship between tax revenue in Nigeria and her economic growth using the Ex-post facto research design. Time series data covering the independent variable – tax revenue, (proxied by Custom and Excise Duty (CED), Petroleum Profit Tax (PPT), Company Income Tax (CIT), Value Added Tax (VAT), and capital gains tax (CGT) and the dependent variable – economic growth (proxied by the gross domestic product (GDP)) for a period of twenty (10) years (2013 to 2022) were applied in carrying out this research work. Multiple Linear Regression analysis was used to analyze the data by employing the use of Vector Error Correction Model. The findings reveal that Custom and Excise Duty revenue has a significant and negative effect on economic growth in Nigeria (p-value = 0.0013), Petroleum Profit Tax revenue has a significant and negative effect on economic growth in Nigeria (p-value = 0.0004), Company Income Tax revenue has a significant and positive effect on economic growth in Nigeria (p-value = 0.0012); Value added tax revenue has a significant and positive effect on economic growth in Nigeria (p-value = 0.0000); Capital gains tax revenue has no significant and negative effect on economic growth in Nigeria (p-value = 0.5327); We recommend among others that the government should consider reducing the rate of custom and excise duty on imports and exports, in order to reduce the negative effects on economic growth
