This study aims at investigating the relevance of tax revenue in driving economic growth in emerging market economy context. . Using data extracted from central bank of Nigeria statistical bulletin for various years and auto-regression estimation model, our study documents the existence of significant and positive relationship between petroleum profit taxes (PPT), Company Income Tax (CIT) on economic growth in Nigeria. Our findings further reveal that Value Added Tax (VAT) and Custom –excise duty (CED) exert negative influence on economic growth. However, the study provide evidence that VAT and CED are insignificant in determining the economic growth in emerging market economy context with special interest in Nigeria This study provide further evidence that the higher the amount of tax revenue generated, the higher the level of economic growth in the economy. There is a recommendation therefore that strong institutional reforms are panacea to prevent leakages of revenue from VAT and CED.
Nigeria has experienced downward slope in its productivity and economic growth. This affects the macroeconomic environment as it is evident that the country has challenges in fixing their roads, challenging in achieving national plan, high rate of unemployment, low quality education and low standards of living. In all these, studies have implicated low and unsteady revenue generation in the country. This study investigated petroleum profit tax volatility on economic growth in Nigeria, using inflation and exchange rates as moderating variables. This study adopted ex post facto research design. Data were obtained from certified sources; namely, National Bureau of Statistics, Central Bank of Nigeria Statistical Bulletin and Federal Inland Revenue Services for the 1981Q1-2017Q4, amounting to one hundred and eight (108) observations. Data were exposed to the scrutiny of the appropriate regulatory agencies for validity and reliability. Pre-estimation tests were conducted using Pearson correlation and stationarity tests. The post-estimation tests included linearity, Heteroskedasticity, Breusch-Godfrey serial Correlation Lagrangian Multiplier and stability test. Data were analyzed using both descriptive and inferential statistics. Findings revealed that Petroleum profit tax volatility had positive and significant effect on EG in Nigeria (R2 = 0.56, β1 = 0.422, t(107) = 6.927, p<0.05). This study concluded that Petroleum profit tax volatility affects economic growth in Nigeria. It was recommended that government should formulate tax policies that will encourage steady tax revenue. In addition, government should ensure prudent application of tax fund to the development of infrastructure that would translate into economic growth
The study examines the effect of petroleum profit tax on economic growth of Nigeria. Income from petroleum taxes is the proxy for PPT while economic growth was measured using Gross Domestic Product (GDP). The research adopted expos-facto research as secondary data were used for the analysis. Data were sourced from the Central Bank of Nigeria Statistical Bulletin and the Federal Statistical Bureau. The study covered twelve year period (2004-2015). Time series data were analyzed using the simple linear regression. The results reveals that PPT had positive and significant effect on Nigerian GDP. The study recommends that the government should provide the necessary human and material infrastructures that are needed to support petroleum business so they can earn more income that will boost taxation.
