This study adopted the technique of Fully Modified Ordinary Least Square (FMOLS) to analyze the time series data. The empirical result revealed that pioneer tax allowance is positively related to inclusive growth. Also, investment allowance has a direct and significant impact on inclusive growth in Nigeria during the period of study. Based on the findings, it was therefore recommended that tax authority should consider proportionately, increase of both pioneer and investment allowances, as this will attract more investors, and bring about inclusive growth in the economy.
