The study examined the impact of tax revenue both oil and non-oil on the economic development in Nigeria. Data used for the study was secondary data which is for a period between 2011-2017 and was sourced from the database of Federal Inland Revenue Service (FIRS) and the United Nation Human Development Report 2018. The foundation for the theoretical framework of the study is Human Development Theory. Multiple regression was used for the analysis and the findings revealed that non-oil tax had a significant impact on economic development in Nigeria while oil tax had no significant impact on the economic development in Nigeria. To be self-sufficient and avoid financial difficulties due to changes in policy from fossil fuel to zero-emission by developed economies, it was recommended that government at all levels diversify the economy in order to improve their internally generated revenue.
