Abstract
The study empirically examined the effect of trade openness on non-oil tax revenue in Nigeria for the period 1986-2022. Data were collected from Central Bank of Nigeria (CBN) statistical bulletin 2022 and World Development Indicator database. Unit root test was conducted and the result indicated that the variables were not in the same order of integration. Autoregressive Distributed Lag Model (ARDL) bound test was conducted and it was found that there is a co-integration among the variables. Result from ARDL long run model showed that trade openness and real gross domestic product had significant positive effect on non-oil tax revenue while inflation rate, exchange rate and foreign direct investment had no significant effect on non-oil tax revenue in Nigeria. The study therefore recommended international trade should be encouraged as it generates income through taxation in Nigeria. However, concern should be to encourage more exportation in other to have favorable balance of payment in Nigeria.
