We applied boundtesting of cointegration to check the long run relationship and Error Correction Model (ECM)to check the short relationship between tax revenue and its determinants. Results indicate that normalized cointegrating equation that budget deficit, total public debt, per capita income, informal industry, formal services, informal services have negative association with tax revenue while formal industry and trade openness have positive impact on tax revenue in long run. According to ECM results, there is a negative value of error correction coefficient, i.e., – 0.56. It indicates that whenever there is a deviation from jong run equilibrium path, variable adjusts toward the equilibrium.
