This study looked into the topic of e-taxation and enhanced tax compliance in Nigeria. The study aimed to achieve two particular goals. It investigated the impact of e-taxation on tax evasion in Nigeria, as well as the extent to which e-taxation has contributed to the reduction of tax avoidance in Nigeria. The study's analysis used secondary quantitative data from the Federal Inland Revenue Services (FIRS) and the National Bureau of Statistics (NBS). The study found that e-taxation had a considerable beneficial impact on tax evasion in Nigeria. The study found that the mean value of tax revenue increased after the implementation of e-taxation when compared to the mean value before the adoption of the e-taxation system. It also indicated that e-taxation has greatly helped in curbing the issue of tax evasion in Nigeria. The data analysis revealed a greater mean value for tax revenue following the implementation of e-taxation as compared to the mean value before the e-taxation system. The report provided numerous important recommendations, including the necessity for FIRS to develop an electronic tax payment system mobile App that will raise awareness and simplify the country's e-tax system. This study concluded that the e-taxation system in Nigeria achieves higher tax compliance than the manual approach.
