The adoption of digital tax systems has become central to modern fiscal administration, particularly in emerging economies seeking to enhance transparency and revenue mobilization. This study examined the effects of e-filing system adoption on tax revenue from Company Income Tax (CIT), Value Added Tax (VAT), and Petroleum Profit Tax (PPT) in Nigeria over the period 2013–2024. Employing the Autoregressive Distributed Lag (ARDL) model with the Pooled Mean Group (PMG) estimator, the study analyzed the long-run relationships between tax revenues and e-filing adoption. The findings revealed that e-filing had a positive and statistically significant effect on VAT revenue, demonstrating that digital tax platforms improved efficiency in VAT collection and broadened the tax base. Similarly, PPT revenue recorded a positive and statistically significant impact, though at the 10% level, suggesting moderate but growing effectiveness of e-filing in petroleum tax administration. However, e-filing exerted an insignificant effect on CIT revenue, highlighting persistent structural challenges, taxpayer resistance, and compliance loopholes within the corporate tax framework. The study concluded that while e-filing has enhanced VAT and PPT revenues, its effectiveness in improving CIT collection remains limited. It was recommended that policymakers strengthen enforcement mechanisms for corporate tax compliance, address structural bottlenecks, and invest in continuous taxpayer education to enhance the efficiency and credibility of the e-filing system.
