The Petroleum Industry Act (2021) and Nigeria’s Fiscal Regime: A Desk Review of Taxation, Governance, and Revenue Mobilization

Abstract

The Petroleum Industry Act (PIA) 2021 represents a landmark reform of Nigeria's petroleum sector, introducing a comprehensive legal, fiscal, and regulatory framework intended to improve governance, enhance transparency, strengthen revenue generation, and promote sustainable investment in the oil and gas industry. This study critically reviews the fiscal and regulatory provisions of the PIA, with particular emphasis on petroleum taxation and its implications for tax administration and revenue mobilization. The study adopts a qualitative desk research approach, relying exclusively on secondary data obtained from statutory documents, government publications, academic literature, institutional reports, and policy papers. Data were examined using content and documentary analysis to identify major reforms, implementation challenges, and emerging policy issues. The findings indicate that the PIA has significantly modernized Nigeria's petroleum fiscal regime through the introduction of a dual tax framework comprising Hydrocarbon Tax and Companies Income Tax, the establishment of specialized regulatory institutions, and improved governance mechanisms for host community development and petroleum operations. However, the implementation of the Act continues to face several challenges, including regulatory overlaps, administrative bottlenecks, oil theft, inadequate production monitoring, revenue leakages, unresolved contractual issues, and limited institutional capacity. These challenges constrain the realization of the Act's intended fiscal and economic objectives. The study concludes that although the PIA provides a robust framework for petroleum sector governance and taxation, its long-term success depends on effective implementation, institutional strengthening, enhanced inter-agency coordination, and sustained regulatory certainty. The study recommends strengthening compliance mechanisms, deploying monitoring technologies, improving regulatory collaboration, and ensuring policy consistency to maximize revenue generation and enhance investors' confidence in Nigeria's petroleum industry.
