The Federal Ministry of Finance has released detailed implementation guidelines designed to facilitate an orderly transition from Nigeria's repealed tax statutes to the country's newly reformed fiscal framework.
The general guidelines, signed by the Minister of Finance and Coordinating Minister of the Economy, Taiwo Oyedele, provide an operational roadmap for taxpayers, tax practitioners, and revenue authorities as they navigate the new legal landscape.
Central to the transition framework is the principle of non-retroactivity. The Ministry has stated unequivocally that all tax obligations, statutory returns, and liabilities connected to accounting periods that closed before January 1, 2026, will be administered solely within the legal architecture of the repealed legislation. Meanwhile, any transaction executed or corporate financial year ending after the commencement date will be governed entirely by the provisions of the Tax Acts 2025.
The new legislative package comprises three principal statutes: the Nigeria Tax Act, the Nigeria Tax Administration Act, and the Nigeria Revenue Service (Establishment) Act.
The Ministry indicated that the transition framework is intended to provide absolute legal clarity and prevent retrospective disputes. It directly addresses widespread corporate concerns regarding the treatment of outstanding tax liabilities, ongoing audits, unresolved tribunal matters, tax incentives, and routine compliance obligations as the country moves away from its previously fragmented statutory regime.
In a significant assurance to businesses and domestic investors, the government has committed to fully honouring all valid tax exemptions and incentives granted under the old laws until their stated expiration dates. This protection of legacy entitlements is designed to preserve investor confidence throughout the transition period.
For all new compliance requests, corporate tax filings, and enforcement actions, the Ministry has directed that these will be processed through the modern, automated systems of the Nigeria Revenue Service, specifically the REV 360 platform. The government expects this approach to eliminate the practical bottlenecks that frequently arise during major legal transitions, while ensuring consistent and uniform implementation across all tiers of government.
The issuance of these guidelines marks a critical step in operationalising Nigeria's most comprehensive tax reform in decades, providing the certainty that businesses and practitioners require to align their affairs with the new fiscal order.
