Abuja, June 18, 2026 – The Federal Government has released comprehensive transition guidelines for the implementation of the Tax Acts 2025, providing clarity on how taxpayers, businesses, revenue agencies, and other stakeholders will migrate from Nigeria’s old tax laws to the new tax framework that took effect on January 1, 2026.
The guidelines, issued by the Federal Ministry of Finance, establish the rules and procedures for managing tax obligations, assessments, audits, disputes, incentives, and compliance requirements during the transition period. The move is widely regarded as a significant milestone in Nigeria’s ongoing efforts to modernize its tax administration system and strengthen revenue generation.
According to the document, the new tax framework comprises four key legislations: the Nigeria Revenue Service (Establishment) Act, the Nigeria Tax Act, the Nigeria Tax Administration Act, and the Joint Revenue Board (Establishment) Act.
The government clarified that all tax liabilities, assessments, investigations, audits, enforcement actions, and disputes relating to periods before January 1, 2026, will continue to be governed by the repealed tax laws. However, all tax matters arising from accounting periods commencing on or after January 1, 2026, will be administered under the new legal framework.
The guidelines further specify that tax returns for accounting periods ending before January 1, 2026, must be filed under the former tax laws, while returns for periods ending after that date will fall under the provisions of the Tax Acts 2025.
Importantly, the government assured taxpayers that existing tax incentives, exemptions, and reliefs granted under the repealed laws will remain valid until their respective expiration dates. However, all new applications and pending requests will be considered in accordance with the provisions of the new tax legislation.
Speaking on the release of the guidelines, the Honourable Minister of Finance and Coordinating Minister of the Economy, Mr. Taiwo Oyedele, described the Tax Acts 2025 as a landmark achievement in Nigeria’s tax reform agenda.
He explained that the transition framework was designed to ensure that the new laws are not applied retrospectively while providing certainty on how existing obligations and future transactions will be treated.
“The guidelines are anchored on three fundamental principles—clarity, fairness, and administrative certainty,” the minister stated, emphasizing the government’s commitment to creating a predictable and business-friendly tax environment.
The guidelines are expected to promote uniform implementation across the Nigeria Revenue Service (NRS), State Internal Revenue Services, the Federal Capital Territory Internal Revenue Service, Local Government Revenue Committees, tax practitioners, and taxpayers nationwide.
Economic analysts have welcomed the development, noting that a clear and transparent tax system is critical for improving investor confidence, encouraging voluntary tax compliance, reducing disputes, and enhancing Nigeria’s competitiveness as an investment destination.
The Federal Government reaffirmed its determination to build a modern, efficient, and transparent tax administration system capable of supporting economic growth, improving public revenue management, and fostering sustainable national development.
