The Federal Government has issued transition guidelines for Nigeria’s new tax regime under the Tax Acts 2025.
The Ministry of Finance released the guidelines on Thursday to help taxpayers, revenue agencies, consultants and other stakeholders manage the shift from repealed laws to the new framework.
Finance Minister and Coordinating Minister of the Economy Taiwo Oyedele said the guidelines were built around clarity, fairness and administrative certainty.
According to the ministry’s position reported by Daily Post, tax liabilities and obligations connected to periods before January 1, 2026, will continue to be treated under the old tax laws.
That means assessments, audits, investigations, disputes and enforcement actions tied to pre-2026 periods will still be handled under the repealed legal framework.
Tax returns linked to accounting periods ending before January 2026 will also be filed under current laws. Returns due from January 1, 2026, onward will come under the new legal structure.
The Tax Acts 2025 include four major laws: the Nigeria Revenue Service Establishment Act, the Nigeria Tax Act, the Nigeria Tax Administration Act and the Joint Revenue Board Establishment Act.
The guidelines also state that existing tax exemptions and incentives granted under repealed laws will remain valid until their expiration dates, while new or pending requests will be assessed under the new tax laws.
The clarification is meant to reduce uncertainty for businesses and revenue authorities as the reform package moves toward implementation.
