The Federal Government has officially released the General Guidelines for the implementation of the Tax Acts 2025, providing taxpayers and revenue authorities with a clear roadmap for the shift from repealed tax laws to the new framework which takes effect on January 1, 2026.
The document, issued by the Federal Ministry of Finance, addresses long-standing concerns over how existing tax obligations, ongoing disputes, and pending applications will be handled during the transition period.
It confirms that all tax liabilities, assessments, audits, investigations, and enforcement actions relating to periods before the commencement date will continue to be treated under the repealed laws.
In a significant clarification for businesses and individuals, the Guidelines state that tax returns for accounting periods ending before January 1, 2026, must be filed under the previous tax regime, while those ending from that date onward will fall under the new Tax Acts.
The Tax Acts 2025 comprise 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. Each takes effect from its respective enactment date, with the Nigeria Tax Act specifically commencing on January 1, 2026.
On the issue of tax incentives, the Guidelines provide that existing exemptions granted under the repealed laws will remain valid until their expiration dates. However, all new applications and pending requests will now be evaluated under the provisions of the new tax framework.
Speaking on the development, the Honourable Minister of Finance and Coordinating Minister of the Economy, Mr. Taiwo Oyedele, described the Guidelines as a crucial instrument for managing the transition without subjecting taxpayers to retrospective application of the new laws.
“This is a significant milestone in Nigeria’s tax reform journey,” Mr. Oyedele said. “The Guidelines are anchored on three core principles—clarity, fairness, and administrative certainty. We want taxpayers to know exactly where they stand as we move into this new era.”
The Guidelines also cover the treatment of income taxes, transaction taxes, development levies, record-keeping obligations, and transactions that straddle both the old and new regimes.
The Ministry noted that the framework is designed to promote uniform implementation across all levels of government, including the Nigeria Revenue Service, State Internal Revenue Services, the FCT Internal Revenue Service, and Local Government Revenue Committees.
The Federal Government reiterated its commitment to building a transparent and efficient tax system that strengthens revenue administration, encourages voluntary compliance, and enhances Nigeria’s investment climate.
