Nigeria’s Federal Government has released transition guidelines to help stakeholders move to the Tax Acts 2025. The guidelines, issued on Thursday by the Ministry of Finance, are intended to guide taxpayers, revenue agencies, tax consultants and other parties during the changeover period. Multiple outlets report that the framework addresses how existing tax obligations are handled when the new laws begin and how overlapping issues across regimes are managed, including ongoing audits, investigations, pending disputes, enforcement actions, tax incentives, and record-keeping requirements.

The Finance Minister and Coordinating Minister of the Economy, Taiwo Oyedele, says liabilities and obligations tied to periods before January 1, 2026 remain under the previous tax laws, including assessments, audits and related enforcement for those earlier periods. Tax returns for accounting periods ending before January 2026 are also to be filed under current laws. Returns due from January 1, 2026 onward will follow the new legal framework.

The Tax Acts 2025 are described as four major laws introduced as part of the tax reform agenda: the Nigeria Revenue Service (Establishment) Act, the Nigeria Tax Act, the Nigeria Tax Administration Act, and the Joint Revenue Board (Establishment) Act. Existing exemptions and incentives under repealed laws remain valid until their expiration dates, while new or pending incentive requests will be assessed under the Tax Acts 2025.
