The federal government has released implementation guidelines for the Tax Acts 2025, providing a transition roadmap from Nigeria’s old tax framework to the new one that took effect on January 1, 2026.
The guidelines, issued by the federal ministry of finance, are directed at taxpayers, tax practitioners, revenue authorities and other stakeholders navigating obligations under the new regime.

What Are the Tax Acts 2025?
The Tax Acts 2025 is a package of four laws: the Nigeria Revenue Service (Establishment) Act, the Nigeria Tax Act, the Nigeria Tax Administration Act, and the Joint Revenue Board (Establishment) Act. Together, they replace the previous tax laws that governed revenue collection in Nigeria.
The new framework became operative from January 1, 2026, though each act takes effect from its specific commencement date as stated in the law.
What Changes and What Stays?
The guidelines draw a clear line between old obligations and new ones.
Any tax liabilities, audits, investigations or disputes tied to periods before January 1, 2026, will still be handled under the old tax laws. Tax returns for accounting periods that ended before that date must also be filed under the previous rules.
From January 1, 2026, however, all returns and obligations fall under the new framework.
Existing tax incentives and exemptions granted under the repealed laws will remain valid until they expire. New applications, and those already pending, will be assessed under the Tax Acts 2025.
Three Principles Driving the Guidelines
Minister of Finance and Coordinating Minister of the Economy, Taiwo Oyedele, said the guidelines rest on three core principles: clarity, fairness and administrative certainty.
Oyedele, who engineered the new tax laws as the Chairman, Presidential Fiscal Policy and Tax Reforms Committee, described the Tax Acts 2025 as a significant milestone in Nigeria’s tax reform drive and said the guidelines are designed to prevent the new laws from being applied retrospectively, meaning no taxpayer will be penalised for obligations incurred before the new rules came into force.
The guidelines also cover income taxes, transaction taxes, development levies, record-keeping requirements and transactions that straddle both the old and new regimes.
Who Must Comply?
The guidelines are intended to standardise implementation across all revenue bodies: the Nigeria Revenue Service, state internal revenue services, the FCT Internal Revenue Service, local government revenue committees and tax practitioners.
The government said the aim is uniform application nationwide, reducing confusion and inconsistency in how the new tax laws are enforced across different levels of government.
Why It Took This Long
The release of the guidelines had been delayed. In January, Oyedele attributed the hold-up to uncertainty over the final gazetted version of the tax laws. The document has now been sent to the federal government press for official gazetting.

Beyond the immediate transition, the federal government says the broader goal is a transparent, efficient and modern tax system that boosts revenue, encourages voluntary compliance and improves Nigeria’s investment climate.
