FG Issues Tax Transition Framework To Protect Reform Certainty

By Olumide Johnson

The federal government, through the Federal Ministry of Finance, has released transition guidelines for the implementation of Nigeria’s new tax regime, which took effect on 1 January 2026. The framework clarifies how taxpayers, businesses and revenue authorities will manage tax liabilities, audits, disputes, incentives, exemptions and compliance obligations spanning both the repealed and newly enacted tax laws. The guidelines follow the enactment of the Nigeria Tax Act 2025, Nigeria Tax Administration Act 2025, Nigeria Revenue Service (Establishment) Act 2025 and Joint Revenue Board (Establishment) Act 2025, which collectively restructured Nigeria’s tax administration system.

DECISION HIGHLIGHT

The government is prioritising implementation certainty, seeking to reduce legal ambiguity and compliance disruptions that typically accompany major tax reforms.

DECISION MEMO

Large-scale tax reforms often succeed or fail during implementation rather than legislation. The significance of the transition guidelines lies in their attempt to establish clear operational boundaries between the old and new tax systems, thereby reducing regulatory uncertainty for businesses and investors.

A central feature of the framework is the preservation of legal continuity. Tax liabilities arising before 1 January 2026 remain subject to repealed laws, while transactions occurring thereafter fall under the new regime. This approach addresses concerns over retrospective application and provides a clearer basis for compliance, audits and dispute resolution.

Taiwo Oyedele, Minister of Finance and Coordinating Minister of the Economy, stated that the framework is designed to ensure “clarity, fairness and administrative certainty” while creating a common understanding between taxpayers and revenue authorities.

Equally significant is the treatment of fiscal incentives. Existing tax exemptions and incentives granted under previous laws will remain valid until expiry, reducing the risk of policy disruption for businesses that made investment decisions under the former framework. However, new applications and pending requests will be assessed under the new legislation, signalling a gradual migration rather than an abrupt policy break.

The broader objective extends beyond administration. By consolidating multiple tax statutes, strengthening coordination among tax authorities and transforming the former Federal Inland Revenue Service into the Nigeria Revenue Service, the reforms seek to improve compliance efficiency, reduce multiple taxation concerns and enhance Nigeria’s investment competitiveness.

The transition guidelines therefore represent the operational bridge between tax reform legislation and practical implementation, a stage that will ultimately determine whether the reforms achieve their revenue mobilisation and investment objectives.
