The Federal Government has unveiled official guidelines for the implementation of the Tax Acts 2025, providing clarity on how taxpayers, businesses, and revenue agencies should navigate Nigeria’s new tax system.
The guidelines, issued by the Ministry of Finance, outline the transition from the old tax regime to the new framework, which officially took effect on January 1, 2026.
According to the government, tax matters relating to periods before the commencement date will continue to be handled under the repealed laws, while obligations arising from January 1, 2026, onward will be governed by the new tax framework.
The document also explains how tax returns, audits, investigations, disputes, incentives, exemptions, and transactions that cut across both tax regimes will be treated.
“Tax returns relating to accounting periods ending before January 1, 2026, will be filed under the previous tax laws,” the ministry stated.
The government further clarified that tax incentives and exemptions previously granted under old laws will remain valid until they expire.
However, fresh applications and pending requests will now be assessed based on the provisions of the Tax Acts 2025.
Speaking on the development, Finance Minister Taiwo Oyedele described the new guidelines as a crucial step in ensuring a smooth transition to Nigeria’s reformed tax system.
“The guidelines are anchored on three key principles – clarity, fairness and administrative certainty,” Oyedele said.
He added that the document is designed to prevent confusion, ensure consistency in implementation, and avoid the retrospective application of the new laws.
The ministry noted that the guidelines will help taxpayers, tax practitioners, state revenue agencies, and other stakeholders better understand their obligations under the new tax regime.
The government also reiterated its commitment to building a transparent and efficient tax system capable of boosting revenue generation, encouraging voluntary compliance, and improving Nigeria’s business environment.
