Nigeria’s Federal Government issues transition guidelines for the Tax Acts 2025, outlining how taxpayers and tax authorities handle obligations during the changeover. The guidelines state that tax rules under the previous regime continue to apply until the end of 2025, while the new tax framework takes effect from January 1, 2026. Multiple reports describe the document as a framework to manage transitional issues, including how existing tax matters are treated as the legal regime changes.

The guidelines also address concerns about the timing of enforcement. The Minister of Finance and Coordinating Minister of the Economy, Taiwo Oyedele, is cited as saying the framework ensures the new laws are not applied retrospectively. This is presented as a key principle guiding the transition from the repealed tax laws to the Tax Acts 2025.

Overall, the outlets report that the government is providing procedural direction to support a smooth handover, specifying the start date for the new system and clarifying the approach to obligations before that date.
