New Tax Reform Bills Set To Take Effect January 2026 – Adedeji

Executive Chairman of the National Revenue Service (formerly Federal Inland Revenue Service), Zacch Adedeji, has announced that the newly signed tax reform bills will take effect from January 1, 2026.

Speaking to State House correspondents on Thursday, Adedeji said the timeline was deliberately chosen to provide the government and stakeholders with six months to prepare, educate, and align the reforms with the fiscal calendar.

“Based on best practices globally, because when you have this kind of change, it takes time for all the stakeholders, participant operators, and even the regulator to change the system,” he said.

He further explained that the January start date was made possible through legislative support and executive foresight.

“So with the magnanimity of the National Assembly, Mr. President, the effective date will be January 1, 2026, by the special grace of Almighty God.”

Adedeji emphasized the importance of implementing major tax changes at the beginning of a fiscal year for better legal and operational alignment.

“When you have this kind of change, it’s not what you do mid-year. Because if the application of the law is better, you start from the beginning of the year,” he stated.

“So effective dates, by God’s grace, will be the first of January 2026,” he added.

According to Adedeji, the timeframe allows for adequate public sensitization, administrative planning, and full harmonization with the government’s budgeting and fiscal frameworks.
