New Tax Reform Laws to Take Effect January 1, 2026, Says Revenue Service Chairman

Zacch Adedeji, Executive Chairman of the National Revenue Service (formerly Federal Inland Revenue Service), announced that the newly signed tax reform bills will come into effect on January 1, 2026. The six-month delay is intended to allow for planning, public education, and alignment with the fiscal calendar.

Speaking to State House Correspondents on Thursday, Adedeji emphasized the need for adequate preparation, stating, “Based on global best practices, such significant changes require time for stakeholders, operators, and regulators to adapt their systems.” He expressed gratitude to the National Assembly and the President for setting the effective date, adding, “By the special grace of Almighty God, the reforms will take effect on January 1, 2026.”

Adedeji underscored the importance of launching the reforms at the start of a new calendar year, noting, “This kind of change is best implemented from the beginning of the year, not mid-year, to ensure smooth application of the law.”
