President Bola Tinubu has assented to the four tax reform bills recently passed by the National Assembly.
The leadership of the National Assembly and some legislators, governors, ministers, and aides of the President attended the short ceremony, which took place at the Presidential Villa yesterday.
The four bills: the National Assembly passed the Nigeria Tax Bill, the Nigeria Tax Administration Bill, the Nigeria Revenue Service (Establishment) Bill, and the Joint Revenue Board (Establishment) Bill after extensive consultations with various interest groups and stakeholders.
According to the presidency, the new tax laws will significantly transform tax administration in the country, leading to increased revenue generation, improved business environment, and a boost in domestic and foreign investments.
In his address to reporters, the Chairman of the Federal Inland Revenue Service (FIRS), Zacch Adedeji, said the new tax regime would begin on January 1, 2026.
He said, “It takes time for all the stakeholders, participants, operators, and the regulator to change the system.
“So, with the magnanimity of the National Assembly, Mr President assented to the bills. Therefore, the effective date will be January 1, 2026. We have six full months for both sensitisation and planning. This is also considering the fiscal year of the government because when you have this kind of change; it’s not what you do in the media.”
The new tax bills introduced by the Tinubu administration had been enveloped in widespread controversy and sparked scathing criticisms and stiff opposition from many including some governors who believed that some states would not be able to pay staff salaries if some sections of the bills make it into law.
However, the Presidency and the National Assembly said stakeholders had been engaged across the country and the fears of the governors had been allayed.
