The development is part of efforts to transform Nigeria’s fiscal and revenue framework, according to Bayo Onanuga, the president’s special adviser on information and strategy.

The national assembly had, in March,  the proposed laws after consultations with stakeholders.

On June 18, the legislature the bills to the president for assent.

The four proposed laws are the Nigeria tax bill, the Nigeria tax administration bill, the Nigeria revenue service (establishment) bill, and the joint revenue board (establishment) bill. 

Speaking on the president’s assent in a statement on Wednesday, Onanuga said Tinubu will sign the bills at the presidential villa in Abuja.

The special adviser said the event will be witnessed by the senate president, speaker of the house of representatives, senate majority leader, house majority leader, chairman of the senate committee on finance, and his house counterpart.

“When the new tax laws become operational, they are expected to significantly transform tax administration in the country, leading to increased revenue generation, improved business environment, and a boost in domestic and foreign investments,” the statement reads.

“The Chairman of the Governors Forum, the Chairman of the Progressives Governors Forum, the Minister of Finance and Coordination Minister of the Economy, and the Attorney General of the Federation will also attend the ceremony.

“One of the four bills is the Nigeria Tax Bill (Ease of Doing Business), which aims to consolidate Nigeria’s fragmented tax laws into a harmonised statute.”

Onanuga said by reducing the multiplicity of taxes and eliminating duplication, the bill would enhance the ease of doing business, cut taxpayer compliance burdens, and create a more predictable fiscal environment.

The presidential aide said the Nigeria tax administration bill will establish a uniform legal and operational framework for tax administration across federal, state, and local governments.

He said the Nigeria Revenue Service (establishment) bill repeals the current Federal Inland Revenue Service Act and creates a more autonomous and performance-driven national revenue agency — the Nigeria Revenue Service (NRS).

“It defines the NRS’s expanded mandate, including non-tax revenue collection, and lays out transparency, accountability, and efficiency mechanisms,” Onanuga added.

“The fourth bill is the Joint Revenue Board (Establishment) Bill. It provides for a formal governance structure to facilitate cooperation between revenue authorities at all levels of government.”

He said the joint revenue board bill introduces essential oversight mechanisms, including establishing a tax appeal tribunal and an office of the tax ombudsman.
