The Nigeria Revenue Service (NRS) has directed all large taxpayers to fully implement the national e-invoicing and Electronic Fiscal System by July 31, 2026, warning that failure to comply could attract regulatory sanctions under existing tax laws.
The directive was announced in a statement issued by the Special Adviser on Media to the NRS Chairman, Dare Adekanmbi, following a public notice signed by the Executive Chairman of the Nigeria Revenue Service, Dr Zacch Adedeji.
According to the statement, the deadline marks a critical phase in the Federal Government’s drive to modernise tax administration through digital technology and improve tax compliance nationwide.
Large taxpayers required to complete implementation
The NRS explained that the directive builds on an earlier public notice issued on February 17, 2026, which introduced the implementation timetable for the national e-invoicing initiative and made participation mandatory for large taxpayers.
Under the directive, affected businesses are required to complete their onboarding process, integrate their systems with the national platform, conduct all necessary testing and begin transmitting invoices through the NRS e-invoicing system before the compliance deadline.
The agency stated:
“The Nigeria Revenue Service has set a July 31 deadline for all large taxpayers to wholly adopt the national e-invoicing and Electronic Fiscal System.”
Compliance monitoring already underway
The revenue authority disclosed that it has commenced compliance monitoring to assess the level of implementation among affected companies ahead of the deadline.
According to the NRS, organisations that fail to meet the prescribed requirements risk enforcement measures in line with applicable tax legislation.
The public notice stated:
“NRS has already commenced compliance monitoring activities in order to assess the level of adherence to the e-invoicing mandate among large taxpayers.”
It further warned:
“Consequently, any defaulting member may be subjected to appropriate regulatory and enforcement actions in accordance with the provisions of the relevant tax laws and regulations.”
The Service therefore urged affected companies to conclude all outstanding implementation activities without delay and commence invoice transmission before the deadline.
More than registration required
The NRS clarified that compliance goes beyond simply registering on the Merchant Buyer Solution, the platform supporting the national e-invoicing system.
According to the agency, businesses must also successfully integrate their internal systems through approved Access Point Providers (APPs) or Systems Integrators, complete validation and testing procedures, and begin transmitting invoices electronically in accordance with the approved implementation standards.
The Service added that compliant taxpayers will be expected to receive only electronic invoices containing valid Invoice Reference Numbers (IRNs) from their suppliers, reinforcing transparency and traceability across commercial transactions.
Over 1,000 companies already compliant
The directive applies to large taxpayers, defined by the NRS as companies with an annual gross turnover of ₦5 billion or more.
The agency disclosed that more than 1,000 companies had successfully complied with the e-invoicing requirements as of the first quarter of 2026.
Advancing digital tax administration
The national e-invoicing initiative forms part of the Nigeria Revenue Service’s broader strategy to digitise tax administration, improve transparency in business transactions and strengthen revenue collection.
By enabling the tax authority to receive transaction data in real time, the Electronic Fiscal System is expected to enhance audit efficiency, improve compliance monitoring and reduce tax leakages.
The NRS reaffirmed its commitment to supporting taxpayers throughout the implementation process, noting that it will continue to provide the technical assistance required to ensure the successful nationwide rollout of the digital invoicing framework.
