The Nigeria Revenue Service (NRS) has directed all large taxpayers to fully adopt the National E-Invoicing and Electronic Fiscal System (EFS) by July 31, 2026.
The directive follows a public notice issued by the agency on February 17, 2026, which outlined the implementation timetable and made the adoption of the National E-Invoicing and EFS, also known as the Merchant Buyer Solution (MBS), compulsory.
In the latest notice, signed by NRS Chairman Zacch Adedeji, large taxpayers were instructed to complete their onboarding, system integration, testing, and begin transmitting invoices through the NRS e-invoicing platform before the deadline.
According to a statement issued on Sunday by the Special Adviser on Media to the chairman, Dare Adekanmbi, the NRS has already commenced compliance monitoring activities in order to assess the level of adherence to the e-invoicing mandate among large taxpayers.
“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.
“Affected taxpayers are, therefore, advised to urgently conclude all outstanding onboarding and integration activities and commence invoice transmission before the compliance deadline.
“The NRS appreciates the cooperation of taxpayers and remains committed to providing the necessary support to ensure the successful implementation of the national e-invoicing regime,” the notice partly read.
It identified large taxpayers as companies with gross turnover of ₦5 billion and above.
The NRS noted that as of the first quarter of 2026, over 1,000 companies had complied.
Compliance with the e-invoicing and Electronic Fiscal System, the Service said, covers the completion of onboarding on the NRS Merchant Buyer Solution (MBS) and successful integration of taxpayer systems through approved Access Point Providers (APPs) and/or systems Integrators (SIs).
Others are completion of all required validation and testing activities, active transmission of invoices to the NRS e-invoicing platform in line with approved standards and guidelines, and ensuring the receipt of only compliant e-invoices with a valid Invoice Reference Number (RIN) from suppliers.
