Large Companies Face Sanctions Over July 31 E-Invoicing Cut-Off, NRS Warns

NRS Gives Large Taxpayers July 31 Deadline for Mandatory E-Invoicing

The Nigeria Revenue Service (NRS) has directed all large taxpayers to complete the adoption of its national electronic invoicing and Electronic Fiscal System (EFS) by July 31, 2026, warning that non-compliance could attract regulatory sanctions.

In a public notice signed by NRS Chairman, Zacch Adedeji, the agency reminded affected companies to complete registration, system integration, testing and the transmission of invoices through the national e-invoicing platform before the deadline.

The directive follows the implementation schedule earlier announced by the tax authority in February 2026 for the nationwide rollout of the electronic invoicing system, also known as the Merchant Buyer Solution (MBS).

According to the NRS, compliance monitoring is already underway to assess how well large taxpayers are meeting the new requirements. Companies that fail to comply may face enforcement measures in line with existing tax laws and regulations.

The agency advised businesses yet to complete the process to urgently finalise all outstanding onboarding and integration activities through approved Access Point Providers or System Integrators.

The NRS defines large taxpayers as companies with an annual gross turnover of ₦5 billion or more. It disclosed that more than 1,000 companies had successfully complied with the new system as of the first quarter of 2026.

To meet the requirements, businesses must complete onboarding on the Merchant Buyer Solution platform, successfully integrate their systems, pass all validation and testing processes, begin transmitting electronic invoices, and ensure invoices received from suppliers carry a valid Invoice Reference Number (IRN).

The tax authority said it remains committed to supporting taxpayers throughout the implementation process while encouraging full compliance ahead of the July 31 deadline.
