Nigeria Revenue Service Sets July 31 Deadline for Large Taxpayers to Adopt E‑Invoicing

The Nigeria Revenue Service (NRS) has issued a public notice requiring all large taxpayers—companies with an annual gross turnover of ₦5 billion or more—to fully adopt the national electronic invoicing and Electronic Fiscal System (EFS), also known as the Merchant Buyer Solution (MBS), by 31 July 2026.

The notice, signed by NRS Chairman Dr. Zacch Adedeji and released through Special Adviser on Media Dare Adekanmbi, says the agency has already begun monitoring compliance and warns that any taxpayer that fails to meet the deadline will face regulatory and enforcement actions under existing tax laws.

To comply, firms must complete onboarding to the MBS, integrate their accounting systems through approved Access Point Providers or Systems Integrators, finish validation and testing, and start transmitting invoices that include a valid Invoice Reference Number. The agency reported that more than 1,000 eligible companies had already complied as of the first quarter of 2026.
