NRS sets July 31 deadline for Nigeria's largest companies to adopt e-invoicing
Nigeria's tax authority has set a firm July 31 deadline for large companies to adopt a digital invoicing system, exposing non-compliant businesses to enforcement actions and forcing immediate supply chain adjustments.
The Nigeria Revenue Service (NRS) has issued a final July 31 deadline for large taxpayers to fully adopt the national e-invoicing and Electronic Fiscal System. Companies that fail to integrate the technology face regulatory and enforcement actions under existing tax laws.
The mandate targets businesses with an annual gross turnover of N5 billion and above. Dare Adekanmbi, Special Adviser on Media to the NRS Chairman, stated that more than 1,000 companies had complied as of the first quarter of 2026. The agency has now launched active compliance monitoring to assess adherence across the remaining taxpayer base.
For corporate executives, meeting the mandate demands substantial back-office adjustments. Affected businesses must onboard onto the Merchant Buyer Solution platform and connect their internal systems via approved Access Point Providers or Systems Integrators. Invoices must undergo strict validation testing and carry valid Reference Invoice Numbers (RINs) before transmission to the NRS.
The compliance burden extends deeply into corporate supply chains. The NRS warned that businesses must ensure they only receive compliant e-invoices carrying valid RINs from their own suppliers. This effectively forces large companies to audit their vendor networks and reject non-compliant documentation to avoid falling foul of the new regime.
"The NRS has already commenced compliance monitoring activities in order to assess the level of adherence to the e-invoicing mandate among large taxpayers," Adekanmbi said. "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 electronic invoicing framework is a core pillar of the NRS's strategy to strengthen tax administration, improve transparency, and enhance voluntary compliance nationwide. The system originally went live for large taxpayers in August 2025, following pilot deployments that started in January 2025.
NRS Chairman Zacch Adedeji had previously outlined the phased rollout in a February 2026 public notice. The July 2026 deadline marks the definitive end of a transition period that already saw one enforcement extension to November 2025. With the agency now shifting from technical support to active enforcement, companies have a narrow window to finalize system integrations.
