The Nigeria Revenue Service (NRS) has set July 31, 2026, as the final deadline for all large taxpayers to fully implement the national e-invoicing and Electronic Fiscal System (also known as the Merchant Buyer Solution).
In a statement issued on Sunday, July 19, 2026, the agency warned that companies failing to meet the deadline risk facing regulatory and enforcement actions under existing tax laws.
Who is Affected?
Large taxpayers are defined as companies with an annual gross turnover of **N5 billion** and above. They are required to complete onboarding on the Merchant Buyer Solution (MBS), integrate their systems through approved Access Point Providers or Systems Integrators, and begin transmitting compliant e-invoices with valid Invoice Reference Numbers (RINs).
The NRS has already started compliance monitoring and urged defaulting businesses to urgently finalise all outstanding integration and testing activities before the cutoff date.
As of the first quarter of 2026, more than 1,000 companies had already complied with the requirements.
Background and Purpose
The e-invoicing initiative forms part of the NRS’s broader strategy to strengthen tax administration, enhance transparency, and promote voluntary compliance across the country. The system was rolled out in phases, with large taxpayers originally expected to begin full operations from August 2025. The timeline was later extended to allow for smoother transition and address operational challenges.
The agency reiterated its commitment to providing necessary support to taxpayers during the implementation process, while emphasising that full adoption is critical to the success of the electronic fiscal framework.
The July 31 deadline marks the end of the transition period for large taxpayers, after which the NRS will intensify enforcement efforts to ensure nationwide compliance.
