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, warning that defaulters risk regulatory and enforcement actions.
The directive follows a public notice issued on February 17, 2026, outlining the implementation timeline for the mandatory e-invoicing system, also known as the Merchant Buyer Solution (MBS).
In a statement on Sunday, NRS Chairman Zacch Adedeji urged companies with annual gross turnover of ₦5 billion and above to complete their onboarding, system integration, testing and begin transmitting invoices through the agency’s e-invoicing platform before the deadline.
The statement, signed by the chairman’s Special Adviser on Media, Dare Adekanmbi, said the NRS had commenced compliance monitoring to assess adherence among large taxpayers.
It warned that organisations yet to comply could face sanctions in line with relevant tax laws and regulations.
The agency advised affected businesses to urgently complete all outstanding onboarding and integration processes and begin invoice transmission ahead of the compliance deadline.
According to the NRS, more than 1,000 companies had complied with the e-invoicing requirements as of the first quarter of 2026.
The Service said compliance includes onboarding to the Merchant Buyer Solution, integration through approved Access Point Providers or Systems Integrators, successful validation and testing, active invoice transmission, and ensuring that suppliers issue only compliant e-invoices with valid Invoice Reference Numbers.
