The Nigeria Revenue Service (NRS) has established July 31, 2026, as the final date for large taxpayers to fully transition to the national Electronic Fiscal System and e-invoicing platform, often called the Merchant Buyer Solution (MBS). This requirement was detailed in an official notice released on February 17, 2026.
NRS Chairman Zacch Adedeji has called on impacted businesses to finish their system integration, testing, and onboarding phases before the cut-off. According to a Sunday statement released by Dare Adekanmbi, the Special Adviser on Media to the chairman, the agency is actively tracking compliance. Organizations that fail to meet these requirements may face legal penalties under existing tax regulations.
The mandate applies to companies generating at least N5 billion in annual gross turnover. As of the first quarter of 2026, over 1,000 businesses have already met these standards. To be compliant, companies must register on the MBS platform, integrate their systems through authorized providers, validate their processes, and ensure invoices are transmitted to the NRS in real time. Furthermore, businesses are instructed to only accept invoices from suppliers that include a valid Invoice Reference Number (RIN). This initiative aims to bolster tax administration, minimize revenue loss, and modernize the national tax infrastructure.
