E-Invoicing solution for large taxpayers deadline extended by 3 months as FIRS boosts support to help firms complete onboarding and integration
E-Invoicing solution for large taxpayers just received a major boost as the Federal Inland Revenue Service (FIRS) announced a three-month extension for firms to onboard and transition to the new system.
The announcement was made during a 2-Day E-Invoice Post Go-Live Workshop held in Lagos, where Chief of Staff to the FIRS Executive Chairman, Mr. Tayo Koleosho, revealed the extension through his representative, Mr. Emmanuel Eze, Director of Change Management.
According to Eze, the extension is not a delay tactic but a critical opportunity for companies to finalize integration, carry out transmission tests, and iron out any system readiness concerns well before enforcement begins.
“This extension is to ensure seamless onboarding, not to encourage procrastination,” Eze emphasized.
The E-Invoicing Solution for Large Taxpayers officially launched on August 1, 2025, as part of FIRS’ bold step toward modernizing Nigeria’s tax administration.
So far, more than 1,000 large taxpayers have successfully joined the platform, covering approximately 20% of the agency’s onboarding target.
Major players like MTN Nigeria, Huawei Nigeria, and IHS Nigeria are already transmitting live invoices.
Sixteen service providers have also been certified to act as both System Integrators and Access Point Providers—key enablers of widespread adoption.
Koleosho reiterated FIRS’s commitment to supporting taxpayers, promising continued availability of helpdesk services, sector-specific training sessions, and collaborative engagement with certified service providers.
From the technical side, Mr. Mohammed Bawa, Project Manager for E-Invoice, stated that all companies are expected to complete onboarding by November 1st, 2025, to begin full integration and live transmission.
“Integration timelines vary from two to twelve weeks based on complexity,” Bawa explained.
FIRS views the success of the E-Invoicing Solution for Large Taxpayers as dependent on mutual trust and collaboration among all parties involved—including taxpayers, consultants, and technology partners.
