The NRS has extended the e-invoicing (MBS/EFS) compliance deadline for Large Taxpayers to 31 July 2026. Here's what affected companies must do to comply and avoid penalties.
Tax compliance in Nigeria is no longer just about what you file and when; it is now also about how you file it.
The Nigeria Revenue Service (NRS), formerly the Federal Inland Revenue Service (FIRS), has extended the compliance deadline for its National E-Invoicing & Electronic Fiscal System (EFS), also known as the Merchant Buyer Solution (MBS), to 31st July 2026, giving Large Taxpayers a final window to get compliant.
Here's what you need to know.
What is the MBS/EFS?
It is the NRS's digital platform for the real-time issuance, transmission, validation, and storage of invoices, a major shift in how businesses in Nigeria will handle tax reporting going forward.
What changed?
Under the original timeline (announced 23rd February 2026), Large Taxpayers were expected to comply between April and June 2026. That deadline has now been pushed to 31st July 2026, giving affected companies more time to complete onboarding, integration, and testing.
Who does this affect?
Large Taxpayers: these are businesses with a minimum annual gross turnover of ₦5 billion. If you're unsure whether your company falls within this bracket, it's worth confirming directly with the NRS.
Compliance Requirements for Large Taxpayers
To achieve compliance, Large Taxpayers are required to:
1. Complete Onboarding on the Merchant Buyer Solution (MBS): All affected companies must register and complete onboarding on the NRS MBS portal, including company verification and activation of access to the E-invoicing platform.
2. Integrate Systems Through Approved Channels: Taxpayers must integrate their internal accounting, ERP, and billing systems with the NRS platform through approved Access Point Providers (APPs) and Systems Integrators (SIs), enabling automated, real-time transmission of invoice data.
3. Complete Validation and Testing: Companies must complete all validation and testing activities required by the NRS to ensure system readiness and data accuracy before going live.
4. Transmit Invoices in Real Time: Following onboarding and testing, taxpayers must actively transmit all invoices to the NRS E-Invoicing platform at the point of issuance, in line with approved standards and technical guidelines.
5. Ensure Receipt of Compliant Invoices with a Valid IRN: Large Taxpayers must ensure invoices received from suppliers carry a valid Invoice Reference Number (IRN) issued by the NRS system. Only invoices with a valid IRN will be recognised for tax and compliance purposes.
Why it matters:
Non-compliance after 31st July 2026 attracts a penalty of ₦200,000 plus 100% of the tax due, plus interest at the prevailing CBN Monetary Policy Rate. Financial exposure is significant and avoidable with timely action.
Beyond compliance, What Does this mean for Businesses:
This mandate will reshape how businesses operate:
- Finance and IT teams will need to redesign workflows for real-time invoicing transmission
- Companies should budget for integration costs and technology upgrades
- Businesses must engage suppliers to ensure they can issue IRN-compliant invoices
- Electronic records transmitted to NRS will form part of the audit trail for future tax audits
- Relevant staff must be trained on the new invoicing process.
Our Recommendation
With the deadline fast approaching, Large Taxpayers should immediately take the following steps:
- Confirm classification and assess current invoicing systems
- Commence onboarding on the MBS portal
- Engage an NRS-approved APP or SI for system integration
- Conduct pilot testing of invoice transmission
- Sensitize internal teams and vendors on the IRN requirement
