NRS Compliance
Understanding
NRS e-Invoicing.
Nigeria's Federal Inland Revenue Service is moving all businesses to real-time digital invoicing. Here's what that means for you — and how DigiTax makes it simple.
The Mandate
What is the NRS e-Invoicing System?
The National Revenue Service (NRS) e-Invoicing System is Nigeria's national mandate for digital tax invoicing, introduced by FIRS (the Federal Inland Revenue Service) to align with Nigeria's Digital Economy Policy and Strategy (2020–2030).
It replaces traditional paper-based and fragmented electronic invoicing with a unified, real-time digital framework. Businesses must now generate, digitally sign, and transmit compliant invoices to the NRS network at the time of sale.
Non-compliance carries financial penalties and increases exposure during FIRS audits. The mandate is not optional — it is a legal requirement.
Issuing Authority
Federal Inland Revenue Service (FIRS) — Nigeria's primary tax authority.

The Process
The compliant invoice lifecycle.
Every compliant invoice must pass through four stages before it is considered valid under the NRS mandate.
Invoice Created
Invoice is generated with required fields including invoice type, party details, line items, and currency (NGN).
Validated
DigiTax validates the invoice data against NRS schema requirements, catching errors before submission.
Cryptographically Signed
A unique IRN is assigned and the invoice is digitally signed with a FIRS-approved cryptographic certificate.
Transmitted
The signed invoice is transmitted to the NRS network and confirmation is returned in real time.
