Frequently Asked Questions
Quick answers to common e-invoicing questions.
What is NRS e-invoicing?
NRS (Nigeria Revenue Service) e-invoicing is the mandatory electronic invoicing system that requires businesses to generate, validate, and transmit invoices digitally through approved channels. It replaces traditional paper invoicing with a standardized digital format.
Who needs to comply with NRS e-invoicing?
Currently, large taxpayers and companies in specific sectors must comply. The scope is expanding progressively, with plans to include all VAT-registered businesses by 2026.
What is an IRN (Invoice Reference Number)?
An IRN is a unique 40-character identifier generated for each e-invoice. It contains a timestamp, business identifier, sequential number, and check digits. The IRN serves as proof that an invoice has been validated by NRS.
What is Peppol and why does it matter?
Peppol (Pan-European Public Procurement Online) is an international framework for exchanging electronic documents across borders. Nigerian businesses trading internationally benefit from Peppol compliance for seamless invoicing with global partners.
What is the difference between an APP and a System Integrator?
An Access Point Provider (APP) is certified to transmit invoices via the Peppol/NRS network. A System Integrator provides the software platform businesses use to create invoices. ZUTAX is a System Integrator that partners with PASPA (an APP) to provide complete e-invoicing capability.
What are the penalties for non-compliance?
Non-compliance can result in financial penalties, interest on unpaid taxes, increased audit scrutiny, and potential business disruption. The specific penalties vary based on the nature and duration of non-compliance.
How long does it take to get compliant?
