Nigeria is implementing mandatory e-invoicing through the Nigeria Revenue Service (NRS) Merchant-Buyer Solution, or MBS. The rollout is phased by annual turnover, and the published schedule separates go-live from later enforcement.
This guide explains how to prepare, based on NRS legislation, implementation material and OpenPeppol information available on 25 September 2026. Published dates remain indicative and may be adjusted by the NRS.
Nigeria e-invoicing implementation timeline
| Taxpayer segment | Annual turnover | Go-live and enforcement |
|---|---|---|
| Large taxpayers | Above NGN 5 billion | Effective implementation in November 2025; enforcement scheduled for April to June 2026 |
| Medium taxpayers | NGN 1 billion to NGN 5 billion | Go-live on 1 July 2026; post-go-live review in October to November 2026; enforcement scheduled for January to March 2027 |
| Emerging taxpayers | Below NGN 1 billion | Go-live on 1 July 2027; post-go-live review in October to November 2027; enforcement scheduled for January to March 2028 |
The February 2026 NRS rollout notice describes these dates as indicative and subject to adjustment. It also says enforcement follows engagement, pilot and post-go-live review. For a practical summary of that public notice, see the KPMG Nigeria tax alert. Confirm your current deadline directly with the NRS before implementation.
Who and what are covered?
The Nigeria Tax Administration Act 2025 requires a person making a taxable supply to use the Electronic Fiscal System when the NRS deploys it and to maintain accurate transaction records through that system. The phased MBS schedule determines when different taxpayer segments move through onboarding, go-live and enforcement.
The current NRS schema includes B2B, B2C, B2G and G2B invoice types. B2B invoices are validated through the MBS in near real time. B2C invoices or receipts must be reported within 24 hours and include a QR code. The NRS indicated in October 2025 that further cross-border schema and timing information would follow, so international scenarios require confirmation.
The statutory penalty for failing to process a taxable supply through the fiscalisation system is NGN 200,000, plus 100% of the tax due and interest at the prevailing Central Bank of Nigeria monetary policy rate per year. The NRS can also impose separate penalties for failure to provide required technical access. Enforcement should be assessed against the phase that applies to the taxpayer.
How the MBS fiscalisation model works
- The supplier creates invoice data in its ERP, the NRS portal or another connected system.
- The data is submitted to the MBS using the portal or an approved integration route.
- The NRS validates the invoice and returns an Invoice Reference Number (IRN), validation information and the data needed for the QR code.
- The supplier provides the validated e-invoice or its human-readable representation to the buyer.
- The parties retain the invoice, status information and audit evidence. Cancellations or rejections should be handled within the 72-hour period described in the NRS implementation material.
The NRS resources describe several connection models: direct ERP integration, an NRS-authorised System Integrator, an Access Point Provider using Peppol, or the NRS portal for manual and batch processing. Peppol is an available exchange route, not the only permitted connection method.
Formats, identifiers and record retention
The MBS developer documentation is based on the Universal Business Language model and supports XML and JSON through the API. Use the current NRS schema and validation rules, including later changes to invoice types, tax categories, partial payments and units of measure.
- NRS Tax ID: confirm the 13-digit identifier for each entity in the NRS Tax ID service.
- Peppol participant ID: the current Nigeria scheme is 0244 (NG:TID), followed by the 13-digit Tax ID.
- Fiscalisation reference: store the NRS-issued IRN and related validation status with the invoice.
- Buyer document: ensure the human-readable invoice carries the correct QR code and matches the validated structured data.
- Corrections: preserve links between invoices, cancellations, credit notes and other adjustments.
The Nigeria Tax Administration Act 2025 sets a general minimum record-retention period of six years after the relevant year of assessment. Records must be sufficient, kept in English and maintained in the prescribed form. Retain them longer where another tax, corporate or sector-specific rule applies.
Your Nigeria e-invoicing readiness in four steps
1. Confirm your taxpayer segment and scope
- Calculate annual turnover using the basis accepted by the NRS and confirm your segment.
- Confirm whether your business is in engagement, pilot, post-go-live review or enforcement.
- Map B2B, B2C, B2G, G2B and cross-border flows by legal entity.
- Identify branches, group companies, exemptions and special tax treatments that need written clarification.
2. Enable the business and choose a connection model
- Complete the required MBS onboarding and verify entity, Tax ID and contact data.
- Choose between the NRS portal, direct API integration, an authorised System Integrator or an authorised Access Point Provider.
- Check the provider’s current NRS authorisation and approved service scope. General Peppol certification does not by itself prove local MBS authorisation.
- Define who owns certificates, credentials, error handling and operational support.
3. Map, validate and test your invoice data
- Map ERP fields to the current NRS UBL-based schema in XML or JSON.
- Validate Tax IDs, invoice type, tax categories, product classification, units, payment data and references.
- Test IRN generation, QR codes, duplicate prevention, cancellations, rejections, credit notes and partial payments.
- Run end-to-end tests with representative B2B and B2C cases before production.
4. Go live, reconcile and retain evidence
- Monitor validation results and reconcile them with ERP and tax records.
- Resolve rejected invoices within the permitted operational window.
- Keep the structured invoice, IRN, QR data, status history and supporting records for at least six years.
- Track NRS changes to the schema, cross-border treatment, provider authorisations and enforcement dates.
Erste Schritte mit Qvalia
Qvalia’s Hosted Access Point provides the underlying Peppol infrastructure for organisations and service providers that want to operate an Access Point under their own identity. The operating organisation applies for and maintains its Peppol Service Provider role, PKI certificate, governance obligations and any NRS-specific authorisation. Approval remains with OpenPeppol, the relevant Peppol Authority and the NRS.
For Nigeria, confirm whether the operating organisation must be authorised as an Access Point Provider, a System Integrator or both. Qvalia can provide and operate the agreed Access Point infrastructure and support structured-data mapping, validation, Peppol transport, monitoring and ERP integration within the agreed delivery scope.
