Short answer: NRS e-invoicing applies to VAT-registered businesses in stages, based on annual gross turnover. Businesses with ₦5 billion or more had to be fully live by 31 July 2026. Businesses with ₦1 billion to ₦5 billion went live on 1 July 2026, with enforcement expected from January to March 2027. Businesses below ₦1 billion are expected to start in 2027, with mandatory adoption targeted for January 2028. Check your phase with our free readiness checker.
E-invoicing deadlines by turnover
| Annual gross turnover | Go-live | Enforcement |
|---|---|---|
| ₦5 billion and above (large) | Required now | Full compliance due by 31 July 2026 |
| ₦1 billion to ₦5 billion (medium) | 1 July 2026 | Expected January to March 2027 |
| Below ₦1 billion (small and emerging) | Expected from 2027 | Mandatory adoption targeted for January 2028 |
Turnover means total sales in your filed returns, not profit. Dates for smaller businesses may change, so watch for NRS updates.
What is NRS e-invoicing?
It is Nigeria’s national electronic invoicing system, run by the Nigeria Revenue Service through the Merchant Buyer Solution (MBS). Instead of sending a PDF or paper invoice on its own, your business sends each invoice through the NRS system in real time. Each valid invoice receives a unique reference number.
How businesses connect
You do not connect to the NRS directly. You go through an NRS-accredited Access Point Provider (which validates and sends invoices) or a System Integrator (which links your accounting or ERP software). Businesses without accounting software can usually raise invoices on a provider’s web portal. You need a Tax Identification Number (TIN) to register.
What happens if you do not comply?
- Under the Nigeria Tax Administration Act 2025, a taxable supply not processed through the system can attract ₦200,000, plus 100% of the tax due, plus interest.
- Your customers may not be able to claim input VAT on invoices that did not go through the system, so large buyers may stop accepting them.
Why smaller suppliers may need to act sooner
If you sell to large companies, banks, telecoms firms or government agencies, they need valid e-invoices to claim their input VAT. Expect some of them to ask suppliers to send e-invoices before the small-business deadline.
What to do now
- Confirm your annual turnover and whether you are registered for VAT.
- Get a TIN if you do not have one (we can help).
- Move invoicing out of Word, Excel or paper into software, or plan to use a provider’s portal.
- Choose an NRS-accredited provider and test before your go-live date.
- Train the staff who raise invoices.
