E-invoicing is arriving in stages, not all at once. Where your business sits in that rollout depends entirely on turnover.
Who must comply, and when, comes down to three bands. This piece covers all three, largest first.
What the Merchant-Buyer Solution actually is
The Merchant-Buyer Solution (MBS) is the NRS platform behind Nigeria's e-invoicing rollout. It replaces manually issued invoices with ones generated and verified through the tax authority's own system.
A compliant e-invoice carries an Invoice Reference Number. Businesses connect to the system through an approved Access Point Provider or System Integrator, rather than issuing invoices purely on paper or in-house software.
Think of it as invoices reporting themselves to the NRS in real time, instead of waiting to be summarised on a monthly return.
The large-taxpayer deadline that has already passed
Large taxpayers, meaning businesses with ₦5 billion in annual turnover or more, had to complete onboarding and be transmitting invoices by 31 Jul 2026. That date has now passed, so a business in this bracket should already be live on the system.
The medium-taxpayer start date
Medium taxpayers begin from 1 Jul 2026. Our piece on the small and emerging-business end of the scale covers the later date for businesses below that band.
Why the rollout is staged at all
Onboarding every taxpayer at once would overwhelm both the NRS and the Access Point Providers that connect businesses to the system. Starting with the largest taxpayers lets the NRS fix problems on a smaller, better-resourced group first.
That is a practical reason, not a sign that smaller businesses matter less. Every band eventually joins the same system, on a timetable set well in advance.
What happens once your category is enforced
Once enforcement begins for a taxpayer category, non-compliance carries a penalty of ₦200,000 plus 100% of the tax due and interest at the CBN Monetary Policy Rate. That is on top of any VAT itself already due, so late adoption is not a cheap way to buy time.
The penalty is set in law, not left to discretion. It applies whether the failure to comply was deliberate or simply a missed deadline.
How to check which category you fall into
The bands are set by annual turnover. Large taxpayers sit at ₦5 billion and above. Medium and emerging bands sit below that.
Work out your own turnover for the last full year first. Then compare it against the three thresholds, rather than guessing which band feels right.
