Nigeria’s ambitious tax reform agenda faces its first major implementation test as large companies race to comply with a nationwide e-invoicing mandate before the June 30 deadline, with penalties set to take effect from July 1 for non-compliant taxpayers.
“By June 30, if you are not compliant, you will be liable for fines starting July 1,” said Olumide Akinsola, country director of DigiTax Nigeria, an accredited e-invoicing service provider, during a virtual media briefing on Tuesday.
The National Revenue Service (NRS) requires companies with annual turnover of N5 billion and above to transmit invoices electronically through its Merchant Buyer Solution (MBS) platform by June 30, after which non-compliant businesses could face fines, interest charges and restrictions on claiming VAT input credits.

The rollout is one of the most significant steps in Nigeria’s push to modernise tax administration through technology, improve compliance and reduce leakages that have long undermined government revenue collection.
While tax authorities say adoption is improving, industry participants warn that a substantial number of eligible companies remain outside the system as the deadline approaches.
“Over a thousand of the roughly five thousand businesses in this cohort had complied as of late last year or early this year,” said Akinsola. “The NRS indicates they are seeing strong adoption, but a significant chunk remains outside.”
The figures suggest that thousands of large taxpayers may still need to complete compliance requirements before the June 30 deadline.
The financial implications extend beyond regulatory sanctions.
Under the framework, businesses can claim VAT input credits only on invoices transmitted and validated through the NRS platform.

Tax experts say this effectively makes e-invoicing a commercial necessity, as non-compliant suppliers could create additional tax costs for their customers.
“It is impossible to claim VAT input credits if those invoices were not transmitted to the NRS system,” said Akinsola in the media briefing. “Not being compliant means you are actually leaking revenue because the input VAT you cannot claim back has to be paid from your own pocket.”
Under the penalty regime, any VAT amount applicable to an invoice that is not transmitted after the compliance deadline may be treated as a fine, and interest is charged at 2 percent above the Central Bank of Nigeria’s Monetary Policy Rate.
The deadline for large taxpayers marks only the first phase of a broader nationwide rollout.
Medium-sized businesses with annual turnover between N1 billion and N5 billion will begin entering the regime from July 2026, with enforcement scheduled to begin between January and March 2027. Smaller businesses with turnover below N1 billion are expected to come under the framework in a later phase, with enforcement commencing in 2028.
The staggered implementation means the number of businesses affected by the policy will expand significantly over the next two years, increasing pressure on companies to upgrade systems and align internal processes with the new requirements.
The NRS e-invoicing framework requires businesses to generate, validate and transmit invoices electronically through accredited service providers. Each invoice is assigned a unique Invoice Reference Number and QR code, creating a real-time digital audit trail for tax authorities.
Officials and industry participants view the initiative as a key component of Nigeria’s broader effort to strengthen tax administration through data-driven compliance monitoring.
According to Akinsola, the framework now covers not only VAT reporting but also withholding tax, signalling the government’s intention to deepen the use of digital infrastructure across multiple tax categories.
Nigeria joins a growing number of African countries, including Kenya, Zambia, Ghana, Rwanda, and South Africa, that are deploying electronic invoicing systems to improve tax transparency and reduce revenue leakages.
Akinsola cited estimates showing that Africa loses the equivalent of about N20 trillion annually to tax gaps and leakages, with governments increasingly turning to technology-based compliance systems to improve collection efficiency.
For businesses, however, the coming weeks may determine more than compliance status.
The success or failure of the June 30 deadline will offer one of the clearest indications yet of whether Nigeria’s wider tax reform programme can move beyond legislation and policy announcements into effective enforcement and measurable compliance gains.
