Nigeria is tightening compliance on value-added tax (VAT) and withholding tax (WHT) by shifting from retrospective audits to real-time reporting of business transactions.
The approach gives tax authorities direct visibility into transactions as they occur, reducing reporting gaps and limiting the scope for discretionary assessments.
“The logical evolution for all tax administration is fiscalisation,” said Timothy Siloma, partner, tax reporting and strategy at PwC Nigeria, during a PwC webinar titled Tax Technology and E-invoicing in Nigeria.
According to Siloma, the objective is to pivot from reviewing transactions after they occur to accessing information directly from the point of generation in real time.
He highlighted VAT and WHT as areas where real-time visibility could address longstanding reporting gaps, particularly within Nigeria’s large informal economy.

Fiscalisation, which is the reporting of transactions in real or near-real time, represents a structural shift from reviewing transactions after the fact to monitoring economic activity as it happens.
In Nigeria, this shift is already reshaping compliance practices. Rather than relying on retrospective audits and discretionary assessments, tax authorities are increasingly seeking real-time access to transaction data generated by businesses, fundamentally altering how resident companies manage tax exposure.
Beyond expanding visibility, fiscalisation directly links the quality of transaction data to tax outcomes, reducing the scope for post-hoc explanations or reconciliations.
“Going forward, garbage in will result in immediate and automated tax consequences,” Siloma warned, highlighting the stakes for companies that fail to maintain accurate records.
Kenya’s experience offers a clear vision of this system in full effect. Siloma described it as “full fiscalisation,” where the revenue authority’s visibility directly dictates tax deductibility.
In practice, this means businesses cannot claim expenses for transactions that are not visible to the tax authority. While Nigeria’s rollout is more phased, beginning with large taxpayers, the direction is unambiguous: compliance is being embedded directly into business processes.

Early implementation has already exposed structural weaknesses on the taxpayer side. Mohammad Bawa, e-invoicing project manager for the Nigeria Revenue Service (NRS), highlighted data integrity as a major obstacle.
“We had challenges with the legacy data of taxpayers during onboarding processes because many taxpayers have inactive email addresses, which creates issues during enablement,” he explained.
Sector-specific business models have also required system flexibility. Bawa clarified that the e-invoicing platform is a “data gathering system” meant to enhance, not replace, existing filing systems.
To ease adoption, the NRS has leaned on engagement rather than enforcement alone. Participation from professional bodies, technical support channels, and developer communities has all been encouraged, alongside simulation portals for testing, highlighting a collaborative approach to implementing a potentially disruptive system.
For resident companies, the reforms carry strategic implications as well as operational challenges. Kenneth Erikume, tax reporting and strategy lead at PwC Nigeria, warned that richer government data increases exposure for unprepared firms.
“There could be potential for additional penalties and interest and additional assessment, because the government would have more information,” he said, noting that greater transparency does not automatically translate into a reduced enforcement environment.

At the same time, fiscalisation forces the tax function to the forefront of corporate technology strategy. “This is where the opportunity for invoicing comes, because for the first time, in a tech conversation, tax is taking the lead in those conversations,” Erikume said.
Companies that invest early in aligning systems to the new regime can automate complex withholding tax calculations, streamline VAT credit management, and improve audit readiness, turning compliance into a competitive advantage.
Kenya’s example demonstrates both the promise and the pressure of full fiscalisation; it reduces ambiguity by linking tax outcomes directly to transaction data but also removes flexibility for businesses whose systems are not fully aligned.
Nigeria’s phased approach suggests a similar future, where non-compliance is harder to hide, and every transaction has fiscal significance.
Fiscalisation marks a turning point in Nigeria’s tax system, embedding compliance into every transaction. For companies and investors, the reforms offer both risks and opportunities. Those who act quickly to align their systems will gain clarity and predictability, while those who fall behind will be exposed in a data-driven environment.
