Our Tax Newsletter for the third quarter of 2025 reviews a busy period. Nigeria’s tax landscape kept moving, and both the courts and the revenue authority shaped that movement.
Two themes ran through the quarter. Judicial decisions clarified how far administrative oversight reaches. Meanwhile, the Federal Inland Revenue Service pushed ahead with its technology agenda.
What the courts said
The courts affirmed the broad investigative powers of regulatory agencies. In doing so, they marked out the scope of administrative oversight within the tax space more clearly than before.
That matters for day-to-day practice. Taxpayers facing an information request need to know when an agency is acting within its powers and when it has overreached. The quarter’s decisions give more to work with on that question.
What the revenue authority did
The FIRS advanced its innovation agenda on three fronts.
- Electronic invoicing. Implementation of the e-invoicing system continued, moving invoice reporting closer to real time.
- Research-driven initiatives. The authority launched work aimed at grounding policy and administration in better data.
- Compliance tools. New tools arrived to support and monitor taxpayer compliance.
Together these point in one direction. Tax administration in Nigeria is becoming more digital, more continuous and less forgiving of manual processes.
Why this quarter matters
Nigeria is passing through the most transformative phase in its tax administration. The wider reform programme continues to unfold, and judicial pronouncements and regulatory enforcement anchor it as it does.
Businesses should therefore treat this as a period for vigilance rather than routine. Systems built for periodic filing may not cope with near real-time reporting. Records that once satisfied an occasional query may not satisfy a continuous one.
What to do now
Three practical steps help. First, review whether your invoicing systems can meet electronic reporting requirements without manual intervention. Second, check that your records would withstand an agency information request. Third, keep watch on how the courts continue to define the limits of investigative power.
The reform package that takes effect in January 2026 raises the stakes further. Our note on how the tax reforms affect M&A transactions covers the transactional side, and the Nigeria Revenue Service publishes current guidance and circulars.
