Nigeria’s tax reform story in 2025 and 2026 has been genuinely remarkable. The Nigeria Tax Act 2025 and the Nigeria Tax Administration Act 2025, the most comprehensive reworking of our tax laws in decades, are signed and in force. The National Revenue Service is live. The e-invoicing mandate is operational.
For the first time in our fiscal history, government has constructed foundational digital infrastructure at real scale and with evident commitment. But there is a structural gap at the heart of this architecture that, if left unaddressed, will significantly limit the return on all this investment. That gap is interconnection. Closing it requires the deliberate construction of a 5th Pillar.
The 4 Pillars Already Built
Nigeria’s modern tax architecture now rests on four operational pillars. The first is Digital Identity: the integration of NIN and BVN into tax administration, making the Tax Identification Number a meaningful, verifiable anchor. The second is the Payment Rail: NIBSS and the commercial banking system as the substrate for auditable, verified tax remittances. The third is Rev360: the NRS’s platform for tax filing, assessment, and selfservice compliance. The fourth is e-Invoicing: the NRS mandate for real-time invoice submission and validation by businesses above the turnover threshold. Each pillar represents a genuine policy achievement. They were not built easily, and their existence is the foundation on which the next phase of reform will stand. But for all their individual strength, they share a fundamental limitation: they do not talk to each other systematically as required. More importantly, they do not talk to the private sector platforms where Nigerian businesses actually operate. They are, in the most consequential sense, islands.
The Gap: Infrastructure Without Interconnection Is Incomplete
Consider a small business owner in Lagos. She uses Taxtech’s TPay®Payroll to pay her staff, TPay®Expenses to to manage her books, and TFleet® to run her supply chain. Not one of these systems has a validated connection to Rev360. Not one of them generates e-invoices natively. So at month-end, a member of her team exports data manually, reformats it, and submits it through the government portal – hoping the figures reconcile, hoping the submission registers, hoping no error triggers an audit. Errors accumulate. Deadlines are missed. The lived experience teaches that tax compliance is cumbersome and, where possible, avoidable.
This is not a failure of will, and it is not a failure of the government platforms. It is a failure of architecture. We built the highway but did not build the on-ramps. Every naira of friction that results from this gap taxes business operations rather than business income. Every manually re-entered invoice is a data integrity risk. Every disconnected platform is a revenue leakage opportunity.
Nigeria’s tax-to-GDP ratio of 13.5% will not reach the 18%+ target through government infrastructure alone. The four pillars are necessary but insufficient. The private sector must be connected. And connection requires a framework.
The 5th Pillar: An API-Led National Tax Ecosystem
What Nigeria needs, and what the existing regulatory architecture is almost ready to enable, is an API-led national tax ecosystem. The concept is architecturally clear: private sector platforms: payroll software, accounting packages, ERP systems, fintechs, government revenue administration platforms, should be able to connect, on accredited and validated
terms, to NRS infrastructure. The connection must be governed, secure, and standardised. The taxpayer should not need to interact with a government portal. Tax compliance should be an automatic output of ordinary business operations, a by-product of doing business, not a separate administrative burden layered on top of it.
This is the 5th Pillar: not a new government platform, but the policy, standards, and accreditation framework that enables the private sector to complete the architecture government has started. An API (application programming interface) is simply a structured, secure handshake between two software systems. The technology exists. The question is whether the regulatory framework will be built to govern it.
Nigeria Has Done This Before: The ARIP Lesson
I want to draw a precedent from within our own regulatory landscape, because it is directly instructive. In 2020, Nigeria’s Securities and Exchange Commission launched the Accelerated Regulatory Incubation Programme (ARIP) as Nigeria’s first formal regulatory sandbox for capital market technology. ARIP created a structured, supervised pathway for innovative securities platforms to test products with real customers under SEC oversight, with regulatory forbearance during the incubation period and a clear route to full SEC registration on successful completion.
ARIP was not a technology innovation. The SEC did not build the platforms. What the SEC built was the framework that made it legal, safe, and commercially viable for the private sector to build them. The result has been a new generation of Nigerian securities technology companies operating within properly regulated markets. The framework produced the innovation, not the other way around.
The Joint Tax Board, the coordinating authority for the NRS and Nigeria’s States Internal Revenue Services (SIRS), is precisely positioned to do the same for tax technology. A Tax Technology Accreditation Framework: a supervised, governed pathway for private sector platforms to connect to NRS and SIRS infrastructure, under validated API standards, with the same regulatory discipline that ARIP brought to capital markets. The NRS already operates a version of this model for e-invoicing Access Point Providers (APP) and Systems Integrators (SI). The decision needed is to expand it.
Four Things the NRS and JTB Should Do Now
These are not aspirational proposals. They are actionable steps that, taken together, would create the 5th Pillar within a twelve-month horizon.
- Publish open API standards for connectivity to Rev360 and all NRS infrastructure – versioned, documented, and publicly available to all accredited platforms.
- Expand the existing e-invoicing APP and SI accreditation framework into a broader Tax API Access Point Programme, covering the full tax compliance value chain.
- Establish a mandatory data governance requirement for accredited platforms: ISO 27001 certification and active NDPC Data Protection Compliance Organisation (DPCO) registration. The personal and financial data of Nigerian taxpayers must be protected at every point in the system.
- Constitute a multi-stakeholder technical working group (JTB, NRS, FIRS, NDPC, and
accredited private sector platforms) to design the framework collaboratively and
deliver a draft within six months.
The Private Sector Is Already There
I write not as an observer but as a practitioner. Taxaide Technologies Limited (Taxtech®) has been building Nigeria’s tax technology infrastructure since 2015. We are an NRS-licensed APP and SI for e-invoicing. Through TServe®, our government revenue administration platform, we power the full revenue lifecycle (assessments, collections, receipting, and enforcement) for Onigbongbo LCDA in Lagos (with OnigbongboRev® / PayOnigbongbo®), and once did for Oredo Local Government in Edo State (with OredoRev®/OredoPay®), and Yaba LCDA in Lagos (with YabaRev® and YabaPay®). We have been a licensed DPCO) by the Nigeria Data Protection Commission since 2019 and hold ISO 27001:2013 certification. We are not describing what is possible. We are describing what is already working, at scale, in production, in multiple Nigerian jurisdictions. The private sector is not waiting to be convinced. It is waiting to be connected.
The Decision That Remains
The Nigeria Tax Act 2025 is signed. The National Revenue Service is live. The e-invoicing mandate is operational. A decade of legislative advocacy and administrative reform has produced a foundation that previous generations of Nigerian tax administrators could only have dreamed of. The returns on that investment will be determined by what happens next.
Infrastructure without interconnection is incomplete. The 5th Pillar is not an optional enhancement. It is the mechanism by which every naira invested in the first four pillars delivers its full return to Nigeria. I call on the Joint Tax Board, working with the National revenue Service and the Honourable Minister of Finance, to take ownership of this agenda.The laws are signed. The platforms are live. The private sector is ready. What is left is the decision to connect.
