Zacch Adedeji: Building Smarter, Simpler, More Predictable System

By introducing digital systems, e-invoicing, unified taxpayer identification, standardised procedures and wider participation, the Nigeria Revenue Service under Zacch Adedeji, is building a tax system that is easier to comply with, difficult  to evade and better suited to a modern economy, writes Dike Onwuamaeze

Nigeria’s tax system has undergone one of its most significant transformations in decades. Under the leadership of the Executive Chairman of the Nigeria Revenue Service (NRS), Dr. Zacch Adedeji, the reform agenda seeks to move tax administration away from a predominantly manual, fragmented and compliance-heavy system towards one that is increasingly digital, integrated, data-driven, transparent and easier to navigate.

However, the reform is not merely about collecting more taxes. It is about changing the way government administers revenue. The Nigeria Tax Administration Act, 2025, which commenced on January 1, 2026, sets out uniform procedures intended to facilitate tax compliance and optimise revenue.

The broader reform programme was also designed to widen participation in the tax system, reduce leakages, improve information-sharing, standardise procedures and strengthen Nigeria’s non-oil revenue base.

For ordinary Nigerians, however, tax reform can sound complicated and intimidating. For many individuals, the word “tax” immediately raises questions about deductions from salaries, new levies, penalties and possible demands from tax officials. For businesses, the concerns may be about compliance costs, documentation, digital systems and uncertainty over how new rules will affect operations.

For investors, the central question is if Nigeria provide a tax environment that is predictable, transparent and sufficiently stable to support long-term investment?

What the Nigeria Tax Administration Act Means

One of the most important components of the new architecture is the Nigeria Tax Administration Act, 2025. In practical terms, the Act provides the administrative framework for how taxes are assessed, collected and accounted for. It also defines the responsibilities of tax authorities and seeks to establish more uniform procedures.

For the average taxpayer, the significance of this is that tax administration should increasingly be based on clearer and more standardised procedures rather than inconsistent practices. The law applies to persons required to comply with tax laws, whether acting personally or on behalf of another person. It also defines areas of responsibility for the NRS and other tax authorities.

This standardisation is particularly important in a country where businesses have sometimes complained about overlapping demands, uncertainty over applicable obligations and the administrative burden of dealing with multiple systems. A more coherent system can reduce those frictions.

It can also improve the government’s ability to identºify who should pay what, where payments should go and whether the money collected has actually been remitted.

Digitalisation: Moving Tax Administration Online

Perhaps the most visible aspect of the reforms is the growing use of technology. The NRS now operates digital taxpayer services through which taxpayers can manage several aspects of their tax affairs. The official taxpayer self-service portal provides facilities including profile management, e-invoicing, self-tax filing, payments, tax-clearance certificates, tax-wallet information, refunds and assessments. The significance of this cannot be overstated.

The Service has launched Rev360, a digital tax administration platform designed to create a more integrated, taxpayer-focused experience. The platform supports the NRS’ stated transition to what it describes as Tax Administration 3.0, with objectives including better service delivery, compliance management, transparency and simpler interactions with taxpayers.

This matters because the traditional tax office is not necessarily the most efficient place for a modern taxpayer to conduct routine business. A small entrepreneur should not have to spend hours travelling to a government office simply to obtain information, file a return or resolve a straightforward administrative issue. A professional who operates from Lagos but has clients across Nigeria should be able to interact with the tax system electronically. A large corporation should be able to integrate its financial and invoicing systems with the tax authority without relying on a maze of paper processes.

The NRS taxpayer self-service platform allows taxpayers to manage profiles, file taxes, make payments, obtain tax-clearance documents, view assessments, track refunds and manage e-invoicing.

The NRS has also emphasised the importance of technology integration across revenue authorities. Adedeji recently described technology integration as critical to the success of the new tax laws and urged sub-national tax authorities to embrace it to improve efficiency.

E-Invoicing: What Does It Actually Mean?

An electronic invoice (e-Invoice) is a digital record of a commercial transaction between a seller and a buyer. Instead of relying entirely on paper invoices or fragmented accounting records, transactions can be recorded and transmitted through an approved electronic system.

The NRS has been rolling out its electronic invoicing system in phases. The earlier national e-invoicing regime was introduced for large taxpayers, with the system designed to provide greater transparency, efficiency and real-time visibility into business transactions.

The subsequent phased rollout has extended attention to medium and emerging taxpayer categories. The NRS has said the implementation is being sequenced through engagement, pilot testing, go-live implementation, post-deployment review and eventual compliance enforcement.  For businesses, e-invoicing should not be viewed solely as another government requirement.

Properly implemented, it can help businesses maintain better records of sales and purchases, reduce disputes, improve accounting and establish reliable documentation of transactions. For government, it creates greater visibility into economic activity. For the wider economy, it can help formalise transactions and reduce the opportunities for sales to be deliberately hidden from the tax system. That is particularly important in an economy where a significant amount of commercial activity takes place outside highly formal corporate structures.

Widening the Taxpayer Base

Another major pillar of the reform is expanding participation in the tax system. Nigeria has a large population and a huge informal economy. One consequence is that the formal tax base can carry a disproportionate share of the burden. This raises an important fairness question.

If one company properly declares its income and pays the applicable tax while another company with comparable economic activity deliberately conceals its transactions, the compliant business is effectively disadvantaged. Expanding the taxpayer base is therefore not necessarily synonymous with making every Nigerian pay more tax. It means identifying taxable economic activity more effectively and ensuring that people and businesses that are legally required to contribute are brought into the system. The objective should be to distribute responsibility more fairly.

Technology is central to this process because a modern government can use legitimate information from different public systems to identify economic activity more accurately than a system that depends entirely on taxpayers physically presenting themselves at tax offices. The NRS’s digital taxpayer services and identification systems are part of this emerging architecture. But wider participation must go hand in hand with public confidence. Taxpayer information is sensitive. The public must therefore be assured that data is handled responsibly, that access is governed by clear rules and that technology is being used to improve administration rather than create arbitrary demands.

From Fragmented Records to Better Intelligence

One of the most important but least understood aspects of modern tax administration is information-sharing. A government cannot administer a complex economy effectively if different institutions maintain disconnected records that cannot be reconciled.  

For example, a company’s registration information, tax identity, declared transactions and other legitimate government records may exist in different places.

When such information can be appropriately connected, the tax authority can build a ºmore accurate picture of economic activity. That has two sides. For compliant taxpayers, better information can reduce duplication and make it easier for government to verify declarations.

For those deliberately hiding income or transactions, it reduces the opportunities for concealment. This is where data-driven tax administration becomes fundamentally different from old-style tax collection. The tax authority is no longer relying solely on what a taxpayer chooses to present. It can increasingly use information to assess whether declarations are consistent with available evidence.

That does not mean every discrepancy should automatically be treated as fraud. Businesses make mistakes, systems fail and legitimate differences can occur. It means the system can become more evidence-based and risk-focused, allowing the tax authority to concentrate enforcement resources where there are genuine reasons for concern.

What the Reforms Mean for Individuals, Businesses

For individuals, one of the most important messages is that tax reform should not automatically be interpreted as a new tax demand. There is an important difference between tax policy and tax administration. Tax policy determines such matters as what is taxable, who is liable and applicable rates. Tax administration concerns the systems and procedures through which those laws are implemented.

The Nigeria Tax Administration Act is primarily an administrative framework. Its stated objective is to facilitate compliance and optimise revenue through consistent and efficient administration.  For employees, professionals, traders and self-employed people, the growing emphasis on digital administration means that accurate records will become increasingly important.

This can actually benefit individuals. A person who knows exactly how much he earns, what he spends and what income is taxable has a better understanding of his own financial position.

For businesses, the reform presents both responsibilities and opportunities. The responsibility is where a business has a tax obligation, it must comply with the applicable law, maintain appropriate records and submit accurate information. But businesses can also benefit from a system that is more predictable and standardised.

Investors do not look only at tax rates when deciding where to put money. They also look at the quality of administration. They want to know whether rules are clear, whether they are consistently applied and whether competitors are subject to the same standards. A predictable tax system can therefore be an economic advantage.

Building a Tax System for the Future

The transformation being pursued by the NRS under Adedeji is therefore best understood as an attempt to modernise one of the most important interfaces between the Nigerian state and its citizens. No reform of this scale can be completed overnight. The NRS is building towards a system in which technology replaces unnecessary paperwork, information replaces guesswork, standardisation replaces fragmentation and wider participation replaces excessive dependence on a relatively narrow group of taxpayers.

The Nigeria Tax Administration Act provides the legal foundation for more uniform and efficient administration. Digital platforms are changing how taxpayers interact with the Service. E-invoicing is bringing greater visibility to transactions. Information-sharing is improving the ability to identify economic activity. And wider taxpayer participation is aimed at creating a more equitable revenue base.

For individuals, this should mean clearer obligations and easier access to services. For businesses, it should mean better records, more predictable procedures and a more level competitive environment. For investors, it means greater clarity about Nigeria’s fiscal architecture.

For government, it means stronger non-oil revenues, fewer leakages and better information for economic planning. And for the wider economy, the ultimate objective is a revenue system capable of supporting development without unnecessarily obstructing enterprise.

In all, a smarter tax system is one that collects fairly, administers efficiently, closes leakages, encourages compliance and creates the fiscal certainty needed for a stronger economy. That is what Nigerians need to understand about the NRS reforms.
