REFORM TALKS with Enam Obiosio
For years, it has been listening to the same argument whenever the issue of tax reform came up in Nigeria. The country was said to have a tax problem. Businesses complained about multiple taxation. Citizens complained about poor public services. Governments complained about inadequate revenue. Economists complained about low tax-to-GDP ratios. Yet despite all the complaints, very little changed because successive administrations often lacked either the political courage or the institutional capacity to confront the problem directly. Today, the numbers suggest that something significant may be changing.
Nigeria’s tax revenue rose by 49 percent to N15.8 trillion in the first five months of 2026, compared with N10.6 trillion during the same period in 2025. On the surface, that looks like a simple revenue statistic. I believe it is a lot more than that. It is perhaps the clearest evidence yet that the ongoing fiscal reforms of the Bola Ahmed Tinubu administration are beginning to produce measurable outcomes.
For decades, Nigeria operated one of the most unsustainable fiscal models in the world. The country relied excessively on crude oil receipts to fund government operations while maintaining one of the weakest tax mobilisation systems among major economies. Whenever oil prices rose, governments spent aggressively. Whenever prices fell, fiscal crises emerged. Budget planning became hostage to commodity cycles rather than anchored on stable domestic revenue generation. That model was never sustainable.
No serious country can build its future on volatile oil earnings alone. Oil prices are determined in international markets over which Nigeria has little control. Production levels are vulnerable to theft, vandalism, geopolitical disruptions and global energy transitions. Any government that wants long-term fiscal stability must ultimately build a stronger domestic revenue base. This is why I consider the N15.8 trillion revenue figure important.
The increase did not happen by accident. It reflects deliberate policy choices. The restructuring of tax administration, the establishment of the Nigeria Revenue Service, the expansion of the tax net, improved compliance mechanisms and the introduction of new revenue measures across sectors such as petroleum and mining are beginning to alter the fiscal landscape.
For too long, Nigeria’s tax conversation focused almost entirely on tax rates. The real issue, however, was never rates. The real issue was collection. A country can have high tax rates and still generate poor revenue if compliance remains weak. Conversely, a country can maintain moderate rates and generate substantial revenue if administration is efficient and leakages are minimised.
What appears to be happening today is a gradual shift from taxation by legislation to taxation by administration. Government is increasingly focusing on ensuring that taxes already due are actually collected. That distinction matters. Many Nigerians instinctively react negatively whenever tax reforms are discussed. The assumption is often that reforms automatically mean higher taxes. In reality, successful tax reform is less about increasing rates and more about improving compliance, broadening the tax base and reducing revenue leakages. The figures suggest progress on all three fronts.
More importantly, the revenue increase arrives at a critical moment in Nigeria’s economic history. The country faces enormous infrastructure deficits, growing social spending obligations, security challenges and rising demands for public investment. Financing these needs entirely through borrowing would be economically dangerous. Nigeria has already spent years trapped in a cycle where debt service obligations consume substantial portions of public revenue. Increasing tax collections offers a more sustainable alternative.
I have always argued that the true test of fiscal reform is not whether government can borrow more money. The real test is whether government can generate more money internally. The latest revenue figures suggest movement in that direction.
Yet I also believe caution is necessary. Higher revenue collection alone does not automatically translate into economic success. Governments do not earn public trust simply because they collect more taxes. They earn trust when taxpayers can see tangible evidence that their contributions are being used effectively. This is where the next phase of reform becomes crucial.
Citizens will increasingly ask legitimate questions. If tax revenue is rising by nearly 50 percent, where will the money go? Will infrastructure improve? Will healthcare services become more accessible? Will education outcomes strengthen? Will roads, railways, electricity and water systems improve? Will security conditions become more stable? These questions cannot be dismissed. Tax reform succeeds politically when citizens perceive a connection between taxation and public value. Without that connection, compliance eventually weakens and public resistance grows.
This is why revenue mobilisation and expenditure efficiency must advance together. Government cannot celebrate higher collections while ignoring questions about spending effectiveness. Every additional naira collected must be matched by greater transparency, accountability and service delivery.
Nevertheless, I believe the significance of the N15.8 trillion figure extends beyond public finance. It also carries important implications for investors. For years, investors worried about Nigeria’s fiscal vulnerability. Heavy dependence on oil revenues created uncertainty. Budget projections frequently collapsed whenever oil market conditions deteriorated. Revenue shortfalls increased borrowing requirements and weakened macroeconomic stability. A stronger domestic tax base reduces these vulnerabilities.
When governments can generate predictable revenue from domestic economic activity, fiscal planning becomes more reliable. Investors generally prefer environments where public finances are stable and less dependent on external commodity cycles. The reforms therefore strengthen Nigeria’s broader investment narrative. They also reinforce an important message about the Tinubu administration’s economic strategy.
Much of the public debate surrounding recent reforms has focused on the immediate costs. Fuel subsidy removal generated controversy. Exchange rate reforms generated controversy. Tax reforms generated controversy. That was always expected. Structural reforms are rarely popular during implementation. The more important question is whether they eventually produce measurable outcomes. The tax revenue numbers provide one of the first large-scale indicators that some reforms may be delivering results.
Of course, challenges remain substantial. Nigeria still has a relatively low tax-to-GDP ratio compared with many emerging economies. Large sections of the informal economy remain outside the tax system. Compliance costs remain high for many businesses. Tax administration still requires significant modernisation. Coordination among different levels of government remains imperfect. The journey is far from complete.
However, reforms should be judged not only by destination but also by direction. The direction appears increasingly clear. Nigeria is gradually moving away from a fiscal model built primarily on oil rents towards one anchored more firmly on domestic economic activity. That transition is essential if the country hopes to achieve sustainable development over the long term.
I also find it noteworthy that revenue growth is occurring at a time when economic activity remains under pressure in several sectors. This suggests that administrative improvements are contributing meaningfully to collections. In other words, government is not merely benefiting from economic expansion. It is becoming more effective at capturing revenue from existing economic activity. That is precisely what modern tax administration is supposed to accomplish.
Ultimately, I see the N15.8 trillion figure as more than a fiscal milestone. It is a governance signal. It suggests that Nigeria may finally be developing the institutional capacity required to finance its development ambitions from within. Countries become economically resilient when they generate sufficient domestic resources to fund national priorities. They become vulnerable when they rely excessively on commodity exports, borrowing or external assistance.
The lesson from the latest numbers is straightforward. Fiscal sustainability is not built in oil fields. It is built through institutions that can consistently mobilise domestic revenue. For years, Nigeria talked about widening the tax base, improving compliance and strengthening revenue administration. Today, the numbers suggest that those ambitions are beginning to move from policy documents into measurable reality.
The challenge now is ensuring that higher revenue translates into visible national progress. If that happens, the N15.8 trillion recorded in the first five months of 2026 may eventually be remembered not simply as a revenue achievement, but as evidence that Nigeria’s long-delayed tax revolution finally began to work.
