Nigeria’s tax reforms could redefine the economy — by Adewale Okoya

For decades, Nigeria’s greatest fiscal paradox has been an economy large enough to rank among Africa’s biggest, yet a tax system too fragmented and inefficient to generate the revenue needed to support its ambitions. With one of the world’s lowest tax-to-GDP ratios, successive governments relied heavily on crude oil revenues while borrowing to finance infrastructure, education, healthcare and security. That model proved increasingly unsustainable whenever oil prices fell or production declined.

The sweeping tax reforms introduced by President Bola Tinubu’s administration may represent the country’s most significant fiscal restructuring in decades. Signed into law in June 2025, the reforms consolidated multiple tax statutes into a simplified framework, created the Nigeria Revenue Service to replace the Federal Inland Revenue Service, strengthened coordination among federal, state and local tax authorities through the Joint Revenue Board, and introduced a unified system for tax administration aimed at reducing duplication, broadening the tax base and improving compliance.

The reforms were not designed simply to collect more taxes. Their broader objective is to create a fairer, simpler and more predictable tax system that encourages investment while ensuring government has a more reliable source of revenue beyond oil. Low-income earners and many small businesses benefit from higher exemption thresholds, while compliance is expected to improve through digital tax administration, electronic invoicing and better taxpayer identification.

Although full implementation is still underway, early indicators suggest the reforms are beginning to reshape Nigeria’s fiscal landscape. Businesses now operate under a clearer legal framework, reducing the confusion created by overlapping federal and state taxes. Revenue authorities are increasingly sharing information, while digital systems are making tax collection more transparent and efficient. The reforms have also strengthened investor confidence by signalling the government’s commitment to building a modern fiscal system capable of supporting long-term economic growth.

The significance of these gains extends well beyond government revenue. A stronger tax system reduces dependence on volatile oil receipts, allowing public finances to become more predictable. Stable revenue enables governments to plan multi-year investments in transport infrastructure, electricity, healthcare, education and digital connectivity—sectors that directly influence productivity and private sector competitiveness.

Perhaps more importantly, a broader tax base could gradually reduce Nigeria’s dependence on borrowing. In recent years, debt servicing has consumed a substantial share of government revenue, leaving limited fiscal space for development spending. As tax administration becomes more effective and compliance improves, government revenues can grow without necessarily increasing tax rates. This strengthens fiscal sustainability while improving Nigeria’s credit profile and lowering borrowing costs over time.

The reforms could also help formalise Nigeria’s vast informal economy. Millions of micro and small businesses operate outside the tax net, limiting their access to formal finance, government programmes and investment opportunities. Simplified tax rules and digital compliance systems make it easier for these businesses to enter the formal economy, expanding financial inclusion while creating a larger and more transparent tax base.

Technology will be central to the reforms’ long-term success. Electronic filing, integrated taxpayer databases and digital invoicing reduce opportunities for tax evasion while lowering compliance costs for businesses. Combined with Nigeria’s thriving fintech ecosystem, these innovations could significantly improve revenue mobilisation and strengthen confidence in public institutions. The International Monetary Fund estimates that recent tax policy and administrative reforms could substantially increase government revenue as implementation gathers pace, particularly through improved compliance and digital administration.

The benefits extend beyond public finance. Greater fiscal stability makes Nigeria more attractive to domestic and foreign investors. Businesses value predictable tax rules as much as competitive tax rates. A transparent and harmonised tax system reduces regulatory uncertainty, improves the ease of doing business and encourages long-term investment decisions.

If consistently implemented, these reforms could transform Nigeria’s economic trajectory over the next decade. Higher and more stable public revenues would support sustained investment in infrastructure, reducing the cost of doing business and improving industrial competitiveness. Better-funded education and healthcare systems would strengthen human capital, while improved transport networks and electricity supply would enhance productivity across agriculture, manufacturing and services.

The reforms also align with Nigeria’s ambition to become a regional manufacturing and investment hub under the African Continental Free Trade Area (AfCFTA). As intra-African trade expands, countries with efficient tax systems, predictable regulations and stronger institutions will be better positioned to attract industries seeking access to the continent’s growing consumer market.

Nevertheless, legislation alone cannot guarantee success. Sustaining the momentum will require disciplined implementation, political consistency and continued public engagement. Taxpayers are more willing to comply when they see tangible improvements in public services and greater accountability in government spending. Transparency in revenue utilisation will therefore be just as important as efficiency in revenue collection.

Nigeria’s tax reforms should not be viewed simply as another fiscal policy initiative. They represent an opportunity to redefine the relationship between the state and its citizens by replacing dependence on oil with a more resilient, diversified and sustainable revenue model. If the reforms are implemented faithfully, insulated from political reversals and supported by continued improvements in governance, they could become one of the defining economic achievements of the decade.

For too long, Nigeria’s economic fortunes have risen and fallen with global oil prices. A modern tax system offers something far more valuable: the prospect of financing national development through the strength of its own economy. That is the foundation upon which durable prosperity is built.
