Tax Ombud warns against revenue-first approach to tax reforms
Nigeria's Tax Ombud warns that pursuing revenue targets without taxpayer trust could undermine tax reform sustainability.
Tax Ombud Warns Against Revenue-First Approach to Tax Reforms
Nigeria's first Tax Ombudsman, Dr. John Nwabueze, has cautioned that the country's ambitious tax reform agenda risks structural failure if the federal government prioritizes collection targets over taxpayer trust — warning that pursuing revenue growth through enforcement alone, without building institutional fairness, could undermine the sustainability of the entire tax system.
What Was Said
The warning was delivered in a speech read on Nwabueze's behalf by his Chief of Staff, Dr. Peter Iwegbu, at the 36th anniversary conference of the Finance Correspondents Association of Nigeria (FICAN) in Lagos over the weekend. The conference, themed "Building on the Gains of Recapitalisation, Tax Reforms, and Fintech Revolution," brought together industry players across Nigeria's financial sector.
Nwabueze's central argument was that revenue growth and taxpayer confidence must reinforce each other rather than operate as competing priorities. "Nigeria cannot build a sustainable revenue system by focusing only on what citizens and businesses must pay," he said. "We must also focus on why they should trust the system through which they pay." He described the relationship between taxpayers and tax authorities as a contract of responsibility running in both directions: citizens and businesses have a legitimate obligation to pay lawful taxes, but the state equally owes them an administration that is fair, transparent, accountable and consistent with the law.
The Data Behind the Warning
Nwabueze grounded his caution in a specific comparison: Nigeria's tax-to-GDP ratio stood at just 8.2% in 2023, less than half the roughly 16.1% average recorded across 38 comparable African economies. He framed this gap not as evidence that Nigeria simply needs more aggressive enforcement, but as a signal of how far the country's tax and compliance culture has lagged — and argued that closing it requires taxpayers who understand, trust and are willing to engage with the system voluntarily, rather than compliance driven purely by compulsion.
He also addressed the role his own office plays in this equation, clarifying that the Tax Ombud was established "neither to encourage tax resistance nor to undermine lawful tax administration," but to give taxpayers a credible, independent channel through which legitimate grievances can be raised and resolved. The Office of the Tax Ombud was itself established under the Joint Revenue Board of Nigeria (Establishment) Act, 2025, and is empowered to resolve complaints relating to tax, regulatory fees, customs duty and excise matters.
Technology Isn't a Silver Bullet
Nwabueze also pushed back on the assumption that digital transformation alone can resolve Nigeria's tax trust deficit. Despite the changes brought by Nigeria's fintech revolution, he argued that technology cannot substitute for institutional fairness — digital reforms must actively make the tax system simpler, more accessible and more responsive, rather than creating additional friction for taxpayers. He pointed specifically to Nigeria's growing digital identity infrastructure, noting that with roughly 67 million Bank Verification Number (BVN) holders already captured in the formal tax net, close collaboration among banks, fintechs and regulators will be essential to ensuring expanded digital identity translates into fairer — not merely more efficient — tax administration.
Historical and Economic Context
The warning lands at a pivotal moment for Nigeria's tax system. The country has been pursuing a significant tax reform agenda in recent years aimed at closing its persistently low tax-to-GDP ratio, a figure that has long constrained government revenue relative to peer African economies despite Nigeria's status as the continent's largest economy by GDP. Low tax-to-GDP ratios have historically limited government capacity for infrastructure investment, social spending and debt servicing, making revenue mobilisation a recurring policy priority across successive Nigerian administrations.
The establishment of the Office of the Tax Ombud itself, under 2025 legislation, reflects a broader institutional recognition that reform sustainability depends not just on legal authority to collect taxes, but on taxpayer confidence that the system operates fairly — a lesson echoed in other African tax administrations facing similar trust deficits.
Why It Matters for Africa
The Tax Ombud's intervention carries implications that extend beyond Nigeria's borders:
Domestic revenue mobilisation across the continent. Nigeria's 8.2% tax-to-GDP ratio, well below the 38-country African average of 16.1%, illustrates a challenge shared by several African economies seeking to reduce reliance on external borrowing and commodity revenue by strengthening domestic tax bases.
Fiscal sustainability and debt management. A more trusted, broader-based tax system directly affects a government's capacity to fund infrastructure and social spending without over-relying on debt — a concern increasingly relevant given elevated debt-service burdens across several African sovereigns.
Digital identity and formalisation. The integration of roughly 67 million BVN holders into Nigeria's formal tax net highlights how digital identity infrastructure is reshaping tax administration across African markets, with implications for how quickly informal economic activity can be brought into formal revenue systems.
Business compliance costs and investment climate. How Nigeria balances enforcement with fairness in its tax reforms will influence business confidence and formal-sector investment decisions, a factor investors weighing Nigerian exposure often monitor alongside currency and monetary policy signals.

For Businesses
Monitor how tax enforcement approaches evolve, as increased scrutiny without corresponding administrative fairness could raise compliance friction.
Engage with formal grievance channels, including the Office of the Tax Ombud, where legitimate tax administration disputes arise.
For Investors

Watch for policy clarity on digital tax identity integration, which could affect formal-sector compliance costs over time.
For General Readers
Understand that a low tax-to-GDP ratio limits government capacity for public services, making broader, trusted tax compliance a shared economic interest.

Conclusion
Dr. John Nwabueze's warning against a revenue-first approach to tax reform reflects a broader tension facing many African economies: the need to expand government revenue without eroding the taxpayer trust that makes sustainable compliance possible. With Nigeria's tax-to-GDP ratio still well below the continental average, how the country balances enforcement with institutional fairness in the years ahead will shape whether its reform agenda delivers durable results.
