IMF Revenue Reforms: Boosting Nigeria’s Revenue and Trimming Waste as Debt Swells

In a candid assessment released in October 2026, the International Monetary Fund (IMF) urged the Federal Government (FG) to adopt robust IMF revenue reforms and eliminate fiscal waste as the nation’s external debt climbs to unprecedented levels. The Fund praised recent moves to target transport subsidies for the most vulnerable Nigerians, but warned that blanket subsidies remain costly and inefficient. With the debt‑to‑GDP ratio edging higher, policymakers face a tightrope between growth‑stimulating spending and fiscal prudence.

Why debt is a growing concern for Nigeria

Nigeria’s public debt surged past US$200 billion in early 2026, driven by a combination of pandemic‑era borrowing, infrastructure projects, and higher financing costs. While the country enjoys abundant natural resources, the volatility of oil prices continues to expose fiscal buffers. The IMF’s latest staff report highlighted that debt service payments now consume over 15 % of total government expenditure, leaving less room for health, education and social safety nets.

Regional neighbours such as Ghana and Kenya are grappling with similar pressures, but Nigeria’s larger economy means that any fiscal misstep reverberates across West Africa. The Fund cautioned that without decisive action, debt sustainability could deteriorate, raising borrowing costs and potentially triggering a credit rating downgrade.

Key recommendations: IMF revenue reforms and waste reduction

The IMF’s roadmap centres on two pillars: expanding the tax base and tightening public spending. First, the Fund called for a comprehensive overhaul of tax administration, including the digitisation of filing systems, broader use of electronic invoicing, and stricter enforcement against evasion in the informal sector. Strengthening the Federal Inland Revenue Service (FIRS) could raise an additional US$5‑7 billion annually, according to the Fund’s estimates.

Second, the report urged the FG to conduct a systematic audit of all ministries and parastatals to identify redundant programmes, overlapping mandates and procurement inefficiencies. Cutting waste, the IMF argued, is not about slashing essential services but about reallocating resources to high‑impact projects such as power generation, road networks and affordable housing.

Targeted transport subsidies: a model for social protection

One of the more nuanced recommendations was to shift from blanket fuel subsidies to targeted transport assistance. The Fund noted that blanket subsidies have historically cost the treasury billions while benefitting a relatively small segment of the population. By directing cash transfers or vouchers to low‑income commuters, the government can cushion vulnerable households against rising fuel prices without inflating the fiscal deficit.

In practice, this could involve expanding the existing National Transport Card scheme, linking it to the National Identity Management System (NIMS) to ensure only eligible users receive benefits. Pilot projects in Lagos and Abuja have already shown promising results, with reduced commuter costs and lower fuel consumption.

Implications for other African economies

While the IMF’s advice is tailored to Nigeria, its underlying principles resonate across the continent. South Africa, for instance, is wrestling with a sovereign debt level that exceeds 70 % of GDP, prompting calls for similar revenue‑raising measures. Morocco and Egypt have both introduced digital tax platforms that could serve as blueprints for Nigeria’s reforms.

Moreover, the emphasis on targeted subsidies aligns with a broader African trend toward social protection programmes that are data‑driven and cost‑effective. Countries like Kenya and Rwanda have leveraged mobile money ecosystems to deliver cash transfers directly to beneficiaries, reducing leakages and administrative overhead.

Political will and implementation challenges

Implementing IMF revenue reforms will require strong political commitment. Past attempts at tax reforms have faced resistance from powerful interest groups and a fragmented legislative landscape. To overcome these hurdles, the FG must engage civil society, business chambers and state governments early in the reform process.

Transparency will be crucial. Publishing detailed audit findings, setting clear timelines, and establishing independent oversight bodies can build public trust and mitigate accusations of politicisation. The IMF stressed that credibility with international investors hinges on demonstrable progress, not just rhetoric.

Potential impact on the Nigerian naira and inflation

Fiscal consolidation, if executed prudently, could stabilise the naira and temper inflationary pressures. By reducing the need for high‑interest borrowing, the government can lower the domestic debt burden, freeing up space for monetary policy to focus on price stability. In the short term, however, some revenue‑raising measures—such as higher indirect taxes—may exert upward pressure on consumer prices.

Balancing these dynamics will require coordination between the Central Bank of Nigeria (CBN) and the Ministry of Finance. The CBN’s recent policy shift toward a more flexible exchange rate regime could complement fiscal reforms, creating a more resilient macro‑economic environment.

Roadmap for the next 12‑month period

To translate the IMF’s recommendations into tangible outcomes, the FG could adopt a phased approach:

1. Quarter 1 (2026): Launch a nationwide tax digitisation programme, prioritising large corporates and high‑value sectors.
2. Quarter 2 (2026): Conduct a comprehensive waste‑audit across ministries, publishing a public report with recommended cuts.
3. Quarter 3 (2026): Expand the targeted transport subsidy pilot to two additional states, integrating mobile money disbursements.
4. Quarter 4 (2026): Review progress, adjust tax rates where necessary, and present a revised fiscal roadmap to Parliament.

By the end of 2027, these steps could generate an extra US$6 billion in revenue and shave off at least 2 % of the budget from wasteful spending, according to IMF projections.

FAQ

• What is the IMF’s main concern about Nigeria’s debt? The Fund warns that rising debt service costs are crowding out essential public spending and could trigger a credit downgrade if not addressed.
• How will targeted transport subsidies differ from blanket fuel subsidies? Instead of subsidising fuel for all, the government would provide cash or voucher assistance only to low‑income commuters, reducing overall fiscal outlays.
• When can we expect the tax digitisation programme to roll out? The IMF recommends starting the rollout in the first quarter of 2026, with full implementation targeted for 2027.
