Nigeria’s Revenue Gap Deepens: Why Rising Oil Earnings Cannot Keep The Federal Government Afloat
By OBIOMA TORI
A Stronger Revenue Performance, but a Wider Fiscal Problem
NIGERIA’S public finances are facing a difficult contradiction. Although the Federal Government collected more revenue in the second quarter of 2026 than it did in the preceding quarter, the improvement was not enough to meet its budget expectations. Consequently, the government remains under pressure to borrow to finance infrastructure, security, public obligations and other expenditure commitments.
The figures published by the Central Bank of Nigeria (CBN) reveal the scale of the challenge. Gross federally collected revenue rose by 13 per cent quarter-on-quarter to ₦10 trillion in the second quarter. On an annual basis, the collection increased by 21 per cent, supported by stronger oil receipts, higher crude oil production and contributions from non-oil sources.
Nevertheless, the improvement concealed a substantial revenue deficit. Against an implied quarterly budget target of ₦18.3 trillion, the government collected only 55 per cent of the expected amount. That left a shortfall of approximately ₦8.3 trillion.
Although the ₦10 trillion collection represented the second-highest quarterly revenue performance in recent periods, behind the ₦11.9 trillion recorded in the third quarter of 2025, it still exposed the distance between fiscal projections and actual government earnings.
That gap matters because the Federal Government must finance an extensive range of responsibilities. Beyond infrastructure development, it must meet security requirements, fund public institutions, honour existing obligations and service accumulated debt. Therefore, when revenue falls significantly below expectations, the government must either adjust its spending plans, find additional income or borrow more to sustain its commitments.
Oil Revenue Rises, but the Gains Remain Insufficient
The petroleum sector provided the strongest boost to federally collected revenue during the quarter. Oil receipts increased by 53 per cent to ₦3.8 trillion, compared with the first quarter of 2026.
Higher royalty payments accounted for an important part of that improvement. Royalty receipts climbed to ₦2.4 trillion from ₦1.6 trillion in the preceding quarter, reflecting stronger earnings from crude oil sales.
Meanwhile, international oil prices provided a favourable environment for government revenue. Nigeria’s Bonny Light crude averaged approximately $108.40 per barrel during the second quarter, significantly above the $81.50 recorded in the first quarter.
Domestic production also improved. Crude oil output, including condensates, rose to 1.72 million barrels per day from 1.55 million barrels per day. Together, higher prices and increased production strengthened the contribution of petroleum receipts to the Federation’s revenue.
However, the gains did not translate into the level of income anticipated in the budget. Oil revenue remained considerably below its quarterly target of ₦9.4 trillion. More importantly, Petroleum Profits Tax (PPT) collections amounted to only ₦683 billion against a budget projection of ₦5.1 trillion.
This difference exposes a significant weakness in the revenue outlook. Even when international prices improve and production increases, the government cannot automatically assume that every oil-related revenue stream will perform as projected.
The shortfall in PPT collections therefore limited the benefit of stronger royalties and other oil receipts. In effect, favourable market conditions offered temporary relief without resolving the deeper problem of revenue mobilisation.
Non-Oil Revenue Carries the Greater Share
While oil receipts recorded the strongest quarterly growth, non-oil revenue remained the largest contributor to the government’s income.
Collections from non-oil sources declined by two per cent quarter-on-quarter to ₦6.3 trillion. Nevertheless, they represented approximately 63 per cent of total federally collected revenue during the period.
That contribution demonstrates the growing importance of taxation and other non-oil sources in supporting public finances. It also reinforces the need for Nigeria to broaden its revenue base rather than depend excessively on the unpredictable performance of crude oil.
Yet, the non-oil figures reveal their own weaknesses. Value Added Tax (VAT), the largest contributor within this category, generated ₦2.2 trillion despite declining by 17 per cent from the preceding quarter. The amount represented approximately 35 per cent of non-oil collections.
Companies Income Tax (CIT), by contrast, performed more strongly. Receipts increased by 19 per cent quarter-on-quarter to ₦2.1 trillion, making the tax the second-largest non-oil revenue contributor.
The contrasting performances of VAT and CIT illustrate the uneven character of revenue mobilisation. Although stronger corporate tax receipts helped cushion the decline in VAT, the overall non-oil collection still failed to meet the government’s broader fiscal expectations.
Consequently, the figures point to the importance of improving tax administration, strengthening compliance and ensuring that the government captures revenue due from economic activities across different sectors.
The First-Half Figures Reveal the Scale of the Challenge
The revenue problem becomes more pronounced when the first six months of 2026 are considered.
Total federally collected revenue stood at ₦18.9 trillion during the first half of the year. A simple annualisation of that performance produces an indicative full-year run-rate of approximately ₦37.8 trillion, substantially below the implied annual budget target of ₦73 trillion.
The gap suggests that the government would need a significant acceleration in revenue collection during the second half of the year to approach its budget assumptions.
Achieving that level of improvement would require stronger oil receipts, more effective tax collection and better revenue administration across government agencies. However, the size of the deficit raises questions about whether incremental improvements alone can deliver the required increase.
More importantly, the government must distinguish between temporary revenue gains and sustainable improvements. Higher crude prices can strengthen receipts in a particular quarter, but international prices remain exposed to geopolitical developments, global demand and other market forces.
Similarly, increased production can improve earnings, but the government must also address weaknesses in the collection of taxes and other petroleum-related revenue. Without improvements across these areas, the country risks repeating the same pattern of optimistic projections followed by disappointing collections.
Borrowing Becomes an Increasingly Important Financing Option
When government revenue falls below budget expectations, borrowing often becomes one of the available ways to bridge the financing gap. Nigeria’s persistent revenue deficits therefore place additional pressure on the Federal Government’s domestic and external borrowing strategy.
Domestic borrowing can provide funds through government securities and other debt instruments. However, sustained heavy issuance may increase the government’s debt-service burden and compete with private businesses for funds in the financial system.
That competition matters because businesses also need access to affordable credit to expand production, create jobs and invest in economic activities. If government borrowing absorbs a substantial share of available funds, private-sector financing could face additional pressure.
External borrowing presents another option, particularly where the government seeks funding for infrastructure and other major projects. Nevertheless, foreign-currency loans introduce exchange-rate risks and future repayment obligations.
A depreciation of the naira can increase the domestic-currency cost of servicing external debt. Therefore, the government must carefully assess the terms, purposes and repayment capacity associated with new loans.
Furthermore, borrowing does not eliminate the underlying revenue problem. It provides financing, but it also creates obligations that future budgets must accommodate. When revenue remains weak, debt servicing can consume a larger share of available resources, leaving less room for development expenditure.
States & Local Governments Also Feel the Pressure
The consequences of weak federally collected revenue extend beyond Abuja.
Nigeria’s states and local governments depend heavily on allocations from the Federation Account to finance salaries, infrastructure, healthcare, education and other essential services. Therefore, the performance of federal revenue collection has direct implications for subnational governments.
When federally collected revenue improves, the larger pool of resources can support allocations to the three tiers of government. Conversely, persistent collection weaknesses can constrain the resources available for distribution.
Although the Federal Government faces its own financing obligations, states must also manage competing expenditure demands. They need to maintain roads, pay workers, provide public services and respond to the needs of their communities.
Consequently, the national revenue challenge can affect public-service delivery across the federation, particularly where state governments have limited independent revenue sources.
A More Realistic Revenue Strategy Is Essential
The second-quarter figures offer some encouragement because total collections increased and oil receipts benefited from improved prices and production. However, the ₦8.3 trillion gap between actual revenue and the quarterly budget target shows that the improvement has not resolved the fiscal challenge.
The government therefore faces the task of strengthening revenue administration while making its budget assumptions more realistic.
First, tax compliance must improve. Authorities need effective systems to identify taxable activities, reduce leakages and ensure that businesses and individuals meet their obligations under existing laws.
Second, oil revenue collection requires closer attention. Stronger production and favourable crude prices should translate into more dependable public income, supported by transparent accounting and effective administration.
Third, budget planners must use credible revenue assumptions. When projected earnings consistently exceed actual collections, expenditure plans become vulnerable to financing gaps and repeated adjustments.
Ultimately, Nigeria’s fiscal stability cannot depend on occasional increases in crude oil prices. A sustainable revenue system must draw strength from a broader productive economy, efficient tax administration and accountable management of public resources.
Without those improvements, the Federal Government will continue to confront difficult choices: borrow more, postpone or reduce expenditure, or combine both approaches. The central challenge, therefore, is not simply how to finance the next budget deficit, but how to build a revenue system capable of reducing the need for repeated borrowing.
