Oil Revenue & the National Budget
Petroleum has been the backbone of Nigeria's public finances for more than five decades. Oil and gas revenues have historically accounted for 60-80% of total government income and over 90% of foreign exchange earnings, making the annual budgeting process deeply dependent on global crude oil prices and production levels. Understanding how these revenues are collected, pooled, and distributed is essential to grasping the broader dynamics of Nigeria's political economy.
Oil Revenue Dominance
Nigeria's dependence on oil revenue began in earnest during the 1970s oil boom, when petroleum overtook agriculture as the primary source of government income. At its peak, oil revenue accounted for over 80% of federal government receipts. Although diversification efforts have brought this figure closer to 50-60% in recent years, petroleum remains by far the single largest revenue source.
Government oil revenue comes from several streams: royalties paid by producers on extracted crude, Petroleum Profits Tax (PPT) on upstream company earnings, NNPC's equity crude oil sales from joint venture and production sharing contract operations, signature bonuses from licence awards, and gas flaring penalties. Together, these streams feed into the Federation Account - the central pool from which all tiers of government are funded.
This heavy reliance on a single commodity has made Nigeria's fiscal position inherently volatile. When oil prices are high, government coffers overflow and spending expands rapidly. When prices collapse, as they did in 2008-2009, 2014-2016, and 2020, government revenues fall sharply, forcing painful spending cuts, increased borrowing, or drawdowns from savings buffers.
In 2022, oil and gas revenue contributed approximately 50% of Nigeria's total federal government revenue, down from over 70% a decade earlier.[2] This decline partly reflects improved non-oil tax collection, but also reduced oil production due to theft, pipeline vandalism, and underinvestment.
The Federation Account
The Federation Account is established under Section 162 of the 1999 Constitution as the central repository for all revenues collected by the Federal Government (except the proceeds of personal income tax of personnel of the armed forces, the police, the Ministry of Foreign Affairs, and residents of the Federal Capital Territory). Oil revenues, import duties, value-added tax, and company income tax all flow into the Federation Account before being shared among the three tiers of government.
The Revenue Mobilisation Allocation and Fiscal Commission (RMAFC) recommends the formula for distributing Federation Account revenues. The distribution is carried out monthly through the Federation Account Allocation Committee (FAAC), which comprises representatives of the federal, state, and local governments.
Vertical Allocation Formula
The current vertical allocation formula distributes Federation Account revenues as follows: Federal Government receives 52.68%, State Governments collectively receive 26.72%, and Local Government Councils collectively receive 20.60%.[1] These percentages have been subject to periodic review and political debate since the return to democratic rule in 1999.
Derivation Principle
Section 162(2) of the Constitution provides that not less than 13% of revenue from natural resources shall be allocated to the states from which the resources are derived. This 13% derivation principle is applied before the vertical formula, meaning oil-producing states in the Niger Delta - Rivers, Bayelsa, Delta, Akwa Ibom, Edo, Ondo, Imo, and Abia - receive a significantly larger share of oil revenue than non-producing states.
FAAC Monthly Meetings
FAAC meets monthly to review the revenues collected, agree on the amounts available for distribution, and approve the allocations. The meeting outcomes are closely watched as an indicator of the nation's fiscal health. In months when oil prices are low or NNPC remittances are reduced, FAAC allocations to states and local governments shrink, often forcing subnational governments to delay salary payments and cut capital spending.
Oil Benchmark Pricing for the Budget
Each year, the federal government sets an oil benchmark price in the national budget - the assumed price per barrel of crude oil used to estimate expected revenues. The benchmark is deliberately set below prevailing market prices to provide a buffer against price declines. Any revenue earned above the benchmark is meant to be saved in the Excess Crude Account (ECA).
The budget also assumes a target production volume, typically around 1.7-2.0 million barrels per day, and an exchange rate. If actual prices exceed the benchmark, the government earns windfall revenue. If prices fall below it, the government faces a revenue shortfall and must either cut spending, borrow, or draw down savings.
In practice, the gap between budgeted and actual production has widened in recent years due to pipeline vandalism, crude oil theft, and declining investment. Nigeria's actual production has frequently fallen below OPEC quotas and budget assumptions, compounding the revenue challenge even when oil prices are favourable.
In 2023, Nigeria budgeted on an oil benchmark of USD 75 per barrel and production of 1.69 million barrels per day.[5] Actual production averaged approximately 1.2-1.4 million barrels per day for much of the year, resulting in significant revenue shortfalls despite market prices exceeding the benchmark.
NNPC Remittances
The Nigerian National Petroleum Company Limited (NNPC Ltd, formerly NNPC) is the largest single contributor to the Federation Account. As the state oil company, NNPC manages the government's equity interest in joint ventures with international oil companies and receives the government's share of production from production sharing contracts. It sells crude oil on behalf of the federation and remits the proceeds to the Federation Account.
However, NNPC's remittances have been a persistent source of controversy. The corporation has historically deducted its operating costs, fuel subsidy payments, pipeline maintenance expenses, and other charges at source before remitting the balance. This practice, known as "first-line charges," has significantly reduced the amounts available for distribution and has been criticised by civil society groups and state governors as lacking sufficient transparency, according to NEITI audit findings.[6]
The Petroleum Industry Act 2021 converted NNPC into a limited liability company (NNPC Ltd), which is expected to improve transparency by subjecting the company to normal corporate governance standards, external audits, and dividend payments to its shareholder - the federal government. Under this new structure, NNPC Ltd is expected to pay taxes and dividends rather than making opaque "remittances" net of deductions.
Non-Oil Revenue Diversification
Successive Nigerian governments have recognised the dangers of excessive dependence on oil revenue and have launched various initiatives to broaden the tax base. The Federal Inland Revenue Service (FIRS) has intensified efforts to improve collection of Companies Income Tax (CIT), Value Added Tax (VAT), and personal income tax. The introduction of the Tax Identification Number (TIN) system and automation of tax administration have contributed to gradual improvements.
Nigeria's tax-to-GDP ratio remains among the lowest in the world at approximately 6-8%, compared to an African average of around 16% and a global average exceeding 20%.[3] This low ratio reflects widespread informality, weak enforcement capacity, generous tax exemptions, and limited compliance culture. Raising non-oil revenue to reduce oil dependence is a central objective of the Strategic Revenue Growth Initiative and the Medium-Term Fiscal Framework.
Other diversification measures include the expansion of customs revenues through trade facilitation reforms, stamp duty collection on electronic transactions, telecommunications taxes, and levies on luxury goods. While these efforts have shown incremental progress, oil revenue remains dominant in absolute terms and continues to be the swing factor in Nigeria's fiscal performance.
