Lagos generated ₦1.87 trillion in internally generated revenue (IGR) in 2025, the highest among the Nigerian states with reported figures used in this article. Enugu followed with ₦406.77 billion, while Oyo and Kano recorded ₦103 billion and ₦102 billion, respectively.
A complete 2025 IGR ranking for all 36 states is not included because the available 2025 figures cover only selected states. The latest complete National Bureau of Statistics (NBS) dataset covers 2024, when Lagos ranked first among the states with ₦1.26 trillion, followed by Rivers with ₦317.30 billion and Ogun with ₦194.93 billion.
Internally generated revenue is money collected by state governments from sources within their jurisdictions. It includes taxes, fees and other revenue collected by state agencies.

Highest And Lowest IGR In 2024
Lagos generated ₦1.262 trillion in 2024, about ₦944.26 billion more than Rivers, which ranked second with ₦317.30 billion.
Ogun ranked third with ₦194.93 billion, followed by Enugu with ₦180.50 billion and Delta with ₦157.79 billion.
The five highest-earning states generated a combined ₦2.11 trillion. Lagos alone accounted for about 34.8% of the ₦3.63 trillion combined IGR reported by the 36 states and FCT.
At the bottom of the ranking, Yobe recorded ₦11.08 billion. Ebonyi followed with ₦13.18 billion, while Kebbi recorded ₦16.97 billion.
IGR Growth In 2024
Enugu recorded the largest percentage increase in the 2024 NBS figures, with IGR rising from ₦33.86 billion in 2023 to ₦180.50 billion in 2024.
Bayelsa recorded 222.96% growth, while Jigawa increased by 115.90%.
Kano grew by 100.03% and Osun by 96.10%. Akwa Ibom increased by 75.47%, followed by Abia at 68.61% and Rivers at 62.38%.
Lagos increased from ₦815.86 billion in 2023 to ₦1.262 trillion in 2024.
The largest percentage increases and the largest absolute increases are different measures. Enugu recorded a very large percentage increase because its 2023 base was much smaller than Lagos’s.
IGR Per Resident
IGR per resident divides a state’s internally generated revenue by its population.
BudgIT’s 2024 figures placed Lagos at about ₦77,869 per resident, followed by Enugu at ₦32,188, Ogun at ₦28,692, Bayelsa at ₦25,912 and Delta at ₦22,497.
The per-resident calculation produces a different ranking from total IGR because states have different population sizes.
IGR As A Share Of Total Revenue
IGR as a percentage of total revenue measures the share of a state’s revenue that comes from internal sources.
Lagos recorded ₦1.87 trillion in IGR and ₦2.6 trillion in total revenue in 2025. Fitch Ratings put IGR at 68% of the state’s operating revenue.
The IGR share should be distinguished from IGR itself. A state can record a large IGR figure while receiving more revenue from FAAC or other sources.
IGR Compared With FAAC
IGR comes from revenue collected within a state, while FAAC allocations come from federally collected revenue distributed among the federal, state and local governments.
Lagos recorded ₦1.87 trillion in IGR and received ₦514.56 billion in net FAAC allocation in 2025. Its IGR was about 3.6 times its net FAAC allocation.
Kano collected ₦102 billion in IGR and received about ₦270.86 billion through FAAC. Its IGR amounted to about 37.7% of its net FAAC allocation.
Oyo recorded ₦103 billion in IGR and received about ₦213.75 billion through FAAC. Its IGR amounted to about 48.2% of its net FAAC allocation.
These comparisons use 2025 figures for IGR and FAAC and should not be mixed with the 2024 NBS ranking.
Methodology And Data
The 2025 section uses reported figures from the states covered by the available revenue reports. It does not represent a complete ranking of all 36 states.
The 2024 ranking uses the NBS dataset covering the 36 states and the Federal Capital Territory.
IGR growth is calculated as:
IGR growth = (2025 IGR − 2024 IGR) ÷ 2024 IGR × 100
IGR per resident is calculated as:
IGR per resident = IGR ÷ population
IGR as a percentage of total revenue is calculated as:
IGR share = IGR ÷ total revenue × 100
The 2025 and 2024 figures come from different reporting sources, as stated above.
