The 36 states and the Federal Capital Territory (FCT) made a total of N5.15 trillion in internally generated revenue (IGR) in 2025, according to the National Bureau of Statistics (NBS).
This amount reflects a 40.93 percent rise from the N3.65 trillion reported in 2024, based on recent data from NBS.
The statistics show that Lagos was the biggest contributor, bringing in N1.77 trillion. Rivers, Enugu, the FCT, and Ogun also made over N250 billion each.
These numbers are part of the NBS’ 2025 Internally Generated Revenue at State Level report, which was released on Thursday.
Lagos Leads the Way
Lagos generated N1.769 trillion in 2025, making up about 34 percent of the total IGR for the 36 states and the FCT.
This is an increase from ₦1.26 trillion in 2024, showing a rise of around 40 percent year-on-year.
Rivers came next with N428.42 billion, up from N317.30 billion in 2024. Enugu generated ₦406.77 billion, more than doubling its ₦180.50 billion from the previous year.
The FCT brought in N356.34 billion in 2025, rising from ₦282.36 billion in 2024.
Ogun recorded ₦252.36 billion, compared to ₦194.93 billion the year before.
The data shows that while revenue grew across the board, most IGR still came from a few state governments.
Understanding the Numbers
The NBS divides IGR into two main sources: tax revenue and revenue from Ministries, Departments and Agencies (MDAs).
Tax revenue includes Pay As You Earn (PAYE), direct assessment, road taxes, stamp duties, capital gains tax, withholding tax, and other taxes collected through local governments.
In its 2024 report, the NBS noted that the 36 states and the FCT generated ₦3.63 trillion, marking a 49.7 percent increase from ₦2.43 trillion in 2023.
Lagos made up ₦1.26 trillion of the 2024 total, with Rivers at ₦317.30 billion and the FCT at ₦282.36 billion. Ogun and Enugu had ₦194.93 billion and ₦180.50 billion, respectively.
The 2024 data also showed that tax revenue made up about 73.35 percent of total IGR across the country, with PAYE contributing ₦1.86 trillion or 69.84 percent of total tax revenue.
One major change in the 2025 figures is Enugu’s revenue growth.
The state’s IGR jumped from ₦180.5 billion in 2024 to ₦406.77 billion in 2025, which is an increase of about 125 percent.
The agency reported that tax revenue for Enugu was ₦51.52 billion, compared to ₦30 billion in 2024.
The latest NBS data positions Enugu among the states with the highest IGR growth in this reporting period.
Dependence on Federal Allocations
The growth in IGR comes at a time when Nigerian states face wider financial challenges. Many still rely heavily on allocations from the Federation Account to fund their budgets.
Another report by PREMIUM TIMES, based on BudgIT’s State of States analysis, revealed that 35 states had a combined revenue of N17.2 trillion in 2024. Yet, 29 states depended on Federation Account allocations for at least half of their income.
