The 36 states of the federation and the Federal Capital Territory generated a combined N5.15 trillion in Internally Generated Revenue (IGR) in 2025, representing a 40.93 per cent increase over the N3.65 trillion recorded in 2024, according to the National Bureau of Statistics.
The NBS, in its 2025 Internally Generated Revenue at State Level report released on Thursday, said Lagos remained the highest revenue-generating jurisdiction, with N1.769 trillion generated during the year. The figure represented about 34 per cent of the combined IGR of the 36 states and the FCT.
Rivers followed with N428.42 billion, while Enugu recorded N406.77 billion. The FCT generated N356.34 billion, while Ogun State recorded N252.36 billion.
Ogun’s 2025 IGR represents an increase from the N194.93 billion recorded in 2024, according to the NBS data. The state was therefore among the jurisdictions that generated more than N250 billion during the year.
Lagos’ IGR also rose substantially from N1.26 trillion in 2024 to N1.769 trillion in 2025, while Rivers increased from N317.30 billion to N428.42 billion. Enugu recorded one of the largest increases, rising from N180.50 billion in 2024 to N406.77 billion in 2025.
The NBS categorised IGR into tax revenue and revenue generated by Ministries, Departments and Agencies. Tax revenue includes Pay As You Earn, direct assessment, road taxes, stamp duties, capital gains tax, withholding taxes, other taxes and local government revenue.
The latest figures show that internally generated revenue continued to be concentrated among a relatively small number of states and the FCT, with Lagos alone accounting for more than one-third of the combined total.
The increase in IGR comes against the continuing fiscal challenge facing many state governments, which still depend substantially on allocations from the Federation Account to finance their budgets.
