Nigeria’s States Generated N5.15tn IGR in 2025, Up 41%
Nigeria’s 36 states and the Federal Capital Territory (FCT) generated a combined N5.15 trillion in Internally Generated Revenue (IGR) in 2025, representing a 40.93% increase from the N3.65 trillion recorded in 2024.
The latest IGR data highlights a significant increase in internally generated revenues across Nigeria’s subnational governments, although revenue generation remains heavily concentrated among a small number of states.
Top 10 states account for nearly 75% of total IGR
The top 10 revenue-generating jurisdictions collectively generated N3.85 trillion in 2025, accounting for nearly 75% of the N5.15 trillion generated by all states and the FCT.
Their combined revenue also increased by 42.67% from the N2.70 trillion recorded in 2024.
The figures indicate that most of the growth in subnational internally generated revenue continues to be driven by a relatively small group of economically larger states.
Lagos remains Nigeria’s top IGR generator
Lagos State retained its position as Nigeria’s largest revenue-generating subnational economy in 2025.
The three leading jurisdictions — Lagos, Rivers and Enugu — generated approximately N2.60 trillion during the year, representing about 50.6% of total IGR generated nationwide.
Lagos alone also generated more IGR than the combined revenue of 22 other states lower down the ranking, underscoring the significant disparity in revenue-generating capacity across Nigeria’s subnational governments.
The concentration of IGR among a handful of states highlights the wide differences in economic activity, formalisation, tax capacity and internally generated revenue potential across Nigeria’s states.
