LAGOS — Lagos State has maintained its overwhelming dominance in Nigeria’s internally generated revenue (IGR) landscape, recording ₦1.17 trillion in the first half of 2026, according to data released by StatiSense and referenced by Agora Policy.

The figure places Lagos far ahead of Ogun State, which ranked second with ₦140.58 billion, while Enugu State came third with ₦95.61 billion.

The data, covering 32 states and excluding Delta, Edo, Osun and Rivers, highlights the significant differences in the capacity of Nigerian states to generate revenue internally and sustain public spending without relying heavily on federal allocations.

Other states in the top 12 include Kano with ₦60.14 billion, Oyo with ₦55.47 billion, Kaduna with ₦55.16 billion, Akwa Ibom with ₦51.42 billion, Kwara with ₦39.12 billion, Abia with ₦35.68 billion, Niger with ₦33.23 billion, Katsina with ₦33.14 billion, and Cross River with ₦30.68 billion.

Lagos’ Exceptional Revenue Advantage

Lagos’ performance stands out dramatically from the rest of the country. Its ₦1.17 trillion IGR is more than eight times Ogun’s ₦140.58 billion, the second-highest figure in the dataset.

More significantly, Lagos alone generated more internally than the other 31 states combined within the dataset. This underscores the extraordinary economic concentration around Lagos, driven by its large formal and informal business ecosystem, commercial activity, property market, financial sector, corporate headquarters, technology industry, ports-related activities and enormous consumer market.

The figures also demonstrate the extent to which economic activity and revenue-generating capacity remain concentrated in a relatively small number of Nigerian states.

What the Figures Mean for the Nigerian Economy

The IGR figures provide more than a ranking of states; they offer an insight into the structural strength of state economies.

States with stronger internally generated revenue generally have greater capacity to finance infrastructure, education, healthcare, transportation, security and other public services without depending entirely on allocations from the Federation Account.

Lagos’ performance therefore gives the state considerable fiscal space to undertake large-scale projects and maintain public services. However, the huge gap between Lagos and most other states also raises questions about the uneven distribution of economic opportunities across Nigeria.

Ogun’s second-place position is particularly significant. With ₦140.58 billion, the state is benefiting from its proximity to Lagos, expanding industrial clusters, manufacturing activities, logistics networks, real estate development and growing commercial communities.

Enugu’s ₦95.61 billion is also notable because it places the South-East state ahead of several much larger states by population and geographic size. The performance suggests growing revenue mobilisation and expanding formal economic activity within the state.

A Wider Economic Message

The figures point to a central challenge facing Nigeria’s federal system: many states still have limited capacity to raise sufficient revenue from their own economies.

Where internally generated revenue remains low, state governments are more vulnerable to fluctuations in federal allocations. This can constrain long-term planning and make it difficult to sustain major infrastructure and social programmes without external funding.

The disparity also suggests that states seeking stronger fiscal independence need to broaden their economic bases rather than relying primarily on taxation.

Expanding manufacturing, agriculture, technology, tourism, real estate, logistics, services and small and medium-sized enterprises could create a larger taxable economic base while simultaneously generating employment.

For Nigeria as a whole, the ultimate objective should not simply be to increase tax collection. States need to create environments where businesses can grow, workers can earn more and productive economic activities can flourish. A larger and more formal economy would ultimately provide governments with a broader and more sustainable revenue base.

Fiscal Federalism Under Spotlight

The H1 2026 figures are likely to further fuel discussions around fiscal federalism and the financial independence of Nigeria’s states.

A state that can generate substantial revenue internally has greater flexibility to determine its development priorities. Conversely, states with very low IGR may remain heavily dependent on federal transfers, limiting their fiscal autonomy.

The data therefore presents both an opportunity and a warning.

Lagos demonstrates what a highly productive and commercially concentrated state economy can generate, while the wide gap between the leading state and many others highlights the urgent need for broader economic development across Nigeria.

The real economic question is no longer simply how much revenue states collect, but how effectively they can transform their economic potential into sustainable internally generated wealth.
