Tied to the Tap: How Nigerian States Depend on Federal Transfers

Across the states where granular budget data exists, internally generated revenue ranges from 51% of revenue down to barely 2% — same federal lifeline, radically different self-reliance.

Executive Summary

Nigeria’s state finances rest on a large vertical fiscal imbalance: states carry heavy spending responsibilities, but the strongest tax handles and the largest shared revenues remain concentrated at the federal level [1][3]. In practice, statutory allocation and VAT receipts — distributed from the Federation Account (FAAC) — are the financial backbone of most states, while internally generated revenue (IGR) is decisive in only a small group of commercially deep, administratively stronger states [1][2].

Kanari’s analysis of state budget documents quantifies that divide directly. Across the six states for which granular line-item budgets could be reconciled, IGR finances anywhere from 51% of combined own-plus-transfer revenue down to about 2% [1]. Anambra, in the commercial South-East, raises roughly as much itself as it receives from Abuja. Borno, in the conflict-affected North-East, raises barely two naira of its own for every hundred it spends [1]. The contrast is not random — it tracks economic structure, urbanization, and the strength of each state’s revenue institutions [2][3].

Key findings:

• IGR self-reliance ranges from 50.8% (Anambra) to 2.1% (Borno) across the six states analysed — a spread of nearly 49 percentage points, with an average of about 23% [1]. The typical state in the sample funds roughly 77% of its revenue from federal transfers rather than its own tax effort.
• The dependency gap is starkest in the North-East. Bauchi (90.5% transfer-dependent) and Borno (97.9%) are almost entirely funded from Abuja, while Anambra (49.2%) is the closest to fiscal balance [1].
• Federal transfers are the larger revenue source in all but one of the six states, ranging from ₦36.3bn (Ebonyi) to ₦116.1bn (Borno) — and in the most dependent states they dwarf own revenue by an order of magnitude. Anambra is the lone exception, where own revenue (₦65.3bn) slightly exceeds federal transfers (₦63.3bn) [1].
• Own-revenue capacity diverges enormously, from ₦65.3bn (Anambra) to ₦2.5bn (Borno) — a 26-fold gap that mirrors the difference between a diversified commercial economy and a thin, conflict-disrupted one [1].
• Lagos sits in a class of its own. Though outside this budget sample, Lagos is the documented national outlier, generating the highest IGR of any state and roughly 30% of all states’ IGR combined — financing the majority of its budget internally [2].

1. The Fiscal Logic: Why Nigerian States Differ So Much

Fiscal-federalism theory predicts exactly the pattern Nigeria exhibits [3]. In federations, subnational governments typically face more spending obligations than revenue-raising authority — a vertical fiscal imbalance — so transfers are normal. What varies is how far a state can offset that dependence with its own revenue effort [3].

In Nigeria that offset is highly uneven because the underlying tax base is highly uneven [2]. States with large urban markets, concentrated formal employment, significant property values, and stronger administrative systems collect far more PAYE, levies, and fees. States without those features stay tied to statutory allocation and VAT sharing [2]. Three forces explain most of the divergence:

• Economic structure. Diversified, service-heavy, commercially dense economies produce stronger IGR; narrow or agrarian economies do not [2].
• Administrative capacity. Autonomous revenue agencies, digital collection systems, and tighter cash management raise effective tax yield [3].
• The oil-transfer incentive. Because oil-linked federation revenue arrives automatically through FAAC, the political urgency to build local tax systems has historically been weak — a soft-budget-constraint effect [4].
