Nigeria's corporate tax receipts have hit a wall, and the numbers arriving from the NBS make the problem impossible to ignore.

Company Income Tax collections in Nigeria stood at ₦1.37 trillion in Q1 2026, representing an 8.08% decline from the ₦1.49 trillion recorded in Q4 2025, and a steeper 31.05% annual decline compared to Q1 2025, highlighting the pressures facing corporate earnings and tax generation despite strong contributions from financial services, mining, and manufacturing.

Foreign companies dominated the quarter's receipts, contributing ₦828.82 billion, more than 60% of total CIT collections, while domestic companies remitted ₦538.91 billion. The foreigners-over-locals imbalance is not new, but it is sharpening in a quarter when domestic corporate profitability appears to be under particular strain.

The sectoral picture is uneven. Water supply, sewage, waste management, and remediation activities recorded the highest quarter-on-quarter growth at 485.71%, followed by household activities at 197.04%, while agriculture, forestry, and fishing recorded the steepest contraction at -73.52%, and construction fell by -63.15%.

The timing of the fall is explained at least partly by the very reform designed to fix Nigeria's revenue problem. The government implemented a package of tax reforms in 2025, including the Nigeria Tax Bill and related legislation signed into law in June 2025 and effective January 2026, intended to modernise tax administration and broaden the revenue base. In March 2026, the federal government also introduced new presumptive tax rules for micro, small, and medium enterprises.

The paradox is that some of those reforms are cutting receipts before they can build them. Analysts note that some of Nigeria's recently enacted tax reforms would reduce government revenue in the short term because they were designed to support households and small businesses with expanded VAT input credits, additional zero-rated items, and broader exemptions on basic consumption goods, accounting for an estimated 1.7 percentage points of the revenue decline.

The broader non-oil revenue picture reinforces the concern. Companies’ Income Tax, Capital Gains Tax, and Stamp Duties generated ₦3.75 trillion against a target of ₦5.05 trillion in Q1 2026, a shortfall of ₦1.30 trillion and a performance rate of just 74.25%, compared to a 103.74% performance rate in the equivalent period of 2025.

Analysts say the sharp year-on-year decline in CIT collections points to persistent pressure on corporate profitability and the need for sustained efforts to broaden the tax base and improve compliance, particularly among domestic firms.

For an economy simultaneously trying to fund a ₦68 trillion budget, service a ₦15 trillion debt bill, and expand social protection for 63% of the population living below the poverty line, a 31% collapse in corporate income tax receipts in a single year is not a data point; it is a distress signal.
