2026 planning estimate. Confirm before filing. For accounting periods ending before 1 January 2026, check the official transition guidance.
Rules and assumptions
Uses the National Assembly's January 2026 text: annual turnover up to ₦100 million and total fixed assets up to ₦250 million for small-company treatment; otherwise 30% company income tax and 4% development levy.
The simplified option uses revenue minus expenses for both taxes. The tax-computation option applies 30% to entered total profits and 4% to entered assessable profits. Capital allowances, losses, credits, incentives and minimum effective tax are not calculated.
Older official copies show a different small-company definition, including a ₦50 million threshold and a professional-services exclusion. Confirm the applicable classification before relying on a zero estimate.
