Nigeria Tax Act 2025 · effective 1 January 2026

Model company tax without mixing the old and new regimes.

This local planner applies the enacted 0% or 30% CIT rate to total profits and the 4% development levy to assessable profits. It does not file a return, calculate a section 57 top-up, or replace an accountant’s tax computation.

Company and profit bases

For accounting periods ending before 1 January 2026, use the repealed-law computation—not this calculator.

Used only for the small-company and section 57 review tests.
Small status requires no more than ₦250M.
Enter the tax computation’s total-profits figure after applicable deductions and capital allowances.
Section 59 applies the levy to assessable profits, not the CIT total-profits base.

What changed under the 2026 regime?

What qualifies as a small company?

The enacted definition uses all three tests: gross turnover no more than ₦50M, total fixed assets no more than ₦250M, and no professional-services business. Passing only the turnover test is not enough.

Why are there two profit inputs?

Section 56 charges CIT on total profits. Section 59 charges development levy on assessable profits. A serious estimate must not silently use one number for both.

Where are medium-company 20%, education tax and minimum tax?

Those belong to the repealed framework. This calculator is scoped to the Nigeria Tax Act 2025 from 1 January 2026 and does not blend the regimes.
