Nigeria Companies Income Tax (CIT) Calculator

Estimate companies income tax, including the small-company exemption for low-turnover businesses.

This is an estimate for general informational purposes only, not tax advice. Nigeria’s Tax Act 2025 (Section 202) states the small-company turnover threshold as ₦50 million, while the companion Tax Administration Act (Section 147) states ₦100 million — the tax reform committee has publicly clarified that ₦100 million is the intended figure, which this calculator uses, but this drafting inconsistency should be verified with a tax professional given how new the law is.

Small companies with annual turnover up to ₦100 million (and total fixed assets below a specified threshold) are exempt from Companies Income Tax entirely, while larger companies pay a flat 30% CIT rate on taxable profit.

Example

  • With the default values shown above, this calculator returns: Small Company (Exempt)?: Yes — 0% CIT (exempt); Companies Income Tax Due ≈ NGN 0.00.

Frequently Asked Questions

What turnover qualifies as a “small company”?

What CIT rate do larger companies pay?

Companies above the small-company threshold pay a flat 30% Companies Income Tax rate on taxable profit under the Nigeria Tax Act 2025.
