Company Income Tax (CIT) Estimate for Nigerian SMEs

Short answer: Companies Income Tax is estimated from turnover minus allowable expenses, with size bands at 0% (small company), 20% (medium), and 30% (large). Minimum tax and development levy may apply. Pioneer and export-zone reliefs require a valid certificate.

Company size bands

Planning bands in the calculator:

• Turnover below ₦25m may qualify for 0% CIT if fixed-asset tests are met
• ₦25m–₦100m uses 20% on assessable profit
• Above ₦100m uses 30%

Minimum tax (0.5% of turnover) can apply when profit-based CIT is lower.

Pioneer and free trade zone relief

If you hold a valid Pioneer Status certificate or operate in an export-oriented free zone, you may model relief in the calculator. You must confirm you hold the certificate; relief is not applied without that confirmation.

Export-zone relief typically requires a high export revenue share (75% in this planning model).

Monthly reserve

The result suggests a monthly CIT reserve from annual CIT plus development levy divided by twelve. Use it for cash planning, not remittance scheduling.
