How to calculate company income tax in Nigeria
First check whether the company is a small company. If it isn't, company income tax is 30% of taxable profit and the development levy is 4% of assessable profit.
- 1
Check the small company tests
Turnover of ₦100 million or less, fixed assets of ₦250 million or less, and no professional services. Pass all three and CIT is 0%, with no development levy.
- 2
Work out taxable profit
Income minus allowable expenses and capital allowances, adjusted for items that aren't deductible for tax.
- 3
Apply 30% company income tax
Taxable profit × 30% for companies that aren't small.
- 4
Add the 4% development levy
Assessable profit (before capital allowances and losses) × 4%. It replaced four older levies from 2026.
- 5
File within 6 months of year end
The return and payment are due within six months after your financial year end: 30 June for a December year end.
Worked example: consultancy with ₦85m turnover
| Turnover | ₦85,000,000 |
|---|---|
| Professional services? | Yes, so not a small company |
| Taxable profit | ₦12,000,000 |
| Company income tax (30%) | ₦3,600,000 |
| Development levy (4% of ₦12m) | ₦480,000 |
| Total | ₦4,080,000 |
The same company doing non-professional work (such as a creative agency), with assets under ₦250m, would pay 0%.
