CIT calculator + small-company checker
Work out your companies income tax and development levy, and find out whether you are a small company — for each tax separately, because the two Acts do not agree.
Your company's figures never leave your device. This calculator runs entirely in your browser. Nothing you type is sent to us, logged, or stored — there is no server to send it to.
Your company
Accountancy, law, consulting, engineering, medicine and similar practices.
Professional-services firms are excluded from small-company treatment regardless of turnover.
Your profit
Enter your turnover and assessable profit on the left. We will tell you what you owe, and whether you count as a small company — separately for income tax and for VAT.
Two Acts, two definitions of “small”
The Nigeria Tax Act s.202 sets the small-company turnover cap at ₦50,000,000 for income tax. The Nigeria Tax Administration Act s.147 sets it at ₦100,000,000 for VAT. Both are gazetted and both are in force, so a company turning over ₦75 million charges no VAT and still pays 30% companies income tax on its profits. Most published summaries quote ₦100,000,000 for both taxes, which is how companies in that band end up filing nothing and discovering the mistake later. We apply each cap to its own tax and show you both.
Common questions
- What is the company income tax rate in Nigeria in 2026?
- Small companies pay companies income tax at 0%, while large companies pay 30%. Which one applies turns on your turnover and fixed assets, not your profit.
- What counts as a small company for company income tax?
- For income tax, a small company is one with annual turnover at or below ₦50,000,000 and fixed assets at or below ₦250,000,000. Such a company pays 0% companies income tax, though a separate ₦100,000,000 threshold governs VAT.
- What is the development levy on companies?
- The development levy is 4% of a company's assessable profit — the profit before capital allowances. Small and non-resident companies are exempt from it.
