Step 1: Select Your Company Type

Your annual turnover decides your tax rate. Choose the option that fits your company's sales figures.

  • Regular Company (30% Tax): Select this if your annual turnover is over ₦50 million. This is the standard rate.
  • Small Company (0% Tax): Select this if your annual turnover is ₦50 million or less. Your company is exempt from CIT, which is a major win for small businesses.

Step 2: Input Your Financial Data

You need two key numbers from your accounting records.

  1. Total Profits Before Tax (₦): Enter the profit your company made for the year before applying any income tax. (The tax calculation is based on this figure.)
  2. Annual Turnover (₦): Enter the total sales revenue your company generated for the year. (The tool uses this number to confirm your company size and tax rate.)

Step 3: View the Breakdown

Click Calculate Tax 🚀. The calculator instantly processes the data and shows a full breakdown.

The results provide a clear picture:

  • Company Income Tax (CIT): The main tax, typically 30% of your profits (or ₦0 if you are a Small Company).
  • Development Levy (4%): This levy is a separate charge on your assessable profits, applied alongside CIT for Regular Companies.
  • Total Tax Payable: The sum of all taxes and levies.
  • Net Profit After Tax: This shows your final, true profit.

Note: If your company is very large (turnover of ₦20 billion or more), the tool flags a potential issue. It checks if your effective tax rate meets the required 15% minimum and warns you if you might owe additional tax to cover the shortfall.

Knowing your tax burden ahead of time lets you budget correctly. Which company type are you calculating today: Regular or Small?
