Calculate your corporation tax liability based on your net profits

You can use this calculator to find out how much corporation tax your limited company will be liable for, which is based on your net profit before taxes.

From 1 April 2023 the Corporation Tax rate changes to:

• 19% for taxable profits below £50,000 (small profit rate)
• 25% for taxable profits above £250,000 (main rate)

Marginal Relief provides a gradual increase in Corporation Tax rate between the small profits rate and the main rate — this allows you to reduce your rate from the 25% main rate.
