What is Marginal Rate Relief?
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.
Who can claim Marginal Rate Relief?
Your company or organisation may be able to claim Marginal Relief if its taxable profits from 1 April 2023 are between:
£50,000 (the lower limit)
£250,000 (the upper limit)
