UK Corporation Tax Calculator
Estimate the Corporation Tax for your limited company's accounting period. The calculator applies the 19% small profits rate, the 25% main rate and marginal relief between £50,000 and £250,000. It also adjusts those limits for associated companies and short periods, and covers the Annual Investment Allowance, full expensing and the current R&D schemes. Rates apply to accounting periods from 1 April 2023 onwards.
