Chancellor Kwasi Kwarteng announced a reversal of the planned increase in Corporation Tax in his mini-budget on 23 September 2022. [This proposal was reversed by the Prime Minister on 14 October 2022]

  • Under the previous government’s plans, the rate of Corporation Tax was to increase from 19% to 25% from April 2023 for firms making more than £250,000 profit.
  • This increase has been permanently cancelled. The rate will remain at 19% for all companies, regardless of the amount of profit made.
  • As a result, the rate of Diverted Profits Tax (DPT) which was due to increase to 31% from April 2023 will remain at 25% to retain the 6% difference between DPT and the main rate of Corporation Tax.
