Question to the HM Treasury:

To ask the Chancellor of the Exchequer, whether he has made an estimate of the number of large businesses paying into the highest bracket of corporation tax in calendar years (a) 2022 and (b) 2023.

When the Corporation Tax rate change was announced at Budget 2021 it was estimated that around 200,000 companies would pay the 25% rate. https://www.gov.uk/government/speeches/budget-speech-2021

Estimates of actual numbers paying the main rate will be published once data is available.
