Making changes

You must usually make any changes (‘amendments’) within 12 months of the filing deadline.

You can:

  • use commercial software
  • use HMRC’s free online filing service, if you sent your return this way
  • write to or send a paper return to the Corporation Tax office

HMRC may check for errors in your Company Tax Return.

HMRC may charge you a penalty for errors.
