The 'Final review' page provides a summary of your Company Tax Return.
If you have any other information that you have not already told us about, such as claims or elections or relevant reports or statements, you may attach these files now. These attachments must be in PDF. The maximum size for the combined files is 3MB.
If you decide not to use the HMRC accounts and computations templates then at this point you will also be prompted to attach your own accounts and computations files to your Company Tax Return.
You are now ready to submit your Company Tax Return.
