The 'Final review' page provides a summary of your client's Company Tax Return.
If you have any other information that you've 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'll also be prompted to attach your own accounts and computations files to the Company Tax Return.
You are now ready to submit your client's Company Tax Return.
