How to electronically submit DoxCycle documents to the CRA

If you or your client receives a request for documentation from the Canada Revenue Agency (CRA), you may submit those documents electronically via the CRA's website.

Submitting documents for your clients

To submit documents on behalf of your clients, you must be:

  • Registered with Represent a Client.
  • Authorized as a level 2 representative when you file the T1013, Authorizing or Cancelling a Representative form.

You can only use this service when the CRA has sent you or your client a letter requesting documents, and inviting you or your client to use the "Submit documents" service. The letter will include a case number (reference number).

Your clients can also upload their own documents if they are registered for CRA's My Account service. They can log in, click on Submit Documents and enter their case or reference number. 

What types of files can you upload?

The file you upload must be in one of the following formats: .pdf, .doc, .docx, .xls, .xlsx, .rtf, .txt, .jpg, .jpeg, .tiff, .tif, .xps.
