Transmit Supporting Documents Accompanying a Return

You can attach supporting documents to income tax returns when electronically transmitting returns, to help tax authorities process them.

To attach supporting documents to a T2 or a CO-17 return, proceed in the manner indicated in the topic Attach a file, then select the supporting documents to transmit among the files attached to the return. Supporting documents can also be selected when preparing the return.

Notes:

  • To associate supporting documents with a CO-17 return, the value of the CO-17 EFILE status must be different from "Not Applicable."
  • The password will be required if you try to modify the list of supporting documents of a password-protected client file.
