Authorize a representative: How to give authorization

Your representative must be a registered electronic filer in good standing. EFILE must be used with CRA certified professional tax software. This gives your representative instant access to your CRA accounts.

Authorization requests can be submitted 21 hours a day, except between the hours of 3:00 am and 6:00 am Eastern Standard Time.

Before submitting an authorization request via EFILE, your representative will ask you to sign a signature page and will keep it in their records. It must be kept for six years following the date that the return was electronically filed. It is a good idea to keep a copy for your records too. Do not send the signature page to the CRA unless we ask to see it. Signature pages sent to the CRA that we have not requested will not be processed or returned.

For more information or to apply for EFILE, go to EFILE for electronic filers.

Your representative can submit an authorization request electronically. You need to be registered for My Account to use this option.

If your representative has a RepID, they can log in to Represent a Client.

After they complete the authorization request, you will need to confirm or deny the request in My Account.

Important: A signature page will no longer be generated as it is no longer required for this option.

Note: If you cannot register for My Account, you will need to provide your representative with information from your notice of assessment from a previous return that was processed at least six months ago. For more information, go to Alternative process for individuals.

To learn more about how you can easily and securely authorize and verify new authorization requests, go to Confirm my representative's authorization request.

Note: A representative cannot submit an authorization request in Represent a Client for a deceased client until we receive and process a copy of the deceased person's last will and testament. For more information, go to Legal representative for a deceased person.
