As part of the Canada Revenue Agency’s (CRA) ongoing commitment to improve service delivery by making it faster, easier, and more secure, they have provided information regarding changes planned for July 2025 that impact the Authorization service in the EFILE software for Individuals (T1).
Starting July 15, 2025, all EFILE authorization requests for Individuals will be rejected by the CRA. An error message, T864 from Chapter 11, will be returned to the user, advising them to use the authorization service in Represent a Client instead.
EFILERs will still be able to use Auto-fill My Return, however, the access step in Represent a Client must be completed first.
Note: This change will not impact the authorization requests submitted through EFILE for Business clients.
We will keep updating this article as the CRA provides more information.
