It has come to our attention that the CRA XML submission site fails to validate XML submissions when the filer name (transmitter name) contains the "&" character. Until such time as CRA resolves this issue, you can prevent the error by opening the Transmitter Setup dialog in eForms, and replacing "&" with "and" in the "Name line 1" field under "Transmitter Information". You will need to do this once for each eForms user who generates XML files for submission to CRA.
BREAKING: 2025-01-17 - CRA has informed us that they are working to resolve the ampersand issue.
Additionally, due to changes made by CRA to the XML submission process, CRA now requires that XML submissions for previous years must include the 2024 version of the T619 record. We are working with CRA to minimize the impact of this requirement, and will post further details here as they become available.
BREAKING: 2025-01-20 - We are working on a tool to help you apply a 2024 T619 record to a previous year's XML file.
And finally, the XML submission site which was used to upload XML submissions in the past has been deactivated. We have updated eForms accordingly, and CRA has (on our suggestion) updated the deactivated page to redirect filers to the new XML submission site by clicking the "Internet file transfer application - Disclaimer" link, as shown in the image below.
