Issue

When uploading a T4 XML file to the CRA, users may encounter the following error message:

Invalid formatting detected in one or more fields.

This issue can be caused by invalid characters in certain fields however CRA is having some parsing problems as well. Despite the warning, the CRA will still accept the submission.


Proceed Despite the Warning

The CRA Support team had advised us that the system does still allow the submission, by using the following steps:


  1. Resend the file a second time
  2. Checking the box that says:

    "I want to proceed without correcting these errors."

  3. Submitting the T4 XML file
  4. Waiting for the confirmation email (typically within a few minutes).


CRA support staff and previous users have advised that despite the warning, the return is accepted successfully.
