On February 20, 2026, the Canada Revenue Agency (CRA) released a new list of electronic filing validation errors and warnings. This list is designed to help filers of information returns better understand the messages displayed in their electronic filing error report, categorized as follows:
- Reject to indicate that the return will be rejected;
- Review to advise filers to review their return for specified errors before submitting; and
- Warning to advise filers to review before the final submission to avoid potential issues.
Filers should:
- Review the updated CRA validation error list in detail;
- Update internal filing procedures and software systems as needed; and
- Ensure staff responsible for electronic filings are informed of these changes.
