Converter for Pre-2025 CRA XML Files

Currently Under Development

On January 12, 2026, CRA updated their XML file specifications to require that all XML files, including XML files for years before 2025, must be formatted according to CRA's 2026-01-12 specifications. XML files for Amended, Cancelled and Additional submissions that were prepared by software released prior to January 12, 2026 will be rejected by CRA.

What this means is that from January 12, 2026 onward, CRA will only accept your previous year's XML submission if you've re-formatted your previous year's XML file according to CRA's 2026 XML requirements before uploading it to CRA.

We are currently updating our free conversion utility to convert pre-2025 CRA XML files as necessary to meet CRA's 2026-01-12 XML format. We hope to have the updated tool available the week of January 19, 2026.

Converter for Pre-2025 CRA XML Files

A free utility to update older XML files to CRA's updated specifications

The Canada Revenue Agency (CRA) has introduced significant changes to its 2025 XML file validation requirements. Because these changes have been retroactively applied to prior year XML submissions, they will impact all subsequent XML filings for 2024 and earlier.

What has Changed?

  • January 12, 2026: CRA updated its XML specifications to require that all XML files for tax years prior to 2025 comply with the 2025 XML specifications.
  • January 15, 2025: CRA updated its XML specifications to require that the transmitter information section of all XML files for tax years prior to 2024 comply with the 2024 XML specifications.

How Does This Impact You?

As a result, CRA will now reject all Additional, Amended, and Cancelled XML submissions for prior years unless those files meet the updated 2024 and 2025 XML requirements - even if the original filing had previously been accepted by CRA.

But Don't Worry, We've Made It Easy!

We've created a simple, easy-to-use tool that will:

  • Create a duplicate of your original prior-year XML file
  • Automatically reformat it to meet CRA’s 2024 and 2025 XML specifications
  • Produce an XML file that will pass CRA validation
