Converter for Pre-2025 CRA XML Files

On January 12, 2026, Canada Revenue Agency introduced significant changes to its XML file validation process, now requiring that all subsequent XML submissions (for the current year and all previous years) must comply with the new requirements.

What has Changed?

As of January 12, 2026, CRA requires that the Transmitter Information (T619) portion of all XML submissions (whether Original, Additional, Amended or Cancelled) must comply with CRA's 2025 XML specification.

How Does This Impact You?

CRA will reject any XML submissions in which the Transmitter Information record does not comply with CRA's updated XML requirements. Older software which cannot be updated to this XML specification will not be able to create a valid XML submisison.

But Don't Worry, We've Made an Easy Fix!

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 2025 XML specification
• Produce an XML file that will pass CRA validation

Even Better, the Tool is 100% Free, for Everyone!

You don't need to use AvanTax eForms to use this tool. It requires no installation and it is completely free to anyone needing to update 2024 and earlier CRA XML submissions.

The conversion tool can reformat the Transmitter Information section of any CRA XML file; even if that XML file was created by a solution other than AvanTax eForms.

Whether you’re correcting past filings or supporting clients with amended returns, our free XML reformatting tool ensures that your submissions are compliant with CRA's XML specification - without needing to re-enter any data or update legacy software.

If you have questions or would like help getting started, call on us, we’re here to help.

• eForms 2025.105 (2026-01-13) and later comply with CRA's 2025‑01‑15 and 2026‑01‑12 XML specifications; XML files created with eForms 2025.105 and later will be accepted by CRA and do not require conversion
• eForms 2025.105 (and earlier) do not include CRA's 2026‑01‑12 XML specification; users of eForms 2025.105 and earlier should install eForms 2025.106 to ensure compatibility with CRA's XML requirements
