This error usually happens when the 'digital envelope' for your return has a formatting glitch. Before considering a paper return, please ensure your software is fully updated and check that there are no special characters (like & or extra spaces) in your address or name fields. Most of the time, clearing out any unused blank forms in your 'Tax Tools' will resolve the formatting issue.

Please check your personal information, like your name, address, SIN, etc. Make sure the information matches what the CRA has for you. Hidden characters (like a weird dash or an invisible space) can break the XML formatting.

If you are not sure what they have on file for you, you can call and confirm it with them. 

If you are in Canada or the United States, you can call the CRA at 1-800-959-8281. If you are elsewhere, you can call 613-940-8495. This page has more ways to contact the CRA: Contact the Canada Revenue Agency

If you are still not able to resolve this issue, please contact our phone support team for more assistance.
