NETFILE error code 31 means the identification information you are submitting to the CRA via NETFILE doesn't match what they have on file for you. Compare the identification info in TurboTax with:
- Your previous year successfully filed tax return or
- Your SIN card or letter issued by Service Canada
Here's how to check for errors:
TurboTax Online
- From 2024 tax return select Personal info > Edit.
- At Your personal info summary, beside your name, select Edit.
- At Let’s get the rest of your personal info, review your personal info.
TurboTax Desktop
- From the left menu, select Introduction.
- Review the information in that section.
If you can't fix the problem after verifying your personal information, you'll need to print & file your return.
