What's error code 31?

Error code 31 is due to a Canada Revenue Agency (CRA) issue affecting all tax software in Canada.

It means the information sent to the CRA doesn't match what's currently on record, which was provided by Service Canada. If you can't fix the problem after verifying your ID, you'll need to file a paper return and include all the necessary slips and receipts.

Note: Your account will be locked after five unsuccessful attempts.
