Tax Guide/CRA notices
The golden rule for CRA letters
Updated November 4, 2026
Do not ignore a CRA letter, even if you think it is wrong. Most issues are easier to fix before a deadline passes.
A simple process
- Confirm it is real in My Account.
- Note the deadline and reference number.
- Work out what the CRA wants and why.
- Reply with copies, and keep the originals.
- Ask for help if the amount is large or you are unsure.
If you are a Wright Tax client, send the letter through the portal.
