Ever wondered how far back the CRA can actually audit you?
For most people and small corporations, the answer is three years from your notice of assessment (four for larger corporations). After that, the year is usually closed β unless there was a careless mistake or misrepresentation, which reopens it with no time limit.
That's one of several things worth knowing before you respond to a CRA letter. The biggest one: there's no accountant-client privilege in Canada, so what you tell your accountant isn't protected the way a conversation with a lawyer is.
We put together a plain-English playbook for the first 48 hours after the letter arrives.
