First, check it is really from CRA
Scammers copy CRA letters and emails. CRA doesn’t ask for payment by gift card or cryptocurrency, and you can confirm any letter by checking My Account or My Business Account, or by calling CRA at a number you find yourself.
The letters business owners see most
| Letter | What it means | What to do |
|---|---|---|
| Request for information or review letter | CRA wants receipts or support for a claim, often chosen at random | Send exactly what is listed, by the deadline, with a short cover note |
| Pre-assessment or processing review | CRA is checking a return before or soon after assessing it | Same as above; missing the deadline usually means the claim is denied |
| HST review | CRA is checking input tax credits or a refund claim | Provide invoices showing the supplier’s HST number |
| Payroll review (PIER) | CPP or EI deductions look short | Check the employee records; correct and pay if CRA is right |
| Audit letter | A formal audit of income tax, HST or payroll | Call your accountant before the first meeting or reply |
| Notice of reassessment | CRA has changed a return you filed | You generally have 90 days to file a notice of objection |
| Collections notice | A balance is overdue | Pay, or arrange a payment plan before enforcement starts |
How to respond well
Find the deadline
It is usually on the first page. If you need more time, ask before it passes.
Send only what is asked
Organized, labelled copies. Never originals, and no long explanations CRA didn’t request.
Keep a record
Note what you sent, when and how, and keep copies.
Get help early
Once you authorize your accountant through CRA’s Represent a Client, CRA can deal with them directly.
We have handled CRA reviews and audits for clients for more than 25 years. See CRA audit help.
Common questions
How long does CRA have to reassess me?
For individuals and Canadian-controlled private corporations, normally three years from the original notice of assessment, four for other corporations. There is no limit where there was carelessness, neglect, wilful default or fraud.
Should I just pay what CRA says I owe?
Not without a review. Adjustments are often reduced when the right records are provided, and you can object. Paying can still make sense to stop interest.
Can my accountant talk to CRA for me?
Yes. Authorize them through Represent a Client, and CRA can discuss your file with them.
