I received a letter from CRA. What should I do?

How to read a CRA letter, check it's real, and respond before the deadline.

A letter from the Canada Revenue Agency can be stressful, but most are routine. Here is how to handle one.

1. Make sure it's really from CRA

Scams are common. CRA will not ask for payment by gift card, prepaid card or cryptocurrency, and will not threaten arrest. Log in to CRA My Account or My Business Account: genuine letters normally appear there too.

2. Identify the type of letter

  • Review or request for information: CRA wants receipts or documents to support a claim, such as medical expenses, tuition or child care.
  • Proposal letter: CRA plans to change your return and gives you a chance to respond first.
  • Notice of reassessment: CRA has changed your return and you may owe more or receive a refund.
  • Collections notice: a balance is overdue.

3. Note the deadline

Most review letters give about 30 days to respond. If you disagree with a reassessment, an individual generally has 90 days from the date of the notice, or one year from the filing due date if later, to file a notice of objection.

4. Respond with the right documents

Send clear copies of exactly what was asked for, organized and labelled. Uploading through My Account is usually fastest.

5. Don't ignore it

If you don't respond, CRA will usually deny the claim and reassess you, with interest.
