What to do if the Canada Revenue Agency reviews your benefits


The Canada Revenue Agency (CRA) may send you a questionnaire or a letter asking for documents to confirm that we have correct and up-to-date information for you. This is to make sure that you get the right amount of benefits and credits.

It's important that you reply and give all the information that the CRA asks for. If you do not reply, your child and family benefits could stop.

Our review could increase or decrease your benefits, depending on your situation. In some situations, you might have to pay back benefits or credits that you have received.

How to send your documents

You or your authorized representative can send your documents in one of three ways:

  • electronically, using Submit documents online
  • by fax, to the number provided in the letter
  • by mail, to the address provided in the letter

Send documents that:

  • are clear and easy to read
  • give the information the CRA asked for
  • cover the entire period under review

For example, if we are reviewing your residency for two years, and you are sending a copy of your property tax bill, you will need to send a copy of the tax bill for each year.

Keep a copy of any receipts, forms and documents that you send to the CRA.

Types of supporting documents

We review information such as marital status, primary care of children and residency. For more information and to see what types of documents the CRA accepts, go to Supporting documents.

Do you need more time or don’t have all your documents?

If you need help or you’re having problems getting the documents we are asking for, or if you need more time to get the documents, call the telephone number provided in the letter or call 1-800-387-1193.

Do you need a copy of the CRA’s questionnaire or letter?

If you need a copy of the questionnaire or letter the CRA sent you, call 1-800-387-1193.

How long does it take to review your documents?

You should hear from the CRA no later than 45 days after it gets all your documents.

After the review is complete

After an adjustment has been made, you can still give the CRA new information to support your claim. There is still time to send us the documents.

Keep your information up to date

To make sure you are getting the right amount of benefits and credits, keep your information up to date with us.

Do you suspect someone is receiving benefits and credits that they should not be getting?

Falsely claiming tax benefits or credits is costly for all Canadians. If you suspect someone is receiving benefits and credits that they should not be getting, you can let the CRA know.
