Responding to us

If your tax return has been selected for review by one of our programs, we will first try to verify your claim based on the information we have on file. If more information is needed, a representative from one of our tax centres will contact you or your authorized representative by telephone or in writing.

When responding to our request for more information, be sure to:

  • include the reference number found at the upper right corner of our letter;
  • send your reply and all requested documents to the address in our letter within the time frame indicated;

Note: If your return has been selected for review by our Processing Review (PR) program, you or your authorized representative may send scanned documents to us electronically using My Account or Represent a Client. See Submitting documents electronically for more information.

  • provide all receipts and/or other documents requested.

Note: If receipts or documents needed to support your claim are not available, include a written explanation or call the number at the bottom of the letter to explain your situation.

Submitting information after a review

If your claim has been adjusted after being reviewed by one of our programs and you have additional information or documents related to the claim, we will accept all new submissions and review your claim again for a possible adjustment. Send any additional information or documents to the address indicated in our letter or electronically.
