Responding to us

If your income tax and benefit 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 centres will contact you or your authorized representative by telephone or in writing.

When replying to our request for more information:

  • reply within the time frame indicated to the address in our letter
  • include the reference number found at the upper right corner of our letter
  • send us all receipts and/or other documents requested that apply to your situation


If your return has been selected for review by our Pre-assessment Review, Processing Review or Request Verification Program, you or your authorized representative may send scanned documents to us online using My Account for Individuals or Represent a Client. See Submitting documents online – Pre-assessment Review, Processing Review and Request Verification Programs for more information.

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

Submitting information after a review

If your claim was changed 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. See our letter for information about submitting documents.

If you have any questions about a letter received from one of our programs or need more time to send us the information or documents we asked for, contact us at the telephone number found at the bottom of our letter.
