Responding to us

If your tax return has been selected for review under any of the Pre-Assessment Review, Processing Review or Matching programs, we will try to verify the claim based on the information we have on file. If we need more information, a representative from one of our tax centres will contact you by telephone or letter.

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

• send your reply and related documents to the address provided so it is received within the time frame indicated, usually 30 days from the date of the letter;
  
  
• provide all the receipts or other documentation requested. If any of the receipts or documentation needed to support your claim are not available, be sure to include a written explanation or telephone the office listed at the bottom of the letter to explain your situation; and
  
  
• include the reference number listed on the upper right corner of the letter. This number helps us quickly match the information to your tax return.
