📌 Responding to Us — Canada Revenue Agency (CRA)

If your income tax and benefit return is selected for review by one of the CRA’s programs — such as the Pre-assessment Review, Processing Review, Request Verification, or Matching Programs — the CRA will first try to verify your claim with information it already has on file. If more information is needed, you or your authorized representative will be contacted by mail or phone.

📅 What to Do When You Receive a Request

  • 📝 Respond within the timeframe specified in the letter to the address shown.
  • 🔎 Include the reference number found in the upper-right corner of the letter.
  • 📂 Provide all requested receipts and documents that relate to your tax return.

📤 Submitting Your Information

You or an authorized representative can submit scanned copies of supporting documents securely through:

  • 💻 My Account for Individuals
  • 👤 Represent a Client

This online service is a fast and reliable way to send information and keep original documents safe. If documents are unavailable, include a written explanation or call the phone number at the bottom of your letter to explain your situation.

🔄 After a Review Is Completed

If the CRA makes changes to your return after a review and you later find additional supporting documents, you can still submit these for reconsideration. The CRA will review the new information and adjust your return again if appropriate.

📞 Contact Information

If you have any questions about the CRA letter you received or need more time to respond:

  • 📞 Call the number listed at the bottom of the letter (for the Pre-assessment Review, Processing Review, or Request Verification Programs).
  • 📞 For Pre-matching Program queries: call 1-800-263-4747.

📘 Tips for a Smooth Response

  • 📁 Keep clear, legible scans of all documents.
  • 📆 File your response as soon as possible — delays may result in disallowed claims.
  • 🤝 If you need help or more time, communicate with the CRA early.

Responding properly helps ensure your tax return is reviewed quickly and accurately, and that you retain any eligible credits or deductions.
