Validating your application

If your application is selected for review, we may ask for more information to validate your application.

Documents you may need to provide

Keep your receipts for 6 years and make sure your mailing address is up to date. The CRA will contact you by mail if we need more information to validate your eligibility.

You do not need to call us if your child's dental appointment is rescheduled within the same benefit period unless we ask for this information.

If you get a letter from the CRA

You must provide all requested information within 30 days from the date on the letter. If you are found to be ineligible or do not provide the required information, you may have to return any payments you received.

We may request one of the following for each child you applied for:

  • receipt for dental care services
  • invoice for dental care services
  • dental statement of account
  • letter from the dental care provider

Your document must include:

  • name and address of your child
  • name and address of the dental care provider
  • date of the dental appointment
  • cost of the dental care service

The CRA may verify the authenticity of the documents you provide. We may call you or your dental care provider to confirm any information you give us.
