Cancel tax forms sent to CRA/RQ

On occasion, individual tax forms are produced in error. Often, when this occurs, tax forms are re-run. It is important to advise you that if original forms have already been filed with CRA or Revenu Quebec, and you will NOT be filing amended forms to replace them, it is your responsibility to initiate a cancellation request. Your government agency website provides detailed instructions on how to complete this.

As an example, 2024 tax forms have been processed and filed with CRA (100 - T4s and 5 - T4As). It is discovered that the 5 T4As have been produced in error and are not required (the earnings and deductions should be on the T4). You complete the following steps to correct the error:

  1. You make the necessary adjustments to your year-to-dates to move the earnings and deductions from the T4A to the T4. This results in a zero T4A balance.
  2. Your tax forms are re-run (as amended) producing 100 - T4s and 0 - T4As.
  3. You MUST initiate a cancellation request for the 5 invalid T4As.

If Dayforce filed these form(s) on your behalf, contact your Customer Support Team to initiate a cancellation. If you have filed the form(s) directly to CRA/Revenu Quebec, please contact them with your request.

If you do not initiate a cancellation request your totals will be overstated and will not match your annual remittances. This may result in CRA/Revenu Quebec contacting you for clarification.

Note: For Province of Tax errors - A tax form cancellation request must be initiated if the only error on the form is an incorrect province of tax. If you intend, for example, for an employee’s SK form to replace their original MB form (rather than be in addition to the MB form) cancel the MB form. In these limited circumstances, an amendment of the original form is not possible. If you do not initiate a cancellation, the original data for that employee will remain on file with the agency and their total income will be overstated.
