Impact of Canadian Dental Care Plan on Employers: Your Guide to 2023 T4 and T4A Reporting Changes

A small wood piece that says FAQ between two puzzle pieces

As part of Budget 2023, our federal government announced a new Canadian Dental Care Plan (CDCP) to make oral health care accessible to more Canadians.  The CDCP will minimize financial barriers to accessing dental care for Canadians who are uninsured and who have an annual family income of less than $90,000.

The Canadian Dental Care Plan is not meant to replace existing dental benefits offered through employers, pensions, or private plans, but is intended to fill gaps in coverage and complement existing provincial and territorial dental programs.

Employer Responsibilities under the Canadian Dental Care Plan

With the CDCP coming into effect at different times for different groups of people between 2023 and 2025, employers must now disclose specific information about dental insurance or coverage eligibility for their employees on T4 and T4A tax forms effective for the 2023 tax year and going forward on an annual basis. The purpose of this is to provide clarity for the government in the provision of dental benefits based on an individual’s job history should they apply for the Canadian Dental Care Plan.

Changes to T4 and T4A Tax Forms for the Canadian Dental Care Plan

To accommodate these reporting changes, the T4 and T4A slips for the 2023 tax year will feature new elements, each accompanied by unique codes:

  • T4 Box 45: Employer-Offered Dental Benefits
  • T4A Box 015: Payer-Offered Dental Benefits
  • Code 1: No access to any dental care insurance or coverage.
  • Code 2: Access to dental care insurance or coverage for only the payee.
  • Code 3: Access to dental care insurance or coverage for the payee, spouse, and dependents.
  • Code 4: Access to dental care insurance or coverage for the payee and their spouse.
  • Code 5: Access to dental care insurance or coverage for the payee and dependents.


Note: For the calendar year 2023 only, it is not mandatory to fill out the new box when Code 1 is applicable. This policy applies only if all reasonable efforts have been made to comply with the reporting requirements.
