Canada Dental Care Plan T4/T4A Boxes
To support the administration of the Canadian Dental Care Plan, Canada Revenue Agency (CRA) created the following boxes on tax slips for reporting purposes.
- Box 45 on the T4: Statement of Remuneration Paid
- Box 15 on the T4A: Statement of Pension, Retirement, Annuity and Other Income
A corresponding reporting code (not deduction) will represent the dental coverage an employee had access to under our dental plan as of December 31 of the tax year. “Access” refers to the plan coverage available to an employee and not to the employee’s individual family status or the coverage that may have been elected. For example, the T4 may be coded with a “3” even if the employee has no spouse or dependents.
| Code | Access | |
| 1 | Not eligible to access any dental care insurance or coverage of dental services of any kind | |
| 2 | Payee only | |
| 3 | Payee, spouse, and dependent children | |
| 4 | Payee and their spouse | |
| 5 | Payee and their dependent children |
