T4 Box 45 Dental Codes Explained (Codes 1 to 5)
Box 45 on your T4 (box 015 on a T4A) shows the dental coverage your employer offered you on December 31. Code 1 means no access to dental coverage; codes 2 to 5 mean you were offered coverage. It reflects what was offered, even if you declined it.
| Code | Meaning |
|---|---|
| 1 | Not eligible for any dental insurance or coverage |
| 2 | Coverage offered for the employee only |
| 3 | Employee, spouse and dependent children |
| 4 | Employee and spouse |
| 5 | Employee and dependent children |
Things to know
- The code shows what the employer offered, not whether you used it, opted out or refused it.
- Access to an employer-negotiated group rate, even if you pay the full premium, counts as coverage (code 2).
- It is based on your status on December 31.
- Pension payers report the same codes in box 015 of the T4A.
Why it matters: having access to dental insurance can make you ineligible for the Canadian Dental Care Plan.
