Dental Benefits Codes must be set in order to genertate T4's from year 2023 on.
This will need to be set for any employee that has timecards in that year even if they are marked as terminated or on leave.
Dental Benefits can be set on the bottom of the Amounts tab of the Employee record.

2 = Payee only
3 = Payee, spouse and dependent children
4 = Payee and their spouse
