How to set up box 45 on 2023 T4

James, Canadian Dental Care Plan (CDCP) is not the same as other employer paid benefits. There is no requirement to put the percentage or dollar amount. 

It is required to select a applicable code, that means your software team should develop a new way to select a list of codes from the drop down list. Could you please check with your manager and provide the correct answer for clients. 

This is the information in CRA site.

The codes to be in the drop down list:

Code 1 - not eligible to access any dental care insurance

Code 2 - payee only

Code 3 - Payee, spouse and dependent children

Code 4 - Payee and spouse

Code 5 - Payee and their dependent children
