Does company paid health care premiums need to be included in an employees T4?

Hey there, fwood15.

Thanks for reaching out to us here. I'd be happy to provide some information regarding T4's.

T4 slips are a record of funds paid to an employee for tax purposes, I recommend reviewing the guidelines on the CRA website. I also suggest taking a look at this helpful guide about Understanding supported pay types and deductions in QuickBooks Online. 

If you have any other questions, feel free to reach back out here.
