I have lived this for several yrs now as a federal government employee who lives in QC but works in ON. I finally (with the helpf od CRA and Rev QC experts figured it out. Here is what you need to know:
1) Private Medical Insurance is a taxable benefit in QC.
2) you will only get an RL-1 if your employer has "offices" in QC.
3) Your RL1 will likely show the same amount in box A and J. This is the taxable value of your Private Medical Insurance.
Some stuff from the T4 doesn't transfer well to your RL-1, so double ck!! When your T4 and RL1 do not match, here is how you align them:
RL1 box A (Employment Income) = T4 Box 14 + RL1 box J
RL1 box C = T4 box 18
RL1 box D = T4 box 20
RL1 box F= T4 box 44
RL1 box N= T4 box 46
RL1 box B1= T4 box 16
RL1 box 235= T4 box 85
