This field also messed me up and it makes no sense to me.
Once I finish my 2023 return, I need to go back and correct my 2022 return. In 2022. In 2022 I verified all my T4 boxes just to make sure I understood what was reported where. My T4 box 38 value is included in in box 14 so I figured I should enter the box 38 value into ufile "stock option benefits included as employment income".
Well that was a mistake. As I'm doing my 2023 taxes now, I see a huge capital loss carried forward from last year.
So in my case, I have to leave the field "Stock option benefits included as employment income(T4 box 38)" blank.
