Also, you are possibly asking for serious trouble to come pouring down on your head by inventing your own fictitious entries into the T4 screen reporting which do not appear on the Employers actual issued reported T4…
If you have some supporting documentation for the amount that the taxpayer paid as premiums to a PHSP, then the medical expense screen in the place to report it. Alternatively, the taxpayer can request the employer to issue and amended T4, if applicable.
Most employers don’t like amending a T4 just to include the medical premiums paid.
I usually ask my clients for the last pay stub for the period ending on December 31st.
If the medical premiums paid is not clearly marked, then I provide them with an email requesting that the employer confirm in writing the employee amounts paid for each of the following:-
supplementary medical insurance premiums paid by employee as a deduction from net pay
dental insurance premiums paid by employee as a deduction from net pay
health spending account premiums paid by employee as a deduction from net pay
