Why do my Québec and federal medical expenses differ?
In Québec, you claim your Premium Payable Under the Québec Prescription Drug Insurance Plan (calculated on the Schedule K) as a medical expense for the year that you paid it (i.e., you can claim the premium on your tax return).
However, since the premium is paid in , you can only claim it as a medical expense on your federal return. We’ll do this for you automatically on your federal return.
You can claim your premium, if any, on your federal tax return. Do this in the Medical Expenses section.
