I’m not an accountant so this is not tax advice but if you have a spouse or common-law partner, you can have that person claim your medical expenses under their tax return. It will reduce their payable taxes or maybe result in a refund.
Last year I had zero income as my LTD is non-taxable, but I had a ton of medical expenses. When my accountant did my taxes recently, he added all my medical expenses onto my husband’s tax return. ie. my accountant combined my husband’s medical expenses with mine, and entered the total amount onto my husband’s tax return. If you file your taxes yourself, I’m not sure about the T1-ADJ and whether it would be worth the effort. I prefer to pay an accountant to save me the headache of all this stuff.
