Save all you medical related expense receipts. Everything from medication to nursing home fees, and even medical insurance for a trip or wintering in another country is considered eligible. Medical expenses are reduced by a percentage of your income, so it is usually more beneficial for the lower income spouse to claim them. And if you had to travel (more than 40kms) to obtain medical treatment that was not available where you live, you may be able to claim the cost of transportation, meals and accommodation.
