Medical expenses are one of the non-refundable credits. As per our TurboTax article Non-Refundable Tax Credits: A non-refundable tax credit reduces the amount of tax you pay on your taxable income. You will not get money back from a non-refundable tax credit, but you can use it to offset how much you will pay.
For example; If you determine that you owe $1,000 in personal taxes, but you’re also eligible for $500 in non-refundable credits, you’ll only pay $500. However, if you don’t owe any taxes and you are eligible for $500 in non-refundable tax credits, you will not get a $500 refund.
