Out of pocket medical aid expenses from prior years.

Previously I was a SITE taxpayer and did not have submit an income tax return but I was on a medical aid which I paid out of my own pocket. Currently, I have to submit my income tax return. Can I still claim for these qualifying medical expenses as it is within 3 years. I do have my medical certificates as well from my medical aid. If I can claim should I add this to my current tax return or is there additional forms that I need to complete?

You cannot claim prior year medical expenses in your current tax return.
The only way to claim prior year medical expenses is to file tax returns for the prior years.
I hope this helps.
