Last year a friend of mine registered me on eFiling so this year I went through a tax practitioner to claim for the first time. The lady claimed for medical and I don't have a medical aid. Then SARS phoned me and said they needed my medical certificate to be submitted within 21 day otherwise they are going to give me a penalty but I don't have medical aid and now they are thinking I was being dishonest and selected me for an audit. I am so scared now as its the first time I am claiming. What must I do?
