Too many documents

SARS has provision of submitting 20 documents only and I have more than 20 documents. SARS doesn't accept excel with more than 1sheet. I have bank statements, receipts, excels with car logs, medical expenses, donations, depreciation, donation and medical certificates, monthly credit card statements. Please suggest how to submit documents. Thanks

You could try and scan and combine some documents into one document so as to reduce total number of documents.
But be aware that there is a 2mb limit per document.
Alternatively, if this is not possible, you will need to go into a SARS branch and submit manually.
