I recently completed my 2014 tax return and was due a refund. Shortly after I was asked to complete my previous year return. I haven't done it as I was under the impression that I was under the tax threshold (below 250k). Whilst doing the return I noticed my previous employer incorrectly included my travel reimbursement under the wrong code per IRP5 ( they included as non taxable where as it was actually taxable as it was over 8000 km) As a result I have a large amount now owing to SARS. Is there any way for me to deduct actual costs for this if I don't have a log book? I do have a basic summary for the bulk of the expense which I presented to the employer for reimbursement. nb: the cost per km reimbursed is at SARS official rate.
