Apparently if a sole prop has a vehicle that is used for business and personal use then there are 2 ways to claim a tax deduction, keep a log book of business travel or keep a record of all vehicle expenses incl repairs and petrol and then claim the percentage back that was business use. The first option of the logbook is the only one I thought was possible, rather laborious though, would much prefer the other option as I already keep a record of all the expenses, is that option allowed by SARS and what records are actually expected?
