My client travels approximately 4000 km a month (both business and private). An estimated 20% of his travel is for business. Based on this mileage and his vehicle, which is at the R480,000 threshold, we would like to structure a travel allowance of R20,000 which approximately R4000 is tax-free and R16,000 is taxable. The question is - is there a limit on the travel allowance? Especially since the bulk of it (R16,000) is taxable in any case?
