If I get car allowance as part of my total guaranteed package. Can I still claim travel?

My job requires a lot of travelling, I do have a car allowance that is part of my total guaranteed package. I do get reimbursed for the km's traveled and toll fees. Do I still have to complete km as per log book to SARS. Do I further qualify for a tax return in this regard?

What source code appears on your IRP5, 3702 or 3703?

3703 arrears

This is a non-taxable source code so you will not have to worry about completing a logbook or even doing anything on your tax return. You have not been paying more tax because of this.
