Can I claim my business travel expenses against source code 3703 if my km travelled exceeded 8000km?

Can I still claim travel expenses as my employer pays for the km I drive with my personal vehicle, the Km exceeded 8000km but on my IRP5 it is under source code 3703? I also kept a logbook.

The amount stated next to code 3703 is regarded as a tax free amount so unfortunately you are not able to claim any expense against it. In order to be allowed to claim a deduction for your travel expenses from SARS you need to ask your employer to change the code 3703 to code 3702.
