How do I reimburse an employees mileage in a payrun? The ATO say I need to list it in the reimbursement section, not in gross wage. I can't find how to do this in QB

From the ATO website, I believe the mileage reimbursement needs to be listed on the payslip as it's tax deductible up to a point. We also pay above the ATO reimbursement rate, so I think I'm supposed to do one entry for km reimbursed at ATO rate ($0.72/km), and another entry for km reimbursed at a rate of the difference between our rate of reimbursement and the ATO rate of reimbursement ($0.08). This seems very difficult and annoying. Cheers Becky
