Employee Vehicle Reimbursements
If you are paying your employees a motor vehicle allowance as a part of their salary package this is taxed as a part of their wages. A better way would be for the employee to submit their actual expenses for reimbursement or submit a mileage claim. Both of these are non-assessable in the hands of the employee and are claimable as a tax deduction for the business, therefore removing the need for the employee to be taxed on these amounts.
Alternatively you could reimburse them for mileage – the current rate is $0.73c per kilometer for the 2017 income tax year.
