Are you being reimbursed by your company through a fixed or variable vehicle allowance?
- Yes – Your vehicle allowance is a taxable benefit. You must keep a mileage log to claim back any taxes you are paying on your car allowance.

The vehicle is owned or leased by my company.
Is the vehicle used for personal purposes outside business hours?
