I work for a small company. Less than 25 employees. Three employees have a company vehicle. The owner, the GM, and office manager/HR. What kind of personal tax implications are there for these vehicles? They rarely make sales calls. At most two per year. The few trips to the hardware store and when an employee is called for a random drug test the office manager will take the employee to get tested. Do the three people that have these cars pay a per mileage tax for personal use of the vehicle?
