The personal driving of an employer's vehicle is a taxable benefit to the employee.
Personal driving is any driving by an employee, or a person related to the employee, for purposes not related to his or her employment.
This includes:
We do not consider it to be personal driving if you need or allow the employee to travel directly from home to a point of call (such as a salesperson visiting customers) other than your place of business to which the employee regularly reports, or to return home from that point.
