Pool Cars — When BIK Does Not Apply

A pool car is exempt from BIK tax. To qualify as a genuine pool car, the vehicle must:

  • Be available to and actually used by more than one employee
  • Not normally be kept overnight at an employee’s home
  • Not be used by any one employee to a greater extent for private journeys than for business journeys
  • Private use must be merely incidental to the business use

If HMRC investigates and determines a vehicle does not meet these tests, the full BIK charge applies. Pool car status requires proper records — vehicle log books showing who used the car and for what purpose.
