Van Benefit in Kind — 2027/28

Company vans have a flat-rate BIK charge rather than a percentage of list price:

2027/28
Van BIK flat rate £4,020 (2026/27 rate — 2027/28 to be confirmed)
Fuel benefit (private fuel provided) £769 (2026/27 rate)
Annual tax cost (basic rate, 20%) ~£804
Annual tax cost (higher rate, 40%) ~£1,608
Zero-emission vans 0% BIK

Zero-emission vans (electric) attract 0% BIK — the same principle as electric cars, making them highly tax-efficient for employer and employee.

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.
