Kilometre Rates

Every year Inland Revenue publishes kilometre rates that customers can use to calculate the business use of motor vehicles. These kilometre rates represent the average cost of operating a motor vehicle based on industry figures. 

The Commissioner has published two operational statements explaining how to use the annual kilometre rates to calculate:

  • the business portion of motor vehicle costs for deductibility; or 
  • the tax-exempt portion of an employee reimbursing payment where the employee uses their private motor vehicle in the employer’s business.
