How the estimate works

01

Add total travel

Enter every kilometre travelled by the vehicle in the income year, including private use.

02

Add business travel

We use this to work out the business-use percentage applied to each tier.

03

Apply IRD rates

The first 14,000 total kilometres use Tier 1; kilometres above that use Tier 2.

PLEASE NOTE

Before you rely on the result

  • The kilometre rates cover cars, vans and tray-back vehicles such as utes. They do not apply to motorcycles or scooters.
  • Travel between home and your usual workplace is generally private travel.
  • IRD rates are a reasonable-estimate method. Your employer may use another reasonable method for employee reimbursements.
  • This calculator is general information, not tax advice. Check your records and circumstances before making a claim or payment.
