Car logbook rules and business car tax in New Zealand

This is general information, not tax advice. Every money figure is an estimate. Please check your claim with the tax authority in New Zealand or a registered tax adviser. Updated 2026-11-10. The rules were last checked on 2026-11-09.

What a car logbook needs to contain

Under the rules recorded for New Zealand, each trip entry should show:

  1. Date
  2. Start odometer
  3. End odometer
  4. Kilometres
  5. Reason for the business journey

The logbook period is at least 90 days. The business percentage from that period can then be used for 3 years. Keep your records for 7 years.

  • Logbook: start date and odometer, then date, distance and reason for each business journey, then end date and odometer (IRD).
  • A logbook calculation can be used for up to 3 years if business use stays within 20% of the logbook figure; after that keep a new 90-day logbook (IRD use-a-logbook page, checked 9 Nov 2026).
  • Keep records 7 years (IRD record keeping guidance via search; the page itself was not fetched).
  • You must keep using the same method for as long as you own the vehicle.

Ways to claim and current rates

Kilometre rates

Business km × IRD kilometre rate. Tier 1 covers fixed and running costs; Tier 2 (running costs only) applies once the vehicle’s total travel, business and private, passes 14,000 km in the income year. Rates include depreciation. Published after each 31 March year end.

No rate has been published for this year yet.

Logbook (actual costs)

Business-use % from a logbook kept for at least 90 consecutive days × actual running costs, plus depreciation on the business share.

A completed logbook is needed for this method.

25% without a logbook

Without a logbook you can claim 25% of running costs; Inland Revenue may ask you to back up the percentage.

You deduct 25% of your car costs.

Worked example (estimate)

Say you drove 5,000 km for work in a year, your car costs came to $8,000 and your logbook shows 60% business use. With the figures on this page the estimates are:

  • Kilometre rates (Petrol)no rate for this year yet
  • Logbook (actual costs) (60% of $8,000)$4,800.00
  • 25% without a logbook (25% of $8,000)$2,000.00

These are estimates only. A real claim depends on your situation and on conditions this example does not check.
