Car logbook rules and business car tax in Australia
What a car logbook needs to contain
Under the rules recorded for Australia, each trip entry should show:
- Date
- Start odometer
- End odometer
- Kilometres
- Business reason
The logbook period is at least 84 days. The business percentage from that period can then be used for 5 years. Keep your records for 5 years.
- The 12 weeks must be continuous and represent your normal driving.
- Record the odometer at the start and end of the logbook period and of each income year you rely on it.
Ways to claim and current rates
Cents per kilometre
A set rate per business km, covering all car costs. Up to 5,000 business km per car per year; no logbook needed, but you must be able to show how you worked out your km.
Capped at 5,000 km a year.
| Vehicle | Rate | Status | Applies |
|---|---|---|---|
| All vehicles | $0.910/km | Confirmed | 2026-07-01 – 2027-06-30 |
Logbook method
Claim the business-use % of actual car costs (fuel, servicing, insurance, rego, interest, depreciation). The % comes from a 12-week logbook, valid for 5 years.
A completed logbook is needed for this method.
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:
- Cents per kilometre$4,550.00
- Logbook method (60% of $8,000)$4,800.00
These are estimates only. A real claim depends on your situation and on conditions this example does not check.
Fuel schemes
Fuel tax credits
Business fuel used off public roads (farm machinery, pumps, generators, a ute driven only on the farm) earns the full credit; heavy vehicles over 4.5 t GVM on public roads earn a lower rate net of the road user charge. Light vehicles on public roads and private use earn nothing.
Who: Businesses registered for GST and for fuel tax credits. · Claimed: Business Activity Statement (BAS) (quarter) Confirmed
Other driving-related savings
Tolls on business trips Confirmed
Tolls on work trips can be claimed separately from the cents per km or logbook method. Tolls between home and your regular workplace can’t.
Parking on business trips Confirmed
Parking fees for business trips can be claimed separately from your car expense method (not at your regular workplace).
Electric cars: home charging rate and FBT exemption Confirmed
With the logbook method, home charging of a zero-emission car can be costed at the ATO’s EV home charging rate (PCG 2024/2: 4.20c per km; the ATO rates page lists a revised 5.47c per km for the FBT year from 1 April 2026, so check which applies to your income year) instead of separate electricity records; it doesn’t apply with cents per km, which already covers running costs. Employer-provided zero-emission cars under the luxury car tax threshold are FBT-exempt; plug-in hybrids lost the exemption from 1 April 2025 unless already committed to.
Home to work travel Confirmed
Normal trips between home and your regular workplace are private in Australia and can’t be claimed.
