ATO Cents Per Kilometre Car Expenses Calculator and Logbook

Cents Per Km is one of the methods you can choose to satisfy the substantiation rules for claiming car expenses as a tax deduction.

The ATO’s per kilometre car expense claim rate for the 2025-26 and 2024-25 year is 88 cents per km.

Rates for earlier years are set out below.

How To Claim Using The ATO Cents Per Kilometre Method

For up to 5,000 business kms, this claim method avoids the need to keep track of individual car expenses and receipts. A diary is recommended to keep track of the business kms.

Under this method, full substantiation (e.g. receipts for expenses) isn’t needed, however there must exist an objectively reasonable basis of facts to enable a claim.

The claim allowed is for “Business kilometres“. Business kilometres are those travelled by car in the course of producing assessable income, or between work places. The claim method can be used by the self-employed or employees.

The cents per km claim is based on a per kilometre allowance for up to 5,000 business kilometres a year in total.

If more than 5,000 business kms is established, this claim method can still be used, but the excess over 5,000 kms is ignored.

Choosing The Per Km Set Rate Car Claim Method

Substantiation documents are not formally required for per km car claims. A claim for business kms using a per kilometre rate is a simple alternative to calculating a claim for actual expenses, and covers all running expenses and depreciation.

The simplicity of the claim and minimal record keeping are the main advantages.

However, this claim method only applies up to a maximum of 5,000 business kilometers. If business kms total more than 5,000, a claim can still be made, but is limited to the first 5,000 kms.

The claim method is set out in subsection 28-25(1) of the Income Tax Assessment Act 1997.

Although this claim method avoids the need to keep receipts, the Tax Office still requires some evidence supporting the reason for the claim.

A diary record would meet this objective, but certain other circumstantial evidence may suffice. If in doubt, talk to your accountant.

Once the claim method is chosen for any year, it is not locked in for later years. Taxpayers can choose from year to year which car expense claim method to use.

There is no balancing adjustment on the disposal of a car which has only been claimed on a per km basis.

Log Book Alternative

Ideally a full log book record provides the best decision basis, even though that is not required in the case of the per km method.

This is because a properly maintained log book together with a record of actual expenses enables you to compare the claim value with alternatives, and choose another method if it results in a bigger claim.

Per kilometre – multiple claimants, multiple cars, joint owners

More than one car can be included in a claim for a financial year, and more than one person can conceivably make a claim in respect of the same vehicle used at different times.

For a useful explanation of joint and same-car claims, as well as some great log book and diary tips, see Bantacs Accountants “Claiming a motor vehicle” (PDF)

The per kilometre claim method doesn’t prescribe specific record-keeping requirements, but the claim has to be ‘reasonable’, and you need to be able to show some logical basis for the kilometres figure derived.

Motor vehicle cents per kilometre rates – 2015-16

Per Km rate for 2015-16 is 66 cents per km, which also applies for 2016-17 and 2017-18 (up to 5,000 km) regardless of engine size.

From 1 July 2015 a single flat rate per business kilometre is used for the cents/km claim method – regardless of engine size. The amending legislation is here.

The rates set in future years are intended to more closely reflect the actual operating cost of cars.

The claim is made out by first selecting the applicable Rate per Km, and then multiplying that by the number of kilometres (up to 5,000):

$Claim = Rate (cents) x Kms
