Cents per kilometre method

Check how sole traders and some partnerships can use the cents per kilometre method for car-related business expenses.

Last updated 29 June 2023

This method

Only use this method if you are a sole trader or partnership (where at least one partner is an individual) claiming for a car.

The cents per kilometre method:

  • uses a set rate for each kilometre travelled for business
  • allows you to claim a maximum of 5,000 business kilometres per car, per year
  • doesn't require written evidence to show exactly how many kilometres you travelled (but we may ask you to show how you worked out your business kilometres, for example diary records)
  • uses a rate that takes all your vehicle running expenses (including registration, fuel, servicing and insurance) and depreciation into account.


Rates are reviewed regularly. The rate is:

  • 85 cents per kilometre for 2023–24
  • 78 cents per kilometre for 2022–23
  • 72 cents per kilometre for 2020–21 and 2021–22
  • 68 cents per kilometre for 2018–19 and 2019–20
  • 66 cents per kilometre for 2017–18.

How you use this method

To work out how much you can claim, multiply the total business kilometres you travelled by the rate.
