The rates and the 5,000 km limit come from the ATO's cents per kilometre method page (last updated 12 August 2026). This follows that page, which is written for individuals. Always check the ATO page for the latest figures.
The ATO lists 91 cents per kilometre for 2026-27, 88 cents for 2024-25 and 2025-26, 85 cents for 2023-24, 78 cents for 2022-23 and 72 cents for 2020-21 and 2021-22 (ATO page last updated 12 August 2026).
The ATO says you can claim a maximum of 5,000 work-related kilometres per car per year. At the 2026-27 rate of 91 cents that is up to $4,550.
No. The ATO says the rate covers all your car expenses, including decline in value, registration and insurance, maintenance, repairs and fuel, and that you cannot add these or any other car expenses on top of the rate.
You do not need receipts for car expenses under this method. The ATO says you do need a record that shows how you worked out your work-related kilometres, for example a diary or the myDeductions tool in the ATO app, and you need to be able to show that you own the car.
No. It is an estimate using the ATO's published rate and limit. The rules differ depending on your situation, for example whether you are an employee, a sole trader or a company, so check the ATO's guidance or ask a registered tax agent.
