ATO cents per km rates
The cents per kilometre method lets you claim a set rate for each business kilometre you drive in your own car. The rate covers fuel, servicing, registration, insurance and depreciation, so you do not add those on top. The ATO sets the rate each year.
| Income year | Rate per km | Most you can claim (5,000 km) |
|---|---|---|
| 2026-27 | 91 cents | $4,550.00 |
| 2025-26 | 88 cents | $4,400.00 |
| 2024-25 | 88 cents | $4,400.00 |
| 2023-24 | 85 cents | $4,250.00 |
| 2022-23 | 78 cents | $3,900.00 |
How the cents per km method works
Take your business kilometres for the year, up to 5,000 per car, and multiply by the rate. If you drove 3,000 business kilometres in 2026-27, your deduction is 3,000 x $0.91 = $2,730.
You do not need receipts for the running costs. You do need to be able to show how you worked out your kilometres, for example a diary, a list of trips with dates and client names, or the myDeductions tool in the ATO app. A reasonable estimate is allowed: 20 km a week for 48 weeks is 960 km. You also need to be able to show that you own or lease the car.
The method is for sole traders and partnerships (where at least one partner is an individual), and only for cars: vehicles that carry less than one tonne and fewer than 9 passengers. Companies and trusts use the actual cost method, and so does anyone claiming for a motorcycle, a ute or van that carries a tonne or more, or a minivan. Parking and tolls are not car expenses, so they are not covered by the rate.
Travel between home and your usual place of work is private, so it does not count. If you run your business from home, a trip from home for business, such as to a client, does count. Trips between jobs, to clients and to buy supplies usually do.
Cents per km or logbook method?
Cents per km is quick and needs no cost receipts, but it stops at 5,000 km. The logbook method has no kilometre limit. You keep a logbook for 12 weeks, work out your business use percentage, then claim that share of fuel, rego, insurance, servicing and depreciation. If you do a lot of driving for work, it often gives the bigger deduction.
