The rate covers all your car's running costs, including fuel, registration, insurance, servicing and depreciation, so you can't claim those as well. General information, not tax advice.

How it's worked out

Claim = work or business km (up to 5,000 per car) × the rate for that year

The rate is 88c a km for 2025–26 and 91c a km for 2026–27. For example, 3,200 km in 2025–26 is 3,200 × $0.88 = $2,816.

Common questions

Which rate do I use?
Use the rate for the year the trips were in. Trips from 1 July 2025 to 30 June 2026 use 88c. Trips from 1 July 2026 use 91c.
What records do I need?
You don't need receipts, but you need to be able to show how you worked out your km, for example a diary of your regular work trips.
I drove more than 5,000 km. Can I claim more?
Not with this method: it stops at 5,000 km per car. With the logbook method, you keep a logbook for 12 weeks and claim the business-use percentage of your actual car costs.
Which trips count?
Trips for work or business, such as between job sites, to see clients or to pick up supplies. Normal trips between home and your regular workplace usually don't.
