How does the cents per kilometre method work?

You can claim $0.88 per business kilometre, up to a maximum of 5,000 km per year. This is the simplest method -- no receipts needed for fuel/expenses. You just need to be able to show how you calculated your business km (e.g. a reasonable estimate based on your work pattern).

How does the logbook method work?

You keep a logbook for a continuous 12-week period to determine your business-use percentage. You then apply this percentage to all your actual car expenses (fuel, insurance, registration, servicing, depreciation, interest on car loan). The logbook is valid for 5 years unless your circumstances change significantly.

Which method is better?

The logbook method is often better for high-kilometre or expensive vehicles with significant business use. The cents-per-km method is simpler and better when your total expenses are low or you drive fewer than 5,000 business km per year.

ATO-Aligned: Cents per km rate of $0.88 is for 2025-26. Commuting from home to your regular workplace is not claimable. Travel between workplaces or to alternative workplaces generally is.
