Use the rates listed below to calculate the allowable expense for using your vehicle for business purposes for the 2017/2018 income year.

For the first 14,000 kilometres, this rate is 76 cents per kilometre for petrol, diesel, hybrid, or electric vehicles. For each kilometre over 14,000 kilometres, the rate is lower and depends on the vehicle type.

The calculation is: kilometre rate x kilometres travelled x business proportion

Where:

  • 'kilometre rate' is one of the rates in the table below
  • 'kilometres travelled' is the total number of kilometres travelled for business and personal purposes
  • 'business proportion' is your logbook calculation of the how much your vehicle is used for business purposes. This is written as a decimal (so if 25% of your vehicle’s use is for business, the business proportion is 0.25).
Vehicle type First 14,000 km After 14,000 km
Petrol or diesel 76 cents 26 cents
Petrol hybrid 76 cents 18 cents
Electric 76 cents 9 cents
