Using the cents per kilometre method
The ‘cents per kilometre’ method broadly allows an individual taxpayer to claim up to a maximum of 5,000 business kilometres per car, per year without the need to keep any written evidence (e.g. receipts) of car expenses.
Importantly, taxpayers making a ‘cents per kilometre’ claim are required to demonstrate that they worked out the number of business kilometres they claimed on a reasonable basis.
Taxpayers claiming under this method will generally fall into one of two categories, being either those who undertake a regular or irregular pattern of work-related travel.
If a taxpayer has a regular pattern of work-related travel (e.g. a 60 kilometre round trip to the warehouse to pick up supplies twice a week, 40 weeks in the year), then this type of explanation would generally be sufficient to justify the claim.
However, if the taxpayer has an irregular pattern of work-related travel, then they would need to make a note (e.g. in a diary) of each trip.
Also, remember that, for the 2019 income year, the rate that is applied (up to the 5,000 business kilometre maximum) is 68 cents (up from 66 cents in 2018) per business kilometre travelled.
