ATO Log Book Rules & Car Expense Claims 2026
1. Travel Allowance vs. Work-Related Car Expenses
Understanding this ATO distinction is crucial to claiming correctly.
Travel Allowance: A payment from your employer for expected costs when you travel overnight for work.
Work-Related Car Expenses: Costs you incur using your own car during your normal workday.
The iDrive app is designed to automate work-related car expenses.
2. The Two Methods for Claiming Car Expenses in 2026
Cents per KM
SimpleHow It Works:
Multiply your work-related kilometres by the ATO rate of 88 cents per kilometre.
Best For:
- Low-distance claims
- Simple record-keeping
- No receipts needed
iDrive's Role:
Track & estimate kilometres automatically
Logbook Method
AccurateHow It Works:
Claim the business-use percentage of your total vehicle running costs based on a 12-week logbook.
Best For:
- Higher business use
- Maximising claims
- 5-year validity
iDrive's Role:
Fully ATO-compliant digital logbook
Automatic percentage calculations
Which Method Should You Choose?
Simple rule: If you drive more than 5,000 work kilometres annually or have high vehicle running costs, the Logbook Method will almost always give you a larger claim. For occasional work travel, Cents per KM is simpler.
3. Core ATO Logbook Rules
12-Week Period
Record a continuous 12-week period that represents your typical usage. This logbook remains valid for 5 years unless your usage pattern changes significantly.
Trip Tracking
Accurate recording of every journey's start and end. The ATO requires precise distance measurement for each trip to calculate business use percentage.
Trip Documentation
For each trip, record: date, distance travelled, and purpose/reason for the journey. Personal trips must also be recorded.
iDrive automates all these requirements: Our app tracks trips, calculates distances, and generates ATO-compliant reports with all required details.
