Carrying Costs & Kilometres: Updates to Vehicle-Based Deductions in 2026

Calculating vehicle expense deductions just got cheaper: the cents-per-kilometre rate rises to 91¢ from 1 July 2026. If you use your car for work, here’s what that means—and whether you should switch deduction methods.

Why the Change Matters

If you're claiming car expenses using the cents-per-kilometre method, your rate has increased from 89¢ to 91¢ per kilometre for the 2026-27 income year. This is a modest increase, but over numerous trips it adds up, especially for remote or mobile workers. (softwaredevelopers.ato.gov.au)

Two Methods: Which One Works Best

MethodWhat it coversWhen it’s worthwhile
Cents-per-kilometreFixed rate per business kilometre up to a capped limit—no need for receipts.Best if you travel modest distances and car expenses (fuel, maintenance, depreciation) are small relative to earnings.
Logbook methodActual costs proportioned to business use—needs detailed record-keeping.Superior when business usage is high or expenses are substantial.

Actionable Tips

  • If you primarily use the cents method, update your payroll or tax software to use the 91¢ rate.
  • Keep good records of odometer readings and trips—limit still applies.
  • If you occasionally use your car for work, compare your actual costs vs cents method to see which gives greater deduction.
  • For contractors, mobile workers, or gig economy participants, it may be more beneficial to maintain a logbook if travel is frequent.

Example Comparison

Suppose you drive 10,000 business kilometres in a year.

  • At 89¢/km, that equals $8,900 deduction.
  • At 91¢/km, it becomes $9,100 — an extra $200.

If your total car expenses (fuel, wear and tear, insurance) are $12,000 for business use, and your business percentage is 80%, logbook method gives $9,600 deduction. In that case, logbook still wins.

Things to Watch Out For

  • The cents-per-kilometre method is capped (for example, 5,000 business km commonly) so for high-mileage users it may not apply.
  • Must elect to use the cents method and meet eligibility requirements.
  • If changing methods, documentation helps in case of audit.

Conclusion

While not a high-stakes reform, the updated rate is a useful reminder to review how you claim vehicle deductions. For some taxpayers, switching to the logbook method or revisiting travel usage could yield better tax outcomes.
