Home–Work Trips: A Note Before You Log

Ordinary commuting between home and a regular workplace generally isn't deductible — the ATO carves out an exception for genuine emergency or on-call work outside normal rostered hours, which is what the callout log below is built for.

This is general information, not tax advice. Keep a brief reason for each callout (already prompted below) as your supporting evidence, and confirm the deductibility of these specific trips with a registered tax agent or accountant — particularly if any callouts happen during normal rostered hours rather than genuinely after-hours emergencies.

Log an On-Call / After-Hours Callout

Home ↔ Work, using the fixed distance set above.

Log a Client / Site Visit

Work ↔ client or patient address, entered fresh each time since the destination varies.

Doing several visits in a row without returning to base between each? Log each leg separately as a one-way trip instead of using round trip.

Backup & Export

Everything is saved automatically in this browser. Export regularly so records survive a browser reset, or hand a copy to your accountant.

How the ATO Cents-Per-Kilometre Method Works

A quick reference for anyone new to claiming work-related car expenses.

One flat rate covers everything

The cents-per-km rate is all-inclusive — fuel, rego, insurance, servicing, and depreciation are all bundled into that single per-kilometre figure. You can't claim any of these separately if you use this method; it's one or the other.

Capped at 5,000 km per car, per year

You can claim a maximum of 5,000 business kilometres per car under this method each financial year. If your genuine business travel goes higher than that regularly, the logbook method (which has no cap, but requires a 12-week logbook and tracking actual expenses) may claim more overall — worth comparing with your accountant if you're consistently over the cap.

No receipts needed, but you still need records

This method doesn't require fuel or maintenance receipts, but the ATO does expect you to show how you worked out your business kilometres — a diary, calendar, or a log like this one showing dates, routes, and reasons for each trip.

Ordinary commuting usually doesn't count

Driving from home to your regular workplace and back is treated as private travel, not business travel, even if you're a professional who works odd hours. The recognised exception is genuine emergency or on-call travel outside your normal rostered hours — which is exactly what the callout log on this page is designed to capture separately from routine site or client visits.

Frequently Asked Questions

Not tax advice: This tool applies the current ATO cents-per-kilometre rate and cap to the trips you log, but doesn't assess whether any specific trip is genuinely deductible for your circumstances. Always confirm your car expense claim, and particularly the deductibility of home-to-work travel, with a registered tax agent or accountant.
