The Silver Lining of Record Fuel Prices
In May 2026, filling up your tank feels like a major financial blow. With global tensions pushing prices above $2.40/L, every trip to the bowser hurts.
But there is a silver lining: the ATO has responded by increasing the Cents per KM rate to 88 cents. This is designed to compensate for the very inflation you are experiencing. If you aren't claiming every single business kilometer, you are essentially "donating" your hard-earned cash back to the government.
"I Lost My Fuel Receipts—Can I Still Claim?"
Yes. If you use the Cents Per KM method, you do NOT need fuel receipts.
Under this method, you can claim up to 5,000km per vehicle. All you need is a record of your business trips (a diary or an app). At the new 88c rate, a full 5,000km claim puts a $4,400 deduction on your return. For most sole traders, that's a tax saving of roughly $1,400 to $1,800.
Logbook: The Secret to $10,000+ Claims
If you drive more than 5,000km for work, or if your vehicle is expensive to run (like a 4WD or a van), the Logbook Method is almost always better—especially when fuel prices are high.
Why high fuel prices favor the Logbook:
The Logbook method allows you to claim the actual percentage of all running costs. If fuel prices go up by 30%, your deduction goes up by 30%. The Cents-per-km rate is fixed, but the Logbook is dynamic.
The 2026 Fuel Excise Trap
The temporary halving of the fuel excise in April 2026 provided some relief, but it’s a double-edged sword. Many sole traders think they don't need to track as carefully because "prices are down slightly."
Don't be fooled. Global "risk premiums" are keeping the base price high. Even with the excise cut, you are likely paying more for fuel than you were two years ago. Every kilometer counts.
