Are Fuel Costs Tax Deductible for Australian Businesses?

Fuel is a regular expense for many businesses, and with prices still elevated, it's a common question at tax time: Can you claim it?

In most cases, yes — but only to the extent it relates to business use. How you claim it depends on how your vehicle is used and how well you track it.

Start With How the Vehicle Is Used

If a vehicle is owned and used entirely by the business, fuel is generally fully deductible. This often applies to company-owned vehicles used for delivery, transportation or site work.

Where things get more nuanced is when the vehicle is used for both business and personal purposes. In that case, you can only claim the business-use portion of fuel.

The Australian Taxation Office (ATO) outlines two common methods for calculating these expenses:

• Logbook method – tracks actual usage over a representative period
• Cents per kilometre method – applies a set rate per kilometre, up to a limit

The right option depends on how often the vehicle is used for work and how detailed your records are.

Not All Travel Counts

One of the most common mistakes is assuming all driving is deductible.

Fuel used for business-related travel can generally be claimed — for example, travelling between job sites, visiting clients or picking up supplies.

Travel between home and your regular place of work is usually considered private and can't be claimed. This stage is where many claims get adjusted or reduced.

Keep Records as You Go

The strength of your claim comes down to your records.

You don't need anything overly complex, but you do need consistency. Keeping receipts, tracking kilometres and maintaining a logbook (if required) make the process much smoother.

Trying to estimate fuel use at year-end often leads to inaccuracies or missed deductions.

Consider Fuel Tax Credits

Fuel tax credits can sometimes help you recover a portion of your fuel cost. This tends to apply where fuel is used in business activities beyond standard on-road driving — for example, certain equipment or off-road use.

It's not something every business will qualify for, but if fuel is a high cost in your operations, it's worth checking rather than assuming.

Final Thoughts

Fuel is usually deductible, but only where the business use is clear and supported.

Most issues don't come from the rules themselves — they come from how the claim is tracked. Keeping it consistent during the year makes things much easier at tax time.
