What Is a Fuel Tax Credit Calculator?
A Fuel Tax Credit Calculator helps Australian businesses quickly estimate how much they can claim back from the Australian Taxation Office (ATO) for the fuel tax (excise or customs duty) included in the price of fuel used in their business operations. Instead of manually working through ATO rate tables, this calculator gives you an instant estimate based on your fuel type, quantity, and how the fuel was used.
What Are Fuel Tax Credits?
Fuel Tax Credits are a Australian Government initiative that allows eligible businesses to claim a credit for the fuel tax embedded in the price of fuel used for business purposes. The scheme exists because fuel tax is primarily designed for on-road use — businesses that use fuel off-road or in certain machinery shouldn't bear that cost.
Fuel tax credits are claimed through your Business Activity Statement (BAS) and can represent significant savings for fuel-heavy industries.
Who Is Eligible to Claim Fuel Tax Credits?
Your business may be eligible if you are registered for GST and use fuel in any of the following ways:
- Off-road business activities — mining, agriculture, construction, and forestry
- On-road use in heavy vehicles — vehicles with a Gross Vehicle Mass (GVM) over 4.5 tonnes travelling on public roads
- Machinery and equipment — forklifts, generators, pumps, and other plant equipment
- Marine vessels used for business purposes
- Rail transport operations
- Light vehicles travelling off public roads on private property
Who Cannot Claim Fuel Tax Credits?
Not all fuel use qualifies. You cannot claim for:
- Fuel used in light vehicles (under 4.5 tonnes GVM) travelling on public roads
- Aviation fuel in most circumstances
- Fuel used for private or domestic purposes
- Fuel purchased by non-GST registered businesses
- Activities where a grant or subsidy has already been received for the fuel cost
Current Fuel Tax Credit Rates
The ATO adjusts fuel tax credit rates twice a year — in February and August — in line with the Consumer Price Index (CPI). Rates differ based on fuel type and how it is used:
| Fuel TypeOff-Road / Machinery UseOn-Road Heavy Vehicle | ||
| Diesel | Higher rate applies | Lower rate applies |
| Petrol | Higher rate applies | Not claimable |
| Liquefied Petroleum Gas (LPG) | Eligible | Eligible |
| Liquefied Natural Gas (LNG) | Eligible | Eligible |
| Compressed Natural Gas (CNG) | Eligible | Eligible |
| Biodiesel | Eligible | Eligible |
Always check the ATO website for the most current rates before lodging your BAS, as rates change biannually.

Industries That Benefit Most From Fuel Tax Credits
Fuel tax credits can deliver substantial savings for fuel-intensive industries, including:
- Agriculture and farming — tractors, harvesters, irrigation pumps
- Mining and resources — heavy earthmoving equipment, generators
- Construction — excavators, cranes, compactors, site vehicles
- Transport and logistics — heavy vehicles over 4.5 tonnes GVM
- Forestry — logging machinery and off-road equipment
- Marine industries — commercial fishing and freight vessels
How to Claim Fuel Tax Credits
Claiming is straightforward once you have the right records in place:
- Keep fuel records — invoices, receipts, and fuel logs for every eligible purchase
- Separate eligible from non-eligible use — especially important if vehicles are used both on and off-road
- Calculate your entitlement using current ATO rates
- Report the amount in Label 7D of your Business Activity Statement (BAS)
- Lodge your BAS on time — credits are paid as part of your BAS refund or offset against other tax liabilities
Record Keeping Requirements
The ATO requires businesses to maintain adequate records to support fuel tax credit claims, including:
- Tax invoices for all fuel purchases
- Fuel usage logs showing how and where fuel was used
- Vehicle or equipment records including GVM for road vehicles
- Records must generally be kept for a minimum of 5 years
Poor record keeping is the most common reason the ATO disallows fuel tax credit claims during audits.
Frequently Asked Questions
Can sole traders and small businesses claim fuel tax credits? Yes, as long as you are registered for GST and use fuel for eligible business activities. There is no minimum business size requirement.
How often can I claim fuel tax credits? You claim through your BAS — this could be monthly, quarterly, or annually depending on your reporting cycle.
What happens if I claim the wrong amount? You can correct errors on a future BAS. However, significant errors or deliberate overclaiming can attract ATO penalties, so accuracy is important.
Can I claim fuel tax credits for a vehicle used for both business and personal use? Only the business-use portion is eligible. You must keep records that clearly separate business from private use.
Are fuel tax credit rates the same across all Australian states? Yes. Fuel tax credits are a federal scheme administered by the ATO and apply uniformly across all states and territories.
What if I missed claiming fuel tax credits in a previous BAS period? You can generally amend a previous BAS to include missed fuel tax credits, subject to a 4-year time limit from the original lodgement date.
Fuel tax credit rates change biannually. Always verify current rates at ato.gov.au before lodging your claim. This calculator is for estimation purposes only and does not constitute tax advice.
