1. The Australian Fuel Tax Credit Framework (2026–27)
Fuel Tax Credits (FTC) in Australia are governed by the Fuel Tax Act 2006 and administered by the ATO.
FTCs provide eligible Australian businesses with a dollar-for-dollar refund on the excise embedded in commercial fuel, reducing operating costs for transport, primary production, and construction enterprises.
2. Annual Fuel Volume & ATO Tax Refund Benchmarks
| Annual Fuel Volume | Usage Activity Type | ATO FTC Rate | Annual BAS Refund | Reporting Frequency |
|---|---|---|---|---|
| 10,000 Litres Diesel | Off-Road Machinery (Agriculture/Mining) | 49.6 c / litre (Full Excise) | $4,960.00 BAS Refund | Quarterly BAS Label 7D |
| 25,000 Litres Diesel | On-Road Heavy Vehicles (>4.5t GVM) | 20.8 c / litre (Net of RUC) | $5,200.00 BAS Refund | Quarterly BAS Label 7D |
| 50,000 Litres Diesel | On-Road Heavy Transport Fleet | 20.8 c / litre (Net of RUC) | $10,400.00 BAS Refund | Quarterly BAS Label 7D |
| 100,000 Litres Diesel | Off-Road Civil Construction Equipment | 49.6 c / litre (Full Excise) | $49,600.00 BAS Refund | Quarterly BAS Label 7D |
3. The Mathematics of FTC Rates & Road User Charge (RUC)
Total Fuel Tax Credit Refund (FTC_total) for off-road litres (L_off), on-road heavy litres (L_on), full excise rate (R_excise), and Road User Charge (RUC) is:
Example Calculation (25,000 Litres Diesel On-Road Heavy Truck @ 49.6c Excise, 28.8c RUC):
- Net On-Road Heavy FTC Rate: 49.6c - 28.8c = 20.8 cents / litre.
- Annual BAS Fuel Tax Credit Refund: 25,000 L × $0.208 = $5,200.00 BAS refund.
- If 10,000 L were used Off-Road: 10,000 L × $0.496 = $4,960.00 extra refund!

5. Fuel Tax Credit Mistakes & Checklist
Claiming Fuel Tax Credits for Light Commercial Vehicles On-Road
Claiming FTC for utes or vans under 4.5t GVM driving on public roads, leading to ATO audit clawbacks and interest penalties.

Frequently Asked Questions (FAQ)
What are Fuel Tax Credits (FTC) and who is eligible to claim them in Australia?
Fuel Tax Credits provide Australian businesses with a tax refund for the fuel excise included in the price of fuel used in business activities (machinery, heavy vehicles >4.5t GVM, agriculture, forestry, mining, and off-road power generation).
How does the Road User Charge (RUC) affect Fuel Tax Credit rates for heavy road vehicles?
Fuel used in heavy vehicles (>4.5t GVM) traveling on public roads attracts a Road User Charge (RUC) reduction. The net FTC rate for on-road heavy vehicles is equal to the full fuel excise rate minus the RUC rate.
Can light vehicles (under 4.5t GVM) claim Fuel Tax Credits for public road travel?
NO! Light vehicles under 4.5 tonnes Gross Vehicle Mass (such as standard dual-cab utes, vans, or passenger cars) traveling on public roads are strictly ineligible for Fuel Tax Credits.
Why do ATO Fuel Tax Credit rates change every February and August?
The ATO indexes fuel excise rates twice yearly (February and August) based on the Australian Consumer Price Index (CPI). FTC claim rates must match the exact rate in effect when the fuel was purchased.
How are Fuel Tax Credits claimed on the quarterly Business Activity Statement (BAS)?
FTC claims are entered at Label 7D on your Business Activity Statement (BAS). The calculated refund reduces your net BAS GST payable or increases your cash tax refund from the ATO.
