Fuel Tax Credit Calculator
Estimate your eligible business fuel tax refunds based on total liters consumed and current government claim rates.
Calculator Overview
Variables Considered
- • Eligible Fuel: The volume of liquid fuel (diesel, petrol) acquired for legitimate, off-road, or heavy transport business operations.
- • Claim Rate: The specific government-mandated rate (in cents) applicable to your industry and vehicle class at the time of purchase.
The Mathematics
The calculation simply converts your cents-per-liter rate into dollars and multiplies it by your total usage:
Refund = Liters × (Rate ÷ 100)
Understanding Fuel Tax Credits
Fuel tax credits are a vital financial relief mechanism for businesses that rely heavily on machinery and transport. Because standard fuel prices include an excise tax designed to fund public road maintenance, businesses using fuel off-road or in heavy vehicles are entitled to claim that tax back.
local_shipping Heavy Vehicles vs. Light Vehicles
Heavy vehicles (over 4.5 tonnes) traveling on public roads receive a partial credit, as the government subtracts a "Road User Charge" from the standard tax rate. Light vehicles (under 4.5 tonnes) are completely ineligible for public road usage claims, but can claim the full rate if the fuel is used off-road on private property.
agriculture Off-Road & Machinery Usage
Fuel used in non-traveling machinery (like generators, excavators, or agricultural tractors) is generally eligible for the maximum fuel tax credit rate, as these machines cause zero wear and tear to public road infrastructure.
update Rate Fluctuations
Always double-check your local tax authority (like the ATO in Australia) for the current rates. Rates adjust multiple times a year based on inflation. You must apply the specific rate that was active on the exact date you acquired the fuel.

Frequently Asked Questions
What are Fuel Tax Credits (FTC)?
Fuel tax credits provide businesses with a credit for the fuel tax (excise or customs duty) included in the price of fuel used in machinery, plant, equipment, heavy vehicles, and light vehicles traveling off public roads or on private roads.
How is the Fuel Tax Credit calculated?
The calculation is straightforward: you multiply your total eligible fuel (in liters) by the specific FTC rate (in cents per liter) that applies to your business activity, and then divide by 100 to get the dollar amount.
What is the Road User Charge (RUC)?
For heavy vehicles (over 4.5 tonnes) traveling on public roads, the government applies a Road User Charge. Your FTC rate for these vehicles is the standard fuel tax excise minus the RUC. Our calculator allows you to input your exact net claim rate directly.
Does the FTC rate change?
Yes. Fuel tax credit rates change regularly (often in February and August) in line with the consumer price index (CPI) and changes to the Road User Charge. Always ensure you are using the correct rate for the exact date the fuel was acquired.
Can I claim fuel used in light vehicles?
You can only claim fuel tax credits for light vehicles (under 4.5 tonnes) if they are traveling off public roads (e.g., on private property, farms, or construction sites). Fuel used by light vehicles on public roads is generally not eligible.
