Steps to calculate your fuel tax credits
There are three steps to calculate your fuel tax credits:
Work out the eligible quantity
Work out how much fuel (liquid or gaseous, measured in litres or kilograms) you acquired for each business activity, and how much is eligible for fuel tax credits.
Exclude any fuel:
- used in an ineligible activity – for example, in vehicles of 4.5 tonnes GVM or less travelling on public roads
- if the fuel tax credits have already been claimed earlier in the supply chain – for example, claimed by the packager)
- used for private purposes
- you acquired, but didn't use because it was lost, stolen or otherwise disposed of.
To work out the quantity of fuel when claiming fuel tax credits, you can use any apportionment method considered fair and reasonable for your circumstances.
Common methods to work out the eligible quantity of fuel are:
Standard conversion rates for gaseous fuels are:
- 1 kg of LPG = 1.885 litres of LPG
- 1 megajoule of CNG = 0.01893 kg of CNG.
Check which rate applies for the fuel
When calculating your fuel tax credits, including fuel used in heavy vehicles, you need to use the rate that applied when you:
- acquired the fuel
- imported the fuel
- entered the fuel for home consumption (into the Australian domestic market) if you manufactured the fuel.
Work out the amount
Work out the amount of your fuel tax credits in dollars.
You do this by multiplying the eligible quantity of fuel by the relevant fuel tax credit rate when you acquired the fuel (step 1 x step 2). You must divide the result by 100 to convert it into dollars.
When you have worked out the amount for the relevant BAS period, add the dollar amounts, then claim the whole dollar amount by writing it at label 7D on your BAS.
