  • Powering auxiliary equipment

    You can claim fuel tax credits for liquid fuels and gaseous fuels you use to power auxiliary equipment in your heavy vehicles. These are equipment and mechanisms unrelated to a vehicle’s travel along public roads, for example:

    • the mixing barrel of a concrete truck
    • garbage bin lifters and compacting mechanisms of a garbage truck
    • the refrigeration unit of a vehicle that transports temperature-sensitive goods
    • air-conditioning of a commercial bus or coach for passenger comfort
    • elevated work platforms

    The fuel used to power the auxiliary equipment may be sourced from a separate fuel tank or from the tank that fuels the main engine. The auxiliary equipment may also take its power from the main engine (known as 'power take-off'), which in turn increases the fuel used.

    The fuel tax credit rate for this activity is not reduced by the road user charge – including when the fuel is used in a heavy vehicle travelling on public roads.

    Amending earlier claims for auxiliary equipment

    You can amend your earlier fuel tax credit claims for fuel used to power the auxiliary equipment of heavy vehicles travelling on public roads, if all of the following apply:

    • you claimed for liquid fuels using the rate 'in a heavy vehicle for travelling on public roads' that was reduced by the road user charge, or you didn't claim for gaseous fuels because the road user charge reduced your entitlement to nil
    • the amendment is within the time limit – four years from the day after you were required to lodge the BAS for the tax period in which the fuel was acquired.

    You can only claim fuel tax credits for gaseous fuels acquired after 1 December 2011.

    To work out the quantity of fuel used to power the auxiliary equipment for each BAS period, you can use any apportionment method considered fair and reasonable for your circumstances.

    Amending claims for liquid fuels

    Follow the steps below to amend a claim for liquid fuels:

    • Step 1: Work out the quantity of fuel used to power the auxiliary equipment of the heavy vehicle travelling on public roads for each BAS period.
    • Step 2: Multiply the quantity of fuel (from Step 1) by the fuel tax credit rate 'To power auxiliary equipment of a heavy vehicle travelling on public roads' for that period.
    • Step 3: Multiply the same quantity of fuel (from Step 1) by the fuel tax credit rate you originally used when calculating your fuel tax credits for each BAS period (rate reduced by the road user charge).
    • Step 4: Work out the amount of your amendment for each BAS period as follows: Step 2 minus Step 3.
    • Step 5: Add the amounts from each BAS period (from Step 4) to get the total amount of your amendment. Include your amendment at label 7D on your BAS.

    Example: Step 4: Work out amendment amount for a BAS period

    Paul's transport business supplies goods to various stores in 12-tonne trucks with refrigerated trailers.

    On 10 July 2015, Paul purchased 10,000 litres of diesel for use in his trucks. When he originally worked out his fuel tax credits he used the rate 12.76 cents per litre for the entire amount of fuel. This rate is reduced by the road user charge.

    Paul worked out 10% of that fuel was used to power the refrigeration unit. He can submit an amendment to claim back the road user charge on 10% of the fuel used in his trucks – 1,000 litres.

    Paul refers to the rates table and works out the amount of his amendment as follows:

    Step 1: 1,000 L × $0.389 = $389.00 (this is the amount he should have claimed)

    Step 2: 1,000 L × $0.1276 = $127.60 (this is the amount he has already claimed)

    Step 3: $389.00 − $127.60 = $261.40 (this is the additional amount he can claim)

    Paul can amend his BAS for the quarter ended September 2016 (his current BAS) by including $261 at label 7D.

    End of example

    Claiming for gaseous fuels

    Follow the steps below to claim for gaseous fuels:

    • Step 1: Multiply the fuel tax credit rate that applied by the quantity of fuel used to power the auxiliary equipment for each BAS period.
    • Step 2: If you're claiming for multiple BAS periods, add the amounts from each BAS period together to get the total amount of your claim. Include this amount at label 7D on your BAS.
