  • Heavy vehicles

    Heavy vehicles, including heavy emergency vehicles, are vehicles that have a gross vehicles mass (GVM) greater than 4.5 tonnes – diesel vehicles acquired before 1 July 2006 can equal 4.5 tonnes GVM.

    The GVM of a vehicle is the GVM accepted by the authority that registered the vehicle. Trailers cannot be included in the GVM of a rigid vehicle. For prime movers, the GVM is the gross combination mass – the mass of the vehicle and the trailer.

    You can claim fuel tax credits for eligible fuels you use in your business in heavy vehicles:

    If you use a heavy diesel vehicle manufactured before 1 January 1996 for travelling on public roads, you will need to meet an environmental criterion before you can claim fuel tax credits.

    Eligible fuels include taxable fuels such as liquid fuels (for example, diesel, petrol or fuel blends) and gaseous fuels – liquefied petroleum gas (LPG), liquefied natural gas (LNG) and compressed natural gas (CNG).

    Further guidance for calculating fuel tax credits

    We have released further guidance for calculating fuel tax credits for heavy vehicles.

    • Apportionment methods for auxiliary equipment
      • PCG 2016/11 – which replaces PSLA 2013/4(GA) – is a guide to the methods used to apportion fuel used in heavy vehicles to power auxiliary equipment, including bin-lifting equipment of a rubbish collection truck. See table 1 for percentages you can use instead of needing to do complex calculations or sample testing.

      • FTD 2016/1 outlines that the fuel tax credit rate will be reduced by the road user charge for fuel that is used in a heavy vehicle for
        • idling on a public road
        • powering the air conditioning unit of a main cabin when travelling on a public road.
    • Public roads
      • The explanation of 'public roads' in FTR 2008/1 has been clarified.
      • A public road is a road that is available for use by members of the public, and includes toll roads, bus lanes and busways. The fuel used in a 'heavy vehicle for travelling on public roads rate should be used when calculating your fuel tax credits for fuel used when travelling on these roads.
      • Forestry, mining access and agricultural property roads are examples of roads that are not considered ‘public’. Fuel tax credits should be claimed for fuel used when travelling on these roads using the ‘all other business uses’ rate.
