Fuel tax credits - basic method for heavy vehicles

Your fuel tax credit entitlement is reduced by the amount of the road user charge to the extent that the fuel is used for travel on a public road. [1] This requires an apportionment between the fuel used for travel on a public road and that used for other purposes.

This Guideline provides a simplified apportionment method to assist you in meeting your fuel tax credit obligations.

The use of the simplified method is not mandatory but aims to reduce compliance costs and make it easier for you to calculate fuel tax credits for diesel acquired and used in heavy vehicles.

In this Guideline, a 'heavy vehicle' is one that has a gross vehicle mass of greater than 4.5 tonnes (or, if acquired before 1 July 2006, has a gross vehicle mass of 4.5 tonnes or more). It is only these vehicles that are entitled to any credit for fuel used for travel on a public road.

This Guideline applies to diesel acquired on or after 1 October 2020.

You may rely on this Guideline to calculate your fuel tax credit entitlement for a particular tax period if: • you are registered for goods and services tax • you have an entitlement to a fuel tax credit for diesel (and are not disentitled) [2] • you use diesel in a heavy vehicle for both travelling on public roads and other fuel uses (such as fuel used in the vehicle to power auxiliary equipment and off public roads) • the total fuel tax credit entitlement for the 12 months preceding that particular tax period is $10,000 or less [3] , and • there is a reasonable expectation that your total fuel tax credit entitlement for the current 12-month period (commencing at the beginning of the particular tax period) will be $10,000 or less.

The Commissioner accepts that, due to unforeseen fluctuations or changes in business activity, an entity may in fact exceed the $10,000 entitlement in the current 12-month period. Some discretion and flexibility will be applied to determine whether the circumstances resulting in an excess over $10,000 are consistent with the reasonable expectation described in paragraph 6 of this Guideline.

The method is the basic method for heavy vehicles (BMHV). The method consists of simple formulas to work out the litres of diesel used in vehicles on public roads and the litres of diesel used in vehicles off public roads. The amount of fuel tax credits for the tax period can then be worked out by applying the relevant fuel tax credit rates to these two fuel uses.

To work out the 'litres of diesel used in a vehicle for travelling on public roads', use the following formula: Kilometres travelled on public roads × Diesel consumption rate where: Kilometres travelled on public roads is either: • the actual number of kilometres travelled by the heavy vehicle on public roads in the tax period, or • the derived number of kilometres travelled by the heavy vehicle on public roads in the tax period. You work this out by taking the total kilometres travelled by the heavy vehicle multiplied by 98.4%. [4] Diesel consumption rate is the rate expressed in litres per kilometre from either: • Schedule 1 of this Guideline - accepted diesel consumption rates, or • the vehicle's engine diagnostic reports of 'driving fuel' economy. [5]

To work out the 'litres of diesel used in a vehicle off public roads' (including diesel used to power auxiliary equipment), use the following formula: Total litres of eligible diesel - Litres of diesel used in a vehicle for travelling on public roads where: Total litres of eligible diesel is the total litres of diesel acquired during the tax period for use in a vehicle for which there is an entitlement to a fuel tax credit and no disentitlement [6] . Litres of diesel used in a vehicle for travelling on public roads is the litres worked out using the formula at paragraph 9 of this Guideline.

To work out the 'amount of fuel tax credits for the tax period', use the following formula: Litres of diesel used in a vehicle on public roads × On-road rate + Litres of diesel used in a vehicle off public roads × Off-road rate where: On-road rate is the 'used in heavy vehicles for travelling on public roads' rate for liquid fuels for the applicable period, as published on ato.gov.au Off-road rate is the 'all other business uses' rate for liquid fuels for the applicable period, as published on ato.gov.au [7]

If you choose to use the BMHV for a particular vehicle in a tax period, you must only use that method for apportioning all fuel used in that vehicle to determine your fuel tax credits for that tax period. For example, you cannot use the BMHV and use the accepted percentages outlined in Practical Compliance Guideline PCG 2016/11 Fuel tax credits - apportioning taxable fuel used in a heavy vehicle with auxiliary equipment. [8]

If you use the BMHV you must be able to substantiate the diesel acquired. You must also be able to substantiate the kilometres travelled by using accepted records. [9]

The accepted records for substantiating the diesel acquired are one or more of the following provided they, whether individually or collectively, evidence both the quantity of diesel acquired for use in your business activities and that you acquired it: • tax invoices • receipts • fuel card statements • fuel supplier statements • bank statements.

The accepted records for substantiating the kilometres travelled on public roads are one or more of the following provided they show the kilometres travelled on public roads from the starting destination to the end destination: • reputable map sources (whether electronic, online or paper-based) • logbooks • odometer readings • contracts (showing where vehicles operate) • delivery dockets / job sheets / work diaries.

If you use the derived number of kilometres, the accepted records are any of the records listed in paragraph 15 of this Guideline that show total kilometres travelled - for example, logbooks and odometer readings.

You do not need to rely on global positioning systems and telematics technology to use the BMHV.

If you use the BMHV you must use the diesel consumption rate, which is the rate expressed in litres per kilometre from either: • Schedule 1 of this Guideline - accepted diesel consumption rates, or • the vehicle's engine diagnostic reports of 'driving fuel' economy.

We Deliver Pty Ltd (We Deliver) operates two diesel rigid refrigerated trucks, each with a gross vehicle mass (GVM) of greater than 4.5 tonnes. Each vehicle carries an average gross weight of 32 tonnes. The trucks undertake daily return trips from outer-Melbourne to Ballarat, five days a week.

In the December 2020 quarter tax period, We Deliver acquired 11,430 litres of diesel for use in the rigid trucks. This is shown on their fuel card statements. Over this period, We Deliver travelled a total of 32,000 kilometres and kept records (logbooks and details in their contracts) to show that 30,550 kilometres were travelled on public roads. This is shown in their logbooks and supported by details in their contracts.

We Deliver works out the 'litres of diesel used in the vehicles for travelling on public roads' as follows: 30,550 (Kilometres travelled on public roads) × 0.35 (Diesel consumption rate from Schedule 1) = 10,692.50 litres

Alternatively, We Deliver could have used the accepted percentage of 98.4% to determine the derived kilometres. This would have resulted in derived kilometres travelled on public roads of 31,488 (32,000 × 98.4%). Note, for this example using this approach would result in less fuel tax credits.

We Deliver works out the 'litres of diesel used in the vehicles off public roads' (including diesel used to power auxiliary equipment) as follows: 11,430 (Total litres of eligible diesel) - 10,692.50 (Litres of diesel used in a vehicle on public roads) = 737.50 litres

We Deliver works out 'fuel tax credits for the tax period' as follows: 10,692.50 litres × 16.5 cents per litre (Litres of diesel used in a vehicle on public roads × On-road rate*) + 737.50 litres × 42.3 cents per litre (Litres of diesel used in a vehicle off public roads × Off-road rate**) = $1,764.26 + $311.96 = $2,076.22 * The On-road rate (that is, the 'Used in heavy vehicles for travelling on public roads' rate) for the December 2020 quarter tax period is 16.5 cents per litre. ** The Off-road rate (that is, the 'All other business uses' rate) for the December 2020 quarter tax period is 42.3 cents per litre.
