Fuel Tax Credits for Australian Tradies: The Claim Most Sole Traders Are Missing

Fuel tax credits are one of the least well-known tax benefits available

to Australian trade business owners -- and one of the most commonly

missed. If you use fuel for business purposes in plant, equipment,

tools, or heavy vehicles off public roads, you may be entitled to a

direct cash rebate from the ATO on the excise embedded in that fuel.

This isn't a deduction -- it's a direct credit. It reduces your BAS

liability dollar for dollar. And for tradies who use significant

quantities of fuel in their business, the annual value can be

substantial.

What Are Fuel Tax Credits?

When you buy fuel in Australia, you pay a federal excise tax embedded in

the pump price. Fuel tax credits allow businesses to claim back all or

part of that excise on fuel used for certain eligible purposes.

The concept is that the fuel excise partly funds roads and road

infrastructure -- so fuel used off public roads or in non-transport

equipment shouldn't attract the full road user component of excise. Fuel

tax credits return that portion to businesses.

Which Tradies Are Eligible?

You're likely eligible for fuel tax credits if your trade business

involves any of the following:

• Operating plant or machinery powered by petrol or diesel --

generators, compressors, concrete pumps, cranes, forklifts, welders,

or similar equipment used on job sites

• Using heavy vehicles (4.5 tonnes GVM or more) off public roads, or

on public roads for certain eligible activities

• Using fuel-powered tools such as petrol saws, grinders or cleaning

equipment in a business context

• Running diesel-powered site vehicles such as forklifts, skid steers,

mini excavators, or similar off public roads

You cannot claim credits for fuel used in light vehicles (under 4.5

tonnes GVM) travelling on public roads -- your regular ute or van

travelling to and from job sites doesn't qualify for credits, though it

is still a tax deductible expense in the normal way.

How Much Are the Credits Worth?

Fuel tax credit rates are set by the government and indexed quarterly to

the Consumer Price Index. As at 2025-26, rates vary by fuel type and

use:

• Fuel used in plant, machinery, equipment or heavy vehicles (off

public roads): the rate is approximately 50-55 cents per litre for

liquid fuels, which represents most of the excise embedded in diesel

and petrol.

• Fuel used in light vehicles travelling on public roads: nil. You

can't claim the credit, but the fuel cost is still a deductible

expense.

Always check the current rates on the ATO website at the time of

claiming, as rates change quarterly. The ATO has an online fuel tax

credit calculator that applies the correct rate for the period.

Who Can Claim?

To claim fuel tax credits, you must be registered for GST and you must

be claiming the credit for fuel used in a business activity. The credit

is claimed on your BAS -- there's no separate form. You simply include

the amount in the fuel tax credit field of your BAS, and it reduces the

net amount payable to the ATO (or increases your refund).

You need to be able to substantiate the fuel quantities used in eligible

equipment. Keep fuel purchase records (receipts or bank statements

showing fuel purchases) and if possible maintain a log of what fuel went

into what equipment. For larger claims, more detailed record-keeping is

important.

How to Calculate Your Claim

The calculation is straightforward: quantity of eligible fuel (in

litres) multiplied by the applicable rate per litre equals your fuel tax

credit for the period.

For example: If you used 500 litres of diesel in an on-site generator

during a quarter at a credit rate of 50 cents per litre, your fuel tax

credit for that quarter would be $250. This reduces your BAS payable by

$250 directly.

Over a year, a tradie running a diesel generator 3-4 days per week might

use 2,000-4,000 litres of diesel in that equipment alone -- a fuel tax

credit of $1,000-$2,000 per year. For a trade business running multiple

pieces of plant equipment, the annual credit can be much larger.

Common Mistakes and Gotchas

The most common mistake is claiming credits for fuel used in light

vehicles on public roads -- this is not eligible and can attract ATO

penalties. The second most common error is using the wrong rate -- the

rates change quarterly, so you must use the rate current at the time of

fuel acquisition, not a single rate for the whole year.

A third issue is failing to keep adequate records. If you're audited,

the ATO will expect you to demonstrate the quantity of fuel used in

eligible equipment. A reasonable record-keeping system -- even a simple

logbook noting date, equipment, and fuel quantity -- is sufficient for

most small trade businesses.

Fuel Tax Credits and Your Accountant

Despite being a relatively simple claim, fuel tax credits are widely

missed simply because many small trade business accountants don't

proactively ask about equipment fuel use when setting up a client's BAS

process. It's worth specifically raising the question: "Am I eligible

for fuel tax credits given the equipment I use?"

If you haven't been claiming and you were eligible, you can amend your

previous BAS returns for up to four years to recover credits you missed.

The ATO has a specific process for this and it's a legitimate and

accepted practice.

Getting Started

If you use petrol or diesel-powered plant equipment in your business, go

to the ATO website and use the fuel tax credit eligibility tool and

calculator. It will walk you through the eligibility questions for each

type of fuel use in your business and calculate the credit amount.

Then add the fuel tax credit line to your standard BAS process. It's a

five-minute addition to your quarterly BAS preparation that can return

real money to your business every quarter. For eligible tradies, it's

one of the most straightforward and underutilised cash benefits in the

Australian tax system.
