Running a business in Australia right now often means watching fuel costs climb while trying to keep BAS lodgements clean and cash flow steady. ATO Fuel Tax Credit Rates 2025-26 matter because they can reduce the after-tax cost of eligible fuel, but only if you claim the right litres at the right rate and keep the records to prove it.

A lot of businesses either underclaim or overclaim. Underclaiming usually comes from poor apportionment, missed off-road use, or old rate assumptions. Overclaiming usually comes from treating all fuel the same, especially where a business has a mix of heavy vehicle road use, machinery use, and private or ineligible use.

Key Takeaways:

• Who can claim: Australian businesses using eligible taxable fuel in eligible business activities may be able to claim, but registration conditions apply.
• How claims are lodged: Fuel tax credits are generally claimed through your BAS.
• Records matter: Keep invoices, fuel receipts, logbooks, usage records, and calculation workings.
• Rates differ: The claim depends on fuel type and how the fuel was used, not just what fuel you bought.
• Road use and off-road use are not the same: Heavy vehicles on public roads can attract a different rate from machinery, plant, equipment, or other business uses.
• Always verify current rates: The ATO updates rates regularly, so don’t rely on memory or last quarter’s worksheet.

Introduction

If you’re a transport operator, tradie, farmer, contractor, or business owner with diesel and petrol bills piling up, fuel tax credits can make a real difference. They’re one of the more valuable business tax entitlements available, but they’re also one of the easiest to get wrong in practice.

The issue usually isn’t whether fuel was bought for business. The issue is classification. The ATO looks at fuel type, where it was used, and how it was used. A truck on a public road, an excavator on a site, and a generator at a job location may all involve diesel, but they won’t necessarily produce the same claim result.

Practical rule: Never treat fuel tax credits like a flat cents-per-litre refund. That shortcut causes errors.

The right approach is to work from your actual fuel use, map it to the ATO categories, calculate the claim carefully, and support it with records that would stand up in a review.

What Are Fuel Tax Credits

Fuel tax credits are a credit for fuel tax included in the price of taxable fuel used in eligible business activities. In practical terms, they let eligible businesses recover some or all of the fuel tax built into fuels such as diesel, petrol and certain other fuels when those fuels are used in qualifying activities.

Think of it as getting back part of a tax that was already built into the purchase price of fuel, but only where the law allows it. That’s why the same litre of fuel can produce a different result depending on whether it powered a heavy vehicle on a public road or machinery on a private site.

Where fuel tax credits usually apply

Common claim situations include fuel used in:

• Heavy vehicles: Road transport operations where the vehicle meets the relevant requirements.
• Machinery and plant: Excavators, loaders, pumps, compressors, and similar business equipment.
• Stationary equipment: Generators and engines used as part of business operations.
• Mixed-use operations: Businesses that run trucks and also use auxiliary equipment or off-road machinery.

Why businesses get confused

Many owners assume the fuel itself determines the claim. It doesn’t. The activity matters just as much as the fuel type.

Some heavy vehicle claims also depend on environmental criteria, so eligibility isn’t just about owning a truck and buying diesel. If your business has road use, private use, and off-road use across the same BAS period, you need a method that separates each category properly.

Getting the category right is often more important than getting the maths right. If the category is wrong, the calculation is wrong from the start.

Who Can Claim Fuel Tax Credits in Australia

A business can only claim fuel tax credits if it is registered for GST and uses taxable fuel in carrying on its enterprise. Eligibility then turns on what the fuel powered, where it was used, and whether the business can prove that use from its records. The ATO and business.gov.au guidance on fuel tax credits both point back to the same practical rule. Business use must be identified clearly, not assumed from the fuel purchase alone.

The businesses I see claim successfully usually have one thing in common. They separate fuel by activity before BAS time. That matters because the same diesel account can cover a road freight truck, a site generator, a skid steer, and a ute. Only some of that fuel may qualify, and some may qualify at a different rate.

Common claimants include businesses using fuel in:

• Heavy vehicle operations: Eligible vehicles used in transport activities, subject to the road use rules.
• Construction and civil works: Excavators, loaders, generators, pumps, compressors, and site plant.
• Primary production: Farm machinery, irrigation equipment, and other business equipment used on the property.
• Mining, quarrying and earthmoving: Plant and machinery operating away from public roads.
• Manufacturing and industrial operations: Stationary engines, plant, and equipment used in production.
• Trade and service businesses: Diesel-powered equipment used on jobs, not just fuel put into road vehicles.

Light vehicles are where many small business owners get caught. Fuel used in vehicles travelling on public roads is often not claimable if the vehicle is below the relevant threshold, even if the vehicle is used fully for business. By contrast, fuel used in eligible equipment, auxiliary engines, or light vehicles operating off public roads may still support a claim if the records and activity category are right.

Private use is excluded. Poor records can also sink an otherwise valid claim. If a business cannot show litres, dates, vehicle or equipment use, and a reasonable apportionment method, the ATO can reduce or deny the credit during a review.

A practical test helps. Ask three questions for each fuel purchase: was the business GST-registered, was the fuel taxable, and what exact business activity used it? If the answer to the third question is vague, fix that before lodging the BAS.

If you are reviewing fuel, vehicles, and other operating costs together, this tax deductions guide for Australian businesses helps separate fuel tax credit rules from ordinary income tax deductions.

ATO Fuel Tax Credit Rates for 2025-26

A common BAS error starts here. A business uses one diesel rate across all purchases for the quarter, then finds out some litres relate to heavy vehicles on public roads and other litres relate to plant, generators, or off-road equipment. The rate issue is usually an apportionment issue first.

Fuel tax credit rates change over time. The ATO updates rates and publishes the current tables in its fuel tax credit rates guidance. For BAS process and reporting controls, this BAS and GST reporting guide for businesses is also useful. Check the live ATO rate table for the exact period you are lodging. Do not rely on an annual summary or last quarter’s worksheet.

Rates for 2025-26 may change during the year and should not be treated as fixed until the ATO publishes the applicable period rates. The table below is illustrative only. Use it to understand the categories, not as a filing table.

Illustrative Fuel Tax Credit Rate Categories for 2025-26

Illustrative rates only. Always check the live ATO page for current, official rates before lodging your BAS.

Fuel / Activity	Example Use	FTC treatment
Heavy vehicle transport on public roads	Freight trucks carrying goods on public roads	Usually a reduced credit rate applies because of the road user charge
Off-road machinery and plant	Excavators, loaders, farm equipment, site plant	A higher credit rate may apply than for on-road heavy vehicle use
Petrol passenger vehicle on public roads	Standard car used for sales calls or admin travel	Often not claimable, or only claimable in limited circumstances depending on the vehicle and use
Diesel generator or auxiliary equipment	Generator at a construction site, refrigeration unit, auxiliary motor	May be claimable under a different activity category from the main vehicle

The practical point is simple. Rate selection follows fuel use, not just fuel type.

That is why high-volume businesses should split litres at source. If one fuel card account covers linehaul trucks, forklifts, generators, and utes, one blended rate across all diesel purchases is hard to defend in an ATO review. A better method is to map each asset or cost centre to an activity category, then apply the ATO rate that matches that use for the relevant BAS period.

Three checks usually prevent problems:

• Match each fuel purchase to the asset, equipment, or vehicle that used it
• Separate on-road heavy vehicle litres from off-road, auxiliary, and plant use
• Confirm the rate for the exact claim period before finalising the BAS

If records are weak, apply a conservative method and fix the coding before lodging. That usually costs less than amending BAS statements later or defending an overstated claim during an ATO audit.

How to Claim Fuel Tax Credits on Your BAS

A common BAS problem looks like this. The fuel invoices are in the file, the litres are real, but the claim amount cannot be explained back to vehicle use, plant use, or private use. That is the kind of gap the ATO focuses on.

Fuel tax credits are claimed through your BAS, but the BAS label is the last step, not the main job. The primary work is building a calculation that shows how you got to the figure, why each litre is eligible, and which rate applied during that BAS period. If the worksheet is weak, the BAS entry is weak.

For many businesses, BAS preparation breaks down in three places. Fuel is coded to one account with no split by activity. Corrections from earlier periods are handled informally. Staff rely on software totals without checking whether the fuel use category is right. Those shortcuts save time at month end, but they are hard to defend in a review.

Tools that make the process easier

The ATO fuel tax credit calculator is useful for working out current claims and corrections to earlier BAS periods. Xero, MYOB, and QuickBooks can help organise invoices, supplier feeds, and account coding, but they do not decide eligibility for you. A diesel purchase coded to “motor vehicle expenses” is still wrong if part of that fuel was used in a generator, forklift, or private travel.

If you need help with the reporting side, this guide to BAS and GST reporting for businesses works well alongside your fuel tax credit worksheets.

Rate timing and BAS review

Fuel tax credit rates can change during a financial year, and in some cases during a BAS cycle. When that happens, the claim may need to be split based on the relevant purchase or use dates, depending on the method applied and the facts of the business. Do not assume one rate covers the full quarter unless you have checked the ATO guidance for that exact period.

That matters for cash flow as much as compliance. A business with high fuel volume can overclaim or underclaim quickly if it applies a single rate across the whole BAS period without checking for changes. The safer approach is simple. Review the ATO rate for the claim period before lodging, keep a dated worksheet, and make sure any adjustment to a prior BAS is clearly documented.

If the claim is material, I would also check that the BAS figure can be traced back to litres by asset class or activity category, not just total fuel spend. That one step usually exposes the errors that lead to amendments later.

A Step-by-Step Process to Claim Fuel Tax Credits

A repeatable process is the best defence against both missed credits and ATO adjustments.

1. Confirm your eligibility
   Check that the business is registered appropriately and that the fuel was acquired for eligible business activities.
2. Pull all fuel purchase records for the BAS period
   Use fuel invoices, receipts, supplier statements, and internal purchase reports.
3. Separate business use from private use
   If any fuel was used privately, remove it before calculating the claim.
4. Split eligible fuel by activity type
   Separate heavy vehicle public road use from plant, equipment, generator, auxiliary, or other eligible business use.
5. Calculate eligible litres for each category
   Don’t claim based on dollars spent. Work from litres.
6. Apply the correct rate to each category
   Use the current ATO rate for the fuel type and activity.
7. Total the claim and report it on the BAS
   Enter the fuel tax credit amount in the relevant BAS fuel tax credit label.
8. Keep the supporting records
   Retain invoices, logbooks, odometer records, apportionment worksheets, and calculator outputs.

Quarter-end checklist

• Check coding: Make sure fuel accounts haven’t mixed road, off-road, and private use.
• Review equipment logs: Site machinery and generators are often missed.
• Reconcile litres: Compare litres claimed to litres purchased.
• Save your workings: A saved worksheet is easier to defend than a rough estimate.

Fuel Tax Credit Calculation Example

A construction business buys 12,000 litres of diesel in a quarter.

Its records show:

• 8,000 litres used in heavy vehicles travelling on public roads
• 3,000 litres used in an off-road excavator
• 1,000 litres used privately or otherwise ineligible

Using the example liquid fuel rates already noted above:

• 8,000 litres × 20.2 cents = $1,616
• 3,000 litres × 52.6 cents = $1,578

Total estimated fuel tax credit claim: $3,194

The 1,000 litres of private or ineligible use isn’t included.

Example only: Check current ATO fuel tax credit rates before lodging.

This is why apportionment matters. If the business had treated all litres as one category, the BAS claim would have been wrong.

Common Fuel Tax Credit Mistakes to Avoid

The expensive errors are usually small classification errors repeated over a full year.

The ATO rate structure for 1 July 2025 to 30 June 2026 creates a real gap between road and non-road claims. In the ATO table, heavy vehicle road use for liquid fuels is 20.2 cents per litre, while other business uses are 52.6 cents per litre. The ATO material also shows that where a business purchases 50,000 litres annually and 20% should have been treated as auxiliary use, misclassification can mean over $3,200 in lost credits annually, as shown in the ATO rate table for 2025-26.

Mistakes and quick fixes

• Mistake: Claiming fuel for private vehicle use.
  Quick Fix: Keep private and business fuel records separate from the start.
• Mistake: Using one rate for all diesel purchases.
  Quick Fix: Split road transport, auxiliary equipment, and off-road machinery before calculating.
• Mistake: Missing tax invoices or fuel receipts.
  Quick Fix: Reconcile supplier statements to invoices each BAS period and store digital copies.
• Mistake: Poor apportionment between business and non-business use.
  Quick Fix: Use logbooks, site records, odometer records, and equipment usage logs.
• Mistake: Claiming ineligible fuel use in light vehicles on public roads.
  Quick Fix: Review vehicle type and where the fuel was used before adding it to the BAS working.
• Mistake: Ignoring auxiliary equipment fuel.
  Quick Fix: Track separate fuel use for generators, pumps, refrigeration units, and similar equipment where relevant.

What usually triggers trouble

Claims become hard to defend when the worksheet says one thing and the business records say another. If litres purchased, kilometres travelled, and machinery hours don’t broadly line up, the claim needs review before the BAS is lodged.

Fuel Tax Credit Record-Keeping and Compliance Rules

A defensible claim starts with records. If the ATO asks how you worked out the claim, you should be able to show the documents and the method without rebuilding the file from scratch.

Records you should keep

Use this checklist for each BAS period:

• Tax invoices: Fuel purchase invoices showing supplier details and purchase information.
• Receipts and statements: Especially where fuel card accounts are used.
• Logbooks or odometer records: To support business use and road use calculations.
• Equipment usage records: For generators, plant, machinery, and other off-road assets.
• Calculation worksheets: Showing how litres were apportioned and which rates were used.
• BAS working papers: A record of the claim amount reported and how it ties back to source documents.

Key compliance points

Some claims for heavy vehicles also depend on environmental criteria. Road user charge adjustments can also affect the available credit, and in some situations the fuel tax credit can be reduced to nil where the road user charge exceeds the rate.

If you discover an error after lodging, don’t ignore it. Correcting a BAS is usually better than letting a weak claim sit on file. Businesses dealing with a review, audit query, or disputed position may also need support with ATO dispute resolution and response management.

Strong records do two jobs. They help you claim what you’re entitled to, and they help you prove why the claim was correct.

A simple compliance habit

Review fuel tax credits before lodging the BAS, not after. Once the BAS is filed, fixing preventable mistakes becomes slower and more stressful.

Frequently Asked Questions About Fuel Tax Credits

Who can claim fuel tax credits?

Eligible Australian businesses using taxable fuel in eligible business activities may be able to claim. Registration conditions apply, and business use must be supported by records.

Can sole traders claim fuel tax credits?

Yes, a sole trader may be able to claim if the registration and fuel use requirements are met. Sole trader status alone doesn’t prevent a claim.

Can I claim petrol fuel tax credits?

Sometimes. Petrol can be an eligible fuel, but the outcome depends on how and where it was used, not just the fact that petrol was purchased.

Can I claim fuel tax credits for my ute?

It depends on the vehicle and where it operates. Small business owners often assume every business vehicle qualifies, but public-road use in light vehicles is a common problem area.

Do I need fuel receipts?

Yes, you need proper records. In practice, that means keeping invoices, receipts, and enough supporting evidence to explain how you calculated the claim.

Can I claim fuel used in a generator?

Often yes, where the generator fuel is used in an eligible business activity. The classification still needs to be documented properly.

What if I made a mistake on a previous BAS?

Review the error and correct it using the appropriate BAS process. The ATO recommends using its calculator for both new claims and corrections.

Can accounting software calculate fuel tax credits automatically?

Software such as Xero, MYOB, and QuickBooks can help organise transactions and BAS data, but you still need to classify the fuel use correctly. Software won’t fix a bad apportionment method.

Are fuel tax credits taxable income?

The tax treatment can depend on the broader accounting and tax position of the business. Get advice before assuming how the credit should be treated in your return or financial statements.

What records does the ATO expect in a review?

The ATO will generally expect to see purchase evidence, usage records, calculation workings, and BAS support documents. The stronger the audit trail, the easier the review.

Conclusion

Fuel tax credits can be a valuable entitlement for transport businesses, tradies, contractors, farmers, and other Australian operators with eligible fuel use. The key is getting the basics right. Confirm eligibility, classify fuel correctly, use the current rate, and keep records that support every litre claimed.

If your business has mixed fuel use, multiple vehicles, site equipment, or past BAS errors, fuel tax credits should be reviewed carefully rather than estimated.
