ATO Fuel Tax Credit Rates 2025-26: Who Can Claim And How

Running a business in Australia often means dealing with rising fuel costs while trying to keep BAS lodgements accurate and cash flow under control.
For many transport operators, tradies, contractors, farmers, and construction businesses, fuel tax credits can reduce operating costs significantly. But they are also one of the most commonly misunderstood business tax claims.

Some businesses miss out entirely. Others overclaim because they apply the wrong rates or fail to separate eligible and ineligible fuel use properly.

  • The key is understanding that fuel tax credits depend on:
  • • The type of fuel
  • • How the fuel was used
  • • Where the fuel was used
  • • Whether proper records exist

What Are Fuel Tax Credits?

Fuel tax credits are designed to help eligible businesses recover part of the fuel tax included in the price of taxable fuel used for business activities.
In simple terms, businesses may be able to claim credits for fuels such as:

  • • Diesel
  • • Petrol
  • • Certain gaseous fuels

when those fuels are used in eligible business operations.

However, the claim is not simply based on buying fuel.

The ATO looks closely at:

  • • What the fuel powered
  • • Whether the use was on-road or off-road
  • • Whether the fuel use was business-related
  • • Whether the activity qualifies under fuel tax credit rules

  • Why Many Businesses Get Fuel Tax Credits Wrong

One of the biggest mistakes businesses make is treating all fuel the same.
But fuel tax credit rates can vary depending on:

  • • Road use
  • • Off-road use
  • • Heavy vehicles
  • • Auxiliary equipment
  • • Generators
  • • Plant and machinery
  • Example
  • A business may purchase diesel for:
  • • A heavy truck on public roads
  • • An excavator on a construction site
  • • A generator powering equipment
  • Even though all use diesel, the fuel tax credit treatment may differ.

ATO Fuel Tax Credit Rates 2025-26

Fuel tax credit rates change regularly and should always be verified using current ATO guidance before lodging your BAS.

Typical Fuel Tax Credit Categories

Fuel Use Example FTC Treatment
Heavy vehicles on public roads Freight transport Reduced rate may apply
Off-road machinery Excavators, loaders, farm equipment Higher rate may apply
Auxiliary equipment Refrigeration units, generators Different eligible category
Light vehicles on public roads Standard passenger vehicles Often limited or non-claimable

The important point is this:

Fuel type alone does not determine the claim.
The business activity matters just as much.


How To Claim Fuel Tax Credits On Your BAS

Fuel tax credits are generally claimed through your BAS.

But the BAS label is only the final step.

The real work happens before lodgement.

A Proper FTC Process Usually Includes

  • Collecting all fuel invoices and receipts
  • Separating business and private use
  • Splitting on-road and off-road fuel usage
  • Calculating eligible litres
  • Applying the correct ATO rate
  • Keeping worksheets and supporting records

Businesses relying only on accounting software totals without reviewing fuel use categories can easily create BAS errors.


Step-By-Step Fuel Tax Credit Process

Step 1 — Confirm Eligibility

Check that your business is registered and the fuel use qualifies.

Step 2 — Gather Fuel Records

Collect invoices, receipts, supplier statements, and fuel card reports.

Step 3 — Separate Fuel Use

Split:

  • Business use
  • Private use
  • Road use
  • Off-road use

Step 4 — Calculate Eligible Litres

Claims should be based on litres used, not simply fuel spend.

Step 5 — Apply Correct Rates

Use the applicable ATO rate for the relevant BAS period.

Step 6 — Lodge Through BAS

Enter the final fuel tax credit amount correctly in your BAS.

Step 7 — Retain Supporting Records

Keep:

  • Logbooks
  • Worksheets
  • Equipment records
  • Odometer logs
  • Fuel invoices

Common Fuel Tax Credit Mistakes

Frequent Problems Businesses Face

  • Claiming all diesel under one rate
  • Including private vehicle fuel
  • Poor record keeping
  • Missing invoices
  • Incorrect apportionment methods
  • Ignoring generator or auxiliary equipment fuel
  • Treating software totals as automatically correct

These errors often create:

  • BAS amendments
  • ATO review issues
  • Reduced claims
  • Overclaim risks

Record Keeping Is Critical

Strong records are one of the most important parts of any fuel tax credit claim.

Records Businesses Should Keep

  • Fuel invoices and receipts
  • Fuel card statements
  • Vehicle logbooks
  • Odometer records
  • Equipment usage logs
  • Calculation worksheets
  • BAS support documents

The stronger the audit trail, the easier it is to support the claim if reviewed by the ATO.


Fuel Tax Credit Calculation Example

A construction business purchases 12,000 litres of diesel during a BAS period.

Its records show:

  • 8,000 litres used in heavy vehicles on public roads
  • 3,000 litres used in excavators
  • 1,000 litres used privately

Only the eligible business fuel is included in the claim.

This example highlights why fuel apportionment is essential.

If the business applied one rate to all litres, the BAS claim could become incorrect.


Final Thoughts

Fuel tax credits can create substantial savings for eligible Australian businesses.

But they should never be treated as a simple cents-per-litre refund.

The safest approach is to:

  • Classify fuel correctly
  • Use current ATO rates
  • Maintain strong records
  • Separate eligible and ineligible fuel use carefully
  • Review BAS calculations before lodging

Businesses with mixed fuel usage, heavy vehicles, generators, machinery, or prior BAS errors should review fuel tax credit calculations carefully before claiming.
