Fuel tax credit rates for business
Before you claim fuel tax credits, check if you are eligible to claim using our eligibility tool.
Fuel tax credit rates change regularly.
Using the fuel tax credit calculator is the easiest way to calculate:
- what you can claim in your business activity statement (BAS)
- an adjustment or correction for a previous BAS.
Fuel tax credit rates are indexed twice a year – in February and August – in line with the consumer price index (CPI)External Link. The CPI indexation factor for rates from 2 February 2026 is 1.019.
Fuel tax credit rates also change for fuel used in a heavy vehicle for travelling on a public road due to changes in the road user charge. This affects both liquid fuels (such as petrol and diesel) and gaseous fuels (such as liquefied natural gas or LNG).
Rates for biodiesel (B100) will also change each financial year until 1 July 2030.
Note: Fuel excise duty was temporarily reduced from 30 March 2022 to 28 September 2022. This reduction applied to excise and excise equivalent customs duty rates for petrol, diesel and all other fuel and petroleum-based products (except aviation fuels). This affected the fuel tax credit rates during that period.

Claiming past fuel tax credits
There are time limits for:
- claiming fuel tax credits
- making adjustments and correcting errors.
You need to claim your fuel tax credits within 4 years of the due date of the earliest BAS in which you could have made your claim. If you don't claim the credits within that time, you'll no longer be eligible to claim them.
Use the fuel tax credit calculator to easily work out the amounts for your BAS up to 4 years ago.
