    Fuel tax credit rates for business

    Fuel tax credit rates change regularly so it's important to check and apply the correct rate.

    They are indexed twice a year – in February and August – based on the upward movement of the consumer price index (CPI). The CPI indexation factor for rates from 1 February 2023 is 1.037.

    Fuel tax credit rates may also change for fuel used in a heavy vehicle for travelling on a public road due to changes in the road user charge. The charge is reviewed annually and the change, if made, generally occurs in July.

    In July 2023, rates will change for biodiesel (B100) due to an annual increase in excise duty rates.

    From 29 September 2022, the rates changed due to the end of the temporary reduction of fuel excise duty. The reduction was in place from 30 March to 28 September and 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 this period.

    Current fuel tax credit rates

    Past fuel tax credit rates

    There are time limits for claiming fuel tax credits, making adjustments and correcting errors – generally, you must claim or amend your claim within 4 years.
