The Government temporarily halved the excise and excise equivalent customs duty rates for petrol, diesel and all other petroleum-based products (except aviation fuels) for 6 months from 30 March 2022 until 28 September 2022. This has caused a reduction in fuel tax credit rates.
During this 6 month period, businesses using fuel in heavy vehicles for travelling on public roads won't be able to claim fuel tax credits for fuel used for this purpose. This is because the road user charge exceeds the excise duty payable, and this reduces the fuel tax credit rate to nil.
You can find the ATO’s updated fuel tax credit rates that apply for the period from 30 March 2022 to 30 June 2022 here. The ATO’s fuel tax credit calculator has been updated to apply the current rates.
