  • Rates – business

    Fuel tax credit rates change regularly. They are indexed twice a year, in February and August, based on the upward movement of the consumer price index.

    The CPI indexation factor for rates from 3 August 2020 is 0.9850. As the factor is less than one, the rates do not change.

    Rates did not change in July for fuel used in a heavy vehicle for travelling on public roads. There was no change to the road user charge.In July, rates changed for biofuels due to an annual increase in excise duty rates.
