    Question 2

    It is not compulsory to provide the Australian business number (ABN) or excise identification number (EIN) for the person or business liable to pay excise duty, but it will help us process your amendment quickly.

    If the business is a trust, enter the ABN or EIN of the trustee in its capacity as trustee of the trust.

    Question 3

    Question 4

    Provide your permission number and the settlement period of the return you want to amend.

    Indicate if the return you are amending was a nil return (that is, you originally reported that no goods were delivered into home consumption during the settlement period).

    If you do not have a periodic settlement permission

    Provide the original return number of the return you want to amend. This number is on your delivery authority.

    Question 5

    Describe the reason for the amendment – for example, detection of an error in transcribing the quantity dispatched.

    Product details

    Label B: Quantity in dutiable units (other than blended fuels)

    The quantity in dutiable units (or dutiable quantity) is the amount or volume of product you have delivered into home consumption and are liable to pay excise duty on.

    Most excise tariff items listed in the tariff schedule have a specified measurement unit known as a dutiable unit. Dutiable units include:

    • kilograms of compressed natural gas
    • litres of fuel (other than blended fuels)
    • litres of alcohol.

    As excise duty is not payable on the first 1.15% of alcohol content in beer, use the following formula when calculating the dutiable quantity of beer products:

    Total litres of beer × (alcohol strength − 1.15%) = dutiable quantity

    For products other than alcohol, report dutiable quantity to two decimal places. For alcohol products, report to one decimal place.

    Provide the quantity in dutiable units at label B.

    Label B: Quantity in dutiable units (blended fuels including biofuel blends)

    Blended fuels are products listed under tariff item numbers 10.710.12 and 10.30.

    The dutiable quantity for blended fuels is the total quantity of the blend in litres, regardless of whether duty has been paid.

    Report dutiable quantity for blended fuels to two decimal places.

    Provide the total quantity of the blend at label B.

    Label C: Statistical quantity (for blended fuel including biofuel blends)

    Excise tariff items for blended fuel also have a second measurement unit type, known as statistical quantity.

    The statistical quantity is the proportion of the blended product which is biodiesel, ethanol or water. Report this as a whole amount with no decimal places.

    Provide the statistical quantity of the product at label C.

    Label D: Duty rate

    Each excise tariff item listed in the tariff schedule has a rate of excise duty.

    If you don't know which tariff item applies, refer to the applicable excise rates

    If you need further help, you can contact us about excise and EEGs.

    Provide the relevant rate of excise duty for your product at label D.

    Label E: Excise amount

    The excise amount is the amended excise liability (if any) for each line entered on the form. When you fill in the form online, for products other than blended fuels, the excise amount is calculated for you (multiplying the quantity in dutiable units (label B) by the rate of excise duty (label D).

    If you are reporting blended fuels, deduct any excise duty previously paid and provide the net amount at label E.

    Excise duty summary

    Total amended excise amount

    This is the total excise duty for this settlement period. It may not represent the amount of excise owing, or previously overpaid, as a result of the amendments made on the form.

    Total amount owing or overpaid

    If there is an overall credit, state which of the following payment methods you would prefer:

    • refund the amount (by cheque or electronic funds transfer [EFT])
    • apply the amount to existing or future liability.

    If the amendment results in a credit, the amount you receive may differ from the total amount calculated. This will occur when it is necessary to adjust for other tax debts or some Australian Government debts.

    If the amendment results in a debit, the amount shown as the total amount is the amount you must pay to us.

    Bank account details

    Complete this section if you expect to receive a refund of excise duty. The bank account must be held in the name of the person or business that paid the excise duty.


    You, or a person who is your agent, must sign the declaration.

    If you lodge this form via Online services for business, your electronic credential will be accepted as your electronic signature. You will not need to sign the declaration on the form.
