    • gifts
    • trust and partnership distributions you receive
    • tax refunds
    • government pensions, allowances and payments.


    Most businesses can choose whether to include or exclude the GST component when reporting their taxable sales - select the 'yes' or 'no' at label G1.

    If you have no sales for the reporting period, enter '0' at G1.

    G2 - Export sales

    Export sales to report at G2 are:

    • the free on-board value of exported goods that meet the GST-free export rules
    • payments for the repairs of goods from overseas that are to be exported
    • payments for goods used in the repair of goods from overseas that are to be exported.

    All amounts reported at G2 should also have been reported at G1.

    Don't report at G2 any of the following:

    • amounts for GST-free services, unless they relate to the repair, renovation, modification or treatment of goods from overseas whose destination is outside Australia
    • amounts for freight and insurance for transport of the goods outside Australia, or other charges imposed outside Australia in the free on-board value
    • amounts for international transport of goods or international transport of passengers.

    If these items are GST-free, they should be reported at G3.

    G3 - Other GST-free sales

    GST-free sales include things such as:

    • most basic foods
    • health and education services
    • certain childcare services.

    Report at G3 all GST-free sales (other than export amounts shown at G2) that you've made. Amounts reported at G3 should also have been reported at G1.

    G10 - Capital purchases

    Capital purchases include things such as:

    • land and buildings
    • machinery
    • cash registers
    • computers
    • cars.

    G11 - Non-capital purchases

    Non-capital purchases include trading stock and normal running expenses, such as:

    • stationery and repairs
    • equipment rentals
    • leases.

    If your GST turnover is expected to be equal to or greater than $1 million, you need to separately report your capital and non-capital purchases at G10 and G11.

    If your GST turnover is expected to be less than $1 million, you can either:

    • continue to separately report your capital and non-capital purchases at G10 and G11 using the current breakdown in your records, or
    • record capital items costing more than $1,000 at G10 and non-capital items costing $1,000 or less at G11.

    G21-G24 - Option 3: pay GST instalment amount

    If you have chosen option 3 to report your GST (pay instalment amount quarterly and report annually), the pre-determined GST instalment amount is shown at G21. Simply copy this to 1A.

    If you think that the total of your advised instalment amounts will be more (or less) than your actual GST liability for the year, you can vary your instalment amount.

    To vary your instalment amount you need to:

    • calculate your estimated annual GST liability and enter this at G22
    • calculate your instalment amount for the quarter - this depends on the number of quarters remaining in the year and the amount of instalments you've already paid; enter this amount at G23
    • indicate your reason for varying by entering the appropriate reason code at G24.

    1A - GST on sales or GST instalment

    Report at 1A the total amount of GST (including any relevant adjustments) you're liable to pay us for the reporting period.

    If you have no GST on sales or adjustments for the reporting period, enter '0'.

    If you report and pay GST quarterly using option 3 (the instalments option), report at 1A your GST instalment amount displayed at G21. If you've varied this amount, take the figure from G23 and report this amount at 1A.

    If you use option 3, you must also lodge an Annual GST Return at the end of the financial year and account for any difference between the following:

    • your total GST instalments for the year
    • your actual GST liability.

    In your Annual GST Return, report the total amount of GST on your sales plus any relevant adjustments at 1A.

    1B - GST on purchases

    You report at 1B the total amount of GST credits (including any relevant adjustments) you're eligible to claim from us.

    If you have no GST on purchases or adjustments for the reporting period, enter '0'.

    If you use option 3 (the instalments option), you won't need to complete 1B on your quarterly BAS. However, you must complete this box on your Annual GST Return at the end of the financial year.

    Your GST net amount is GST on sales (label 1A) + WET (label 1C) + LCT (label 1E) minus GST on purchases (label 1B) + WET refundable (label 1D) + LCT refundable (label 1F).

    If you are a GST instalment payer, the total GST instalments paid by you (label 1H) are taken into account when calculating your GST net amount.
