• Instalment amount at G21

    We have calculated your GST instalment amount at G21 on your instalment notice. This is based on GST information in your last annual GST return, or net GST amounts you have reported to us previously.

    Attention

    This amount is adjusted under the law, in line with changes in Australia's gross domestic product (GDP).

    End of attention

    You can vary your instalment amount

    If you think the instalment amount pre-printed at G21 is more (or less) than your expected annual GST liability for the year, you can vary the amount (see Varying your instalment amount).

    You do not have to vary your instalment amount; you can simply pay the amount at G21 each quarter and make a balancing payment (or receive a refund) when you lodge your annual GST return.

    If you pay the GST instalment amount we advise by the due date, you will not incur penalties.

    Attention

    You may incur penalties if you vary your GST instalment amount and you underestimate your annual GST liability.
