These instructions and examples will assist you when completing your quarterly goods and services tax (GST) instalment notice (Form S).
You will have received a quarterly GST instalment notice because you:
- report and pay your GST instalments quarterly
- use the GST instalment amount to report
- have no other reporting requirements.
Instalment amount at G21
We calculate 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.
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.
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.
You may incur penalties if you vary your GST instalment amount and you underestimate your annual GST liability.
Paying the instalment amount calculated by us
To pay the GST instalment amount calculated by us at G21 on your instalment notice, you need to:
- transfer the instalment amount at G21 to the 'Amount paid' section of the payment advice
- pay the amount by the date shown in the 'Payment due on' section at the front of the instalment notice (using one of the How to pay options on the instalment notice)
- keep the instalment notice for your records (do not return it to us).
If you pay the GST instalment amount pre-printed on the instalment notice, there is nothing else you need to do for this quarter.
