You can prepay amounts towards your expected tax bill. Pre-payments can help you stay on top of your tax and avoid falling into debt. To make a pre-payment, you simply need to:
get the correct payment reference number
decide how much to pay
choose a payment method.
You must use the correct payment reference number to ensure ATO credit the right account. You can find the number on the relevant notice or payment slip received from ATO, or you can access it from the portals.
