There are several ways to pay your BAS bill, although in most cases companies will choose to pay by BPAY, credit or debit card. Additionally, you can make voluntary prepayments to reduce the amount you need to pay for your next BAS return. So if you’ve had a particularly good fiscal quarter, it might be a good idea to start paying your next quarter’s BAS.

Please note that the ATO may impose penalties if you make mistakes in your BAS. These penalties can be severe if the ATO determines that the errors are due to ignorance of tax laws or negligence. However, legitimate or honest mistakes should be reported for the sake of the amount you missed.
