Business Activity Statement / Installment Activity Statement
Businesses in Australia use a business activity statement (BAS) or instalment activity statement (IAS) to report and pay different taxes to the Australian Taxation Office (ATO). In summary, it’s a streamlined tax form that makes things easier to process ie. GST, PAYG withholdings, PAYG instalments and other forms of taxes. The amount of tax liabilities and the size of the firm can affect how frequently a BAS/IAS is lodged or filed. Although it’s usually done quarterly, some companies can need to file monthly or yearly.
