Instalment Activity Statements

An Installment Activity Statement or IAS is a form frequently used by the taxpayers who are not lodged for the GST. The IAS is even the form lodged by the entities that are engaged in preparing a quarterly BAS but are needed to forward their PAYG withholding tax every month since they are a medium withholder. The IAS is a molded document issued by the ATO monthly and it outlined the amount of PAYG installments, PAYG withholding, and ABN withholding.

Who uses Instalment Activity Statement?

If you are business or individual that follows PAYG installments, PAYG withholding, and/or FBT Installments and are not lodged for GST you will be required to lodge IAS. It is even possible if you are a trustee. For example you will be required to compile a combination of both business activity statements (BAS) and IAS forms.


The ATO will dispatch all your documents in advance which provide you sufficient time to complete it and get it lodged before the scheduled date. Also, ensure to fill some of your personal information beforehand. This can save your lot of time
