I have recently been required to lodge IAS returns (August and September) on behalf of my employer and it pre-populates with the PAYG W (employee withheld amounts) do I need to lodge an IAS in October for September or is this months figure to be entered in the BAS and no IAS lodged for October as both are due on different dates.
Hi @Mary_E,
It sounds like your employer is registered to lodge monthly BAS with PAYG withholding and quarterly IAS. The monthly PAYGW as you've said is amounts withheld for employees whereas the lodgements of IAS (instalment activity statements) are for your employer to pay their tax. So, all BAS and IAS will need to be lodged as required.

Hi AnitaATO
Now I'm completely confused my understanding is the IAS is to report PAYG, in my employer case currently the only PAYG withheld is from employees and not a tax instalment payment of the employers? My employer still is only required to lodge BAS quarterly. So do I need to lodge IAS every month and exclude wages and PAYG from the quarterly BAS?
