Monthly BAS (GST & PAYG Withholding)
Businesses with GST turnover ≥ $20 million or large PAYG withholding obligations must lodge a Monthly BAS.
Each BAS is due on the 21st of the following month. It includes GST, PAYG Withholding, PAYG Instalments, and other taxes.
Late lodgment may result in penalties and interest, so it’s important to lodge and pay on time.
