This comprehensive guide explains everything you need to know about BAS lodgement in Australia—what it is, when it's due, how to complete it correctly, and why professional BAS services can save you time, money, and stress.
What is a Business Activity Statement (BAS)?
A Business Activity Statement (BAS) is a form submitted to the Australian Taxation Office (ATO) that reports your business's tax obligations including GST, PAYG withholding, PAYG instalments, and other taxes.
What BAS Reports
- GST Collected: GST charged on your sales
- GST Paid: GST paid on your purchases
- PAYG Withholding: Tax withheld from employee wages
- PAYG Instalments: Prepayments towards your annual tax bill
The BAS calculates whether you owe money to the ATO or whether the ATO owes you a refund. If you've paid more GST on purchases than you've collected on sales, you'll receive a refund.
