Business Activity Statements (BAS) are one of the most important compliance obligations for Australian businesses. Lodge incorrectly or late and you'll face penalties from the ATO. Get it right and you'll maintain good standing while potentially claiming valuable GST credits.
What is a Business Activity Statement (BAS)?
A BAS is a form submitted to the ATO that reports your business's tax obligations including GST, PAYG withholding, PAYG instalments and other taxes.
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.
BAS lodgement deadlines & frequency
The ATO requires businesses to lodge BAS monthly, quarterly or annually, depending on your GST turnover and business structure.
