BAS Lodgement Explained: A Guide for Small Business Owners
Business Activity Statements (BAS) form an important part of Australia’s tax system. If your business is registered for GST, you will generally need to lodge a BAS to report GST, PAYG withholding and other tax obligations.
Understanding how BAS works can help business owners remain compliant and avoid costly mistakes.
What Is a BAS?
A Business Activity Statement is a form submitted to the Australian Taxation Office that reports:
- GST collected on sales
- GST paid on business purchases
- PAYG withholding
- PAYG instalments
- Other tax obligations where applicable
Most small businesses lodge BAS quarterly, although some businesses lodge monthly.
Who Needs to Lodge BAS?
Businesses registered for GST are generally required to lodge BAS.
This includes many:
- Sole traders

Registration for GST is generally required once turnover exceeds the registration threshold.
