Understanding GST Registration and BAS Lodgment
Goods and Services Tax (GST) is a 10% tax on most goods, services and other items sold or consumed in Australia. If your business meets certain criteria, you must register for GST and lodge Business Activity Statements (BAS) to report and pay GST, PAYG instalments, PAYG withholding and other taxes.
Who Must Register for GST
You must register for GST if you:
- Have a GST turnover of $75,000 or more (or $150,000 for non-profit organisations)
- Start a new business and expect your GST turnover to meet the threshold in the first 12 months
- Provide taxi or limousine travel (including ride-sourcing) regardless of turnover
- Want to claim fuel tax credits for your business
When and How to Register
If you meet the criteria, register within 21 days of becoming liable. You’ll need an ABN first. You can register for GST:
- Online via the ATO Online Services for Business
- By phone on 13 28 66
- Through your registered tax or BAS agent
You only register once, even if you operate multiple businesses. If your circumstances change, you can cancel your GST registration or apply to backdate it by up to four years (subject to conditions).
What Is a Business Activity Statement (BAS)?
A BAS is the form businesses use to report and pay:
- Goods and Services Tax (GST)
- Pay As You Go (PAYG) instalments
- PAYG withholding tax
- Other taxes such as luxury car tax or wine equalisation tax
The ATO automatically sends you a BAS when it’s time to lodge, based on your GST registration and reporting cycle.
When to Lodge Your BAS
BAS reporting periods are typically quarterly, but some businesses may report monthly or annually. You must lodge and pay any amounts owing by the due date to avoid penalties. If you need extra time, you may be eligible for the ATO’s Two-Week Lodgment Deferral.

- Online:
