GST Rights and Obligations
Written in plain language for general understanding. This is educational content, not legal advice. Based on Commonwealth Acts of Parliament, federal regulations, and official government guidance.
What is this right?
The Goods and Services Tax (GST) is a 10% tax on most goods, services, and other items sold or consumed in Australia. It is governed by A New Tax System (Goods and Services Tax) Act 1999.
You must register for GST if your business has a GST turnover of $75,000 or more per year (or $150,000 or more for non-profit organisations). If your turnover is below these thresholds, registration is voluntary.
Once registered, you must charge GST on your taxable supplies, lodge a Business Activity Statement (BAS) — usually quarterly — and pay the GST you collected minus any GST credits you are entitled to on your business purchases.
Some items are GST-free, including most basic food, health services, education, and exports. Others are input-taxed, such as financial supplies and residential rent, meaning no GST is charged and no credits can be claimed.
If you are registered, you must issue tax invoices for sales of $82.50 or more (including GST) when requested by the buyer.
When does it apply?
This applies to businesses and sole traders operating in Australia.
- You must register if your annual GST turnover is $75,000 or more.
- Taxi and rideshare drivers must register for GST regardless of turnover.
- You can voluntarily register below the threshold to claim GST credits on business purchases.
What should you do?
- Register for GST through the Australian Business Register (ABR) if required.
- Lodge your BAS on time — quarterly BAS is due 28 days after the end of each quarter.
- Issue tax invoices for taxable sales of $82.50 or more when requested.
- Claim GST credits on business purchases — keep tax invoices as evidence.
- Separate GST-free and input-taxed items in your accounting records.
What should you NOT do?
- Don't charge GST if you are not registered — it is an offence to collect GST without being registered.
- Don't claim GST credits on private purchases — only business expenses qualify.
- Don't ignore your BAS — late lodgement attracts penalties and interest from the ATO.
- Don't charge GST on GST-free supplies such as basic food and medical services.
- Don't forget to cancel your registration if your turnover drops below $75,000 and you no longer wish to be registered.
