Goods and Services Tax (GST) is a broad-based consumption tax applied to most goods and services sold or consumed in Australia. For businesses registered for GST, lodging GST returns is a critical aspect of tax compliance. Timely and accurate GST return filing ensures your business meets Australian Taxation Office (ATO) requirements and avoids penalties.This comprehensive guide will explain everything you need to know about how to Lodge GST Return in Australia including registration, lodgement methods, due dates, and best practices.
What is GST in Australia?
GST is a 10% tax on most goods, services, and other items sold or consumed in Australia. If your business has a GST turnover of $75,000 or more ($150,000 for non-profits), you must register for GST and regularly lodge GST returns.
GST applies to:
- Sales of goods and services
- Most digital products
- Leasing and hiring
- Professional and consulting services
Understanding GST obligations is essential to ensure your returns are correct and your input tax credits are maximized.
Who Needs to Lodge a GST Return in Australia?
Businesses Required to Lodge GST Returns:
- Australian businesses with GST turnover above $75,000
- Non-profit organisations with turnover above $150,000
- Ride-sharing and taxi drivers (regardless of turnover)
- Importers and exporters
If your business is registered for GST, you must lodge GST return in Australia either monthly, quarterly, or annually, depending on your ATO reporting cycle.
How to Register for GST
Before you lodge GST returns, your business must be registered for GST. You can register:
- Online via the Business Portal
- Through a registered tax or BAS agent
- By phone via the ATO
After registration, your business will receive a Business Activity Statement (BAS)—the primary form used for GST return filing in Australia.
Understanding Business Activity Statements (BAS)
BAS is the document through which you report your business’s tax obligations, including GST, PAYG withholding, PAYG instalments, and other tax obligations.
Key GST Sections on a BAS:
- G1: Total sales
- 1A: GST on sales
- 1B: GST on purchases
- G11: Non-GST purchases
You must report sales and purchases during your GST reporting period and calculate the net GST payable or refundable.
Methods to Lodge GST Return in Australia
1. Online via ATO Business Portal
Use your myGovID and Relationship Authorisation Manager (RAM) to access the Business Portal and submit your BAS.
2. Via Tax or BAS Agent
A registered agent can prepare and lodge on your behalf. This is highly recommended for complex business transactions.
3. Standard Business Reporting (SBR) Software
Accounting software such as MYOB, Xero, and QuickBooks allows direct BAS lodgement via integrated SBR.
4. Paper Lodgement
Available but discouraged by the ATO due to its slower processing time.
GST Reporting Periods
Your GST return filing frequency depends on your business turnover:
1. Monthly: Businesses with GST turnover of $20 million or more
2. Quarterly: Default option for most small to medium-sized enterprises
3. Annually: For businesses voluntarily registered with turnover below the threshold

- Q1 (Jul–Sep): 28 October

FAQs On Lodge GST Return in Australia
Question 1. What happens if I accidentally overpay my GST return in Australia?
Answer: If you overpay your GST return, you may be entitled to a refund or a credit on your next Business Activity Statement (BAS). The Australian Taxation Office (ATO) will usually apply any credits to your next tax obligation, or you can request a refund through the ATO’s online services. It’s important to check your records and notify the ATO promptly if an overpayment occurs.
Question 2. Can I lodge GST returns in Australia if I operate a business overseas but sell to Australian customers?
Answer: Yes, if you’re a non-resident business that sells goods, services, or digital products to Australian consumers, you may be required to register for GST and lodge returns in Australia. This includes businesses involved in e-commerce, SaaS, or online sales. The ATO provides a simplified GST registration and reporting system for overseas businesses.
Question 3. Is it mandatory to lodge a nil GST return if there are no transactions for the period?
Answer: Yes, even if you haven’t made any sales or purchases during a GST reporting period, you must still lodge a nil GST return. This confirms to the ATO that you were actively registered for GST during that time but had no activity. Failing to lodge a nil return can result in penalties or delays in your tax compliance record.
