Comprehensive Guide to GST in Australia (2024)
Goods and Services Tax (GST) is a broad-based tax of 10% applied to most goods, services, and other items sold or consumed in Australia. Introduced on 1 July 2000, GST replaced several indirect taxes and is administered by the Australian Taxation Office (ATO). This guide explains how GST works, when it applies, and how to calculate it correctly for your business or personal needs.
What is GST and How Does It Work?
GST is a value-added tax that applies to:
- Most goods and services sold in Australia
- Imports into Australia
- Certain international transactions
The current standard GST rate is 10%, though some items are GST-free (0%) or input-taxed (no GST credit). Businesses registered for GST (with turnover of $75,000 or more) must:
- Charge GST on their taxable sales
- Claim credits for GST included in business purchases
- Lodge regular Business Activity Statements (BAS)
When Do You Need to Register for GST?
You must register for GST if:
- Your business has a GST turnover of $75,000 or more
- Your non-profit organisation has a GST turnover of $150,000 or more
- You provide taxi or limousine travel (regardless of turnover)
- You want to claim fuel tax credits
GST-Free Items in Australia
Not all goods and services attract GST. Common GST-free items include:
| Category | Examples |
|---|---|
| Basic food | Bread, milk, fruit, vegetables, meat |
| Health services | Medical, dental, and hospital services |
| Education | School fees, course materials |
| Exports | Goods and services exported from Australia |
| Childcare | Approved childcare services |
How to Calculate GST Correctly
There are two main calculation scenarios:
1. Calculating GST from GST-Inclusive Amount
When you have a total that already includes GST (like most retail prices), use this formula:
GST Amount = Total Amount ÷ 11
Price Before GST = Total Amount – GST Amount
2. Calculating GST from GST-Exclusive Amount
When you have a price before GST (common in business-to-business transactions), use:
GST Amount = Price × 0.10
Total with GST = Price + GST Amount
Common GST Mistakes to Avoid
Businesses often make these GST errors:
- Not registering when turnover exceeds $75,000
- Claiming GST credits for private expenses
- Incorrectly treating GST-free items as taxable
- Failing to issue proper tax invoices
- Not accounting for GST on imports
GST for Different Business Types
| Business Type | GST Registration Threshold | Special Considerations |
|---|---|---|
| Sole Trader | $75,000 turnover | Can voluntarily register below threshold |
| Partnership | $75,000 turnover | Each partner shares GST liability |
| Company | $75,000 turnover | Must register if taxable |
| Non-Profit | $150,000 turnover | Special rules for charities |
| Taxi/Uber Driver | Immediate registration | Must register regardless of income |
GST Reporting and Payment
Registered businesses must:
- Lodge Business Activity Statements (BAS) regularly (monthly, quarterly, or annually)

- Pay any net GST owed to the ATO
- Keep records for 5 years
The ATO provides several methods for reporting and paying GST:
- Online through myGov or the Business Portal

GST for International Transactions

- Exports: Generally GST-free if exported within 60 days

Frequently Asked Questions
Is GST included in the price?
In Australia, prices displayed for consumers must include GST unless stated otherwise. Business-to-business prices may be quoted exclusive of GST.
Can I claim GST on business purchases?
Yes, if you’re registered for GST and the purchase is for your business (not private use). You claim these as input tax credits on your BAS.
What’s the difference between GST-free and input-taxed?
GST-free means no GST is charged (0% rate) but you can claim credits. Input-taxed means no GST is charged and you can’t claim credits (e.g., financial services, residential rent).
How often do I need to report GST?
Most small businesses report quarterly. Businesses with turnover over $20 million must report monthly. Some can choose annual reporting.
What happens if I don’t register for GST when required?
You may face penalties from the ATO, including back-payment of GST owed plus interest. You also can’t claim input tax credits for this period.
