👤 Who Needs to Lodge a BAS?
You generally need to register for GST and lodge a BAS if:
| Situation | Threshold | Required? |
|---|---|---|
| 🏢 Regular Business | $75,000+ turnover | ✅ Yes |
| 🤝 Non-Profit | $150,000+ turnover | ✅ Yes |
| 🚕 Taxi/Rideshare | Any turnover | ✅ Yes |
| 🌱 Voluntary Registration | Any turnover | 🟡 Optional |
💡 Tip: Even if below the threshold, voluntary GST registration can be beneficial for claiming input tax credits!
🆚 BAS vs. IAS: What's the Difference?
An Instalment Activity Statement (IAS) is a simpler form typically used by businesses not registered for GST but still needing to report other obligations like PAYG withholding or PAYG instalments.
🔍 Breaking Down the BAS: Key Components Explained
Understanding the main sections is essential to successfully navigating your BAS:
💰 Goods and Services Tax (GST)
📊 GST Basics:
- What is GST? A 10% tax applied to most goods and services sold or consumed in Australia
- GST Collection: You charge GST to customers on taxable sales
- GST Credits: You can claim back GST paid on business purchases
📋 Key BAS Labels:
| Label | Description | What to Report |
|---|---|---|
| G1 | Total Sales | All business sales (including GST) |
| 1A | GST on Sales | GST you've collected from customers |
| 1B | GST on Purchases | GST credits you're claiming |
🧮 The GST Calculation:
Net GST = GST Collected (1A) - GST Paid (1B)
- Positive result: You owe GST to the ATO
- Negative result: You're due a GST refund
⚠️ Important: You must have valid tax invoices to claim GST credits!
👥 Pay As You Go (PAYG) Withholding
- What is PAYG Withholding? This is the tax you withhold from payments made to employees, directors, or certain contractors.
- Reporting: You report the total gross wages and other payments (label W1) and the total amount of tax you withheld (label W2 or W4).
📈 Pay As You Go (PAYG) Instalments
- What are PAYG Instalments? These are regular prepayments towards your expected annual income tax liability.
- Reporting: The ATO typically pre-fills an instalment amount (Option 1) or rate (Option 2) on your BAS. You report this at label 5A or calculate using the rate at 5B.
🔄 Other Potential Taxes & Credits
Depending on your specific business activities, your BAS might also include sections for:
- Fringe Benefits Tax (FBT) Instalment
- Wine Equalisation Tax (WET)
- Luxury Car Tax (LCT)
- Fuel Tax Credits (FTC)
