PAYG Instalments Australia 2026: Complete Guide for Businesses
Managing tax in Australia can feel overwhelming—especially when a large, unexpected tax bill hits at the end of the financial year.
If you’ve ever faced that kind of “tax shock,” you’re not alone.
That’s exactly where PAYG instalments come in. They help you spread your tax payments across the year, making cash flow more predictable and stress-free.
At Supertax, we simplify tax so you can focus on growing your business. This complete guide explains everything you need to know about PAYG instalments in Australia.
✅ Key Takeaways
- PAYG instalments spread your income tax across the year
- Different from PAYG withholding (employee tax)
- Applies to sole traders, investors, companies, and trust beneficiaries
- Triggered when your income and tax reach certain thresholds
- Two calculation methods: instalment amount or instalment rate
- Quarterly due dates: 28 Oct, 28 Feb, 28 Apr, 28 Jul
📌 What Are PAYG Instalments?
PAYG (Pay As You Go) instalments are advance payments toward your annual income tax.
Instead of paying one large amount at tax time, you prepay throughout the year.
🔍 PAYG Instalments vs PAYG Withholding
- PAYG Withholding: Tax you collect from employees and send to the ATO
- PAYG Instalments: Tax you pay on your own business or investment income
When you lodge your tax return:
- Instalments are credited
- You either pay the difference or receive a refund
🚀 When Do You Need to Start PAYG Instalments?
You can enter the system in two ways:
1. Automatic Entry by ATO
For individuals & sole traders:
- Instalment income ≥ $4,000
- Tax payable ≥ $1,000
- Estimated tax ≥ $500
For companies:
- Estimated tax ≥ $500
- OR income ≥ $2 million
2. Voluntary Entry
You can choose to start early if:
- Your business is growing
- You want better cash flow control
👉 Smart move: avoids spending money that belongs to the ATO.
💰 How PAYG Instalments Are Calculated
You’ll usually get two options:
Option 1: Instalment Amount (Fixed)
- Set by ATO
- Same amount each quarter
- Best for stable income
Option 2: Instalment Rate (Variable)
- Percentage of income
- Adjusts with earnings
- Ideal for seasonal businesses
👉 Example:
If your rate is 5% and income is $10,000 → Pay $500
