Single Touch Payroll Setup Guide for Small Businesses 

Complete STP Setup, Phase 2 Requirements & Compliance Checklist

 

🚨 Setting Up Payroll Incorrectly Can Cost You

Setting up payroll incorrectly is one of the fastest ways to create ATO compliance issues, penalties, and reporting errors.

If you are:

• Hiring staff for the first time
• Switching payroll software
• Fixing an existing payroll setup

👉 Then Single Touch Payroll (STP) setup is not just admin — it’s compliance.

💡 The good news?
Once set up correctly, your payroll becomes simple, accurate, and stress-free.

📌 Key Takeaways

✔️ STP requires payroll data to be reported to the ATO every pay run
✔️ Proper setup depends on software, employee data & pay item mapping
✔️ STP Phase 2 requires detailed payroll classification
✔️ Most issues come from data errors, not software
✔️ A clean setup prevents ATO penalties and saves time

📖 What Is Single Touch Payroll (STP)?

Single Touch Payroll (STP) is the ATO’s system for real-time payroll reporting.

👉 Instead of annual reporting, businesses must submit payroll data:
Every time they process a pay run

📊 What STP Reports

STP submissions include:

• Employee details
• Gross wages
• PAYG withholding
• Superannuation contributions

👉 Employees can also access their income via ATO online services.

👥 Who Must Use STP?

👉 If you employ staff in Australia — STP applies to you.

• Mandatory for large businesses since 1 July 2018
• Mandatory for small businesses since 1 July 2019

⚠️ Common mistake:
Thinking small businesses are exempt — they are not.

⚠️ Why STP Setup Matters From Day One

👉 If your setup is wrong:

• Errors repeat every pay run
• Fixing issues becomes complex
• ATO discrepancies increase

✔️ Correct setup = long-term compliance + fewer issues

🔄 Understanding STP Phase 2

STP Phase 2 introduced detailed payroll reporting requirements.

📌 What Changed

You must now report:

• Disaggregated gross payments
• Allowances (specific categories)
• Overtime
• Income types (salary, closely held payees)

💡 Why It Matters

✔️ Correct pay item classification is critical
✔️ Avoid generic or incorrect entries

👉 Incorrect mapping = incorrect reporting (even if totals look correct)
