Single Touch Payroll Setup Guide for Small Businesses (Australia 2026)
Complete STP Setup, Phase 2 Requirements & Compliance Checklist
๐จ Setting Up Payroll Incorrectly Can Cost You
Setting up payroll incorrectly is one of the fastest ways to create avoidable ATO problems.
If you are:
- Hiring staff for the first time
- Switching payroll software
- Fixing an existing payroll setup
๐ Then Single Touch Payroll (STP) setup is not just admin โ itโs compliance.
The good news?
Once your STP setup is done correctly, your payroll reporting becomes simple, accurate, and stress-free.
๐ Key Takeaways
โ๏ธ STP requires payroll data to be reported to the ATO every pay run
โ๏ธ Proper setup depends on software, employee data, and pay item mapping
โ๏ธ STP Phase 2 requires detailed payroll classification
โ๏ธ Most issues come from data errors, not software problems
โ๏ธ A clean setup saves time and prevents ATO penalties
๐ What Is Single Touch Payroll (STP)?
Single Touch Payroll is the ATOโs system for reporting payroll information in real time.
Instead of reporting annually, businesses must submit payroll data:
๐ Every time they process a pay run
๐ What STP Reports
STP submissions include:
- Employee details
- Gross wages
- PAYG withholding
- Superannuation contributions
Employees can also view their year-to-date income via ATO online services.
๐ฅ Who Must Use STP?
๐ If you employ staff in Australia, STP generally applies to you.
- Mandatory for large businesses since 1 July 2018
- Mandatory for small businesses since 1 July 2019
โ Common mistake:
Thinking small businesses are exempt โ they are not.
โ ๏ธ Why STP Setup Matters From Day One
STP errors donโt stay small.
๐ If your setup is wrong:
- Every pay run will carry errors
- Fixing it later becomes complex
- ATO discrepancies increase
Correct setup = long-term compliance + fewer issues
๐ Understanding STP Phase 2
STP Phase 2 introduced more detailed reporting requirements.
๐ What Changed in Phase 2
You now need to report:
- Disaggregated gross payments
- Allowances (specific categories)
- Overtime
- Income types (e.g. salary, closely held payees)
๐ก Why This Matters
Your payroll system must:
โ๏ธ Assign correct categories to each pay item
โ๏ธ Separate wages, allowances, and overtime
โ๏ธ Avoid generic or โmiscellaneousโ entries
๐ Incorrect mapping = incorrect reporting (even if totals look right)
๐ STP Reporting Requirements
| Requirement | Details |
|---|---|
| Reporting frequency | Every pay run |
| What to report | Wages, PAYG, super |
| Deadline | On or before payday |
| EOFY step | Finalise STP data |
๐ ๏ธ Complete STP Setup Process (Step-by-Step)
1. Verify Business Details
Before connecting to STP:
โ๏ธ ABN
โ๏ธ TFN
โ๏ธ Legal business name
โ๏ธ Address
๐ Must match ATO records exactly
2. Set Up Employee Records Properly
Each employee must have:
โ๏ธ Full legal name
โ๏ธ Address
โ๏ธ TFN
โ๏ธ Date of birth
โ Incorrect data = STP rejection
3. Choose the Right Payroll Software
Popular STP-compliant software includes:
- Xero
- MYOB
- QuickBooks
๐ The best choice depends on:
- Payroll complexity
- Business size
- Support availability
4. Connect Your Software to the ATO
This step involves:
โ๏ธ Registering for STP
โ๏ธ Authorising a declarer
โ๏ธ Linking via myGovID
๐ Important:
Only authorised users can lodge reports
5. Map Payroll Items Correctly (Critical Step)
This is where most businesses fail.
You must correctly map:
- Salary & wages
- Allowances
- Overtime
- Deductions
- Super
๐ Avoid:
โ Legacy pay items
โ Generic categories
โ Incorrect classifications
6. Enter Opening Balances (If Migrating)
If switching systems mid-year:
โ๏ธ Import year-to-date wages
โ๏ธ PAYG totals
โ๏ธ Super obligations
โ๏ธ Leave balances
๐ Incorrect balances = incorrect STP reporting
7. Run a Test Pay Run
Before going live:
โ๏ธ Process a dummy payroll
โ๏ธ Submit test STP report
โ๏ธ Fix any errors
๐ This step prevents real payroll issues
โ Real Example: Small Business Payroll
A small cafรฉ:
- 3 employees
- Weekly wages: $3,000
- PAYG withheld: $450
Process:
- Payroll processed in software
- Wages calculated
- PAYG applied
- STP report lodged before payday
- ATO receives updated data
๐ With correct setup, this becomes a repeatable weekly process
