What is STP Phase 2 and do sole traders and small businesses really need to worry about it?
Yes, from 2026 STP Phase 2 brings stricter real-time reporting and extra data fields for employers with fewer than 20 staff. If you’re not set up correctly you risk penalties. The good news is Sole handles it all automatically.
You know that letter you don’t want to get?
The one from the ATO.
Yeah… that one.
Most sole traders don’t think about payroll rules until something forces them to.
Then suddenly you’re Googling at 10pm trying to figure out what you’ve missed.
That’s exactly what’s happening right now with stp phase 2 australia.
Heaps of small businesses think:
“I’ve only got 1–2 staff… this probably doesn’t apply to me.”
It does.
And ignoring it is where things go sideways.
What STP Phase 2 Actually Is (No Headache Version)
Let’s keep it simple.
STP (Single Touch Payroll) means:
Every time you pay your staff, you report it to the ATO.
STP Phase 2 just adds more detail to that reporting.
Same process.
More information.
That’s it.
So instead of just reporting:
- Total wages
- Tax withheld
You now report:
- Types of income
- Employee conditions
- More detailed breakdowns
That’s the shift with single touch payroll small business rules in 2026.
What’s Changed in STP Phase 2 (April 2026 Update)
Here’s what actually matters for you.
1. More Detailed Income Reporting
You now need to break down income into categories like:
- Salary and wages
- Overtime
- Bonuses and commissions
- Allowances
No more lumping everything together.
2. Allowance & Deduction Reporting
Things like:
- Travel allowances
- Tool allowances
- Uniform allowances
Need to be reported separately.
3. Employee Details Are More Specific
You may need to include:
- Employment basis (full-time, part-time, casual)
- Tax treatment details
- Income types (closer alignment with Services Australia)
4. Leave & Termination Data
If someone leaves or takes leave, more detailed info is required.
5. Closer Real-Time Compliance
The ATO now expects:
Accurate reporting every single pay run.
Not “we’ll fix it later”.
That’s the big shift with stp phase 2 sole trader setups.
Who This Affects (Yep… It’s You)
If you:
- Have employees (even 1)
- Pay wages
- Report through STP
Then this applies.
Doesn’t matter if you’ve got:
- 1 staff member
- 5 staff
- 10 staff
Small business = included.
That’s why stp phase 2 australia matters for sole traders hiring even a small team.
Deadlines You Need to Know
Let’s not sugar-coat it.
By 2026, all small employers are expected to be fully compliant with STP Phase 2 reporting.
If you’re still using:
- Old payroll systems
- Manual processes
- Or partial reporting
You’re exposed.
Don’t wait for the ATO to tell you.
Fix it now.
What You Now Need to Report (Quick Checklist)
Here’s the practical side.
Each pay run should now include:
- Gross earnings (broken down properly)
- PAYG withholding
- Super obligations
- Allowances (itemised)
- Employment type
- Leave and termination data (if applicable)
If your system isn’t handling this automatically…
That’s a red flag.
Real Risks If You Ignore This
Let’s be straight.
You Risk Penalties
Incorrect or incomplete reporting can trigger fines.
You Create ATO Issues
Errors build up over time.
Harder to fix later.
You Stress Yourself Out
Last-minute fixes are always worse.
You Lose Trust With Staff
Payroll mistakes affect real people.
That matters.
That’s why getting your single touch payroll small business setup right is non-negotiable now.
Don’t wait until you get a letter from the ATO. Get this sorted this week.
