Employee vs Contractor: What Every Small Business Needs to Know
Getting worker classification wrong can cost your business big time. Fines, penalties, back-payments and even reputational damage are all on the line if the ATO, your State Revenue Office (SRO), or your local WorkCover authority decides you’ve misclassified a worker.
With regulators now sharing more data and running detailed analytics, small businesses are under more scrutiny than ever. Getting it right upfront is essential.
ATO Contractor Rules 2025: Employee or Contractor?
The High Court has confirmed that the written contract is the starting point. If the contract is valid and not a sham, that’s what determines whether someone is legally an employee or a contractor.
That said, the ATO still looks at practical indicators, such as:
- Control: Do you decide how, when, and where the work is done?
- Delegation: Can the worker subcontract or must they do the job themselves?
- Payment: Are they paid hourly/daily (more like an employee) or for a result/project (more like a contractor)?
- Tools & expenses: Who supplies the equipment and covers costs? Contractors usually do this themselves.
What Are the Tax and Compliance Obligations?
PAYG Withholding
- Employees: Always applies.
- Contractors: Only applies if they don’t provide an ABN or there’s a voluntary withholding agreement.
- Risk: If you don’t withhold and report correctly, the ATO can deny your tax deduction.
Superannuation Guarantee (SG)
- Employees: Always applies.
- Contractors: May apply if they are sole traders working mainly for their own labour, can’t delegate, and are paid by time.
- Update: “Payday Super” begins 1 July 2026, requiring super to be paid at the same time as wages.
Payroll Tax
Each State Revenue Office has rules for contractors. Payments are generally taxable unless exemptions apply, such as:
- Services provided for fewer than 90 days in a financial year,
- The contractor uses their own staff,
- Work is incidental to supplying materials or equipment,
- The contractor also provides services to other businesses.
Workers’ Compensation
Rules differ across States, but many contractors can still be deemed employees. If most of the contract value is for labour and performed by one individual, the WorkCover authority may treat those payments as wages for workers’ comp.
Example 1: A Contractor Who Looks Like an Employee
You engage Sarah, a sole trader graphic designer. She:
- Works three days a week in your office,
- Uses your computer and software,
- Is paid $45 per hour,
- Cannot subcontract her work.
Even though Sarah has an ABN and invoices you, under the ATO’s Superannuation Guarantee rules she is effectively an employee.
- She is paid for her labour,
- She must do the work personally,
- She is paid by time worked.
Result: You may need to pay superannuation on top of her hourly rate.
Example 2: A Genuine Contractor
Now imagine you hire Michael, a builder, to refurbish part of your office. He:
- Provides his own tools, vehicles, and materials,
- Brings in his own subcontractors,
- Quotes a fixed price for the completed project,
- Works for multiple other clients.
Michael clearly operates as an independent contractor. You don’t need to pay superannuation, PAYG withholding, or workers’ comp for him. However, Payroll Tax may still apply depending on your State and the size of your payments.
Why Getting Worker Classification Wrong Is Costly
- Years of unpaid super with penalties of up to 200%
- Non-deductible wages if PAYG isn’t done correctly
- Surprise Payroll Tax bills from your State Revenue Office
- Higher workers’ comp premiums if WorkCover decides your contractor is really an employee
Small Business Checklist: What To Do
- Check your contracts – they must reflect reality.
- Review your contractors – especially sole traders or long-term contractors.
- Understand the rules – ATO, SRO, and WorkCover each apply different tests.
- Get advice early – prevention is far cheaper than remediation.
FAQs: Employee vs Contractor Australia
Do I need to pay superannuation for contractors?
Yes, sometimes. If the contractor is a sole trader working mainly for their labour, can’t delegate, and is paid by the hour or day, you may have to pay super — even if they have an ABN.
What if a contractor provides their own ABN?
An ABN alone doesn’t automatically make someone a contractor. The ATO and WorkCover will still assess the substance of the relationship.
Are contractor payments subject to Payroll Tax?
Yes, unless an exemption applies (e.g. under 90 days of work, or they use their own staff). Each State Revenue Office sets its own rules.
Who decides if a contractor is actually an employee?
- The ATO for PAYG and Superannuation Guarantee
- Your State Revenue Office for Payroll Tax
- The WorkCover authority in your State or Territory for workers’ compensation
What’s changing in 2026?
“Payday Super” will require employers to pay superannuation at the same time as wages from 1 July 2026.
Final Word
Just because someone has an ABN or calls themselves a “contractor” doesn’t mean your business is off the hook. The ATO, State Revenue Offices, and WorkCover authorities are all watching these arrangements closely, and the risks of non-compliance are rising.
