Yes, you can legally hire a sole trader as a contractor in Australia - but only if the arrangement is genuinely a contractor relationship.
The tricky part is that having an ABN, issuing invoices or signing a contractor agreement doesn't automatically make someone a contractor. If the way the work is set up looks more like employment, your business can still face sham contracting risks under the Fair Work Act 2009.
This doesn't have to stop you from using contractors. It just means you need to check the arrangement before the person starts, draft the contractor agreement properly, and make sure your day-to-day work practices match the contract.
Can You Hire A Sole Trader Without Sham Contracting?
Yes, you can hire a sole trader without sham contracting if the person is genuinely running their own business and you're engaging that business to provide services.
In Australia, sham contracting usually comes up where a business treats someone as an independent contractor when, legally, they're really an employee. The Fair Work Act prohibits things like:
- Representing an employment relationship as an independent contracting arrangement
- Dismissing, or threatening to dismiss, someone so you can re-engage them as a contractor to do substantially the same work
- Making false statements to persuade someone to become a contractor instead of an employee
A sole trader can absolutely be a real contractor. For example, you might hire a freelance designer to create your brand assets, a bookkeeper to manage monthly accounts, or a tradesperson to complete a defined job.
The risk rises when the person is treated like part of your team. If they're working regular hours set by you, using your systems and equipment, supervised closely, paid for time rather than results, and unable to work for others, the contractor label becomes harder to justify.
Since 26 August 2024, the Fair Work Act focuses on the real substance, practical reality and true nature of the working relationship for many employee versus contractor questions. So, your written agreement matters, but what actually happens after signing matters too.
How Do You Tell The Difference Between An Employee And A Contractor?
It depends on the whole relationship, but the main question is whether the person is working in your business or running their own business.
No single factor decides it. You need to look at the contract and the practical working arrangement together. Useful questions include:
- Control: Do you control how, when and where the work is done, or does the contractor decide how to deliver the service?
- Hours: Are they working a fixed roster, or are they engaged to complete tasks or projects?
- Payment: Are they paid hourly like staff, or do they quote fees, milestones or project rates?
- Delegation: Can they subcontract or send a suitably qualified replacement, or must they personally do all the work?
- Tools And Equipment: Do they bring their own equipment, software, vehicle or materials?
- Business Risk: Do they fix defective work at their own cost, carry insurance, and manage their own expenses?
- Independence: Do they advertise to the market and work for other clients?
- Integration: Are they presented as part of your staff, with a company email, uniform and internal title?
Say you run a cafe in Brisbane and engage Mia, a sole trader with an ABN, to cover three regular shifts every week as a barista. You set her roster, require her to wear your uniform, use your equipment, follow your manager's directions and stop her from working at nearby cafes. Even if Mia invoices you, that arrangement has strong employee features.
Compare that with engaging Mia's coffee training business to run a one-day staff training session for a fixed fee, using her own materials and methods. That looks much more like a contractor relationship.
What Should You Check Before You Offer The Work?
You should check the role, the person's business setup, the payment structure and your supervision model before you offer the work.
A simple pre-hire checklist can save you from trying to fix a risky arrangement later. Before you send the contract, work through these steps:
- Define The Outcome: Write down the deliverable or service you need, not just the hours you want covered.
- Check The ABN: Confirm the sole trader has a valid ABN and is contracting through their own business name if they use one.
- Ask About Other Clients: A contractor doesn't need dozens of clients, but exclusivity can increase employee-like risk.
- Decide Who Controls The Work: You can set deadlines and quality standards, but avoid managing every step like you would with an employee.
- Review Tools And Expenses: Check whether they'll supply their own equipment, software, transport or materials where practical.
- Consider Delegation: If personal service is essential, and they can't use a subcontractor, understand that this may make the relationship look more employee-like.
- Check Insurance: Ask for current public liability, professional indemnity or other industry-specific insurance if relevant.
- Plan Your Internal Setup: Avoid adding the contractor to staff rosters, performance review cycles or employee benefit programs unless there's a clear reason.
You don't need every contractor to tick every box. Some genuine contractors work closely with your team or use your systems for security reasons. The key is to understand the overall risk and make sure the structure matches the commercial reality.
If the checklist points heavily towards employment, it may be safer to get employee or contractor advice before hiring the person as a casual, part-time or full-time employee instead.
What Should A Contractor Agreement Include In Australia?
A contractor agreement should clearly describe an independent business-to-business arrangement, but it should also match how the work will actually be done.
Templates can be a helpful starting point, but they often miss details that matter for your industry, payment model and intellectual property. A lawyer should tailor the agreement before you use it, especially where the contractor will be working closely with your team or customers.
Contractor Agreement Outline
- Parties: Identify your business and the sole trader correctly, including ABN details.
- Services: Describe the specific work, deliverables, milestones and any exclusions.
- Term: State whether the engagement is project-based, ongoing or for a fixed period.
- Fees And Invoicing: Set out rates, GST treatment, invoice timing, payment dates and expense rules.
- Independence: Confirm the contractor controls how the services are performed, subject to reasonable business requirements.
- Delegation Or Subcontracting: Explain whether they can use others and what approval or quality controls apply.
- Equipment And Expenses: State who supplies tools, software, materials and insurance.
- Confidentiality: Protect your business information, customer lists, pricing, systems and trade secrets.
- Intellectual Property: Make sure your business owns, or has the right licence to use, the work product you're paying for.
- Policies And Compliance: List the safety, privacy, security or customer rules they must follow without turning them into employee policies.
- Termination: Set out notice periods, immediate termination rights and what happens to unfinished work.
- Dispute Process: Include a practical process for raising and resolving issues before they escalate.
Be careful with clauses that sound independent but don't reflect reality. For example, a clause saying the contractor can work for others won't help much if you require full-time availability and reject all outside work.
How Do Tax, Super And Insurance Affect The Risk?
Tax, super and insurance don't decide the employment question by themselves, but they can create extra exposure if the classification is wrong.
For tax, a contractor usually quotes an ABN and invoices your business. If they don't quote an ABN, you generally need to withhold tax at the no-ABN withholding rate, which is 47%, unless an exception applies. GST is also relevant if the contractor is registered for GST, usually because their turnover is at or above the $75,000 registration threshold.
Superannuation is often where businesses get caught. Even if someone is a contractor at general law, your business may still need to pay super guarantee if they're paid wholly or principally for their labour. From 1 July 2025, the super guarantee rate is 12%. Contributions are generally due quarterly, by 28 October, 28 January, 28 April and 28 July.
Let's go back to Mia. If you pay her $45 per hour for 30 hours a week over 10 weeks, that's $13,500. If super applies at 12%, the super component would be $1,620 for that period. If you haven't budgeted for it, the cost adds up quickly.
You should also check workers compensation and payroll tax rules in your state or territory. Some contractor payments can be included, depending on the arrangement and any exemptions. This is a good one to check with your accountant, because the rules can be technical and state-based.
Insurance matters too. If the sole trader doesn't carry the right cover and something goes wrong, your business may be left arguing about who is responsible.
What Happens If You Get Sham Contracting Wrong?
If you get sham contracting wrong, your business may need to back-pay employment entitlements and deal with penalties, tax, super and reputation issues.
The Fair Work Ombudsman can investigate sham contracting and underpayment concerns. Depending on the facts, practical consequences can include:
- Unpaid wages, overtime, penalty rates or allowances under a modern award or enterprise agreement
- Leave entitlements, notice of termination or redundancy pay if the person should have been treated as an employee
- Unpaid superannuation, plus charges and administration costs
- PAYG withholding and payroll tax issues
- Civil penalties under the Fair Work Act
- Disputes about ownership of intellectual property or confidential information if the contract is weak
For sham contracting contraventions, the current maximum penalties per contravention are $21,840 for an individual, $109,200 for a business with fewer than 15 employees, and $546,000 for a business with 15 or more employees. These figures are based on the Commonwealth penalty unit of $364 from 1 July 2026. Serious contraventions and other Fair Work Act breaches can attract higher penalties.
If you're worried about an existing arrangement, don't panic and don't simply terminate the contractor to make the issue go away. Start by:
- Collecting Records: Keep the contract, invoices, timesheets, rosters, emails, position descriptions and payment records.
- Reviewing The Reality: Compare the written agreement against how the work is actually performed.
- Checking Entitlements: Work out whether any award, super or tax obligations may have been missed.
- Fixing The Structure: Decide whether to move to an employment arrangement, change work practices, or update the contractor agreement.
- Getting Tailored Advice: Get help early if the person works regular hours, is critical to your operations, or has raised a concern.
Key Takeaways
- You can hire a sole trader as a contractor, but the arrangement needs to be genuinely independent.
- An ABN, invoices and a contractor agreement help, but they don't override the real substance of the working relationship.
- Check control, hours, payment, delegation, equipment, business risk and independence before the person starts.
- Your contractor agreement should match your work practices and deal clearly with fees, IP, confidentiality, insurance and termination.
- Super, tax, workers compensation and payroll tax can still be relevant even where someone is called a contractor.
- If the arrangement looks like employment, it's usually safer to fix it early than to wait for a dispute or regulator complaint.
