Key takeaways
- Classify workers by how the relationship works in practice, not labels or ABNs.
- Check control, ability to delegate, tools, risk, integration, and how you pay.
- Use a simple workflow: decide status, sign the right agreement, collect documents, set up pay and super, review regularly.
- Strong records help you avoid sham contracting penalties and speed up ATO and Fair Work reviews.
What is sham contracting in Australia?
Sham contracting is illegal in Australia and occurs when an employer misrepresents an employment relationship as an independent contracting arrangement to avoid paying entitlements like superannuation, leave, and tax.
Sham contracting is a serious offence under Australian law, formally recognised as a contravention under the Fair Work Act 2009.
The Australian Taxation Office (ATO) and Fair Work Ombudsman both look at the real nature of the working relationship. If a worker is genuinely running their own business, they're a contractor. If they're integrated into your business and work under your direction, they're likely an employee, even if you've both signed a contractor agreement.
Why does this matter? Correctly classifying workers helps you avoid penalties, back-pay claims for wages and entitlements, superannuation guarantee charges, and reputational damage. The scale of contractor engagement is massive; in 2024–25, the Australian Taxation Office (ATO) tracked payments to over 1.4 million contractors, totalling over $507 billion, which creates significant opportunities for misclassification. For time-poor small business owners in trades, construction, and other high-risk industries, understanding sham contracting helps you stay compliant and protect your business.
Common patterns that signal potential sham contracting include:
- requiring fixed hours or a roster that mirrors employment
- directing how, when, and where work is done with close supervision
- preventing delegation or substitution of the work to others
- paying a flat rate that ignores award entitlements and overtime
- supplying all tools and carrying all business risk
If several of these apply to your working arrangements, it's time to review how you classify your workers.
Who is an employee vs contractor in Australia?
The contractor vs employee Australia test is a multi-factor assessment that weighs the whole relationship. Both the ATO and Fair Work use similar principles, though they focus on different obligations, tax and super for the ATO, and workplace rights and entitlements for Fair Work.
Here are the key factors to assess:
- Control: Who decides how, when, and where the work is done? Employees typically work set hours, follow your instructions, and work at your premises. Contractors usually control their own methods, schedule, and location.
- Delegation: Can the worker send someone else to do the job? Genuine contractors can usually subcontract or substitute their work. Employees must do the work personally.
- Tools and expenses: Who provides the equipment, materials, and pays for business costs? Contractors usually supply their own tools and absorb costs. Employees use your tools, and you cover expenses.
- Risk and profit: Does the worker share commercial risk and have a genuine chance to profit or lose? Contractors quote for results, manage their own costs, and can make or lose money. Employees get paid for time, with no financial risk.
- Integration: Is the worker part of your business or running their own? Employees are integrated into your structure, wear your uniform, use your branding, and are seen as part of your team. Contractors operate independently, often under their own business name.
- Payment: How do you pay them? Employees are paid for time – hourly, weekly, or salary – with tax withheld. Contractors invoice for results or milestones, usually with an ABN and GST.
Quick clarifications to avoid misclassifying employees and contractors in Australia:
- An ABN and invoices do not decide the status. Many genuine employees are incorrectly told to get an ABN.
- Some contractors get super if the contract is mainly for labour (the ATO sham contracting guidance covers this).
- Fair Work rules and ATO tests align in principle but cover different obligations—workplace entitlements vs tax and super.
The label you use doesn't matter. What matters is the substance of the relationship. If you're unsure, the ATO's employee or independent contractor guidance can help, or speak to your accountant or bookkeeper.
What are the signs of sham contracting?
The following are warning signs, not definitive proof. But if several appear in your working arrangements, it's worth reviewing the classification early.
Common red flags to check:
- fixed shifts, uniforms, and tight supervision on 'contractor' roles
- no right to delegate — personal performance required
- hourly pay with no genuine chance of profit or loss
- work methods directed by the business, with all tools and materials supplied
- long, regular roster running over many months
- flat hourly rate that undercuts award conditions
- workers pushed to get an ABN to start work quickly
If you recognise several of these patterns, review your arrangements as soon as you can. The building and construction industry is heavily scrutinised for sham contracting, with around 20% of the 7,000-plus tip-offs received by the ATO in 2024–25 including allegations of the practice.
Similarly, the road freight industry is under scrutiny, with nearly 25% of over 800 tip-offs received by the ATO in 2024–25 referring to sham contracting. Early action to reclassify workers and fix your processes will reduce your risk and protect your business.
The following guides can help you make informed decisions and provide practical guidance on how to hire an independent contractor correctly, or to understand the benefits of independent contracting.
How do you avoid sham contracting?
A clear, repeatable process helps you classify correctly and keep clean records. The steps below will guide you through setting up compliant engagements and maintaining the right evidence.
1. Decide the working status
Weigh the factors – control, delegation, tools, risk, integration, payment – against ATO’s sham contracting guidance. Note your reasons in writing. If you're unsure, get advice from your accountant or an employment lawyer.
2. Choose the right agreement
Use an employment agreement for employees or an independent contractor agreement for contractors. The contractor agreement should set scope, deliverables, delegation rights, insurance requirements, and tax obligations. Avoid generic templates by tailoring the agreement to the actual work.
3. Collect worker details
For employees, get tax file number, superannuation details, and right to work checks. For contractors, collect ABN, right to work, licences, insurance certificates, and signed terms. Keep copies on file.
4. Set up pay and tax
Add employees to payroll with correct tax withholding and award rates. Set up contractors as suppliers in your accounting system with the right invoicing and GST settings. Make sure your software handles both correctly so you don't have to manage these obligations manually.
5. Assess super
Pay superannuation guarantee to employees. For contractors, assess whether the contract is wholly or principally for labour. If so, you may need to pay super. The ATO's super for contractors guidance explains when this applies.
6. Pay and report
Run payroll on schedule for employees, lodge required reports (like Single Touch Payroll), and keep GST and PAYG withholding current. For contractors, pay invoices on agreed terms and keep records of all payments.
7. Review regularly
If control, delegation, or risk shifts over time, reassess the status and update documents. A contractor who becomes embedded in your business may need to be reclassified as an employee.
Keep the right evidence and records
Tidy records reduce risk and speed up reviews if the ATO or Fair Work come knocking. Store and keep current:
- Signed agreements and clear role or scope descriptions
- ABN checks, insurance certificates, licences, and right to work results
- Timesheets, invoices, and payment proofs
- Super assessments for contractors and any contributions made
- Notes from periodic status reviews and any changes made
Good accounting software makes this easier. You can store documents, track payments, and generate reports that show how you've classified and paid workers. This audit trail is invaluable if you ever need to prove compliance.
Here is a tip for accountants and bookkeepers: Standardise the workflow across clients. Package onboarding and periodic reviews into your service offering. Use templates for agreements, checklists for worker setup, and a single system to centralise records. This reduces risk for your clients and positions you as a trusted advisor on compliance.

What are sham contracting penalties and risks?
Getting the status wrong can trigger serious consequences. Here's what you could face if you're found to have engaged in sham contracting:
Pay civil penalties under the Fair Work Act per contravention
The financial penalties for sham contracting can be severe, with courts able to impose fines for larger businesses of up to $495,000 or three times the underpayment amount per contravention. Penalties increase for serious or repeated breaches.
Reimburse underpayments
You may have to back-pay wages, leave entitlements, allowances, and other employee benefits dating back years. This can add up quickly, especially if multiple workers are affected.
Pay superannuation guarantee charge plus interest and penalties
If you should have paid super but didn't, the ATO will issue a superannuation guarantee charge. Beyond direct fines, businesses may also be liable for unpaid superannuation contributions, attracting additional penalties of up to 200% of the superannuation guarantee charge.
Fix pay as you go (PAYG) withholding and payroll tax issues, with interest
You may owe back taxes, payroll tax, and interest if you didn't withhold and remit correctly. State revenue offices can also pursue payroll tax for misclassified workers.
Manage audits and public compliance actions
The ATO and Fair Work can audit your business, require extensive documentation, and publish details of non-compliance. This damages your reputation and can affect your ability to win new work or retain clients.
What is the defence to sham contracting?
The 'reasonable belief' defence is the primary legal protection available to employers who misclassify a worker unintentionally. Under the Fair Work Act 2009, an employer has not contravened the sham contracting provisions if, at the time of the misrepresentation, they reasonably believed the arrangement was a genuine contract for services rather than employment.
Whether your belief was reasonable depends on several factors: the size and nature of your business, whether you sought legal or professional advice before engaging the worker, how closely the arrangement resembled genuine contracting in practice, and whether you applied a consistent classification process across your workforce.
This defence is not a blanket shield. If the working relationship clearly resembles employment and you made no effort to assess the correct status, a court is unlikely to accept that your belief was reasonable.
The stronger your documentation and classification process, the more credible your position becomes if a dispute arises.
What are regulators focusing on now?
Regulators are targeting industries and patterns that suggest deliberate or systemic misclassification. Construction, building, cleaning, transport, and gig economy platforms are under close scrutiny.
The authorities are actively pursuing and penalising companies for this behaviour, as seen in one case where the Fair Work Ombudsman secured nearly $200,000 in penalties against a company that unlawfully re-engaged employees as contractors.
If you operate in these sectors, proactive reviews and strong records are essential to reduce disruption and demonstrate good faith.

FAQs on sham contracting
Here are answers to common questions about sham contracting in Australia.
Is sham contracting a criminal offence?
Sham contracting is a civil matter, not a criminal offence, under the Fair Work Act 2009. Courts can impose significant financial penalties on businesses and individuals found to have misclassified workers, but there is no risk of criminal prosecution.
Do contractors get superannuation in Australia?
Yes, you must pay superannuation guarantee for some contractors if the contract is wholly or mainly for their labour, even if they have an ABN and invoice you. You can use the Australian Taxation Office (ATO) super for contractors guidance to check whether super applies to a particular arrangement.
Does an ABN prove someone is a contractor?
No, an ABN on its own does not prove someone is a contractor, because it is just a tax registration number. The working relationship, including control, delegation, tools, risk, integration, and how you pay them, determines whether they are an employee or a contractor.
Can I convert a contractor to an employee later?
Yes, you can convert a contractor to an employee if their role changes. They will become more integrated into your business, but you should update their agreement, move them to payroll, and start paying super and entitlements from that point. It is better to reclassify proactively than wait for a dispute or audit.
Where can I report or get help about sham contracting?
If you're a business owner who needs help, speak to your accountant, bookkeeper, or an employment lawyer, and use resources such as the Australian Taxation Office (ATO) employee or contractor decision tool and Fair Work Ombudsman guidance. These resources explain how to classify workers correctly and what to do if you think past arrangements may be wrong.
