Getting the contractor vs employee classification wrong is one of the most expensive mistakes an Australian SME can make. The ATO, Fair Work, and state revenue offices all have different tests — and the penalties for misclassification include back-payment of super, PAYG withholding, payroll tax, leave entitlements, and fines up to $93,900 per contravention.
1. The Multi-Factor Test
Following the High Court decisions in CFMMEU v Personnel Contracting and ZG Operations v Jamsek (2022), the classification now focuses primarily on the written contract terms, not just how the relationship works in practice. Key factors include:
| Factor | Employee | Contractor |
|---|---|---|
| Control over work | Employer directs how, when, where | Worker controls method |
| Tools & equipment | Provided by employer | Worker provides own |
| Financial risk | None — paid regardless | Bears risk of profit/loss |
| Delegation | Must do work personally | Can delegate or subcontract |
| Basis of payment | Hourly/salary (time-based) | Per project/result |
| Insurance | Employer provides WorkCover | Worker has own insurance |
2. The Consequences of Getting It Wrong
- Super Guarantee Charge (SGC): Back-payment of super for the entire misclassified period, plus interest and an administration charge per employee per quarter.
- PAYG Withholding: You become liable for the tax that should have been withheld from wages — even if the worker paid their own tax.
- Fair Work penalties: Up to $93,900 per contravention for an individual, $469,500 for a company (2026 rates).
- Leave entitlements: Back-payment of annual leave, personal leave, and potentially long service leave.
- Payroll tax: State revenue offices can reassess contractor payments as wages and impose payroll tax plus penalties.
- WorkCover: Premium reassessment based on the reclassified wages.
3. High-Risk Industries
The ATO and Fair Work specifically target these industries for sham contracting:
- Building and construction — labour hire and subcontractor arrangements.
- IT and consulting — ABN contractors working on-site full-time for one client.
- Transport and delivery — owner-drivers who only work for one company.
- Cleaning — franchisee arrangements that look like employment.
- Hospitality — casual "contractors" without genuine independence.
- Beauty and fitness — chair renters and PT contractors at gyms.
4. How to Protect Your Business
- Get the contract right: Use a properly drafted independent contractor agreement that reflects the genuine nature of the relationship.
- Ensure genuine independence: The worker should control their own hours, use their own tools, and have the ability to work for other clients.
- ABN and insurance: Genuine contractors have their own ABN, public liability insurance, and professional indemnity cover.
- Invoicing: Contractors should invoice you (not be paid through payroll), and ideally not be paid hourly.
- Regular review: Even a legitimate contractor arrangement can drift into employment over time. Review annually.
Key Takeaways
- Classification is based on the written contract terms — get this right first.
- Misclassification penalties include back-super, PAYG, leave, payroll tax, and fines.
- High-risk industries: construction, IT, transport, cleaning, hospitality, beauty.
- Genuine contractors control their own work, provide their own tools, and bear financial risk.
- Review contractor arrangements annually — they can drift into employment over time.
