Contractor vs Employee for Tradies: Getting the Classification Right

One of the most significant compliance risks facing small trade businesses is the misclassification of workers — treating employees as independent contractors when the law sees them as employees.

The consequences are substantial: PAYG withholding liability, super guarantee obligations, Fair Work back-pay claims, and workers compensation exposure. This isn't a theoretical risk — the ATO and Fair Work Ombudsman actively monitor the trades sector, where engaging workers under contracting arrangements is common.

This guide is specifically for trade business owners who want to understand whether their contracting arrangements are legally sound.

Why Trade Businesses Are at Risk

The trades sector has a long tradition of engaging workers as "subbies" — sole traders with ABNs, working for cash, driving their own van, and considering themselves self-employed. In many cases, this arrangement is genuine and legally sound.

But in other cases, what looks like a contracting arrangement is actually employment. The worker is told when to start, how to do the job, what uniform to wear, and which sites to attend. They don't work for anyone else. They don't bear any financial risk for the job — they just show up and get paid.

When the ATO or Fair Work audit these arrangements, the label "subcontractor" doesn't protect the engaging business. What matters is the substance of the relationship.

The Legal Test: Employee or Contractor?

The test for employment vs contracting in Australia has been refined by the courts over many years. The starting point is the written contract — if there is one that accurately reflects the arrangement. But the actual conduct of the parties is also relevant.

The key factors:

Control

The most important factor is control over how the work is done, not just what is produced.

Employee: You tell them how to do the job, what tools to use, when to arrive, and what to wear. You can direct them from task to task throughout the day.

Contractor: You specify a result — "install the electrical fit-out in apartment 14" — and they determine how to achieve it. You don't supervise their methods.

Red flag for tradies: If you're directing a "subcontractor" on a daily basis — telling them what tasks to do, in what order, using which methods — that looks a lot like employment.

Integration

Employee: The worker is part of your team — they're identifiable as a worker in your business, they attend your business premises, they represent your business to clients.

Contractor: The worker operates an independent business that provides services to yours. They may wear their own branding, have their own clients, and operate independently.

Financial Risk

Employee: Bears no financial risk — if the job takes longer, you pay for the extra time. They don't bear liability for defects.

Contractor: Bears financial risk — if the job costs more than quoted, that's their problem. They're liable for defective work at their own cost.

Tools and Equipment

Employee: Uses tools and equipment you provide.

Contractor: Uses their own tools and equipment. (Note: in construction, it's common for contractors to work with some materials supplied — this alone doesn't make them an employee.)

Ability to Delegate

Employee: Must perform the work personally.

Contractor: Can engage someone else to do the work. Can send a different worker for a different day.

Exclusivity

Employee: Works only (or primarily) for you.

Contractor: Has multiple clients and runs a real business.

The ATO's Specific Focus: Super Guarantee for Contractors

Even where a worker is a genuine independent contractor, they may still be entitled to super guarantee contributions from you.

Under the Superannuation Guarantee (Administration) Act 1992, the super guarantee applies to a person working under a contract that is wholly or principally for their labour, even if they have an ABN and are not an employee.

This is a critical point for trade businesses. If you engage a sole trader plumber, carpenter, or electrician, and the contract is substantially for their labour (not for a result delivered by their team using their own materials), you may be required to pay 12% super on what you pay them.

The test: Does the contractor provide their own labour? Are they paid principally for their personal work effort, not for the use of significant capital (like machinery) or a team of workers?

Practical implication: Most sole trader tradies you engage as subbies are likely to be covered by the super guarantee. The cost of incorrectly not paying super (SGC, interest, loss of deductibility) far exceeds the cost of just paying it.

The Taxable Payments Annual Report (TPAR)

Even genuine independent contractors don't exempt you from reporting obligations. If you make payments to contractors who provide building and construction services (which includes most trade services), you must lodge a Taxable Payments Annual Report (TPAR) with the ATO by 28 August each year.

The TPAR captures:

• Each contractor's ABN, name, and address
• Total gross amount paid to them during the year
• GST included in payments

Not lodging TPAR is a compliance failure that the ATO actively monitors. If you haven't been lodging TPAR for your trade contractors, address this immediately.

The Sham Contracting Prohibition

The Fair Work Act contains a specific prohibition on sham contracting — where an employer misrepresents an employment relationship as a contracting arrangement, or converts an employee into a contractor, specifically to avoid employment obligations.

Sham contracting penalties are significant — up to $18,780 per contravention for individuals and $93,900 per contravention for corporations (indexed figures as of 2025 — check current amounts).

Importantly, the prohibition covers not just intentional sham arrangements but also situations where the employer makes a misrepresentation that they ought not to have made. This means ignorance — "I didn't know they were really an employee" — is not a complete defence.

What to Do If Your Arrangements Are Unclear

1. Use the ATO's online tool — the employee/contractor decision tool at ato.gov.au is a useful starting point

2. Review your contracts — written contracts that accurately describe independent contractor arrangements provide important protection. If you don't have written contracts with subbies, get them.

3. Pay super for all sole trader subbies — unless you've received specific advice that super is not required, paying 12% super for sole trader contractors engaged primarily for their labour is the safest approach

4. Lodge TPAR annually — 28 August deadline for all payments to trade contractors

5. Seek advice — if you have a significant subcontract workforce and you're not sure about the classification, seek advice from a tax agent or employment lawyer before you get a call from the ATO
