Contractor vs Employee in Construction: Getting It Right

The contractor vs employee distinction is one of the most consequential compliance questions in Australian construction. Get it right, and you have a flexible, legitimate engagement with independent tradespeople. Get it wrong, and you're looking at PAYG liability, super guarantee exposure, Fair Work back-pay claims, and workers compensation liability — simultaneously.

The construction industry has long relied heavily on subcontractors — a model the ATO and Fair Work Ombudsman watch closely. Understanding the legal tests that distinguish genuine contractors from disguised employees is essential for every construction compliance business owner.

Why It Matters

If the ATO determines that someone you've been treating as a contractor is actually an employee, you become liable for:

• PAYG withholding — you should have been withholding tax from their payments and remitting it to the ATO. You now owe that tax (even if the worker has already reported their own income).
• Super guarantee — even if the worker is found to be an independent contractor, they may still be entitled to super (see below).
• Failure to withhold penalties — the ATO can impose penalties for unpaid PAYG withholding.

If Fair Work determines the arrangement was actually employment:

• The worker may be entitled to award rates — and if they were paid less, there's a back-pay claim
• They may be entitled to unpaid leave entitlements (annual leave, personal leave, long service leave)
• The engagement history may give them unfair dismissal protections

If the state workers compensation regulator determines the contractor was a deemed worker:

• Your insurance coverage may not have included them
• If they were injured, you may face uninsured liability

The Legal Test: Employee or Contractor?

The distinction between employee and contractor is determined by the true nature of the relationship — not just how it's labelled. In 2022, the High Court in CFMMEU v Personnel Contracting Pty Ltd and ZG Operations v Jamsek confirmed that the written contract is the starting point for analysis (where the contract is genuine and not a sham). However, conduct and subsequent facts are also relevant.

The key factors courts and the ATO consider:

Control

Employee: The business controls not just the result of the work, but how it's done — when to come in, how to perform the task, what tools to use.

Contractor: The business specifies a result (e.g., "frame out this house"), and the contractor determines how to achieve it, when to work, what methods to use.

In construction, the control test is nuanced — a site supervisor's authority to direct safety practices and site sequencing doesn't necessarily create an employment relationship, but day-to-day control over an individual worker's methods and hours does.

Integration with the Business

Employee: The worker is integrated into the business — they have a company email, they attend company meetings, they are part of the team.

Contractor: The worker operates independently — they provide a service to the business from outside.

Financial Risk

Employee: Bears no financial risk for the job — if a task takes longer than expected, the employee is paid for the extra time.

Contractor: Bears financial risk — if the job is quoted at a fixed price and takes longer than expected, the contractor absorbs the extra cost. Liable for defects in their own work.

Equipment

Employee: Uses tools and equipment provided by the employer.

Contractor: Typically provides their own tools and equipment.

Delegation

Employee: Must perform the work personally.

Contractor: Can subcontract or delegate the work to someone else.

Multiple Clients

Employee: Works exclusively (or primarily) for one business.

Contractor: Operates a genuine business and has multiple clients.

The Super Guarantee Exception

Even if a worker is a genuine independent contractor — not an employee — they may still be entitled to super guarantee contributions from you.

Under the Superannuation Guarantee (Administration) Act 1992, super is payable for a person who works under a contract that is wholly or principally for their labour, even if they operate under an ABN and are an independent contractor.

This catches many sole trader tradespeople in construction. If you engage a carpenter, plasterer, or tiler who:

• Is a sole trader
• Works primarily for you (even if not exclusively)
• Is engaged under a contract that is for their labour (not primarily for a result achieved using their own team)

...then you must pay them 12% super on their ordinary time earnings.

The ATO has published specific guidance on when the super guarantee applies to contractors. In construction, the safest approach is to pay super for sole traders unless you've sought specific advice confirming it doesn't apply.

The Taxable Payments Annual Report (TPAR)

Even when contractors are genuine independent contractors (not employees), construction businesses must report payments to them to the ATO via the Taxable Payments Annual Report (TPAR).

TPAR is due by 28 August each year and covers payments made to contractors who provided building and construction services during the financial year.

The report captures:

• Contractor's ABN
• Contractor's name and address
• Gross amount paid
• GST included in payments

The ATO uses TPAR data to cross-reference contractor income reporting. If a contractor doesn't report income that appears on a TPAR, the ATO notices.

Not lodging your TPAR is a compliance failure that the ATO actively monitors. If you use contractors in construction and haven't been lodging TPAR, this is an urgent gap to address.

The Role of Written Contracts

A written contract that correctly characterises the relationship provides important protection — but only if:

1. The contract is genuine (not a sham)
2. The actual conduct of the parties is consistent with the contract
3. The contract doesn't contain provisions that are inconsistent with independent contracting (e.g., prohibition on working for others, requirement to attend the principal's workplace at set hours, provision of all tools by the principal)

Standard elements of a genuine subcontractor agreement in construction include:

• Description of the work to be performed (scope/result-based, not hours-based)
• Fixed price or basis for payment (by project or by output, not hourly)
• Confirmation that the subcontractor provides their own tools and equipment
• Confirmation that the subcontractor carries their own insurance (and specifying minimum coverage)
• Subcontractor's right to engage others to perform the work
• Provisions for defect liability (the subcontractor is responsible for fixing their own defective work)
• No exclusivity clause

Red Flags in Common Construction Arrangements

Watch for these patterns that indicate what you're calling a contractor arrangement may actually be employment:

• The "subcontractor" only ever works for you, full-time, year-round
• You control their start and finish times, break times, and daily tasks
• You provide all tools, equipment, and materials
• They don't have their own ABN or their ABN is new and they don't operate as a real business
• They've never worked for any other client
• They couldn't tell you what their own hourly or daily rate is — they just receive what you pay them

What to Do If You're Not Sure

If you're uncertain about a specific engagement, the safest approaches are:

1. Use the ATO's online tools — the ATO has an employee vs contractor decision tool at ato.gov.au
2. Seek legal or tax advice — a brief review by a tax agent or employment lawyer is much cheaper than an ATO audit or FWO investigation
3. When in doubt, pay super — the cost of incorrectly not paying super is much higher than the cost of paying super you didn't strictly need to
