Employee vs Contractor in Australia: The Test That Decides

Whether a worker is an employee or a contractor in Australia is decided by the real substance and practical reality of the whole working relationship — not by the label on the contract, and not by whether they have an ABN. Since 26 August 2024 the Fair Work Act has spelt that out in a "whole of relationship" test, and the ATO runs its own version of the same question for tax and super. Get it wrong and you're looking at back pay, super, penalties and possibly a sham contracting case, so here's how the test works and how to apply it to your own arrangements.

The test that decides

For most businesses, the Fair Work Act's definition of "employee" and "employer" (section 15AA) now requires you to work out the real substance, practical reality and true nature of the relationship. That means looking at the written contract and how the arrangement actually operates day to day: who decides how, when and where the work is done, who carries the commercial risk, and how independently the person really runs their own business.

This whole of relationship test started on 26 August 2024 as part of the Closing Loopholes reforms. It deliberately reversed two 2022 High Court decisions (Personnel Contracting and Jamsek) that had said a comprehensive written contract decided the matter on its own. Under the old approach, a well-drafted contractor agreement carried a lot of weight even if the person worked exactly like an employee. Under the new test, the paperwork is one factor among many.

One test for companies, another for sole traders

There's a wrinkle that matters for small businesses. Fair Work's guidance is that the whole of relationship test applies to "constitutionally covered" businesses — Pty Ltd companies and other incorporated entities. If you engage workers as a sole trader or partnership, the older "start of relationship" test, which puts more weight on the contract terms at the time you agreed them, still applies for Fair Work Act purposes.

Don't read that as a loophole. The ATO's tests for tax and super use the same kinds of indicators whatever your structure, courts have always been able to look past a contract that's a sham, and a contract that's partly verbal or has been varied by how you actually work will be judged on that conduct.

The factors that get weighed

No single factor decides it. Courts and the ATO look at the overall pattern.

Factor	Points towards employee	Points towards contractor
Control	You direct how, when and where the work is done	They decide how to achieve the result and largely set their own hours
Delegation	They must do the work personally	They can genuinely subcontract or send someone else
Tools and equipment	You supply most of it	They bring their own significant tools, vehicle or equipment
Commercial risk	You carry it; they're paid regardless of outcome	They bear the risk of loss, fix defects at their own cost, carry their own insurance
Payment	Hourly, weekly or salary, for time worked	Quoted price for a result, invoiced on completion or milestones
Exclusivity and integration	They work mainly or only for you, wear your uniform, use your email, look like part of your business	They advertise, have other clients, trade under their own business name
Expectation of ongoing work	Open-ended, regular, rostered	Engaged for a defined job or period

A tradie who quotes fixed prices, brings a van full of gear, works for six other builders and sends an apprentice when they're busy is a contractor. Someone who works 38 hours a week on your roster, on your equipment, under your supervision, invoicing you an hourly rate through an ABN they got because you told them to, is almost certainly an employee — whatever the contract says.

Why an ABN, an invoice or a signed agreement doesn't settle it

The most common misconception in small business is that if the worker has an ABN and sends invoices, they're a contractor. Not necessarily. An ABN is a tax registration anyone can get in minutes. It says nothing about control, risk or independence, which is what the test actually measures. The ATO says this plainly, and the Fair Work Ombudsman has litigated exactly this pattern.

The same goes for a "contractor agreement" that describes the person as an independent contractor. That description is evidence of what the parties intended, and a clear written agreement is still worth having (see our guide to the business contracts you actually need). But if the practical reality looks like employment, the label loses.

The ATO runs the same question for tax and super

The Fair Work test decides award coverage, leave, notice and unfair dismissal rights. The ATO decides PAYG withholding and superannuation, and it does so under its own ruling, TR 2023/4, issued in December 2023. The ATO's ruling leans more heavily on the contractual rights and obligations, in line with the High Court, but if the contract isn't fully in writing, has been varied by conduct, or is a sham, the actual arrangement comes back in. In practice the two tests point the same way for the great majority of small business arrangements.

What flows from the ATO classification:

Employees: you withhold PAYG from their wages, report through Single Touch Payroll and pay 12% super guarantee.
Genuine contractors: they handle their own tax. You don't withhold — unless they don't quote an ABN on their invoice, in which case you must withhold 47% of the payment unless they give you a written statement explaining why no ABN is needed.
Contractors who are employees for super only: see the next section.

There are also state-based rules. Most states' payroll tax laws deem payments under "relevant contracts" to be wages unless an exemption applies, and workers compensation schemes can treat a contractor as a "worker" for premium purposes. Both are assessed separately from the ATO and Fair Work tests, so check with your state revenue office and insurer.

When a contractor is still owed super

This one catches a lot of businesses. Under section 12(3) of the Superannuation Guarantee (Administration) Act, a person who works under a contract that is wholly or principally for their labour is treated as your employee for super purposes, even if they're a genuine contractor for every other purpose. TR 2023/4 confirms this reading.

You're typically caught when the contractor:

is paid mainly for their personal skills and effort rather than for materials or a result
can't delegate the work to someone else
contracts with you as an individual, not through their own company or trust

Think of a sole-trader bookkeeper on an hourly rate, a fitness instructor paid per class, or an IT consultant billing by the day. If they tick those boxes, you owe 12% super on the labour component of their invoices, and since 1 July 2026 you owe it within 7 business days of paying them under payday super. Where the contractor operates through their own Pty Ltd or trust, the super obligation sits with that entity, not you.

What misclassification actually costs

If a worker you've been treating as a contractor turns out to be an employee, you're liable for everything they should have received as an employee, and claims can go back six years. That typically means:

Minimum wages and award entitlements — the base rate under the relevant modern award, plus penalty rates, overtime, allowances and leave loading, less what you actually paid them
Leave — four weeks' annual leave and 10 days' personal leave a year under the National Employment Standards, plus long service leave under state law
Notice and redundancy pay if the relationship has ended
Super guarantee on all of it, plus the super guarantee charge on late payments (notional earnings compounding daily and an administrative uplift of up to 60%)
PAYG withholding you should have remitted, plus payroll tax and workers compensation premiums

On top of the back pay, underpaying employees is a civil contravention with its own penalties, and since 1 January 2025 intentional underpayment of wages or entitlements is a criminal offence carrying up to 10 years' imprisonment and fines of up to $1.82 million for an individual or $9.1 million for a company (as at September 2026). Small businesses with fewer than 15 employees that follow the Voluntary Small Business Wage Compliance Code won't be referred for criminal prosecution over honest mistakes — one more reason to classify workers deliberately rather than by default. The worker can also bring an unfair dismissal claim if you end the arrangement.

Sham contracting: the offence and the penalties

Sham contracting is treating an employee as a contractor to avoid employee entitlements. The Fair Work Act (sections 357 to 359) makes three things unlawful:

Misrepresenting an employment relationship as an independent contracting arrangement
Dismissing or threatening to dismiss an employee so you can re-engage them as a contractor doing the same work
Making a knowingly false statement to persuade an employee to become a contractor doing the same work

The defence used to be that you didn't know and weren't reckless. Since 27 February 2024, you must show you reasonably believed the person was a contractor. Courts must consider the size and nature of your business, and can consider whether you sought professional advice and followed it — so a written opinion from your accountant or lawyer is now worth real money.

Maximum civil penalties per contravention, at the $364 penalty unit (as at September 2026):

Who	Maximum penalty
Individual (including a sole trader, or a director involved in the breach)	$21,840 (60 penalty units)
Company with fewer than 15 employees	$109,200 (300 penalty units)
Company with 15 or more employees	$546,000 (1,500 penalty units) or three times the underpayment, whichever is greater

Higher maximums apply for serious contraventions. Each worker and each breach can count separately, and the back pay comes on top.

The high-income opt-out and unfair contract terms

Two related changes arrived with the new test on 26 August 2024:

A worker who earns above the contractor high income threshold — $190,100 for the year from 1 July 2026 — can give you a written opt-out notice so the start of relationship (contract-based) test applies instead. They can give only one notice per relationship and can withdraw it at any time. This is for well-paid specialists who want contractor status; it's not something you can impose.
Contractors earning below that threshold can ask the Fair Work Commission to vary or set aside unfair terms in a services contract made on or after 26 August 2024. If your contractor agreement is one-sided, it's now challengeable.

Decision checklist

Run each arrangement through these before you sign — and again once a year, because relationships drift.

Who controls the work? If you set the hours, the method and the supervision, lean employee.
Could they send someone else? If the answer is genuinely yes, lean contractor. If it's "technically, but they never would and we'd object", lean employee.
Whose gear? Significant tools, vehicles or equipment they own point to contractor.
Who wears the risk? Fixed quotes, fixing defects at their cost, their own insurance: contractor. Paid for time regardless of outcome: employee.
Do they have a real business? Other clients, their own branding, their own marketing. One client for two years on a roster isn't a business.
How are they paid? Hourly rates invoiced weekly look like wages. Quoted prices for results look like contracting.
Have you checked super separately? Even a genuine contractor may be owed super under section 12(3) if they're an individual paid mainly for labour who can't delegate.
Have you written it down? Get a proper agreement that matches reality, keep evidence of the factors above, and get written advice on any borderline case. Under the reasonable belief defence, that advice is your protection.

If most answers point to employee, hire them as one — our hiring your first employee checklist covers the registrations, the paperwork and the first pay run. Converting a long-running contractor to an employee is far cheaper than defending the alternative.

Key takeaways

Since 26 August 2024 the Fair Work test looks at the real substance and practical reality of the whole relationship; the contract is evidence, not the answer.
An ABN, invoices and a "contractor" label prove nothing on their own. Control, delegation, risk, tools and genuine independence are what count.
The ATO runs its own test for PAYG and super, and individual contractors paid mainly for their labour who can't delegate are still owed 12% super.
Misclassification means up to six years of back pay, leave, super and penalties, and misrepresenting employment is a sham contracting contravention with maximum penalties from $21,840 to $546,000 per breach (as at September 2026).
The defence is now "reasonable belief", so written professional advice on borderline cases is worth paying for.
Sole traders and partnerships fall under the older start of relationship test for Fair Work purposes, but the ATO and the courts still look at how the work is really done.
