You got the job. Then came the sentence: "Just grab an ABN and we'll pay your invoices — it's easier for both of us, and you'll take home more."

Maybe you're a barista. A delivery driver. A junior designer, a personal trainer, a labourer, a marketing coordinator. You're rostered, you're told when to turn up, you use their equipment, and you have one client — them. On paper, you're a business owner.

Sometimes that's a legitimate contracting arrangement. Often it isn't. Getting the ABN vs employee question wrong can cost you superannuation, leave, minimum pay rates and the right to challenge a dismissal — and since August 2024, the legal test for working out which one you are has changed in your favour.

What an ABN Actually Is (and Isn't)

An ABN — Australian Business Number — is a registration number for a business. It's free, it takes about fifteen minutes online, and getting one doesn't make you a business any more than buying a whistle makes you a referee.

That's the thing most people miss. Whether you're an employee or an independent contractor is not decided by whether you have an ABN, what the contract is titled, or whether you send invoices instead of receiving payslips. It's decided by what the working relationship actually looks like.

Which means a business can call you a contractor, have you sign a contractor agreement, pay you against invoices — and you can still be an employee at law, with every entitlement that comes with it.

The Test That Decides It: "Real Substance, Practical Reality"

Since 26 August 2024, the Fair Work Act has contained a definition of employment in section 15AA. It asks decision-makers to look at the real substance, practical reality and true nature of the working relationship.

Two words in there do most of the work: practical reality. The test looks at the whole of the relationship — the terms of the contract and how the contract is actually performed day to day. A well-drafted contractor agreement no longer settles the question on its own, which was closer to the position under earlier case law.

The factors that get weighed up include:

Control. Who decides how, when and where the work gets done? Being handed a roster and a uniform points one way. Quoting a job and doing it your own way points the other.

Financial risk. Do you stand to make a profit or a loss? A genuine contractor can lose money on a job. If you're paid an hourly rate with no exposure, you carry no business risk.

Tools and equipment. Whose gear are you using? Their coffee machine, their van, their laptop, their software licences — that's their business, not yours.

Ability to delegate. Could you send someone else to do the work in your place, and pay them? Genuine contractors usually can. Employees can't.

Hours. Are they set by you or by them?

Expectation of ongoing work. Is there a defined job with an end, or an open-ended expectation that you'll keep turning up?

No single factor decides it. But if you read that list and answered "them" to most of it, there's a real question about how you've been classified.

One exception worth knowing about

Individual contractors earning above the contractor high income threshold — set in line with the Fair Work high income threshold, which rose to $190,100 on 1 July 2026 — can give written notice to opt out of this test. That's aimed at genuine high-earning consultants, not someone being handed an ABN for a $28-an-hour job. If you did opt out, you can revoke it later, though you can't then opt out a second time.

What You Give Up on an ABN

"You'll take home more" is usually true of the gross figure and almost never true of the total. Here's what's on the other side of the ledger.

Superannuation. Contractors generally arrange their own. Important caveat: if your contract is wholly or principally for your labour, you're treated as an employee for super purposes and the business has to pay super for you anyway. A lot of ABN arrangements sit squarely in that category — and since payday super started on 1 July 2026, super has to reach the fund within 7 business days of payment, which makes a missing contribution much easier to spot.

Minimum pay rates and penalty rates. Employees are covered by the national minimum wage and, usually, a modern award with weekend, evening and public holiday rates. Contractors negotiate their own price and get none of that automatically. If you're on an ABN at a flat hourly rate for Sunday work, compare it to the award rate — our breakdown of the 1 July 2026 minimum wage increase is a useful starting point.

Paid leave. No annual leave, no personal or carer's leave, no paid public holidays. You don't work, you don't earn.

Notice and redundancy. A contract for services can often be ended with very little notice and no redundancy pay.

Unfair dismissal. Genuine contractors can't bring an unfair dismissal claim, because they were never dismissed — the contract just ended. If you're an employee, you may have that right once you've served the minimum employment period, which is where probation period rights come in.

Tax and insurance. No PAYG withheld, so the tax bill arrives as a lump. You may need to register for GST, and you're generally responsible for your own income protection. Workers compensation coverage for contractors varies by state and is not something to assume.

Add it up and the "extra" in your hourly rate frequently doesn't cover what's been shifted onto you.

Sham Contracting Is Illegal — and Enforcement Is Live

Sham contracting is where a business misrepresents an employment relationship as an independent contracting arrangement. It's prohibited under the Fair Work Act, and the employer can't simply say it made an honest mistake — it has to show its belief that the arrangement was genuine was reasonable.

It's also prohibited to dismiss, or threaten to dismiss, an employee in order to re-engage them as a contractor doing substantially the same work.

That's not theoretical. In March 2026 the Fair Work Ombudsman and the ATO announced penalties of nearly $200,000 against a Sydney health and wellness research company that did exactly that to three workers.

ATO Assistant Commissioner Tony Goding put it about as bluntly as a regulator can: "If you're treating workers like employees but calling them contractors, it may be illegal." Fair Work Ombudsman Anna Booth added that the regulator "won't hesitate to take enforcement action where we find unlawful activity in any sector."

Both agencies now use data matching to find these arrangements. If you're worried about raising it because it might blow up the job, know that the pattern is well and truly on their radar without you.

What to Do If You Think You're Misclassified

Keep the evidence of what the job actually looked like. Rosters, texts telling you when to start, uniform requirements, instructions on how to do the work, the fact that you had one client. Practical reality is the test — so collect the practical reality.

Work out what you'd have been paid as an employee. Identify the modern award that would cover your role, find the classification that matches your duties, and compare. The gap is often larger than people expect once penalty rates and leave loading are counted.

Get free advice before you confront anyone. The Fair Work Ombudsman can give guidance on classification and can investigate. The ATO handles the tax and super side. Most states also have a community legal centre or working women's centre that will talk it through with you at no cost.

Understand the timing. Underpayment claims and dismissal-related claims have time limits, and some are short — an unfair dismissal application generally has to be lodged within 21 days. It's worth asking about deadlines early rather than after you've finished gathering evidence.

One more thing: if you were pressured into the arrangement, that's relevant. So is the fact that you signed. Signing a contractor agreement doesn't waive employee entitlements you were legally owed — you can't contract out of the National Employment Standards.

Back to That "Just Grab an ABN"

Sometimes it's genuine. If you're quoting jobs, using your own gear, working for several clients and carrying real business risk, contracting can be the better deal — more control, more upside.

But if you're rostered, supervised, using their equipment and working only for them, the ABN isn't making you a business. It's moving super, leave, penalty rates, notice and tax off their books and onto yours. And the law changed in 2024 specifically to stop the paperwork from deciding that question.

Before you sign, it's worth asking one thing: if the practical reality of this job is employment, why does the contract say otherwise?
