Contractor vs Employee Guide

Why the distinction matters

Whether a worker is an employee or an independent contractor changes almost everything about how you engage them: PAYG withholding, superannuation, leave entitlements, workers compensation, payroll tax, and their protections under the Fair Work Act. Getting it wrong isn't a paperwork problem — misclassification can leave you liable for years of unpaid entitlements, super guarantee charges and penalties, all at once.

The risk usually builds quietly. An arrangement that started as a genuine short-term contract drifts into something that looks, walks and works like employment. The label on the invoice doesn't protect you; what matters is the substance of the working relationship.

What actually decides the question

There is no single test. Courts, the ATO and the Fair Work Ombudsman look at the whole relationship, weighing factors such as:

• Control — who decides how, when and where the work is done? Employees are directed; contractors typically decide their own methods.
• Integration — is the worker part of your business (your uniform, your email, your roster) or running their own?
• Ability to delegate — a genuine contractor can usually subcontract or send someone else. An employee must do the work personally.
• Basis of payment — payment for a result or deliverable points to contracting; payment by the hour for time worked points more towards employment.
• Tools and equipment — contractors generally supply their own significant tools and bear the cost.
• Commercial risk — who wears the cost of rectifying defective work? Contractors carry risk (and usually their own insurance); employees don't.

The written contract matters, but it isn't the whole answer: the day-to-day reality of the relationship can override what's on paper, and the tests applied for tax purposes and for Fair Work purposes aren't identical — a worker can land differently under each. A contract can't turn an employment relationship into contracting if the way the work actually happens contradicts it, and sham contracting provisions specifically prohibit dressing up employment as contracting.

The traps that catch small businesses

• An ABN doesn't make someone a contractor. Anyone can get an ABN. It's a factor, not an answer.
• Super can still be payable to contractors. If you pay someone mainly for their labour, super guarantee obligations can apply even if they're a genuine contractor with an ABN. This is one of the most commonly missed obligations, and the ATO can look back years.
• Long-term "contractors" doing one client's work. Someone who has worked for you full-time for two years, uses your systems and takes direction from your managers is very hard to defend as a contractor, whatever the agreement says.
• Workers compensation and payroll tax have their own definitions. A worker can count as an employee for these purposes even when they're a contractor for tax purposes. Check the rules in your state.

How to review your current arrangements

Run every contractor on your books through a simple review:

• List everyone you pay on invoice and how long they've been engaged.
• For each, honestly assess the factors above — control, delegation, risk, integration.
• Check whether super guarantee applies to any labour-focused contracts, using the ATO's current guidance.
• Make sure written agreements exist and actually reflect how the work happens.
• Flag borderline cases for advice before they become long-tenured problems.

Where an arrangement doesn't hold up, converting the person to employment is almost always cheaper than defending a claim later.

Keep it reviewed, not just decided

Classification isn't a one-off decision — relationships drift, and the legal tests themselves have shifted more than once in recent years, so an assessment made a while ago may not hold today. Build a periodic check into your people processes (an annual review of all contractor arrangements is a reasonable cadence), and reassess whenever a contract is extended or the scope of work changes. If your back office doesn't have a natural home for this kind of recurring compliance work, that's a capability gap worth closing — see our people services and the back-office capability gap.

This is general information rather than legal advice — worker classification turns on the specifics of each relationship, so get professional advice on anything borderline. The ATO and the Fair Work Ombudsman both publish current decision tools worth using as a first pass.
