How does a solar business tell a subcontractor from an employee in Australia?

Why do so many solar businesses get subcontractor versus employee wrong?

Most solar businesses decide subcontractor versus employee by what the contract says or whether the installer already holds their own accreditation, not by how the job actually runs. The Fair Work Ombudsman and the ATO both look at the whole working arrangement in practice, and an installer with their own ABN and tools can still be found to be an employee.

The ATO says whoever hires the worker is responsible for getting the classification right for tax and super, and the details inside the actual working agreement decide the answer, not the invoice title, according to the ATO's guide to employees and contractors. The Fair Work Ombudsman makes the same point for building and construction, noting, “This is because they are self-employed and are covered by different laws, including the Independent Contractors Act 2006,” on its contractors in building and construction page. For a solar installer juggling panel supply and a network approval deadline, the question often waits until an audit forces it.

Why does this decision change the margin on every solar quote, not just the compliance risk?

For a solar installer, a quote blends panel and inverter cost, battery, certificates, network approval fees and the labour to get it all on the roof into one number. If that labour, a subcontractor's invoice or an employee's wage, is not costed into the job properly, the quote can look profitable and still leave nothing once the install is finished.

Choosing between an already-accredited subcontractor and training someone up as an employee is a cost decision, not only a legal one. A subcontractor's invoice usually carries its own margin built in, while an employee's wage needs super, workers compensation cover and training time added before the job reaches the roof. Either way, that cost has to sit against the right job in the business's numbers, or the gross profit on that install is a guess, and the guess tends to repeat on every system size the business sells.

What does the whole of relationship test look at on your crew?

You are expected, under the whole of relationship test the Fair Work Ombudsman uses, to look past what the contract calls someone and at how the work happens: who controls the install, who carries the financial risk, who supplies tools and roof access gear, whether the installer can send someone else to do the job, how hours are set, and whether the work is expected to continue indefinitely.

Since the twenty sixth of August, two thousand and twenty four, certain businesses must use this test, as the Fair Work Ombudsman's independent contractors page sets out, which says, “Whether a worker is a contractor or an employee depends on a number of factors.” It applies whether your crew is on a residential roof or a commercial solar fit out. Some state referred businesses use a different one, the start of relationship test, covered on the start of relationship test page; which one applies depends on the business and where it operates. None of these tests ask whether the installer holds their own accreditation to connect a system to the grid; being qualified and being a subcontractor are two separate questions.

What do super, workers compensation and ABNs mean for the installer on your roof?

You still need to work out super guarantee and insurance cover correctly even when an installer holds an ABN and invoices you, because an ABN on its own settles nothing. The rules also differ by state for workers compensation, so the same crew arrangement can land differently depending on where the job is done.

The ATO says, “Independent contractors who are paid mainly for their labour are eligible for super guarantee,” calculated on the labour part of the invoice, as set out on the ATO's super guarantee eligibility page. For workers compensation in New South Wales, icare's page on classifying workers or contractors points owners to the State Insurance Regulatory Authority's tool and is clear that “An ABN by itself is not a definite indicator of a person(s) status.” Other states and territories run their own schemes. The ATO also removes any guesswork for part of a solar crew, saying, “An employee works for you in your business, while an independent contractor is running their own business,” and that apprentices, trainees, labourers and trade assistants always sit on the employee side, as its guide to hiring a new worker sets out, which matters for a solar installer bringing on a first offsider for roof access and racking.

How do you make sure the install labour cost lands in the right place on your numbers?

You get a true picture of job margin when the labour cost, a subcontractor's invoice or an employee's wage plus super and cover, is tracked against each quote as the job runs, rather than lumped into overheads at the end of the month. That is what tells you whether the price quoted for a given system size actually held up once it was on the roof.

Picture a solar installer whose leads, quotes, job profit and incoming emails were spread across different inboxes, and whose quoting meant working out cable sizing and voltage drop by hand after every site visit. Classifying the crew correctly solves the compliance question, not the cost one, because the labour figure going into each quote was still carried over from the last job rather than what that job actually cost. What changed was moving to a business management system built around their own jobs: it tracks every lead through the pipeline, works out cable sizing and voltage drop at quoting stage, reports profit on each job automatically, turns incoming emails into tasks, and fills in a quote from photos taken on a site inspection.

This is where AI agents, software that does a job the way the owner would, with their own prices, wording and rules, earn a place in a solar business. One AI agent can match subcontractor invoices and wage data to the job they belong to as they come in, so margin on a battery install or a commercial solar fit out is known while the job is still live. A second AI agent can keep certificate and network approval paperwork moving so a warranty claim or a service call never waits on an admin step. Data first, this starts from the business's own job and pay data rather than memory of how the last few quotes felt.

Where can you check the current rules?

These are the official pages behind everything above, carrying the current factors, thresholds and forms the rule depends on, which this article does not repeat because they change. Check the one that matches the part of the question that matters for a given solar business.

• ATO: difference between employees and contractors: working out tax and super status, and the penalty risk of getting it wrong.
• Fair Work Ombudsman: independent contractors: the whole of relationship test and the factors it weighs.
• Fair Work Ombudsman: start of relationship test: the alternative test some state referred businesses must use.
• Fair Work Ombudsman: contractors in building and construction: how the test applies on site, and the myth a written contract settles it.
• icare NSW: classifying workers or contractors: the New South Wales approach to workers compensation status.
• ATO: hiring a new worker: why apprentices, trainees, labourers and trade assistants are always employees.
• ATO: super guarantee eligibility: whether a contractor paid mainly for their labour is still owed super guarantee.

How does Data First Coaching approach this?

Greg Allan's Data First Coaching starts from a solar business's own job data: what each install actually cost once labour, certificates and network approval fees are counted, and whether that matches what was quoted. For many owners the real question under subcontractor versus employee is one Greg puts plainly: “to get another trader that's got their solar ticket is going to be harder than finding someone that is willing to do the course,” which turns the classification question into a training and capacity decision as much as a compliance one. The Trade Business Intelligence looks at where that decision shows up in the numbers first, before anything else is worked through. The how, matching it to a solar business's own lead flow, crew and roof schedule, is worked through inside the Academy, with members, because the intelligence is powered by every member willing to share.
