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

What actually makes a subbie a subbie, not an employee, on a carpentry site?

The test is control, risk and who carries the gear, not whether someone has an ABN. According to the ATO, an employee's business has the legal right to direct how, where and when the work is done, while a contractor decides that for themselves, subject to reasonable direction, and wears the commercial risk if the job goes wrong.

On a framing job or a deck build this gets blurry fast. A chippy who rocks up with their own nail gun, their own ute and an ABN looks like a subbie, but that is only one factor among several. The ATO's own building and construction example notes a worker who is “integrated into the business; he is not operating independently of the business” looks like an employee, while one who “provides the equipment, tools and assets required to complete the work” looks like a contractor, see Building and construction. The Fair Work Ombudsman adds who supplies the tools, who can delegate the work to someone else, and whether the arrangement is expected to run on indefinitely.

Why does this trip up carpentry businesses specifically?

Because most carpentry businesses run a mix on the one site: day rate subbies on framing and fix-out, wages for apprentices and maybe a leading hand, and sometimes a whole chain of contractors on one renovation. Fair Work's own guide for the sector describes exactly this, a builder engaging a carpentry company as a contractor, that company engaging a subcontract carpenter, and the carpenter engaging an apprentice as an employee, see Contractors in building and construction.

Each link in that chain can be a different relationship. The apprentice is never a judgement call: the ATO is plain that “if you are working as an apprentice, labourer, or trainee you will always be an employee for tax and super purposes.” But the carpenter running the fit-out or hanging doors on day rate, or the subbie doing formwork before a pour, might sit on either side of the line depending on who directs the work, who can send a second person in their place, and who wears the cost if the skirting and architrave run has to be redone. There is also a structural wrinkle worth knowing: a business with 'Pty Ltd' or 'Ltd' in its name uses what the Fair Work Ombudsman calls the whole of relationship test, while sole traders, partnerships and some other structures in several states instead use an earlier, start of relationship test. Which test applies to a carpentry business depends on its own structure and state, so it is worth checking the current page rather than guessing.

What happens if a carpentry business gets this wrong?

Calling someone a contractor when the real relationship looks like an employee is sham contracting, and the Fair Work Ombudsman says it is illegal unless the business can show it reasonably believed the worker was genuinely a contractor. On top of that, the ATO treats a contractor paid mainly for their own labour as an employee for superannuation purposes, ABN or no ABN.

That matters on a carpentry site because so much of the work, hanging a door, running skirting and architrave through a fit-out, building a pergola, is paid for personal labour rather than a fixed result. If more than half the value of the contract is really for someone's hours on the tools, rather than a defined job they could hand to someone else, super may still be owed even though they invoice like a subbie. The ATO is clear that the business engaging the worker carries the responsibility to classify the relationship correctly, and an incorrect call can bring penalties. This is general information, not legal, tax or employment advice. Check your own situation with the body named here or a qualified adviser.

How do you keep your own job costing honest when you have both subbies and employees on the tools?

You keep it honest by booking day rate subbies and wages employees against the job the way they actually behave in your numbers, not by lumping all labour into one line. Once that split is right, your gross profit on a framing or fit-out job starts matching what actually lands in the bank, instead of looking fine on paper while the account tells a different story.

Picture a carpenter running two crews across framing, decks and fit-out work, paying some subbies a day rate and a couple of apprentices on wages. He could not get an honest cost of operations figure out of his own numbers. Every hour his crew spent driving between small jobs, picking up timber and hardware, or standing around waiting on a builder to finish a stage, was loading straight onto whatever job was running, so every job on the board looked barely profitable. When he stripped those non-billable hours out altogether the figure dropped so low it was clearly not believable either way. The real number sat somewhere in between, and memory was never going to find it.

This is where AI agents earn their keep. An AI agent is software that does a job the way the owner would, with their own prices, wording and rules, rather than a generic app built for every trade at once. In this carpenter's case, an AI agent pulled the actual wages and overhead straight from his live job and finance data and worked out his true cost of operations, with billable hours properly factored in. Overhead and non-billable time now sit in their own bucket instead of being spread thinly across every framing job, deck and fit-out, and the agent keeps that figure current as the next quote goes out. That is the data first habit: start from what the job and pay records actually show, not from a feeling about whether the quarter went well.

How do you know when to put someone on wages instead of a day rate?

You make that call from your own capacity and costing numbers, not from waiting until the bank balance feels safe enough. If your framing and fit-out pipeline is already full, and you are turning down renovation jobs or quoting them high because you do not trust you can staff them, that is a capacity problem a day rate subbie can only patch over for so long.

Plenty of carpenters start out subcontracting under someone else's ABN before they ever carry their own risk and reward. The shift into running your own jobs, with your own subbies and maybe your first apprentice or tradesperson on wages, is a different relationship again, and it should be driven by what your own numbers say about booked work and billable hours, not by gut feel. Once labour is engaged properly, whether that is formalising a subcontract arrangement or putting someone on wages, the hours an owner gets back to spend on quoting and growing the business are often the real payoff, not just staying on the right side of the rules.

Where can you check the current rules?

• Difference between employees and independent contractors, the ATO's own test for classifying a worker for tax and super.
• Employee or independent contractor - what's the difference, the six factors the ATO checks, including the rule for apprentices.
• Building and construction, worked examples from the building trades.
• Super for independent contractors, when super guarantee still applies to a contractor.
• Contractors in building and construction, Fair Work's guide to contractor chains on residential sites.
• I think I could be an employee not a contractor, the factors Fair Work weighs, and sham contracting.
• Independent contractor changes, the whole of relationship test and who it applies to.
• Independent contractors, which test applies to which business structure.

How does Data First Coaching approach this?

Data First Coaching starts from the carpenter's own job and pay data inside the Trade Business Intelligence, not from a checklist, to see where labour cost is actually sitting against each framing, deck or fit-out job, and whether a day rate subbie or a wages apprentice is quietly distorting the picture. Greg Allan built his own trade business before coaching others, and talks about the moment a carpenter moves from subcontracting under someone else's ABN to carrying their own risk and reward: “I was subcontracting for a mate of mine, probably for the first six months.” The how, the agents, the costing setup and the records behind it, is worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member who joins it open minded and willing to share.
