Tax deductions and accounting for carpenters.
Whether you're subcontracting to builders or running your own carpentry business, you can generally claim your tools, vehicle, licensing and safety gear against your income, as long as they relate to earning it and you keep the records to prove it. This guide covers what carpenters typically claim, how GST and TPAR work when you're subcontracting, and how we keep the books simple. We're Brisbane based and work with carpenters right across Australia.

What carpenters can claim.
The deductions that matter most in your trade, in rough order of value. Every one still has to pass the ATO's tests: you paid for it, it relates to earning your income, and you can show a record.
Power tools and hand tools
Nail guns, circular saws, drills, sanders and hand tools bought for carpentry work are generally deductible, either claimed outright or depreciated depending on the cost and the instant asset write-off rules current at the time - check the current threshold with us.
Work vehicle running costs
Your ute, including racking and toolbox fit-outs, is generally deductible for its business-use portion under the logbook or cents-per-kilometre method.
Tool insurance
Cover for theft or damage to tools carried in your vehicle or left on site is generally deductible - carpenters carry a lot of value in the back of the ute, so it's worth having and worth claiming.
Licences and trade tickets
Where your work requires a contractor licence or specific trade certification, the renewal fees are generally deductible.
White card and safety training
Your white card and any working at heights, scaffolding or other safety tickets required for site work are generally deductible.
Protective clothing and boots
Steel-cap boots, safety glasses and branded workwear are generally deductible. Plain jeans or shirts aren't, even if they only ever see a building site.
Public liability and income protection insurance
Premiums tied to your carpentry income, including public liability and income protection, are generally deductible.
Site consumables not reimbursed by the builder
Fixings, blades, sandpaper and similar consumables you supply yourself, rather than being provided by the head contractor, are generally deductible.
Mobile phone and job apps
The work-use portion of your phone, data and any job-tracking or timesheet apps is generally deductible.
Training and upskilling
Courses that build on your existing carpentry skills or keep a required licence current are generally deductible.
GST and BAS, without the headaches.
If you're subcontracting to builders, you'll usually invoice them GST inclusive once you're registered, and they'll claim the GST credit back. Keep an eye on retention amounts held back on bigger jobs - GST is generally payable on the full invoice value even before the retention is released, so it's worth planning your BAS cashflow around that.
Running your own carpentry business and supplying materials as well as labour works the same way as any other trade: GST on the full sale price including markup, GST credits on what you buy in. If you're mostly labour-only and subcontracting under someone else's job, your GST position is usually simpler.
Builders paying you as a subcontractor will almost certainly be including your payments in their Taxable Payments Annual Report, so keep your ABN and invoicing consistent - mismatches between what you declare and what's reported against your ABN are one of the easier things for the ATO to cross-check.
Sole trader, company or trust?
Plenty of carpenters work as sole traders, particularly if you're mostly subcontracting under a builder's insurance and licence rather than carrying head-contractor risk yourself. As you take on your own clients, employ other carpenters or start carrying real equipment and vehicle value, a company structure starts to make more sense for the cleaner separation of business and personal risk. It's a conversation worth having as your client mix shifts from subcontracting to running your own jobs.
Run the jobs, we run the numbers.
Job and timesheet apps like Tradify, ServiceM8 or NextMinute make it easy to track hours and materials against each job from your phone, and they connect straight into Xero so invoicing and job costing stay in sync. If you're mostly subcontracting, keeping clean records of hours and materials against each builder's job also makes it far easier to chase what you're owed.
Frequently asked questions.
Can I claim my ute if I'm a subcontractor?
Yes, generally in the same way as any other tradie: the business-use portion of running costs is deductible under the logbook or cents-per-kilometre method, regardless of whether you're working for one builder or many clients directly.
Do I need to register for GST as a subcontractor carpenter?
Once your turnover crosses the GST registration threshold you're required to, and a lot of subbies register earlier so they can claim GST credits on tools and the ute from day one. We'll help you work out where you actually sit.
Can I claim tools I bought before I started this job?
If you already owned tools and started using them for income-earning work, you can generally still claim depreciation on their remaining value based on when you started using them for that purpose. Bring us the details and we'll work out the right treatment.
Should I set up a company if I only subcontract to one builder?
Not necessarily - if your risk is largely covered under the head contractor's insurance and licence, sole trader is often perfectly sensible while you're in that position. It's worth revisiting once you start picking up your own direct clients or employing others.
What happens with the retention money builders hold back?
Retention is common on larger jobs and is usually released once defects liability periods pass. GST is generally still payable on the full invoiced amount when it's raised, so we help clients plan for that timing gap rather than being caught short on a BAS.
