Accounting for Trades Businesses in Brisbane
A trades accountant for a Brisbane business is a CA or CPA-qualified accountant with specific experience in building, construction, plumbing, electrical, landscaping, and related trades. They understand the ATO’s rules around contractors and employees, the Taxable Payments Annual Report (TPAR), job-cost accounting, cashflow management on project-based work, and the right business structure for tradespeople at different stages of growth.
In short: Most tradies are either overpaying tax, underprotecting their assets, or running their books in a way that makes growth harder than it needs to be. The right accountant fixes all three.
Why trades businesses have unique accounting needs
Running a trades business is nothing like running a retail shop or a professional services firm. Revenue is uneven: large invoices paid late, retentions held by head contractors, seasonal slowdowns, and the constant juggle of materials costs, subcontractor payments, and equipment depreciation all happening at once.
The ATO also pays close attention to the building and construction industry. Contractor arrangements, trust distributions, and unpaid superannuation for workers classified as employees are all active areas of compliance risk. A generalist accountant who files your BAS and does your tax return is not going to cut it.
The specific challenges trades businesses face
- Cashflow gaps. Progress billing, slow-paying clients, and retentions can leave a profitable business chronically short of cash.
- Tax timing. PAYG instalments due quarterly, BAS obligations every quarter or month, and end-of-year income tax, all hitting at different times.
- Contractor vs employee risk. The ATO’s rules for classifying workers are strict. Misclassifying employees as contractors can trigger back-payment of super, PAYG withholding, and penalties.
- TPAR obligations. Businesses in building and construction that pay contractors must lodge a Taxable Payments Annual Report by 28 August each year. Many trades operators don’t know this applies to them.
- Job costing. Without accurate per-job costing, profitable and unprofitable jobs look the same until the end of the year, by which point nothing can be done about it.
- Depreciation and asset management. Tools, trailers, vehicles, and plant equipment each have different depreciation rules. The instant asset write-off is now permanently set at $20,000 for eligible small businesses (turnover under $10 million) from 1 July 2026.
ATO focus area: Building and construction is consistently one of the ATO’s highest-focus industries for compliance activity. Contractor payments, unreported cash, trust distributions, and unpaid superannuation are all active audit targets.
Tax for Tradespeople: What You Can and Can't Claim
Trades businesses can claim a wide range of legitimate tax deductions, but only for expenses directly related to earning business income. Here is a practical breakdown.
What Tradies Can Typically Claim
- Tools and equipment hand tools, power tools, measuring equipment (full deduction or depreciation depending on cost and thresholds)
- Vehicle costs fuel, servicing, registration, insurance, and depreciation on a ute, van, or work vehicle used for business
- Protective clothing and workwear hi-vis gear, steel-cap boots, safety glasses, helmets
- Licences and trade memberships contractor licences, industry body memberships, first aid certificates
- Training and upskilling trade-related courses, safety training, apprenticeship supervision costs
- Home office or site office if you run admin from home, a portion of phone, internet, and home running costs may be deductible
- Subcontractor costs payments to subcontractors are deductible and must be reported in your TPAR
- Marketing and quoting software websites, quoting apps, job management platforms
- Accounting and professional fees your accountant’s fees are fully deductible
- $1,000 instant tax deduction, from the 2026–27 income year, eligible sole traders earning income from work can claim an automatic $1,000 deduction without itemising receipts. If your total work-related expenses are under $1,000, you do not need to keep or submit receipts. If they exceed $1,000, claim the higher amount using normal substantiation rules.
Common Claims That Get Disallowed
- Personal vehicle use. If your ute is also used for personal trips, only the business-use proportion is deductible. A logbook is the ATO’s preferred method of substantiation.
- Ordinary clothing. Regular clothes, even black jeans worn on a worksite, are not deductible unless they carry a distinctive logo or are protective equipment.
- Fines and penalties. Traffic fines, safety breaches, and ATO late-lodgement penalties are not deductible.
- Private meals and entertainment. Client entertainment has very limited deductibility and is subject to Fringe Benefits Tax. Ask before claiming.
Instant asset write-off: Eligible small businesses with turnover under $10 million can deduct the full cost of qualifying assets up to $20,000 in the year of purchase, rather than depreciating them over time. The Government permanently extended this $20,000 threshold from 1 July 2026. Confirm your eligibility and whether the asset qualifies with your accountant before a major purchase.
Business Structure for Tradies
Sole trader, company, or trust?
Most tradespeople start as sole traders. It’s the simplest and cheapest way to operate. But staying as a sole trader too long is one of the most common and costly structuring mistakes in the trades industry.
Sole trader: When it works
A sole trader structure makes sense for a tradie who is starting out, working solo or with minimal subcontractors, earning under $80,000 to $100,000 in profit, and working in a lower-risk trade where personal liability exposure is limited.
Tax example: A sole trader earning $120,000 in profit pays approximately $28,732 in income tax (24%) under 2026–27 rates. The same income retained in a company is taxed at $30,000 (25%). At this income level the difference is modest, but it grows significantly as income rises.
Note: The lowest marginal tax rate dropped from 16% to 15% on 1 July 2026 and drops again to 14% on 1 July 2027. These figures reflect 2026–27 rates. Ask your accountant for a calculation based on your specific circumstances and the current year’s rates.
Company (Pty Ltd): When to make the switch
A company structure is worth considering when:
- Profit consistently exceeds $100,000 to $120,000 per year
- You employ staff or use subcontractors regularly
- You work on larger commercial or government contracts that carry significant liability
- You want to bring in a business partner or eventually sell the business
- You are accumulating equipment, vehicles, or other assets worth protecting
- From the start if you’re planning to grow your business
The company tax rate of 25% (base rate entities) versus the personal top marginal rate of 47% is a real, compounding tax advantage as income grows. Profits retained in the company can be reinvested into equipment, staff, or growth before any personal tax is paid.
Trust: For established trades businesses with family or assets
A discretionary trust gives a trades business owner flexibility for income distribution and asset protection. If you have a spouse or adult children with lower incomes, distributing trust income to them can reduce the family’s overall tax bill; subject to the important Budget change noted below.
Trusts are more complex to set up and administer. They are best suited to established business owners with a clear picture of their income who are thinking about longer-term wealth and succession planning.
2026–27 Budget — Important change to discretionary trusts:
- From 1 July 2028, the Government has proposed a 30% minimum tax on the taxable income of discretionary trusts. The tax is paid by the trustee. This will limit the benefit of distributing to lower-income family members, because the trust itself will face a 30% floor regardless of the beneficiary’s personal tax rate.
- The Government has also confirmed expanded rollover relief for three years from 1 July 2027, allowing businesses to restructure out of a discretionary trust into a company or fixed trust. This window is time limited.
- If you currently operate through a discretionary trust, or are considering one, speak to your accountant before acting. The best time to review your structure is before 1 July 2027 when the rollover relief window opens.
Cashflow Management for Trades Businesses
Cashflow is the number one stress point for most trades business owners. A job can be profitable on paper while the business is struggling to make payroll. The gap between completing work and getting paid, made worse by retentions, slow clients, and quarterly BAS bills, is where most trades businesses run into trouble.
The main cashflow challenges in trades
- Retentions. Head contractors commonly hold 5 to 10% of each progress claim as a retention until project completion or the end of a defects liability period. These need to be tracked and followed up systematically. They represent real money that many business owners under-pursue.
- BAS timing. A quarterly BAS bill of $15,000 to $30,000 can feel like a shock if cash has not been set aside progressively. Set aside GST collected from clients into a separate account each week.
- Materials float. Paying for materials before invoicing or receiving payment from clients is a standard cash gap in trades. Progress billing, invoicing at project milestones rather than on completion, is the most effective way to reduce this gap.
- Slow-paying clients. Residential clients and small builders are the slowest payers. Clear payment terms, early payment incentives, and following up invoices on day 30 rather than day 60 all make a measurable difference.
- Superannuation. From 1 July 2026, super must be paid each pay run under the Payday Super rules, not quarterly. Deferring payment triggers the Superannuation Guarantee Charge, adding a non-deductible penalty on top of the unpaid super. This is now a per-payroll compliance obligation, not a quarterly one.
Practical cashflow tools for tradies
- Xero cashflow forecasting a forward view of inflows and outflows by week
- Separate bank accounts for GST/BAS, super, and tax ringfence what is not yours
- Progress billing clauses in all contracts never bill only on completion
- A business credit facility or overdraft not to fund losses, but to smooth the gap between outgoings and incoming payments
TPAR: What it is and which tradies need to lodge it?
Who must lodge a TPAR?
Your business must lodge a TPAR if it:
- Provides building and construction services, including plumbing, electrical, carpentry, painting, concreting, roofing, tiling, and related trades
- Pays contractors for those services, whether individuals, companies, or trusts
- Earns any income from building and construction services. There is no minimum threshold
TPAR also applies to cleaning, courier, road freight, IT, and security services. If your trades business does any work in these categories, check with your accountant.
TPAR lodgement details
- Due date: 28 August each year, covering the previous financial year (1 July to 30 June)
- How to lodge: through the ATO Business Portal, your accounting software (Xero, MYOB), or via your tax agent
- What to report: ABN, name, address, total gross amount paid, and total GST paid for each contractor
Penalty for failure to lodge: up to $1,375 per quarter depending on business size
Common TPAR mistake: Many trades businesses assume TPAR only applies if they are a head contractor. It applies to any business that pays contractors for building and construction services . This includes subbies paying subbies.
Generalist Accountant vs Trades-specialist Accountant
Not all accountants are the same fit for a trades business. Here is what the difference looks like in practice.
| Generic accountant | Trades-specialist accountant | |
|---|---|---|
| Tax knowledge | General tax compliance | ATO contractor rules, STP, apprentice incentives |
| Software | Standard Xero setup | Xero + job-costing, quoting, field apps (ServiceM8, Tradify, etc.) |
| Cashflow advice | Reactive, end-of-year | Proactive: retentions, progress billing, WIP management |
| Structure advice | Basic entity setup | Trades-specific: trust vs company vs sole trader |
| ATO risk awareness | General compliance | Sham contracting, TPAR, Division 7A for operators |
| Benchmarking | Against general SMEs | Against trades and construction industry peers |
| BAS support | Quarterly filing | Cashflow-timed lodgement, fuel tax credits |
End-of-year accounting checklist for trades businesses
Use this checklist with your accountant before 30 June each year.
- Reconcile all bank accounts and credit cards to 30 June
- Confirm all outstanding invoices and retentions are recorded as income Retentions not yet received are generally assessable when earned, not when paid.
- Review and record all subcontractor payments for TPAR lodgement Due 28 August. Confirm ABNs, addresses, and total amounts paid.
- Review vehicle logbooks to confirm business vs personal use is documented ATO requires a 12-week logbook for the logbook method, and odometer readings for cents-per-km.
- Confirm all employee superannuation is paid each pay run and is current to date. Payday Super rules apply from 1 July 2026, super must be paid with each salary payment, not quarterly. The ATO’s quarterly due dates (28 July, 28 October, 28 January, 28 April) no longer reflect the required payment frequency.
- Review plant and equipment for instant asset write-off opportunities. The threshold is permanently $20,000 for eligible businesses with turnover under $10 million (from 1 July 2026). Confirm eligibility with your accountant.
- Stocktake materials and consumables on hand at 30 June
- Review WIP (work in progress) to ensure partially complete jobs are accounted for correctly WIP accounting affects your taxable income. The method you use must be consistent.
- Review your business structure to check it still suits your income and risk profile
- Book a pre-year-end review with your accountant, ideally in May Most tax planning opportunities close on 30 June. Decisions made in July are too late.
Frequently asked questions
Common questions from Brisbane tradies and construction business owners.
Do tradies need a separate business bank account?
Yes. Mixing personal and business finances is one of the most common and costly mistakes tradespeople make. A separate business account makes BAS preparation faster, simplifies tax time, and gives you a clearer picture of actual business cashflow. Most trades accountants will insist on it from day one.
Should a tradie operate as a sole trader or company?
Most tradespeople start as sole traders because it is the simplest and cheapest structure. Once your annual profit consistently exceeds $100,000 to $120,000, you employ staff or subcontractors, or you work on larger contracts carrying liability risk, a company or trust structure typically makes more financial sense. A trades accountant can model the tax difference for your specific income level.
What is TPAR and does my trade business need to lodge it?
The Taxable Payments Annual Report (TPAR) is an ATO requirement for businesses in building and construction, and several other industries, that pay contractors. If your business pays contractors for building and construction services, you must lodge a TPAR by 28 August each year. Penalties apply for failure to lodge.
Can I claim tools and equipment as a tax deduction?
Yes. Tools, equipment, vehicles, and work-related technology used in your trade business are generally deductible. The instant asset write-off allows eligible businesses to deduct the full cost of qualifying assets in the year of purchase. Confirm eligibility and the current threshold with your accountant before making a large purchase.
How do I manage cashflow when clients are slow to pay?
Progress billing, clear payment terms in your contracts (net 14 is standard, not net 30), a business credit facility for cashflow gaps, and a separate account for GST all help. Track retentions actively. A tradie owed $40,000 in retentions across five jobs has real money sitting uncollected. Your accountant can help you build a simple cashflow forecast.
What software should a trades business use for accounting?
Xero is the most widely used cloud accounting platform for Australian small businesses and integrates with most trades job management apps, including ServiceM8, Tradify, Buildxact, and Fergus. The right setup depends on your business size, whether you quote and invoice in the field, and how many employees you manage. Ask your accountant for a recommendation before committing. The wrong setup costs time and money to undo.
How often should I meet with my accountant?
For a growing trades business, quarterly is the minimum worth aiming for. A quarterly review lets your accountant catch cashflow problems early, adjust PAYG instalments, flag ATO changes affecting your business, and make sure you’re on track for year-end. Sole traders earning under $80,000 can often get by with twice yearly, but should always have a pre-30 June review.
2026–27 Federal Budget: What It Means for Brisbane Tradies
The 2026–27 Federal Budget, handed down on 12 May 2026, includes several changes that directly affect how trades businesses manage super, structure their business, and claim deductions. Here is what you need to know.
Payday Super – compliance changes from 1 July 2026
Super Guarantee contributions must now be paid with every pay run, not quarterly. This is already in effect. If you have employees and have not updated your payroll process, speak to your accountant now. Late or missed payments trigger the Superannuation Guarantee Charge.
Instant asset write-off permanently extended at $20,000
The $20,000 instant asset write-off for eligible small businesses (turnover under $10 million) has been permanently extended from 1 July 2026. Previously extended year-by-year, the threshold is now settled. Tools, equipment, and plant under $20,000 can be fully deducted in the year of purchase. Confirm your eligibility with your accountant.
Discretionary trusts – 30% minimum tax from 1 July 2028
The Government has proposed a 30% minimum tax on the taxable income of discretionary trusts from 1 July 2028. If you operate through a family trust and currently distribute income to lower-income family members to reduce tax, this change will limit that benefit. The Government has also announced a rollover relief window from 1 July 2027, allowing businesses to restructure out of a discretionary trust into a company or fixed trust. If this applies to you, the time to act is before July 2027 — not after.
Income tax rates reduced from 1 July 2026
The lowest marginal tax rate has dropped from 16% to 15% on income between $18,201 and $45,000. It drops again to 14% from 1 July 2027. Sole traders will see a modest reduction in their annual tax bill – up to $268 less in 2026–27, and up to $536 less in 2027–28. If you have a PAYG withholding arrangement, ask your accountant to update your instalments.
$1,000 instant work-related deduction for sole traders
From the 2026–27 income year, eligible workers including sole traders can claim an automatic $1,000 deduction for work-related expenses without keeping receipts. If your work-related expenses exceed $1,000, you can still claim the higher amount using normal substantiation rules.
