Your build deserves an accountant

The problem
Most accountants see “income and expenses.” Construction isn’t that simple.
Construction businesses carry financial obligations, compliance risks, and cash flow dynamics that simply don’t exist in other industries. If your accountant isn’t across these specifically, the gaps they leave can cost you — in tax, in ATO penalties, and in personal financial exposure.
TPAR obligations missed If you pay contractors, you’re likely required to lodge a Taxable Payments Annual Report. Penalties apply.
Cash flow blind spots Progress claims, retentions, and slow payments create gaps that catch even profitable businesses off guard.
Wrong business structure Sole traders in construction carry significant personal risk. The right structure depends on how you operate.
Personal assets exposed Without the right strategy, your home and personal wealth can be at risk from project disputes or claims.

Residential builders, commercial builders, property developers, and project managers overseeing large or complex developments.
Subcontractors & Tradies
Electricians, plumbers, concreters, carpenters, painters and all trades — whether sole trader or operating a team.
Growing Construction Businesses
Established operators ready to scale — needing smarter structure, better cash flow visibility, and a strategy to protect what they’ve built.
Our services
Accounting built around how construction businesses actually operate
Every service we deliver is informed by a deep understanding of how the industry works — from project-based income and subcontractor payroll to the compliance obligations most accountants overlook.
Bookkeeping for Construction
Accurate, timely financial records built around how construction businesses actually operate — project-based income, variable subcontractor costs, and progress claim timing.
Integrates with Xero, MYOB, and your existing systems. Tailored for subcontractors and multi-site operators.
Business Structure Advice
The wrong structure in construction leaves your personal assets exposed and your tax position inefficient. We advise on the structure that fits your risk profile, income level, and growth plans.
Sole trader, company, trust, or partnership — the right answer depends on your specific situation, not a template.
Business Consulting
Practical financial advice for construction owners who want to understand their numbers, manage cash flow, and make confident decisions about growth, equipment, and staffing.
Cash flow modelling, project margin analysis, and forward planning for your construction business.
Tax Accounting
Optimise your tax position across the full picture — income tax, GST, FBT, payroll tax, and BAS preparation. Construction businesses have deduction opportunities most generalists miss.
Includes TPAR lodgement management, depreciation on plant and equipment, and vehicle cost structuring.
Financial Accounting
Clear, accurate reporting that tells you how your business is performing — across projects, across the year, and relative to industry benchmarks that matter.
Work In Progress (WIP) reporting, project profitability analysis, and financial statements to industry standards.
Asset Protection Strategies
Construction is one of the highest-risk industries for personal financial exposure. The right protection strategy means that if something goes wrong on a project, your home and personal wealth are not at risk.
Tailored strategies built around your personal assets, business risk, and long-term goals.
Industry knowledge
The compliance obligations construction businesses can’t afford to get wrong
These are the areas where a specialist accountant makes a real difference — and where a generalist one can cost you.
TPAR
Taxable Payments Annual Report
If your business pays contractors, you’re likely required to lodge a TPAR with the ATO each year. We manage this process entirely for construction clients — no penalties, no missed deadlines.
WIP
Work In Progress Reporting
WIP accounting tells you the true profitability of every project in real time — not just at completion. Understanding your WIP position is critical for construction cash flow and business health.
BAS / GST
BAS Preparation & Lodgement
Construction GST is complicated — progress claim timing, subcontractor GST status, and the margin scheme all intersect. We handle this accurately and on time, every time.
STRUCTURE
Business Structure & Asset Risk
Your structure determines how exposed your personal assets are when things go wrong. We advise on structures that separate personal wealth from business risk — essential in construction.

Common questions
Frequently asked questions from construction business owners
Construction businesses face financial obligations that simply don’t exist in other industries — Taxable Payments Annual Reports (TPAR), Work In Progress (WIP) accounting, retention receivables, variable subcontractor payroll, and complex project-based cash flow. A generalist accountant who isn’t across these can leave you non-compliant with the ATO, overpaying tax, or blind to cash flow problems until it’s too late. The right specialist pays for themselves many times over.
TPAR stands for Taxable Payments Annual Report. If your construction business pays contractors for services, you’re generally required to lodge a TPAR with the ATO each year by 28 August. Missing or incorrect TPAR lodgements attract ATO penalties. At Diagnostic Accounting, we manage this process entirely for construction clients — so nothing slips through and your compliance obligations are met without it becoming your problem.
There’s no universal answer — the right structure depends on your revenue, risk profile, number of employees, growth plans, and personal asset exposure. Construction is a high-liability industry, and the wrong structure can leave your home and personal savings exposed if a project dispute or claim arises. We provide specific business structure advice based on your individual situation, not a template.
Cash flow is one of the most common pressure points in construction — you’re often paying wages and materials long before a progress claim is paid or a project is completed. A specialist accountant can model your project cash flow, help you time major purchases around BAS obligations and tax deadlines, and identify where money is being lost. The goal is clear financial visibility — so you’re never caught short between jobs.
We work with clients across the full spectrum of the construction industry — from sole-trader tradies and independent subcontractors through to established building companies and property developers. Our advice is always tailored to your current stage of business, not a one-size approach. If you’re in construction, there’s a good chance we can help.
Construction businesses have access to a wide range of legitimate deductions — tools and equipment, vehicles, protective clothing, training and licensing, home office use, and depreciation on plant and machinery. The specifics depend on your business structure, how you operate, and your income type. The most important thing is speaking with an accountant who understands construction before your tax return is due, not after.
Asset protection in construction starts with your business structure — but it doesn’t end there. Personal assets can be at serious risk in sole trader arrangements or poorly structured companies if a dispute or liability event occurs. The right strategy depends on what you own personally, the nature of your work, and your longer-term goals. Diagnostic Accounting specialises in asset protection strategies for business owners in high-risk industries, including construction.
