Simplify Compliance, Strengthen Performance

Tax & GST for Builders and Subcontractors

Simplify Compliance. Strengthen Performance. Protect Margins.

Construction businesses face unique financial pressures — irregular progress payments, retention delays, subcontractor classification risks, and tight job margins that can disappear without proper oversight.

At 42 Advisory, we help Melbourne builders and subcontractors stay compliant while building a stronger financial structure behind every project.

The Financial Challenges Builders Face

Many construction businesses struggle with:

Cash flow gaps between progress claims and supplier payments
GST timing on progress payments and retention amounts
Misclassifying contractors vs employees (ATO risk)
Underestimating job costs due to poor margin tracking
PSI/PSB rules affecting subcontractors
Unplanned tax liabilities disrupting working capital

Without structured systems, profitable jobs can still result in cash flow stress.

Case Study:

Melbourne Demolition Business — Cash Flow Forecasting and Growth Planning

A Melbourne-based demolition company with 8 employees, multiple trucks, and specialised equipment approached us during a growth phase. While the work pipeline was strong, the directors lacked clear forecasting around cash flow, labour costs, and their capacity to acquire an additional truck and equipment to expand operations. Overtime, weekend work, and public holiday penalty rates were being managed manually, limiting visibility over true job margins. We implemented structured 3-way forecasting and modelled the proposed asset acquisition to assess debt capacity, GST timing, and tax implications — ensuring expansion could be funded without placing pressure on working capital.

Alongside strategic acquisition planning, we introduced an integrated payroll system that accurately captured overtime, public holiday, and weekend rates while strengthening STP compliance. This provided real-time labour cost allocation to projects, improved margin visibility, and ensured the team was paid correctly and transparently. With structured reporting and forecasting in place, the business successfully expanded its fleet, improved profitability tracking, and positioned itself for sustainable growth rather than reactive scaling.

YOU MAY NEED TO KNOW

Frequently Asked Questions – Builders & Contractors Accounting in Melbourne

Do builders need a specialist accountant?

Yes. Builders face complex GST obligations on progress claims, subcontractor payment rules, retention accounting, and project-based profitability tracking.

A specialist construction accountant ensures ATO compliance while improving cash flow visibility and job-level margin reporting across every project.

How does GST work for builders in Australia?

Builders charge 10% GST on taxable supplies and claim input tax credits on eligible business purchases. Complexity arises with progress payments, retention amounts, and mixed-use developments.

Accurate GST reporting on BAS lodgements is critical to avoid ATO audit risk and cash flow shortfall

What tax deductions can trade businesses claim?

Trade businesses can deduct tools and equipment, vehicle expenses, work-related travel, protective clothing, subcontractor payments, insurance premiums, and eligible asset write-offs under the instant asset write-off rules. A structured tax plan with a CPA ensures all legitimate deductions are captured each financial year.

How can builders improve cash flow?

Builders improve cash flow through progress claim forecasting, disciplined retention release scheduling, structured supplier payment terms, and accurate PAYG and GST liability forecasting. Implementing 3-way forecasting across profit, cash flow, and balance sheet prevents the timing failures that cause most construction insolvencies.

Should subcontractors operate as sole traders or companies?

It depends on income level, risk exposure, asset protection needs, and growth plans. A company structure offers liability protection and tax planning flexibility, but the ATO’s personal services income rules may restrict profit distribution. A CPA can assess the optimal structure for each situation.

What accounting software is best for builders?

Xero is commonly used due to:

Project tracking
Integration with job management tools
Real-time reporting
Payroll compliance

Construction businesses benefit from integrated job costing systems.

Do builders need payroll compliance support?

Yes. Builders employing staff must manage:

EBA Compliance
PAYG withholding
Superannuation
STP reporting
Subcontractor classification risks

Misclassification of contractors can trigger ATO penalties.

Can a builder reduce tax legally?

Yes, through:

Proper entity structuring
Timing of income and expenses
Asset write-off planning
Superannuation contributions
Division 7A planning (if operating via a company)

Strategic tax planning must comply with Australian tax law.
