Understanding Building & Construction Tax

Construction businesses in Australia face a unique mix of tax obligations, making compliance more complex than in many other sectors.

Components of Construction Tax

• Income Tax: Applicable on all construction earnings.
• Goods and Services Tax (GST): The 10% levy on most supplies and services in construction.
• Employer Obligations: PAYG withholding, superannuation, and contractor reporting.

Calculating Taxable Income

Proper tax calculation involves:

• Summing all revenues from services and projects.
• Deducting only legitimate, documented business expenses.
• Separating private usage from company operations.

Eligible base rate construction entities may access a 25% company tax rate instead of the standard 30%. Learn more on our small business tax guide.

Consequences of Non-Compliance

Tax negligence in this industry can be costly:

• Intensive audits and ATO scrutiny.
• Substantial fines for late or incorrect submissions.
• Reputation damage affecting business longevity.

The ATO’s key risk watchlist highlights non-disclosure and contractor misclassification as significant red flags for this sector.

ATO’s Focus on the Construction Sector

Why Construction is Targeted

• Prevalence of unreported cash work.
• Frequent GST misreporting on property transactions.
• Phoenixing tactics exploit the system to evade tax, then reincarnate the same business model.

Tip-offs and Industry Intelligence

Thousands of filed tip-offs arise from:

• Competitors spotting dodgy subcontractor schemes.
• Disgruntled staff reporting off-the-record payments.

Common Compliance Issues

• Income masking between commercial and residential jobs.
• Exaggerating expenses to lower reported profit.
• Improperly using contracting to avoid employer duties.
• GST avoidance by not registering above the $75K threshold.

Challenges Faced by the ATO in the Construction Sector

The Cash Economy Challenge

• Ubiquitous off-record cash deals.
• Undetectable payment chains.
• Hidden payroll to circumvent withholding laws.

The industry’s reliance on paper-based, cash-heavy practices hinders the ATO’s oversight.

Impact on Industry Integrity

“When tax evasion becomes the norm, it hurts every business that does the right thing.” — Industry Auditor

• Legitimate firms struggle to compete on honest margins.
• Public projects lose funding from reduced tax collection.

Data Collection Complications

Without digital receipts or banking trails, the ATO has fewer tools to track money movement, making enforcement more difficult.

Audits and Compliance: ATO’s Approach

Proactive Compliance Model

• Early education and engagement.
• Real-time flagging of anything unusual.
• TPRS reporting tools cross-reference contractor data.

What the ATO Looks for in an Audit

• Underreported income or sales.
• GST inconsistencies across statements.
• Unreported or misclassified worker arrangements.
• Missing super contributions.

The Role of Data Analytics

Modern ATO audits now rely on powerful analytics that:

• Compare business activity to industry norms.
• Track TPRS forms submitted by other entities.
• Identify gaps between contractor income vs payer reports.

FAQ

What is TPRS and how does it affect construction businesses?

TPRS stands for Taxable Payments Reporting System. It mandates construction businesses to report payments made to contractors, enabling the ATO to cross-check reported income and ensure all taxes are paid accurately.

Why is the construction sector under more ATO scrutiny than others?

Due to a historical pattern of tax evasion, unreported cash payments, and phoenixing, the ATO has designated construction as a ‘high-risk’ sector and implemented focused audit programs accordingly.

How can I reduce audit risk in my construction business?

Maintain accurate, digitised records of income and expenses, register for GST as required, classify workers properly, and keep contractor payments honest and declared. Proactive compliance reduces risk.
