GST/BAS & STP Lodgement Errors & ATO Penalties
Definition
Contractors who cannot clearly prove labour hours by task/cost code struggle to allocate revenue correctly for BAS purposes. Manual spreadsheets merge labour across cost centres, making it impossible to audit which hours were billable, which were non-taxable, and which attracted penalty rates. GST miscalculation and late lodgement attract ATO interest (10% p.a.) and penalties (25–50% of tax debt for dishonest conduct).
Key Findings
- Financial Impact: AUD 2,000–6,000 per annum in BAS correction costs and interest; STP Phase 2 penalty up to AUD 13,500 per year for non-compliance
- Frequency: Quarterly (BAS lodgement cycle); ongoing (STP reporting pressure from mid-2026)
- Root Cause: No clear labour cost coding; timesheets not linked to tax categories; manual BAS reconciliation; no API integration to ATO-compatible accounting software
