GST Classification & Pricing Errors in Variable-Quantity Contracts
Definition
Model Contract 3 (Variable Quantity/Royalty Basis) stipulates that timber is purchased 'satisfying the specifications and available in compliance with the conditions set out in the Forest Harvesting Operational Plan'[2]. Payment is calculated per the Plan schedule but depends on actual volume harvested. GST must be applied on the GST-exclusive price[1]. Without automated mapping of harvested logs to contract price tiers (sawlog vs. salvage, premium vs. standard grades), landowners underbill or purchasers underremit, and the ATO may flag inconsistent GST reporting.
Key Findings
- Financial Impact: Estimated 2–4% revenue leakage per contract (AUD $10,000–$40,000 on a AUD $500,000–$1,000,000 operation). ATO penalties for incorrect GST classification: AUD $2,100–$21,000 per audit period (10–100% of under-remitted GST)
- Frequency: Per harvest cycle; compounded quarterly during BAS/GST lodgement
- Root Cause: Manual grading/classification at harvest, no real-time mapping to contract price schedule, paper-based delivery dockets, disconnection between harvest system and invoicing/tax accounting system
