Key points
- Rates and thresholds depend on property value and buyer type (FHB, investor, etc.).
- Concessions may apply for eligible first‑home buyers or principal place of residence.
- Foreign buyer surcharges may apply.
Current concessions and surcharges
- From 7 May 2026, eligible first-home buyers may pay no duty on a qualifying home valued up to $600,000.
- For qualifying homes above $600,000 and up to $800,000, the first home owner rate provides concessional treatment.
- For qualifying vacant land, the current thresholds are no duty up to $450,000 and concessional treatment above that amount up to $550,000.
- Foreign transfer duty is an additional 7% for relevant foreign acquisitions of residential property.
- Off-the-plan concessions can depend on the contract date and eligibility. Check the current RevenueWA guidance.
The first-home thresholds vary by transaction date and, in some cases, location. Confirm the current assessment rules with RevenueWA.
Worked example — $500,000 property
For a dutiable value of $500,000, the property falls within the $360,001 to $725,000 general-rate bracket.
- Rate formula: $11,115 + $4.75 per $100 or part thereof above $360,000
- Amount over threshold: $500,000 − $360,000 = $140,000
- Duty on excess: $140,000 ÷ $100 × $4.75 = $6,650
- Total transfer duty: $11,115 + $6,650 = $17,765
This example uses WA's general transfer duty rate only. First-home buyer rates, foreign transfer duty and other concessions can change the final amount.
