Stamp duty adds to your CGT cost base, so it lowers the tax you pay when you eventually sell. Vestly stores it against the property and tracks cashflow, depreciation and deductions alongside it.

How WA stamp duty works
Western Australia transfer duty is administered by RevenueWA. The general rates below are unchanged since 2008; 2024-25 reforms targeted first-home buyer concessions rather than general rates.
Western Australia transfer duty brackets (FY 2026-27)
| Dutiable value | Duty payable |
|---|---|
| $0 - $120,000 | $1.90 per $100 |
| $120,001 - $150,000 | $2,280 + $2.85 per $100 over $120,000 |
| $150,001 - $360,000 | $3,135 + $3.80 per $100 over $150,000 |
| $360,001 - $725,000 | $11,115 + $4.75 per $100 over $360,000 |
| $725,001+ | $28,453 + $5.15 per $100 over $725,000 |

Worked example
A Western Australian investor buying a $650,000 residential property in Perth pays approximately $24,890 in WA stamp duty (before any first-home buyer concession or foreign-acquirer surcharge).
First-home buyer concessions
First-home buyers pay no duty on homes up to $450,000 with a sliding concession to $600,000 (lifted from $530,000 in May 2024). Vacant land: full exemption to $300,000, concession to $400,000.
Foreign buyer surcharge
Foreign buyers pay an additional 7% Foreign Transfer Duty on residential property.
WA-specific quirks
WA also offers a Concessional Rate of Duty for properties under $200,000 (a flat $1.50 per $100 with $20 minimum) - useful for low-value regional investor purchases.
