How stamp duty works
Stamp duty (also called transfer duty) is a state tax payable when you buy property. Each state/territory sets its own rates, thresholds and concessions. Eligibility often depends on price, buyer type (first‑home buyer, investor), and whether it’s a new or established home.
- Dutiable value: usually the higher of the purchase price and market value.
- When it’s due: typically within days to months of settlement depending on the state.
- Common concessions: first‑home buyer relief, principal place of residence, off‑the‑plan rules, pensioner concessions, and foreign purchaser surcharges.
