Stamp Duty Calculator (Australia)

It applies a single flat rate you choose to your property price — it is not a per-state marginal duty calculator. Transfer duty is actually set by each state on its own scale (a fixed amount for the price band plus a rate on the excess), which this tool does not model. The state selector exists to point you to the right revenue office, not to change the rate applied.

No — that's a common myth. First-home buyer concessions depend on the state, property value, and eligibility criteria. You can enter your own concession amount to see its effect, but the tool doesn't look up eligibility or amounts for you.

First-home buyer exemptions and concessions vary significantly by state, and both the thresholds and the concession amounts change over time. This calculator does not carry a state-by-state table — it estimates duty from the rate and any concession amount you enter. Check your state or territory's Office of State Revenue for the current exemption thresholds before relying on a figure.

Most Australian states apply a foreign buyer surcharge on top of the regular duty, but the rate differs by state and changes over time, so this calculator does not carry a surcharge table. If you're a foreign buyer, get the current surcharge rate from your state or territory revenue office and add it to the property price before estimating, or fold it into the rate you enter.

Stamp duty is a state tax, not a federal one — the ATO has no role in it. It is administered and assessed by each state's own revenue office (for example, Revenue NSW or the State Revenue Office Victoria), with final assessment at settlement. This tool provides estimates only, so always cross-check with your conveyancer or your state revenue office for the official duty amount.
