Stamp Duty Calculator Australia 2025–26

First-home-buyer concession thresholds verified 5 August 2026: NSW exemption to $800k (concession to $1M), VIC $600k/$750k, QLD $700k/$800k, WA $500k/$700k metro, ACT Home Buyer Concession to $1.02M (income-tested — check eligibility), NT none. SA’s relief applies to new homes/off-the-plan only (no price cap) and is not modelled here; Tasmania’s concession lapsed 30 June 2026. Base duty scales use published brackets — NSW and ACT index theirs annually, so figures there can vary slightly. Always confirm with your state revenue office.

How Stamp Duty Works in Australia

Stamp duty — officially called transfer duty — is a state government tax you pay when buying property. Each Australian state and territory sets its own rates, thresholds, and concessions, which means the same property value can attract very different duty amounts depending on where you buy.

Progressive Bracket System

Like income tax, stamp duty uses progressive brackets. You don't pay the top rate on the entire purchase price — each portion is taxed at its own marginal rate. For example, on a $750,000 property in NSW, the first $17,000 is taxed at 1.25%, the next $20,000 at 1.5%, and so on up through the brackets.

First Home Buyer Concessions

Most states offer significant stamp duty relief for first home buyers. NSW provides full exemption on properties up to $800,000. Victoria exempts purchases up to $600,000. Queensland removed the price cap entirely for new homes from May 2025. Tasmania’s first home buyer duty concession lapsed on 30 June 2026 with no replacement announced — Tasmanian first home buyers now pay full transfer duty, though a $20,000 First Home Owner Grant remains for new builds (1 July 2026 – 30 June 2027 window).
