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 offers the cleanest structure with full exemption up to $750,000.
