Stamp Duty Calculator Australia 2026

How Stamp Duty Works in Australia

Stamp duty, formally known as transfer duty, is a state government tax charged whenever a property changes ownership. The buyer pays this tax to the relevant state or territory revenue office, and the amount is calculated as a percentage of the property's purchase price or market value (whichever is higher).

Each state sets its own rates and thresholds, and the rates are progressive, meaning higher-value properties attract higher marginal rates. For property investors, stamp duty directly increases your total acquisition cost and affects your rental yield calculations.

Stamp Duty and Your Investment Strategy

When evaluating an investment property, stamp duty should be factored into your total acquisition cost alongside legal fees, building inspections, and loan establishment fees. This total cost is what you should use when calculating your net rental yield and break-even timeline. Learn more about the property settlement process to understand all the costs involved.
