Formula

Duty Estimate = Purchase Price x Stamp Duty Rate / 100

Australian stamp duty is state-administered with progressive marginal schedules. This calculator uses approximate default rates by state with an optional override for your exact rate.

Worked Example

Purchase price A$700,000 in NSW. Using approximate NSW schedule gives estimated stamp duty of around A$26,000 to A$28,000 depending on exact brackets and concessions.

How Australian Stamp Duty Varies by State

Australian stamp duty (officially called transfer duty in most states) is a state-administered tax on property purchases. Each state sets its own progressive rate schedule, thresholds, and concessions, creating significant differences in costs.

NSW has been transitioning some buyers to an optional annual land tax model instead of upfront stamp duty
Victoria has the highest stamp duty rates, with a premium rate of 6.5% applying to portions above A$960,000
Queensland offers significant concessions for first home buyers including full exemption on properties under A$500,000
Western Australia and South Australia have their own progressive schedules with first home buyer exemptions at lower thresholds

This calculator uses approximate rates by state. For exact calculations, use your state revenue office official calculator, as concessions, exemptions, and thresholds change frequently.

You can also calculate changes using our Australia GST Calculator or UK Stamp Duty Calculator.
