Stamp Duty Calculator Australia

What This Calculator Estimates

Stamp duty on property purchases in Australia is a state and territory tax, meaning rates, thresholds, and concessions (such as for first-home buyers) vary significantly depending on which state or territory the property is in, rather than following one national schedule. Because each state government sets its own rules, this calculator provides a general estimate — confirm exact figures against your specific state's current official rate table.

  2. Enter an estimated stamp duty rate.

Frequently Asked Questions

Is stamp duty the same across all Australian states?

No, each state and territory sets its own stamp duty rates, thresholds, and concessions, so the same property price can result in different stamp duty amounts depending on location.

Do first-home buyers get concessions in Australia?

Yes, most states offer some form of first-home buyer concession or exemption, though the specifics vary significantly by state — check your state revenue office for current rules.

Is stamp duty progressive?

Generally yes, most states use a banded structure where different portions of the property price are taxed at different rates.

Does property type affect the stamp duty rate?

In some states, factors like whether the property is your primary residence, an investment property, or vacant land can affect the applicable rate or available concessions.

Where can I confirm current official rates for my state?

Each state's Revenue Office (such as Revenue NSW, State Revenue Office Victoria, etc.) publishes current stamp duty rate tables and concession eligibility.

This calculator provides Australia stamp duty estimates only. Official state rates and property rules can change, so verify current guidance before relying on the result.

Current Rate
