Frequently asked questions
Does stamp duty vary by state?
Yes, each Australian state and territory sets its own rates and thresholds, so the amount can differ significantly depending on where you're buying.
Are first-home buyers charged differently?
Many states offer stamp duty concessions or exemptions for first-home buyers — check your state revenue office for specifics.
Is stamp duty a one-time cost?
Yes — it's paid once at the time of purchase/settlement, unlike ongoing costs like council rates or land tax.
Does the property being an investment vs. owner-occupied change the rate?
In some states, yes — certain concessions only apply to owner-occupied homes, while investment properties are charged the standard rate.
