The basics
How NSW stamp duty works
Top bracket
What is premium property duty?
Premium property duty is the top NSW transfer duty bracket. It applies when the dutiable value is above the NSW premium threshold.
The calculator applies it automatically, so you do not need to split out the premium amount yourself. Mixed-use or unusual transactions may still need advice from Revenue NSW or a qualified professional.

OpenQuestions
NSW stamp duty FAQs
Is stamp duty the same as transfer duty in NSW?
Yes. Stamp duty is the common name. Transfer duty is the official NSW name. They mean the same thing.
Does this calculator work for land purchases?
Yes. It covers land, development sites, and property purchases. Enter the purchase price or dutiable value to get an estimate.
Does it include first home buyer concessions?
No. This gives a general estimate. It leaves out first home buyer, owner-occupier, off-the-plan, pensioner, and other concessions or exemptions.
Does it include the foreign purchaser surcharge?
Yes, when you turn the foreign purchaser toggle on. It adds the 9% surcharge on top of the standard transfer duty.
Why does premium property duty apply automatically?
Premium property duty is just the top transfer duty bracket. When the value is above the NSW premium threshold, the calculator uses that bracket for you. There is nothing to split out by hand.
Is this official tax advice?
No. It is a general estimate to help you plan. For a binding figure, or for a complex or mixed-use deal, check with Revenue NSW or a qualified professional.
