Stamp Duty in NSW: What It Is, When It’s Due, and How It’s Calculated

If you’re buying a property, stamp duty is one of those extra costs that can sneak up on you if you’re not prepared. It’s easy to focus on the purchase price and forget about the fees that come with it - but stamp duty can be a significant chunk, so it’s worth understanding early in the process.

When is Stamp Duty Due?

In NSW, stamp duty (also called transfer duty) is due either:

  • At settlement, or

  • Within three months of the contract date
    - whichever comes first.

That means if your settlement is quick, you’ll need to have the funds ready sooner than later.

How Is It Calculated?

Stamp duty is based on several factors:

  • Purchase price of the property

  • Type of buyer (Are you a first-home buyer? An investor?)

  • Eligibility for exemptions or concessions

It’s payable on the Contract and Transfer - and timing matters. Your Conveyancer will make sure everything is lodged correctly, but having an idea of what you might owe is a smart move.
