Stamp Duty by State: The $20k–$40k Line on Your Settlement

Transfer duty (stamp duty) is the largest single transaction cost in Australian property — and because each state and territory sets its own scales and concessions, the same $800,000 purchase can cost roughly $20,000 in one state and over $40,000 in another. It's paid in cash at or shortly after settlement and can't be rolled into most loans.

Treat these as order-of-magnitude figures: every revenue office publishes an official calculator, scales change at state budgets, and foreign-buyer surcharges (7–8% extra in most states) sit on top where they apply.

First home buyer concessions — the big lever

Budget rule: duty plus conveyancing, inspections and registration typically adds 4–5% of the purchase price in upfront cash for a non-exempt buyer. If you're saving a 20% deposit, the real target is closer to 25%.

Why the state you buy in matters more than almost anything else

Stamp duty is the single largest entry cost of buying in Australia, it is set entirely by each state and territory, and the spread between them is enormous. On the same purchase price the duty can differ by tens of thousands of dollars depending only on which side of a border the property sits.

It is also payable in cash at settlement and cannot be added to the loan, which is why it — rather than the deposit alone — is what most often delays a purchase.

First home buyer concessions by approach

The states have diverged sharply in how they treat first home buyers:

The costs that sit alongside it

Because concessions, thresholds and surcharges all change at state budgets, the only reliable figure is the one from your own state revenue office on the day you buy.

Frequently asked questions

How much is stamp duty in Australia?
It is set by each state and territory rather than federally, and typically runs 3-6% of the purchase price on a sliding scale. Government transaction costs together commonly reach 4.5-5.5% of the price, which makes duty the largest single cost of buying after the deposit.

Do first home buyers pay stamp duty?
Every state and territory offers first home buyer concessions or exemptions, but the thresholds and conditions differ substantially — and in the most expensive markets the concession cuts out below the median house price, so many first buyers pay in full.

Can stamp duty be added to the mortgage?
Generally no. It is payable in cash at settlement and sits on top of the deposit, which is why the cash required to buy is considerably more than the deposit figure suggests.

Is stamp duty being replaced?
Some jurisdictions have introduced or trialled an annual land tax as an alternative to a one-off duty, on the argument that duty penalises moving. Where a choice exists, it turns on how long you expect to hold the property — the annual option favours shorter holds.
