Stamp Duty on Property Purchases: State Rates and Concession Policies Explained

What stamp duty on a property purchase actually is

When a property changes hands, the buyer normally pays a transfer duty — often called stamp duty — to the state or territory government where the property sits. The amount is not set nationally. Each state and territory runs its own duty scale, its own concession schemes and its own surcharge rules.

That single fact explains most of the confusion buyers run into. A rate quoted for one jurisdiction does not carry across a border, and a concession announced in one state does not automatically apply in another.

Why the same purchase can attract very different duty

Several variables feed into a duty assessment, and they interact differently in each jurisdiction:

• The jurisdiction. The property's location determines which revenue office assesses the duty and which scale applies.
• The purchase price or value. Duty scales are tiered, so the rate applied to a higher portion of the price is generally higher than the rate on the first portion.
• The buyer's category. First home buyers, and in some places other defined buyer groups, may face a different treatment from a standard purchaser.
• Residency status. Foreign buyers can face an additional duty or surcharge on top of the standard assessment in jurisdictions that levy one.

The practical consequence is that two buyers paying the same price for similar homes in different states can owe noticeably different amounts, and the gap widens further once concessions or surcharges enter the picture.

How the duty is calculated

At its simplest, a duty assessment applies the jurisdiction's rate scale to the dutiable value of the transaction. Because the scales are tiered rather than flat, the calculation is rarely a single percentage multiplied by the whole price. Instead, the scale is applied progressively, with each portion of the value taxed at the rate set for that tier.

A few points follow from that structure:

• Moving into a higher tier does not normally re-rate the entire purchase. It changes the rate on the portion that falls into the higher band.
• Different jurisdictions set different tier boundaries and different rates within those tiers, so the point at which the effective rate rises varies by location.
• The dutiable value is not always identical to the headline purchase price. Adjustments can apply depending on how the transaction is structured and what the jurisdiction includes in the assessment.
• Because concessions and surcharges are layered on top of the base assessment, the final payable figure can differ substantially from the raw scale calculation.

Buyers comparing scenarios across states should therefore compare final payable amounts under each jurisdiction's own rules, rather than comparing headline rates.

Concessions for first home buyers

First home buyer concessions are a recognisable feature of the stamp duty landscape, but they are designed and delivered jurisdiction by jurisdiction. That produces several practical effects:

• Eligibility is local. A buyer who qualifies for a concession in one state or territory may not qualify in another, because each sets its own criteria.
• The benefit may take more than one form. Depending on the jurisdiction, relief can appear as a full exemption, a reduced duty amount, or a concession that phases out as the purchase price rises.
• Value thresholds matter. Where a scheme applies a price or value cap, a purchase above that cap typically loses access to the concession, or sees the benefit taper.
• Buyer characteristics can be part of the test. Schemes commonly define who counts as a first home buyer, and that definition is set by the jurisdiction rather than universally.

For a buyer, the reliable approach is to identify the jurisdiction first and then check that jurisdiction's current first home buyer arrangements, rather than assuming a concession seen elsewhere will transfer.

Additional duty for foreign buyers

Several jurisdictions apply an additional duty or surcharge to foreign buyers on top of the standard assessment. Where such a charge exists, it generally operates as a layer added to the base duty rather than replacing it, which means the total payable can be meaningfully higher than for a resident buyer at the same price.

Two cautions are worth keeping in mind. First, whether a surcharge applies at all depends on the jurisdiction; it is not a uniform national charge. Second, the definition of a foreign buyer, and any exemptions or thresholds attached to the surcharge, are set locally. Buyers who may fall into this category should establish the position in the specific jurisdiction where they intend to purchase before committing to a budget.

Foreign investment approval is a separate matter from duty. Duty is a state or territory revenue question; approval to purchase is handled through a different process entirely, and the two should not be treated as interchangeable steps.

Sorting out the numbers before you commit

Because duty sits alongside other purchase costs, it helps to treat it as a line item to be estimated early rather than resolved at settlement. A workable sequence looks like this:

1. Identify the state or territory where the property is located — this determines the rulebook.
2. Establish which buyer category applies, including first home buyer status and residency status.
3. Work out the dutiable value under that jurisdiction's rules, not simply the advertised price.
4. Apply the jurisdiction's rate scale, then apply any concession or surcharge that the buyer's circumstances attract.
5. Check the result against the revenue office's own guidance for that jurisdiction, since schemes and thresholds change.

Steps one and two are where most errors originate. Buyers who start from a national average, or from a rate they saw applied in another state, typically have to redo the estimate once the correct local rules are applied.

FAQ

Is stamp duty the same rate across Australia? No. Each state and territory sets its own duty scale, its own concessions and its own surcharge rules, so the rate and the final payable amount depend on where the property is located.

Can two buyers paying the same price owe different stamp duty? Yes. The buyer's category and residency status can change the assessment, and concessions or foreign buyer surcharges are layered on top of the base duty in jurisdictions that provide for them.

Do first home buyer concessions work the same way everywhere? No. Eligibility criteria, the form the benefit takes and any value thresholds are determined jurisdiction by jurisdiction, so a concession available in one state or territory may not be available in another.

Is the foreign buyer surcharge a national charge? No. It is a jurisdiction-level layer added to the standard duty where it exists, and the definition of a foreign buyer and any related exemptions are set locally.
