Stamp Duty in Australia: What Every Home Buyer Needs to Know

Introduction

Stamp duty is one of the largest upfront costs you'll face when buying property in Australia — and one of the most commonly underestimated. Most buyers spend months focusing on saving a deposit and getting pre-approved for a home loan, then discover at settlement that there's an additional five-figure tax bill waiting for them that they hadn't fully accounted for.

Whether you're a first home buyer working out what you actually need to save, or you've bought before and are planning your next purchase, understanding stamp duty before you start property hunting is essential. It affects how much cash you need to have ready at settlement, your effective loan-to-value ratio, and in some cases, whether a particular property is financially viable at all.

This guide explains what stamp duty is, how it's calculated across each Australian state and territory, which concessions may apply to you, and — most importantly — why you need to know all of this before you fall in love with a property.

What Is Stamp Duty?

Stamp duty — also known as transfer duty — is a tax charged by state and territory governments when ownership of a property changes hands. It's one of the primary revenue sources for state governments, and it's been part of the Australian property market since colonial times. The name itself dates back to when a physical stamp was pressed onto the legal document as proof that the tax had been paid.

Who charges it?

Stamp duty is a state and territory tax, not a federal one. This means the rates, thresholds, and available concessions differ depending on where in Australia you're buying. What you pay on a $700,000 property in Queensland can be significantly different from what you'd pay for the same property in Victoria or New South Wales.

Who pays it?

The buyer pays stamp duty. So it's not included in the sale price of a property, and it's not optional — although there are conditions when you might not have to pay any stamp duty at all! We'll get to that in a bit.

What triggers stamp duty?

Stamp duty applies whenever real estate ownership is formally transferred. This most commonly occurs when you:

• Purchase a residential property (house, apartment, townhouse, or land)
• Purchase an investment property
• Receive a property as part of a business acquisition

Some transfers — such as certain family transfers or transfers between spouses as a result of relationship breakdown — may be exempt or reduced in some states. But these are exceptions with strict qualifying criteria, not general rules.

What is it calculated on?

Stamp duty is calculated on the dutiable value of the property — which is the greater of the purchase price or the independent market value at the time of transfer. If you pay $650,000 for a property that a registered valuer assesses as worth $700,000, stamp duty is calculated on $700,000.

How Is Stamp Duty Calculated?

Stamp duty is typically calculated using a tiered, progressive rate structure — similar in concept to income tax brackets. Higher-value properties attract a higher effective rate. But the full rate doesn't apply to the whole price; only the portion of the purchase price within each band is taxed at that band's rate.

However, each state and territory sets its own rules. So, each have their own bands and rates, and each have their own way of calculating rates. So, depending on where you live, and how much the property is, you could be taxes using a tiered rate structure, or face a flat percentage across the entire value of the property, or even have your rate determined by a mathematical quadratic equation! Plus, if you're a first-home buyer (often refered to as an FHB) then you might not have to may anything at all! So it's definitely not a case of one rule for everyone!

A worked example — New South Wales

Let's say you purchase a $600,000 established home in NSW as an existing homeowner (not a first home buyer). The NSW transfer duty calculation looks like this:

Example: A $600,000 property in NSW sits in the $364,001–$1,212,000 bracket. You pay a fixed $10,909 on the first $364,000, then 4.5% on the remaining $236,000, which comes to $10,620. Total stamp duty: $21,529.

That $21,529 must be in your bank account at settlement — on top of your deposit.

Now compare that to a first home buyer purchasing the same $600,000 property in NSW. Because NSW exempts first home buyers from transfer duty on properties valued under $800,000, the stamp duty bill for that buyer is $0.

Same property. Same settlement date. $21,529 difference. That's the real-world impact of knowing your eligibility — or not — before you buy.

What determines how much you pay?

So, four main factors shape your stamp duty bill:

Property value: The higher the purchase price, the more you pay. Stamp duty rises non-linearly — a $1 million property doesn't just cost twice the stamp duty of a $500,000 property; as a proportion, it costs considerably more.

State or territory: Each jurisdiction has its own rate schedule, and some are materially more expensive than others for the same purchase price.

Your buyer status: First home buyers receive concessions or full exemptions in most states. Investment property buyers almost always pay the full rate with no concessions.

Property type: Off-the-plan purchases, vacant land, and new homes may attract different rates or additional concessions depending on your state.

State-by-State Overview

With all those factors at play, it's time to dive into what all those variables actually mean for you, for the property you want, and where you live. The overview below summarises what you can expect in each jurisdiction for a standard residential purchase. Whilst rates and thresholds are reviewed regularly — always verify current figures with the relevant state revenue office, or use a dedicated calculator before making any financial decision (such as the one here on MoneyMart)

New South Wales
For a $600,000 standard purchase: approximately $21,529. First home buyers are fully exempt on properties under $800,000, with a concessional rate between $800,000 and $1,000,000. NSW has also introduced an optional annual property tax for some owner-occupiers as an alternative to paying upfront duty.

Victoria
Victoria's rates reach up to 5.5% for properties over $960,000. First home buyers purchasing a new home priced under $600,000 pay no duty at all; the concession phases out to $750,000. Established homes attract full duty rates regardless of buyer type above applicable thresholds.

Queensland
Queensland applies a concessional rate for owner-occupied homes rather than an outright first home buyer exemption. A standard buyer purchasing for $500,000 pays approximately $8,750. First home buyers may also be eligible for the First Home Concession, which reduces duty on properties under $700,000.

Western Australia
WA offers one of the more generous first home buyer positions: full duty exemption on properties under $430,000, with a sliding concession available up to $530,000. For non-first home buyers, a $500,000 property attracts approximately $17,765 in duty.

South Australia
SA operates a standard sliding scale with no standalone first home buyer stamp duty exemption (the First Home Owner Grant is the primary state support mechanism). A $500,000 property attracts approximately $21,330 in duty.

Tasmania
Tasmania's rates follow a tiered structure. A $500,000 property attracts approximately $18,247 in duty. First home buyers buying a new home may be eligible for a concession under the First Home Owner Grant scheme.

Australian Capital Territory
ACT currently has a tiered system ranging from 0.28% for sums under $260,000, up to 6.4% for sums under $1,455,000, and then a flat 4.5% for any properties above this value. ACT properties for first-home buyers also incur no stamp duty for properties under $1,200,000. Check the ACT Revenue Office for current thresholds.

Northern Territory
NT's rules for applying Stamp Duty depends on the value of the property. Properties under $525,000 use a quadric formula for calculating cost, whereas properties over that amount have a flat percentage rate applied to the entire amount, but that rate gets higher the more the property is worth. So a $500,000 property attracts approximately $23,989. First home buyers building a new home may be eligible for a reduction under the Territory Home Owner Discount.

First Home Buyer Concessions

If you're buying your first home, stamp duty concessions are one of the most tangible financial benefits available to you — in some states saving you $20,000 or more on a single transaction. Here's what you need to understand.

Concessions don't apply automatically

This is one of the most important things to know: you must apply for the concession. It doesn't get applied automatically at settlement. You'll typically declare your eligibility when lodging your transfer duty assessment, which your conveyancer or solicitor handles on your behalf. If you don't declare it correctly, you'll be assessed at the standard rate.

Common eligibility requirements

While criteria differ by state, most first home buyer concessions require that:

• You (and your partner, if buying jointly) have never previously owned residential property in Australia
• The property will be your principal place of residence — you're moving in, not renting it out
• You occupy the property within a specified period after settlement, typically within 12 months
• The property value falls at or below the relevant state threshold

Buying your first property as an investment, even if you've genuinely never owned before, disqualifies you from first home buyer concessions in most states.

Buying with a partner

In most states, both buyers must independently meet the eligibility criteria for the full concession to apply. If one partner has previously owned property, you should check the specific rules in your state — some offer a partial concession in this scenario, others don't.

Other Exemptions and Scenarios to Know About

Stamp duty rules have several important nuances beyond the standard first home buyer concession:

Principal place of residence vs investment property: In some states, the rate applied differs based on whether you're buying to live in the property or to rent it out. Confirm which rate applies to your intended use before settlement.

Foreign buyer surcharges: If you're not an Australian citizen or permanent resident, most states impose an additional foreign purchaser duty on top of the standard rate. This is 8% of the dutiable value in New South Wales, 8% in Victoria, and 7% in Queensland. On a $700,000 property, that's an additional $49,000–$56,000 in duty on top of the standard amount — a calculation that fundamentally changes the economics of a purchase.

Family transfers: Some intra-family property transfers — such as between spouses following relationship breakdown, or from parent to child in specific circumstances — may be exempt or concessionally assessed in certain states. These are strictly conditional; your conveyancer can advise whether a specific transfer qualifies.

Off-the-plan purchases: Buying before construction is complete can sometimes reduce your dutiable value base, because duty may be assessed on the contract price minus the construction component completed after contract exchange. Rules vary considerably by state and the specifics of the contract.

Why You Must Know Before You Buy

Understanding stamp duty before you start house hunting isn't just useful — it's critical. The reason comes down to three things: when it's due, how it affects your deposit, and how it shapes your realistic buying range.

It's an immediate cost

In almost all circumstances, stamp duty cannot be added to your home loan. Your lender will not fund it. It must be paid in full by the buyer, although the time that you have to pay it after settlement also differs depending on where you live.

• NSW (New South Wales): Within three months of settlement, or contract execution for off-the-plan.
• VIC (Victoria): Within 30 days of settlement.
• QLD (Queensland): Within 30 days of settlement.
• WA (Western Australia): Within two months of settlement.
• SA (South Australia): On the day of settlement.
• TAS (Tasmania): Within three months of the property transfer (usually settlement).
• ACT (Australian Capital Territory): Within 28 days of settlement.
• NT (Northern Territory): Within 60 days of the transaction or at settlement, whichever is earlier.

And here's why having to pay that extra cost immediately matters. If you've saved $60,000 toward a $600,000 property (a 10% deposit in NSW), you then need an additional $21,529 in stamp duty. So you actually need around $81,529 in total cash to proceed with a sale. That's a meaningful recalculation and could mean the different between whether you can affort a property, or not.

It affects your loan-to-value ratio

This can also impact your LVR (loan-to-value ratio) as how much you're borrowing compared to the property value might change because that extra money has to come from somewhere. That stamp duty now reduces the cash available from your savings but doesn't reduce the loan amount you need — which means it can quietly push your effective LVR higher than you planned, potentially triggering a requirement for Lenders Mortgage Insurance (LMI), and no longer being eligible for more favourable home loans.

Example: You've saved $90,000 and are purchasing a $700,000 property. You planned a $70,000 deposit (10% LVR) with a $20,000 buffer. If your stamp duty as a non-first home buyer in NSW is approximately $26,000, you're left with only $64,000 for the deposit — pushing your LVR above 90% and exposing you to LMI costs you didn't anticipate.

It determines your true price ceiling

Knowing the stamp duty for your target price range therefore helps you set a real, usable budget, and helps you avoid unexpected bills and surprises. You might find that a property at $750,000 tips you over your available cash when stamp duty is added, but a property at $680,000 is entirely achievable. Doing this calculation before you start inspections — not after you've made an emotional connection to a property — saves real heartache.

The difference between qualifying and not qualifying is substantial

As the NSW first home buyer example showed, the gap between qualifying for a concession and not qualifying can be $20,000 or more on a typical purchase. Knowing your status, and the threshold in your state, directly shapes which properties you target.

Key Terms

Transfer duty: The formal name used in most Australian states for what is commonly called stamp duty. Both terms refer to the same tax.

Dutiable value: The value on which stamp duty is calculated — the greater of the purchase price or the independently assessed market value at the time of transfer.

Concession: A reduction in stamp duty, typically applied to first home buyers, owner-occupiers, or certain property types below defined price thresholds.

Exemption: A full waiver of stamp duty for qualifying circumstances — such as eligible first home buyer purchases below a state threshold.

Settlement: The legal completion of a property sale, at which ownership formally transfers from seller to buyer. Stamp duty is due at or before settlement.

Principal place of residence (PPR): The property you live in as your primary home. Most first home buyer concessions require this condition to be met.

Lenders Mortgage Insurance (LMI): Insurance protecting the lender — not you — when your LVR exceeds 80%. Stamp duty's draw on your savings can unexpectedly push your LVR into LMI territory.

Foreign purchaser additional duty (FPAD): A surcharge applied on top of standard stamp duty in most states for buyers who are not Australian citizens or permanent residents.

Next Steps

Stamp duty is a significant cost, but it's a manageable one — as long as you plan for it before you start making offers. You now understand what it is, how it's calculated, why your state matters so much, and how it directly affects the deposit you need to have ready at settlement. Going in informed means no surprises on settlement day.

Key Takeaways

• Stamp duty is a state and territory government tax paid by the buyer every time a property changes hands
• Rates are progressive and tiered — the more expensive the property, the higher the effective rate
• Every Australian state and territory has its own rates, thresholds, and concessions — there is no single national rate
• First home buyers can save tens of thousands of dollars through state-based exemptions, but you must apply and must be purchasing your principal place of residence
• Stamp duty is almost always paid in cash at settlement — it cannot be rolled into your home loan
• Not accounting for stamp duty early can push your LVR higher than intended and trigger unexpected LMI costs

Know your number before you make an offer

The best way to understand your exact stamp duty obligation is to calculate it for your specific combination of state, purchase price, and buyer type.
