Understanding Stamp Duty: Costs by State and Territory

When you're buying a property in Australia, stamp duty is one of the biggest costs you'll face at settlement—but understanding how much you'll actually pay depends entirely on which state or territory you're buying in. The good news? Armed with the right information, you can plan ahead and potentially save thousands of dollars.

What Is Stamp Duty?

Stamp duty (also called transfer duty) is a tax levied by state and territory governments when you purchase property. It's calculated based on the property's purchase price and varies significantly across Australia. Unlike other taxes, there's no single national rate—each state and territory sets its own thresholds and percentages, which means two identical properties could cost very different amounts in stamp duty depending on their location.

The duty is payable before settlement, so it's essential to factor this into your budget when making an offer on a property.

Stamp Duty Rates by State and Territory

New South Wales

NSW has a tiered stamp duty system that increases with property value. For properties between $300,001 and $1 million, you'll pay $8,990 plus $4.50 for every $100 (or part thereof) over $300,000. Premium properties worth $3 million and above attract stamp duty of $150,490 plus $7 for every $100 over $3 million, though this premium duty only applies to residential land.

First home buyers in NSW enjoy significant relief, with exemptions on properties valued up to $800,000.

Victoria

Victoria generally has Australia's highest transfer duties. For properties valued between $300,001 and $500,000, you'll pay $4,600 plus $3.40 per $100 (or part thereof) above $300,000. This increases to $11,400 plus $4.32 per $100 for properties between $500,001 and $750,000.

First home buyers receive exemptions on properties up to $600,000.

Queensland

Queensland offers some of Australia's lowest stamp duty rates. There's no duty on properties valued less than $5,000, and rates of 1.5% apply between $5,000 and $75,000. For properties between $75,000 and $540,000, you'll pay $1,050 plus $3.50 for every $100 over $75,000.

Queensland's first home buyer concessions are particularly generous, with exemptions on new homes and established properties up to $700,000. If you're purchasing a new home in Queensland, you may pay zero stamp duty regardless of price.

Western Australia

WA has Australia's lowest top marginal stamp duty rate at 5.15%. For properties worth $120,000 and below, the rate is 1.9%, increasing in increments to $28,435 plus 5.15% of dutiable value over $725,000.

Interestingly, WA doesn't offer stamp duty exemptions for first home buyers, though there are concessional rates available. For example, a $500,000 residential home in WA would cost approximately $17,765 in stamp duty.

South Australia

South Australia offers excellent value for first home buyers, with zero stamp duty on new homes with no price cap. This makes SA particularly attractive if you're building new. For established properties, first home buyers get exemptions up to $500,000 (or higher for new homes).

Tasmania

Tasmania provides first home buyer exemptions on properties valued up to $750,000, though this concession is scheduled to end in June 2026. It's worth checking the current status if you're planning to buy in Tasmania.

Australian Capital Territory

In the ACT, properties worth $200,000 and below incur duty of $20 or $1.48 per $100, whichever is greater. The rate increases with property value, reaching a flat rate of $5.09 per $100 (applied to the total transaction value) for properties worth $1,455,000 and above.

The ACT offers a unique unit exemption for first home buyers, providing relief on apartments and units valued up to $1.02 million.

Northern Territory

The NT doesn't currently offer first home buyer stamp duty exemptions. However, first home buyers may be eligible for a $50,000 grant instead.

Foreign Buyer Surcharges

If you're not an Australian citizen, be prepared for additional costs. Most states charge a foreign buyer surcharge on top of standard stamp duty:

• NSW: 8%
• Victoria: 8%
• Queensland: 8%
• Western Australia: 7%
• South Australia: 7%
• Tasmania: 8%
• ACT and NT: No foreign buyer surcharges currently apply

This surcharge is added on top of your standard stamp duty, so it can significantly increase your total settlement costs.

First Home Buyer Concessions

If you're a first home buyer, you may qualify for substantial stamp duty relief. The concessions vary considerably by state:

• NSW: $0 up to $800,000
• Victoria: $0 up to $600,000
• Queensland: $0 for new homes; $0 up to $700,000 for established properties
• Western Australia: $0 up to $500,000
• South Australia: $0 for new homes (no cap)
• Tasmania: $0 up to $750,000 (until June 2026)
• ACT: Unit exemption up to $1.02 million
• NT: No exemptions, but $50,000 grant available

These concessions can save you tens of thousands of dollars, so it's crucial to check whether you qualify and understand the specific eligibility criteria in your state.

Which State Has the Lowest Stamp Duty?

The answer depends on your property price and buyer status. Generally, Western Australia has Australia's lowest top marginal rate at 5.15%. However, for first home buyers specifically, South Australia and Queensland offer the most generous concessions, with zero stamp duty on new homes and no price caps in some cases.

Planning Ahead for Stamp Duty

When you're budgeting for a property purchase, stamp duty should be a significant line item. It's not just the purchase price you need to save for—you'll also need to cover conveyancing fees, building inspections, and stamp duty itself.

If you're in a position to choose between states, the stamp duty differences could justify the move. For example, buying a new home in South Australia could save you substantial stamp duty compared to purchasing an established property in Victoria at the same price point.

Take advantage of first home buyer concessions if you qualify. These are genuine government support programs designed to help you get into the property market, and missing out on them means leaving thousands of dollars on the table.

Next Steps

Before making an offer on a property, use an online stamp duty calculator specific to your state to understand your exact costs. If you're working with a conveyancer or mortgage broker, ask them to provide a detailed breakdown of all settlement costs, including stamp duty. This will give you a clear picture of how much you'll need to pay and help you plan your finances accordingly.
