How Stamp Duty Works in Australia
Stamp duty, officially known as transfer duty, is a state and territory government tax charged on property purchases in Australia. It is one of the largest upfront costs of buying a home, typically ranging from 1% to 5.5% of the property's value depending on the state and price. According to the Australian Bureau of Statistics (ABS), state and territory governments collectively collected approximately AUD 30 billion in stamp duty in the 2023-24 financial year, making it their single largest revenue source after GST distributions.
Unlike ongoing taxes such as land tax or council rates, stamp duty is a one-off payment made at or before settlement. It is calculated on the property's purchase price or market value (whichever is higher) using progressive tiered rates set by each state's revenue office. First home buyers can access significant concessions or full exemptions depending on their state and the property value. You can estimate your overall Australian tax position with our Australia Income Tax Calculator and plan for retirement using the Superannuation Calculator.
How Stamp Duty Is Calculated
Each state uses a progressive tiered system defined by its state revenue office. The formula applies marginal rates to portions of the property value within each tier:
Total Duty = Sum of (Value in each tier x Rate for that tier)
Worked example for a A$750,000 property in NSW (non-first-home buyer):
- First A$100,000 at 1.25% = A$1,250
- A$100,001 - A$300,000 at 1.5% = A$3,000
- A$300,001 - A$750,000 at 1.75% = A$7,875
- Total stamp duty: approximately A$12,125
- Effective rate: 1.62% of purchase price
Key Terms You Should Know
- Transfer Duty: The official name for stamp duty in most states. A one-off tax paid when property ownership is transferred.
- First Home Buyer (FHB) Concession: Reduced or zero stamp duty for eligible first-time property purchasers. Thresholds and rules vary by state.
- Foreign Purchaser Surcharge: An additional duty of 7-8% charged on top of standard stamp duty for foreign buyers in most states (e.g., 8% in NSW, 8% in VIC).
- Dutiable Value: The higher of the purchase price or market value, which forms the base for calculating stamp duty.
- Off-the-Plan Concession: Some states offer reduced stamp duty for off-the-plan apartment purchases, calculated on the land value rather than the completed value.
Stamp Duty Rates by State: First Home Buyer Exemptions
The following table compares first home buyer stamp duty exemption thresholds across all states and territories, based on data from each state's revenue office. According to ABS data, the median house price in Australia was approximately A$880,000 in Q4 2024, meaning many first home buyers in expensive states exceed the exemption threshold.
| State/Territory | FHB Exemption Threshold | Top Marginal Rate | Foreign Surcharge |
|---|---|---|---|
| NSW | A$800,000 | 4.5% | 8% |
| VIC | A$600,000 | 5.5% | 8% |
| QLD | A$550,000 (concession) | 4.5% | 7% |
| SA | A$650,000 | 5.5% | 7% |
| WA | A$530,000 | 5.15% | 7% |
| TAS | 50% discount | 4.5% | 8% |
| NT | A$650,000 | 5.9% | None |
| ACT | A$600,000 | 6% | None |
Practical Examples
Example 1: First home buyer purchasing a A$650,000 apartment in Victoria. VIC exempts properties up to A$600,000 for FHBs, with a sliding scale up to A$750,000. At A$650,000, the buyer receives a partial concession. Standard duty would be approximately A$24,870; the concession reduces this to approximately A$12,435. Savings: A$12,435 compared to a non-FHB buyer.
Example 2: Investor buying a A$1,200,000 house in Queensland. QLD duty on A$1,200,000: approximately A$43,525 (no FHB concession for investors). This represents about 3.6% of the purchase price. If the buyer is a foreign purchaser, an additional 7% surcharge (A$84,000) applies, bringing total duty to approximately A$127,525. Use our Mortgage Calculator to factor stamp duty into total purchasing costs.
Example 3: First home buyer purchasing a A$700,000 home in NSW. NSW fully exempts FHBs on properties up to A$800,000, so stamp duty is A$0. Without the exemption, duty would be approximately A$6,125. This buyer also qualifies for the First Home Owner Grant (FHOG) of A$10,000 for new homes. The combined savings of A$16,125 significantly reduces upfront costs.
Tips to Reduce Your Stamp Duty
- Check first home buyer eligibility: Even if you have owned property overseas, you may still qualify as a first home buyer in some Australian states. Each state has different definitions, so check with your state revenue office.
- Consider off-the-plan purchases: Some states calculate stamp duty for off-the-plan properties on the land value at contract date rather than the completed property value, potentially saving tens of thousands.
- Buy below the exemption threshold: If possible, negotiate the purchase price to stay within your state's FHB exemption threshold. In NSW, buying at A$800,000 vs. A$810,000 can mean a difference of thousands in duty.
- Check for pensioner and concession holder discounts: Some states offer reduced rates for pensioners, concession card holders, or purchases of vacant land for building a home.
- Budget for stamp duty separately: While some lenders allow capitalising stamp duty into the loan, this adds interest costs over the life of the mortgage. Saving the duty amount separately keeps your LVR lower and may help avoid Lenders Mortgage Insurance.
2025 Updates and Recent Changes
Several states have recently modified their stamp duty policies. NSW raised the first home buyer exemption threshold to A$800,000 in 2023 and introduced an optional annual property tax as an alternative to stamp duty for properties up to A$1.5 million. Victoria's FHB concession threshold remains at A$600,000, though the state also offers a shared equity scheme. The ACT continues its multi-decade transition from stamp duty to higher annual land rates, with ACT duty rates decreasing each year. According to the Parliamentary Budget Office, Australia collects more in property transfer taxes as a share of GDP than any other OECD country, at approximately 1.3% of GDP. National debate continues about whether stamp duty should be replaced by a broad-based land tax to improve housing affordability and labor mobility.
Frequently Asked Questions
What is stamp duty in Australia?
Stamp duty (transfer duty) is a state and territory government tax charged when you purchase property in Australia. It is a one-off payment typically required at or before settlement. The amount depends on the property's purchase price or market value, the state or territory, whether you are a first home buyer, and whether you are a foreign purchaser. Stamp duty is calculated using progressive tiered rates, similar to income tax brackets, where higher portions of the property value attract higher rates. According to ABS data, Australian states collectively collected approximately A$30 billion in stamp duty revenue in 2023-24.
Do first home buyers pay stamp duty in Australia?
Most states offer stamp duty exemptions or concessions for eligible first home buyers. NSW provides a full exemption for properties up to A$800,000, with a sliding scale up to A$1,000,000. Victoria exempts properties up to A$600,000 with concessions up to A$750,000. Queensland offers concessions for homes valued up to A$550,000. South Australia exempts up to A$650,000, and WA exempts up to A$530,000. Eligibility typically requires being over 18, an Australian citizen or permanent resident, having never owned property in Australia, and intending to live in the property. Thresholds and rules are updated periodically by each state.
Can I add stamp duty to my mortgage?
Some lenders allow you to capitalise (add) stamp duty to your home loan, but this is generally not recommended. Adding A$30,000 in stamp duty to a 30-year mortgage at 6% interest costs approximately A$34,740 in additional interest over the loan term, bringing the true cost to A$64,740. It may also push your loan-to-value ratio (LVR) above 80%, triggering Lenders Mortgage Insurance (LMI) which can add thousands more. If you must capitalise, ensure you factor the true cost including compounding interest. Most financial advisors recommend saving for stamp duty separately alongside your deposit.
Is the ACT replacing stamp duty with a land tax?
Yes, the ACT is the only Australian jurisdiction progressively abolishing stamp duty, replacing it with higher annual land tax (general rates). This transition began in 2012 and is expected to take approximately 20 years. During the transition, ACT stamp duty rates are being reduced each year while annual rates increase. The rationale is that annual land tax is more economically efficient than stamp duty because it does not discourage property transactions. Several economists and think tanks have advocated for other states to follow the ACT model, arguing it would improve housing affordability and labor market mobility.
What is the foreign purchaser stamp duty surcharge?
Most Australian states levy an additional stamp duty surcharge on foreign purchasers (non-citizens and non-permanent residents). As of 2025, the surcharges are: NSW 8%, VIC 8%, QLD 7%, SA 7%, WA 7%, and TAS 8%. The NT and ACT do not impose a surcharge. This surcharge is added on top of the standard stamp duty, significantly increasing the cost for foreign buyers. For example, a foreign buyer purchasing a A$1,000,000 property in NSW would pay approximately A$40,000 in standard duty plus A$80,000 in foreign surcharge, totaling A$120,000. Some bilateral tax treaties may provide exemptions.
How does NSW's property tax alternative work?
NSW introduced an optional annual property tax as an alternative to stamp duty for eligible properties (first home buyers purchasing homes valued up to A$1.5 million). Instead of paying a lump sum stamp duty at purchase, buyers can choose to pay an annual property tax of A$400 plus 0.3% of the land value. This removes the upfront barrier to homeownership but results in ongoing annual payments. The choice is irrevocable and attaches to the property for all future owners. For a property with A$500,000 land value, the annual tax would be A$1,900 compared to a one-off stamp duty of potentially A$20,000+. The breakeven point depends on the property value and how long you own the home.
