Understanding Stamp Duty in Australia
Stamp duty, also known as transfer duty, is a state government tax levied when you purchase property in Australia. Each state and territory sets its own rates, thresholds, and concessions, which means the amount you pay can vary dramatically depending on where you buy. Stamp duty is typically calculated on a sliding scale — the higher the property value, the higher the percentage you pay on the portion above each threshold.
The duty is a one-off cost paid at settlement or within 30 to 90 days of the contract date, depending on the jurisdiction. It applies to residential and commercial properties, vacant land, and in some states, off-the-plan purchases. Understanding your stamp duty obligation early in the buying process is essential for accurate budgeting, as it can add tens of thousands of dollars to your purchase cost.
Stamp Duty Rates by State and Territory
New South Wales charges between 1.25% and 7% depending on property value, with first home buyers exempt on properties up to $800,000 under the First Home Buyer Assistance Scheme. Victoria uses rates from 1.4% to 6%, with a flat 5.5% applying to properties above $960,000, and first home buyer exemptions up to $600,000. Queensland starts with a 0% threshold on the first $5,000, rising to 5.75% above $1,000,000, with first home concessions up to $500,000.
Western Australia charges 1.9% to 6.625% with first home buyer exemptions up to $430,000. South Australia uses rates from 1% to 5.5% across nine brackets. Tasmania ranges from a minimum $50 fee to 4.5%, with a 50% discount for first home buyers on properties up to $400,000. The ACT uses a per-$100 formula, and the Northern Territory uses a quadratic formula that produces a smooth curve rather than sharp bracket jumps.
Example: $750,000 property in NSW (owner occupier)
- Property price: $750,000
- Stamp duty: $28,285
- Effective rate: 3.77%
- Total purchase cost: $778,285
First Home Buyer Concessions Across Australia
Every Australian state offers some form of stamp duty concession or exemption for eligible first home buyers. In NSW, properties valued at $800,000 or below are fully exempt, with a sliding concession up to $1,000,000. Victoria exempts first home buyers on properties up to $600,000 and offers a concession up to $750,000. Queensland provides a concession that phases out between $500,000 and $550,000.
Western Australia offers full exemption up to $430,000, with a tapered concession to $530,000. Tasmania gives first home buyers a 50% duty reduction on properties up to $400,000. The ACT and NT also provide concessions, though eligibility criteria vary. In most states, you must be an Australian citizen or permanent resident, have never owned property in Australia, and intend to live in the property as your primary residence for a minimum period — usually 6 to 12 months.
Tips to Reduce Your Stamp Duty
Consider buying below the first home buyer exemption threshold in your state to avoid stamp duty entirely. In NSW, a property at $800,000 attracts zero duty for a first home buyer, while one at $810,000 would cost thousands. Timing your purchase around budget announcements can also help, as state governments occasionally adjust thresholds or introduce temporary concessions.
Off-the-plan purchases may qualify for stamp duty savings in some states, as duty is calculated on the land value at the contract date rather than the completed property value. Vacant land can also attract lower duty than established homes. Foreign buyers should be aware of surcharges ranging from 2% to 8% depending on the state — these are in addition to standard duty rates and can significantly increase the total cost of purchase.
Frequently Asked Questions
What is stamp duty in Australia?
Stamp duty (also called transfer duty) is a state government tax paid when you purchase property. Each state and territory sets its own rates, so the amount depends on where you buy, the property value, and your buyer type. It is a one-off cost paid at or shortly after settlement.
Which state has the lowest stamp duty?
The Northern Territory and Queensland generally have the lowest stamp duty for properties under $500,000. For first home buyers, NSW offers full exemption up to $800,000, making it the most generous threshold. However, rates vary by price bracket, so the cheapest state depends on the specific property value.
Are first home buyers exempt from stamp duty?
Most states offer full or partial stamp duty exemptions for first home buyers. NSW exempts purchases up to $800,000, VIC up to $600,000, QLD up to $500,000, WA up to $430,000, and NT up to $650,000. TAS offers a 50% discount up to $400,000. Eligibility conditions include living in the property as your primary residence.
Do foreign buyers pay extra stamp duty?
Yes. All states charge a foreign buyer surcharge on top of standard stamp duty. The surcharge ranges from 3% in Tasmania to 8% in NSW and Victoria. For a $1,000,000 property in NSW, a foreign buyer would pay an additional $80,000 on top of the standard duty, significantly increasing the total cost.
Can I add stamp duty to my mortgage?
Most lenders do not allow you to add stamp duty directly to your home loan, as it pushes your loan-to-value ratio above standard limits. However, if you borrow more than the property price (with lenders mortgage insurance), the extra funds can cover stamp duty. This calculator shows the monthly cost if duty were added to your mortgage for comparison.
Is stamp duty the same as land tax?
No. Stamp duty is a one-off tax paid at the time of purchase. Land tax is an annual tax on the unimproved value of land, typically only applying to investment properties and second homes. Owner-occupied primary residences are usually exempt from land tax in all states.
