This guide offers stamp duty NSW explained in plain terms, so you can see how transfer duty works before you buy. In New South Wales it is charged on a sliding scale based on the dutiable value of the property, so the amount rises with the value. Use our stamp duty calculator to estimate your potential costs before you buy.
Below, we cover how the rates are structured, walk through the calculation step by step, show how the first home buyer exemption changes the result and explain how to test your own numbers.
TL;DR Summary
- Stamp duty in NSW is officially called transfer duty and is based on the higher of the purchase price and market value.
- Duty uses a sliding scale of six brackets, and each rate applies only to the slice of value within that bracket.
- Many home purchases fall in the 4.5% bracket.
- Eligible first home buyers may pay no duty up to the scheme’s exemption threshold, with a reduced rate above it.
- Foreign purchasers may pay a 9% surcharge on top.
- Thresholds are indexed each 1 July, so always use current figures.
What Is Stamp Duty in NSW?
Stamp duty is the common name for transfer duty, a state tax paid when property ownership changes hands. Revenue NSW administers it, and it applies to houses, units and land. Owner-occupiers and investors pay the same general rates.
How Dutiable Value Works
Duty is calculated on the dutiable value, which is the higher of the agreed purchase price and the property’s market value. At an arm’s length sale, such as an auction, the price usually reflects market value. If a property is sold to a relative below market value, Revenue NSW may require a valuation.
When Transfer Duty Is Paid
Transfer duty is a one-off tax, not an annual charge. It is assessed once, on the contract or transfer, and does not recur. Your solicitor or conveyancer normally arranges payment to Revenue NSW around settlement.
How Transfer Duty NSW Rates Are Structured
Rates and thresholds are adjusted each year in line with CPI, and the rate year is set by your contract date. For 2026-27, NSW uses six brackets. Each bracket has a base amount that covers all lower brackets, plus a marginal rate on the portion of value above the bracket’s starting point.
| Bracket | Marginal rate | Where it applies |
|---|---|---|
| Bracket 1 | 1.25% | Very low dutiable values |
| Bracket 2 | 1.50% | Low dutiable values |
| Bracket 3 | 1.75% | Lower mid-range values |
| Bracket 4 | 3.50% | Mid-range values |
| Bracket 5 | 4.50% | The widest band, covering many home purchases |
| Bracket 6 | 5.50% | Higher dutiable values |
Above the premium threshold, residential property is charged at a marginal rate of 7%.
How to Calculate Stamp Duty in NSW
The calculation follows the same steps for every property:
- Confirm the dutiable value, which is the higher of the purchase price and market value.
- Find the bracket that contains that value.
- Take the base amount published for that bracket.
- Apply the marginal rate to the part of the value above the bracket’s starting point.
- Add the base amount and the result to get general transfer duty.
Why the Sliding Scale Matters
Because each rate applies only to the slice within its bracket, duty rises gradually rather than jumping at a threshold. A higher value does not make the entire amount subject to the top rate. Only the portion above each starting point is charged at the higher marginal rate.
A Worked Example in Words
Take a purchase with a dutiable value in the fifth bracket. You would look up that bracket’s base amount, work out how far the value sits above the bracket’s starting point and multiply that portion by 4.5%. Adding the two gives the general duty. The same method applies in every bracket, and only the base amount and marginal rate change.
How Duty Changes in Common Situations
General duty is the starting point, but your circumstances can change how it is assessed. The table summarises the most common situations.
| Situation | How duty is assessed |
|---|---|
| Eligible first home buyer, at or below the exemption threshold | No transfer duty |
| Eligible first home buyer, between the thresholds | Reduced duty that tapers as value rises |
| Eligible first home buyer, above the upper limit | General rates apply |
| Foreign purchaser | General duty plus a 9% surcharge on the dutiable value |
| Premium residential property | Premium rate applies above the premium threshold |
Foreign Purchasers
Foreign persons buying residential property in NSW may pay surcharge purchaser duty of 9% of the dutiable value, in addition to transfer duty, unless an exemption applies. This surcharge is a flat rate, unlike the sliding scale used for general duty.
Market Value Above the Price
If a property is sold for less than market value, for example in a family transfer, duty is charged on market value. Revenue NSW may ask for a valuation to confirm it.
First Home Buyer Exemption in NSW
The first home buyer exemption comes from the First Home Buyers Assistance Scheme. If you qualify, you pay no transfer duty on a new or existing home valued at or below the scheme’s exemption threshold. A separate, lower threshold applies to vacant land.
A reduced rate applies between the exemption threshold and an upper limit, and the concession tapers as the value rises until it reaches zero. Above the upper limit, general rates apply.
Eligibility conditions apply, including requirements about how you will occupy the property, and thresholds can be updated by government. Confirm your position with Revenue NSW before relying on the exemption.
Common Mistakes When Estimating Duty
A few errors cause most estimation problems:
- Using last year’s rates. Thresholds change every 1 July, so older figures can be out of date.
- Forgetting the market value rule. If market value exceeds the price, duty follows market value.
- Assuming an exemption applies. The first home buyer exemption depends on eligibility and on the property value.
- Applying the top rate to the whole value. Rates apply to the portion within each bracket, not the full amount.
- Treating an estimate as final. Calculators give guidance, and your conveyancer confirms the amount with Revenue NSW.
Where Stamp Duty Fits in the Buying Process
Transfer duty is assessed on the transfer of property, so it sits alongside the contract and settlement steps. The contract date sets the rate year, which matters if a purchase spans 1 July. Your solicitor or conveyancer confirms the dutiable value and arranges payment as part of settlement.
For eligible first home buyers, a small change in value near a threshold can noticeably change the duty position. Checking duty at several values before you make an offer helps you understand where a property sits.
Test Your Numbers With a Stamp Duty Calculator
Worked examples help, but most buyers compare several properties. Our stamp duty calculator lets you enter a purchase price and see an estimate based on current NSW rates, which makes it easier to compare properties side by side.
Treat the result as an estimate. Your solicitor or conveyancer confirms the final figure with Revenue NSW, and any exemption depends on your eligibility.
Final Thoughts
Stamp duty in NSW follows a clear method once you know the dutiable value and the current bracket. Working through the steps early helps you understand how exemptions apply and avoid surprises at settlement.
