First Home Buyer Concessions

Every state offers some form of stamp duty relief for first home buyers, but the rules vary dramatically. Some states offer full exemptions up to certain thresholds, others use sliding scales, and one state (SA) only provides relief on new homes. Understanding your state's rules can save you tens of thousands of dollars.

Understanding the calculation

How Stamp Duty Is Calculated

Stamp duty uses progressive brackets — similar to income tax. You don't pay the top rate on the entire purchase price. Instead, each slice of the property value is taxed at an increasing rate. Here's exactly how the maths works.

Worked Example: $750,000 Existing Home in NSW

Owner-occupier, not a first home buyer. NSW uses 6 progressive brackets.

BracketRateAmount in BracketDuty
$0$17,0001.25%$17,000$213
$17,001$37,0001.50%$20,000$300
$37,001$99,0001.75%$62,000$1,085
$99,001$372,0003.50%$273,000$9,555
$372,001$1,240,0004.50%$378,000$17,010
$1,240,001$3,721,0005.50%
Total stamp duty$28,162

The effective rate is 3.75% — not the top marginal rate of 4.50%. On a $750,000 property in NSW, stamp duty of $28,162 adds 3.8% to your purchase cost. That's $28,162 you need on top of your deposit.

Same Property, 8 Different Bills

What Most Buyers Don't Realise

Four facts that can save you thousands — or cost you if you don't know them.

First home buyers

$28,162 saved

A first home buyer purchasing the same $750,000 property in NSW pays $0 instead of $28,162. That's a full exemption — $0 stamp duty.

Foreign buyers

Location matters

$20,862 gap

At $750,000, the cheapest state (Australian Capital Territory) charges $19,208 while the most expensive (Victoria) charges $40,070. Same price, very different cost.

Timing

Due at settlement

Stamp duty is paid when you settle — not when you sign the contract. Your conveyancer lodges it with the state revenue office. In most states you have 3 months from contract exchange, but late payment attracts interest and penalties.

Why Every State Is Different

Stamp duty is a state tax, not federal. Each state and territory sets its own rates, brackets, and concessions independently. Some states (like VIC) have separate rate schedules for owner-occupiers and investors. The NT uses a unique quadratic formula instead of brackets. The ACT is the only jurisdiction actively phasing out stamp duty, replacing it with higher annual land tax — though buyers during the transition period may effectively pay both.

The calculator above applies the correct schedule for your state automatically. If you're comparing properties across state borders, use the state comparison tool to see the full picture.
