State-by-state stamp duty changes proposed for 2027

Stamp duty is the largest single transaction cost in Australian property purchase. It is also one of the most disliked taxes by buyers and one of the most politically charged. Three states have announced or proposed reforms for 2027 that could materially shift the maths for buyers.

This post is the current status of the proposed reforms in 2026, with the dollar implications if each proceeds.

NSW: the property tax pilot

The NSW Government's first-home-buyer property-tax option (introduced as a pilot in 2023) lets eligible first home buyers replace the upfront stamp duty with an annual property tax. As of 2026 the pilot continues but take-up has been modest.

The current settings (2026)

• Available to first home buyers purchasing under $1.5M
• Upfront stamp duty waived
• Annual property tax of $400 + 0.3% of the land value
• The tax continues for as long as the buyer owns the property and meets eligibility
• The property reverts to standard stamp duty regime when sold to a non-first-home-buyer

The proposed 2027 changes

The NSW Treasury has been reviewing whether to:

1. Lift the eligibility threshold (currently $1.5M) to $2M, capturing more inner-Sydney first home buyers
2. Make the property-tax option available to all first home buyers, not just those in metro areas
3. Reduce the annual tax rate to 0.2% to improve attractiveness
4. Extend the option to investment property purchases (controversial; reduces state revenue)

The most likely 2027 outcomes:

• Threshold lift to $1.8M-$2M
• Possible rate reduction to 0.25%
• Investment property extension unlikely in this cycle

Implications for buyers

For a first home buyer purchasing a $1.4M property in 2026 under current settings:

• Property tax option saves $61,440 upfront (the stamp duty)
• Annual tax: $400 + 0.3% × $800,000 (land value) = $2,800/year
• Break-even with upfront stamp duty: approximately 22 years

For most first home buyers who plan to hold the property for less than 22 years, the property tax option saves money. For most who plan to hold longer, the upfront option is cheaper over the long term.

If the 2027 reforms reduce the rate to 0.25%, the break-even extends to approximately 26 years, making the property tax option more attractive for medium-term holders.

VIC: the threshold review

Victoria's stamp duty has the steepest curve of any Australian state for properties between $750k and $2M. The Victorian Treasury has flagged a review of the thresholds for 2027.

Current settings (2026)

• Up to $130,000: minimal rates
• $130,000 to $960,000: progressive rates peaking around 5.5%
• $960,000 to $2,000,000: 6.0% marginal rate
• Above $2,000,000 (premium): 6.5% with additional surcharge

Possible 2027 changes

The most likely review outcomes:

1. Smoothing the cliff at $960,000 (the 0.5% jump that catches mid-tier buyers)
2. Lifting the first home buyer concession threshold (currently $600,000 full exemption, $750,000 sliding) to reflect price growth
3. Reviewing the foreign investor surcharge (currently 8% on top of standard stamp duty)

Implications for buyers

If the $960,000 cliff is smoothed, the marginal rate at that price point drops by approximately 0.5%. On a $1.0M purchase the stamp duty saving is approximately $2,000-3,000.

If the first home buyer concession threshold is lifted, the population of eligible first home buyers expands materially, particularly in middle-Melbourne suburbs where prices have grown into the $700k-$850k range.

SA: pensioner concession expansion

South Australia has the most generous treatment for pensioner-first-home or downsizing-pensioner buyers among the states. The SA Government has proposed expanding the concession further in 2027.

Current settings (2026)

• Standard stamp duty applies to most purchases
• Pensioner concessions for buyers receiving Centrelink pensions, available up to $300,000-400,000 of property value
• First home buyer concessions for new builds

Possible 2027 changes

• Extending pensioner concessions to higher property values (up to $650,000-$700,000)
• Combining pensioner concessions with FHOG to allow stacking
• Introducing a downsizer concession for owner-occupiers selling a long-held PPOR and buying smaller

Implications for buyers

If the pensioner concession is extended to $650,000, the typical retiree downsizing from a $1.2M long-held home to a $550,000 retirement-suitable property saves $20,000-30,000 in stamp duty.

This category of buyer is growing rapidly as Australia's aging demographic moves through retirement transition. The reform addresses real demand.

Other states: status

Queensland

QLD increased its First Home Owner Grant to $30,000 for new builds in 2023. No major stamp duty reforms announced for 2027. The QLD Government has focused on supply-side measures (planning reform, infrastructure investment).

Western Australia

WA flattened its stamp duty curve in 2025. Further reforms not currently announced for 2027.

Tasmania, Northern Territory, ACT

Smaller states with their own dynamics. TAS has a long-running review of stamp duty equity. ACT has progressively moved residential stamp duty toward higher annual rates over the past decade. NT has the least reform activity.

What this means for 2026 buyers

Three implications:

Implication 1: timing matters

If you are buying in NSW as a first home buyer under $1.5M, the current property-tax option is available immediately. Waiting for 2027 reforms may improve the deal slightly but the wait carries opportunity cost.

For VIC buyers near the $960,000 cliff, waiting until 2027 may save $2-3k if the cliff is smoothed. The wait is probably not worth the broader market risk.

Implication 2: model multiple scenarios

For substantial purchases, model the cashflow under current and proposed settings. The difference can be meaningful but is rarely deal-determining.

Implication 3: do not over-react to political announcements

Reform proposals are common. Reform delivery is less common. Some 2027 proposals will land. Others will not. Build your decision on the current settings, not speculation about future reforms.

For buyers thinking 2-3 years ahead, the SafeBuy financial calculator models scenarios at current rates. The directional impact of proposed reforms can be assessed from the current numbers.

Stamp duty is the largest preventable transaction cost in Australian property. Knowing the current rules is essential. Watching for the announced reforms is helpful but not urgent. Most buyers will purchase under the rules that exist on the day they exchange, and those are the rules SafeBuy and your conveyancer compute against.
