Last night, Treasurer Jim Chalmers handed down what he described as “the most important and ambitious Budget in decades.” For NSW property, that wasn’t an overstatement. The 2026-27 Federal Budget delivers the most significant tax reform to the housing market in a generation, and the design of those reforms creates a clear, deliberate advantage for one type of property above all others: a brand-new home.
For Clarendon customers, that’s a meaningful moment. Whether you're looking at a house and land package in Sydney or regional NSW, or a knock down rebuild on the block you already love, you’re now building the most tax-advantaged asset class in the country. Here’s exactly what changed, and what it means for both pathways.
The headline: negative gearing now only applies to new builds
From July 2027, negative gearing for residential property will be limited to new builds.
Properties owned at the time of the budget are now grandfathered. Existing investors keep their current arrangements, but any investors buying established housing from now on will lose the ability to deduct rental losses against their wage or salary income. Losses can still be carried forward against future property income, but the immediate tax shelter that has driven so much investor demand for older homes is now gone.
The carve out for new builds is total. If you buy or build a new home as an investment, you keep full negative gearing, exactly as it works today.
This isn’t a loophole, it’s the explicit policy intent. The Treasurer’s briefing made the rationale plain. 83% of new investor loans in 2025 were for existing properties, which adds zero new dwellings to a market that desperately needs supply.
The CGT change, and an even better deal for new build investors
From the same date, the 50% capital gains tax discount will be replaced with inflation linked indexation plus a new minimum 30% tax rate on capital gains, applying only to gains arising after 1 July 2027.
Here’s the part that most initial reporting has glossed over, investors in new housing can choose. When you sell a newly built investment property, you’ll be able to elect either the old 50% CGT discount or the new indexation method, whichever gives you the best outcome. Investors in establish housing don’t get that choice.
So under the new regime, a new build investor in NSW keeps:
-
Full negative gearing
-
Choice between the old 50% CGT discount or the new indexation method
-
All existing depreciation benefits on a brand new assets.
This is the single largest structural advantage new construction has ever held over established property in the Australian tax system.
What this means for Clarendon customers
The new tax settings reshape both ends of the Clarendon customer journey, but in different ways.
House and Land
Clarendon currently has house and land packages available across 41 suburbs spanning Sydney's North West, South West and Western Sydney growth corridors, the Hunter and Newcastle, the Illawarra, the South Coast and the Southern Highlands. That breadth matters more than it ever has under the new tax settings because the policy advantage attaches to the new dwelling itself, the real question for buyers isn't whether to build new, but where.
And the where has rarely been more compelling. The Western Sydney International Airport opens later this year. The Sydney Metro Western Sydney Airport line is progressing toward connecting St Marys to the Aerotropolis. The South West Metro extension is tracking for the second half of 2026. Federal and state governments together have committed over $28 billion in enabling infrastructure across Western Sydney, with private development proposals worth close to $33 billion in the Aerotropolis alone.
Beyond Sydney, the Hunter, Illawarra, South Coast and Highlands offer something the metro corridors can't always match - lower entry prices, strong rental yields, and lifestyle locations that have been quietly outperforming on growth. For an investor working out where the new tax settings stretch furthest, the regional Clarendon packages reward a closer look.
Knockdown rebuild
For homeowners in Sydney's established suburbs, knock down rebuild has always been a way to get the home you actually want on the land you already love without surrendering your school catchment, your commute, or your neighbourhood.
After this budget, it's also the answer for any homeowner who's been weighing up renovate vs rebuild. A knock down rebuild creates a brand new dwelling on your existing block. For owner-occupiers, that means stepping into a home built to current standards that are energy efficiency, have modern layouts and are smart-home ready, all backed by all the supply-side measures the budget puts behind new construction.
For investor-owners considering rebuilding a tired investment property, the new dwelling status of a knock down rebuild aligns it with the new-build category that the tax reforms favour. The specifics of how the new rules will treat individual rebuild scenarios will be confirmed when the legislation is drafted, but the policy direction is unambiguous: new dwellings are where the system is steering investor capital.
As Sydney's leading knock down rebuild builder, Clarendon has been having these conversations with homeowners for decades. The 2026 budget just gave a lot more of them a reason to start now.
The bottom line for NSW
This budget isn't subtle. The government has openly designed the new tax system to push capital out of bidding wars over older homes and into the construction of new ones. For NSW the largest, most investor-heavy property market in the country, that's a fundamental rewrite of the playing field.
A new home built in NSW today is now the most tax-advantaged residential property asset in Australia. That applies whether your new home rises on a house and land block in a Sydney growth corridor, or on the slab where your existing home stood yesterday.
For almost 48 years, Clarendon Homes has built across both pathways - house and land for buyers chasing space and value in NSW's growth corridors, and knock down rebuild for homeowners who'd rather upgrade than move. After last night, both of those decisions are easier to make.
