On Tuesday night the Treasurer handed down the biggest property tax reform in over a decade. In fact, the moment Chalmers mentioned "Capital Gains & negative gearing", my clients started messaging me.

The speech said it was about helping young Australians into the market by reining in tax breaks for property investors. That made a great headline! But it doesn't survive a careful read of the fine print.

The new rules contain so many grandfathering and exemption clauses that the actual people they are going to hit are not the people that the speech named. They land squarely on the next generation of investors trying to enter the market, not the existing investor portfolios the government framed as the problem. There is one part of the reform that does make genuine economic sense, and it is the part that gets the least attention.

Let's dive a bit deeper.

Budget 2026 in seven dot points

  • 50% CGT discount scrapped from 1 July 2027 and replaced with an inflation-adjustment model plus a 30% minimum tax on net capital gains.
  • Negative gearing restricted to new builds from 1 July 2027. Losses on established property cannot offset salary income.
  • Grandfathering rules: negative gearing on pre-budget properties is grandfathered forever. CGT works differently. Gains accrued before 1 July 2027 keep the 50% discount (for everyone). Gains accrued after fall under the new regime. Properties held across the cutoff are split at the asset's 1 July 2027 value.
  • SMSF and super funds exempt. Inside super the existing CGT discount and rules around limited recourse borrowing are untouched.
  • Affordable and government housing exempt. Typically delivered by community housing providers and managed funds (not a retail investor scheme outside of NDIS SDA).
  • New builds get a sweetener. Investors in new builds can choose either the 50% discount or the inflation model, whichever works in their favour.
  • $2 billion housing infrastructure package plus $500m for planning approvals. The government projects 75,000 additional home owners as a forecast outcome of the reforms, not a separate scheme.

What is actually changing

From 1 July 2027 the two pillars of property investor tax treatment in Australia are being reshaped. The first is capital gains tax. The 50% discount on capital gains for assets held more than twelve months has been the headline tax break for residential property investors since 1999. From 1 July 2027 it is being replaced with an inflation-adjustment model. You only pay tax on the gain above inflation, calculated by indexing the cost base. On that taxable gain, the rate is the higher of your marginal tax rate or 30%. So a 45% marginal earner still pays 45% (no change in effective rate from today). A 19% marginal earner now pays 30%, not 19%. The 30% is a floor on the effective rate, not an extra tax added on top.

The second is negative gearing. From 1 July 2027 you can only negatively gear a newly built residential property. Rental losses on established stock cannot be deducted against other income such as salary. Unused losses are ring-fenced to rental income or capital gains from residential property and can be carried forward.

What counts as a "new build"

Worth getting this right, because the difference between a "new" and "established" property is what now decides your tax position. The Treasury fact sheet specifies four categories that qualify:

Both reforms are large structural changes. Both have lead times. Both are wrapped in transitional rules and carve-outs that change who actually feels them.

Pending legislation

None of this is law yet. The Treasury has announced the rules and proposed the start dates. The bills still need to pass parliament, which requires negotiation with the Senate crossbench. Final legislation may differ from announced measures.

The grandfathering reality

The single most important detail in the Treasury fact sheet is the grandfathering rule. It does different things for the two reforms though, so it's worth getting straight.

Negative gearing is grandfathered by purchase date. If you owned an investment property at 7.30pm AEST on Tuesday 12 May 2026, including contracts signed before that time with later settlement, full negative gearing continues on that property for the life of the asset. Nothing changes.

Capital gains tax works differently. The new regime is structured around the date a capital gain accrues, not the date you bought the property. All capital gains accrued before 1 July 2027 keep the 50% discount, no matter when you bought. All gains accrued from 1 July 2027 onwards fall under the new inflation model and 30% minimum tax, also no matter when you bought. For property held across the 1 July 2027 cutoff, the gain at sale is split, using the asset's market value at 1 July 2027 (either a formal valuation or an ATO formula) as the bridge between the two regimes.

One of my clients owns three established properties across Brisbane and Melbourne, bought between 2018 and 2024. His negative gearing position doesn't change by a single dollar, ever. On CGT, his capital gain accrued up to 1 July 2027 is locked in at the 50% discount. Anything that accrues from that date forward, even on those long-held properties, falls under the new regime. Still a far better position than someone buying established property today and selling well after 2027.

That matters because of who actually owns established investment property in Australia. ATO data puts the figure at 2.24 million Australians, or roughly one in five taxpayers. Most of them are not corporate landlords or property barons. Most own a single investment property. The people who own multiple established investment properties, including the larger established portfolios the government's framing referenced, are the people whose negative gearing is grandfathered in full and whose existing CGT position is largely preserved.

The reform does not redistribute tax away from existing established-property portfolios in any deep way. It primarily changes the rules for new investors who haven't bought yet.

That is a very different policy to the one the speech described.

What about Super and SMSF

I've been getting questions from clients about this non stop for the past week and the answer is clear and important.

The Treasury fact sheet explicitly carves super out of both the CGT changes and the negative gearing changes. This is a direct quote of the rules, not commentary. Property held inside a superannuation fund, including a self-managed super fund, is completely exempt from both the CGT changes and the negative gearing changes. The 33.33% CGT discount inside super continues. The 15% concessional tax rate continues. Limited recourse borrowing arrangements for SMSF property are untouched.

For the rapidly growing number of Australians using their SMSF to hold residential property as part of a retirement strategy, nothing about the Budget changes the playbook. The same tax position applies, the same strategies work, and the same rules around timing and contributions stay where they are.

Side note · SMSF in retirement

Under ATO Exempt Current Pension Income rules, selling an SMSF property in retirement can mean zero CGT. The rules around timing and structure are specific. Speak to a licensed SMSF specialist.

$1.07T
Sits in Australian self-managed super funds (ATO SMSF statistics, September 2025). 661,000 SMSFs. Fastest-growing cohort is Australians aged 35 to 44. The Budget did not touch this corner of the market.

The other carve-outs

Beyond grandfathering and super, the Budget carves out:

Between grandfathering and these carve-outs, the surface area of the reform shrinks dramatically. What remains is a tax change that lands on Australians who buy established residential investment property from 12 May 2026 onwards, and only really bites from 1 July 2027.

One related measure — discretionary trusts

Separate from the CGT and negative gearing changes, the Budget also announced that from 1 July 2028, discretionary trusts will be taxed at a flat 30% on their taxable income, paid by the trustee. Fixed trusts, special disability trusts and charitable trusts are not affected. For property investors who hold investment property through a discretionary (family) trust for income splitting or asset protection, this changes the maths on those structures. Worth a chat with your accountant before the start date.

So who actually pays

The honest answer is new investors of established stock. People who don't already own an investment property, who plan to buy one after budget night, and who choose an established home rather than a new build. That cohort skews younger, not older. It is people building wealth, not people who have already built it.

The 75,000 figure the government has been quoting is a forecast of how many more Australians might become home owners as a result of reduced investor competition. It is a projection, not a program, and it depends entirely on real investor behaviour. There is no new buyer scheme, grant or incentive attached to it. If investors decide they're still going to compete for the same established stock (and many will), the projection won't land.

The framing of "tax the asset owners to fund first home buyers" sounds intuitively fair and makes a great headline. BUT the fine print delivers something vastly different. It actually does the exact opposite by exempting the existing owners and instead puts more taxes on the next generation of asset owners.

The one part that actually makes sense

There is one piece of the reform I think is structurally sound, and it is the part the speech downplayed: the channelling of investor activity toward new builds. Australia is short around 232,000 homes against demand over the last five years (we wrote about it last week in The Housing Gap). Anything that nudges investor capital toward building new dwellings rather than bidding up existing ones is a supply-positive policy.

By preserving negative gearing on new builds and giving them the choice between the old and new CGT regimes, the Budget creates a clear tax preference for new construction. The $2 billion local housing infrastructure package and $500m approvals fund support the same goal. If it works, more new dwellings get built. More supply closes the demand-supply gap that has driven prices and rents.

That part I'm in favour of. The framing around "taxing the elderly to help the young" I am not, because the rules don't really do that.

What investors should actually do

If you already own investment property at budget night, take a breath. Your portfolio is grandfathered. Nothing changes for you on those holdings, full stop. The strategy you used to buy them still works for them.

If you are thinking about your next investment property, here is the practical map.

Buy new, not established.

New builds keep both negative gearing and the choice between the 50% CGT discount and the inflation model. That is the most tax-favoured position in the post-1-July-2027 system, and it lines up with the message we have always given investors who don't have the capacity to develop or renovate. Buy new. Get all the tax benefits you can.

Consider the SMSF angle.

If you have the super balance to support it, SMSF property remains fully outside the new tax regime. The CGT discount inside super stays. The borrowing rules stay. For the right investor with the right structure, this is now a relatively more attractive corner of the market. Always with licensed financial advice.

Use the 14-month window thoughtfully.

If you do buy an established property between budget night and 1 July 2027, the 50% discount applies to gains accrued in that window. From 1 July 2027 the inflation model and 30% floor kick in. That is a hybrid outcome, not a permanent lock-in. The window has a real but limited value.

Watch the supply side.

The Budget puts a tailwind under new construction. That favours regions where developers are actually building (Perth, South-East Queensland, parts of regional NSW and Victoria). Different markets cycle at different times. The places adding stock are where investor activity will follow.

The bottom line

Read the fine print before reading the headline. The grandfathering rules do most of the work in this Budget. Negative gearing is fully grandfathered for existing investors, forever. The 50% CGT discount is locked in on every gain accrued up to 1 July 2027 for everyone holding before then. From that date forward, the new CGT regime applies to subsequent gains for everyone. SMSF and super stay where they are. Affordable housing gets a clear lane. The reform really bites on new investors of established stock, from a year and seven weeks from now.

For everyone else, the smart move hasn't really changed. New builds remain the most tax-efficient way for a retail investor to hold residential property, and that has been our standing advice for clients who don't have the capacity to develop or renovate. Budget 2026 has just made it more so.

Frequently asked questions

When do the Budget 2026 CGT and negative gearing changes start?
1 July 2027. The Budget was handed down at 7.30pm AEST on 12 May 2026, but the new rules only apply to gains arising and rental losses incurred from 1 July 2027 onwards.
Are existing property investors affected?
Yes and no. On negative gearing, existing investors are fully grandfathered: anyone who owned an investment property at 7.30pm AEST 12 May 2026 keeps full negative gearing on that property for the life of the asset. On CGT it's different: the 50% discount continues to apply to all gains accrued up to 1 July 2027, but the new inflation model and 30% minimum tax apply to any gain accrued from 1 July 2027 onwards. Properties held across the cutoff are split, using the asset's market value at 1 July 2027 as the bridge between the two regimes.
Does the Budget change how SMSFs invest in property?
No. The Treasury fact sheet explicitly carves out super funds, including self-managed super funds, from both the CGT and negative gearing changes. The 33.33% CGT discount inside super stays. The 15% concessional rate stays. Rules around limited recourse borrowing for SMSF property are unaffected.
What is the new CGT regime from 1 July 2027?
The 50% capital gains tax discount is being replaced with an inflation-adjustment model (you only pay CGT on the real gain above inflation) plus a 30% minimum tax on net capital gains. Investors in new builds can choose either regime, whichever produces a better outcome.
Can I still negatively gear an investment property after 1 July 2027?
Yes if it's a newly built residential property, or it was owned before budget night, or it's held in a super fund or supports a government affordable housing program. Other investors buying established property after budget night can only offset rental losses against rental income or capital gains from residential property from 1 July 2027 onwards.
What does the 75,000 home owners figure mean?
It's the government's forecast of how many additional Australians will become home owners as a result of reduced investor competition. It's a projection, not a new scheme, grant or program. Whether it materialises depends on real investor behaviour.
