Understanding Property Tax Deductions When Buying a House

If you buy an established investment property after 7:30pm AEST on 12 May 2026, you will no longer be able to deduct rental losses from your salary. That single change, announced in the 2026 Federal Budget, rewrites the tax rulebook for Australian property investors. The government projects this will help 75,000 more first home buyers enter the market over the next decade, while slowing house price growth by roughly 2% over a couple of years. Whether you are buying your first home, upgrading, or adding to a portfolio, the way property tax deductions work has shifted in ways that affect cash flow, sale timing, and long-term returns.

Budget Papers

The budget is not just about investors. If you rent, the Treasury modelling suggests a minimal impact — less than $2 per week extra for a household paying median rent. For buyers, the picture is more mixed. First-home buyers may face less competition at lower price points, but investors are expected to pivot toward new builds, keeping that segment competitive. Here’s what you actually need to know.

Grandfathering protects existing owners
Properties bought or contracted before 7:30pm 12 May 2026 keep full negative gearing against salary until sold.

New builds get preferential treatment
Investors in new builds retain full negative gearing and can choose between the 50% CGT discount or indexation.

Established properties face ring-fencing
From 1 July 2027, losses on established properties bought after Budget night can only offset rental income or capital gains — not salary.

CGT discount replaced by indexation
The 50% CGT discount ends 1 July 2027. A CPI-indexed cost base applies, with a 30% minimum tax on net capital gains.

Let me define the central concept here because it matters for every section that follows. Negative gearing is when the costs of owning a rental property — mortgage interest, maintenance, management fees — exceed the rental income it generates. That loss has historically been deductible against your total income, including your salary. The 2026 Budget changes that for established properties bought after the cutoff. For new builds, nothing changes.

Negative Gearing
When property holding costs exceed rental income, creating a loss that can be offset against other income. From 1 July 2027, this offset is restricted to rental income and capital gains for established properties bought after 12 May 2026.

What I tend to notice is most people focus on the headline CGT change and miss the negative gearing detail, which actually hits cash flow much sooner. The strategies for first-time property investors that worked a year ago may no longer suit a post-Budget purchase.

Old Rules vs New Rules: The Full Cost Comparison

The most direct way to see what changed is to put the old and new systems side by side. The table below covers the four areas that matter most for anyone buying or selling property in Australia.

Trust distributionsNo minimum tax rate30% minimum tax on discretionary trust distributions from 1 July 2028

What this table does not show is the cash-flow effect. Under the old rules, an investor with a $20,000 yearly rental loss and a $100,000 salary could reduce taxable income to $80,000, saving thousands in tax each year. Under the new rules for established properties, that $20,000 loss is banked by the ATO and can only offset future rental income or the capital gain when you sell. The investor must fund the full $20,000 shortfall from their own pocket each year until the property turns cash-flow positive or they sell.

Grandfathering cutoff: 7:30pm AEST, 12 May 2026
If you exchanged contracts before this time, your property is fully protected under the old rules — regardless of when settlement happens. This is the single most important date in the entire reform.

For mortgage options on rural properties, the new build carve-out is especially relevant. Vacant land on which you construct a dwelling counts as a new build, meaning investors who buy rural land and build may still access full negative gearing and the choice of CGT method.

Common Misunderstandings About the Property Tax Changes

Mistaking the grandfathering date for the settlement date

The budget papers use the phrase “purchased or exchanged before 7:30pm AEST on 12 May 2026.” Some buyers assume that as long as they settle before 1 July 2027, they are safe. That is wrong. The cutoff is the exchange date — the moment you sign the contract. If you exchanged at 8pm on 12 May 2026, even if settlement is months away, the new rules apply to that property. The Dott & Crossitt budget guide confirms that properties under contract before the deadline are fully protected regardless of settlement timing.

Assuming all properties are treated the same way

A renovated or extended established property does not qualify as a new build. Only off-the-plan apartments, residential construction on vacant land, duplexes via knock-down rebuilds, and properties occupied less than 12 months before first sale count. If you buy a 1970s house, renovate the kitchen, and try to claim new-build status, you will be in for a surprise. The losses are still deductible — just not against your salary.

Thinking the 50% CGT discount survives indefinitely

For assets held across the 1 July 2027 transition, the gain is split. Any gain accrued up to that date still qualifies for the 50% discount. Any gain after that date falls under the new indexation rules. The ATO will require a market valuation or formulaic apportionment at the transition date. Investors who ignore this split risk overpaying or underpaying tax and triggering an audit.

Believing the trust changes only affect high-net-worth investors

From 1 July 2028, a 30% minimum tax applies to discretionary trust distributions. This affects any family trust that distributes rental income or capital gains from property. The trustee pays the tax, and beneficiaries cannot claim a refund if their personal rate is lower. Rollover relief is available for three years from 1 July 2027 to move assets into a company structure without immediate tax, but that window closes quickly. If you hold property through a discretionary trust, this is not a distant concern — it is a 2028 deadline that requires planning now.

What I see most often is people underestimating the cash-flow impact of ring-fenced losses. If you are buying an established property after Budget night and relying on the tax refund to cover the shortfall, that refund is gone. You need to fund the full holding cost yourself until the property generates enough income or you sell. If you need clarity on how this affects your situation, a service like JustAnswer Finance can connect you with a tax professional who can walk through your numbers.

How the New Property Tax Rules Actually Work

Negative gearing: what counts as a deduction, and where it goes

From 1 July 2027, if you own an established property bought after 12 May 2026, you can still deduct all the usual costs — interest, rates, repairs, management fees, depreciation. The difference is where those deductions apply. They no longer reduce your salary or business income. Instead, they offset only your rental income from that property or other residential properties, and any unused amount carries forward to reduce your capital gain when you sell. The ATO keeps a running tally of your ring-fenced losses. For new builds, the old rules stay: losses offset any income, including wages.

CGT: how indexation works and the 30% floor

Instead of halving your capital gain, you now adjust the original purchase price by CPI over the holding period. If inflation runs at 2.5% over seven years, that is roughly a 19% increase in the cost base. You then pay tax on the remaining gain at your marginal rate, but never below 30%. The government projects this will raise more revenue from high-growth properties while protecting low-income investors from paying less than 30% on their gains. Investors in new builds can choose between the old 50% discount and the new indexation method at sale — whichever gives the lower tax bill.

Trust distributions: the 30% minimum tax from 2028

If you hold property through a discretionary trust, the trustee pays a 30% minimum tax on distributions from 1 July 2028. Beneficiaries receive a credit for this tax but cannot claim a refund if their personal rate is below 30%. The government expects this to raise $4.47 billion in 2029-30 alone. Rollover relief allows you to transfer assets into a company structure without triggering CGT, but only during the three years from 1 July 2027. After that window closes, restructuring becomes more expensive.

First home buyers: what the data actually projects

Treasury modelling projects 75,000 additional owner-occupiers over the next decade, with house prices growing roughly 2% less than they would have without reform. The mechanism is straightforward: reduced investor demand for established properties means less competition at lower price points. However, investors are expected to pivot toward new builds, which will keep that segment competitive. The government’s $10 billion commitment to build up to 100,000 homes for first home buyers, with construction starting in 2026-27, adds supply-side support. But the modelling assumes these homes actually get built, which depends on council approvals, infrastructure funding, and construction capacity. The process of buying a house and lot in Australia now involves weighing these market dynamics alongside the tax changes.

Does the 60% CGT discount for new housing still exist?
Yes. A 60% CGT discount is retained for specific types of new housing. Investors in new builds can choose between the 50% discount, the 60% discount, or the new indexation method at sale.
What if I bought an established property before Budget night but settle after 1 July 2027?
You are grandfathered if the contract was exchanged before 7:30pm AEST on 12 May 2026. Settlement date does not affect your grandfathering status.
Can I carry forward ring-fenced losses indefinitely?
Yes. Unused losses from established properties bought after Budget night can be carried forward and applied against future rental income or the eventual capital gain when you sell. No time limit applies.
Does the principal place of residence exemption still apply?
Yes. The main residence exemption from CGT is unchanged. These reforms affect investment properties only, not your own home.
What counts as a “new build” for negative gearing purposes?
Off-the-plan apartments, residential construction on vacant land, duplexes via knock-down rebuilds, and properties occupied less than 12 months before first sale. Renovations, extensions, and granny flats do not qualify.
Are these changes law yet?
Not yet. All measures were announced in the 2026 Budget on 12 May 2026 but still require legislation. Changes are typically backdated to the announcement date once passed.

If you are unsure how the trust changes affect your structure, a specialist service like JustAnswer Business Law can help you understand the options before the rollover relief window closes.

What the Reform Means for the Next Decade of Property Investment

The 2026 Budget is not a minor tweak. It is a structural reset that shifts the tax system away from rewarding property speculation and toward favouring wage earners and new housing supply. The grandfathering provisions protect existing investors, but anyone buying an established property from now on faces a fundamentally different tax treatment. The government’s own modelling acknowledges that investor behaviour will change — UBS analysts expect a reallocation of funds toward the share market and income-focused equities. For first home buyers, the next decade may offer the best window of opportunity in a generation. But the reforms depend on supply actually materialising, and the legislative process is not yet complete. The smartest move right now is to understand your own position — whether you are buying, selling, or holding — and plan around the dates that matter.
