Australia’s negative gearing rules are changing from July 2027, but whether you’re protected depends entirely on one critical date: 7:30 PM AEST on 12 May 2026. Did you purchase your investment property before or after that exact moment?
Australia's rental property tax landscape has shifted significantly following the 2026 Federal Budget, announced on 12 May 2026. The changes to negative gearing, long a cornerstone of residential property investment strategy, are among the most consequential reforms in years. Whether these changes affect a current portfolio or future buying decisions depends almost entirely on when a property was or will be acquired, and what type of property it is. Getting the timing right is now as important as the investment itself.
The centrepiece of the 2026 Federal Budget property reforms is a structural limit on negative gearing for residential property, taking effect from 1 July 2027. Before this date, negative gearing has allowed property investors to offset net rental losses, where interest and other holding costs exceed rental income, directly against wages, business income, or any other assessable income. That broad offset is being wound back for established residential properties acquired after the Budget announcement deadline.
From 1 July 2027, net rental losses on affected established residential properties will be ring-fenced. Those losses can only be applied against income from other residential properties or capital gains from residential property disposals. They can no longer reduce a salary or business income directly in the year the loss arises. Excess losses are not permanently lost, because they carry forward. But the immediate tax benefit that has historically made negative gearing attractive to wage-earning investors is substantially reduced for new purchases of established homes.
The policy rationale, as stated in the Budget papers, centres on housing affordability: limiting the tax incentive for established property acquisitions is intended to ease competition from investors in the market for existing homes, while directing new investment toward housing supply through the new build exemption. Sources cited include Budget Paper No. 1, Budget Paper No. 2, and the Budget Speech.
The Federal Government has built a meaningful grandfathering provision into these reforms. Any residential property held before 7:30 PM AEST on 12 May 2026 — the moment of the Budget announcement — is fully exempt from the new restrictions for as long as that investor continues to own it. Full negative gearing against all income remains available on those properties until the time of sale.
An investor who purchased a negatively geared established property in, say, March 2026 continues to offset those rental losses against their salary income, indefinitely — right up until they sell. The grandfathering is tied to the ownership of that specific asset, not to the individual investor's overall circumstances. This protection preserves the investment case for anyone who acted before the deadline.
For established residential properties acquired under contracts exchanged after 7:30 PM AEST on 12 May 2026, the restricted ring-fencing rules apply from 1 July 2027. From that date, losses from those properties can only be offset against residential property income or capital gains — not against wages or business income. The date of contract exchange, not settlement, is what determines which rules apply, making accurate record-keeping around transaction dates essential.
Under the new framework, an investor holding an affected established residential property that runs at a net loss each year cannot use that loss to reduce their taxable salary or business income. The loss is instead quarantined, confined to a pool that can only be relieved by income from other residential rental properties or gains realised on the sale of residential property.
For many investors, this changes the economics substantially. Consider an investor earning $120,000 in wages with one established investment property generating a $15,000 net rental loss. Under previous rules, that loss reduces taxable income to $105,000. Under the new rules (for properties acquired after the deadline), that $15,000 sits in a ring-fenced pool with no immediate offset against wages. The tax saving that made the negative gearing strategy financially advantageous in the short term is, in effect, deferred rather than delivered annually.
Losses that cannot be used in the current year are not forfeited. They carry forward indefinitely and can be applied in future income years when the investor derives residential property income — either from rental receipts that exceed expenses on other properties, or from a capital gain on the disposal of a residential property. The deduction is not permanently lost, but the timing benefit, which is the core value of negative gearing, is removed for the period the loss sits unused.
Investors with multiple residential properties may find natural offset opportunities within their portfolio, particularly if some properties are positively geared. In that case, carried-forward losses from an established negatively geared property can be applied against the net income from the positively geared ones. Portfolio structure and the mix of new versus established properties will become significant tax planning considerations from 1 July 2027 onwards.
The single most significant planning consideration arising from the 2026 Budget changes is the treatment of new builds. Properties that qualify as new residential builds are explicitly exempt from the negative gearing restrictions. Investors who purchase newly constructed residential properties, regardless of when the contract is exchanged, retain the ability to offset net rental losses from those properties against any income, including wages and business income.
This is a deliberate policy exemption designed to channel investor demand toward new housing supply rather than existing stock, competing directly with owner-occupier buyers. For investors, it creates a tax incentive to consider new builds over established properties in post-deadline acquisition decisions. Financial modelling now needs to account not just for yield and capital growth prospects, but also for which negative gearing treatment applies, and what that means for after-tax cash flow over the holding period.
Commercial property investors can proceed without adjusting their tax planning for these specific reforms. The negative gearing changes apply exclusively to residential property. Commercial and other non-residential assets remain under existing tax arrangements, with net losses from those investments continuing to be deductible against all assessable income without restriction.
This distinction matters for investors with mixed portfolios spanning residential and commercial holdings. The commercial component of a portfolio is unaffected — losses from office, retail, or industrial holdings continue to flow through to general income offsets as before. Only the residential component of a portfolio acquired after the deadline is subject to the new ring-fencing treatment, and even then, only where the properties are established rather than new builds.
The 2026 Budget changes do not exist in isolation. Rental property deductions have been progressively tightened since 2017, and those earlier restrictions remain fully in force. Investors reviewing their position should confirm that the following existing limitations are already being correctly applied.
Following the Treasury Laws Amendment (Housing Tax Integrity) Bill 2017, travel expenditure incurred in earning income from residential premises has been non-deductible since 1 July 2017. This covers costs like driving to inspect a property, check on maintenance, or attend to tenancy matters. These expenses also cannot be added to the cost base of the property for Capital Gains Tax purposes.
The only exceptions are for taxpayers genuinely carrying on a business of letting rental properties, or for excluded entities such as certain corporate structures. For the vast majority of individual residential investors, this deduction has simply been unavailable for nearly a decade, despite still appearing on some tax returns incorrectly.
Also introduced through the 2017 housing tax integrity measures, depreciation deductions for plant and equipment in residential rental properties are restricted to assets that the investor themselves purchased new. An asset is considered 'previously used' if another entity used it before the current owner, or if it was used privately by the current owner in a prior period.
In practice, this means that when an established residential property is purchased, the purchaser cannot depreciate the value of existing fixtures, appliances, or fittings in the property, even if those items still have remaining effective life. Depreciation schedules based on valuations of existing depreciable assets in a second-hand property purchase no longer generate deductions in the way they once did. Certain entities are excluded from these restrictions, including corporate tax entities, superannuation funds (other than SMSFs), public unit trusts, and managed investment trusts, consistent with the exclusions that apply to related housing tax integrity measures.
From 1 July 2019, holding costs associated with vacant land — including interest on loans, land tax, council rates, and maintenance expenses — are generally not deductible for individuals, SMSFs, partnerships, and trusts. The restriction applies where the land is not being used to carry on a business.
This measure was specifically designed to prevent investors from claiming deductions on land held speculatively, where no income-producing activity is occurring. It affects those who purchase land with the intention to build but have not yet commenced construction or a qualifying business activity on the site. Costs that would otherwise have been deductible are quarantined until the land begins generating assessable income.
Alongside the negative gearing changes, the 2026 Federal Budget proposes a significant reform to the Capital Gains Tax discount that has applied to residential property disposals since September 1999. Currently, individual investors who hold a property for more than 12 months before sale are entitled to a 50% CGT discount on the net capital gain — effectively halving the taxable gain.
From 1 July 2027, the Budget proposes to replace the 50% discount with cost base indexation and a 30% minimum tax on capital gains. Cost base indexation adjusts the original purchase price for inflation between acquisition and disposal, reducing the nominal gain that is subject to tax. The 30% minimum tax floor then applies to the resulting indexed gain.
The interaction between the CGT changes and the negative gearing restrictions is worth noting. Carried-forward ring-fenced rental losses can be applied against residential property capital gains, so the CGT event on disposal may offer the first practical opportunity to utilise losses that have been building up over a holding period. Understanding how these two changes interact, particularly for properties acquired after 12 May 2026, is essential to accurate long-term investment modelling.
With 1 July 2027 as the operative date, there is still a planning window — but it is closing. Investors and advisers should be taking stock of their current property holdings, reviewing the acquisition dates against the 12 May 2026 deadline, and confirming whether each property qualifies as a new build, an established property under grandfathering, or an established property subject to the new restrictions.
Key questions worth working through now:
None of these questions require waiting until 1 July 2027 to answer. The proposed rules are known now, and the earlier a property's position is assessed, the more flexibility remains for portfolio adjustments, financing decisions, or acquisition timing. For investors considering new purchases, the distinction between new builds and established properties has shifted from a personal preference to a structurally significant tax decision.
