Treasurer Jim Chalmers handed down the 2026–27 Federal Budget on 12 May 2026, and the property sector is waking up to one of the most significant policy shifts in decades. Negative gearing and capital gains tax — two pillars of residential property investment — have been substantially reformed. Here's what it means for you.
FOR LANDLORDS
If you already own investment property, take a breath
The most important thing to understand is grandfathering. Properties owned before 7:30pm AEST on 12 May 2026 — Budget night — are protected. Existing investors can continue to claim negative gearing concessions on those holdings under the existing rules, until they choose to sell.
For most existing landlords, the day-to-day management of their current investment portfolio changes very little in the near term. The tax treatment you rely on is preserved for properties you already hold.
Where it gets complicated
If you're considering expanding your portfolio by acquiring an existing (established) dwelling after Budget night, the rules are different. Rental losses from those new purchases can no longer be immediately deducted against your wages or other non-property income. Instead, those losses are quarantined — they can only be used to offset future residential property income or capital gains from residential property.
The removal of negative gearing for established purchases is roughly equivalent to a 90–155 basis point increase in after-tax mortgage costs, depending on leverage and marginal tax rate. The benefit isn't gone entirely — it's deferred. But deferred tax savings are worth less in present value terms.
The strong incentive this creates is to hold existing properties rather than sell, since selling means losing the grandfathered treatment. This could reduce listings and support prices in the short term — which is worth watching if you're managing tenancy and rental pricing decisions.
FOR LARGE-SCALE INVESTORS
A new investment landscape — with a clear signal
For institutional and large-scale investors, the Budget represents a deliberate policy fork: the government is penalising investment in existing stock and actively incentivising investment in new supply — particularly built-to-rent.
The CGT changes are significant here. The existing 50% capital gains discount is being replaced with cost-base indexation and a 30% minimum tax rate from July 2027. Investors will still be protected from paying tax on the inflation component of a gain, but real capital gains above inflation will be taxed at marginal rates (subject to the 30% floor). For high-income investors with substantial holdings, this meaningfully changes the long-run return profile of established residential property.
Where capital is being redirected
The government's clear signal is that it wants institutional capital building new housing supply, not competing for existing stock. New residential builds retain full negative gearing treatment, relevant for individual investors buying off-the-plan apartments or new houses. For institutional vehicles such as managed investment trusts (MITs) and superannuation funds, the negative gearing rules work differently in any case: widely held trusts and super funds are explicitly excluded from the quarantining rules that apply to most investors.
The Budget also notes that elevated construction costs — partly linked to PVC-related pressures from the Middle East conflict — could dampen the attractiveness of new builds regardless of the tax settings. Investors will need to weigh the policy tailwind against real-world feasibility.
FOR FIRST HOME BUYERS
Less competition — but the market won't transform overnight
Treasurer Chalmers framed these reforms explicitly around affordability, noting house prices have risen more than 400% since 1999 — twice as fast as incomes. Treasury forecasts the changes will slow house price growth by around 2%, with the median-priced home expected to cost roughly $19,000 less than it otherwise would over the coming years.
The clearest benefit for first home buyers is reduced investor competition for established properties. When negative gearing no longer applies to new purchases of existing dwellings, the pool of active investors bidding against owner-occupiers shrinks.
The nuance worth understanding
The benefit may be partially diluted by two dynamics. First, existing investors with grandfathered properties have a stronger incentive to hold rather than sell — reducing listing supply even as buyer demand from investors softens. Second, some investors will pivot toward new builds, where negative gearing remains available, which could push demand into that segment instead.
Borrowing capacity and interest rates remain as important as ever for first home buyers. The budget's impact on inflation, and by extension the RBA's rate path, is an open question that market commentators are still debating.
The direction of change is positive for first home buyers — but the gains are incremental, not transformative. Structural supply constraints and elevated construction costs mean the underlying affordability challenge remains real.
BUILD TO RENT
What the Budget means for built-to-rent
It's worth being precise here, because BTR is often discussed alongside negative gearing in ways that can mislead. Institutional BTR operators — typically structured as managed investment trusts (MITs) owning an entire building — don't access negative gearing in the same way individual landlords do. The federal incentives for the BTR sector sit in a separate, purpose-built concession regime.
Under that regime, a MIT owning an active BTR development can access a concessional withholding tax rate of 15% (reduced from the standard 30%) on eligible fund payments, including rental income and capital gains from the development. Developments where construction commenced after May 2023 can also access an accelerated 4% depreciation deduction. These concessions were legislated previously and were not unwound by this Budget.
Separately, BTR developments receive a targeted exemption from the new negative gearing quarantining rules — meaning the Budget changes that affect individual investors acquiring established properties don't apply to BTR structures. This isn't a new benefit; it's a carve-out that preserves the status quo for the sector.
What has changed for BTR
The affordability requirements attached to the federal BTR concessions were tightened earlier in 2026. Under the amended rules, at least 2% of dwellings in a BTR development must be lower-income dwellings, with tenants identified through an eligible community housing provider. Existing BTR projects operating under the earlier legislative instrument are subject to different rules — operators should confirm with advisers which instrument applies to their development.
At state level, NSW has gone further in its own 2026 budget, extending its land tax concession for BTR to apply indefinitely — a meaningful signal of long-term policy support compared to the time-limited concessions in other states.
The broader takeaway for the BTR sector is that while this Budget didn't introduce new federal incentives, it has materially shifted the competitive landscape. The changes to negative gearing and CGT make traditional established-property investment considerably less attractive, which by comparison makes professionally structured, long-hold BTR more differentiated as an asset class.
For renters, the longer-term story is supply. If the BTR pipeline grows in response to a reoriented investment landscape, professionally managed, longer-tenure rental accommodation becomes more accessible. The Budget alone won't solve rental affordability, but the policy direction is pointing capital toward new supply rather than existing stock.
What should you do now?
The changes are significant but not yet law. Most measures require legislation before taking effect, and the 1 July 2027 start date provides a meaningful runway. That said, investment decisions being made today will be shaped by these rules.
Our advice: don't make rushed decisions based on headlines alone. The impacts vary considerably depending on your tax position, existing portfolio, leverage, and investment goals.
Speak to your accountant or financial adviser before making any material portfolio decisions, and talk to us about what these changes mean for managing your investment effectively in the months ahead.
