Negative Gearing Is Dead for Established Homes: The 14-Month Window That Just Opened

The biggest tax reform since 1999 just landed

On Tuesday 12 May 2026, Treasurer Jim Chalmers handed down a Budget that almost no investor was positioned for. The two cornerstones of Australian property investing — unlimited negative gearing against wage income and the 50% capital gains tax discount — were both terminated for assets acquired after 7.30pm AEST on Budget night.

Critically, both measures commence 1 July 2027. Everything you own today, and everything contracted in the next fourteen months, is grandfathered under the old rules for the life of the asset.

This article is for the investor who is asking the only question that matters right now: what do I do between now and 30 June 2027?

What changes, and what does not

The grandfathering is the policy lever. Anything you settle on before 1 July 2027 under a contract dated before 8.00pm 12 May 2026 keeps the old rules until you dispose of it. Anything contracted after Budget night and settled before 1 July 2027 sits in a transitional bucket that Treasury has flagged but not yet legislated — flag this as the most unsettled corner of the policy.

Why this is bigger than the 2016 Labor proposal

The Bill Shorten 2016 policy proposed cutting the CGT discount from 50% to 25% and quarantining negative gearing to new builds. That proposal would have left the discount intact, just smaller.

The 2026 reform is structurally different. The CGT discount is abolished entirely for individuals. In its place sits a hybrid regime:

1. The cost base is indexed for CPI (the pre-1999 Keating regime, restored).
2. The net real gain is then taxed at marginal rates.
3. A 30% minimum effective tax rate applies on top — designed to ensure top-bracket taxpayers cannot fully wash a gain away through indexation in low-inflation environments.

Old regime (until 30 Jun 2027):
  Gain          = Sale price − Cost base
  Discounted    = Gain × 50%
  Tax           = Discounted × marginal rate
  Top-bracket effective rate = 22.5% (45% × 50%)

New regime (from 1 Jul 2027):
  Real gain     = Sale price − (Cost base × CPI factor)
  Tax           = max(Real gain × marginal rate, Real gain × 30%)
  Top-bracket effective rate = 30% (floor) or 45% (if no indexation relief)

In a 2-3% inflation environment over a typical 10-year hold, the new regime taxes a top-bracket investor roughly 60-80% more on the same nominal gain compared with the old 50% discount. The 30% floor is the binding constraint for high earners; for middle-bracket taxpayers the indexation does most of the work.

The four moves smart investors are making between now and 30 June 2027

1. Lock in 50% CGT treatment on the next asset

Every additional investment property contracted before midnight 30 June 2027 is grandfathered. If your buying horizon was 2027-2029 anyway, pull it forward. The cost of bringing a purchase forward 12 months is roughly 6.59% × 12 months ≈ 6.6% of holding cost. The benefit — preserving the 50% CGT discount on a $700,000 asset that might double over 20 years — is six-figure money.

The risk: a transition-period scramble pushes prices up 3-6% in 2026-27, eating most of the advantage. Watch auction clearance rates in Sydney and Melbourne over winter — they will tell you whether the market has priced this in.

2. Re-weight your borrowing toward your own name

Properties held in discretionary trusts lose negative-gearing flexibility anyway (trust losses are trapped). Properties held in company structures never had the 50% discount.

The new regime restores indexation to individuals only. SMSF property continues with the 33⅓% discount unchanged. The hierarchy of "best tax structures for new purchases" has flipped:

This is not advice to liquidate trusts — restructuring triggers CGT events. But for new acquisitions in the 2027-2030 window, SMSF and BTR start looking structurally cleaner than the default individual ownership we have all defaulted to since 1999.

3. Bring forward depreciation-heavy purchases

If you were going to buy a near-new property anyway, the depreciation schedule (Division 40 plant and equipment + Division 43 building allowance) becomes the single most powerful tax shield in your kit. A new $700,000 unit typically delivers $12,000-$18,000 of depreciation in year one, and depreciation does not stop being deductible against wage income post-2027 if you contract before Budget night cut-off.

Even better: the new regime explicitly preserves wage-income offsetting for new builds. A new build contracted in 2028 still gets the legacy treatment. So the "lock it in before 2027" rule is the conservative path — but new-build acquisitions remain a viable structure indefinitely.

4. Consider deliberately deferring sales

The other half of the strategy is on the disposal side. For long-held assets bought in the early 2000s, the 50% discount is locked in for as long as you continue to hold the asset. There is no forced realisation, no "deemed sale" at 30 June 2027. If you sell in 2028, the indexation regime applies. If you sell in 2034, the indexation regime applies. If you sell in 2050, the indexation regime applies. There is no clock running on grandfathering.

This is the policy's quiet asymmetry: it taxes future purchases harder but it does not reach back into existing portfolios. The single most valuable asset most investors now own is the position itself — the right to sell under the old regime, ten or twenty years hence.

What this means for the cohort that owns property today

Roughly 2.26 million Australians held an investment property in 2022-23 (ATO). Of these, 1.12 million were negatively geared, and roughly one third hold two or more. Every one of those positions just had its after-tax economics bid up by the reform: the supply of new negatively-geared positions is closed, but existing positions are unchanged.

The market response in the next 14 months will be a mix of:

• Strategic buying by existing investors who already understand the structure and are racing to add one more grandfathered position
• Strategic selling by investors who were planning to exit in 2028-2030 anyway — once the regime changes, selling under the old 50% rules becomes more valuable
• New-build re-rating as developers price in their structural advantage (expect off-the-plan premiums to widen)
• First home buyer relief in pockets where investor activity thins after July 2027

The investors who win this transition will not be the ones who panic. They will be the ones who treat the 14 months between now and commencement as the most valuable property-tax planning window of their professional lifetimes.
