## What’s Changing and Who It Affects
From **1 July 2027**, significant reforms announced in the 2026-27 Federal Budget will reshape capital gains tax (CGT) and negative gearing for residential property. Key changes include:
- The **50% CGT discount** will be replaced with **inflation-adjusted indexation** plus a **minimum 30% tax on real gains**.([pm.gov.au](https://www.pm.gov.au/media/tax-reform-workers-businesses-and-future-generations?utm_source=openai))
- **Negative gearing** for established properties will be limited to rental property income only—meaning losses won’t be offset against other income for established dwellings. For **new builds**, both CGT discount (or the new option) and full negative gearing will still apply.([pm.gov.au](https://www.pm.gov.au/media/tax-reform-workers-businesses-and-future-generations?utm_source=openai))
- These reforms are **prospective**, meaning gains accrued before 1 July 2027 retain existing rules. Existing investments (before 7:30pm AEST 12 May 2026) are grandfathered for some concessions.([pm.gov.au](https://www.pm.gov.au/media/tax-reform-workers-businesses-and-future-generations?utm_source=openai))
## Strategies for Existing Investors
If you already own investment property, there's room to organise your affairs ahead of the changes:
- **Lock in existing treatment:** refrain from selling or restructuring properties before 1 July 2027 unless absolutely needed; gains before that date still receive the old CGT discount.
- **Evaluate your pressure on deductions:** since negative gearing for established properties will be curtailed, assess whether holding or disposing might be better depending on projected rental yields and property values.
- **New builds as a safe harbour:** investing in new builds gives flexibility—owners can choose between the old 50% discount or new indexation/minimum tax — plus use negative gearing.([pm.gov.au](https://www.pm.gov.au/media/tax-reform-workers-businesses-and-future-generations?utm_source=openai))
## What New Investors Should Know vs. Avoid
| **What to embrace** | **What to avoid or rethink** |
|----------------------|-------------------------------|
| New build investments if you want choice and full negative gearing. | Buying established property mainly for tax losses; losses may soon be restricted. |
| Structuring long-term investment plans with inflation in mind, since real gains are taxed. | Acquiring high-cost property expecting large nominal gains—tax reform may increase your bill. |
## Example Scenario
Let’s compare two property investors—you bought a house in 2012 for **AUD 500,000**, and its value is **$700,000** on 1 July 2027. You sell it in **2029** for **$1,000,000**. Under old rules, whole gain (sale minus cost) gets the 50% discount. Under new rules:
1. **Pre-1 July 2027 gain ($500k→$700k)**: qualifies for 50% CGT discount.
2. **Post-1 July 2027 gain ($700k→$1,000,000)**: taxed on *real gain* after inflation, with minimum 30% tax rate applying.
This split treatment makes your **holding date and the timing** crucial. On steep inflation, the post-July 2027 gain taxed under the new reforms may be substantially lower than it looks in nominal terms.
## What Investors Should Do Now
- Review portfolios to identify which investments are established vs new builds.
- Calculate estimated gains both under current and upcoming rules to see marginal tax impact.
- Consider selling some holdings before 1 July 2027 if you’ll lose the advantage under the new regime.
- Seek advice from tax professionals, especially if you hold discretionary trusts or corporate investment vehicles, as trust reforms are also on the horizon.
**Bottom line:** The upcoming CGT and negative gearing reforms mark one of Australia's biggest tax shifts in decades. If you're in the property investment game, early awareness and strategic planning between now and mid-2027 can save tens to hundreds of thousands of AUD—and ensure you’re optimised for the new rules.
