## Introduction
The Australian Federal Budget delivered on **12 May 2026** introduced some of the most significant reforms to **Capital Gains Tax (CGT)** and **negative gearing** since their inception. For property investors, trusts, and anyone holding assets, these changes will influence both current and future tax planning strategies. This article breaks down what’s new and how to adapt.
## What’s Changing
### 1. Replacing the 50% CGT discount with cost base indexation + 30% minimum tax
- From **1 July 2027**, individuals, trusts, and super funds will **no longer access the standard 50% CGT discount**. Instead, gains will be taxed using **cost base indexation** (adjusting for inflation), paired with a **minimum tax rate of 30% on realised gains**.

- **Grandfathering exceptions**: Assets acquired before Budget night (12 May 2026, 7:30 pm AEST) will retain the 50% discount, even when disposed of after 1 July 2027. ([pm.gov.au](https://www.pm.gov.au/media/tax-reform-workers-businesses-and-future-generations?utm_source=openai))
### 2. Negative gearing restricted to new builds
- From **1 July 2027**, negative gearing deductions (net rental loss deductions) will only apply to **newly constructed residential properties**. Existing investments will be *grandfathered*, i.e. arrangements before 7:30 pm AEST on **12 May 2026** remain unaffected.

### 3. 30% minimum tax on discretionary trusts
- Starting **2028-29 income year**, incomes distributed from **discretionary trusts** will face a **minimum tax rate of 30%**, aligning them more closely with trust and personal income rates. ([austax.tools](https://austax.tools/budget-2026-27/?utm_source=openai))
## Why These Reforms Now?
These changes are part of the government’s wider plan to:
- Improve housing affordability and curb speculative investments. ([pm.gov.au](https://www.pm.gov.au/media/tax-reform-workers-businesses-and-future-generations?utm_source=openai))
- Restore fairness between wage earners and income from assets held in trusts. ([pm.gov.au](https://www.pm.gov.au/media/tax-reform-workers-businesses-and-future-generations?utm_source=openai))
- Preserve real gains by accounting for inflation through cost base indexation. ([ashurst.com](https://www.ashurst.com/en/insights/australia-federal-budget-2026-2027-key-tax-measures/?utm_source=openai))
## Practical Implications and Examples
- **Investor A**, who bought a rental property in 2021: under new rules, their future rental losses won't offset non-property income unless the property is a new build—but they still benefit from grandfathering.
- **Investor B**, bidding on a new build in 2027: eligible for negative gearing deductions and must understand that their capital gain will be taxed using indexation + minimum 30%, *not* the traditional 50% discount.
- **Trusts** distributing income face greater tax burdens—especially family trusts that rely heavily on discretion to distribute income to beneficiaries with low rates.
## What You Should Do Now
1. **Review your investment property portfolio**
- Identify which assets are grandfathered.
- Consider whether buying new builds may make sense under revised rules.
2. **Lock in gains before 1 July 2027 if possible**
- For assets held long enough, selling before reforms take effect could allow using the 50% CGT discount.
3. **Adjust trust structures**
- Reconsider distributions strategies under discretionary trusts to minimize impact of 30% minimum tax.
4. **Maintain excellent record keeping**
- Inflation indexation calculations and determining acquisition dates will be crucial.
5. **Plan with Inflation in mind**
- With cost base indexation replacing discount, understanding CPI indices before and after Sept 1999 will matter.
## Conclusion
These reforms represent major changes for anyone with investment assets, trusts, or property. If you own existing investments, make plans to ride out grandfathering windows. If you're considering new property purchases, especially new builds, these may offer opportunity. Working with a qualified tax adviser can ensure you implement strategies aligned with your financial goals under the new laws.
