The Current System
Under the current rules, Australians who hold an asset — such as an investment property or shares — for more than 12 months are entitled to a 50% discount on any capital gain before it is added to their taxable income. This concession has been in place since 1999 and has been a cornerstone of long-term property investment strategy.
Example: On an $800,000 capital gain at a 47% marginal tax rate, the current 50% discount reduces the taxable amount to $400,000, producing a CGT bill of approximately $188,000. Without the discount, that bill rises to $376,000.

What Is Being Proposed?
Reporting from The Weekend Australian and other outlets indicates the government is weighing several options:
• Replace the flat 50% CGT discount with an inflation indexation model, meaning only 'real' gains above inflation would be taxed — similar to the pre-1999 Keating-era approach.
• Reduce the CGT discount from 50% to either 33% or 25% for newly acquired assets.
• Restrict negative gearing — either ring-fencing losses so they can only offset investment income (not wage income), or capping the benefit to a maximum of two investment properties per taxpayer.

Who Is Affected and How?
Owner-Occupiers
The family home remains fully exempt from CGT, and no change to that exemption has been proposed. Owner-occupiers are not directly affected by these reforms.

Existing Investors
Current indications strongly suggest that grandfathering provisions will protect existing holdings. Any changes are expected to apply only to assets acquired after the legislation takes effect — consistent with how every previous CGT reform in Australia has been implemented.

New Investors (Buying After Any Change)
This is where the reform bites hardest. A reduction from 50% to 33% on that same $800,000 gain would increase the taxable amount to $536,000 — resulting in a tax bill of approximately $251,920, or around $63,920 more than under current rules. The larger the gain and the higher the marginal rate, the greater the impact.

Investors with Negative Gearing
Investors currently using negative gearing to offset property losses against salary income could find that avenue restricted or eliminated for existing properties, with deductions potentially limited to new builds only.

Market and Investment Impacts
Broader market modelling suggests the effect on property prices would be modest. Grattan Institute and Treasury estimates point to a fall of approximately 2% in house prices, with rents expected to remain broadly stable. First-home buyers are likely to gain some ground against investors in competition for established dwellings.

However, investor sentiment is a concern. A Money.com.au survey found that 61% of property investors signalled they might pull back from the market if both CGT and negative gearing changes proceed, raising questions about rental supply and the delivery of the government's 1.2 million homes target under the National Housing Accord.

Analysts also note that if investors hold grandfathered assets rather than sell, a short-term supply cliff could actually create a temporary price floor in some markets.

What Should You Be Doing Now?
With the budget just weeks away, now is the time to review your position — not panic. Key actions to consider:
• If you are considering selling an investment property with significant unrealised gains, model the tax outcome under both the current rules and the proposed changes to understand your window.
• If you are planning to purchase a new investment property, factor in the possibility that the CGT discount on that future gain may be reduced.
• Review your ownership structure — whether personal, trust, or SMSF — with your accountant, as the optimal approach may shift depending on the final reform design.
• Do not make rushed decisions based on speculation. Selling purely to avoid a tax change that may not eventuate — or may be grandfathered anyway — carries real costs.
The Bottom Line
The political will for reform is stronger than at any point since 1999. Two-thirds of Australians reportedly support some form of change, and a Senate inquiry has given the Treasurer clear political backing. Budget night on 12 May will confirm what is actually happening.
