Important: The 2026 Federal Budget measures discussed in this article are proposed, not yet legislated. Seek tailored advice before making any decisions about your investment structure.
The removal of the 50% CGT discount is generating more anxiety than almost any other measure in the 2026 Federal Budget. That anxiety is understandable. For most property investors, it is also disproportionate to the real financial impact. The CGT discount only produces an outcome at the moment an asset is sold. Most Australian property investors do not sell. They hold, refinance, and accumulate. Treasury’s own modelling confirms the gap between the headlines and the numbers.
What the CGT Discount Change Does, and What It Does Not
From 1 July 2027, the 50% CGT discount for individuals, trusts, and partnerships is replaced by two mechanisms. The first is cost base indexation, the purchase price is adjusted for inflation using CPI, so only the real gain above inflation is taxed. The second is a 30% minimum tax floor on real capital gains. These are separate instruments. Indexation adjusts the calculation. The minimum tax prevents investors from deferring sales to low-income years to reduce the rate.
The change applies to gains accruing after 1 July 2027 only. For assets held at that date, the gain is split. Gains before 1 July 2027 retain the 50% discount. Gains after that date fall under the new rules. The asset’s value on 1 July 2027, determined by formal valuation or the ATO’s apportionment formula, becomes the dividing line.
The most widespread misconception in current coverage is that existing properties lose the discount immediately. They do not. The CGT discount on pre-2027 gains is preserved regardless of when the eventual sale occurs.
Why Investment Strategy Determines Everything
The CGT discount benefits investors who sell. If a strategy does not include selling, the discount produces zero value at any rate.
The typical Australian property investor operates on a cycle: buy, hold, refinance against equity, use that equity to fund the next purchase. Capital growth is extracted through refinancing, not through sale. In that model, a CGT event never occurs until retirement, estate planning, or a business exit forces a disposal.
For that investor, the headline debate about the 50% discount is a distraction. The rate applied to a gain that never gets realised costs nothing. The central question is not what the discount rate is. The central question is when, and if, you plan to sell.
What Treasury's Own Numbers Reveal
The official Treasury factsheet includes worked examples that have not been widely used in written commentary from accounting firms. The numbers tell a more nuanced story than the headlines.
Yoonseo’s scenario. An investor earning $100,000 buys an established residential property for $519,000 after budget night. She rents it out and sells it ten years later for $814,447. After applying carry-forward losses across the investment period, Yoonseo pays $186 more in nominal tax over ten years under the proposed rules compared to the old settings.
The growth rate is the deciding variable. Treasury modelled the same $500,000 property purchase in July 2027, held for ten years, at different returns:
- At 5% annual return (long-run residential average): pays $8,075 more tax
- At 2.5% annual return (matching inflation): pays $24,858 less tax, indexation works in the investor’s favour
- At 7.5% annual return (high-growth asset): pays $58,851 more tax
For the average residential property at average growth rates, the annual difference is approximately $800 per year. That is less than two weeks of average mortgage repayments.
When the Change Genuinely Matters
The article would be incomplete without acknowledging the scenarios where the CGT change produces a significant financial impact.
For high-growth assets growing at 7%+ annually, private business interests, long-held commercial assets, or exceptional residential performers, the change is real. Treasury’s own Jane scenario: she buys for $800,000 in 2022 and sells for $1,600,000 in 2032 at 7.2% annual growth. Her tax bill under the new rules is $228,252 compared to $188,000 under the 50% discount. A $40,252 difference is material.
The minimum tax also matters for investors who plan to time disposals to low-income years, retirement, sabbaticals, and years with offsetting business losses. That strategy is eliminated by the 30% floor.
Pre-1985 assets face entirely new exposure. Gains on assets held since before 19 September 1985 were previously fully exempt. From 1 July 2027, post-transition gains become taxable. Valuation at 1 July 2027 is now critical for those assets.
For investors in any of these categories, the period before July 2027 is a planning window that should not be missed.
The Annual Costs That Matter More
Investors focused on the CGT discount change often spend less time on the tax costs that compound against a portfolio every year, before any sale occurs.
A business owner drawing profits to fund a property deposit faces income tax at 47% on every dollar drawn. Funding a $200,000 deposit requires drawing approximately $377,000 before tax. The annual cost of accessing capital through a poorly structured vehicle exceeds the CGT discount differential on most residential sales.
In New South Wales, a discretionary trust holding a $2 million residential portfolio pays land tax on the full unthresholded value. The annual excess over a comparable company structure can exceed $16,000. Over ten years, that gap exceeds $160,000, without a CGT event ever occurring.
The structure holding investment property determines portfolio outcomes. So does the rate at which business profits fund it. Both matter far more than any discount rate applied at a sale most investors never make.
The Number That Matters More Than the Discount Rate
The CGT discount change matters to a specific profile: high-growth assets, long holding periods, and a disposal planned around a low-income year. For that investor, the period before July 2027 is a planning window.
For most residential property investors building equity through refinancing, Treasury’s own modelling shows the impact ranges from $186 to $8,000 over a decade. The structure holding the property matters more. The annual tax drag that compounds before any CGT event occurs matters more. Both will determine portfolio outcomes far beyond what any discount rate at sale ever could.

Frequently Asked Questions
Should I sell my investment property before 1 July 2027?
For properties held before 12 May 2026, transitional rules preserve the 50% discount on all pre-2027 gains. A decision to sell should be driven by investment strategy and overall financial position, not the discount change alone. At average residential growth rates, Treasury’s modelling shows the impact is modest.
Does the change apply to shares and business assets, not just property?
Yes. The reform applies to all CGT assets held by individuals, trusts, and partnerships for at least 12 months, including shares, managed funds, and private business interests. Companies are unaffected, they were never entitled to the 50% discount.
What is the 30% minimum tax?
The minimum tax applies where the effective rate on a capital gain would fall below 30%. For investors on a 30%+ marginal rate, it produces no additional cost. It targets the strategy of deferring sales to retirement or low-income years.
Do new builds retain the CGT discount?
Yes. Investors in eligible new residential builds can choose between the 50% discount and the new indexation rules at the time of sale. New builds also retain full negative gearing eligibility.
