Labor's CGT Discount Reform: What the May 2026 Budget Could Mean for Property Investors
The CGT Discount Is Under Serious Threat
For the first time in over two decades, Australia’s 50% capital gains tax discount for property investors faces a genuine prospect of being reduced. And unlike previous election cycles where CGT reform was floated and then shelved, the political conditions in 2026 are different.
On 17 March 2026, a Greens-led Senate inquiry released its findings, recommending that the Howard-era CGT discount be reformed because it is “skewing the ownership of housing away from owner-occupiers and towards investors.” The report found the discount contributes to “income and wealth inequality and intergenerational inequality.”
Critically, Treasurer Jim Chalmers has signalled willingness to act. Treasury is reportedly modelling changes that could appear in the May 2026 federal budget, scheduled for 12 May. Labor holds a majority in the House of Representatives, and the Greens (who hold the balance of power in the Senate) are pushing for even more ambitious reform.
This isn’t idle speculation. This is policy machinery in motion.
How the CGT Discount Currently Works
Before diving into the proposed changes, let’s be clear about the current rules.
When you sell a capital asset (such as an investment property or shares) for more than you paid for it, the profit is a capital gain. In Australia, capital gains are added to your taxable income and taxed at your marginal tax rate.
However, if you’ve held the asset for more than 12 months, you receive a 50% discount. Only half the gain is included in your taxable income.
Current CGT Calculation Example
| Detail | Amount |
|---|---|
| Purchase price (2020) | $750,000 |
| Sale price (2026) | $1,050,000 |
| Capital gain | $300,000 |
| 50% CGT discount | -$150,000 |
| Taxable capital gain | $150,000 |
| Tax payable (37% bracket) | $55,500 |
The 50% discount was introduced in September 1999 by the Howard government, replacing the previous system where gains were indexed to inflation using CPI adjustments. The rationale was simplicity: rather than complex indexation calculations, a flat 50% discount would approximate the effect of inflation over typical holding periods.
The problem, critics argue, is that the discount significantly overcompensates for inflation during periods of high property price growth, effectively subsidising speculative investment in housing.
What’s Being Proposed
Based on the Senate inquiry findings and media reporting, Treasury is modelling a targeted reduction:
| Element | Current Rules | Proposed Change |
|---|---|---|
| CGT discount for residential investment property | 50% | 33% |
| CGT discount for shares and other assets | 50% | 50% (unchanged) |
| Discount for superannuation funds | 33.3% | 33.3% (unchanged) |
| Holding period requirement | 12 months | 12 months (unchanged) |
| Grandfathering | N/A | Likely for existing holdings |
The key design feature is that the reduction would target housing investments specifically, leaving the discount for shares, managed funds, and other assets untouched. This addresses the core criticism that the current discount fuels demand for investment property at the expense of first home buyers, without disrupting broader investment markets.
What a 33% Discount Would Mean in Practice
Using the same example as above:
| Detail | 50% Discount (Current) | 33% Discount (Proposed) |
|---|---|---|
| Capital gain | $300,000 | $300,000 |
| Discount applied | $150,000 | $99,000 |
| Taxable capital gain | $150,000 | $201,000 |
| Tax payable (37% bracket) | $55,500 | $74,370 |
| Additional tax | - | $18,870 |
For an investor in the top marginal tax bracket (45% plus 2% Medicare levy), the difference is even more pronounced:
| Detail | 50% Discount | 33% Discount |
|---|---|---|
| Capital gain | $300,000 | $300,000 |
| Taxable capital gain | $150,000 | $201,000 |
| Tax payable (47%) | $70,500 | $94,470 |
| Additional tax | - | $23,970 |
On a $500,000 capital gain (not uncommon for long-held Sydney or Melbourne properties), the additional tax for a top-bracket investor would be approximately $39,950.
The Political Landscape: Why This Time Is Different
Labor has been burned by CGT reform before. At the 2016 and 2019 elections, the party took policies to reduce the CGT discount and limit negative gearing, and lost both times. The 2019 defeat, in particular, was partly attributed to a voter backlash against perceived “attacks” on property investors.
So why is 2026 different?
1. Labor has a House majority and Greens support in the Senate
The parliamentary arithmetic works. Labor can pass legislation through the House on its own. In the Senate, the Greens are actively pushing for CGT reform, giving the government a clear path to passage.
2. The housing affordability crisis has worsened
Since 2019, national median dwelling values have risen from approximately $530,000 to $922,838 (Cotality, February 2026). Home ownership among 30-34 year olds has dropped from 57% to 50%. The political pressure to act on housing affordability has intensified.
3. The framing has shifted from “tax grab” to “fairness”
The Australian Council of Social Services (ACOSS) released data in March 2026 showing that the five highest-earning electorates capture 22% of all CGT discount expenditure, compared with just 1.6% for the bottom 10 electorates. This framing, that the discount disproportionately benefits wealthy investors, has shifted the political debate.
4. Grandfathering neutralises the biggest objection
The most potent argument against CGT reform in 2019 was that it would “change the rules” on people who had made investment decisions based on existing settings. Multiple expert witnesses at the Senate inquiry recommended grandfathering, meaning existing investments would retain the 50% discount. Only new purchases after the change would be subject to the reduced rate. This removes the retrospective element that made the 2019 policy so toxic.
5. The Coalition is focused on supply, not defending the discount
While Coalition senators rejected the inquiry’s recommendations, their counterargument focused on housing supply rather than mounting a full-throated defence of the CGT discount itself. Senator David Pocock’s compromise proposal (removing the discount for properties bought after 1 July 2026, with a 25% discount for new builds) suggests a centre-ground position is possible.
What Grandfathering Would Look Like
Based on the inquiry testimony and Treasury modelling leaks, the most likely design is:
- Properties purchased before the commencement date (likely 1 July 2026 or budget night, 12 May 2026) would continue to receive the 50% discount when eventually sold
- Properties purchased after the commencement date would receive the reduced 33% discount
- The holding period requirement (12 months) would remain unchanged
- The discount for non-housing assets (shares, managed funds, collectibles) would remain at 50%
This means if you already own investment properties, the change would not affect you when you sell them, regardless of when you sell. The reduced discount would only apply to your next property purchase.
What Should Investors Do Before the May Budget?
If you’re considering buying an investment property
The obvious question: should you buy before the budget to lock in the 50% discount?
It depends on your time horizon and investment thesis. If you were already planning to buy, bringing the purchase forward to before budget night (12 May) or before 1 July 2026 could preserve the 50% discount on that specific property. But buying a property solely to lock in a tax concession, without a sound underlying investment case, is rarely a good idea.
The additional tax under a 33% discount is meaningful but not enormous for moderate gains. On a $200,000 capital gain at the 37% tax bracket, the difference is about $12,580. That’s a factor in your decision, but it shouldn’t override fundamentals like location, yield, growth prospects, and your overall financial position.
If you already own investment properties
If grandfathering applies (and all indications suggest it will), your existing properties are unaffected. You don’t need to rush to sell. In fact, panic selling could trigger a CGT event you weren’t planning for, potentially at a suboptimal time.
If you were planning to sell soon
If you were already considering selling an investment property in the next 12 months, the CGT reform is unlikely to change your calculus (your existing property would be grandfathered). However, you should still time the sale carefully for your overall tax position. Selling before 30 June 2026 locks the gain into the current financial year, while selling after 1 July 2026 pushes it into FY2026-27. Your accountant can model which year produces the better after-tax outcome based on your other income.
If you invest through a company or trust
Companies don’t receive the CGT discount at all (they pay the company tax rate on the full gain). Trusts can distribute capital gains to beneficiaries who then apply their individual discount. If the discount is reduced for housing, this could affect the attractiveness of holding residential property in certain trust structures, though the impact depends on the specific design of the legislation.
SMSF trustees should note that the super fund CGT discount (33.3% in accumulation phase, with full exemption in pension phase) is not expected to change.
Impact on Property Prices
The big question: would a reduced CGT discount push property prices down?
The honest answer is that the impact would likely be modest and gradual, not dramatic.
Arguments for a price impact
- Reduced after-tax returns make property investment relatively less attractive compared to shares (which would retain the 50% discount)
- Marginal investors (those weighing property against other asset classes) may shift allocation away from housing
- Over time, reduced investor demand could slow price growth, particularly in investor-heavy markets
Arguments against a significant price impact
- Grandfathering means the change only affects new purchases, not the existing stock of investment properties
- Australia’s housing supply shortage remains the dominant driver of prices
- Owner-occupier demand (driven by population growth, migration, and household formation) is unaffected by CGT settings
- Interest rates, employment, and income growth have far larger effects on property prices than CGT policy
Treasury’s own modelling from previous reviews has consistently found that CGT discount changes would have a “modest and gradual” impact on dwelling prices, typically estimated at 1-2% over a multi-year period.
The more significant impact may be on investor behaviour rather than prices. Investors may hold properties longer (to reduce the annual CGT impact via lower marginal rates in retirement), invest in new builds (if a higher discount for new housing is introduced, as Pocock suggests), or shift toward shares and other assets that retain the full 50% discount.
The Negative Gearing Connection
It’s worth noting that the Senate inquiry also touched on negative gearing, though the immediate focus is on the CGT discount. The two policies are deeply connected: negative gearing allows investors to deduct property losses against their wage income during the holding period, while the CGT discount reduces the tax on the eventual sale.
Together, they create a strategy where investors accept rental losses (subsidised by the tax system) in exchange for lightly taxed capital gains on sale. Reforming one without the other creates an imbalanced outcome.
Treasury is reportedly considering the CGT discount change as a first step, with negative gearing reforms potentially following in a future budget. This staged approach would test the political waters with the less controversial change before tackling the more contentious issue.
For investors, this means the May 2026 budget may be just the beginning of a multi-year reform program. Understanding the direction of travel is important for long-term planning.
Tax Planning Strategies to Consider Now
Regardless of what happens in the May budget, there are several tax-planning moves worth considering before 30 June 2026:
1. Review your asset register
Know exactly what you own, when you bought it, and what your cost base is (including stamp duty, legal fees, and capital improvements). If CGT rules change, having clean records from day one will save you thousands in accounting fees later.
2. Harvest capital losses
If you hold any investments currently sitting at a loss (shares, managed funds, crypto), selling them before 30 June allows you to offset those losses against any capital gains you realise in the same financial year. Capital losses can also be carried forward indefinitely.
3. Maximise your cost base
Ensure all capital improvements, stamp duty, legal fees, and other acquisition costs are properly recorded and added to your cost base. A higher cost base means a lower capital gain when you eventually sell.
4. Consider your holding structure
If you’re planning to purchase property after any reform takes effect, the structure you use (individual, trust, company, SMSF) will interact differently with the new rules. Get advice before you buy, not after.
5. Contribute to superannuation
If you’re expecting a large capital gain in FY2025-26, maximising your concessional super contributions (currently $30,000 per year) reduces your taxable income and could push your capital gain into a lower tax bracket. If you have unused concessional cap amounts from previous years, the carry-forward rule allows you to contribute more.
6. Talk to your accountant now, not in June
The end of financial year rush means accountants are overwhelmed in May and June. Booking a strategy session now gives you time to implement any changes before 30 June.
What We Don’t Know Yet
There are several critical details that won’t be clear until the budget is delivered:
- The exact discount rate: 33% is the figure being modelled, but it could be different
- The commencement date: Could be budget night (12 May), 1 July 2026, or 1 July 2027
- The scope: Will it apply to all residential investment property, or could there be carve-outs for new builds?
- The grandfathering design: Will it be based on purchase date, contract date, or settlement date?
- Interaction with negative gearing: Will negative gearing changes be bundled in?
- Whether the legislation passes: The Senate crossbench is supportive, but the detail matters
The Bottom Line
The 50% CGT discount for residential property investors is likely to be reduced. The question is no longer “if” but “when and how.” The most likely scenario is an announcement in the 12 May 2026 budget, with a reduced 33% discount applying to properties purchased after the commencement date, and existing holdings grandfathered.
For most existing property investors, the practical impact will be minimal in the short term. Your current properties will almost certainly retain the 50% discount. But for anyone planning to buy their next investment property, the window to lock in the current settings may be closing.
Don’t make rushed decisions based on headlines. Get specific advice based on your situation.

Frequently Asked Questions
What is the current capital gains tax discount in Australia?
Australian individuals who hold an asset for more than 12 months before selling receive a 50% discount on their capital gain. This means only half the gain is added to their taxable income. For example, a $200,000 capital gain on a property held for two years would result in only $100,000 being added to your taxable income. The discount was introduced in 1999 under the Howard government, replacing the previous indexation method.
What changes to the CGT discount is the Australian government considering?
Treasury is reportedly modelling a reduction of the CGT discount from 50% to 33% for residential investment properties, while retaining the 50% discount for shares and other non-housing investments. A Greens-led Senate inquiry released in March 2026 recommended changes, and Treasurer Jim Chalmers has signalled willingness to act in the May 2026 budget. No final decision has been announced.
Would CGT discount changes in Australia be grandfathered?
Based on expert testimony to the Senate inquiry, grandfathering is considered highly likely. This would mean properties purchased before the change takes effect would continue to receive the current 50% discount when sold. Only properties bought after the new rules commence would be subject to the reduced 33% discount. This approach was recommended by multiple witnesses to avoid 'changing the rules' on existing investors.
How much more tax would Australian property investors pay under a 33% CGT discount?
It depends on your marginal tax rate and the size of your capital gain. For an investor in the 37% tax bracket with a $300,000 capital gain: under the current 50% discount, they'd pay $55,500 in CGT. Under a 33% discount, they'd pay $74,370 in CGT, an increase of $18,870. For investors in the 45% bracket, the difference would be even larger.
When could CGT discount changes take effect in Australia?
If announced in the May 2026 budget (12 May), changes could potentially take effect from 1 July 2026 or 1 July 2027, depending on the government's approach. Senator David Pocock has suggested a 1 July 2026 start date for new purchases. However, legislation would need to pass both houses of Parliament, which could delay implementation.
Should Australian property investors sell before the CGT discount changes?
Not necessarily. If changes are grandfathered (applying only to properties purchased after the new rules), existing investors would retain the 50% discount on current holdings. Panic selling based on speculation could trigger unnecessary CGT events and transaction costs. The most prudent approach is to consult an accountant or tax adviser who can model your specific situation before making any decisions.
