Australias CGT Discount Is Gone: What Property Investors Were Never Told and What to Do Before 2027

For 25 years, Australian property investors operated under a clear understanding: hold your investment property for more than 12 months, sell it, and the capital gain would be discounted by 50% before being added to your taxable income. A $400,000 gain became a $200,000 taxable event. At a 47% marginal rate, the tax bill was $94,000.

That understanding is no longer accurate. The 2026 federal budget changed the CGT discount on residential investment property from 50% to 33%. The same $400,000 gain is now a $268,000 taxable event. The tax bill at the same marginal rate is $125,960.

The difference is $31,960 on a single $400,000 gain. On a $600,000 gain — realistic for a property held 10 to 15 years in a major market — the difference is nearly $50,000. On a $1 million gain, it is over $80,000.

Most Australian property investors do not know this change happened. Those who do know it often do not know it applies to them specifically, or what they can still do about it. This article covers both.

The 50% CGT discount for individuals on assets held more than 12 months has existed since September 1999, when it replaced the indexation method. For over two decades it was treated as a settled feature of the Australian tax system — something investors could rely on when making decisions about buying and holding property.

The 2026 federal budget introduced a targeted reduction: the discount on residential investment property specifically has been reduced from 50% to 33% for individual investors. The change does not affect:

• The owner-occupied main residence exemption (unchanged)
• CGT treatment inside superannuation funds (unchanged — SMSF accumulation phase retains 10% effective rate)
• CGT on commercial property or other asset classes (unchanged at 50% discount)
• Properties purchased before the relevant cutoff date under grandfathering rules

What it does affect: every Australian who owns a residential investment property in their personal name and sells it after the cutoff date will pay more CGT than they would have under the previous rules, even if they bought the property years ago and planned their finances around the old discount rate.

The government did not send letters. There was no national advertising campaign. The change was announced in a budget, passed through Parliament, and became law. It is now the operating reality for every property investor in Australia.

To understand what the change actually costs, here is the before-and-after comparison on the same $500,000 capital gain at three income levels.

Income $120,000 per year (marginal rate 39% including Medicare levy on the top slice):
Old discount (50%): $250,000 assessable, effective CGT approximately $78,000
New discount (33%): $335,000 assessable, effective CGT approximately $97,000
Additional tax: approximately $19,000

Income $150,000 per year (marginal rate 47%):
Old discount (50%): $250,000 assessable, CGT $117,500
New discount (33%): $335,000 assessable, CGT $157,450
Additional tax: approximately $39,950

Income $200,000 per year (marginal rate 47%):
Old discount (50%): $250,000 assessable, CGT $117,500
New discount (33%): $335,000 assessable, CGT $157,450
Additional tax: approximately $39,950

The additional tax is purely a function of the marginal rate applied to the extra $85,000 of assessable income (the difference between 50% and 33% discount on a $500,000 gain). At 47%, that is $39,950 extra per property sale, per investor. Not a rounding error. Not an edge case. A meaningful structural shift in the after-tax return on every residential investment property held in personal name.

The insidious aspect of this change is not the change itself — governments adjust tax policy. It is the timing of decisions made years or decades before the change, when investors reasonably believed the rules would be stable.

An investor who bought a property in 2012 for $400,000, chose to hold it rather than selling in 2019 because they expected to realise the full 50% discount at exit, and now plans to sell in 2026 or 2027, had their financial planning upended by a rule change made years after the original investment decision.

This is not hypothetical. It describes hundreds of thousands of Australian property investors. They made holding decisions — against selling early, against crystallising gains in lower-income years, against selling before certain tax changes took effect — partly based on a CGT environment that has now materially changed without any notice to the individual affected.

The government has not retroactively changed the tax treatment of past gains. But by changing the discount on future sale events, it has effectively changed the expected after-tax return on an investment that was made, and held, under different rules. The distinction is legally correct and economically cold comfort.

The change is law. The discount is 33%. These facts cannot be changed. But the strategies available to reduce what you pay remain — and some are more valuable than ever precisely because the baseline tax has increased.

1. Sell in a low-income year. The marginal rate applied to the gain depends on your total assessable income in the year of sale (determined by the contract date). If you are within 5 years of retirement, a year in which your income drops significantly — parental leave, redundancy, a business transition — is worth planning a sale around. The difference between 47% and 32.5% applied to the assessable gain is significant even at the new 33% discount.

2. Apply the main residence exemption if it applies. If you lived in the property before renting it out, the 6-year main residence rule may exempt some or all of the gain. This is entirely unaffected by the CGT discount change and is worth understanding before any sale. For properties where the rule applies fully, the effective CGT rate is zero regardless of the discount change.

3. Offset capital losses. Losses from other investments realised in the same financial year reduce the net capital gain before the discount and marginal rate are applied. Coordinating the sale of underperforming assets with a property sale remains an effective and entirely legal approach.

4. Maximise the cost base. A higher cost base means a smaller gain, which means less tax at any discount rate. Every eligible capital expenditure — purchase costs, capital improvements, selling costs — reduces the gain. In a higher-tax environment, the value of thorough cost base documentation has increased.

5. Sell via SMSF in pension phase. If the property is inside a self-managed super fund and the fund is in pension phase, the CGT rate is zero. The discount change applies only to personal holdings. The SMSF pension phase exemption is unchanged. On a $500,000 gain, the difference between personal sale at the new effective rate and SMSF pension phase sale is $157,450. That is not a rounding error either.

Several factors converge in 2026-27 to make it the most significant tax year for property investors in a generation.

The CGT discount change is now in effect. Sales completing from the relevant cutoff date onward are subject to the 33% discount, not 50%.

Division 296 takes effect from 1 July 2026. Super balances above $3 million face an additional 15% tax on earnings. Investors considering whether to sell property personally or wait until they can sell via a pension-phase SMSF need to model both scenarios now — the relative advantage of the SMSF route has widened significantly.

Negative gearing changes for new purchases. Properties purchased after the relevant cutoffs cannot immediately offset losses against other income. For investors considering selling one property to fund the purchase of another, the tax environment of that future property is now materially different from what was expected.

The window that matters: between now and 30 June 2027, investors with properties approaching the sale decision point need to model the current environment, not the one they bought into. The strategies still available — income-year timing, loss crystallisation, cost base documentation, SMSF structuring — are worth more in a higher-tax environment than they were before.

Decisions made before the contract is signed are worth tens of thousands of dollars. Decisions made after are not available at any price. For the full 2026 CGT calculation guide: capital gains tax on investment property Australia: what you will actually pay in 2026.

The CGT discount reduction sits alongside the Division 296 tax on large super balances, the negative gearing changes for new purchases, and the tightening of various property-related concessions introduced over the previous decade. Each change, announced individually, framed individually, and passed individually, forms a coherent pattern: the tax treatment of wealth accumulated through property and superannuation in Australia is being systematically tightened.

This is not speculation about future policy. It is an accurate description of laws already in force. The investor who assumes 2025 rules apply to a 2027 sale decision is making an expensive mistake. The investor who understands the current environment and plans around it — legally, deliberately, and in advance — is doing exactly what the tax system allows.

Record numbers of Australians are setting up SMSFs. Record numbers are consulting property strategists and tax advisers before making sale and purchase decisions that would previously have been casual. The response to a changed environment is not panic — it is adaptation.

The investors who retire most comfortably from the 2026 cohort will be those who understood exactly what changed, exactly what it cost them, and exactly what they could still do about it.
