Australia’s CGT Discount Cut Could Impact Rental Prices: FoundIt Report

Australia’s Proposed Capital Gains Tax Reform Sparks Fears of Rising Rents

As Australia prepares to unveil its federal budget in May 2026, a contentious proposal to reduce the capital gains tax (CGT) discount has ignited warnings from housing analysts and economists. The plan, which would scale back the long-standing 50% CGT discount for property investors, is raising alarms about potential rent hikes, particularly in low-income neighborhoods already grappling with a severe rental crisis. Independent research and government documents confirm the reform is under active consideration, though its final shape remains uncertain.

At the heart of the debate is Australia’s current CGT policy, which allows investors to halve their taxable capital gains on assets held for more than 12 months. Introduced in 1999, the 50% discount was designed to encourage long-term investment, including in the residential property market. However, critics argue the policy has disproportionately benefited wealthy investors while doing little to address housing affordability. The Australian Treasury has not yet released official details of the proposed changes, but leaks to major media outlets suggest the discount could be reduced to 25% or phased out entirely for certain property types.

A report by independent property analytics firm FoundIt, obtained by World Today Journal, projects that reducing the CGT discount could trigger a “significant contraction” in the rental market. The firm’s modeling indicates that landlords, facing higher tax bills on property sales, may pass costs onto tenants through rent increases. The impact could be most acute in low-income areas, where rental demand already outstrips supply. FoundIt’s analysis warns that without concurrent measures to boost housing supply—such as increased social housing construction or incentives for new developments—the reform could exacerbate the country’s rental affordability crisis.

How the Capital Gains Tax Discount Works—and Why It’s Controversial

Under Australia’s current tax system, capital gains on assets held for more than a year are taxed at half the investor’s marginal income tax rate. For example, an investor in the highest tax bracket (45%) would pay an effective CGT rate of 22.5% on property sales, compared to 45% on ordinary income. This discount has made property investment an attractive option for individuals and institutional investors alike, contributing to Australia’s high rate of investor-owned housing.

Proponents of the reform argue that the CGT discount has distorted the housing market, inflating property prices and benefiting those who can afford to invest over first-time buyers. Data from the Australian Bureau of Statistics (ABS) shows that investor-owned properties accounted for 27% of all housing stock in 2025, up from 23% a decade earlier. Meanwhile, the national rental vacancy rate has fallen to a historic low of 1.1%, according to SQM Research, with rents rising by an average of 8.5% over the past year in major cities like Sydney and Melbourne.

Opponents, however, warn that reducing the CGT discount could backfire. The Property Council of Australia, a leading industry group, has argued that the policy change would discourage investment in rental properties, further tightening supply. In a submission to the Treasury, the council stated: “Any reduction in the CGT discount must be accompanied by measures to stimulate new housing construction, or we risk worsening the rental crisis.”

Who Stands to Be Affected?

The proposed reform would have far-reaching implications for multiple stakeholders:

• Property Investors: Landlords, particularly those with multiple properties, would face higher tax liabilities when selling assets. This could prompt some to exit the market, reducing the overall supply of rental housing. However, others may hold onto properties longer to avoid triggering capital gains, potentially limiting turnover in the market.
• Tenants: Low- and middle-income renters are most vulnerable to rent increases. FoundIt’s report highlights that areas with high concentrations of rental properties, such as western Sydney and Melbourne’s outer suburbs, could observe rents rise by as much as 10–15% if the reform is implemented without safeguards. Advocacy groups like Anglicare Australia have called for targeted rent subsidies to protect vulnerable households.
• First-Time Buyers: While the reform aims to level the playing field for owner-occupiers, its impact on housing affordability is uncertain. If investor activity declines, property prices could stabilize or even fall in some markets, but this may be offset by reduced supply if landlords sell up.
• Government Revenue: The Treasury estimates that reducing the CGT discount could generate an additional AUD $2–3 billion annually in tax revenue. However, this figure assumes no behavioral changes among investors. If landlords exit the market en masse, the government could see a decline in other revenue streams, such as land tax and stamp duty.

Global Comparisons: How Does Australia’s CGT Policy Stack Up?

Australia’s 50% CGT discount is one of the most generous among developed nations. For comparison:

Australia’s proposed reform would bring its CGT policy more in line with international norms, but the timing of the change is critical. Unlike countries with stable housing markets, Australia is currently experiencing a severe rental shortage, with vacancy rates below 1% in some cities. Economists warn that without complementary policies to boost housing supply, the reform could have unintended consequences.

What Happens Next?

The federal government is expected to release its budget on May 14, 2026, with the CGT reform likely to be a centerpiece. Key dates to watch include:

• May 14, 2026: Federal budget announcement, including details of the CGT reform and any accompanying measures to address housing supply.
• June–July 2026: Parliamentary debate and potential amendments to the legislation. The opposition has signaled it will push for safeguards to protect renters.
• January 1, 2027: Earliest possible implementation date, if the reform passes parliament. Some analysts suggest a phased approach to minimize market disruption.

In the meantime, housing advocates are urging the government to pair the CGT reform with concrete steps to increase affordable housing. “Tax reform alone won’t solve the rental crisis,” said Kate Colvin, spokesperson for the Everybody’s Home campaign. “We necessitate a national plan to build 500,000 social and affordable homes over the next decade, alongside measures to protect renters from price gouging.”

Key Takeaways

• Proposed Reform: The Australian government is considering reducing the 50% capital gains tax discount for property investors, a policy in place since 1999.
• Potential Impact: Analysts warn the change could lead to higher rents, particularly in low-income areas, unless accompanied by measures to boost housing supply.
• Stakeholders: Investors, tenants, first-time buyers, and the government all stand to be affected, with low-income renters at greatest risk of rent hikes.
• Global Context: Australia’s CGT discount is among the most generous in the world, and the proposed reform would align it more closely with international norms.
• Next Steps: The federal budget, due May 14, 2026, will reveal the details of the reform. Parliamentary debate and potential amendments will follow.

As Australia grapples with its housing crisis, the CGT reform debate underscores the complex trade-offs between tax policy and affordability. For now, tenants, investors, and policymakers alike are watching closely to see how the government balances fiscal responsibility with the urgent need for accessible housing.
