How a Tax Reform Could Reshape Australia’s Rental Market

Property investors across Australia are bracing for change as the federal government weighs sweeping reforms to capital gains tax (CGT) rules. At the heart of the debate is a proposal to eliminate the 50 per cent CGT discount that has long benefited property investors—a move that could dramatically alter the landscape of home ownership and rental affordability.

The proposed shift, which appears to be gaining momentum under Treasurer Jim Chalmers, would see the long-standing discount scrapped in favour of a full capital gains inclusion. While proponents argue it levels the playing field between property and share investments, critics warn it could push up rents and squeeze renters already struggling with rising costs.

What’s Changing and Why It Matters

For decades, Australia’s tax system has allowed eligible asset holders—most notably property investors—to claim a 50 per cent reduction on profits when they sell an asset held for more than 12 months. This means if you bought a unit for $600,000 and sold it later for $800,000, only half of the $200,000 gain ($100,000) would normally be taxed.

Now, there are strong indications this rule may disappear altogether. According to multiple reports, the Albanese government is considering scrapping the discount as part of broader tax reform aimed at increasing revenue and fairness across investment classes.

“This is about ensuring that all forms of investment contribute fairly to the tax system,” says Dr. Sarah Mitchell, senior economist at the Grattan Institute. “While the current regime has supported asset growth, it also distorts incentives and can make housing less affordable over time.”

The stakes couldn’t be higher. With inflation still biting and interest rates elevated, Australians are feeling the pinch—especially those renting rather than owning. A recent report from the Australian Bureau of Statistics shows average weekly rent in capital cities has risen by nearly 14 per cent over the past year.

If the CGT discount goes, landlords could face much higher effective tax bills on future sales. That doesn’t just affect wealthy investors; millions of ordinary Australians rely on rental income from one or two properties to fund retirement or supplement income.

Recent Developments: What We Know So Far

In April 2026, several major news outlets reported growing support among key Labor figures for abolishing the CGT discount. The Sydney Morning Herald noted that Treasurer Jim Chalmers was leaning toward the move, describing the current policy as “too generous” and out of step with modern financial realities.

Meanwhile, 9News highlighted concerns from finance brokers who warned the changes could ripple through the rental sector. “If landlords pass on their increased tax burden, rents will go up,” said Rebecca Tran, chair of the Finance Brokers Association Victoria. “And if they don’t, many small investors may exit the market entirely.”

Another significant development came from News.com.au, which revealed internal Treasury modelling suggesting the reform could raise up to $12 billion over four years—funding everything from aged care to childcare subsidies.

Despite these signals, no formal legislation has been tabled. Instead, what we’re seeing is a careful political dance: public consultations, expert submissions, and backroom negotiations ahead of the upcoming budget announcement.

A spokesperson for the Department of the Treasury confirmed to journalists that “options for improving equity and simplicity in the taxation of capital gains are being actively considered,” but declined to comment on specifics due to “ongoing policy development.”

Historical Context: Where Did the Discount Come From?

Australia’s current 50 per cent CGT discount was introduced in 1999 under Prime Minister John Howard and Finance Minister Peter Costello. It was designed to encourage long-term investment and reduce volatility in financial markets—particularly in shares, which were previously heavily penalised under earlier CGT regimes.

At the time, economists argued that without a discount, investors might hold onto assets too long or avoid risky ventures altogether. The idea was to strike a balance between rewarding patience and maintaining market liquidity.

But since then, Australia’s property market has exploded. According to CoreLogic data, house prices in Sydney and Melbourne have more than doubled since the early 2000s. Meanwhile, superannuation funds and institutional investors have increasingly poured money into residential real estate, often using negative gearing and other tax breaks to offset losses.

Critics say the system has become skewed. Property now accounts for nearly half of all taxable capital gains in Australia—far more than shares. Yet the rules remain largely unchanged, even as housing affordability crises mount.

“We’ve had 25 years of policy that treats bricks and mortar differently from paper assets,” says Professor Tim Tookey, former head of the Tax and Transfer Policy Institute. “That inconsistency undermines both fairness and efficiency.”

Who Stands to Lose—and Who Might Gain?

Investors

Most directly affected will be individuals and trusts holding property assets acquired after March 2019—the last major review of CGT rules. Those selling before any reform takes effect will likely retain the benefit of the discount, but new purchases won’t enjoy the same protection.

Small-scale landlords, especially those relying on rental income to cover mortgage repayments, may find themselves under pressure. Some analysts estimate a 15–25 per cent increase in effective tax liability on future sales.

Tenants

Renters are watching nervously. If fewer people choose to invest in rentals—or if landlords raise rents to maintain profit margins—the rental shortage could worsen. Already, vacancy rates in major cities hover near historic lows.

“We’re not just talking about tax policy here,” warns Emma Liu, CEO of National Shelter. “We’re talking about whether young families can find stable, affordable homes in our biggest cities.”

Government Revenue

On paper, the numbers look compelling. Replacing the discount with full inclusion could inject billions into the budget. But there’s a risk of unintended consequences: if investor activity drops sharply, stamp duty revenues (which depend on transaction volumes) could fall instead.

“There needs to be a careful calibration,” cautions Dr. Mitchell. “Too abrupt a change could destabilise the housing market at a time when stability is needed most.”

Shareholders

One potential silver lining: eliminating the property-specific CGT advantage could make listed shares more attractive relative to bricks-and-mortar assets. Over time, this might encourage diversification and reduce speculative property flipping.

Immediate Effects: Signs the Tide Is Turning

Even before final decisions are made, the signals are clear:

• Major brokerages are advising clients to reconsider long-term property strategies.
• Real estate forums are buzzing with discussions about timing sales before any reform kicks in.
• Political parties are positioning themselves—Labor leans toward reform; the Coalition remains cautious, warning of unintended consequences.

In Melbourne and Perth, some landlords have quietly raised rents by 5–10 per cent in recent months, citing “increasing regulatory uncertainty.” Others are exploring alternative investments, such as agricultural land or commercial properties with different tax treatments.

Meanwhile, tenant advocacy groups are stepping up lobbying efforts, arguing that any tax reform must include safeguards for renters, such as rent controls or increased social housing supply.

Future Outlook: What Happens Next?

With the 2026 federal budget due in May, all eyes are on Treasury and the Treasury benches. Expectations are high—but so is the complexity.

Key questions remain: - Will the discount be phased out gradually or abolished immediately? - Are there transitional provisions to protect existing investors? - Will the government pair this reform with measures to boost housing supply or support first-home buyers?

Some experts believe the government may opt for a compromise: keeping the discount for primary residences while applying stricter rules to investment properties. Another possibility is introducing a tiered system based on holding periods or asset value.

“History tells us that tax reforms rarely go smoothly,” says political analyst James Reid. “But given the scale of the housing challenge and the fiscal pressures facing the nation, bold action seems inevitable.”

Long-term, the outcome could reshape Australia’s wealth distribution. Home ownership rates have already fallen below 70 per cent for the first time in decades. If investment becomes less attractive, that trend may accelerate.

Conversely, a well-designed reform could free up capital for productive uses beyond real estate—spurring innovation, job creation, and broader economic resilience.

Conclusion: A Pivotal Moment for Housing Policy

What started as a routine budget discussion has quickly become one of the most consequential policy debates of the decade. The fate of Australia’s 50 per cent CGT discount isn’t just about numbers on a spreadsheet—it’s about who gets to call a house a home.

As the government weighs its options, one thing is certain: the path forward must balance fairness, fiscal responsibility, and the urgent need for affordable housing
