Federal budget 2026 capital gains tax today: property investors brace for major shake-up

Australia’s federal budget debate has turned sharply toward capital gains tax and negative gearing reforms, with Treasurer Jim Chalmers preparing what could become the biggest property tax overhaul in decades. The changes are being framed as a way to help first-home buyers break into the market, but landlords, investors and renters are already arguing over who will end up paying the real price.

For Australians trying to buy their first home, the government says the reforms could open the door for around 75,000 additional buyers. Meanwhile, the property industry is warning of rent spikes and investor pullbacks if the tax settings change too aggressively.

The Full Story

The debate exploded ahead of the 2026 federal budget after reports confirmed the government was seriously examining changes to capital gains tax concessions and negative gearing rules for investors. These tax settings have been politically radioactive for years. Labor backed away from similar reforms after the 2019 election loss, but rising housing costs and worsening affordability have pushed the issue back onto centre stage.

Under the current system, investors can offset property losses against taxable income through negative gearing, while also receiving discounted capital gains tax rates when they eventually sell. Critics argue the setup encourages speculative investment and pushes prices beyond the reach of ordinary buyers.

Now the government appears ready to test that argument again. Treasury estimates suggest reforms could improve access for tens of thousands of first-home buyers, particularly younger Australians locked out of Sydney, Melbourne and Brisbane markets. If you’re following this closely, you’ll know housing affordability has become one of the defining political issues of the decade.

Not everyone is buying the pitch, though. Property groups and some real estate executives say changing investor tax settings could backfire by discouraging new housing supply. One warning suggested rents could jump by as much as 30 per cent if investors leave the market in large numbers.

Others point to Victoria as evidence that the impact may not be so dramatic. Analysts comparing recent state-level investor tax changes argue rental supply did not collapse and rents did not surge solely because of tax adjustments. That’s where things get a bit messy — because both sides are using different slices of the housing market to make their case.

Capital gains tax

A tax applied to profits made when selling assets like investment properties or shares.

Negative gearing

A system allowing investors to deduct investment losses from taxable income.

Housing supply

The total number of homes available for sale or rent in the market.

Who's Involved

Jim Chalmers, Australia’s Treasurer, is leading the budget strategy and defending the need for difficult economic decisions as housing affordability dominates public debate.

Bill Shorten, the former Labor leader who previously took negative gearing reform to an election, has publicly backed renewed action, arguing the housing system now unfairly favours investors over younger Australians.

Property industry groups, landlords and major real estate executives are lobbying hard against large-scale changes. Some investors insist removing tax concessions will discourage rental property investment and worsen shortages.

Meanwhile, economists and housing advocates supporting reform argue the current tax system inflates demand rather than increasing construction. Their position is that incentives should favour new housing supply instead of existing property speculation.

“The time has come” for governments to revisit housing tax concessions.

By the Numbers

75,000 — estimated number of additional first-home buyers the government believes could enter the market after reforms.

30% — potential rent increase warned about by some real estate industry figures if investor activity drops sharply.

50% — the current capital gains tax discount many Australian investors receive on assets held longer than a year.

$60 million — size of one landlord portfolio highlighted in the broader debate over whether negative gearing is essential for investment.

What This Means

For Australians already struggling with rent or mortgage costs, the debate cuts straight into daily life. Younger buyers have watched prices race ahead of wages for years, especially in major cities where even modest homes now sit far beyond average incomes.

What’s interesting is this isn’t just about tax anymore. It’s become a broader argument over who the housing market is built for. Investors say they provide rental supply. Critics counter that tax concessions have fuelled competition for existing homes instead of encouraging enough new construction.

There’s also a political risk here. Labor walked away bruised after similar proposals in 2019. But with affordability now far worse than it was back then, the government appears convinced voters are more willing to consider structural reform. Fair dinkum, it’s hard to ignore the pressure when younger Australians are spending record portions of income just to keep a roof over their heads.

For readers in Australia, the practical question is simple: will these reforms actually make homes cheaper, or just shift costs somewhere else? Economists remain divided, and the answer likely depends on how aggressively the changes are designed.

What to Expect

The federal budget is expected to reveal whether the government proceeds with full-scale tax reform or opts for smaller adjustments designed to avoid political backlash.

Investors, renters and first-home buyers will also be watching for transition rules. Any grandfathering arrangements for existing investors could heavily shape market reaction.

You might be wondering whether immediate property price falls are coming. Most analysts expect any impact to unfold gradually rather than overnight, especially if reforms are phased in over several years.

FAQ

What is changing with capital gains tax in Australia?

The government is considering reducing or restructuring tax concessions linked to investment properties. That could include changes to the current 50 per cent discount investors receive on long-term capital gains.

Will negative gearing be scrapped completely?

No final decision has been announced. Current discussions range from limiting deductions on existing homes to changing how losses can be claimed against income.

How could this affect Australian renters?

Supporters say reforms could cool housing demand and improve affordability over time. Critics argue some landlords may leave the market, potentially tightening rental supply in certain suburbs.

Why is the government focusing on housing tax reform now?

Housing affordability has worsened sharply across Australia, especially for younger buyers. Rising prices, higher interest rates and rental stress have increased pressure on Canberra to act.

Could house prices actually fall?

Some economists believe reduced investor demand could slow price growth or trigger modest declines in parts of the market. Others expect only limited impact because population growth and housing shortages remain strong.

How does this affect first-home buyers?

The government estimates reforms could help around 75,000 additional Australians buy their first property. The idea is to reduce investor competition for existing homes and improve buyer access.
