Tax overhaul on property investments set to temper Australia’s red-hot housing market

Government modelling signals a short-term slowdown in price growth as reforms target negative gearing and capital gains discounts

By Priya Menon

The Australian government is proposing sweeping changes to the taxation of residential property investments that Treasury modelling indicates would shave roughly two percentage points off house price growth over a short period. The measures - restricting negative gearing to newly built homes and removing existing capital gains tax discounts - are intended to rebalance ownership and encourage investment in new supply, though they carry political risk and uncertainty over how quickly supply will respond.

Tax overhaul on property investments set to temper Australia’s red-hot housing market

Key Points

  • Treasury modelling indicates reforms would lower house price growth by about two percentage points "over a couple of years" compared with no tax change; annual home price growth since 2000 averaged 6% - impacts housing and mortgage markets.
  • Proposed measures restrict negative gearing tax deductions to new builds and remove current capital gains tax discounts - affects property investors, construction sector, and housing supply.
  • Labor government advancing the package amid a strong parliamentary majority and rising cost of living concerns; generational voting changes (Generations Y and Z are 43% of 18 million enrolled voters) are influencing policy priorities - political and social implications for housing policy.

Australia’s federal government has put forward an ambitious package of tax changes aimed squarely at property investment, saying those measures should ease some of the immediate pressure on what remains one of the world’s least affordable housing markets.

Budget documents released on Tuesday said Treasury modelling expected house prices to increase by around two percentage points less "over a couple of years" than they would have if tax policy remained unchanged. The papers noted that, by comparison, annual home price growth since 2000 has averaged 6%.

The centre-left Labor government’s proposals would narrow the availability of tax deductions for so-called negatively geared properties to new residential construction only, and abolish the current discounts applied to capital gains tax for property investors. The reforms are presented as structural measures designed to reshape incentives within the housing investment market.

Tax changes targeting property investment have historically been politically sensitive. The budget documents acknowledge that a prior attempt to alter these tax settings contributed to an electoral loss for the Labor party seven years ago. Despite that history, Prime Minister Anthony Albanese - who secured a second term with a large parliamentary majority last year - is advancing the package as cost of living concerns have risen to the top of the political agenda.

"These changes will level the playing field for workers and first home buyers, and support investment in productive assets, including new housing supply," Treasurer Jim Chalmers said in his budget speech to parliament.

Negative gearing has been a core feature of Australia’s property investment landscape for around 25 years, permitting investors to offset operating losses against other income and to benefit from lower effective tax on capital gains when assets are sold. Critics have long argued that these tax concessions have concentrated homeownership among older, wealthier Australians who invested savings in rental properties, contributing to higher prices and reduced affordability for younger buyers.

Demographic and political shifts add context to the reforms. Generations Y and Z now make up 43% of Australia’s 18 million enrolled voters, creating a sizable electoral cohort pressing for changes to housing policy and suburban development norms.

Property values have climbed more than 40% over the past five years to record levels, driven in part by a post-pandemic surge in migration and a persistent shortage of available homes. The government documents also note that recent interest rate increases have moderated price gains to some extent.


As the reforms move through the political process, the Treasury’s modelling and the government’s stated objective are to shift investment toward newly built housing and reduce incentives for holding existing properties solely for tax advantages. How quickly those incentives translate into additional housing supply remains unclear in the documents.

Risks

  • Political backlash remains a real risk - past attempts to change property tax rules have cost the Labor party an election, so voter response could affect the reforms' durability - impacts political landscape and policy continuity.
  • The short-term effect on prices is modelled as a temporary reduction in growth rather than a full correction, leaving uncertainty about medium-term market dynamics and investor behaviour - affects housing and mortgage markets.
  • It is unclear how rapidly or effectively the reforms will stimulate new housing supply; if supply response is slow, affordability pressures could persist despite the tax changes - impacts construction and residential development sectors.
