Why Housing Tax Reform Is the Hottest Topic in Australia Right Now
Australia is in the grip of one of its worst housing affordability crises in living memory. National median house prices hover around $835,000, rental vacancy rates sit at a tight 1.4% nationally, and more than 30% of Australians now rent — many of whom feel permanently locked out of home ownership. Against this backdrop, the question of how Australia taxes housing has never been more urgent.
The debate covers three main pillars: Capital Gains Tax (CGT) discounts for investors, negative gearing deductions, and the ongoing push to replace state-level stamp duty with a broad land tax. As of March 2026, none of these have been reformed by the federal government — but the pressure has rarely been greater, with a Senate inquiry, Greens political deals, and a federal budget due in May 2026 all converging at the same time.
This blog breaks down everything you need to know: how the current system works, what reforms are being proposed, who wins and loses under each scenario, and where things stand right now.
Key context: Australia’s residential property market is valued at approximately $12 trillion. Of this, around $4.5 trillion represents price growth since 2020 alone — making the tax treatment of housing wealth one of the most consequential policy questions in the country.
PART 1: UNDERSTANDING THE CURRENT TAX SYSTEM
1. Capital Gains Tax (CGT) — The 50% Discount Explained
Capital Gains Tax is not a separate tax in Australia — it is part of the income tax system. When you sell an asset for more than you paid for it, the profit (the ‘capital gain’) is added to your assessable income for the year and taxed at your marginal rate.
The key concession that has attracted controversy is the 50% CGT discount, introduced by the Howard Government in 1999. Under this rule, if an individual holds an asset — including an investment property or shares — for more than 12 months before selling it, they only pay tax on half of the capital gain. Complying superannuation funds receive a one-third discount instead.
This was originally designed to simplify the system and account for inflation (replacing a more complex indexation method). In practice, however, it has become one of the most valuable tax concessions available to Australian investors, particularly those in higher income brackets.
CGT Discount at a Glance
| Taxpayer Type | CGT Discount | Effective Tax Rate (Top Bracket) |
|---|---|---|
| Individual / Trust | 50% | ~23.5% on capital gain |
| Complying Super Fund | 33.3% | ~10% on capital gain |
| Company | None | 30% on full capital gain |
| Owner-Occupier (Primary Residence) | 100% Exempt | Nil — no CGT payable |
The owner-occupied primary residence exemption is the most generous concession of all. Treasury estimates the government forgoes more than $50 billion per year in tax revenue by exempting family homes from CGT. This is rarely discussed in the debate because taxing the family home is politically toxic — but economists argue it is the single largest housing-related distortion in the tax system.
2. Negative Gearing — What It Is and How It Works
Negative gearing occurs when the costs of owning an investment property — including mortgage interest, maintenance, insurance, council rates, and property management fees — exceed the rental income it generates. The investor is therefore making a net loss on the property.
Under Australia’s tax rules, this net rental loss can be deducted from the investor’s other assessable income — typically their salary — reducing their overall tax bill. This is not a special concession unique to property; it is a basic principle of income tax law. However, combined with the CGT discount, it creates a powerful two-part incentive: investors can claim tax deductions on losses now while paying reduced tax on capital gains when they eventually sell.
How Negative Gearing Works — A Simple Example
| Item | Amount |
|---|---|
| Annual rental income | $28,000 |
| Annual mortgage interest | $38,000 |
| Other costs (maintenance, rates, fees) | $6,000 |
| Net rental loss (negative gearing) | -$16,000 |
| Investor’s salary | $120,000 |
| Taxable income after rental loss | $104,000 |
| Estimated tax saving (at 37% bracket) | ~$5,920 per year |
In 2020-21, over 2.2 million Australians declared rental property income or costs — around 14.8% of all taxpayers. Of those, just over one million (47.9%) declared a net loss, meaning they were negatively geared. Research estimates that negative gearing reduced Australia’s tax revenue by approximately $3.7 billion in 2014-15, with half of that benefit flowing to households in the top 20% of incomes.
3. Stamp Duty — The Upfront Tax Blocking Mobility
Stamp duty (officially called ‘land transfer duty’ in most states) is a state and territory tax charged when property changes hands. It is calculated as a percentage of the purchase price and must be paid upfront at settlement. The rates vary significantly by state and can add tens of thousands of dollars to the cost of buying a home.
For example, on an $835,000 property purchase in Victoria, stamp duty alone would cost approximately $45,000 — on top of the deposit, mortgage insurance, and legal fees. This represents a major barrier to entry for first home buyers and is widely criticised by economists as economically inefficient because it discourages people from moving to more suitable housing as their life circumstances change.
Stamp Duty on an $835,000 Purchase by State (2026 estimates)
| State / Territory | Stamp Duty (est.) | % of Purchase Price |
|---|---|---|
| New South Wales | $33,340 | 3.99% |
| Victoria | $44,870 | 5.37% |
| Queensland | $21,850 | 2.62% |
| Western Australia | $33,435 | 4.00% |
| South Australia | $38,575 | 4.62% |
| ACT (transitioning to land tax) | $18,200* | 2.18%* |
ACT figures are lower due to their ongoing 20-year transition away from stamp duty toward annual rates-based property tax, which commenced in 2012.
PART 2: WHAT’S CURRENTLY BEING DEBATED AND PROPOSED
4. The Senate Inquiry into the CGT Discount — March 2026 Report
One of the most significant recent developments is the Senate Select Committee on the Operation of the Capital Gains Tax Discount, which was established on 4 November 2025 with a final report due on 17 March 2026. The committee was tasked with examining CGT’s impact on housing affordability, productivity, and income distribution across the economy.
The majority report found that the design of the CGT discount has the potential to distort investment allocation across the economy and contributes to housing affordability challenges. However, the committee stopped short of recommending abolition, recognising the complexity of any transition and the fact that the discount applies to shares and other assets — not just property.
Domain chief economist Dr Nicola Powell cautioned that changes to the CGT discount alone will not fix housing affordability, arguing that the government also needs to tackle supply, rethink stamp duty, and make better use of the existing housing stock.
5. Negative Gearing — Where Does It Stand in March 2026?
As of today (23 March 2026), the Albanese Labor Government has not moved to change negative gearing or the CGT discount. This is a politically sensitive retreat. Labor took a policy to the 2019 federal election to limit negative gearing to new properties only and reduce the CGT discount from 50% to 25%. That policy was widely seen as a factor in Labor’s unexpected election loss that year. Since winning government in 2022, Labor has carefully avoided revisiting the issue.
The government’s focus in early 2026 has been on superannuation tax reform — specifically the Division 296 super tax on balances above $3 million — and cost-of-living relief measures. However, as part of securing Greens support for the Division 296 legislation in March 2026, Labor agreed to further tax reform discussions, keeping the pressure on for the May 2026 budget.
The Greens continue to advocate for abolishing both negative gearing and the CGT discount entirely, arguing the concessions overwhelmingly benefit wealthy Australians at the expense of renters and aspiring home buyers.
Key political context: Treasurer Jim Chalmers has declined to rule out options for CGT reform ahead of the May 2026 federal budget, signalling the government is at least open to change — even if it has not yet committed to specific measures.
6. What Reform Proposals Are on the Table?
Several credible reform proposals have emerged from advocacy groups, research institutes, and parliamentary inquiries. Here is a summary of the main options being discussed:
Option A — Reduce the CGT Discount (ACOSS/Grattan Model)
The Australian Council of Social Service (ACOSS) has recommended reducing the 50% CGT discount for individuals and trusts to 25% over five years, by 5% per year, starting 1 July 2025. This would raise approximately $1.2 billion in 2026-27, rising substantially in later years. Revenue would be directed toward social and affordable housing investment.
Option B — Cap Negative Gearing Deductions
ACOSS also recommends restricting negative gearing deductions so rental losses can only be offset against income from the same class of investments (e.g. rental income or capital gains from property) — not against salary and wages. New investments would be subject to this rule immediately. For existing negatively geared properties, the proportion of losses claimable against other income would be progressively reduced to zero over five years, raising approximately $2.3 billion in 2026-27.
Option C — Gradual Reform Over a Decade (AHURI/Grattan Approach)
The Australian Housing and Urban Research Institute (AHURI) and Grattan Institute argue the most politically and economically prudent approach is gradual, incremental change over 10 years or more — reducing the CGT discount from 50% to 30%, and introducing a cap on negative gearing deductions starting at $20,000 and reducing by $1,500 per year. This minimises disruption to housing markets and household finances while raising meaningful revenue over time.
Option D — Property Council’s Counter-Position (No Tax Tightening)
The Property Council of Australia has strongly opposed any reduction to the CGT discount or negative gearing, arguing that the country already faces a structural housing shortage of 1.3 million homes built since 2000, and that hiking taxes on investors will deter new housing supply, push rents higher, and harm the very people it is intended to help. CEO Mike Zorbas has warned that reducing the CGT discount to 33% while capping negative gearing to two properties could discourage investment and ‘hammer supply’ of new homes.
Proposal Comparison Summary
| Proposal | CGT Change | Neg. Gearing Change | Budget Impact (2026-27) | Support Base |
|---|---|---|---|---|
| ACOSS / Greens | 50% to 25% | Losses ring-fenced | $3.5B+ | Welfare, housing groups |
| Grattan / AHURI | 50% to 30% | Cap at $20K, taper | $1-2B | Academic / think tanks |
| Property Council | No change | No change | Nil | Property industry |
| Labor (stated) | Under review | No announcement | TBD | Government |
| Greens | Abolish entirely | Abolish entirely | $5B+ | Greens party |
PART 3: STAMP DUTY VS LAND TAX — THE STATE-LEVEL BATTLE
7. The Case for Replacing Stamp Duty with Land Tax
Most economists agree that stamp duty is one of the most economically harmful taxes in Australia. It discourages people from selling and moving to housing that better matches their needs. Retirees stay in large family homes to avoid stamp duty on downsizing. Workers avoid moving to cities with better job opportunities because the transaction cost is too high. Young families can’t afford the upfront payment on top of a deposit.
The solution most economists support is replacing stamp duty with a broad annual land tax — a small annual levy on the value of land, paid by all property owners. This spreads the tax burden over time, reduces the barrier to buying, and is more efficient because it doesn’t discourage transactions.
Stamp Duty vs Land Tax — Key Differences
| Feature | Stamp Duty | Annual Land Tax |
|---|---|---|
| When paid | Once, at purchase | Every year |
| Who pays | Buyer only | All landowners |
| Amount | Large upfront sum (3-6% of price) | Small annual amount (0.3-0.5% of land value) |
| Effect on mobility | Discourages moving | Neutral — no transaction barrier |
| Economic efficiency | Highly inefficient | One of the most efficient taxes |
| Effect on housing supply | Reduces turnover | Encourages efficient land use |
| Political difficulty | Easy to keep (buyers pay once) | Hard to introduce (all owners pay annually) |
8. The ACT Model — Australia’s Only Live Example
The Australian Capital Territory (ACT) has been quietly demonstrating what this transition looks like in practice since 2012. The ACT embarked on a 20-year reform program to gradually phase out stamp duty and replace it with higher annual property rates. The transition has been incremental — a small annual reduction in stamp duty offset by a small annual increase in rates — giving households time to adjust and avoiding fiscal shocks for the territory government.
Early evidence from the ACT suggests the reform has improved housing market turnover and has not caused significant disruption to property values. It remains, however, the only Australian jurisdiction to have seriously implemented this model.
Victoria received $8.2 billion in land transfer duty in the 2023-24 budget year. For a state like Victoria to achieve revenue neutrality by moving to an annual land tax, it would need to levy approximately $1,293 per year on every residential, commercial, and agricultural property — a figure that rises over the transition decade but represents a fundamentally different way of funding government services.
Note on Victorian developments: In November 2025, the Victorian State Revenue Office issued a draft ruling that would impose stamp duty on adjustments of land tax at settlement for commercial property transactions above $10.4 million — representing a move in the opposite direction to reform and drawing criticism from tax practitioners.
PART 4: OTHER KEY REFORMS ALREADY UNDERWAY
9. Foreign Buyer Ban — Effective April 2025
One housing-related reform that has already been implemented is the two-year ban on foreign buyers purchasing existing dwellings, which came into force on 1 April 2025. The Albanese Government provided the ATO with $5.7 million to enforce the ban, along with $8.9 million to target land banking by foreign buyers to ensure vacant land is put to productive use.
The foreign resident withholding tax rules were also tightened from 1 January 2025: the withholding rate increased from 12.5% to 15%, and the previous $750,000 property value threshold was removed, meaning the rules now apply to all property sales regardless of price. All Australian residents selling property now need to obtain an ATO clearance certificate to avoid the withholding.
10. Build-to-Rent Tax Concessions — Refined in Budget 2025-26
The government refined its Build-to-Rent (BTR) tax concessions in the 2025-26 Budget to encourage institutional investment in purpose-built rental housing. The key changes include a reduced managed investment trust (MIT) withholding tax rate for eligible BTR projects, provided at least 10% of dwellings are made available as affordable tenancies.
Industry estimates suggest this will support the construction of around 80,000 new rental homes over the next decade, including 8,000 affordable homes. The BTR sector reached a record 6,000 new completions in 2025 (up from 4,660 in 2024), with over 20,000 approved units still in the pipeline for 2026. BTR still accounts for less than 1% of Australia’s housing stock, meaning the sector has significant room to grow.
11. Help to Buy Shared Equity Scheme — Expanded
The federal government has expanded the Help to Buy shared equity program with around $800 million in additional funding to lift property price and income caps, making the scheme accessible to more Australians. Under the program, the government provides an equity contribution of up to 40% of the purchase price, allowing eligible buyers to enter the market with a smaller deposit and a smaller mortgage. Approximately 40,000 Australian households are expected to benefit.
12. Housing Construction Apprenticeships — From July 2025
From 1 July 2025, eligible apprentices in housing construction occupations receive up to $10,000 in financial incentives over the course of their apprenticeships, under the new Housing Construction Apprenticeship stream. This is part of the government’s broader effort to address the skills shortage in the construction sector, which is limiting the pace of new home building.
PART 5: WHO WINS AND WHO LOSES UNDER REFORM SCENARIOS
13. Impact Analysis by Stakeholder Group
Tax reform always creates winners and losers. Below is a plain-language breakdown of how different groups are likely to fare under the main reform scenarios being discussed.
First Home Buyers and Aspiring Owners
First home buyers are the group most likely to benefit from housing tax reform. If CGT discounts and negative gearing are wound back, there is a strong argument — though contested — that investor demand for existing housing would moderate, reducing upward price pressure. Stamp duty reform to a land tax would directly reduce the upfront cost of purchasing, making entry into the market more achievable.
However, if reform results in investors exiting the rental market and rental supply shrinking, first home buyers who rent while saving for a deposit could face even higher rents in the short term.
Existing Investors (‘Mum and Dad’ Landlords)
Around 60% of Australia’s approximately 2 million small-scale residential investors — often described as ‘mum and dad’ landlords — would be largely unaffected by a $20,000 negative gearing cap, according to modelling. Only those with the largest rental losses would face meaningful change.
Under CGT discount reduction scenarios, investors who have held properties for many years and built up large unrealised gains would face significantly higher tax bills on eventual sale. This could also prompt a surge in selling before reform takes effect, potentially causing a short-term increase in housing supply.
Renters
The impact on renters is the most complex and debated aspect of any reform. Proponents of CGT and negative gearing reform argue these concessions artificially inflate property prices and reduce the number of homes available for owner-occupation, forcing more Australians to rent indefinitely. Reducing concessions, they argue, would rebalance the market toward owner-occupation.
Critics respond that existing rental supply largely depends on private landlords who rely on these concessions. If investors sell up or stop buying, rental supply tightens and rents rise. National vacancy rates are already at just 1.4%, with rentals in major cities extremely tight. Any reduction in landlord numbers in this environment carries real risk of higher rents.
High-Income Earners and Institutional Investors
The bulk of the financial benefit from negative gearing flows to higher-income earners who face higher marginal tax rates and therefore benefit more from deductions. Research consistently finds that around half of the total benefit from negative gearing goes to the top 20% of income earners. CGT discount reform would most impact those with large investment portfolios and high capital gains — again, typically higher-wealth households.
Summary: Winners and Losers by Reform Scenario
| Stakeholder | CGT Discount Cut | Negative Gearing Cap | Stamp Duty to Land Tax |
|---|---|---|---|
| First home buyers | Likely benefit (lower prices) | Likely benefit (lower prices) | Clear benefit (lower entry cost) |
| Renters (short term) | Risk of higher rents | Risk of higher rents | Neutral |
| Renters (long term) | Possible benefit | Possible benefit | Neutral to positive |
| Mum & dad investors (<$20K loss) | Moderate impact | No impact | Annual cost (land tax) |
| High-income investors | Significant tax increase | Reduced deductions | Annual cost (land tax) |
| Property developers | Uncertain — lower demand? | Uncertain | Positive (more turnover) |
| State/territory governments | Indirect effect only | Indirect effect only | Revenue transition risk |
PART 6: THE BIGGER PICTURE — WHAT THE DATA SAYS
14. Key Housing Market Statistics — March 2026
| Metric | Figure | Source / Note |
|---|---|---|
| National median house price | ~$835,000 | February 2026 |
| National rental vacancy rate | ~1.4% | SQM Research, early 2026 |
| Share of Australians who rent | ~30% | ABS estimate |
| Total residential property value | ~$12 trillion | RBA / CoreLogic |
| Price growth since 2020 | ~$4.5 trillion | CoreLogic estimate |
| Negatively geared property owners | ~1.06 million | ATO 2020-21 data |
| CGT revenue foregone (investors) | ~$6.84 billion/yr | 2016-17 estimate, Treasury |
| CGT revenue foregone (owner-occupiers) | >$50 billion/yr | Treasury estimate |
| Annual stamp duty revenue (Victoria alone) | $8.2 billion | 2023-24 Victorian Budget |
| BTR completions (2025) | ~6,000 units | Knight Frank forecast |
| BTR pipeline | >20,000 approved | BDO estimate, 2025 |
| Federal housing target (5 years) | 1.2 million new homes | National Housing Accord |
PART 7: WHAT HAPPENS NEXT
15. The May 2026 Federal Budget — The Key Date to Watch
The May 2026 Federal Budget is shaping up as the most significant decision point on housing tax reform in years. Treasurer Jim Chalmers has declined to rule out changes to the CGT discount, and media reporting in early 2026 suggested changes could be considered as part of the budget. The Senate CGT inquiry report, delivered on 17 March 2026, has added further political momentum.
The Greens secured commitments from Labor for further tax reform discussions as part of their support for the Division 296 super tax legislation in March 2026 — a significant political development that increases the likelihood of some form of CGT or negative gearing change being announced.
However, the government faces a difficult balancing act. It is acutely aware that housing tax reform contributed to Labor’s 2019 election defeat. The new parliament, in which Labor has a stronger majority, may give the government more room to act — but the politics remain delicate.
16. Expert Consensus — What Do the Economists Actually Think?
There is a broad consensus among economists that the current tax treatment of housing investment is distortionary — it encourages too much investment in housing relative to more productive assets, inflates prices, and exacerbates wealth inequality. The Productivity Commission, OECD, Reserve Bank, and most academic economists have at various points recommended reform.
Where economists disagree is on the sequencing and scale of change. Most favour gradual, phased reform rather than sudden change, and most argue CGT and negative gearing reform must be accompanied by supply-side measures — more land release, faster planning approvals, construction industry reform — to be effective. Tax reform alone will not build homes.
The Housing Industry Association put it directly: ‘The priority for governments must be to pull out all stops to support new home building. This involves focusing on the cost of development and reducing taxes on home building — not increasing them.’
The bottom line: Reforming Australia’s housing tax system is widely regarded as necessary and overdue. But the political barriers are formidable, the trade-offs are real, and the timing — with a housing shortage already acute — makes the stakes unusually high. The May 2026 budget will tell us whether the Albanese government has the appetite to act.
Key Takeaways
- Australia’s housing affordability crisis is driven by a mix of tax concessions (CGT discount, negative gearing), stamp duty, planning constraints, and construction capacity — not by any single factor.
- The 50% CGT discount and negative gearing collectively reduce federal tax revenue by billions annually and disproportionately benefit higher-income households.
- As of 23 March 2026, no changes to CGT or negative gearing have been legislated — but the May 2026 budget is the most likely moment for reform announcements.
- Stamp duty reform to a broad land tax is supported by most economists but remains politically challenging outside the ACT, which has been transitioning since 2012.
- Already-enacted reforms include: the foreign buyer ban (from April 2025), tightened foreign resident withholding tax (from January 2025), Build-to-Rent concessions, and the Help to Buy shared equity scheme expansion.
- The risk of any reform reducing rental supply in an already-tight market (1.4% vacancy) is a genuine constraint that policymakers must navigate carefully.
- The national 1.2 million homes target over five years requires not just tax reform but substantial investment in supply, planning reform, and construction workforce expansion.
