Governments have three broad ways to tax a population.
They can tax directly, by increasing the burden on workers, businesses and investors.
They can borrow and spend, which is ultimately a tax on future generations.
And they can tax indirectly through inflation, by expanding spending and competing with private buyers for the same limited pool of goods, services, labour and materials.
Right now, Australians are being squeezed from all three directions.
Against that backdrop, the latest discussion around tax reform should concern property investors. Reported changes to negative gearing and capital gains tax would materially alter the investment equation, particularly if the objective is to raise an additional $15 billion in FY2027 and $24 billion per annum by FY2036.
There are other ways to find savings.
The Federal Government could take a harder look at the size and cost of the public service. It could address the well-documented integrity, eligibility and cost-control issues within the NDIS. It could apply a sharper lens to defence spending and the broader bureaucracy.
Instead, the likely path appears to be a heavier tax burden on one of Australia’s primary wealth-creation engines: property.
The problem with taxing property investors harder
Property investment works because private investors take risk.
They take on debt. They accept short-term cash flow pressure. They absorb maintenance, vacancy, interest rate movements, insurance, land tax, compliance costs and market risk. In return, they seek long-term capital growth, rental growth and some tax efficiency along the way.
If government reduces the after-tax reward for taking that risk, the lost return has to be recovered somewhere.
That generally means one of three outcomes:
• Lower purchase prices, as investors demand a sharper entry point to compensate for reduced tax benefits. This may sound helpful for first-home buyers, but it also places more pressure on the same entry-level bracket where competition is already strongest.
• Higher rents, as investors seek to recover increased costs from tenants where the market allows.
• Longer holding periods, as investors delay selling because the tax consequences become less attractive.
None of these outcomes clearly improves housing affordability. In fact, the risk is the opposite: less liquidity, fewer listings, weaker investor participation and further pressure on rental supply.
Where the impact would be felt most
Residential property would be the most exposed sector.
Its appeal has historically been built around a combination of long-term capital growth, negative gearing and preferential capital gains tax treatment. If those settings are changed, the impact would be felt most sharply in low-yield, investor-heavy parts of the market.
The most vulnerable assets would likely include:
• Low-yield apartments where capital growth is already limited.
• Investor-heavy suburbs where demand is more financially driven than emotionally driven.
• Properties with weak land content and limited scarcity value.
• Assets relying heavily on tax efficiency rather than strong underlying fundamentals.
Commercial property may be less directly affected because it is generally priced more transparently off income, lease quality, tenant covenant, outgoings, yield and rental growth.
However, it would not be immune.
Speculative land banking would likely become less attractive. Developers could also be affected if investor demand weakens, particularly in projects that rely on investor pre-sales or capital recycling.
The unintended consequences
The core issue is that governments often assume investors will behave the same way after tax changes as they did before them.
They will not.
If the tax treatment becomes less attractive, investors may hold assets longer, sell less frequently, buy more selectively or shift capital elsewhere. Others will simply increase the return they require before they are prepared to buy.
That means fewer transactions, less liquidity and potentially less private capital flowing into housing supply.
At a time when Australia is already facing a chronic housing shortage, it is difficult to see how discouraging private investment improves the supply side of the equation.
The risk is that government collects less revenue than expected, renters face more pressure, investors become more cautious and the housing market becomes even harder to navigate.
Grandfathering matters, but precedent matters more. The key detail will be whether any changes are grandfathered.
If existing investors are protected, the immediate market impact may be softer. If changes apply more broadly, the adjustment could be more significant.
But the bigger issue is precedent.
Once a new tax framework is introduced, it becomes easier to expand over time. What begins as a mild reform can later become a larger revenue lever, particularly when government spending continues to rise and budget pressures remain.
The takeaway for investors - This does not mean property stops being a strong wealth-creation vehicle.
Australia still has a structural housing shortage, high migration, limited supply, expensive construction, infrastructure-led growth corridors and a deep cultural preference for property ownership.
But tax changes would make property investing more specialised.
The easy version of property investment may be ending. The next phase will require better asset selection, sharper due diligence, stronger suburb selection, clearer yield analysis and a deeper understanding of how tax, cash flow, land value, scarcity and tenant demand interact.
In the absence of a compelling alternative, property will likely remain one of Australia’s primary wealth-creation vehicles.
But if government keeps plucking the property goose, investors will need to be far more selective about which goose they buy.
