Negative gearing comes up constantly in Australian property and tax conversations, and it's routinely oversimplified into "a tax trick for property investors." The actual mechanism is simpler, and the actual trade-off is more important, than that framing suggests. This is part of a wider guide to property and debt on Snowball Invest.
Quick answer
Negative gearing happens when the costs of owning an investment property, mainly loan interest, exceed the rental income it earns, creating a loss. Under Australian tax law, that loss can be deducted against your other income, like your salary, reducing your tax bill. It reduces the real cost of the loss, it doesn't eliminate it.

📉 What negative gearing actually means
"Gearing" just means borrowing to invest. A property is negatively geared when the rental income it earns is less than the deductible costs of holding it, mainly loan interest, but also things like property management fees, council rates, and depreciation. The result is a net rental loss for that financial year.
Under the ATO's rules, that loss isn't just absorbed, it can be deducted against your other assessable income, salary, wages, or business income, reducing your overall taxable income for the year.
🧮 A worked example
Someone earning $130,000 a year owns a rental property that runs at a $15,000 annual loss (rent received minus interest and other costs). That loss reduces their taxable income to $115,000. At a 37% marginal tax rate, that saves roughly $5,550 in tax, they're still $9,450 out of pocket for the year, the deduction softens the loss, it doesn't erase it.
🤔 Why investors actually do it
Nobody sets out to lose money every year forever. The strategy only makes sense if the investor expects the property's value to grow enough over time that the eventual capital gain, when sold, more than makes up for the losses accumulated along the way. It's a bet on long-term capital growth, financed partly by a tax-reduced annual loss in the meantime.
That means negative gearing isn't a strategy in itself, it's a side effect of how a leveraged property purchase is often structured in its early years, particularly while the loan balance and interest costs are highest relative to rental income. Many investors get there by using equity in an existing property rather than saving a deposit from scratch.
📊 How common it actually is, in real numbers
🎯 The essential: Around 1.1 million Australians are running a negatively geared property, collectively claiming over $54 billion in deductions in a single year.
This isn't a niche or marginal tax position, ATO taxation statistics show just over 2.26 million individuals reported an interest in a rental property in the most recent full year of data, and close to half of them, around 1.1 million people, were running at a net rental loss, meaning they were negatively geared. Collectively, those investors claimed roughly $54.5 billion in rental deductions that year, interest, maintenance, council rates and depreciation combined.
That $54.5 billion figure is total deductions claimed, not the actual cost to the federal budget, the real reduction in tax revenue is smaller, since it depends on each individual's own marginal tax rate applied to their share of that loss, not the full deduction amount. Still, the scale explains why negative gearing periodically becomes a live political issue, it's a structural feature of how well over a million Australians hold investment property, not a rare tax-planning trick used by a small handful of investors.
⚠️ The risk that gets glossed over
The whole strategy depends on an assumption that isn't guaranteed: that the property's value will rise enough, eventually, to offset years of real, out-of-pocket losses. If growth is slower than expected, or the property is sold during a downturn, an investor can end up having funded years of losses without the capital gain ever fully making up for them.
When that eventual sale does happen, the capital gains tax owed on the profit is the other half of the equation worth planning for, not just the annual deduction.
⚖️ Positive vs negative gearing
| Negative gearing | Positive gearing | |
|---|---|---|
| Rental income vs costs | Income is less than costs | Income is more than costs |
| Cash flow | Out-of-pocket loss each year | Extra income each year |
| Tax effect | Loss reduces your taxable income | Extra income is added to your taxable income |
| Typical bet | Relies on future capital growth | Relies on strong, reliable rental yield |
Whichever direction a property leans, the eventual tax bill on selling it is worth understanding well before that day comes.

❓ Frequently asked questions
Is negative gearing a special tax break just for property investors?
+
No, it's a general tax principle: a loss from an income-producing investment can offset your other taxable income. It's not a unique property loophole, it just gets talked about mostly in that context because of how common geared property investment is in Australia.
Does negative gearing mean the property is a bad investment?
+
Not necessarily, it means the property is running at a cash flow loss right now. Investors accept that loss expecting the property's value to grow enough over time that the eventual capital gain outweighs the accumulated losses, though that outcome isn't guaranteed.
Does the tax deduction cover the whole loss?
+
No, it reduces your tax bill by your marginal rate applied to the loss, it doesn't refund the loss itself. A $10,000 loss at a 32.5% marginal rate saves you $3,250 in tax, you're still $6,750 out of pocket.
Do you need a mortgage to negatively gear a property?
+
In practice almost always, since the interest on the loan is usually the single largest deductible expense that pushes a rental property into a loss in the first place. A property bought outright is far less likely to run at a loss.
Does negative gearing only apply to property?
+
No, the same principle applies to any borrowed money used to produce income, including shares or ETFs bought with a margin loan. The ATO does scrutinise negatively geared share portfolios more closely to confirm there's a genuine expectation of income, not just a tax angle.
