What it means
Some investments lose money on purpose, and negative gearing is the deliberate holding of a property, or another asset, whose rent does not cover interest and running costs, in exchange for expected capital growth. The maths only works through tax, since where the law allows, the rental loss offsets salary or business income, cutting the investor's tax bill while the asset, hopefully, appreciates.
Australia made the term famous, as the Australian Taxation Office's rental property guidance lets landlords deduct eligible expenses against rental income, with net rental losses generally deductible against other assessable income. Depreciation deductions deepen the paper loss, because building and fittings write-offs can turn a small cash shortfall into a large tax loss, which is why two identical flats can carry very differently.
The bet has three legs: capital growth must eventually exceed the accumulated losses, tax savings must soften the bleeding, and the investor must service the shortfall every month without breaking. The risks are cyclical, as rising interest rates widen the loss, flat property prices postpone the payoff, and tax rules can change, as periodic Australian reform debates remind investors.
The strategy shapes whole markets. Critics argue it inflates housing demand and prices, while defenders say it supports rental supply, and the argument recurs whenever affordability worsens.
For the tenant, the strategy is invisible but present, because the landlord's arithmetic shapes the rent level and the property's upkeep, whatever the tax position behind the scenes. For a business owner tempted by the pitch, discipline starts with the honest number: write down the monthly shortfall you can carry for five flat years, because the growth that rescues the strategy is a hope, not a term sheet.
Portfolio fit deserves a hard look, since a negatively geared property is a concentrated, leveraged bet on one postcode, and the tax benefit never diversifies that risk.
In practice
Real-world examples.
Example
A landlord's rental loss reduces her taxable salary, cutting her annual tax bill while she waits for the suburb to gentrify. Her adviser recalculates the position after every rate move.
Example
An investor abandons a negatively geared flat when rates reset and the monthly shortfall doubles beyond his buffer. The buffer, not the tax refund, was the real protection.
Example
A tax adviser models a client's gearing plan under flat prices for five years before letting her sign, showing the total carry cost in one number. The five-year carry figure ends more deals than any inspection. Discipline beats enthusiasm at the spreadsheet.
Formula
Calculation
Net rental result = rent - (interest + expenses). Rent of $24,000 against interest of $30,000 and costs of $6,000 gives a $12,000 loss, which at a 37% marginal rate returns about $4,440 in tax, leaving $7,560 of real annual pain to carry. Growth must outrun the cumulative carry.
Suppose the interest comes from a $600,000 loan at 5%. The after-tax carry is $7,560 / 12 = $630 a month, or $7,560 x 5 = $37,800 over five years. The property must therefore rise by at least $37,800 / $600,000 = 6.3% in total over those five years just to repay the carry, before selling costs.Case study
Seen in the real world.
In this illustrative fictional case, Priya, an engineer in Sydney, buys a unit whose rent falls $9,000 short of its costs each year. Her tax refund recovers roughly a third, and the suburb grows 5 percent annually for six years, more than repaying the shortfall at sale. Her friend with the identical plan in a flat mining town sells at a loss after carrying the same shortfall, and only the tax refund softened the outcome. The comparison convinces her that the strategy is geography with a tax wrapper.
The illustrative arithmetic is revealing. A refund of a third leaves $6,000 a year of real cost, or $36,000 over six years. On a $600,000 unit, 5% annual growth for six years adds about $204,000, so Priya comes out well ahead, while her friend's flat price leaves the $36,000 of carry, plus selling costs, as a pure loss.
Watch out
Common mistakes.
- Counting the tax refund as profit, when the deduction returns only a fraction of the loss, and every refunded dollar still cost you more than a dollar of real cash. After-tax cash flow is the honest ledger.
- Assuming capital growth is guaranteed, when flat or falling prices turn a tax strategy into a slow, subsidised loss with no exit.
- Ignoring policy risk, when the tax treatment that justifies the strategy is a political football, and rule changes can strand the economics.
Questions
People also ask.
What is negative gearing?
Holding a borrowed investment whose costs exceed its income, producing a running loss. Where tax law permits, that loss offsets other income, and investors accept the bleed for expected capital growth. Positive gearing is the income-producing mirror. The loss is deliberate, not accidental.
Where is negative gearing common?
Australia is the best-known case, where the Taxation Office lets net rental losses reduce other taxable income. New Zealand had similar rules before tightening them for residential property.
When does it make sense?
Only when expected growth plausibly exceeds total losses and tax savings, and the investor can fund the monthly shortfall through bad years. Without both, it is subsidised speculation. Cash reserves decide who survives the wait.
