Negative gearing is one of Australia's most talked-about tax strategies. It occurs when your investment property expenses (loan interest, maintenance, depreciation) exceed rental income — creating a 'loss' that reduces your taxable income and therefore your tax bill. While it doesn't make money on its own, the tax benefit combined with potential capital growth and rental income growth can create long-term wealth. This calculator shows you the real numbers.

Real-World Examples

Standard Negative Gearing

Jenny buys a $650,000 unit, borrows $520,000 at 6.2%, rents for $550/week. Expenses: $9,000/year. Depreciation: $10,000/year. Marginal rate: 37%.

Annual rent: $28,600. Interest: $32,240. Expenses: $9,000. Depreciation: $10,000. Total costs: $51,240. Net loss: $22,640. Tax saving at 37%: $8,377/year ($161/week). After-tax cost of holding: $14,263/year ($274/week).

Positively Geared Property

Same property but in a regional area: $400,000 purchase, $320,000 loan at 6.2%, $450/week rent.

Annual rent: $23,400. Interest: $19,840. Expenses: $6,000. Depreciation: $6,000. Total costs: $31,840. Net loss: $8,440. At 37% rate: $3,123 tax saving. If rates drop or rent rises, this property could flip to positive gearing.

Frequently Asked Questions

Glossary

Negative Gearing
When the expenses of an investment property exceed the rental income, creating a net loss. This loss can be deducted from your other income, reducing your overall tax.
Depreciation
A non-cash tax deduction for the wear and tear of a property's structure (Division 43) and fixtures/fittings (Division 40). Must be calculated by a qualified quantity surveyor.
Positive Gearing
When rental income exceeds all expenses. The property makes a profit, which is added to your taxable income. Often occurs when the loan is paid down or rents increase.
Cost Base
The total cost of acquiring a property including purchase price, stamp duty, legal fees, and capital improvements. Used to calculate capital gain when selling.

Key Information

  • Negative gearing means your property runs at a loss — this loss is deductible against your other income (salary, etc.).
  • The higher your marginal tax rate, the greater the tax benefit. At 45%, every $1 of loss saves you 45c in tax.
  • Depreciation is a non-cash deduction — you claim wear and tear without spending money. New properties offer the best depreciation.
  • The ATO closely scrutinises rental property claims — keep meticulous records of ALL expenses.

Pro Tips

  • Get a quantity surveyor depreciation report ($600-$800) — it typically identifies $5,000-$15,000 in annual depreciation claims, paying for itself many times over.
  • Interest is only deductible on the portion of the loan used for the investment — don't mix with personal borrowing in the same loan.
  • Pre-pay interest before 30 June to bring forward deductions — commonly used by high earners.
  • Track your occupancy rate — if vacant for extended periods, the ATO may adjust your claims.

Avoid These Mistakes

  • Buying a property solely for tax benefits — the property must still make financial sense. A bad investment with good tax deductions is still a bad investment.
  • Not getting a depreciation schedule for properties built after 1985 — you're leaving thousands in deductions on the table.
  • Claiming travel to inspect rental property (no longer deductible since 2017) or personal use portion of a holiday home.
  • Forgetting that when you sell, depreciation claimed is added back to your capital gain (CGT wash-up).
