Negative gearing in Australia refers to an investment property arrangement where the interest and other property expenses exceed the rental income received, creating a net rental loss. This loss is deductible against the investor's other income — primarily salary or wages — reducing their overall taxable income and tax liability. When the property is eventually sold, the 50% Capital Gains Tax (CGT) discount applies to any capital gain if the asset was held for more than 12 months, which is the primary mechanism by which investors ultimately profit. Positive gearing, where rental income exceeds all expenses, is relatively uncommon in high-cost Australian markets but does occur with older properties or strong rental yields. Negative gearing is a significant feature of Australian tax policy and has been the subject of ongoing political debate, with some policy proposals to limit the deductibility of rental losses to future rental income only. Properties rented at below-market rates to relatives, or used privately for any period, may have their deductions reduced proportionally. Vacant land, holiday homes with restricted rental periods, and properties not genuinely available for rent may face additional restrictions on deductibility.
Net Rental Income = Gross Rent - Interest - Rates - Insurance - Repairs - Agent Fees - Depreciation; Tax Saving = Net Rental Loss × Marginal Tax Rate; After-Tax Cost = Net Rental Loss - Tax Saving
- 1Calculate gross annual rental income from the property — all rent received or accrued during the financial year.
- 2Add up all allowable deductions: mortgage interest, council rates, landlord insurance, property management fees, repairs and maintenance, body corporate fees, and accounting fees.
- 3Calculate the depreciation deduction — Division 43 building write-off (2.5% of construction cost) and Division 40 plant and equipment depreciation, ideally with a Quantity Surveyor's report.
- 4If total deductions exceed gross rental income, the difference is a net rental loss (negative gearing) which is declared in your tax return and offsets your other income.
- 5The tax saving is the rental loss multiplied by your marginal tax rate. At 37% marginal rate, a $10,000 loss saves $3,700 in tax.
- 6The actual after-tax holding cost is the out-of-pocket cash shortfall minus the tax saving. Consider whether the expected capital growth justifies this ongoing cost.
- 7When sold after 12 months, calculate the capital gain (sale price minus cost base including purchase costs and capital improvements). Apply the 50% CGT discount and include the net capital gain in assessable income.
The property needs capital growth to justify the after-tax holding cost.
Total deductions ($36,000) exceed income ($22,000) by $14,000. At 37% marginal rate, $5,180 is saved in tax. The investor's real cash shortfall is $8,820/year. If the property grows by 5% ($20,000+/year), the investment is profitable after tax.
Higher marginal rate makes negative gearing more tax-effective.
At the top marginal rate (including 2% Medicare Levy), the tax saving on a $19,000 loss is $8,930. The investor's out-of-pocket after-tax cost is $10,070, with the tax system subsidising nearly 47% of the loss.
CGT discount requires the asset to be held more than 12 months.
Cost base is $650,000 (purchase + costs + improvements). Capital gain = $820,000 - $650,000 = $170,000. After 50% CGT discount, $85,000 is added to taxable income. At 37%, CGT = $31,450.
Private use days proportionally reduce deductible losses.
Of 240 total days (180 rental + 60 private), 75% are income-producing. Only 75% of the $12,000 loss = $9,000 is deductible. The remaining $3,000 is disallowed due to private use.

What is negative gearing?
Negative gearing occurs when the interest and expenses of an investment property exceed the rental income. The resulting loss is deductible against other income (such as salary), reducing your taxable income and tax bill. The strategy relies on capital growth to generate profit when the property is eventually sold. This is particularly important in the context of negative gearing calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise negative gearing calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Is negative gearing legal?
Yes. Negative gearing is a legal feature of Australian tax law under section 8-1 of the Income Tax Assessment Act 1997, which allows deductions for losses incurred in earning assessable income. The ATO administers specific rules about what expenses are deductible and when. This is particularly important in the context of negative gearing calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise negative gearing calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is the 50% CGT discount?
Individuals and trusts who hold a capital gains asset for more than 12 months are eligible for a 50% discount on the capital gain when the asset is sold. Only half the net capital gain (after applying any capital losses) is included in assessable income. Companies and super funds have different discount rates.
Can I deduct interest on a vacant property?
Interest is deductible if the property is genuinely available for rent — for example, between tenancies or during renovation for rental purposes. However, if the property is not genuinely available (e.g., listed at an above-market rent to deter tenants, or renovated for eventual private use), the ATO may deny deductions.
Can I negatively gear shares?
Yes. Negative gearing applies to any income-producing asset, including shares. If you borrow to invest in shares and the interest and other expenses exceed dividends received, the loss can be offset against other income. The 50% CGT discount also applies to shares held more than 12 months. This is particularly important in the context of negative gearing calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise negative gearing calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What depreciation can I claim?
Two types of depreciation apply: Division 43 (building allowance) at 2.5% per year on the construction cost of buildings built after 15 September 1987, and Division 40 (plant and equipment) for items like appliances, carpets, and hot water systems. A Quantity Surveyor's depreciation schedule maximises these deductions. This is particularly important in the context of negative gearing calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise negative gearing calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What happens if I positively gear?
If rental income exceeds expenses, the net rental profit is added to your taxable income and taxed at your marginal rate. Positively geared properties generate ongoing taxable income but do not reduce your tax bill. They are most common with high-yielding regional or rural properties. This is particularly important in the context of negative gearing calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise negative gearing calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Could negative gearing be abolished?
Negative gearing reform has been debated in Australia for decades. Various proposals have suggested limiting deductions to rental income only (quarantining losses), or grandfathering existing arrangements. As of 2024, negative gearing remains available on all income-producing investments. Any changes would likely be prospective only. This is particularly important in the context of negative gearing calculator calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise negative gearing calculator computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Pro Tip
Before purchasing, model three scenarios: optimistic growth (7% per year), moderate growth (4%), and pessimistic (1%). At your marginal tax rate, calculate the after-tax holding cost and break-even capital growth needed. Many investors overestimate growth and underestimate holding costs.
Did you know?
Australia has one of the highest rates of property investor participation in the world. In 2021-22, over 2.2 million Australians declared rental income or losses in their tax returns, with the majority negatively geared. The total rental losses claimed exceeded $6 billion.
