Understanding Negative Gearing in Australia
Negative gearing is a popular investment strategy used by many Australian property investors. When you own an investment property where the annual expenses exceed the rental income, you're negatively geared. This creates a tax-deductible loss that can be offset against your other income, potentially reducing your overall tax bill. From 1 July 2027 this offset against wages is being restricted for established properties bought after 12 May 2026 (the loss can then only offset property income), though the current rules still apply for the 2026-27 financial year. See our guide to the 2026-27 changes for the detail.
Our negative gearing calculator helps you understand the true cash flow of your investment property. By entering details about your property purchase price, loan structure, rental income, and expenses, you can see exactly how much you'll need to contribute each year and what tax benefits you might receive.
How Negative Gearing Works: A Real Example
Let's look at a practical example using 2026 figures. Sarah purchases a $650,000 investment property in Brisbane with a 20% deposit ($130,000). She takes out a $520,000 interest-only loan at 6.5% interest. Here's her annual position:
Annual income
- Rental income (52 × $550)
- $28,600
- Less vacancy (5%)
- −$1,430
- Net rental income
- $27,170
Annual expenses
- Loan interest (6.5%)
- $33,800
- Council rates
- $2,500
- Insurance
- $1,200
- Property management (7.5%)
- $2,038
- Maintenance
- $2,000
- Depreciation
- $10,000
- Total expenses
- $51,538
Taxable loss: −$24,368. At 37% marginal rate, Sarah receives $9,016 tax refund, reducing her actual out-of-pocket cost to $15,352 per year ($1,279/month).
2026 Australian Tax Brackets and Negative Gearing Benefits
Your marginal tax rate determines how much benefit you receive from negative gearing. Under the 2026-27 tax year brackets (including Medicare levy), here's how different income levels benefit from a $20,000 property loss:
| Taxable income | Tax rate | Tax saving |
|---|---|---|
| $45,001-$135,000 | 32% | $6,400 |
| $135,001-$190,000 | 39% | $7,800 |
| $190,000+ | 47% | $9,400 |
Higher income earners receive more benefit from negative gearing due to Australia's progressive tax system. This is why negative gearing is particularly attractive for professionals and executives in the higher tax brackets. Every dollar of deductible loss returns more cents in the dollar through tax savings.
The Role of Depreciation in Maximizing Returns
Depreciation is often the difference between moderate and excellent negative gearing outcomes. It's a non-cash deduction, meaning you claim it on tax without actually spending the money that year. There are two types:
Building Depreciation (Capital Works): Structures built after 1985 can be depreciated at 2.5% per year for 40 years. A $400,000 building value provides $10,000 annual deduction. This applies to apartments, townhouses, and houses built in the last few decades.
Plant and Equipment Depreciation: Fixtures like air conditioners, carpets, blinds, hot water systems, and appliances depreciate faster—typically over 5-15 years. A comprehensive depreciation schedule can identify $2,000-$5,000 in annual plant deductions for established properties, or up to $10,000+ for new properties.
For a property purchased in 2020 for $600,000, a quantity surveyor's report might uncover $12,000 in depreciation deductions annually for the first few years. At a 37% tax rate, that's $4,440 in tax savings from a non-cash expense. Over 10 years, this could add up to $40,000+ in extra tax refunds.
Long-Term Projections and Capital Growth
The calculator provides 10-year projections assuming 3% annual growth in both rents and expenses. This helps you understand the trajectory of your investment. Many properties start negatively geared but become cash flow positive over time as rents increase while the loan interest (on interest-only loans) stays constant.
Remember, negative gearing works best when combined with strong capital growth. While you may be contributing $15,000 per year after tax benefits, if the property value increases by 5% annually ($32,500 in year one on a $650,000 property), your total return is highly positive. Over 10 years with 5% compound growth, that $650,000 property would be worth over $1 million—a gain of $400,000+ that far outweighs the $150,000 in negative cashflow contributions.
Consider rentvesting: Many investors combine negative gearing with a rentvesting strategy, buying investment property in affordable high-yield areas while renting where they want to live. This maximizes tax benefits from negative gearing while maintaining lifestyle flexibility. Our rentvesting calculator helps you compare the total cashflow of this approach.
State-Specific Considerations: Land Tax
Our calculator includes automatic land tax estimation based on your state. Land tax rules vary significantly across Australia—some states have low thresholds (NSW investment property land tax starts around $755,000 land value), while others have higher thresholds or no land tax at all. The calculator estimates land value as approximately 40% of your property price and applies state-specific rates.
In high-value areas like Sydney's inner suburbs, land tax can add $2,000-$10,000+ to annual expenses. In states like Tasmania or Northern Territory with more favorable land tax regimes, this cost may be minimal or zero. Understanding your likely land tax position is crucial for accurate cashflow forecasting.
Interest Rates and Stress Testing Your Investment
With the calculator's default 6.5% interest rate reflecting current (2026) investment loan rates, it's important to consider interest rate risk. If rates rise to 7.5% on a $500,000 loan, that's an extra $5,000 per year in interest costs. At 37% tax rate, the tax benefit covers $1,850 of this, but you're still $3,150 worse off annually.
Always stress test your investment at 2-3% higher interest rates than current levels. If you can't afford the property at 8-9% interest rates, you may be overextended. The best negative gearing strategies have sufficient cashflow buffers to handle rate increases without financial stress.
