Negative Gearing: How It Works & What It Costs

Negative gearing occurs when the costs of holding an investment property exceed the rental income it generates, creating a loss that reduces your taxable income.

For property investors in Narellan, where rental yields typically sit between 3.5% and 4.5% depending on property type and location within the suburb, negative gearing is a common outcome in the first years of ownership. The tax benefit offsets part of your holding costs while you wait for capital growth to build wealth over time.

How Negative Gearing Reduces Your Tax Bill

You can claim the shortfall between your investment property expenses and rental income as a tax deduction against your total assessable income. If your property costs $32,000 annually to hold but generates $28,000 in rent, the $4,000 shortfall reduces your taxable income by that amount. At a marginal tax rate of 37%, this saves you $1,480 in tax.

Your deductible expenses include loan interest, property management fees, council rates, insurance, repairs, and depreciation on the building and fixtures. Loan interest typically represents the largest expense. On an investment loan of $600,000 at current variable rates, annual interest might reach $24,000 or more depending on the rate your lender offers.

Consider an investor who purchases a townhouse in Narellan Vale using interest-only repayments. The property rents for $550 per week, generating $28,600 annually. Loan interest costs $25,200, property management fees add $1,716, insurance costs $1,200, council rates are $1,800, and depreciation adds another $4,500 in claimable expenses. Total expenses reach $34,416, creating a $5,816 loss. At a 39% marginal rate including Medicare Levy, this saves $2,268 in tax, reducing the out-of-pocket cost to $3,548 annually.

When Negative Gearing Makes Sense for Your Situation

Negative gearing works when you have sufficient taxable income to absorb the loss and enough cash flow to cover the shortfall between rent and expenses. The strategy assumes capital growth will eventually exceed the cumulative holding costs.

Investors typically need a taxable income above $90,000 to benefit meaningfully from negative gearing. Below this threshold, the tax saving may not justify the ongoing cash contribution required to hold the property. If you earn $70,000 and face a 32.5% marginal rate, a $5,000 loss saves $1,625 in tax but still requires $3,375 from your own funds each year.

Your deposit size also influences whether negative gearing suits your circumstances. A 20% deposit on a Narellan investment property avoids Lenders Mortgage Insurance and reduces your loan amount, lowering interest costs and narrowing the gap between income and expenses. A smaller deposit increases borrowing costs and amplifies the negative cash flow, requiring higher income to sustain the holding period.

Interest-Only Loans and Their Effect on Cash Flow

Interest-only repayments maximise your tax deductions because the entire repayment is deductible, unlike principal and interest loans where only the interest portion reduces your taxable income. Most lenders offer interest-only periods of up to five years on investment loan products, with some extending to ten years for investors with strong equity positions.

Switching from principal and interest to interest-only on a $600,000 loan might reduce monthly repayments by $1,500 or more, improving cash flow during the negative gearing phase. When the interest-only period ends, repayments revert to principal and interest at the remaining loan term, which increases your monthly cost but also begins reducing the debt.

Some investors refinance to a new interest-only term before the initial period expires, particularly if the property remains negatively geared and they want to preserve cash flow. This approach extends the holding period without increasing out-of-pocket contributions, though it also delays debt reduction. An investment loan refinance may also secure a lower rate or better loan features if your equity position has improved.

How Rental Vacancies Change Your Deductions

A vacant property still allows you to claim expenses if the property remains genuinely available for rent. You cannot claim a deduction during periods when the property is used for private purposes or withdrawn from the rental market.

In Narellan, vacancy rates for houses and townhouses generally remain low due to consistent demand from families relocating to the Macarthur region. However, a four-week vacancy between tenants still costs you a month of rental income while expenses continue. If your property typically rents for $550 per week, a vacancy reduces annual income by $2,200, widening the negative gearing loss and increasing your tax deduction.

You can claim advertising costs, property management fees during the vacancy, and ongoing holding costs like council rates and insurance. Loan interest remains deductible throughout the vacancy period as long as the property is held for income-producing purposes.

Capital Growth and the Exit from Negative Gearing

Negative gearing is a temporary phase in most investment strategies. As rents increase over time and your loan balance remains static or reduces, rental income eventually exceeds expenses and the property becomes positively geared.

If your Narellan property increases in value by 5% annually, a $700,000 townhouse reaches $894,000 after five years. If rents increase by 3% annually during the same period, weekly rent moves from $550 to $637, adding $4,524 to your annual income. Meanwhile, if you refinanced to a lower rate or your fixed term expired onto a lower variable rate, interest costs may have reduced. The combination of higher income and stable or lower expenses shifts the property into positive cash flow.

At this point, you pay tax on the net rental income instead of receiving a tax deduction, but the capital growth has built equity that can be leveraged for portfolio expansion or released to fund other goals. Whether you retain a negatively geared property until it turns positive depends on your income, cash reserves, and investment timeline.

Structuring Your Loan Application to Maximise Deductions

Lenders assess investment loan applications differently than owner-occupied home loans. Most lenders apply a rental income assessment of 70% to 80% of the expected rent, meaning they only count $385 to $440 per week even if market rent is $550. This serviceability buffer accounts for vacancies, management fees, and maintenance costs.

To maximise your borrowing capacity, separate any personal expenses from the investment loan. Mixing funds reduces the deductibility of interest and complicates your tax position. If you use equity from your owner-occupied home to fund the deposit on an investment property, structure the borrowing so the new loan is used solely for the investment. Interest on funds borrowed for investment purposes remains deductible, while interest on funds used for private purposes does not.

Some investors use an offset account linked to their owner-occupied loan rather than the investment loan. This approach keeps surplus cash working to reduce non-deductible interest on your home while the investment loan remains fully drawn and fully deductible. Your mortgage broker can structure the loans to preserve the tax benefits while improving overall interest costs across both properties.

Common Mistakes That Reduce Your Tax Benefits

Claiming ineligible expenses or failing to separate capital improvements from repairs reduces your deductions and creates compliance issues. Repairs and maintenance are immediately deductible, while capital improvements like renovations or extensions must be depreciated over time.

If you repaint the property in the same colour scheme, the cost is a repair and fully deductible in the year incurred. If you add a deck or renovate the kitchen, those costs are capital works and depreciated at 2.5% annually over 40 years. Understanding the distinction ensures you claim the maximum deduction without triggering an audit.

Another error is failing to claim depreciation on the building and fixtures. A quantity surveyor can prepare a depreciation schedule that identifies all claimable items, typically costing $600 to $800 but unlocking thousands in annual deductions. Properties built after 1985 qualify for building depreciation, while all properties can claim depreciation on fixtures like carpets, blinds, and appliances regardless of construction date.
