Simple hacks to maximise negative gearing deductions

Negative gearing allows you to offset rental property losses against your salary or other income, reducing your overall tax burden.

The tax treatment of your investment loan directly affects your cash flow and long-term returns. For Mount Eliza residents looking at rental property, understanding which expenses are claimable and how loan structure influences deductions can shift a marginal proposition into a solid wealth-building strategy.

How Negative Gearing Works for Investment Loans

Your rental property is negatively geared when your interest payments and holding costs exceed your rental income. The resulting loss reduces your taxable income for that financial year. Interest on your investment loan is deductible to the extent the property is rented or genuinely available for rent. Council rates, insurance, property management fees, repairs and depreciation are also claimable during that period.

Consider a Mount Eliza investor who purchases a two-bedroom unit with an interest-only loan. Rental income covers roughly 70 per cent of the annual interest bill, before other expenses. The shortfall, plus rates, body corporate fees and insurance, creates a loss that offsets income from employment. Over time, rental growth and debt reduction improve cash flow, while capital growth builds equity that can be leveraged for portfolio expansion.

Interest-Only Versus Principal and Interest Loans

Interest-only repayments maximise your annual interest deduction because you are not reducing the loan balance during the interest-only period. This structure suits investors who want to preserve cash flow and redirect surplus funds into other assets or additional property purchases. Most lenders offer interest-only periods of up to five years on investment loans, after which the loan reverts to principal and interest unless you renegotiate.

Principal and interest repayments reduce your loan balance each month, which lowers your interest expense and therefore your deduction over time. This structure builds equity faster and reduces your overall interest cost, but it also increases your monthly repayment and can turn a negatively geared property into a positively geared one sooner. The choice depends on whether you prioritise immediate tax relief and liquidity or long-term debt reduction.

Claimable Expenses Beyond Interest

Loan establishment fees, ongoing account-keeping fees and discharge fees related to your investment loan are deductible in the year they are incurred or can be amortised over the life of the loan, depending on the amount. If you refinance, the remaining balance of any deferred establishment costs from the original loan becomes immediately deductible.

Stamp duty on the property purchase and legal fees related to the acquisition are not immediately deductible but form part of your cost base for capital gains tax purposes when you sell. Body corporate fees, property management fees, landlord insurance, water and council rates are deductible in the year they are paid. Repairs are immediately deductible, while improvements that increase the property's value must be depreciated over time. Lenders Mortgage Insurance premiums paid at settlement are deductible, either in full in the first year or spread over five years.

Fixed Rate or Variable Rate for Negative Gearing

A variable rate loan gives you flexibility to make extra repayments without penalty and to access redraw or offset facilities. For negatively geared investors, the offset account does not reduce your deductible interest if structured correctly, because the loan balance itself remains unchanged. Variable rates move with the Reserve Bank's cash rate, which means your interest deduction will fluctuate over time.

A fixed rate locks in your interest cost for a set period, typically one to five years. This provides certainty around your deduction and repayment amount, which can help with budgeting and tax planning. However, fixed loans typically restrict extra repayments and may carry break costs if you refinance or sell before the fixed term ends. Some Mount Eliza investors split their loan between fixed and variable to balance certainty and flexibility.

Legislative Changes from Mid-2026 Onward

Properties acquired after 12 May 2026, other than eligible new builds, will be subject to new negative gearing rules from the start of the 2027-28 income year. Losses on those properties can only be offset against income from other residential property, including capital gains on residential property. Losses cannot be claimed against salary, business income or other investment income. Excess losses can be carried forward to future years and applied against residential property income at that time.

Properties held or under contract before 12 May 2026 retain full negative gearing treatment indefinitely. Eligible new builds, defined as dwellings constructed on vacant land or where the rebuild increases the number of dwellings on the site, also retain full negative gearing regardless of purchase date. A knock-down rebuild that replaces one dwelling with one dwelling does not qualify. For investors purchasing in Mount Eliza now, established properties such as units near Canadian Bay or renovated homes in Mount Eliza village will be subject to the new rules if acquired after the cut-off date.

Structuring Your Loan to Preserve Deductibility

Borrowing for both investment and private purposes on the same loan can reduce the deductible portion of your interest. If you use part of your loan to fund renovations on your own home or to buy a car, that portion of the interest is not claimable. The solution is to split your borrowing into separate loan accounts at the outset, one for the investment property and one for private expenses, even if both are secured against the same property.

If you later draw on equity in your investment property to fund another investment, the interest on that additional borrowing remains deductible provided the funds are used for income-producing purposes. Releasing equity to purchase a second rental property, for example, means the interest on both loans is claimable. Releasing equity to renovate your home means the interest on that portion is not. Record-keeping is important because lenders do not track the purpose of funds for tax purposes.

Using Rental Income to Improve Serviceability

Lenders assess your ability to service an investment loan by including a portion of the expected rental income, typically 80 per cent to allow for vacancy and management costs. The remaining 20 per cent is treated as a buffer. Your loan application will include a rental assessment or market appraisal to justify the income figure. Mount Eliza properties close to the village, schools or beach access tend to attract stable tenant demand, which supports rental income assumptions.

If you already own investment property, existing rental income can improve your borrowing capacity for a second purchase. Lenders will also consider whether your current investment loan is positively or negatively geared. A large ongoing loss reduces your surplus income and may limit how much you can borrow, even if the tax benefit is valuable. Some lenders apply a debt-to-income cap, particularly for investors, which limits total borrowing to a multiple of your gross income regardless of rental income.

Offset Accounts and Negative Gearing

An offset account linked to your investment loan reduces the interest you pay but does not reduce the loan balance for tax purposes. If your loan balance is $500,000 and you hold $50,000 in offset, you pay interest on $450,000 but you still claim interest deductions based on the full $500,000 loan. This structure only works if the loan is genuinely for investment purposes and the offset is not funded by mixing investment and private cash flows in ways that blur the purpose of the borrowing.

Some investors prefer to keep surplus cash in an offset account linked to their owner-occupied home loan rather than their investment loan. This approach reduces non-deductible interest on the home loan while preserving the full deductible interest on the investment loan. The right structure depends on your loan balances, interest rates and cash flow needs.
