Proven Tips to Maximise Tax Deductions on Investment Loans

Investment property tax rules changed significantly in the May 2026 Federal Budget, and the impact depends entirely on when you purchased.

If you bought before Budget night on 12 May 2026, you retain the existing arrangements. If you purchased an established property after that date, negative gearing and capital gains tax treatment shifts from 1 July 2027. Moorebank investors holding properties near Liverpool or the Georges River corridor need to understand what still qualifies as a deduction and how the new rules affect rental income calculations.

What Changed for Negative Gearing From July 2027

Negative gearing previously allowed you to offset rental losses against your total taxable income, including wages. From 1 July 2027, losses on established residential properties purchased after 12 May 2026 can only be offset against rental income or capital gains from residential property. You can carry forward unused losses to offset future residential property income, but you cannot use them to reduce your salary and wage tax liability in the same financial year.

Consider a buyer who purchased an established villa in Moorebank's residential precinct in June 2026 with an interest-only loan. Annual interest costs $28,000, with rental income at $24,000 after allowing for vacancy periods. Under the old rules, that $4,000 shortfall reduced their taxable income from all sources. Under the new arrangements applying from July 2027, that loss can only offset other residential rental income or be carried forward. If this investor holds one property and no other rental income, the deduction provides no immediate tax benefit.

New builds purchased after Budget night retain the option to use either the old 50% capital gains discount or the new indexed cost base method, whichever delivers the lower tax outcome. This creates an incentive for investors considering new apartments or townhouses in surrounding growth areas like Edmondson Park or Prestons, where construction activity remains strong.

Interest Costs Remain Fully Deductible

Loan interest on funds borrowed to purchase or improve an investment property remains a claimable expense regardless of when you bought. This applies whether you hold a variable rate loan, a fixed rate product, or a split arrangement. The interest component of repayments on principal and interest loans, or the full repayment on an interest-only loan, qualifies as a deduction.

In our experience, investors in Moorebank often hold interest-only loans for the first five years to maximise cash flow, then switch to principal and interest repayments once rental income increases or other financial priorities shift. The entire interest portion remains deductible throughout both phases, provided the loan purpose relates directly to the income-producing property.

If you refinance an investment loan to access a lower rate or release equity for another purchase, only the interest on the portion used for investment purposes remains deductible. Mixing investment and personal borrowing in the same loan structure creates complications at tax time, which is why separating loan accounts from the outset makes record-keeping and compliance more straightforward.

Depreciation and Capital Works Deductions Still Apply

Depreciation on fixtures, fittings, and structural elements continues to provide significant deductions for property investors. Plant and equipment items like ovens, air conditioners, and carpet depreciate over their effective life, typically between five and fifteen years depending on the asset. Capital works deductions apply to the building structure itself at 2.5% per year over 40 years for properties built after 1987.

A two-bedroom unit in one of Moorebank's older walk-up complexes near Newbridge Road may offer limited plant and equipment depreciation if previous owners have already claimed those items. A newer townhouse in the residential estates closer to the M5 corridor will typically generate higher depreciation deductions in the early years. Obtaining a quantity surveyor's depreciation schedule ensures you claim the full entitlement without overstepping ATO guidelines.

Investors sometimes overlook renovation costs as claimable capital works. Replacing a kitchen, adding a bathroom, or extending a living area can be depreciated over the applicable period if the work constitutes a capital improvement rather than a repair. Repairs and maintenance performed to restore an item to its original condition are immediately deductible in the year the expense occurs, while improvements are depreciated over time.

Rental Property Running Costs You Can Claim

Ongoing expenses directly related to earning rental income are deductible in the financial year they occur. Council rates, water charges, strata levies, landlord insurance, property management fees, and advertising costs for tenants all qualify. Repairs to fix wear and tear, such as replacing a broken tap or repainting scuffed walls between tenancies, are immediately deductible.

Moorebank's mix of standalone homes and medium-density strata units means some investors pay body corporate fees while others manage individual property expenses. Strata levies covering building insurance, common area maintenance, and sinking fund contributions are fully deductible. If your strata plan undertakes major works such as roof replacement or facade repairs funded through a special levy, that portion relating to your unit is also claimable, though the treatment depends on whether the expense is a repair or a capital improvement.

Loan establishment fees, valuation costs, and legal fees incurred when purchasing or refinancing can be claimed over five years or the loan term, whichever is shorter. Lenders Mortgage Insurance paid upfront is also deductible over the same period. If you refinance within that five-year window, the remaining unclaimed portion can be deducted in the year you discharge the original loan.

Capital Gains Tax From July 2027

The 50% capital gains discount that applied to assets held longer than 12 months is being replaced with a cost base indexed to inflation, plus a minimum 30% tax on gains. This affects established properties purchased after Budget night, with the changes taking effect from 1 July 2027. Gains that accrued before that date are not retrospectively affected.

If you sell an investment property you purchased before 13 May 2026, the existing 50% discount applies to any gain realised after 1 July 2027, provided you held the property for at least 12 months. The indexed cost base method applies only to properties acquired after Budget night. For those new builds, investors can choose whichever calculation delivers the lower taxable gain.

The indexed cost base reduces the taxable gain by adjusting your original purchase price for inflation. If you bought at $650,000 and inflation over your holding period totals 15%, your indexed cost base becomes $747,500. Selling at $850,000 results in a $102,500 gain rather than $200,000. The minimum 30% tax then applies to that indexed gain, meaning you pay at least $30,750 in capital gains tax regardless of your marginal rate. This floor ensures high-income earners do not avoid tax entirely through indexation.

How Loan Structure Affects Deductibility

The way you structure your investment loan from the outset determines how much you can claim each year. Borrowing the maximum amount for the investment property and keeping personal funds separate ensures every dollar of interest qualifies as a deduction. Using savings to reduce the investment loan but increasing your owner-occupied mortgage reduces your deductible interest and increases non-deductible debt.

Some Moorebank investors use equity from their family home to fund a deposit on a rental property. If the loan account used to access that equity is clearly tied to the investment purchase, the interest remains deductible even though the security is your home. Mixing purposes in a single loan account, such as drawing on the same facility for a holiday or car purchase, dilutes the deduction and creates record-keeping complexity. Keeping loan splits or separate accounts for each purpose avoids disputes with the ATO.

Interest-only loans maximise deductions in the short term because you are not using cash flow to reduce the principal balance. Principal and interest repayments reduce the loan balance over time, which lowers the deductible interest component each year. Many investors hold interest-only terms while building a portfolio, then transition to principal and interest once they stop acquiring new properties or approach retirement.

Claiming Travel and Home Office Expenses

Travel to inspect your investment property, meet with tenants or property managers, or oversee repairs is deductible at the ATO's prescribed rate per kilometre or based on actual vehicle expenses if you keep detailed records. Travel between your home and the rental property purely to collect rent is not deductible if rent could reasonably be collected by other means, such as direct deposit.

If you manage the property yourself and use a room at home exclusively for investment property administration, you may be able to claim a portion of home office expenses. The space must be set aside solely for that purpose, not a dual-use area like a kitchen table. Given the administrative burden and modest deduction relative to the work involved, most Moorebank investors engage a property manager and claim the management fee instead, which typically runs between 5% and 8% of gross rental income depending on the service level.

Record Keeping and Substantiation Requirements

The ATO requires written evidence for every deduction you claim. Bank statements, invoices, receipts, and loan statements must be retained for five years after you lodge your tax return. For rental income, keep records of lease agreements, rent received, bond lodgement details, and any periods where the property was vacant or used for personal purposes.

If you use the property yourself at any point during the financial year, you must apportion expenses based on the time it was genuinely available for rent versus personal use. Claiming full deductions while using the property for holidays or allowing family members to stay rent-free will attract ATO scrutiny. Moorebank's proximity to Liverpool CBD and major transport routes makes short-term personal use tempting, but accurate record-keeping is non-negotiable.

Digital records are acceptable provided they are clear and complete. Scanning receipts and maintaining a cloud-based folder for each property simplifies tax preparation and ensures nothing is lost if a physical document is damaged. Many accounting software platforms integrate with bank feeds to categorise transactions automatically, though you should review and verify each entry rather than relying entirely on automation.
