Investment Property Tax Deductions Australia: The Complete List (2026)

Tax deductions are the mechanism that makes Australian property investment more financially efficient than the pre-tax numbers suggest. The ATO allows investors to deduct a wide range of costs against their rental income — and where those deductions exceed rental income, the resulting loss reduces taxable income from salary, generating a real tax refund.

Most investors claim the obvious deductions: loan interest, property management fees, rates. Fewer claim everything they are entitled to. This guide covers every deduction available to Australian investment property owners in 2026, what each is worth, and what most investors miss.

All investment property deductions fall into one of two categories: immediately deductible expenses, and capital expenses deductible over time.

Immediately deductible expenses are claimed in full in the financial year they are incurred. They directly reduce your taxable rental income (and through negative gearing, your total taxable income) in the year of the expense.

Capital expenses deductible over time cannot be claimed immediately. They are either depreciated over the useful life of the asset (plant and equipment), or written off over 40 years under the capital works provisions (Division 43). These generate deductions across multiple future years, not all at once.

Understanding which category an expense falls into is essential — claiming a capital expense as an immediate deduction is an error the ATO will correct, and the reverse (failing to claim depreciation) is money left on the table every year.

Loan interest — the largest deduction for most investors. The interest component of repayments on money borrowed to purchase or improve the investment property is fully deductible. The principal component is not. On an interest-only loan of $600,000 at 6.8%, the annual deduction is $40,800. On a P&I loan, only the interest portion is deductible — this reduces over time as the balance falls.

Property management fees — the fee charged by the property manager, typically 7 to 10% of gross rent plus GST. Letting fees (charged when a new tenant is placed) are also immediately deductible. On $30,000 annual gross rent at 8.5%, this is approximately $2,550 per year.

Council rates — fully deductible in the year paid. Typically $1,500 to $2,500 per year for a suburban investment property.

Water rates — the fixed service charge and any usage charges paid by the landlord are deductible. Tenant-paid water usage is not (but is also not your expense). Typically $800 to $1,200 per year.

Land tax — deductible in the year it is assessed. Land tax applies in most states once total landholdings exceed the state-specific threshold. It is one of the most commonly missed deductions because it arrives as a separate government notice rather than through the property manager.

Landlord insurance — premiums for landlord insurance (covering loss of rent, damage by tenants, public liability) are fully deductible. Typically $1,200 to $2,000 per year.

Body corporate fees / strata levies — the regular administrative levy is immediately deductible. Special levies for capital works (major building repairs) are a capital expense, not immediately deductible — they go to the capital works fund or must be depreciated.

Repairs and maintenance — costs to restore the property to its original working condition are immediately deductible. This includes fixing a broken hot water system, repairing a leaking roof, painting to maintain condition, and replacing like-for-like fixtures. The key distinction: repairs restore; improvements upgrade. Repairs are deductible; improvements are capital (and depreciated). A new kitchen where the old one was functional is an improvement. Fixing the existing kitchen is a repair.

Advertising for tenants — the cost of advertising a vacancy (online listings, signage) is immediately deductible.

Pest control and cleaning — cleaning and pest inspection costs incurred while the property is rented or genuinely available for rent are deductible.

Gardening and lawn maintenance — if included in the landlord's obligations under the lease, gardening costs are deductible.

Lock changes — when a tenant vacates and locks are changed for security, this is a deductible repair and maintenance cost.

Tax agent and accounting fees — fees paid to a registered tax agent for preparing your investment property tax return are immediately deductible. Typically $300 to $600 per year for a rental property schedule.

Quantity surveyor fees — the cost of commissioning a depreciation schedule is immediately deductible. On a property built after 1987, this pays for itself within the first year of additional depreciation claims.

Interest on loans for property improvements — if you borrow to fund capital improvements to the property, the interest on that borrowing is deductible while the property is rented, even though the improvement itself is depreciated rather than immediately deductible.

Bank fees on investment loan accounts — monthly account keeping fees and other bank charges on your investment loan account are deductible.

Stationery, postage, phone costs — the portion of phone and internet costs attributable to managing the investment property (calling the property manager, reviewing statements) is deductible. Keep a reasonable record — the ATO does not expect a detailed log for minor incidental costs.

Depreciation generates deductions without any cash outflow in the year of the claim. The building and its fixtures decline in value over time — the ATO allows you to claim this decline as a tax deduction, reducing your assessable income every year for decades.

Division 43 — Capital Works Deduction (2.5% per year)

The building structure itself — walls, floors, roofing, fixed stairs, wet areas — depreciates at 2.5% of its original construction cost per year for 40 years from the date of construction. If the property was built in 2005 at a construction cost of $280,000, you can claim $7,000 per year in Division 43 depreciation. This applies to any residential property built after 15 September 1987, and to commercial property built after 1982.

The construction cost is not the purchase price — it is the cost of building the structure alone, excluding land. A quantity surveyor estimates this for older properties where the original building contract is not available. They use comparable construction cost data and site inspection to produce a defensible estimate for the ATO.

Division 40 — Plant and Equipment Depreciation

Removable assets — hot water systems, ovens, dishwashers, carpet, blinds, air conditioning units, exhaust fans — depreciate over their effective life at either the diminishing value or prime cost method. Each asset class has an ATO-specified effective life. A hot water system, for example, depreciates over 12 years. New carpet over 8 years. Air conditioning over 10 years.

The 2017 rule change for established properties: For residential investment properties purchased from 9 May 2017 onward, Division 40 depreciation on second-hand plant and equipment is restricted for individual investors. You can only claim Division 40 on assets you purchase new and install yourself (such as a new hot water system installed after purchase), or on assets in a property purchased new directly from the developer. Plant and equipment that was already in an established property when you bought it cannot be depreciated by individual investors under current rules.

This restriction does not apply inside an SMSF — funds can depreciate second-hand plant and equipment on properties purchased after 2017. Another structural advantage of the SMSF.

Borrowing costs — loan establishment fees, mortgage registration fees, title search fees, and mortgage broker fees paid when taking out the investment loan are deductible over the lesser of 5 years or the loan term. Not all at once.

Land tax. Arrives as a separate government notice, not through the property manager. Many investors file their tax return without including it because it is not on their rental summary statement. Check your state revenue office records — if you hold property above the threshold, you owe land tax and it is deductible.

Depreciation on capital improvements made during ownership. If you renovated the property during ownership — new kitchen, new bathroom, extension — the cost of those works creates a new Division 43 depreciation stream at 2.5% per year from the date of completion. A $40,000 kitchen renovation generates $1,000 per year in additional Division 43 deductions for 40 years. Most investors do not add post-purchase capital works to their depreciation schedule. Update the schedule with your quantity surveyor when significant capital works are completed.

Interest on borrowed deposit funds. If you drew equity from another property to fund the deposit on this investment property, the interest on the equity release loan is deductible against the investment property income. The loan purpose — investment — determines deductibility, not which property the loan is secured against.

Lease preparation costs. Legal costs for preparing the initial lease agreement are deductible over the lease term, not immediately — but they are deductible.

Costs incurred before the property is first rented. Where costs are incurred after purchase but before the property is first available for rent — advertising, initial cleaning, key cutting — these are deductible from the date the property is first genuinely available for rent. You do not have to wait until rent is actually received.

Quantity surveyor fee itself. Many investors pay a quantity surveyor but then do not claim the fee. It is immediately deductible in the year paid.

PAYG Withholding Variation. Not a deduction, but directly related: if your total deductions significantly exceed your rental income (creating a tax loss), you can apply to have your employer reduce the tax withheld from your salary throughout the year rather than waiting for the annual refund. This means you receive the tax benefit monthly instead of as a lump sum in July/August. Apply using the ATO withholding variation form.

Knowing what cannot be claimed is as important as knowing what can. The following are common errors:

Principal repayments — never deductible. Only the interest component of loan repayments reduces your taxable income.

Capital improvements — a new kitchen that upgrades (not merely repairs) the property, an extension, a pool, structural changes — these are not immediately deductible. They must be depreciated over time (Division 43 at 2.5% per year for building works) or added to the cost base for CGT purposes.

Purchase costs — stamp duty, conveyancing fees, building and pest inspection at purchase, buyer agent fees — none of these are immediately deductible. They form part of the cost base for CGT when you eventually sell.

Expenses during vacancy when not genuinely available for rent — if the property is vacant because you are deciding whether to sell, renovating, or holding it for personal use, expenses during that period are not deductible. The property must be genuinely available for rent or tenanted for expenses to be deductible.

Private use expenses — if you or your family use a holiday property for any period personally, only the proportion of time it is rented or genuinely available for rent is deductible. Mixed-use properties require careful apportionment.

Expenses that have already been reimbursed — insurance claims, amounts recovered from tenants for damage — reduce your deductible expense to the net amount you actually bore.

Commission a depreciation schedule from a registered quantity surveyor before lodging your first tax return after purchase. For properties built after 1987, this is the single highest-value action most investors have not taken. The schedule costs $600 to $800 and generates thousands in deductions annually.

Claim land tax — check your state revenue office records and include the assessment notice in your tax documents.

Separate your investment loan account from any personal accounts. This makes interest calculation clean, prevents mixed-purpose contamination, and simplifies the tax return.

Keep all receipts for repairs and maintenance — the distinction between a deductible repair and a non-deductible improvement is one the ATO audits. Good records protect you.

Update your depreciation schedule when you complete capital works. Ask your quantity surveyor to add the new works to the existing schedule.

Apply for a PAYG Withholding Variation if your annual tax refund from negative gearing is significant — get it monthly rather than waiting for tax return lodgement.

Use a specialist property investment accountant — not every general accountant is across the full range of investment property deductions, the Division 43/40 distinction, or the 2026 rule changes. An accountant who specialises in property investors typically identifies deductions that a general practitioner misses.

The 2026 budget did not change the list of available deductions for properties already held. All immediately deductible expenses remain immediately deductible. Division 43 and Division 40 depreciation are unchanged. The PAYG Withholding Variation process is unchanged.

What changed for new residential investment property purchases after the cutoff date: the tax loss generated by the deductions cannot be immediately applied against salary income. The deductions still arise — they are quarantined and applied against future rental income or capital gains from the same property rather than against current year salary. The deductions are not lost; their timing is deferred.

For investors with existing properties purchased before the cutoff, the 2026 budget changes nothing about your deductions or how they are applied. For investors considering new purchases, the deferral of the negative gearing benefit increases the annual cash cost of holding the property and should be factored into your feasibility modelling.
