Landlord tax deductions in Australia: the checklist that actually matters

Most investors leave three to five thousand dollars of legitimate deductions on the table every year. The pattern is always the same. They claim the interest bill because their broker reminded them. They claim the strata levies because the body corporate prints a year-end statement. Then they miss the small things, miscategorise a renovation as a repair, or claim travel costs that the ATO disallowed back in 2017. None of this is exotic. It's just the checklist nobody walks through with them.

Here is the working list of deductions an Australian landlord can claim on a residential rental in 2026, the bits the ATO explicitly disallows, and a worked example showing how a typical loss-making position converts to a real tax refund.

The obvious ones (which most landlords get right)

Interest on the investment loan.The interest component of your loan repayments is deductible in the year you pay it. Principal isn't. If your bank statement shows a $4,200 monthly repayment of which $3,100 is interest, you claim $3,100. A loan that's been redrawn for personal purposes complicates this; the ATO apportions interest by purpose, not by account name, so a $50k redraw for a kitchen renovation on your own home taints the deductibility of that portion of the loan balance.

Council rates and water rates. Both are fully deductible when paid by the landlord. If the tenant pays water consumption charges direct to the utility, you only claim the fixed service charges that hit your name. Tenants almost never pay council rates.

Strata or body-corporate fees. The general administration fund and the sinking fund contributions are both deductible in the year you pay them. Special levies for capital works (a new roof on the block, a lift refurbishment) are not immediately deductible; they get added to the Division 43 capital-works pool and depreciate at 2.5% a year. Body-corporate statements rarely separate these clearly, which is one of the more common sources of audit-bait categorisation.

Land tax. Deductible in the state where the property sits, in the year you pay it. The threshold and rate depend on state and on whether your ownership structure triggers the trust surcharge or absentee-owner loading; the deduction itself is straightforward.

Property-management fees. The 6 to 8 per cent the agent takes off the rent, the leasing fee at the start of a new tenancy, the annual statement fee, the routine inspection charges, and the lease-renewal admin fee are all deductible. Bond-lodgement fees are too.

Advertising for tenants.Listing fees on the major portals, professional photography for the listing, sign boards, and copywriting all count. They're usually bundled into the agent's leasing fee but appear as separate line items on the statement.

Insurance. Landlord insurance, building insurance, and contents insurance (for any furnishings you provide) are all deductible in the year paid. If you pay an annual premium in June for cover running July to June, the full premium is deductible in the year of payment, not pro rated.

The line that costs investors thousands: repairs versus improvements

This is the single biggest source of over- and under-claiming in the rental-property space. The ATO line is sharper than most landlords realise.

A repair restores an item to its original condition without bettering it. Patching a hole in plaster. Replacing a broken tap with the same model. Fixing a leaking gutter section. Repainting a wall that was already painted. These are immediately deductible in the year you pay.

An improvementchanges the character of the asset or makes it better than the original state. Replacing the kitchen with a new one. Upgrading from carpet to floating floorboards. Adding a second bathroom. Replacing a tin roof with Colorbond. These are capital works under Division 43 and depreciate at 2.5 per cent a year over forty years, or in some cases they sit in the Division 40 plant-and-equipment pool with their own effective life. They don't hit your tax return as a current-year deduction; they slow-bleed across decades.

A useful test: would a competent tradesperson describe the work as "like for like" or as "upgrade"? Like-for-like is a repair. Upgrade is an improvement. The distinction matters because investors regularly claim a $14,000 kitchen replacement as a repair, get away with it for two years, and then lose the lot when the ATO data-matches the tradie's invoice. The depreciation schedule article works through what gets capitalised and how the schedule tracks it for the next forty years.

Two more wrinkles. Repairs to defects that existed when you bought the property (the previous owner's deferred maintenance) are notdeductible as repairs; they get capitalised even if they're plainly like-for-like work. And the first round of repairs after settlement is the most heavily scrutinised, because the ATO assumes any immediate-post-purchase work is likely fixing pre-existing defects rather than new wear and tear.

Depreciation: the deduction you don't pay cash for

Depreciation is the largest single deduction for most newer rental properties, and the only major one that doesn't require cash to leave your account. A quantity-surveyor schedule produces two streams: Division 43 (capital works, the building structure itself, 2.5 per cent a year for 40 years on the construction cost) and Division 40 (plant and equipment, the removable assets such as carpets, blinds, appliances, hot water systems, with each item on its own effective life).

Since 9 May 2017, Division 40 on existing assets is locked out for second-hand residential property. You can still claim Division 43 on the structure and Division 40 on anything you install yourself after settlement, but not on the carpets and appliances you inherited at the keys handover. Brand-new property keeps the full package. The depreciation article linked above runs the numbers end to end and shows why the $700 to $900 cost of the schedule almost always pays for itself in the first month it lands in your return.

The bits the ATO explicitly disallows

Travel to inspect your investment property. Since 1 July 2017, travel expenses to inspect or maintain residential rental property are not deductible for individual investors, regardless of distance. No flights, no mileage, no accommodation. The ATO closed this off because it was being used by interstate investors to deduct what looked a lot like holidays. Commercial property is different, and the rule doesn't apply if you're carrying on a property business at scale (a high bar, not a comfort for the typical one- or two-property investor).

Expenses for the period the property was your home. If you converted a former PPOR into a rental midway through the year, you can only claim from the date the property became genuinely available for rent. Council rates, interest, and insurance for the owner-occupier months are not deductible.

Vacant-land holding costs.Since 2019, holding costs on vacant land owned by individuals are denied unless the land is being actively used in a business. Interest, rates, and land tax on a block you're holding to develop later won't generate a deduction; they get added to the cost base for CGT purposes instead.

Initial-repair costs at purchase. Covered above, but worth repeating because it catches so many people. Anything that fixes a defect existing at settlement is capitalised, not expensed.

Professional fees: deductible, but only some

Tax-agent and accountancy fees for preparing your rental schedule and tax return are deductible in the year paid. So is the cost of attending an ATO audit if one comes up.

Legal fees for lease preparation (drafting a new lease, evicting a non-paying tenant, recovering unpaid rent through QCAT or VCAT) are deductible. Legal fees for the original property purchase are not deductible against rental income; they get capitalised into the cost base for capital gains tax purposes, which means they reduce your taxable gain on eventual sale rather than your income now.

Mortgage-broker feespaid directly by you (not the more common case of the broker being paid by the lender) are deductible as borrowing expenses. Borrowing expenses over $100 are spread across five years, not claimed in full upfront. This includes loan-establishment fees, lender's mortgage insurance, valuation fees, and title-search fees.

The worked example

Take a typical Brisbane investor on the 37 per cent marginal rate (taxable income $135,000 to $190,000 in 2025-26). They own one rental property bought three years ago for $720,000 with a $560,000 loan at 6.1 per cent.

Rental income: $30,000 a year ($580 a week net of vacancy).

Deductible expenses:

• Interest on the loan: $34,160
• Council rates: $2,400
• Water service charges: $900
• Landlord and building insurance: $1,800
• Strata levies (admin and sinking): $4,200
• Property-management fees and leasing: $2,640
• Repairs (gutters cleaned, tap replaced, hot-water element): $1,400
• Land tax: $1,300
• Accountant fee for last year's return: $440
• Depreciation (Division 43 only, post-2017 rules): $5,600

Total deductions: $54,840. Rental loss: $30,000 minus $54,840 equals $24,840. At the 37 per cent marginal rate plus the 2 per cent Medicare levy (so 39 per cent effective), the tax saving from offsetting that loss against salary is roughly $9,690.

Note what depreciation does in this picture. Cash going out the door is $49,240 (every deduction except the $5,600 of depreciation, which is non-cash). Rent coming in is $30,000. Real cash drain is $19,240. After the $9,690 tax refund, the net cost of holding the property is roughly $9,550 a year out of after-tax salary. Without the depreciation deduction the refund would be about $7,500 and the net cost roughly $11,740. The schedule alone is worth $2,190 a year on these numbers.

For the bigger picture of how the rental loss interacts with capital gains tax on eventual sale, the negative gearing in 2026 article works through the mechanism end-to-end. The deduction is real. It's also a second-order effect on top of the actual property thesis.

Common mistakes the ATO flags

Claiming travel. Still the most common disallowed item nine years after the rule changed. If your accountant lets it through, find a new accountant.

Claiming PPOR-period expenses. A property used as your home for eight months and rented for four can only deduct four-twelfths of the rates, interest, and insurance. The apportionment needs to track the days the property was genuinely available for rent, not the days you wished it was.

Double-claiming a renovation as repairs. Replacing a kitchen and claiming the $14,000 invoice as a current-year repair, while a quantity surveyor also capitalises the same kitchen into the Division 40 schedule. The ATO data-matches tradie invoices to depreciation schedules and finds these reliably.

Treating special body-corporate levies as ordinary levies. A $6,000 special levy for a new lift gets claimed in full as an immediate deduction when it should be capital works at 2.5 per cent a year. Often invisible until an audit cross-checks body-corporate minutes against the return.

Forgetting borrowing expenses after refinance. When you refinance, the undeducted portion of the original loan's borrowing expenses becomes immediately deductible in the year of refinance. Most landlords miss this and continue amortising over the original five years against a loan that no longer exists.

How to use this for your own numbers

Work backwards from the rent. Use the rental yield calculator to get the realistic net yield on whatever property you're modelling, sketch the interest bill against the rates and strata, then layer depreciation on top once you've got a quantity-surveyor estimate. The order matters because the underlying property thesis has to work on the cash numbers first; the tax deductions are a refinement, not a rescue.

For an existing portfolio, the highest-value half-day of work most landlords can do is sit down with a year of bank statements, the body-corporate annual report, and the agent's end-of-year summary. Categorise every line into the buckets above. The leakage almost always shows up in three places: missed depreciation (no schedule, or stale schedule), misclassified special levies, and forgotten borrowing-expense amortisation from an old refinance. Burbfinderwon't do your tax return for you, but the calculators get you to the defensible numbers your accountant needs to do it properly.
