Rental property is one of the better-understood parts of the Australian tax system — but "better-understood" is not the same as "straightforward". The ATO's general rule is straightforward enough: if an expense is incurred in earning or producing your assessable rental income, it is generally deductible against that income in the year you incur it. The trick lives in the edges. Below is a working guide to the deductions the ATO expects to see on a typical Australian residential rental return, with the framing an investor needs when the year-end conversation with their accountant actually happens.
Loan interest is the single biggest line on most rental returns. Interest on a loan taken out to acquire a rental property, or to fund improvements to it, is generally deductible in the year the interest accrues — provided the loan is genuinely used for an income-producing purpose. The redraw trap catches people out: you cannot redraw against the investment loan to fund a private expense (a holiday, personal car, a deposit on your own home) and still claim that interest component against rental income. If the loan purpose has shifted — refinancing from owner-occupied to investment is a common one — keep the refinance paperwork and a contemporaneous diary of what the new loan is now funding. Lenders do not owe the ATO an explanation; you do.
Depreciation comes in two flavours and the ATO expects you to handle them separately. Plant and equipment (Division 40 of the ITAA 1997) covers removable assets inside the property — carpet, hot water systems, air conditioning units, dishwashers, ovens, smoke alarms. Generally depreciated over the asset's effective life, with removable items under $300 sometimes claimed outright in the year of purchase. A quantity surveyor can produce a depreciation schedule that itemises every asset for you; the cost of the schedule itself is deductible. Capital works (Division 43) covers the building itself and any structural additions: generally 2.5% of construction cost per year over forty years from completion. If the property was built recently enough to have records of original construction cost, you have a Division 43 claim. If you bought an older property and have no records of post-1987 construction, the building allowance may not apply — which is one reason the price of a CGT-savvy quantity surveyor varies a lot by property age.
The repairs-versus-improvements line is where audits most often bite. A repair restores something to its original working condition — fixing a leaking tap, patching a cracked cornice, replacing a broken windowpane, repairing a stove element. Generally deductible in the year incurred. An improvement creates something new, or upgrades what was there, or fixes a fault that existed when you bought the property — a new bathroom, a kitchen renovation, rectifying pre-purchase defects, capital extensions. Generally capital and depreciated over the asset's effective life, not deducted upfront. The "initial repairs" trap is the specific one: repairs carried out to fix a problem that existed at the time of purchase are treated as capital by the ATO, even if they would otherwise look like ordinary repairs. Keep the pre-purchase building inspection report. If it mentions the defect you later fixed, the deduction may not be yours to claim.
For units and apartments, body corporate or strata levies are generally deductible to the extent they cover day-to-day operating costs: administrative fees, building insurance, cleaning of common areas, gardening of grounds, lift maintenance, repairs to common property. Some levies include a sinking fund contribution that is generally treated as a capital works component — your levies notice may distinguish between "admin fund" and "sinking fund" contributions. The admin portion is generally deductible; the sinking fund portion is generally capital and depreciated. Hold onto the annual notice and the AGM minutes; both are useful evidence if the ATO asks.
Insurance premiums for the rental property are generally deductible: building insurance, landlord insurance, contents insurance (if the property is furnished and you own the contents), and rent-loss insurance. Premiums paid in advance for a period spanning two financial years are split between them, not deducted entirely in the year of payment.
Council and water rates are also generally deductible when paid by the landlord. Some leases in some states flip water rates to the tenant — in that case the rate is no longer your expense and the deduction is the tenant's. Council rates remain the landlord's expense regardless of who pays the rent. Keep the annual rate notice; if part of it is a garbage or waste charge, the entire rate notice is generally deductible as a council-rate expense.
A bundle of smaller operating costs is typically deductible: gardening, lawn mowing, pest control treatments between tenancies, cleaning at the end of a tenancy, lease preparation and advertising, the letting fee paid to a property manager, and any sundry repairs under the agent's authority. None of these is individually large; together they make a meaningful difference to the net return figure on a property and to what you owe the ATO at year end.
Travel to inspect a rental property is more limited than most investors expect. The general rule: travel to inspect the property is generally deductible only if the trip's primary purpose is to perform an income-producing activity connected to the property — collecting rent in person from a distant property, attending an emergency repair, conducting an out-of-area inspection tied to a lease renewal or a dispute. Routine "checking in" trips, viewings of comparable properties, or trips driven primarily by a personal reason (visiting friends in the same town) are not deductible. The ATO's residential-property travel rules changed in 2017, and personal-general travel on residential investment properties remains restricted. Keep a contemporaneous note of why you went; a calendar entry tagging the trip's purpose a week after the fact reads as invented.
Negative gearing is a framing question rather than a deduction in itself. If your deductible expenses exceed your rental income for the year, the net loss can generally be offset against your other assessable income as an individual investor — reducing your overall tax bill. The same property held inside a company generally cannot pass a loss through to shareholders in the same way, because companies are taxed on net rental income at the company rate. Negative gearing is not a strategy the ATO has ever endorsed — they accept the mathematics of losses that genuinely arise, but they will scrutinise whether the property is held for a genuine income-producing purpose, or whether it is held primarily for capital growth with the rental stream as window dressing. Records of advertising for tenants, screening records, lease agreements and rent receipts are evidence of the genuine-purpose view.
Record-keeping is the cheapest deduction most investors ignore. The ATO requires you to keep records for five years from the date you lodge the relevant return (longer if you lodge late). Acceptable in any format: paper, digital scan, spreadsheet, accounting software. The records must be readable, retainable, and capable of being produced on request within a short timeframe — which means digital copies on a single phone or hard drive are not adequate. A practical habit is one folder per property, one sub-folder per financial year, and an end-of-year export from your bank that reconciles to the rent ledger. The ATO's question in an audit is rarely "did you spend this?" — it is "show me the receipt that proves you spent this on the rental property, dated in the financial year you claim it". Having the records ready turns a stressful review into a half-hour conversation.
This guide is general information for Australian residential landlords, not tax advice. The ATO's own rulings and the ITAA 1997 are the source of truth for any specific claim — particularly for depreciation rates, travel rules, and the negative-gearing framing specific to your holding structure. Where an expense sits on the line between deductible and capital, or where the property is held in a trust or company structure, a registered tax agent is the right next conversation. RentMetrics' annual report exports the data that supports each of these claims, but it does not replace the judgment of a tax professional reviewing your specific situation.

6 questions Australian landlords ask most
Plain-language answers to the deductions we get asked about most often.
Is the interest on my investment loan deductible?
Generally yes, in the year the interest accrues, so long as the loan was taken out to acquire, refinance or maintain a genuine income-producing rental property. You cannot redraw against the loan to fund a private expense and keep that interest component deductible — the ATO traces the use of borrowed funds. Keep the loan paperwork and a contemporaneous diary if the purpose of the loan changes.
Can I claim depreciation on a property I bought years ago?
You can generally claim depreciation on plant and equipment (Division 40) regardless of when the property was purchased, because the claim runs from the time each item is installed — including by the previous owner. Capital works (Division 43, the building itself) is more restrictive: it generally requires construction records dated after 1987, and your claim starts from the completion date. A quantity surveyor can produce the schedule needed to make both claims correctly.
What's the difference between repairs and improvements for tax purposes?
A repair restores something to its original working condition — fixing a leaking tap, patching a cornice, replacing a broken hot water system — and is generally deductible in the year incurred. An improvement creates something new, upgrades what was there, or fixes a fault that existed when you bought the property; that is capital and is generally depreciated over time, not deducted upfront. The "initial repairs" trap catches landlords who repair a pre-existing defect shortly after purchase; the ATO treats those repairs as capital.
Can I claim travel to inspect my rental property?
Generally only in limited cases where the trip is primarily for an income-producing purpose connected to the property — collecting rent in person from a distant property, attending an emergency repair, or resolving an issue tied to a tenancy dispute. Routine inspection trips, viewings of comparable properties, or trips with a personal primary reason are not deductible. The ATO tightened the residential-property travel rules in 2017. Keep a contemporaneous note of why you went, on the day itself.
What records do I need to keep for my rental property?
Keep records for at least five years from the date you lodge the relevant return (longer if you lodge late). Acceptable in any format that can be produced on request: paper, digital scan, accounting software, spreadsheet. The records need to show what the expense was, when you incurred it, what it was for, and that it relates to the rental property. A practical structure is one folder per property with one sub-folder per financial year, plus end-of-year bank exports reconciled to the rent ledger — so the ATO audit conversation becomes a half-hour retrieval job, not a scramble.
Are body corporate or strata levies deductible?
Generally yes for the administrative fund component — covering day-to-day operating costs like building insurance, common-area cleaning, gardening, lift maintenance, and repairs to common property. The sinking fund contribution is generally capital (depreciated, not deducted upfront), because it funds future capital works. Hold onto the annual levies notice and the AGM minutes; both are useful evidence if the ATO asks where the line was drawn.
