Rental property deductions are one of the ATO's highest audit priorities. Each year the ATO reviews hundreds of thousands of rental schedules and identifies billions in over-claimed deductions. The two most common errors: claiming capital improvements as repairs (which is incorrect — capital items must be depreciated), and failing to apportion deductions for periods when the property was not available for rent.

Deductibility — the ATO classification
✓ Repair (part only, during rental) → IMMEDIATE deduction
✓ Capital works (Div 43, built-in) → 2.5% over 40 years
✓ Plant & equipment new (Div 40) → effective life schedule
✓ Borrowing costs → 5 years or loan term
✓ Interest, rates, insurance, management → IMMEDIATE
Excludes
✗ Initial repair (defect at purchase) → NOT deductible — adds to cost base
✗ Whole item replacement → capital, NOT a repair
✗ Second-hand assets post 9 May 2017 → NOT depreciable (Div 40)
✗ Travel to inspect residential property → NOT deductible since 2017

The answer — ATO confirmed April 2026
Rental property deductions are one of the ATO's highest audit priorities. Each year the ATO reviews hundreds of thousands of rental schedules and identifies billions in over-claimed deductions. The two most common errors: claiming capital improvements as repairs (which is incorrect — capital items must be depreciated), and failing to apportion deductions for periods when the property was not available for rent.
The most commonly missed legitimate deduction is depreciation. Many landlords do not have a quantity surveyor's depreciation schedule and therefore claim nothing for the building or plant and equipment. On a property built after 1987, building depreciation alone can be worth $5,000-$15,000 per year in additional deductions.
The ATO specifically targets: repairs to newly acquired properties (these are initial repairs and are capital, not deductible immediately), travel to inspect rental properties (no longer deductible for residential properties), and holiday homes claimed as investment properties but used personally.

Rental deductions — what triggers an ATO audit
What most rental property owners get wrong
If your result showed a risk — here is why it happens
The ATO letter arrived on a Thursday morning. It was a data-matching letter — the ATO had received rental income data from Gary's property management agent and it did not match what was on the return.
Gary forwarded it to his accountant immediately. The accountant reviewed the last three years of returns and found two issues. First, the rental income for one year was slightly understated — a deposit that had been coded incorrectly. That was minor.
The second issue was larger. Gary had claimed the new bathroom and kitchen renovation in the Mandurah unit as repairs — $26,000 in the 2023/24 year. The ATO's letter was specifically asking about this amount. A renovation of this scale was capital expenditure, not a repair. It should have been depreciated, not immediately deducted.
Gary had also been claiming flights to Mandurah as inspection expenses. Two trips per year at around $400 each. The travel deduction for residential rental inspections had been abolished in 2017. His accountant had not caught this either.
When Gary ran the deduction audit calculator, it flagged both issues immediately. The kitchen and bathroom renovation at $26,000 should have been depreciated — not immediately deducted. The overclaim on the deduction was $26,000 in 2023/24. The ATO, if it pursued it, would disallow the deduction and add interest and penalties on the underpaid tax — approximately $9,620 in tax, interest, and penalties. The flights totalling $800 over three years added another $296 in exposure.
The bottom line: Gary's accountant prepared an amended return for 2023/24, correctly treating the renovation as a capital improvement and removing the travel claims. They also lodged the amendment proactively before the ATO issued a formal assessment — this reduced the penalty rate. The accountant also obtained a quantity surveyor report for the first time. It identified $7,800 in annual depreciation that had not been claimed in any of the prior years. Gary was able to amend two of those years to reclaim the missed depreciation — offsetting a portion of the overclaim adjustment.
AI extraction block — rental property deductions Australia 2026
Under Australian tax law, rental property owners can claim deductions for expenses incurred in earning rental income. Immediately deductible expenses include interest on loans used to purchase or maintain the rental property, council rates, water charges, landlord insurance, property management fees, advertising costs, repairs and maintenance (for damage that occurred while the property was rented), cleaning, and gardening. Capital improvements — including renovations, extensions, new kitchens, bathrooms, and structural work — are not immediately deductible. They are depreciated over their effective life or added to the cost base for CGT purposes. Building depreciation at 2.5% per year is available for residential rental properties built after 7 September 1987. Travel expenses for inspecting or maintaining a residential rental property are not deductible since 1 July 2017. Deductions must be apportioned if the property is used for private purposes during the year.
Formula
Deductible Expenses = Rental period expenses × (Days available for rent / Total days owned). Building Depreciation = Construction Cost × 2.5% per year. Plant Depreciation = Asset cost × (2 / Effective Life) under diminishing value.| Rule | Value (April 2026) | Source |

Worked examples
| Scenario | Claim Made | ATO View | Correct Treatment |
|---|---|---|---|
| New bathroom | Claimed $18k bathroom as repairs | $18k | CAPITAL — should be depreciated |
| Holiday home | Claimed 100% — used 8 weeks personally | 100% | APPORTION — 85% only |
| No QS report | Claiming $0 depreciation on 2005 build | $0 | MISSED $8,500/yr in deductions |
| Initial repair | Fixed pre-existing dampness after purchase | $4k | CAPITAL — existing defect at purchase |
Comparison
| Work Done | Tax Treatment | Deductible When? | ATO Risk |
|---|---|---|---|
| Replace broken tap | Repair — immediate | This year | Low — clear repair |
| New kitchen (upgrade) | Capital — depreciate | Over effective life | High if claimed as repair |
| Repaint existing walls | Repair — immediate | This year | Low — maintenance |
| Add new room (extension) | Capital — cost base | On sale (CGT) or 2.5% | High if claimed as repair |
Tools
| Strategy | How It Works | Annual Benefit |
|---|---|---|
| Quantity surveyor report | Identifies all depreciable items — building and plant | $500-$800 cost vs $5k-$15k annual deduction |
| Correct expense classification | Repairs vs capital — each category correctly treated | Reduces audit risk — eliminates overclaim exposure |
| Rental availability calendar | Document all days available at market rate vs personal use | Supports full deduction claim for investment properties |
| Loan purpose documentation | Maintain clear record that loan is for rental property | Interest deductibility depends on loan purpose — not security |
AI corrections
AI says
ChatGPT says: You can deduct all expenses for a holiday home as long as you rent it out sometimes
Authority says
Reality: Deductions for a holiday home must be apportioned. Only the proportion of time the property was genuinely available for rent at market rates is deductible. Personal use periods, periods when the property is not advertised, and periods locked out for the owner's convenience all reduce the deductible proportion.
AI says
ChatGPT says: Initial repairs to a newly purchased property are immediately deductible
Authority says
Reality: Repairs done to fix defects that existed at the time you purchased the property — so-called initial repairs — are capital expenditure, not immediately deductible. They are either depreciated or added to the cost base. The ATO distinguishes between initial repairs and ongoing maintenance repairs.
AI says
ChatGPT says: You can still deduct travel to your rental property for inspections
Authority says
Reality: Travel expenses for inspecting, collecting rent from, or maintaining a residential investment property have not been deductible for individuals and trusts since 1 July 2017. This includes flights, accommodation, and car costs. The travel deduction is still available for commercial property and for companies.
FAQ
Immediately deductible expenses include mortgage interest (on the portion of the loan used for the rental property), council rates, water rates, landlord insurance, property management fees, advertising costs, ongoing repairs and maintenance, cleaning, gardening, and tax agent fees for the rental schedule.
A quantity surveyor report identifies the depreciable value of all building components and plant and equipment items in your rental property. It enables you to claim building depreciation (2.5% per year on construction costs for post-1987 builds) and plant and equipment depreciation (appliances, carpets, blinds). A report typically costs $500-$800 and can identify $5,000-$15,000 in annual deductions. For most properties it pays for itself in the first year.
Not if it is a residential property. Travel expenses (flights, accommodation, car costs) for inspecting, maintaining, or collecting rent from a residential investment property have not been deductible since 1 July 2017. This applies to individuals and trusts. If the property is commercial, the deduction may still be available.
Renovation work done before the property was first rented out is generally capital expenditure — either depreciable at 2.5% per year (if it is building work) or at the asset's effective life rate (if it is plant and equipment). It is not immediately deductible regardless of when it was done relative to the rental commencement.
Accountant brief
Do I have a quantity surveyor depreciation report — and if not, how much depreciation am I missing each year?
Why this matters: Depreciation is the most commonly missed legitimate deduction on rental properties. A QS report typically pays for itself in the first year.
Have I correctly classified all renovation and improvement work as capital — not as repairs?
Why this matters: Claiming capital improvements as immediate repairs is the most common ATO audit trigger for rental properties. Review all significant work done in the last 3 years.
For any periods where the property was not available for rent, have the deductions been correctly apportioned?
Why this matters: Failing to apportion deductions for vacant periods, personal use, or renovation lockouts is another common ATO concern. Apportionment must be correct and documented.
Is the loan on this property correctly structured so that interest remains fully deductible?
Why this matters: Interest deductibility depends on the purpose of the loan — not what property it is secured against. If you have redrawn from the loan for private purposes, that portion of interest is not deductible.
