ATO Tax Depreciation in Australia: How to Maximise Your Investment Property Deductions
Depreciation is one of the most underutilised tax deductions available to Australian property investors. Unlike most expenses, you claim depreciation without spending a dollar — it is a paper deduction for the natural wear and tear of your property and its contents. Yet research by quantity surveying firms consistently finds that over 80% of Australian property investors are not claiming their full depreciation entitlement.
Over a typical investment property held for 10 years, a well-structured depreciation schedule can deliver $50,000–$120,000 in additional tax deductions, translating to $16,000–$40,000 in real tax savings depending on your marginal rate.
Division 40 vs Division 43 — The Two Types of Depreciation
The ATO splits investment property depreciation into two distinct categories under the Income Tax Assessment Act 1997:
Division 40 — Plant and Equipment
Division 40 covers removable assets — things that can be detached from the property without causing structural damage. Common examples include:
- Air conditioning units and ceiling fans
- Carpets and floating timber floors
- Dishwashers, ovens, and range hoods
- Hot water systems
- Blinds and curtains
- Solar panels and batteries
- Security systems
Each asset has an ATO-stipulated effective life — the expected years of useful life. For example, carpet has an effective life of 8 years; a dishwasher 6 years; an air conditioner 10 years. Deductions are calculated either using the Diminishing Value (DV) or Prime Cost (PC) method.
Important change for residential property: Since 1 July 2017, Division 40 deductions for residential investment property are only available on assets you install yourself (new assets) — not on second-hand assets that were in the property when you purchased it. This restriction does not apply to commercial property or to new residential builds purchased from the developer.
Division 43 — Capital Works
Division 43 covers the structural elements of the building — walls, roofs, floors, windows, plumbing, wiring, and fixed features. The deduction rate is fixed by the ATO:
- Residential property: 2.5% per year over 40 years
- Non-residential (commercial) property built after 1987: 4% per year over 25 years
Division 43 is only available on properties built after 15 September 1987 for residential, and 20 July 1982 for commercial. Older properties cannot claim capital works deductions, though they may still have Division 40 assets.
Diminishing Value vs Prime Cost — Which Method is Better?
| Feature | Diminishing Value (DV) | Prime Cost (PC) |
|---|---|---|
| Year 1 deduction | Higher | Lower |
| Later year deductions | Decrease each year | Equal each year |
| Total lifetime deductions | Equal (both reach zero) | Equal |
| DV formula | Opening value × (200% ÷ effective life) | — |
| PC formula | — | Cost × (100% ÷ effective life) |
| Best for | Maximising early cash flow | Predictable annual deductions |
Most property investors and accountants prefer the Diminishing Value method because front-loading deductions improves cash flow in the critical early years of a property investment when holding costs are highest.
Instant Asset Write-Off for Small Businesses
Small businesses with aggregated turnover below $10 million can immediately deduct the full cost of eligible assets under $20,000 in the year of purchase (2024–25). This removes the need to depreciate over the asset's effective life and provides an immediate cash flow benefit. Always confirm current thresholds with your tax agent as these change annually.
Getting a Quantity Surveyor Report
For investment properties, the ATO requires a depreciation schedule (also called a tax depreciation report) prepared by a qualified quantity surveyor for capital works claims. The cost of the report (typically $400–$700) is tax deductible and pays for itself within the first year of claimed deductions — often many times over.
This calculator provides indicative estimates only. Depreciation deductions depend on your specific property, assets, purchase date, and individual circumstances. Always consult a registered tax agent or quantity surveyor for a formal depreciation schedule. ATO rates are based on LI 2025/20.
