Property depreciation is one of the best tax deductions available to Australian property investors. Yet it is also one of the least understood aspects of property investment. Many owners miss out on thousands of dollars every financial year because they rely on common misconceptions or poor advice.
The rules around tax depreciation are easier than they seem. When you know what expenses can be claimed, you can increase your cash flow, reduce your taxable income, and protect your investment. This article explains the 10 most common property depreciation myths in clear and simple terms. With the facts, you will be able to claim depreciation deductions with confidence and avoid costly errors at tax time.
When you purchase an investment property, the building and its contents wear out over time. The ATO lets investors claim this natural loss in value as a tax deduction. This process is called property depreciation.
There are two main categories:
- Division 40 – Plant and Equipment: Items that can be replaced or removed, such as carpets, blinds, ovens, and hot water systems. Each has an effective life set by the ATO.
- Division 43 – Capital Works: The building structure, such as walls, windows, roofing, and kitchens. Residential buildings built after 15 September 1987 can typically be claimed at 2.5% a year for 40 years.
To calculate these depreciation deductions, you need a tax depreciation schedule. This report is prepared by a qualified Quantity Surveyor and ensures your claims are accurate, compliant with ATO requirements, and maximises your benefits.
Myth 1: Older Properties Yield No Depreciation
Many property investors think only new properties qualify for depreciation. This is false.
For capital works (Division 43), buildings built after 15 September 1987 can be claimed for up to 40 years. Even if a property is 20 years old, it may still have 20 years of deductions left.
If a property was built before 1987, you may still be able to claim depreciation on any qualifying renovations or structural improvements carried out after 27 February 1992. This means that even if the original building itself is too old to attract deductions, any extensions, refurbishments, or upgrades performed since then could still provide substantial depreciation benefits.
The rules around plant and equipment (Division 40) changed on 9 May 2017. Investors who purchased second-hand residential properties after this date can no longer claim depreciation on existing, previously used assets such as carpets, blinds, ovens, or hot water systems. These items are considered second-hand, so deductions are restricted.
Older properties often contain hidden value, especially when they have been upgraded. A Quantity Surveyor can uncover these deductions and make sure nothing is missed, helping smart investors optimise their tax outcomes.
Myth 2: Investors Cannot Claim Depreciation on Improvements or Assets Without Receipts
It is a myth that receipts are required for every asset or renovation. While records are helpful, they are not the only option.
The ATO allows Quantity Surveyors to estimate construction and renovation costs. They are recognised experts in building costs and asset values.
This means you can still claim depreciation on improvements, even if the work was done years ago and paperwork is missing. A professional tax depreciation schedule will set this out clearly, ensuring you don’t miss out on eligible deductions.
Myth 3: Depreciation Figures on Houses and Apartments is the Same
Houses and apartments do not always offer the same depreciation opportunities.
Apartments often generate extra deductions because investors can claim on shared areas like lifts, gyms, hallways, and pools. These items fall under plant and equipment (Division 40) and are shared across all units.
Houses do not have these shared facilities. Their deductions are usually limited to the building structure and internal assets.
This is why apartments can sometimes produce higher depreciation claims than houses, depending on the age, construction costs, and inclusions, as well as rental demand and location factors.
Myth 4: Investors Need to Come Back Every Year to Continue Claiming Depreciation
Some investors believe they must arrange a new depreciation schedule each year. This is incorrect.
A depreciation schedule is a one-off report that lasts up to 40 years. It sets out what can be claimed every financial year based on the property’s building structure and assets.
You will need to update your schedule if you carry out major renovations on your property. Otherwise, the same schedule will apply year after year.
This makes it one of the most cost-effective tools available to property investors, helping them build wealth and maximise tax benefits over the long term.
Myth 5: My Building is Better Than Others, Why Can’t I Claim It Faster
Some owners think their property deserves a faster depreciation rate because it is built to a higher standard. The ATO does not allow this.
Depreciation is based on fixed effective lives for assets and legislated rates for capital works. These rates apply equally across all properties, regardless of quality.
What a higher-quality or luxury build does influence is the depreciation amount. Premium finishes and higher construction costs generally mean larger total deductions, because the claim is a percentage of the original cost. However, the rate at which those deductions are applied remains the same.
This means a luxury home and a modest unit built in the same year are subject to the same ATO-set rates, but the dollar value of deductions will often be greater for the more expensive build.
Myth 6: My Accountant Can Do My Depreciation
Many investors assume their accountant can prepare a tax depreciation schedule. This is not the case.
Accountants are valuable when lodging tax returns, but they are not qualified to estimate construction costs or calculate depreciation deductions. Quantity surveyors are one of the few professions recognised by the ATO who can calculate the cost of items for depreciation purposes.
Quantity surveyors inspect the property, measure construction costs, and identify assets. Your accountant then uses the report to apply the deductions. Both professionals work together, but only a qualified quantity surveyor can produce a valid schedule.
Myth 7: I Can’t Claim Renovations Completed by a Previous Owner
Renovations do not need to be completed by you to qualify. If a previous owner upgraded the property, you may still be able to claim any remaining depreciation deductions.
Improvements like kitchens, bathrooms, extensions, and structural upgrades all qualify under capital works (Division 43) and may be claimed if they are still within the 40-year effective life period. For example, if the previous owner completed renovations in 2012 and you purchased the property in 2025, you may still be eligible to claim the remaining 27 years of depreciation on those capital works.
A Quantity Surveyor can estimate the market value of these works and include them in your schedule, even if receipts are not available.
Myth 8: More Expensive Assets Depreciate Faster
While the depreciation rate is set by the effective life of an asset and doesn’t change, more expensive items will generate larger overall deductions because the rate is applied to a higher cost.
For example, a $900 dishwasher and a $2,000 dishwasher may both depreciate at the same rate.
In fact, cheaper items can be claimed faster in some cases. Assets worth less than $1,000 can go into a low-value pool for quicker write-offs. Items under $300 can often be claimed immediately.
The price tag does not always drive the deduction. The ATO’s classification does.
Myth 9: As Soon as I Pay For an Asset or Capital Work, I Can Claim It
You cannot claim depreciation as soon as you pay for something.
For plant and equipment (Division 40), deductions start only when the asset is installed and ready for use. Simply buying it is not enough.
For capital works (Division 43), claims begin once construction is finished and the property is available for rent.
Understanding these rules helps you claim at the right time and stay compliant with tax deductibility requirements.
Myth 10: If I Delay Getting a Depreciation Schedule, I Lose My Chance to Claim Depreciation
Many investors think they have missed out if they delay getting a depreciation schedule. This is not true.
We can retrospectively adjust the depreciation schedules to start from the rental date to any extent. However, the ATO allows you to amend up to two previous tax returns to claim any missed depreciation deductions. Any amendments further than two years, may require you to lodge an amendment.
Even if your property is older or you have delayed, there is usually still value to unlock. Acting now means you stop leaving money unclaimed and improve your cash flow.
Speak With Duo Tax About Property Depreciation
Depreciation is one of the best ways to improve the cash flow of a rental property and reduce taxable income. However, myths and misinformation mean many owners lose money. Believing that older properties do not qualify, that you need receipts for everything, or that accountants prepare schedules are just a few of the common myths costing investors thousands each year.
The reality is clear. Tax depreciation applies to both new and old properties. Renovations add further value. A tax depreciation schedule is a one-off, tax-deductible investment that can last up to 40 years. With the right advice and strategy, you can claim confidently and stay in line with ATO rules.
If you own an investment property and have not yet arranged a depreciation schedule, now is the time. Speak with the team at Duo Tax to make sure you are claiming every deduction you are entitled to and maximising your long term capital growth and financial goals.
