How Rental Property Depreciation Works for Australian Investors: A Complete Guide

As a property investor in Australia, you’re likely familiar with the common tax deductions like mortgage interest, council rates, and property management fees. However, one of the most valuable yet often misunderstood deductions is rental property depreciation. Depreciation can significantly reduce your taxable income, improving your cash flow and overall return on investment. But navigating the rules can be complex, especially with recent legislative changes. This comprehensive guide explains everything you need to know about rental property depreciation, from the two types of deductions to eligibility criteria, depreciation schedules, and how to stay compliant with the Australian Taxation Office (ATO).


What is Rental Property Depreciation?

Rental property depreciation is a tax deduction that allows property investors to claim the decline in value of their investment property and its assets over time. The Australian Taxation Office (ATO) recognises that buildings and their fixtures and fittings wear out over time, and this wear and tear can be claimed as a non-cash deduction against your rental income. This means you can reduce your taxable income without actually spending any additional money each year.

Depreciation is governed by two key pieces of legislation: Division 40 (plant and equipment assets) and Division 43 (capital works deductions). Understanding the distinction between these two categories is crucial for maximising your claims.

The Two Types of Depreciation

1. Capital Works Deductions (Division 43): This relates to the structural elements of the building, such as concrete, brickwork, walls, roofing, windows, and fixed plumbing and electrical systems. For residential properties where construction commenced after 15 September 1987, you can generally claim 2.5% per year for 40 years. For certain short-term traveller accommodation, the rate may be 4% per year for 25 years.

2. Plant and Equipment Assets (Division 40): These are the easily removable or mechanical assets within the property, like carpets, blinds, air conditioning units, ovens, dishwashers, and hot water systems. Each asset has an effective life set by the ATO, and you deduct a percentage of its decline in value each year.

It’s important to note that since 1 July 2017, there have been significant changes to the rules around claiming plant and equipment assets for second-hand properties. We’ll cover this in detail later.

Eligibility Criteria for Claiming Depreciation

Not every property owner can claim depreciation. To be eligible, you must:

• Own the property and generate rental income: The property must be used to produce assessable income. If the property is your private residence and you don’t rent it out, you generally cannot claim depreciation. If you only rent out part of the property, you can claim a portion of the depreciation.
• The property must be income-producing: If the property is available for rent but vacant, you can still claim depreciation as long as you are actively marketing it for lease.
• Construction date matters: For capital works deductions, residential properties must have commenced construction after 15 September 1987. However, there are exceptions for certain commercial properties and short-term traveller accommodation.
• Plant and equipment rules: Since 9 May 2017, you can only claim depreciation on plant and equipment assets if you purchased the asset yourself (i.e., it was not existing in the property when you bought it, unless you’re using the property for commercial purposes or are a corporate tax entity that satisfies certain conditions). This means that for most residential investors buying second-hand properties, you cannot claim depreciation on existing plant and equipment assets, but you can still claim on new assets you install.

Key Legislative Changes: The 2017 Amendments

On 9 May 2017, the Australian Government introduced the Treasury Laws Amendment (Housing Tax Integrity) Act 2017. These changes limited plant and equipment depreciation deductions to assets that were actually purchased by the investor. In simple terms:

• If you bought a new investment property (never been lived in), you can claim depreciation on both capital works and plant and equipment assets.
• If you bought an established (second-hand) residential property after 9 May 2017, you can still claim capital works deductions if the building qualifies, but you cannot claim depreciation on existing plant and equipment assets that were in the property at the time of purchase. However, if you buy new plant and equipment assets for the property (e.g., you install a new dishwasher), you can claim depreciation on those new assets.

There are some exceptions, such as if you are carrying on a business of property investing or if you are a corporate tax entity, but these are rare for individual investors. Always check with a qualified tax professional.

How Depreciation Schedules Work

A depreciation schedule is a comprehensive report prepared by a qualified quantity surveyor that outlines all the depreciation deductions you can claim for your investment property. The ATO allows property investors to use a quantity surveyor’s report to estimate the construction cost and asset values for depreciation purposes. The schedule breaks down the capital works and plant and equipment deductions over the life of the property.

What’s Included in a Depreciation Schedule?

• Capital Works Breakdown: The estimated construction cost of the building (if built after 1987) and the annual deduction amount.
• Plant and Equipment Schedule: A detailed list of all removable assets, their effective life, and the decline in value each year using the diminishing value or prime cost method.
• Projected Deductions: A year-by-year forecast of the total depreciation deductions you can claim, typically for up to 40 years.

Why You Need a Quantity Surveyor

While you might be tempted to estimate these values yourself, the ATO requires that capital works deductions be based on a report from a qualified professional, such as a quantity surveyor, unless you have actual construction cost records. Quantity surveyors are experts in estimating building costs and asset values, and their reports are accepted by the ATO. The cost of the depreciation schedule itself is also tax-deductible.

Maximising Your Depreciation Deductions

To ensure you’re getting the most out of your depreciation deductions, consider the following strategies:

1. Obtain a Tax Depreciation Schedule Early

If you’ve purchased an investment property, arrange for a depreciation schedule as soon as possible. Many investors miss out on thousands of dollars in deductions simply because they didn’t know about depreciation or thought their property was too old. Even properties built before 1987 can have plant and equipment assets that may be depreciable, and renovations can trigger capital works deductions.

2. Choose the Right Depreciation Method

For plant and equipment assets, you can choose between the diminishing value method and the prime cost method. The diminishing value method gives you higher deductions in the early years of ownership, which can be beneficial if you need immediate tax relief. The prime cost method spreads the deduction evenly over the asset’s effective life. You can switch methods for different assets, but once you choose a method for an asset, you generally must stick with it.

3. Don’t Forget Low-Value Pooling

Assets costing less than $1,000 (or with an opening written-down value of less than $1,000) can be allocated to a low-value pool. This allows you to deduct them at a faster rate: 18.75% in the year of allocation and 37.5% each year thereafter. This can accelerate your deductions significantly.

4. Claim Scrapping for Renovations

If you renovate your investment property and remove existing assets (like old carpets or appliances), you may be able to claim an immediate deduction for the remaining written-down value of those assets in the year they are scrapped. This is known as a “scrapping deduction” and requires a quantity surveyor to value the assets before removal.

5. Review Your Depreciation Schedule Regularly

If you make improvements or add new assets to the property, update your depreciation schedule. New assets mean new deductions, and you don’t want to miss out.

Common Mistakes to Avoid

Depreciation can be a minefield if you’re not careful. Here are some pitfalls to watch out for:

• Claiming on Ineligible Properties: Attempting to claim capital works on a pre-1987 residential property that hasn’t been renovated can lead to ATO audits and penalties.
• Claiming Plant and Equipment on Second-Hand Properties: Since the 2017 changes, many investors incorrectly claim depreciation on existing assets. Ensure you understand the rules.
• Not Adjusting for Private Use: If you use the property for private purposes (e.g., holiday home) for part of the year, you must apportion your deductions based on the time it was rented vs. private use.
• DIY Depreciation Schedules: Using a non-qualified person to estimate construction costs can result in disallowed claims. Always use a registered quantity surveyor.
• Overlooking Renovation Depreciation: If you renovate, you may be entitled to capital works deductions on the renovation cost, even if the original building is pre-1987.

The Role of Depreciation in Your Investment Strategy

Depreciation is not just a tax benefit; it’s a powerful tool that can improve your property’s cash flow and make holding an investment property more affordable. For many investors, depreciation can turn a negatively geared property into a positively geared one, or at least reduce the out-of-pocket expenses.

Consider this example: An investor purchases a new apartment for $600,000. The depreciation schedule reveals $10,000 in capital works deductions and $8,000 in plant and equipment deductions in the first year. Combined with other deductions like interest and expenses, the total tax deduction could be substantial, potentially saving thousands in tax.

Recent ATO Focus and Compliance

The ATO has been increasingly scrutinising rental property deductions, including depreciation. In 2025, the ATO announced a continued focus on rental property claims, using data-matching technology to identify discrepancies. Common red flags include:

• Claiming depreciation on properties that are not genuinely available for rent.
• Incorrectly claiming plant and equipment on second-hand assets.
• Inflating construction costs without a qualified report.

To stay compliant:

• Keep detailed records of all expenses and depreciation schedules.
• Ensure your depreciation schedule is prepared by a registered tax agent or quantity surveyor.
• Review your claims with a tax professional, especially if your circumstances change.

FAQ

Can I claim depreciation on my principal place of residence?

No, you generally cannot claim depreciation on your main home because it is not used to produce income. However, if you rent out a portion of your home (e.g., a granny flat) or use it for business purposes, you may be able to claim a proportional deduction. Any claim will affect the capital gains tax exemption when you sell the property.

What if my property was built before 1987?

You cannot claim capital works deductions if construction commenced before 16 September 1987 (unless it has been substantially renovated). However, you may still be able to claim depreciation on plant and equipment assets if you purchased them new and they are used for income production. Renovations after 1987 may also qualify for capital works deductions.

How much does a depreciation schedule cost, and is it worth it?

A depreciation schedule typically costs between $400 and $700, depending on the property’s complexity. Given that the first year’s deductions can often be thousands of dollars, the cost is usually recovered many times over. The fee is also tax-deductible.

Can I backdate my depreciation claims?

Yes, you can amend previous tax returns to claim depreciation you missed, generally up to two years from the date of assessment. However, it’s best to get a schedule as soon as possible to avoid missing out on deductions.

Do I need a new depreciation schedule if I renovate?

If you undertake significant renovations, you should update your depreciation schedule to include the new capital works and any new plant and equipment assets. A quantity surveyor can prepare an addendum to your existing schedule.
