Property Depreciation Schedule Guide Australia: Maximise Your Tax Deductions

Depreciation is one of the most powerful and most overlooked tax deductions available to property investors in Australia. It is a non-cash deduction, meaning you claim a tax benefit for the wear and decline in value of your property and its assets without spending a single dollar. For many investors, a properly prepared depreciation schedule can unlock $5,000 to $15,000 in deductions per year, directly reducing taxable income and improving after-tax cash flow.

Yet a surprising number of investors either do not have a depreciation schedule at all, or have one that was poorly prepared and leaves thousands of dollars on the table. This guide explains exactly how property depreciation works in Australia, what you can claim, and why a quality depreciation schedule is one of the best investments you can make as a landlord.

What Is Property Depreciation?

Property depreciation is a tax deduction that recognises the gradual decline in value of a building and its contents over time. Just as a business can depreciate equipment and machinery, property investors can depreciate the structural elements of a building and the removable assets within it.

The Australian Taxation Office (ATO) allows two distinct categories of depreciation deductions for investment properties, each governed by different rules and rates.

Division 43: Capital Works Deductions

Division 43 covers the structural elements of the building itself, including walls, floors, roofs, doors, windows, built-in cupboards, and fixed plumbing. These are the components that form the permanent fabric of the property.

Key rules:

• Applies to buildings where construction commenced after 15 September 1987 (for residential properties)
• The deduction rate is 2.5% per year of the original construction cost
• Deductions continue for 40 years from the date construction was completed
• The deduction is based on the original construction cost, not the purchase price

Example: If a residential property was built in 2010 at a construction cost of $320,000, the annual Division 43 deduction would be:

$320,000 x 2.5% = $8,000 per year

Over the 40-year life, the investor can claim a total of $320,000 in building depreciation. If the property was purchased in 2026, there would be 24 years of Division 43 deductions remaining, worth approximately $192,000 in total claims.

For properties built before September 1987, Division 43 deductions are generally not available on the original building structure. However, any renovations or additions completed after that date may still qualify.

Division 40: Plant and Equipment Deductions

Division 40 covers removable or mechanical assets within the property. These are items that are not permanently fixed to the building structure and have their own independent effective life. Common Division 40 items include:

| Asset | Effective Life | Annual Depreciation Rate (Diminishing Value) | |---|---|---| | Carpet | 8 years | 25% | | Blinds and curtains | 7 years | 28.5% | | Hot water system | 12 years | 16.67% | | Air conditioning (split system) | 10 years | 20% | | Dishwasher | 8 years | 25% | | Smoke alarms | 6 years | 33.33% | | Clothes line | 5 years | 40% | | Garage door (electric) | 10 years | 20% | | Freestanding oven/cooktop | 12 years | 16.67% | | Light fittings | 5 years | 40% | | Exhaust fans | 10 years | 20% |

Division 40 deductions can be calculated using either the diminishing value method or the prime cost (straight line) method. The diminishing value method gives larger deductions in the early years and is generally preferred by investors who want to maximise short-term cash flow. The prime cost method spreads the deduction evenly over the asset's effective life.

Diminishing value example (carpet valued at $4,000, 8-year life):

• Year 1: $4,000 x 25% = $1,000
• Year 2: $3,000 x 25% = $750
• Year 3: $2,250 x 25% = $562

Prime cost example (same carpet):

• Year 1: $4,000 / 8 = $500 per year (every year for 8 years)

The 2017 Budget Changes: What You Must Know

In the 2017-18 federal budget, the government introduced significant changes to depreciation rules for second-hand properties. These changes, which took effect from 1 July 2017, directly affect what investors purchasing existing properties can claim.

Before 1 July 2017: Investors who purchased an existing property could claim Division 40 depreciation on all plant and equipment assets within the property, based on their estimated remaining value at the time of purchase.

After 1 July 2017: Investors who purchase a previously used residential property can no longer claim Division 40 depreciation on existing plant and equipment that was installed by a previous owner. You can only claim Division 40 deductions on assets that you purchase and install yourself.

What this means in practice:

• If you buy a 10-year-old house with existing carpet, blinds, a hot water system, and air conditioning, you cannot depreciate those items even though they have remaining useful life.
• If you replace the carpet or install a new air conditioner after purchase, you can depreciate the new assets because you are the one who incurred the cost.
• Division 43 (capital works) deductions are unaffected by the 2017 changes. You can still claim 2.5% of the original construction cost regardless of whether you are the first owner or the fifth.

This change makes the distinction between Division 40 and Division 43 even more critical. For investors buying established properties, Division 43 is now the primary source of depreciation deductions, and a quality depreciation schedule that accurately determines the original construction cost is essential.

For investors buying brand new properties, the 2017 changes have no impact. You are the first owner of all plant and equipment assets, so you can claim the full Division 40 deductions from day one. This is one reason depreciation benefits are significantly higher for new builds compared to established properties.

New Property vs Old Property: Depreciation Comparison

The age and type of property you purchase has a dramatic impact on the depreciation deductions available to you. Here is a realistic comparison:

| Category | New Apartment (2025 build, $650,000) | Established House (2005 build, $650,000) | |---|---|---| | Division 43 (building) | ~$10,000/year | ~$6,500/year | | Division 40 (plant & equipment) | ~$5,000 - $8,000/year (early years) | $0 (2017 rules, unless you renovate) | | Total Year 1 deductions | ~$15,000 - $18,000 | ~$6,500 | | Tax saving (37% bracket) | ~$5,500 - $6,600 | ~$2,400 |

The difference is substantial. A new property can generate nearly three times the depreciation deductions of an established one, which directly affects the property's after-tax holding cost. This is a factor that should influence your purchase decision, particularly when comparing properties at similar price points.

However, this does not mean new properties are always the better investment. Established properties in premium locations may deliver superior capital growth that outweighs the depreciation advantage. The key is to model the full financial picture, including depreciation, when comparing opportunities. Tools like PropBuyAI can help by providing comparable sales data and rental yield analysis for both new and established properties, making it easier to compare on a like-for-like basis. Understanding how depreciation interacts with negative gearing is also important; see our negative gearing guide for a worked example.

How to Get a Depreciation Schedule

A depreciation schedule must be prepared by a qualified quantity surveyor (also known as a construction cost estimator). The ATO requires that the schedule be prepared by a professional with appropriate qualifications and that it be based on an inspection of the property or, in some cases, available construction records.

The process:

1. Engage a quantity surveyor. Most firms operate nationally and can arrange inspections in any state. Reputable firms include BMT Tax Depreciation, Washington Brown, Duo Tax, MCG Quantity Surveyors, and DEPPRO.
2. Property inspection. The surveyor inspects the property (usually taking 30 to 60 minutes) to identify all depreciable assets, measure the building, and assess construction costs.
3. Schedule preparation. The surveyor prepares a detailed report listing every claimable item under Division 40 and Division 43, with year-by-year deductions for the remaining depreciable life.
4. Submit to your accountant. Your tax agent uses the schedule to prepare your annual tax return. The schedule is valid for the life of the property; you do not need a new one each year unless you renovate.

Cost: A standard depreciation schedule costs between $600 and $800 including GST. Some firms offer discounts for multiple properties. The cost of the schedule itself is tax deductible in the year it is incurred.

Is it worth it? Almost always. A $700 schedule that unlocks $8,000 in annual deductions represents a return of more than 10:1 in the first year alone. Over the life of a typical investment property, a depreciation schedule can generate $100,000 to $200,000 in total deductions. Not having one is leaving money on the table.

What Happens When You Sell?

Depreciation deductions claimed during your ownership period affect your capital gains tax (CGT) calculation when you sell. Specifically, Division 40 depreciation deductions reduce the cost base of the property for CGT purposes. This means you may pay more CGT on sale because the ATO considers that you have already recovered some of the asset's value through depreciation claims.

Division 43 deductions do not reduce the cost base in the same way. This makes Division 43 (capital works) depreciation particularly valuable from a long-term tax planning perspective.

Example:

• You claimed $30,000 in Division 40 depreciation over your ownership period
• Your cost base is reduced by $30,000, increasing your capital gain by the same amount
• At the 50% CGT discount (for assets held more than 12 months) and a 37% marginal tax rate, the additional tax on sale would be approximately $5,550
• But you received $11,100 in tax savings from the depreciation deductions during the holding period (37% of $30,000), netting you $5,550 ahead

In nearly every scenario, claiming depreciation during the holding period and paying slightly more CGT on sale produces a better outcome than not claiming at all. The time value of money means tax savings received today are worth more than tax paid in the future. Your accountant can model the specific impact for your situation.

Common Depreciation Mistakes

Not getting a schedule at all. This is the most expensive mistake. Every investment property built after 1987 is eligible for Division 43 deductions at a minimum. Failing to claim them is equivalent to voluntarily paying more tax.

Using an unqualified preparer. The ATO requires depreciation schedules to be prepared by a quantity surveyor with appropriate qualifications. Schedules prepared by accountants, real estate agents, or unqualified estimators may not be accepted by the ATO and could trigger an audit.

Not updating after renovations. If you renovate your investment property, the new work creates additional Division 43 deductions (for structural work) and Division 40 deductions (for new fixtures and fittings). Your quantity surveyor can prepare an addendum to your existing schedule to capture these.

Claiming Division 40 on second-hand assets post-2017. Some investors (or their accountants) inadvertently claim Division 40 depreciation on existing plant and equipment in properties purchased after 1 July 2017. This is not allowed and can result in amended assessments and penalties.

Choosing the wrong depreciation method without advice. The diminishing value and prime cost methods produce different cash flow outcomes. Discuss with your accountant which method best aligns with your investment strategy before the schedule is prepared.

How PropBuyAI Helps

Depreciation is just one piece of the investment puzzle. To make a truly informed purchase decision, you need to understand how depreciation deductions interact with rental yield, comparable sales values, and your overall holding costs. PropBuyAI's AI-powered property analysis brings these data points together for any Australian listing, giving you a comprehensive view of a property's investment potential. By analysing comparable sales and rental data alongside the property's age and type, you can assess whether the depreciation benefits of a new build outweigh the growth potential of an established property in a stronger location.

Key Takeaways

• Every investment property investor should have a depreciation schedule. The cost ($600 to $800) is trivial compared to the potential deductions of $5,000 to $15,000+ per year.
• Division 43 (capital works) allows you to claim 2.5% of the building's construction cost per year for properties built after September 1987. This applies regardless of whether you are the original owner.
• Division 40 (plant and equipment) covers removable assets like carpet, blinds, and appliances. Since the 2017 budget changes, you can only claim Division 40 on assets you install yourself in second-hand properties.
• New properties offer significantly higher depreciation than established ones, which should factor into your purchase analysis.
• Depreciation reduces your cost base for CGT purposes, but the net effect is still positive in almost all cases due to the time value of money.
• Engage a qualified quantity surveyor to prepare your schedule and update it whenever you complete renovations.

Depreciation is not a bonus or an afterthought. It is a core component of investment property tax planning that directly affects your annual cash flow and after-tax returns. If you do not have a depreciation schedule for your investment property, getting one should be your next step. And when evaluating your next purchase, use PropBuyAI to analyse the property's rental yield and comparable sales alongside its depreciation potential.

Sample Depreciation Schedule: What It Actually Looks Like

To make this concrete, here is a worked example based on a typical investment property. The numbers below are illustrative but realistic, reflecting the kind of schedule a quantity surveyor would prepare.

The property: A 5-year-old, 3-bedroom house purchased for $650,000. The quantity surveyor estimates the original construction cost at $350,000.

Division 43 (capital works): The building qualifies for the standard 2.5% rate, calculated on the original construction cost.

$350,000 x 2.5% = $8,750 per year

This deduction remains constant each year for the remaining 35 years of the building's depreciable life.

Division 40 (plant and equipment): Assuming you are the original owner (or purchased before 1 July 2017, or have replaced these items yourself), the following assets are identified during the inspection. We will use the prime cost (straight line) method for clarity.

| Asset | Estimated Value | Effective Life | Annual Deduction | |---|---|---|---| | Air conditioning (split system) | $3,500 | 10 years | $350 | | Carpet | $4,000 | 8 years | $500 | | Blinds | $2,000 | 5 years | $400 | | Dishwasher | $1,200 | 6 years | $200 | | Hot water system | $2,500 | 12 years | $208 | | Smoke alarms | $800 | 6 years | $133 | | Total Division 40 | $14,000 | | $1,791 |

Combining both divisions, the year-by-year deductions look like this:

| Year | Division 43 | Division 40 | Total Deduction | |---|---|---|---| | 1 | $8,750 | $1,791 | $10,541 | | 2 | $8,750 | $1,791 | $10,541 | | 3 | $8,750 | $1,791 | $10,541 | | 4 | $8,750 | $1,791 | $10,541 | | 5 | $8,750 | $1,791 | $10,541 |

Note that with the prime cost method, the Division 40 figure stays flat until individual assets reach the end of their effective life. In year 6, the blinds would be fully depreciated and drop out, reducing the Division 40 total. With the diminishing value method, deductions would be higher in the early years and taper over time.

Tax Savings at Different Marginal Rates

Your actual cash benefit depends on your marginal tax rate. Using the Year 1 total deduction of $10,541:

| Marginal Tax Rate | Tax Saving (Year 1) | |---|---| | 32.5% | $3,426 | | 37% | $3,900 | | 45% | $4,743 |

At the 45% marginal rate, this property would save you nearly $4,750 in tax in the first year alone, and similar amounts for each of the following years. Over five years, that is close to $24,000 returned to your pocket through depreciation deductions, all without spending anything beyond the initial $600 to $800 schedule fee.

Frequently Asked Questions

What is a property depreciation schedule?

A property depreciation schedule is a detailed report prepared by a qualified quantity surveyor that lists every depreciable asset in your investment property and calculates the tax deductions you can claim each year. It covers both the building structure (Division 43) and removable assets like carpet, blinds, and appliances (Division 40). The schedule is valid for the life of the property, and the $600 to $800 cost is itself tax deductible.

What is the difference between Division 40 and Division 43 depreciation?

Division 43 covers the building structure itself, including walls, floors, and the roof, and is claimed at 2.5% of the original construction cost per year for 40 years. Division 40 covers removable plant and equipment items like carpet, air conditioning, and appliances, which are depreciated over their individual effective lives (typically 5 to 12 years). Since the 2017 budget changes, Division 40 on second-hand assets can only be claimed if you installed the items yourself.

How long can you claim depreciation on an investment property?

Division 43 (capital works) deductions can be claimed for 40 years from the date construction was completed, at a rate of 2.5% per year. Division 40 (plant and equipment) deductions vary by asset, with effective lives ranging from 5 years for light fittings to 12 years for hot water systems. Properties built after 15 September 1987 are eligible for Division 43 claims. For a full breakdown of how depreciation interacts with your other tax deductions, see our negative gearing guide.

How much does a depreciation schedule cost in Australia?

A standard depreciation schedule costs between $600 and $800 including GST. The fee is tax deductible in the year it is incurred. Given that a typical schedule unlocks $5,000 to $15,000 in annual deductions, the return on investment is more than 10:1 in the first year alone. Over the life of a typical investment property, a depreciation schedule can generate $100,000 to $200,000 in total deductions. Use our Depreciation Estimator to model your property's potential deductions.

Do new properties get better depreciation deductions than established properties?

Yes, significantly. A new property can generate $15,000 to $18,000 in first-year deductions compared to roughly $6,500 for an established property at a similar price point. This is because new property owners can claim both Division 43 and full Division 40 deductions, while owners of second-hand properties purchased after 1 July 2017 can only claim Division 40 on assets they install themselves. Use PropBuyAI's property analysis to compare rental yields and holding costs for new versus established properties.
