Property Depreciation: A Complete Guide to Division 40 and Division 43 Claims

Property depreciation is the second largest deduction available to Australian property investors, yet many investors miss thousands of dollars in tax deductions each year. Whether you own a rental property or a residential investment property, having a property depreciation schedule Australia investors rely on is essential. This guide outlines what you need to know about tax depreciation schedules and how to maximise deductions on your investment property.

What Is Property Depreciation?

Property depreciation is a non-cash deduction that allows property investors to claim the natural wear and tear on their investment property over time. The Australian Taxation Office (ATO) recognises that buildings and assets decline in value as they age, and investors are entitled to claim depreciation deductions to reduce their taxable income each financial year.

Depreciation is generally calculated based on the cost and effective life of each depreciating asset. A qualified quantity surveyor prepares a tax depreciation schedule that outlines all the deductions you can claim, making the process easy for your accountant at tax time.

Why Depreciation Matters for Property Investors

Depreciation reduces your taxable income without requiring you to spend additional money. This means more cash in your pocket each year. For a typical residential investment property purchased for $400,000, depreciation deductions can be worth $5,000 to $12,000 in the first year — and even more for brand new properties that have been substantially renovated.

Many investors miss these valuable tax deductions simply because they do not have a tax depreciation schedule prepared. If you own a rental property and have not claimed depreciation, you could be missing out on significant tax deductions that reduce your rental property expenses and improve cash flow.

Division 40: Plant and Equipment Depreciation

Division 40 of the tax legislation covers plant and equipment assets — the removable or mechanical items inside your investment property. These are separate depreciating assets that decline in value over their effective life as determined by the ATO.

What Is Included in Division 40?

Plant and equipment assets generally include items like:

• Air conditioning units and air conditioners

• Carpets and blinds

• Ceiling fans and light fittings

• Ovens, cooktops, and kitchen appliances

• Hot water systems

• Furniture, fixtures, and fittings

• Garage door motors and lifts

Each plant item has an effective life assigned by the ATO. For example, a carpet has an effective life of 8 years, while an air conditioning unit is generally depreciated over 10 years.

How Division 40 Depreciation Is Calculated

There are two methods allowed for calculating plant and equipment depreciation:

• Diminishing value method — Provides higher deductions in the early years of ownership, calculated based on the remaining value of the asset.

• Prime cost method — Spreads the deduction evenly over the effective life, calculated based on the original cost.

For example, a $3,000 air conditioning unit with an effective life of 10 years would return approximately $600 in the first full financial year using the diminishing value method, compared to $300 per year using prime cost.

Division 40 Changes: Previous Owner and Second-Hand Assets

Since May 2017, investors who purchase a residential investment property can no longer claim depreciation on second-hand plant and equipment assets included by a previous owner. However, any new assets you install — such as new carpets, appliances, or air conditioners — are still eligible for depreciation claims.

Division 43: Capital Works Deductions

Division 43 covers capital works deductions — the structural elements and fixed items of the building itself. This is generally the largest deduction in any property depreciation schedule and applies to the construction costs of the building structure.

What Is Included in Division 43?

Capital works deductions cover the building structure and structural elements, including:

• Walls, floors, roofing, and windows

• Doors, built-in wardrobes, and extensions

• Plumbing, electrical wiring, and drainage

• Driveways, fencing, and retaining walls

• Common areas in unit complexes

• Renovations and improvements to the structure

How Division 43 Depreciation Is Calculated

Capital works deductions are calculated at 2.5% per year over 40 years for residential properties constructed after 15 September 1987. If construction costs are estimated at $250,000, the capital works deduction would be $6,250 per year. A qualified quantity surveyor can provide an accurate estimate of construction costs even for older properties.

Capital Works Deductions for Renovations

If you or a previous owner carried out renovations, those construction costs may qualify for capital works deductions under Division 43. Even older properties can produce significant depreciation deductions when renovations have been completed.

Division 40 vs Division 43: The Key Difference for Your Investment Property

Understanding the difference is essential for maximising your investment property depreciation:

Depreciation Report Examples: How Much Can You Claim?

The depreciation you can claim depends on factors including the age, value, and condition of your property.

Brand New Residential Investment Property — $500,000

A newly built residential property generally provides maximum deductions. With estimated construction costs of $320,000 and new plant and equipment assets worth $30,000, you could claim approximately $8,000 in capital works and $5,500 in plant items — a total of around $13,500 in depreciation deductions in the first year.

10-Year-Old Property — $400,000 Purchase Price

For older properties, capital works deductions are still available. With estimated construction costs of $200,000, you would claim $5,000 per year. Plant and equipment items you install — such as new carpets, blinds, or appliances — add to your deductions. Total first-year deductions could be $5,000 to $8,000.

Substantially Renovated Property — $450,000 Purchase Price

If $80,000 was spent on renovations, that adds $2,000 per year to your Division 43 claim. Combined with new plant items, first-year deductions of $9,000 to $11,000 are achievable.

Tax Depreciation Schedules: What You Need to Know

A residential tax depreciation schedule is a detailed report prepared by a qualified quantity surveyor that outlines every depreciation deduction available on your investment property. One tax depreciation schedule covers the lifetime of the property and the fee is fully tax deductible. Every rental property owner should have a property depreciation schedule to claim deductions they are entitled to.

Who Prepares a Tax Depreciation Schedule?

Tax depreciation schedules must be prepared by a qualified quantity surveyor who is a member of the Australian Institute of Quantity Surveyors. The ATO requires that construction costs be estimated by a recognised professional, ensuring the report is ATO compliant.

What Does a Depreciation Schedule Cost?

The depreciation schedule cost is generally $600 to $800 for a standard residential investment property and is fully tax deductible. The report can save thousands each year, making the return typically substantial.

Backdate and Claim Missed Deductions on Previous Returns

If you have missed depreciation deductions in previous years, the ATO allows you to amend your tax returns and claim missed deductions going back two financial years. Many investors find that amending previous returns provides a significant cash flow boost.

Property Depreciation Schedule for Older Properties

Many investors ask whether older properties qualify for depreciation claims. Division 40 deductions on second-hand assets are limited post-2017, but Division 43 capital works deductions are still allowed for any property constructed after September 1987. A qualified quantity surveyor can identify eligible items from renovations, saving thousands.

The Role of Quantity Surveyors

Quantity surveyors are recognized by the Australian Taxation Office (ATO) as the most suitable professionals to prepare tax depreciation schedules, ensuring compliance with tax legislation and maximizing deductions for property investors. The role of a quantity surveyor involves inspecting properties to identify all eligible assets for depreciation, applying the ATO's rules and forecasting assumptions to maximize tax deductions for property owners.

A tax depreciation schedule prepared by a quantity surveyor includes a detailed report that outlines the depreciation deductions available for the decline in value of a property and its assets over time. The one-off cost to prepare a depreciation schedule is typically between $600 and $900 and is itself 100% tax-deductible.

What a Tax Depreciation Schedule Covers

A tax depreciation schedule is a detailed report that outlines the deductions you can claim for the decline in value of your investment property and its assets, prepared by a qualified quantity surveyor. A tax depreciation schedule allows property investors to claim deductions for the decline in value of their property's assets, which can include the building structure and various fixtures and fittings. A tax depreciation schedule can last up to 40 years, allowing property investors to claim deductions for the wear and tear of their investment property over time.

Depreciation on Older and Second-Hand Properties

Depreciation tax deductions are available to residential property investors whose investment property was built after 15 September 1987, and renovations completed after this date can also be claimed. Investors can claim depreciation on renovations completed by previous owners, as the entitlement to claim depreciation on improvements transfers with the property.

Investors are generally unable to claim depreciation on second-hand plant and equipment items in residential properties purchased after 9 May 2017 unless the property is brand new or the assets are newly installed by the owner. This legislative change only affects Division 40 plant and equipment items in second-hand residential properties, not Division 43 capital works deductions.
