Commercial property owners often overlook thousands of dollars in deductions simply because they lack a professionally prepared depreciation schedule. A tax depreciation schedule identifies eligible assets and applies correct rates to ensure compliance with Australian Taxation Office guidelines. Even older buildings or previously owned properties can benefit from these reports. Missed deductions may be recoverable through amended tax returns where eligible. The applicable amendment period depends on the taxpayer’s circumstances and should be confirmed with a registered tax agent. The goal is always the same: identify and document every eligible deduction before tax time.
What Is Eligible for Depreciation?
Tax depreciation allows owners to claim deductions for the decline in value of a building and its assets over time. For commercial properties, this typically includes capital works under Division 43 and plant and equipment under Division 40. Division 43 covers structural elements such as foundations, walls, roofs, stairwells, fixed partitions and certain structural improvements. Division 40 covers depreciating assets like air conditioning, lighting, office furniture, mechanical services, electrical assets, lifts, security systems and office equipment. These deductions can reduce taxable income and improve cash flow.
Capital improvements made after the original construction, such as extensions, structural upgrades or major renovations, may also qualify for separate capital works deductions. Eligibility for the higher 4% capital works deduction rate depends on the nature of the building, construction commencement date and specific legislative requirements. Examples of properties that may qualify for the 4% rate include: eligible build-to-rent developments and certain short-term traveller accommodation, such as qualifying hotels, motels and similar accommodation premises, where the required conditions are satisfied.
Eligible depreciating assets, such as air conditioning units, carpet and office fittings, may generally be depreciated using one of two ATO-approved methods: the diminishing value method or the prime cost method. The diminishing value method calculates a higher yearly depreciation amount in the earlier years of an asset’s effective life, tapering off over time. The prime cost method spreads the deduction evenly across the asset’s effective life. The appropriate method depends on the asset, ownership circumstances and applicable tax rules. Choosing the right depreciation methods for your depreciating assets, and applying the depreciation rules correctly, can make a meaningful difference to the available depreciation deductions each year.
Who Can Claim Depreciation Deductions?
Depreciation is generally available where commercial property is used to produce assessable income. This includes investors purchasing property to generate rental income and owners leasing commercial space to tenants. Both groups can claim deductions on the building and its assets, provided the property is used for income-producing purposes. Commercial tenants may also be entitled to claim depreciation on fit-outs and equipment they installed themselves, depending on ownership and lease arrangements. Owners and tenants must each maintain their own schedule to avoid double-claiming the same assets.
The ATO recognises that a suitably qualified quantity surveyor can estimate construction expenditure where original records are unavailable. A professionally prepared tax depreciation schedule documents eligible Division 40 and Division 43 deductions and provides the supporting cost information relied upon by accountants when preparing income tax returns. Quantity surveyors apply construction cost knowledge, site inspection findings and industry cost data to assess eligible depreciation claims. This documentation is necessary for accurate returns.

Depreciation deductions reduce taxable income each year, but they interact with capital gains tax when the property is eventually sold. Capital works deductions claimed over the years of ownership generally reduce the property’s cost base, which affects the capital gain calculated at sale. The potential future CGT implications should be considered alongside the immediate tax benefits of claiming eligible depreciation deductions.
Commercial and residential property depreciation rules differ slightly. Retail, industrial and office buildings are assessed individually because construction costs and asset mixes vary widely. Residential investors may claim eligible capital works and depreciation deductions, but restrictions apply to certain second-hand residential property plant and equipment assets acquired after 9 May 2017 by individual investors. Real estate agents typically aren’t qualified to advise on depreciation rules, so owners should have each schedule reviewed separately by a qualified professional.
Owners holding both commercial and residential properties need separate schedules for each asset to ensure nothing falls through the cracks. The instant asset write-off threshold reverted to a statutory baseline of $1,000 for the 2026-27 financial year; applies to assets first used or installed from 1 July 2026. The instant asset write-off applies to eligible depreciating business assets, not the building structure itself. Eligibility and thresholds depend on the relevant income year, business turnover and when the asset was first used or installed ready for use.
Eligibility for Commercial Property Tax Depreciation
Eligibility for depreciation depends on several factors. Ownership requires that a person own the property or hold a leasehold interest. Income use means the property must be used to generate income, through rent or business operations. Construction dates affect whether capital works deductions are available and the applicable rate. Many eligible buildings constructed from 16 September 1987 may qualify for capital works deductions at 2.5%, subject to the property’s use, construction details and applicable legislation.
Asset types determine the number of items that can be claimed; properties with fit-outs, machinery, or equipment often have more claimable items. Even older buildings may qualify if renovations or upgrades have been made. If a person meets these criteria, a tax depreciation deduction can typically be claimed each year for the life of the schedule, whether they are a long-term owner, a commercial investor, or newer to leasing commercial property.
