The Ultimate Guide to Commercial Property Depreciation in Australia

 

1. What is commercial property depreciation?

Commercial property depreciation is the tax deduction available for the ownership and ageing of commercial buildings, fit-outs, equipment, and improvements.

Building owners, tenants, and business operators can all be eligible to claim for depreciation of a building and/or it’s associated assets. 

In short, depreciation allows you to recover (over time) the cost of the assets you’ve already paid for — improving cash flow and reducing taxable income annually. 

Capital Claims Tax Depreciation are quantity surveyors, depreciation specialists and registered tax agents with extensive experience assessing and reporting on depreciation for commercial investors and business operators.

2. Who can claim commercial property depreciation?

Anyone who owns, leases, or operates a business from a commercial property can be eligible to claim depreciation. 

This includes: 

• commercial landlords 
• business owners 
• commercial tenants 
• franchise operators 
• medical and allied health practice owners 
• hospitality venue owners and operators 
• manufacturing plant owners and operators 
• retail owners and operators 
• professional services firms 

If you’ve paid for a building, a fit-out, equipment, or improvements, you’re entitled to claim depreciation. 

Capital Claims works closely with both building owners and tenants to ensure all improvements, fit-outs, and equipment are identified, accurately assessed and reported.

3. Why does depreciation matter for both investors and business owners?

Depreciation improves cash flow by reducing taxable income without requiring ongoing spending. 

For commercial property investors: 

• reduces taxable income 
• increases cash flow 
• supports strategic investment 

For commercial tenants: 

• offsets fit-out and equipment expenses 
• reduces taxable profit as a paper deduction 
• helps to recover the cost of leasehold improvements 

Capital Claims has helped thousands of commercial landlords and tenants transform underclaimed assets into meaningful tax savings through accurate, industry specific depreciation schedules.

4. What are Division 40 and Division 43, and why do they matter?

Division 40 and Division 43 are the two key pieces of ATO legislation that define how commercial property depreciation must be calculated.

They determine which assets qualify, how they must be categorised, and the rate at which they can be depreciated. 

Division 43 — Capital Works (Building Structure) 

This covers the fixed, structural elements of a building, such as walls, floors, ceilings, concrete slabs, and structural improvements. These structural assets typically depreciate at 2.5% per year over 40 years – though this will occasionally vary based on building use. 

Division 40 — Plant & Equipment (Removable or Mechanical Assets) 

This covers the mechanical, electrical, and removable items inside a commercial property — these assets typically wear out faster and have individual ATO assigned effective lives. 

Why accurate categorisation is essential 

Correctly separating Division 40 and Division 43 assets is critical step in preparing a depreciation schedule. Misclassification can lead to: 

• underclaiming deductions 
• overclaiming deductions (audit risk) 
• incorrect effective life calculations 
• missed opportunities for accelerated depreciation 
• noncompliance with ATO requirements 

This is why the ATO requires that only qualified professionals — such as quantity surveyors — estimate construction costs and assign asset classifications. 

Capital Claims’ team specialises in this exact process, ensuring every asset is identified in the correct legislative category so your deductions are maximised and your schedule remains fully ATO compliant.

5. What does Division 43 (Capital Works) include?

Division 43 includes the structural, fixed, and nonremovable elements of a commercial building. 

Examples: 

• walls, floors, ceilings 
• concrete slabs 
• structural partitions 
• mezzanine floors 
• car parks and loading docks 
• retaining walls 
• built-in joinery (though categorisation for this can vary based on industry type and use 
• structural upgrades and renovations 

Our team has decades of experience analysing commercial building structures and improvements, allowing us to accurately separate capital works from plant and equipment to maximise deductions.

6. What does Division 40 (Plant & Equipment) include?

Division 40 includes mechanical, electrical, and removable assets — the items inside a commercial property that tend to be more industry specific and wear out faster than the building itself. 

Examples of Division 40 assets: 

• air conditioning systems 
• lighting and electrical components 
• security and access systems 
• commercial kitchen equipment 
• medical and diagnostic equipment 
• manufacturing machinery 
• lifts, pumps, motors, and mechanical systems 
• IT, AV, and communications equipment 
• furniture and soft furnishings 

Capital Claims’ quantity surveyors specialise in identifying and valuing every eligible plant and equipment asset and have extensive experience across all sectors – hospitality, professional services, industrial and manufacturing, retail, health and fitness and warehousing.

7. How is the effective life of an asset determined?

The ATO sets the effective life of each new asset, and it must be reassessed when an asset changes hands or changes use. 

This means the effective life is reassessed: 

• when a property is sold 
• when a new tenant takes over 
• when the use of a property changes (e.g., warehouse → retail) 

Capital Claims are experts in reassessing asset life based on condition, use, and ownership changes — a level of detail that ensures your deductions are both maximised and audit ready.

8. What fit-out items can owners and tenants claim?

Fit-outs are often the largest source of depreciation deductions for both commercial property owners and tenants. 

Owners can claim: 

• building upgrades and additions (capital works) 
• landlord funded fit-outs 
• building integrated services 

Tenants can claim: 

• fit-outs they paid for 
• their leasehold improvements 
• their equipment 
• assets they abandon or dispose of at the end of the tenancy 

Fit-outs often contain a high concentration of Division 40 assets, which depreciate faster and deliver larger early year deductions. 

Capital Claims is highly experienced in separating landlord works from tenant funded improvements, valuing complex fit-outs, and identifying abandoned assets — ensuring both owners and tenants claim every deduction they’re entitled to.

9. What assets can be claimed across different business types?

Different commercial property types contain different asset mixes, and each industry has unique depreciation opportunities. 

Understanding your business type helps identify the highest value deductions.

10. How is commercial depreciation calculated?

Depreciation is calculated using either the Prime Cost or Diminishing Value method. 

Prime Cost 

• applicable for both Division 43 and Division 40 assets 
• even deductions claimed annually over the asset’s life 

Diminishing Value 

• applicable for Division 40 assets only 
• takes advantage of low-value pooling for accelerating deductions 
• greater deductions claimable in earlier years 

The method most appropriate for your circumstances should be discussed with your accountant. Once a method is chosen for Division 40 assets, that method must be used every year for the remaining effective lives of the assets. 

Every Capital Claims schedule includes both methods of depreciation with graphed results for the full life of the report, giving you the flexibility to choose the approach that best suits your tax strategy.

11. What special depreciation rules apply to commercial properties?

Commercial properties benefit from several accelerated deduction opportunities. 

Low Value/Cost Pooling 

Assets under $1,000 can be pooled for faster depreciation. 

Instant Asset Write-Offs 

Available to eligible small businesses (thresholds vary by year). 

Residual Value Write-Offs 

If you remove or dispose of an asset, you can claim its full remaining value in the financial year it was disposed of. 

When clients renovate or replace assets, Capital Claims conducts detailed disposal assessments to ensure any removed items are accurately reported for write-off — unlocking deductions that are often missed without specialist support.

12. When should you order a commercial depreciation schedule?

You should order a schedule as soon as you purchase, and then in preparation for and after renovations, because each moment creates new deductions or changes the way assets must be valued.

Here’s why each timing matters:

Immediately after purchase

Ordering a schedule right after settlement ensures all assets are valued at the correct point in time. This captures the full opening value of both Division 40 and Division 43 assets and prevents missed deductions across your years of ownership.

Capital Claims regularly prepares schedules for newly purchased properties to ensure owners maximise claims straight away.

Before renovations or fit-outs 

Any renovation, upgrade, or fit-out introduces new depreciable assets — and may also trigger residual value write-offs for assets you’ve removed. If you’re about to renovate and don’t already have a Capital Claims Tax Depreciation schedule then a pre-renovation assessment will ensure that all existing assets are captured and valued for the purposes of write-off.  

After renovations or fit-outs 

A post-renovation assessment will ensure all new capital works and assets are identified and reported for maximum depreciation deductions. 

Before vacating a leased property 

Tenants often leave behind assets they paid for. These “abandoned assets” can usually be written off immediately, delivering significant deductions in the final year of tenancy. 

We help tenants who don’t already have a Capital Claims Tax Depreciation Schedule to identify and value these items so they don’t miss out on end of lease deductions. 

13. What’s included in a Capital Claims depreciation schedule? 

A Capital Claims schedule includes everything required for full ATO compliance and maximum deductions. 

• site inspection 
• asset identification 
• division 40 + 43 breakdown 
• annual deduction forecast 
• ATO compliant documentation 
• audit ready reporting 

Every schedule is built from the ground up by experienced professionals who understand commercial property inside out — delivering accurate, optimum and ATO-compliant results.

14. How much does a commercial depreciation schedule cost?

The range of different commercial properties in Australia is extensive, from small warehouses to large multi-tenant industrial, hospitality, retail, medical and professional complexes. Fees for commercial depreciation schedules reflect this range of complexity and the scope of work required and are quoted on a per job basis. 

In every case the return on investment for a depreciation is exceptional.  

15. What mistakes cause commercial owners and tenants to miss deductions?

The most common mistakes include: 

• not claiming abandoned assets 
• tenants not claiming fit-outs 
• assuming older buildings don’t qualify 
• using accountants instead of QS for valuations 
• not updating schedules after renovations 

Capital Claims helps clients avoid these pitfalls by providing clear guidance and comprehensive, audit ready reporting.
