In my 35 years working in the commercial fit-out industry, one of the most impactful financial moves I’ve seen businesses make is claiming depreciation on their fit-outs. Whether you’re a tenant or a property owner, claiming depreciation on the fit-out of an office space, café, or retail store is a smart way to reduce your taxable income and keep more cash in the business.
Many business owners are often unaware of just how much they can claim. If you’re not taking advantage of these deductions, you might be leaving money on the table that could be used better, reinvesting in your business or improving your cash flow for upcoming projects.
Depreciation For Office Fit-Outs
When discussing depreciation for office fit-outs, we’re essentially discussing the gradual decrease in value of the non-structural elements you’ve installed in your office space. This could include everything from the carpets and blinds to built-in cabinetry, air-conditioning systems, or partition walls.
For instance, I remember working on an office fit-out project in Perth, where the client upgraded their office partitions and added custom cabinetry. This wasn’t just about aesthetics; it was about improving the space’s functionality to maximise team productivity. And, of course, that fit-out qualified for significant depreciation deductions.
For tax purposes, the ATO allows businesses to depreciate these assets over their useful life, which means you can claim back part of the fit-out cost every year. Think of it as a way of getting value back for the wear and tear that happens over time as the office is used.

Benefits Of Claiming Tax Depreciation On Office Fit-Outs
I’ve seen firsthand how claiming depreciation can dramatically improve a business’s financial situation. Take, for example, a restaurant I worked with last year in Fremantle. They had done a complete fit-out, installing all-new kitchen equipment, flooring, and lighting.
They could reduce their taxable income by claiming depreciation, resulting in significant tax savings. This kind of saving can make a real difference for small businesses, helping them reinvest in their operations or improve cash flow during slower periods.
Beyond tax savings, claiming depreciation also allows you to allocate more funds to other business areas, whether marketing, new hires, or expanding operations. It’s an immediate way to boost your bottom line without dipping into your savings.
Here’s a quick breakdown of the benefits of claiming depreciation on your office fit-out:
- Reduction in Taxable Income
Depreciation allows you to lower your taxable income, which in turn reduces the amount of tax you pay each year. This is a great way to boost your business’s cash flow. - Improved Cash Flow
By claiming depreciation deductions annually, you keep more money in the business to reinvest or use for operational costs. - Long-Term Financial Planning
Depreciation deductions have been available for several years, providing long-term tax relief and the opportunity to spread financial benefits. - Increased Tax Savings
Over time, claiming depreciation can significantly add up, leading to substantial tax savings. - Better Business Planning
By understanding and claiming depreciation, you’re actively taking steps to manage your business’s finances more efficiently, making better decisions about reinvestment and cost-cutting.
ATO Depreciation Rates For Office Fit-Out: What You Need To Know
Understanding the ATO depreciation rates is crucial when claiming depreciation for your office fit-out. The ATO has clear guidelines on depreciating assets in your office fit-out, depending on whether they are part of the building structure or removable equipment. Knowing these rates will ensure you’re making the most of your deductions, allowing you to save on tax and improve your cash flow.
In my experience, business owners often overlook the distinction between Division 40 (plant and equipment) and Division 43 (capital works) depreciation rates. By understanding both categories and how to apply them, you can claim the maximum depreciation available for your office fit-out.
Division 43: Capital Works Allowance For Structural Elements
Division 43 is the category that covers the depreciation of a building’s structure and permanently affixed improvements. They fall under this category when you install fixtures that become part of the building itself, such as built-in cabinetry, flooring, and partition walls. Essentially, Division 43 applies to non-removable assets in the building.
One thing to note is that these deductions are typically spread over 40 years at a rate of 2.5% per year. This is the prime cost method applied by the ATO, meaning the deduction stays the same each year for the full 40 years.
What’s Covered Under Division 43?
When you’re looking to depreciate your office fit-out, keep in mind that Division 43 includes:
- Fixed partition walls: These are structural elements installed to divide up office space.
- Built-in cabinetry: This includes custom-made shelving, cupboards, or kitchen units installed in the office.
- Floors and ceilings: If you’ve installed new permanently affixed flooring (such as tiles or carpet) or ceilings as part of a refurbishment, these fall under Division 43.
- Plumbing and electrical work: Permanent electrical wiring, air-conditioning ducting, and plumbing fixtures like sinks or toilets installed as part of the fit-out.
- Leasehold improvements: Any alterations or improvements to the space that are permanently affixed and form part of the leased property
I worked on an office fit-out for a client in Melbourne who was upgrading their office space to accommodate more staff. They installed various built-in cabinetry and partition walls and upgraded the HVAC system (heating, ventilation, and air conditioning). These were considered Division 43 assets so that they could claim 2.5% of the total yearly cost for 40 years.
Accurately categorising the assets ensured they could benefit from long-term tax deductions.
Division 40: Depreciation For Plant And Equipment
Division 40 applies to removable assets not permanently affixed to the property. You can remove these items if you relocate or sell the business. They’re also often referred to as plant and equipment assets.
This category includes items like:
- Air conditioning units: These are typically considered plant and equipment, but their ducting (as part of the building’s structure) would fall under Division 43.
- Office furniture: Desks, chairs, filing cabinets, and workstations qualify for depreciation under Division 40.
- Lighting and security systems: If not permanently installed as part of the building, these assets are generally depreciated under Division 40.
- Computers and IT equipment: essential for most businesses and fall under Division 40.
The key difference between Division 40 and Division 43 is that Division 40 assets are depreciated based on their effective life, as determined by the ATO. Each asset type has a lifespan, and the depreciation rate is applied accordingly. The rates vary depending on the asset, so checking the ATO’s rulings for specifics is important.
How Division 40 Depreciation Works
- Depreciation Rate: For each type of asset, the ATO provides an effective life, which determines how long you can depreciate the asset and at what rate.
- Diminishing Value or Prime Cost: You can choose between two methods for depreciating plant and equipment—Diminishing Value or Prime Cost. The Diminishing Value method gives you larger upfront deductions, while the Prime Cost method provides equal deductions over the asset’s life.
A tech firm I worked with in Sydney installed several new computers, printers, and office furniture. Using Division 40 depreciation, they claimed depreciation on each asset over the ATO-specified effective life. For example, computers typically have an effective life of 4 years, which means the firm could claim 25% of the asset’s value per year (using the diminishing value method) or 12.5% per year using the prime cost method.
This allowed the firm to reduce its taxable income significantly, freeing up cash for expansion.
Examples of Assets Depreciated Under Division 40
| Asset Type | Effective Life | Depreciation Rate (Diminishing Value) | Depreciation Rate (Prime Cost) |
| Computers and IT Equipment | 4 years | 25% | 12.5% |
| Office Furniture (e.g. desks, chairs) | 10 years | 20% | 10% |
| Air Conditioning Units | 10 years | 20% | 10% |
| Security Systems | 5 years | 40% | 20% |

Methods For Calculating Depreciation On Office Fit-Out
Now that we’ve covered the basics of why and how to claim depreciation, let’s break down the methods of calculating it. There are two main methods used by the ATO for depreciating your office fit-out:
- Diminishing Value Method (Accelerated Depreciation)
This method allows you to claim higher depreciation in the early years of an asset’s life. However, the depreciation decreases over time as the asset’s value drops. - Prime Cost Method (Straight-Line Depreciation)
The prime cost method spreads the depreciation evenly over the asset’s effective life, allowing for consistent deductions year after year.
Comparison Of Depreciation Methods
| Depreciation Method | How It Works | Best For |
| Diminishing Value | Higher deductions in the early years | Businesses needing immediate tax relief |
| Prime Cost (Straight-Line) | Consistent depreciation over the asset’s life | Businesses prefer stable, long-term benefits |
Who Can Claim Depreciation On Office Fit-Outs?
Property Owners And Tenants: Who’s Eligible?
The ATO allows both commercial property owners and tenants to claim depreciation. If you’re a property owner, you can claim depreciation on both the building’s structure (Division 43) and any assets you own within the property (Division 40). This includes fixtures and fittings such as built-in cabinetry, air conditioners, and other essential business assets.
You can also claim tax depreciation for assets installed during your fit-out as a tenant. For instance, adding a new kitchen, installing air conditioning, or installing new lighting can depreciate over time. It’s important to note that if you’re a tenant and vacate the property without removing your fit-out, the property owner may be able to claim the remaining depreciation for those items.
I worked on a fit-out project for a tenant in Melbourne who installed new office partitions, furniture, and a full kitchen area for their staff. When they eventually vacated the property, we worked with the property owner to ensure that any remaining depreciation on the items was passed on. This prime example is how tenants and property owners can benefit from depreciation claims.
Special Depreciation Rules And Legislative Changes
As you investigate claiming depreciation for your office fit-out, you must know about special provisions that could affect your ability to maximise deductions. The Instant Asset Write-Off and Low-Value Pool are key schemes that substantially benefit businesses.
Instant Asset Write-Off For Small Businesses
For businesses with an annual turnover of less than $10 million, the Instant Asset Write-Off allows you to immediately claim the full cost of eligible assets, as long as they cost less than $20,000. This provision applies to assets purchased and installed ready for use between 1 July 2023 and 30 June 2025. After that, the limit drops to $1,000.
If you’re a small business owner, this is an absolute game-changer. Let me give you a real-world example: a client in regional Queensland needed to purchase new office furniture and a few high-tech computers to enhance their operations. Thanks to the Instant Asset Write-Off, they could claim the full deduction for these items in the year they were purchased. This reduced their taxable income significantly and helped them put the saved funds back into growing their business.
Eligibility Criteria:
- Annual Turnover: Must be under $10 million.
- Asset Limit: Eligible assets must cost less than $20,000.
- Claim Period: Applies to purchases made between 1 July 2023 and 30 June 2025.
- After 30 June 2025, the threshold reverts to $1,000.
Low-Value Pool For Accelerated Deductions
If you have assets that cost less than $1,000 and have been depreciated using the Diminishing Value method, you can place them into a Low-Value Pool. These assets are then depreciated at an accelerated rate of 37.5% annually. This can significantly accelerate your deductions, which is perfect if you have a lot of smaller assets, like office equipment or furniture.
For example, a client in Sydney outfitted their office with multiple low-cost desks and chairs, all under the $1,000 threshold. By adding these to the Low-Value Pool, they could claim faster depreciation, which translated to larger deductions in the early years of their asset’s life.
Key Points About the Low-Value Pool:
- Eligibility: Assets with a written-down value of less than $1,000.
- Depreciation Rate: Accelerated rate of 37.5% per year for existing pool assets.
- New Assets: The first-year deduction is 18.75% for newly acquired low-value assets.
Residential Property Changes (Post-May 2017)
While these changes won’t directly affect commercial properties, it’s worth noting that the ATO introduced new rules for residential properties post-May 2017. The changes mostly affect how depreciation can be claimed for residential properties’ second-hand plant and equipment items. However, this does not impact commercial properties. So, if you’re working with a commercial fit-out or a residential property used for business purposes (like a hotel), these changes won’t apply to you.
The Role Of A Quantity Surveyor In Maximising Your Depreciation Deductions
Engaging a qualified quantity surveyor (QS) can be a real game-changer when claiming depreciation for office fit-outs. From personal experience, I’ve seen how businesses, especially those undertaking significant fit-out projects, can make the most of their deductions by leveraging the expertise of a QS. Here’s why their involvement is crucial.
Expertise And Accuracy
Quantity surveyors are not just professionals with experience in construction costs – the ATO also recognises them as qualified professionals for estimating depreciation on commercial properties. This is particularly important when the actual costs of the fit-out aren’t readily available, such as when purchasing an existing business with a fit-out already in place.
They’ll provide a clear, accurate assessment of the fit-out value, ensuring that you claim the maximum depreciation possible for Division 40 (plant and equipment) and Division 43 (capital works allowance) assets. The ATO also recognises them.
Depreciation Schedule: What’s Included?
When you engage a QS, they’ll prepare a tax depreciation schedule. This schedule is a comprehensive report that identifies all the depreciable assets in your fit-out and assigns them an effective life as determined by the ATO. This is crucial for ensuring you’re not missing out on any potential deductions.
For example, when I worked with a retail client who installed an extensive range of refrigerated display units, the QS ensured that each piece of equipment was properly itemised, with depreciation applied to the correct rates. This included calculating the effective life of the refrigeration system, ensuring the client received the maximum allowable depreciation each year.
Maximising Deductions With A Quantity Surveyor
A QS doesn’t just ensure compliance with ATO guidelines; they actively help businesses maximise their depreciation deductions. By using their expertise, you can ensure that:
- All eligible assets are identified – This includes small but often overlooked items like light fittings, air conditioning units, and office furniture.
- The correct depreciation rates are applied – For assets with varying effective lives, a QS will apply the correct depreciation rate as per ATO rulings, ensuring you’re not leaving money on the table.
- Past missed claims can be recovered – If you haven’t claimed depreciation in previous years, a QS can help you recover missed claims, often up to two years for individuals and four years for trusts or entities.
In one case, a restaurant in Adelaide installed new kitchen equipment but failed to claim depreciation in the first year. With the help of a QS, they could recover the missed depreciation for the prior year and start claiming it correctly for the ongoing years.
Cost-Effective For Long-Term Savings
Interestingly, the fee you pay a quantity surveyor for preparing your depreciation schedule is 100% tax-deductible in the year it’s purchased. So, while there’s an upfront cost, the return on investment regarding the additional depreciation you can claim often far outweighs this expense.
If you’re undertaking a large fit-out project, the savings a QS can unlock are typically much greater than the cost of their services. This is especially true for larger commercial properties where the complexity of the fit-out and depreciation calculations increases.
Benefits of Engaging a Quantity Surveyor
| Benefit | How It Helps Your Depreciation Claim |
| Maximised Deductions | Identifies all eligible depreciable assets and ensures correct depreciation rates. |
| ATO Compliance | Ensures your depreciation claims are in line with ATO guidelines and rulings. |
| Recovery of Missed Claims | Helps recover missed depreciation claims for up to 2-4 years. |
| Tax-Deductible Fees | The QS fee is tax-deductible, making it a cost-effective investment. |
Claiming depreciation on your office fit-out is an excellent way to reduce your taxable income, improve cash flow, and maximise your business’s tax savings. Whether you’re a tenant or a property owner, taking the time to understand the ATO’s depreciation guidelines and engaging a quantity surveyor to create a detailed depreciation schedule will help ensure that you’re claiming every eligible deduction. By following these steps, you can free up resources for reinvestment, improve your business’s financial health, and make the most of your commercial property fit-out.
