When you own an investment property in Australia, you can claim deductions for the wear and tear on the building and its assets. This is known as tax depreciation. The Australian Taxation Office (ATO) splits these deductions into two main categories: Division 40 for plant and equipment, and Division 43 for capital works. Understanding the difference between division 40 and 43 is important if you want to get the most out of your tax return. It can seem a bit confusing at first, but breaking it down makes it much clearer. Let’s take a look at what each one covers.
Division 40 and 43: Understanding Tax Depreciation Categories

When you own an investment property in Australia, you can claim deductions for the wear and tear on both the building itself and the items within it. The Australian Taxation Office (ATO) splits these deductions into two main categories: Division 40 and Division 43. Getting a handle on these is important if you want to get the most out of your tax return.
Think of it this way: Division 40 covers the things you can generally pick up and move, or that get replaced more often. These are often called ‘plant and equipment’. Division 43, on the other hand, deals with the actual bones of the building – the structural stuff that’s fixed in place.
Understanding the difference between these two divisions is key to maximising your property investment’s tax benefits.
Here’s a quick look at what each covers:
- Division 40 (Plant and Equipment): This includes items like air conditioners, hot water systems, ovens, dishwashers, carpets, blinds, and security systems. The ATO assigns an ‘effective life’ to each of these, which dictates how quickly you can claim their depreciation. You can use different methods to calculate this, like the diminishing value or prime cost methods.
- Division 43 (Capital Works): This covers the construction costs of the building itself and any permanent fixtures. Think bricks, concrete, roofing, windows, and even things like fences or retaining walls. Generally, you can claim 2.5% of these costs each year for up to 40 years, depending on when the construction started.
It can get a bit confusing, especially when renovations come into play, as they can often involve both divisions.
Properly claiming these deductions means you’re essentially getting a tax refund for the costs associated with the wear and tear of your investment property. It’s a way the government encourages investment in housing.
To make sure you’re claiming everything correctly, it’s usually best to get a depreciation schedule prepared by a qualified quantity surveyor. They can help identify all eligible assets and construction costs, ensuring you don’t miss out on valuable deductions.
Division 40 Explained: Depreciating Plant and Equipment Assets

When we talk about investment properties, Division 40 of the tax law is all about the things you can take out of the place without causing damage. Think of it as the stuff that wears out faster or can be swapped out. The Australian Taxation Office (ATO) calls these ‘plant and equipment’ assets. This covers a massive range of items, from the carpets on the floor and the blinds on the windows to the hot water system, air conditioners, ovens, and even smoke alarms. Basically, if it’s a fixture or fitting that’s not part of the building’s structure itself, it likely falls under Division 40.
Each of these items has an ‘effective life’ determined by the ATO. This is how long the tax office reckons the item will be useful for. Based on this effective life, you can claim a deduction for the asset’s cost over time. There are two main ways to calculate this deduction:
- Diminishing Value Method: This method lets you claim a larger portion of the asset’s cost in the earlier years. It’s like saying the item loses more of its value right at the start. So, you get a bigger tax break sooner.
- Prime Cost Method: This is a straight-line approach. You claim the same amount of deduction each year over the asset’s effective life. It’s a more even spread of the deduction.
The choice between these methods can significantly impact your cash flow, especially in the first few years of owning an investment property.
It’s important to note that for residential properties bought after May 9, 2017, you generally can’t claim depreciation on second-hand plant and equipment. However, if you buy a brand-new property, do a major renovation, or purchase commercial property, these rules might not apply in the same way. Getting a depreciation schedule prepared by a qualified quantity surveyor is the best way to make sure you’re claiming everything you’re entitled to under Division 40.
Keeping track of all these individual assets and their depreciation can feel a bit much, but it’s where the real tax savings often hide. Don’t just assume you know what you can claim; a proper schedule makes all the difference.
Division 43 Explained: Claiming Capital Works Deductions
Division 43, often referred to as Capital Works Deductions, is all about claiming tax deductions for the actual construction costs and structural improvements made to an income-producing property. Think of it as claiming the wear and tear on the building itself – the bricks, mortar, and fixed elements that form the structure. This is different from plant and equipment, which we’ll cover under Division 40.
These deductions are generally calculated as a percentage of the original construction cost, spread over a period of up to 40 years. For most residential properties built after 15 September 1987, this rate is typically 2.5% per year. Commercial properties might have different dates and rates, so it’s worth checking the specifics for your situation.
Here’s a breakdown of what typically qualifies:
- Construction Costs: The original cost of building the property, including labour and materials.
- Renovations and Improvements: Significant upgrades or structural changes made to the property, like adding a new bathroom, extending a room, or replacing the roof.
- Fixed Assets: Items that are permanently fixed to the property, such as internal walls, tiling, plumbing, and electrical wiring.
It’s important to note that you can’t claim the land value or items that are considered plant and equipment (like ovens, carpets, or blinds) under Division 43. Those fall under Division 40.
The key to claiming Division 43 deductions is understanding the construction start date and the original construction cost. If you didn’t build the property yourself, a qualified quantity surveyor can estimate these costs, ensuring you claim accurately and compliantly with the Australian Taxation Office.
Even if your property was built before the eligibility dates, you might still be able to claim deductions for renovations or extensions completed after those dates. This means that even older properties can offer significant tax benefits through structural upgrades. For example, if you undertake a major renovation, the cost of that renovation can be claimed under Division 43, similar to the original construction. This can lead to substantial tax savings over the life of the improvement, potentially reducing your taxable income each year. It’s a good idea to get a depreciation schedule from a professional to make sure you’re getting everything you’re entitled to for your investment property.
| Item Category | Division 43 Claimable? |
Notes |
| Walls, Floors, Roofs | Yes | Structural components of the building. |
| Driveways, Fencing | Yes | Permanent external structures. |
| Plumbing, Wiring | Yes | Fixed internal systems. |
| Ovens, Carpets | No | These are plant and equipment (Division 40). |
| Land Value | No | Land is not a depreciable asset. |
Key Differences Between the Division 40 and 43
Alright, let’s get down to brass tacks. When you’re looking at your investment property and trying to figure out what tax deductions you can actually claim, you’ll bump into Division 40 and 43 of the Australian tax law. They sound a bit similar, but they cover pretty different things, and knowing the difference is key to not missing out on money you’re owed.
Basically, Division 40 is all about the ‘plant and equipment’ in your property. Think of things that are easily removable or mechanical. This includes stuff like your air conditioner, the hot water system, blinds, ovens, dishwashers, and even light fittings. The Australian Taxation Office (ATO) gives these items an ‘effective life’, and you claim depreciation based on that. It’s a bit like saying, ‘this oven will last 10 years, so I’ll claim a bit of its cost each year’.
Division 43, on the other hand, is for the ‘capital works’ – the actual structure of the building itself. This is the stuff that’s fixed and would be damaged if you tried to remove it. We’re talking about bricks, concrete floors, roofing, windows, fences, driveways – the bones of the place. For these, you can generally claim 2.5% of the construction costs each year, for up to 40 years, provided the building was constructed after certain dates (usually after September 15, 1987, for residential properties).
So, the big difference is what they cover: removable items versus the building’s structure. It’s like comparing the furniture inside a house to the house itself.
Here’s a quick rundown:
- Division 40: Plant and Equipment (removable items like appliances, carpets, air conditioners).
- Division 43: Capital Works (structural components like walls, roofs, concrete slabs, driveways).
| Aspect | Division 40 (Plant & Equipment) | Division 43 (Capital Works) |
| What it covers | Removable assets, mechanical items, fixtures, and fittings. | Structural elements of the building and fixed assets. |
| Claiming Rate | Based on the ATO-determined effective life of each asset. | Generally, 2.5% per year over 40 years (for eligible buildings). |
| Examples | Ovens, dishwashers, air conditioners, carpets, light fittings. | Walls, roofs, concrete floors, driveways, tiling, fences. |
It’s important to remember that for properties bought after May 9, 2017, you generally can’t claim depreciation on second-hand plant and equipment (Division 40) unless you’re buying them through a business. However, Division 43 claims for the building’s structure are usually unaffected by this rule.
When you renovate, it can get a bit more interesting. New structural improvements you make might fall under Division 43, meaning you can claim 2.5% on those costs too. And if you replace something like an old kitchen, the old components might be written off, and the new ones can be depreciated under the relevant division. It really pays to get a professional to look at your specific situation.
Depreciation Methods: Diminishing Value vs. Prime Cost

When you’re claiming depreciation on plant and equipment assets under Division 40, you’ve got two main ways to go about it: the diminishing value method and the prime cost method. It’s not a one-size-fits-all situation, and picking the right one can make a difference to your cash flow, especially in the early years of owning an investment property.
First up, there’s the diminishing value method. Think of it like this: an asset loses more of its value when it’s new, and then less as it gets older. So, this method lets you claim a bigger chunk of depreciation in the earlier years of the asset’s life, and then smaller amounts as time goes on. It’s a bit like a sliding scale. For example, if you bought an asset for $1,000 with a five-year effective life, you might get a deduction of $400 in the first year, then maybe $240 in the second, and so on. This can be pretty handy if you’re looking to boost your tax deductions early on.
On the other hand, we have the prime cost method, sometimes called the straight-line method. This one’s a bit more straightforward. It spreads the cost of the asset evenly over its entire effective life. So, using that same $1,000 asset with a five-year life, you’d claim $200 each year for five years. It’s predictable and gives you a consistent deduction amount year after year. This might suit investors who prefer a steady, predictable tax outcome rather than a big hit upfront.
Here’s a quick rundown:
- Diminishing Value: Higher deductions in the early years, lower in later years. Good for improving early cash flow.
- Prime Cost: Equal deductions each year over the asset’s effective life. Offers consistent tax benefits.
It’s important to remember that once you choose a method for a particular asset, you’re generally stuck with it for that asset’s life. You need to make this choice when you lodge your first tax return for the property. So, it’s worth giving it some thought.
The choice between these two methods isn’t just about numbers; it’s about aligning your tax deductions with your overall investment strategy and when you anticipate needing those tax benefits the most. Consider your cash flow needs and long-term financial planning when making this decision.
Impact of Renovations on Division 40 and 43 Claims
When you start thinking about renovating an investment property, it’s not just about making it look nicer or more functional. It can actually have a pretty big impact on your tax return, especially when it comes to depreciation. Both Division 40 and Division 43 can be affected, so it’s worth getting your head around it.
Basically, any structural work you do as part of a renovation – like adding a new bathroom, putting in a new kitchen, or even just replacing the roof – is generally treated as new construction. This means these costs can be claimed under Division 43, usually at a rate of 2.5% per year for up to 40 years from when the renovation was finished. It’s important to remember that you need the actual cost of the renovation for this. If you don’t have records, a quantity surveyor can help estimate these costs for you.
Here’s a quick rundown of how renovations fit in:
- New Capital Works: Structural improvements from renovations become new capital works. Think walls, floors, and fixed plumbing.
- Plant and Equipment: Non-structural items installed during renovations, like ovens, blinds, or air conditioners, fall under Division 40. These have different effective lives and depreciation methods.
- Demolished Assets: If you remove old parts of the building during renovation, the remaining undeducted value of those old parts might be claimable as an immediate write-off. This is a bit more complex and requires good record-keeping.
It’s not just about the new stuff you add; what you take away can also have tax implications. Understanding the original cost and how much depreciation you’ve already claimed on demolished elements is key to maximising these deductions.
For example, if you spend $30,000 on a new kitchen renovation, you could potentially claim $750 each year (2.5% of $30,000) under Division 43 for 40 years. If the renovation also included a new oven and dishwasher, these would be claimed separately under Division 40 based on their individual effective lives. It’s a good idea to get a depreciation schedule prepared by a professional to make sure you’re claiming everything you’re entitled to, especially after renovations. This helps clarify the distinctions between capital works and plant and equipment depreciation.
So, while renovations are great for property value, they also offer a chance to boost your tax deductions. Just make sure you keep good records of all expenses and consider getting expert advice to navigate the rules correctly.
Legislative Changes Affecting Division 40 and 43 Deductions
The tax laws around depreciation and capital works deductions aren’t static; they get tweaked now and then. Keeping up with these changes is important if you want to make sure you’re claiming everything you’re entitled to. For instance, there have been adjustments to what counts as a capital works deduction and how certain assets are treated under Division 40.
It’s vital to stay informed about any updates from the Australian Taxation Office (ATO) as these can directly impact your ability to claim deductions.
Here are a few areas where changes have occurred or are worth noting:
- Temporary Full Expensing: While this was a significant measure allowing businesses to immediately deduct the cost of eligible depreciating assets, its availability has changed. It’s important to check the current rules regarding its application and any sunsetting dates.
- Changes to Effective Life Estimates: The ATO periodically reviews and updates the effective life estimates for various assets. This can alter the depreciation rate you can claim under Division 40 for new assets or assets acquired after a specific date.
- Impact on Renovations: Specific rules can apply to renovations, especially concerning when the work was completed and whether it qualifies as capital works. For example, renovations completed after certain dates might have different deduction rates or eligibility criteria.
The landscape of tax legislation is always shifting. What was permissible last year might have different conditions this year. Therefore, a proactive approach to understanding these legislative shifts is key to optimising your investment property deductions.
It’s not just about knowing the rules as they are today, but also anticipating how they might evolve. This means keeping an eye on government announcements and ATO guidance. For example, if you’re planning significant renovations or acquiring new assets, understanding the current legislative framework is essential before you spend the money.
Maximising Tax Benefits: Strategies for Division 40 and 43
Getting the most out of your property investments often comes down to smart tax planning, and that’s where understanding Division 40 and 43 helps. It’s not just about knowing what you can claim, but how you claim it to get the best results.
One of the simplest ways to boost your deductions is to make sure you’re claiming everything you’re entitled to. For Division 40 assets, remember that items costing $300 or less can be written off immediately. Also, assets with a written-down value under $1,000 can be grouped into a low-value pool, attracting a 37.5% depreciation rate. This can make a surprising difference to your taxable income.
When it comes to renovations, think about how they interact with both divisions. New structural elements from renovations can be claimed under Division 43 at 2.5% per year for up to 40 years. Plus, any old fixtures you remove might have a residual value that can be written off. It’s a double win if you plan it right.
Here are a few strategies to consider:
- Get a Depreciation Schedule: This is probably the most important step. A qualified quantity surveyor can identify all eligible assets and structural components, estimate their costs (even for older properties), and prepare a compliant schedule. This ensures you don’t miss out on any deductions and stay on the ATO’s good side. You can find professionals who help with your Depreciation Schedule Australia.
- Choose the Right Depreciation Method: For Division 40 assets, you can choose between the diminishing value method (higher deductions early on) and the prime cost method (consistent deductions). Your choice can impact your cash flow, so consider your investment goals.
- Track All Expenses: Keep meticulous records of all purchases and renovation costs. This includes things like architect fees and permits, which can often be included in your capital works calculations.
- Consider the Low-Value Pool: If you have multiple low-value assets, pooling them can simplify your claims and accelerate deductions.
Making informed decisions about depreciation can significantly improve your investment’s financial performance. It’s about being proactive and ensuring your tax claims accurately reflect the wear and tear on your property and its assets.
Don’t forget that for properties bought after May 9, 2017, you generally can’t claim depreciation on second-hand Division 40 items unless it’s a business purchase. However, Division 43 claims for structural works are usually unaffected by this rule. Staying up-to-date with these changes is key to maximising your benefits.
Frequently Asked Questions
What’s the main difference between Division 40 and Division 43 for my investment property?
Think of it this way: Division 40 covers the ‘bits and pieces’ you can often remove or replace easily, like ovens, air conditioners, or blinds. Division 43 is for the building’s actual structure – the walls, floors, and roof – and things permanently fixed to them.
Can I claim deductions for renovations under these rules?
Yes, absolutely! Renovations usually fall under Division 43 as they often involve structural improvements or permanently fixed items. It’s like building new parts of the property, so you can claim deductions over time for these costs.
How do I figure out how much I can claim for Division 43 (Capital Works)?
For most new homes built after mid-1987, you can generally claim 2.5% of the original building cost each year for up to 40 years. If you don’t know the exact cost, a special surveyor can estimate it for you.
What happens if I buy an older investment property with existing fixtures?
For Division 40 (plant and equipment), if you buy a residential property after May 9, 2017, you generally can’t claim deductions on existing second-hand items unless you’re buying it as a business. However, Division 43 claims for the building’s structure are usually still allowed.
Are there different ways to calculate depreciation for Division 40 items?
Yes, there are two main ways. The ‘Diminishing Value’ method lets you claim more in the early years, which can be good for your cash flow. The ‘Prime Cost’ method spreads the claim evenly over the item’s life, giving you a consistent deduction each year.
Do I need a special report to claim these deductions?
It’s highly recommended. A qualified quantity surveyor can prepare a depreciation schedule that details all your eligible Division 40 and 43 claims. This ensures you’re claiming accurately and getting the most out of your tax benefits, following the Australian Taxation Office’s rules.
