What is capital works deductions?
Section 43 references the relevant section of the tax legislation, Income Tax Assessment Act, 1937. The Australian Taxation Office refers to it as the “Capital Works Deduction” or “Building Write-Off”.
This section allows you to claim a deduction against your income for the wear and tear of these structural items as well as the items that are considered to be fixed items to the property. These deductions included any structural improvements that have been made to the property.
In the property tax depreciation schedule world, deductions are exactly what you are aiming for because they are expenses that reduce your taxable income, which means fewer taxes and more money in your pocket.

How Much Can I Claim?
Depending on the type of expense, the date of construction, and the cost of the building or construction cost, you can claim a Division 43 depreciation at a rate of 2.5% to 4%. Generally, for building work after 15 September 1987, you claim a capital works deduction at a rate of 2.5% over 40 years.
Remember, the land itself is not eligible for write-off. The cost of acquiring the land or demolishing existing structures isn’t deductible.
The amount you can claim also depends on the cost of construction. If you forgot the construction costs or have lost your paperwork, you need to get an estimate from a quantity surveyor.

How Are Capital Works Deductions Calculated?
Capital work deductions are calculated according to the percentage rate at which a building depreciates. This rate is determined by the date at which construction commenced and the intended use of the building (i.e., commercial or residential purposes).
If you’re a property investor who owns residential properties built after September 15, 1987, you can claim a capital works deduction at a rate of 2.5% per year over 40 years.
However, if any structural improvements were made to residential properties after February 27, 1992, you would then have to claim capital works deductions on the actual construction costs at a rate of 2.5% per year for 40 years from the date of construction completion.
As for a commercial rental property, the rate of capital works deduction can be either 2.5% or 4% per year. It all depends on when construction commenced, the type of capital works, and their intended use.
Does Capital Works Allowance Division 43 Apply to Any Building Work?
Division 43 applies to buildings and structural improvements, only on income-producing properties and only when producing income.
For example, if you rent your property for six months out of the year, you will only be able to deduct 50% of the cost of the capital works or Division 43 depreciation. The calculation is based on the number of days your property was rented out.
The capital works deduction is available for
- buildings, alterations, or improvements to a building, such as a kitchen or bathroom upgrades
- alterations or modifications to a leased building,
- building extensions such as garages, entertainment decks, showrooms, and offices
- structural enhancements such as sealed driveways, fences, and retaining walls
- earthworks for environmental protection, such as embankments
- Initial expenses, including architect or engineering fees, surveying fees, and costs of building permits, also form part of the construction expenditure.
Remember, you can only start claiming this deduction once the renovation is complete.

What is the difference between Division 43 and Division 40 Allowances?
Division 40 is quite similar to Division 43, hence all the confusion. You need to know that Division 40 depreciates faster and applies to particular items.
Division 40 is also known as “Plant and Equipment”. Some examples of items Division 40 applies to include:
- ceiling fans
- air conditioning units
- smoke alarms
- solar panels
- indoor or outdoor furniture
- bathroom exhaust fans
- Division 40 applies at a rate of 20% over ten years.
Division 43 is known as The Capital Works Allowance and relates to the structure of the building and refers to items like concrete, brickwork and tiling.
- Buildings, alterations, or improvements to a building
- Garages, entertainment decks, showrooms, and offices
- Sealed driveways, fences, and retaining walls
- Earthworks for environmental protection, such as embankments
- Architect or engineering fees, surveying fees, and costs of building permits.
Determining Division 40 or 43 can be confusing, especially for particular assets. One of many examples is if you are constructing a pool in your rented residential property. Construction of the pool itself would fall under Division 43, but the pumps for the pool would be under Division 40.
If these assets are not classified correctly, you can lose a lot of money over time. Getting expert help to assist with the classification can help you determine the right amount of depreciation without losing any money in the process.
What Are The Capital Gains Impact of Claiming Division 43 Capital Works?
Expect some capital gains impact on your property if you claim a Division 43 deduction and sell your rental property in the future. Any deduction that you claim will be reduced from your cost base. This means that you could end up paying more capital gains in the future.
We understand that this may not sound ideal to you but bare in mind these two things:
First, capital gains are taxed at a preferential rate (50% exemption). Second, the time value of money means that a dollar of extra cash now is worth more than potential tax savings in the future.
This also allows you, the investor, to invest the extra money or reduce loan liabilities. Those are extra savings you could be using today.
