An owner-builder is someone who assumes the role of a builder to construct or renovate their own property, often to save on costs. While this can be a rewarding venture, it introduces complexities in claiming depreciation, which is crucial for maximising tax benefits.
Under Division 40 of ITAA 1997, you can claim depreciation on plant and equipment, while Division 43 covers capital works deductions for structural improvements. As an owner-builder, you're responsible for ensuring all costs are meticulously documented. This means tracking every receipt, invoice, and contract to substantiate your claims. The most common misconception is that owner-builders can claim depreciation as if they were commercial builders, but the ATO requires detailed costings and evidence of expenses.
Take a practical example of a 2010-built 4-bedroom house in Geelong, purchased for $900,000. As an owner-builder, you renovate the kitchen and bathrooms, spending $50,000 on plant and equipment and $100,000 on structural improvements. Under Division 40, you could claim depreciation on new appliances, cabinets, and fixtures. Assuming a 20% depreciation rate on the plant and equipment, you could deduct $10,000 in the first year. For Division 43, assuming a 2.5% rate over 40 years, you'd claim $2,500 annually on the structural improvements. At a 37% marginal tax rate, this reduces your tax bill by $4,625 in the first year.
In our experience reviewing thousands of properties across Australia, owner-builders often underestimate the importance of maintaining a detailed record of all construction costs. Many fail to realise that without proper documentation, the ATO may disallow their claims. Additionally, owner-builders frequently miss out on claiming eligible depreciation for assets they assumed were ineligible, such as plumbing and electrical systems. Another common oversight is not engaging a professional Quantity Surveyor early in the process, which can lead to missed opportunities for maximising deductions.
The answer can differ depending on your situation. If you acquired a second-hand property after 9 May 2017, the ability to claim Division 40 depreciation on used plant and equipment is restricted. Properties built before 1987 may not qualify for Division 43 deductions unless substantial renovations have been made. If the property is held within a Self-Managed Super Fund (SMSF), different rules apply, particularly concerning the fund's ability to claim deductions. Joint ownership can also complicate claims, as depreciation must be apportioned according to ownership percentage. A partial year of ownership requires prorating deductions based on the time held.
Given the complexities involved, consulting both a Chartered Quantity Surveyor and an accountant is essential. They can ensure all documentation is in order, maximise your deductions, and help navigate the nuances of ATO requirements effectively. Each property, and indeed each owner-builder situation, can have unique factors that influence the optimal depreciation strategy.
