Can I Claim Scrapping When I Demolish Old Assets?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Yes, you can claim scrapping deductions when you demolish old assets, provided they were part of your investment property and you have not fully depreciated them. Under Division 43 of the ITAA 1997, you can claim the remaining undeducted construction costs of the demolished assets, provided you have a compliant depreciation schedule. Consult a Chartered Quantity Surveyor for accurate assessments.

Scrapping, in the context of property investment, refers to claiming a tax deduction for the remaining value of assets that are demolished or removed. This is particularly relevant when you undertake substantial renovations or redevelopments. It's a valuable opportunity often overlooked by property investors, especially when demolishing older parts of a building.

How Scrapping Deductions Work

Scrapping deductions allow you to claim the remaining undeducted value of assets when you demolish them. Under Division 43 of the ITAA 1997, investors can claim the remaining construction costs of the demolished assets, provided they form part of an investment property. The key is that these assets should not be fully depreciated. The most common misconception is that investors cannot claim anything once an asset is removed—this is incorrect. As long as you have a detailed and compliant depreciation schedule, you can claim the remaining undeducted value of these assets.

How This Works in Practice

Consider an investor who owns a 1960s-built single-storey house in Richmond, Melbourne, purchased for $950,000. The investor decides to demolish the old kitchen and bathroom, both of which have undepreciated values listed in a depreciation schedule. The kitchen's undepreciated value is $5,000, and the bathroom's is $3,500. By claiming scrapping, the investor can write off these amounts in the year of demolition, reducing their taxable income by $8,500. At a marginal tax rate of 37%, this results in a tax saving of approximately $3,145 for that financial year.

Professional Insight

In our experience, many investors miss out on scrapping deductions simply because they don't realise they are available. One thing we frequently see is investors demolishing parts of a property without a current depreciation schedule, which means they can't substantiate their scrapping claims. Another common oversight is not consulting a Quantity Surveyor before demolition, resulting in missed opportunities for accurate deductions. Investors should also be aware that scrapping is not limited to major renovations—smaller updates can also qualify if they involve removing older assets. Finally, remember that scrapping applies only to investment properties, not primary residences.

When Does the Answer Change?

  • Post-9 May 2017 Acquisitions: If you acquired a second-hand residential property after this date, you cannot claim scrapping on Division 40 assets.
  • Pre-1987 Buildings: For properties built before 1987, special rules apply, and scrapping may not be as straightforward.
  • Partially Depreciated Assets: If an asset is fully depreciated, you cannot claim any scrapping deduction.
  • Commercial Properties: Different rules may apply, and often more generous scrapping options exist.
  • When Should You Seek Professional Advice?

    Seek professional advice when dealing with complex renovations or demolitions. A Chartered Quantity Surveyor will ensure that you accurately assess the undepreciated value of your assets. Additionally, your accountant can help integrate these deductions into your broader tax strategy. These professionals work together to maximise your deductions while ensuring compliance with ATO regulations.

    What to Do Next

  • Review Your Depreciation Schedule: Ensure it is up-to-date and includes all assets.
  • Consult a Quantity Surveyor: Before demolition, get a QS to assess the undepreciated value of assets.
  • Plan Your Renovations: Understand which assets can be scrapped and their values.
  • Coordinate with Your Accountant: Integrate scrapping deductions into your tax planning.
  • Document Everything: Keep records of all demolition activities and valuations.
