Can I Claim Demolition Costs on My Investment Property?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Demolition costs can be claimed under **Division 43 of ITAA 1997** if they relate to capital works. However, they are not immediately deductible and must be added to the cost base for CGT purposes. Consult with a Chartered Quantity Surveyor and your accountant to ensure compliance with ATO guidelines.

Demolition costs are a common consideration for investors and developers when renovating or redeveloping a property. Understanding whether these costs can be claimed under Australian tax law can significantly impact your financial planning and tax outcomes.

Under Division 43 of ITAA 1997, demolition costs may form part of capital works expenditure. This means they are not immediately deductible but can be added to the cost base of the new construction or renovation. Consequently, they can be depreciated over time, typically at 2.5% per annum for residential properties built after 1987. The most common misconception is that demolition costs can be immediately written off, which is generally not the case.

To see how this plays out, consider a scenario where you purchase a 1980s-built residential property in Melbourne for $800,000 with plans to demolish and rebuild. The demolition costs amount to $50,000. These costs are added to the capital works expenditure of the new build, which totals $400,000. The total capital works cost is $450,000, allowing you to claim an annual depreciation deduction of $11,250 (2.5% of $450,000). At a 37% marginal tax rate, your tax saving is $4,162.50 annually.

In our experience reviewing thousands of properties across Australia, we find that many investors overlook the importance of properly documenting demolition costs. Failing to keep detailed records can lead to issues during tax assessments. Additionally, some investors mistakenly believe that demolition costs can be deducted from rental income, which is incorrect. Finally, combining demolition costs with other expenses without clear itemisation can result in inaccurate tax claims.

The answer can differ depending on your situation. If the property was acquired post-9 May 2017 and is a second-hand residential property, you cannot claim Division 40 depreciation on existing plant and equipment, but demolition costs can still be added to the capital works cost base. For properties owned by companies, the CGT discount does not apply, affecting how demolition costs contribute to your overall tax strategy. Pre-1987 buildings may have different considerations due to the lack of Division 43 eligibility.

Given the complexities involved, it's crucial to get professional advice. A Chartered Quantity Surveyor can accurately assess and document your demolition costs, ensuring compliance with the ATO. Your accountant can then integrate this information into your broader tax strategy, maximising your tax benefits.

  • Review your property's purchase and renovation plans to identify potential demolition costs.
  • Consult with a Chartered Quantity Surveyor to document these costs accurately.
  • Discuss the tax implications with your accountant, focusing on how to integrate demolition costs into your capital works schedule.
  • Keep detailed records of all demolition-related expenses, including invoices and contracts.
  • Monitor any changes in ATO legislation that might affect your ability to claim these costs.
  • Consider how the timing of your demolition and rebuild affects your overall investment strategy.
