What is a Commercial Depreciation Schedule?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

A commercial depreciation schedule outlines the tax deductions available for the decline in value of a property’s structure and assets. Division 40 covers plant and equipment, while Division 43 applies to capital works. A professional schedule can significantly enhance your tax position by ensuring all eligible deductions are claimed.

Commercial property owners in Australia can significantly benefit from a depreciation schedule, which is a detailed report outlining the tax deductions available for the depreciation of a property's structure and its assets. This schedule ensures owners claim all eligible tax deductions, reducing their taxable income and improving cash flow.

Understanding Commercial Depreciation Schedules

A commercial depreciation schedule is a comprehensive report that details the depreciation deductions available for a commercial property. This includes deductions under Division 40, which pertains to plant and equipment, and Division 43, which relates to capital works. Division 40 covers items like carpets, air conditioning systems, and other fixtures, while Division 43 involves the structural elements of the building, such as walls and roofing.

A common misconception is that only new properties qualify for depreciation deductions. However, even older properties and those with second-hand assets can benefit, particularly through Division 43, which can apply to buildings constructed after 16 September 1987.

How This Works in Practice

Consider a retail building in Melbourne purchased for $1.5 million. The building was constructed in 2005, qualifying it for Division 43 deductions. A comprehensive depreciation schedule prepared by a Chartered Quantity Surveyor reveals annual deductions of $30,000 for capital works and $15,000 for plant and equipment. For a business owner with a 30% marginal tax rate, this results in a tax saving of $13,500 annually, significantly enhancing cash flow.

Professional Insight

In our experience, many business owners underestimate the potential savings from a commercial depreciation schedule. One thing we frequently see is owners not updating their schedules after renovations, missing out on additional deductions. Some owners also mistakenly believe that only new properties are eligible for deductions, ignoring valuable opportunities in older buildings. Additionally, many do not realise the importance of engaging a qualified Quantity Surveyor, which can lead to incomplete or inaccurate schedules. Owners often overlook the impact of their marginal tax rate on the actual savings from depreciation. Lastly, we see a lack of awareness about the necessity of separate schedules for different property types within a portfolio.

When Does the Answer Change?

The general approach to commercial depreciation schedules can differ in several situations:

  • Post-renovation: Renovations can significantly alter the depreciation landscape. New assets and improvements can be claimed under the appropriate divisions.
  • Pre-1987 buildings: While Division 43 generally applies to buildings constructed after 1987, certain renovations or improvements might still qualify.
  • Mixed-use properties: Properties used for both commercial and residential purposes may require separate schedules for accurate deductions.
  • Properties with second-hand assets: The 2017 budget changes mainly affected residential properties, but commercial properties with second-hand assets may still qualify for deductions.

When Should You Seek Professional Advice?

While general information is valuable, individual circumstances can significantly affect depreciation claims. Complexities arise with mixed-use properties, extensive renovations, or unique asset classes. A Chartered Quantity Surveyor can provide a tailored depreciation schedule, ensuring all eligible deductions are claimed. It's also crucial to consult with an accountant to understand how depreciation fits into your broader tax strategy.

  • Update your schedule regularly, especially after making significant changes to your property.
