What Assets Are Included in a Tax Depreciation Schedule?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

A tax depreciation schedule includes assets under Division 40 and Division 43 of the ITAA 1997. Division 40 covers plant and equipment, such as appliances and fittings, while Division 43 involves capital works like building structures. Understanding these can maximise your tax deductions.

Understanding what assets are included in a tax depreciation schedule is crucial for property investors looking to maximise their deductions. A tax depreciation schedule captures both plant and equipment assets, as well as capital works, and is guided by the Income Tax Assessment Act 1997 (ITAA 1997).

Assets Included in a Tax Depreciation Schedule

A tax depreciation schedule encompasses assets that fall under Division 40 and Division 43 of the ITAA 1997. Division 40 includes plant and equipment assets, which are items that can be easily removed or are not integral to the building's structure. Common examples are air conditioning units, carpets, and dishwashers. These assets are typically subject to depreciation based on their effective life as determined by the ATO.

Division 43 covers capital works, which refer to the structural elements of a building, such as walls, floors, and ceilings. These are generally depreciated over a longer period, usually 40 years at a set percentage rate per annum. It's important to note that for properties acquired after 7:30pm AEST on 9 May 2017, investors cannot claim Division 40 deductions for previously used plant and equipment in residential properties.

How This Works in Practice

Consider a 2015-built three-bedroom house in Richmond, Melbourne, purchased for $850,000. The property includes a variety of depreciable assets:

  • Plant and equipment, such as a reverse cycle air conditioner (effective life 10–15 years), valued at $3,000.
  • Carpets with an effective life of 8 years, valued at $4,000.
  • Capital works, including the building structure, valued at $400,000.
In the first year, the investor claims depreciation on the air conditioner and carpets under Division 40, and the capital works under Division 43. Assuming the investor is on a 37% marginal tax rate, these deductions could potentially save them around $5,000 in tax for the year.

Professional Insight

In our experience, investors often overlook the full range of assets that can be depreciated. One thing we frequently see is investors not realising that even small items like smoke alarms and blinds can be depreciated under Division 40. What most investors don't realise is that renovations, even if done by previous owners, can significantly boost capital works deductions. Another common oversight is failing to update the depreciation schedule after making improvements to the property, which can lead to missed deductions.

When Does the Answer Change?

  • Properties acquired post-9 May 2017: For residential properties, you cannot claim Division 40 deductions for previously used items if purchased after this date.
  • Pre-1987 buildings: These may not qualify for Division 43 deductions unless substantial renovations have been done.
  • Commercial vs Residential: Commercial properties are not subject to the same restrictions as residential properties regarding Division 40.
  • Properties held in an SMSF: The same depreciation rules apply, but the tax impact differs due to different tax rates.

When Should You Seek Professional Advice?

You should seek professional advice when dealing with unique property types, properties with extensive renovations, or when unsure about the effective life of assets. A Chartered Quantity Surveyor can provide a detailed depreciation schedule that maximises your deductions, while an accountant can ensure these are applied correctly in your tax return.

What to Do Next

  • Review your property to identify all plant and equipment assets.
  • Consult with a Chartered Quantity Surveyor to prepare a comprehensive depreciation schedule.
  • Ensure any renovations or improvements are included in your schedule.
  • Discuss with your accountant how to best apply these deductions to your tax return.
  • Revisit your depreciation schedule annually to incorporate any new assets or changes.
  • Stay informed about any legislative changes that may affect your deductions.

    What is the difference between Division 40 and Division 43?

    Division 40 relates to plant and equipment assets like appliances, while Division 43 covers capital works, which are structural elements of a building.
