Understanding depreciation is one of the most powerful tools available to property investors but it’s also one of the most misunderstood. One of the most common questions investors ask TDA Tax Depreciation is:
What’s the difference between capital works and plant and equipment, and why does it matter?
The answer can have a significant impact on your annual tax deductions and long-term cash flow.
What Is Capital Works?
Capital works refer to the structural elements of a building and permanent improvements that form part of the property itself. These assets are generally depreciated at a fixed rate of 2.5% per year, over 40 years.
Capital works typically include:
- Building structure (walls, roof, concrete slabs)
- Fixed cabinetry and joinery
- Bathrooms and tiling
- Doors, windows and staircases
- Built-in cupboards
- Structural renovations and extensions
The best way to think of capital works is if you were to flip the house onto its roof and shake it, then everything that stays where it is falls into this category.
For residential properties, capital works deductions usually apply to buildings constructed after 15 September 1987, or where eligible renovations have been completed since that time.
While capital works deductions are spread over a longer period, they provide consistent, long-term tax benefits year after year.
What Is Plant and Equipment?
Plant and equipment refers to removable or mechanical assets within a property that have a shorter effective life than the building itself. These assets typically depreciate faster, meaning larger deductions earlier in the ownership period.
Examples of plant and equipment include:
- Air conditioners and ceiling fans
- Ovens, cooktops and rangehoods
- Dishwashers and laundry appliances
- Hot water systems
- Carpet, blinds and curtains
- Light shades and exhaust fans
- Garage motors and security systems
To use the example above, generally anything that moves or falls out during the shaking of the upside down house falls under plants and equipment.
Because these assets wear out more quickly, the Australian Tax Office allows them to be depreciated over shorter timeframes, often resulting in higher first-year deductions.
Why Does the Difference Matter?
The distinction between capital works and plant and equipment is critical because it affects how quickly deductions can be claimed, the total value of your depreciation schedule and your annual cash flow and tax position.
Plant and equipment generally deliver stronger deductions earlier, while capital works provide steady deductions over the long term. A well-prepared depreciation schedule balances both to maximise overall benefit.
What About Changes to the Rules?
For residential investment properties exchanged after 9 May 2017 from 7.30pm, investors are unable to claim depreciation on previously used plant and equipment. However, brand-new plant and equipment installed after purchase by the client is still claimable, the capital works deductions are unaffected and
Commercial properties are not subject to the same restrictions.
This is where professional advice becomes essential, understanding what is eligible, and when, can make a substantial difference.
