A depreciation schedule is a detailed report prepared by a quantity surveyor or valuation professional that identifies all depreciable assets in a property or business.
Depreciation represents the decline in value of assets over time, and the ATO allows business owners and property investors to claim these deductions against taxable income.
From a business valuations perspective, a schedule does more than reduce tax — it also provides:
- Accurate asset valuations for balance sheets
- Supporting documentation for ATO compliance
- Insight into the long-term value and replacement costs of assets
Why a Tax-Effective Depreciation Schedule Matters in 2025
As tax rules evolve, ensuring your depreciation schedule is accurate and compliant is critical for maximising deductions and avoiding audit issues.
In 2025, business owners and property investors can benefit from a schedule in several ways:
- Maximise allowable deductions
- Structural elements and plant & equipment can be claimed over their effective life.
- A professionally prepared schedule identifies assets you might overlook, increasing potential tax savings.
- Support for business valuations
- Accurate depreciation reporting ensures that the asset base of a business reflects true value for sale, acquisition, or reporting purposes.
- This is particularly important for SMEs, family businesses, and property-based businesses.
- Compliance with ATO requirements
- Using a professional depreciation schedule reduces the risk of the ATO disputing deductions.
- The ATO’s guide on depreciation outlines the rules for claiming both building and plant & equipment depreciation.
How to Obtain a Tax-Effective Depreciation Schedule
1. Engage a Qualified Quantity Surveyor or Valuation Expert
A qualified quantity surveyor or certified business valuer can prepare a schedule that:
- Identifies all depreciable assets
- Classifies them correctly for ATO purposes
- Calculates the appropriate deduction over the asset’s effective life
Using an experienced professional ensures that your schedule is tax-effective and compliant, maximising deductions without risking non-compliance.
2. Include Both Building and Plant & Equipment Assets
Depreciation schedules can cover:
- Building structure items – walls, floors, windows, roofs
- Plant & equipment – furniture, machinery, air conditioning, commercial kitchen items
Separating these categories allows business owners to claim capital works deductions (Division 43) and plant & equipment deductions (Division 40) efficiently.
A professional valuation ensures you claim everything you’re entitled to under the 2025 rules.
3. Integrate Your Schedule With Your Business Valuation
For business owners, schedules are essential in valuations because they:
- Adjust the asset base for current market value
- Reflect the realistic remaining useful life of assets
- Assist in exit planning, sale negotiations, and loan applications
At WA Business Valuations, we combine schedules with business valuations to provide a holistic view of your asset base and tax position.
4. Update the Schedule After Major Purchases or Renovations
Depreciation schedules should not be static. Any significant capital improvements, renovations, or new equipment purchases require an updated schedule to remain tax-effective.
Failing to update your schedule can result in:
- Missed deductions
- Overstated asset values in your balance sheet
- Potential ATO compliance issues
5. Use the Schedule to Plan Tax Strategy Year-Round
A professional depreciation schedule allows you to:
- Forecast tax deductions and cash flow
- Make informed decisions on asset replacement or upgrades
- Optimise your 2025 tax position for both business and investment properties
By integrating depreciation into broader business valuations and tax planning, you can maximise both deductions and business value.
