Do I Need to Update My Depreciation Schedule After Renovating?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Yes, you need to update your depreciation schedule after renovating to ensure all new capital works and plant and equipment are accurately accounted for. This allows you to claim the maximum depreciation deductions available under Division 40 and Division 43 of the ITAA 1997, optimising your tax benefits.

Renovating your investment property can significantly enhance its value and rental appeal. However, many investors overlook the importance of updating their depreciation schedule post-renovation, potentially missing out on significant tax deductions.

Why Updating Your Depreciation Schedule After Renovating is Essential

When you renovate, any new assets installed or structural improvements made can affect the depreciation deductions you can claim. Under Division 40 of the ITAA 1997, new plant and equipment, such as appliances or carpets, can be depreciated over their effective life. Similarly, Division 43 allows for deductions on capital works, like extensions or structural renovations, over a period of 40 years. The most common misconception is that a depreciation schedule only needs to be set up once, but in reality, it should be updated to reflect any changes made to the property to maximise tax benefits.

How This Works in Practice

Consider a scenario where you own a 2009-built, 2-bedroom apartment in Fortitude Valley, Brisbane, purchased for $700,000. You decide to renovate the kitchen and bathroom, spending $50,000 on new cabinets, appliances, and fixtures. By updating your depreciation schedule, you can claim deductions on these new assets. Assuming a 37% marginal tax rate, this could result in additional tax savings of approximately $2,500 in the first year alone, depending on the effective life of the new assets.

Professional Insight

In our experience, failing to update a depreciation schedule is a common oversight among property investors. One thing we frequently see is investors underestimating the value of smaller renovations. Even minor upgrades can contribute to significant deductions. Another common issue is not retaining receipts or detailed records of the renovations, which can complicate the updating process. What most investors don't realise is that even demolishing parts of the property can offer deductions through scrapping, where the residual value of removed assets can be claimed.

When Does the Answer Change?

  • Pre-1987 Buildings: Properties constructed before 1987 are generally ineligible for Division 43 deductions unless renovations are substantial.
  • Post-9 May 2017 Acquisitions: Investors acquiring second-hand residential properties post-9 May 2017 should be aware they cannot claim Division 40 deductions on existing plant and equipment.
  • Commercial Properties: Different rules apply, and deductions often vary significantly from residential properties.
  • Joint Ownership: If a property is owned jointly, each owner must update their share of the depreciation schedule.
  • When Should You Seek Professional Advice?

    Updating a depreciation schedule can be complex, especially when renovations involve multiple components. It's advisable to consult with a Chartered Quantity Surveyor who can provide a comprehensive depreciation report, ensuring no deductions are overlooked. An accountant should also be involved to align the depreciation schedule with your overall tax strategy.

    What to Do Next

  • Document Renovations: Keep detailed records of all renovations, including costs and completion dates.
  • Consult a QS: Engage a Chartered Quantity Surveyor to assess your property and update the depreciation schedule.
  • Review Tax Strategy: Work with your accountant to integrate the updated schedule into your tax planning.
  • Check ATO Updates: Stay informed about any changes to depreciation rules or effective lives of assets.
  • Reassess Annually: Regularly review your depreciation schedule to adjust for new renovations or asset replacements.
  • Explore Scrapping Opportunities: Consider the tax benefits of scrapping old assets removed during renovations.
