How Does a Lease Renewal Affect My Depreciation Schedule?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

A lease renewal can impact your property's depreciation schedule by potentially altering the effective life of depreciating assets under **Division 40 of ITAA 1997**. Changes to the property's use or tenant improvements can necessitate an update to the schedule. Consult a QS for accurate adjustments.

When a lease is renewed, it can have significant implications for your property's depreciation schedule. Under Division 40 of ITAA 1997, plant and equipment (depreciating assets) are depreciated over their effective life. A lease renewal may involve changes to these assets, such as replacements or upgrades, which can affect the depreciation claims. It's crucial to understand how these changes impact your tax deductions.

A common misconception is that a lease renewal automatically resets the depreciation schedule. In reality, only specific changes to the assets or their use might necessitate adjustments. For instance, if the renewal involves significant tenant improvements, these additions need to be integrated into the schedule. Conversely, if the lease renewal does not involve any changes to the property, the existing depreciation schedule may remain unchanged.

To see how this plays out, consider a practical example: Imagine a 2015-built commercial office in Melbourne with an original fit-out valued at $150,000. Upon lease renewal, the tenant requests new carpeting and lighting upgrades worth $25,000. These upgrades are considered new assets and can be depreciated separately. Assuming a marginal tax rate of 37%, the depreciation on these new assets could reduce your tax liability by approximately $9,250 over their effective life.

In our experience reviewing thousands of properties across Australia, we often find that landlords overlook the need to update their depreciation schedule post-lease renewal. This oversight can lead to missed tax benefits. Additionally, many investors fail to account for the residual value of removed assets, which can still offer tax deductions. Another common pattern is underestimating the impact of tenant-specific improvements on the overall depreciation strategy.

The answer can differ depending on your situation. For instance, if the lease renewal occurs after significant legislative changes, such as the 2017 budget amendments, the ability to claim depreciation on certain assets might be restricted. Additionally, properties owned by SMSFs may have specific requirements regarding lease renewals and depreciation. Commercial properties often have different depreciation rules compared to residential properties, which can also affect the schedule.

When it comes to lease renewals and depreciation, individual circumstances play a significant role. Engaging a Chartered Quantity Surveyor ensures that your depreciation schedule accurately reflects any changes, maximizing your tax benefits. Additionally, consulting with your accountant can provide a comprehensive understanding of how lease renewals impact your overall tax situation.

Here's what to do next:

  • Review your existing depreciation schedule before the lease renewal.
  • Assess any changes or improvements made to the property during renewal.
  • Engage a Chartered Quantity Surveyor to update your depreciation schedule if necessary.
  • Consult with your accountant to understand the tax implications of the lease renewal.
  • Monitor any legislative changes that may affect your depreciation claims.
  • Keep detailed records of all improvements and changes for future reference.
