Can Two Owners Claim Depreciation on the Same Property?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Yes, two owners can claim depreciation on the same property, but each must do so proportionately based on their ownership interest. Under **Division 40 and Division 43 of ITAA 1997**, each owner can claim their share of plant and equipment and capital works deductions. It's crucial to calculate depreciation based on the individual ownership percentage to ensure compliance with ATO guidelines.

When multiple individuals own a property, they can each claim depreciation, but only in proportion to their ownership interest. This applies to both Division 40, which covers plant and equipment, and Division 43, which addresses capital works. The Australian Taxation Office (ATO) requires that depreciation claims be apportioned according to each owner's percentage of ownership, ensuring that the total claim does not exceed 100% of the allowable depreciation.

A common misconception is that both owners can independently claim the full depreciation amount, which is incorrect and could lead to compliance issues. Instead, each owner must calculate their depreciation entitlement based on their ownership stake. For example, if two individuals own a property equally, each can claim 50% of the depreciation.

To see how this plays out, consider a practical example: Take a 2015-built townhouse in Richmond, Melbourne, jointly owned by two investors, each with a 50% stake. The property was purchased for $800,000, with plant and equipment valued at $50,000 and capital works at $300,000. In the first year, the total depreciation is calculated at $15,000 for plant and equipment and $7,500 for capital works. Each owner can claim $7,500 for plant and equipment and $3,750 for capital works. At a 37% marginal tax rate, each owner reduces their tax bill by $4,162.50 in the first year.

In our experience reviewing thousands of properties across Australia, we often see investors overlook the importance of accurately apportioning depreciation claims. Many assume they can claim more than their share, leading to ATO audits and penalties. Additionally, some investors fail to update their depreciation schedules when ownership percentages change, such as when one owner buys out the other. Another common oversight is not claiming depreciation at all due to misunderstanding eligibility based on ownership structure.

The answer can differ depending on your situation. For properties acquired after 7:30 pm AEST on 9 May 2017, second-hand residential properties cannot claim Division 40 depreciation on previously used plant and equipment if purchased by new owners. Pre-existing owners are grandfathered under the old rules. If the property is held in a Self-Managed Super Fund (SMSF), the depreciation must also be apportioned according to the fund’s ownership stake. Different rules may apply for commercial properties or if the property is used for business purposes.

Given the complexities involved, it is advisable to consult both a Chartered Quantity Surveyor and an accountant to ensure accurate and compliant depreciation claims. They can help determine the correct division of depreciation based on ownership stakes and provide tailored advice on how to maximise your deductions.

  • Identify Ownership Percentage: Determine each owner's share in the property.
  • Engage a Quantity Surveyor: Obtain a depreciation schedule tailored to your ownership percentage.
  • Consult an Accountant: Ensure your tax return accurately reflects your depreciation claim.
  • Review Annually: Update your depreciation schedule if ownership percentages change.
  • Monitor ATO Updates: Stay informed on any changes to depreciation rules that may affect your claim.
  • Frequently Asked Questions

    Can depreciation be split unevenly between owners?

    No, depreciation must be claimed in line with each owner's ownership percentage. Unequal splitting of depreciation claims is not compliant with ATO rules.

    How does depreciation work for properties in a trust?

    For properties held in a trust, depreciation is claimed by the trust itself, and the benefits are distributed according to the trust deed, usually as part of the beneficiaries' income.

    Do changes in ownership affect depreciation claims?

    Yes, any change in ownership percentages requires an updated depreciation schedule to reflect the new ownership structure and ensure accurate claims.

    Are there state-specific variations in depreciation rules?

    Depreciation rules are federally governed, so they are consistent across all Australian states. However, local property regulations may affect other tax considerations.

    How should depreciation be reported on a tax return?

    Each owner should report their share of the depreciation in their individual tax returns, ensuring it aligns with their ownership percentage and the depreciation schedule.
