How to Assess Depreciation Potential Before Buying

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

To assess a property's depreciation potential before buying, consider both Division 40 (plant and equipment) and Division 43 (capital works) under ITAA 1997. Evaluate the age of the building, the quality of fixtures, and the property's history. Consulting a Quantity Surveyor is crucial for an accurate estimate.

Evaluating the depreciation potential of a property before purchase is a crucial step for investors looking to maximise tax deductions. Depreciation allows you to claim a deduction for the decline in value of the building and its fixtures over time, which can significantly impact your investment's cash flow.

Under Division 40 of ITAA 1997, plant and equipment assets, such as air conditioning units and carpets, can be depreciated. Meanwhile, Division 43 covers capital works deductions, which apply to the building's structural elements like walls and floors. To assess depreciation potential, you need to understand both divisions and how they apply to your prospective property.

A common misconception is that all properties offer the same depreciation benefits. However, the potential varies greatly depending on factors such as the property's age, the quality and type of fixtures, and any recent renovations. Properties built after 16 September 1987 are eligible for capital works deductions, but the plant and equipment depreciation rules changed significantly in 2017. For residential properties acquired after 9 May 2017, you cannot claim Division 40 deductions on previously used plant and equipment.

To see how this plays out, let's consider a 2015-built three-bedroom house in Melbourne, purchased for $750,000. The property includes modern fixtures and quality appliances. With a detailed depreciation schedule prepared by a Quantity Surveyor, you could expect to claim around $10,000 in the first year alone. If you're in the 37% tax bracket, this could reduce your tax bill by approximately $3,700.

In our experience reviewing thousands of properties across Australia, we find that many investors overlook the impact of renovations and the year of construction on depreciation potential. Newer properties or those with recent upgrades often offer greater deductions. Additionally, many investors fail to obtain a professional depreciation schedule, which can lead to missed opportunities for tax savings.

The answer can differ depending on your situation. For example, if you're buying a commercial property, the depreciation rules differ slightly, as they are not subject to the 2017 budget changes affecting residential properties. Similarly, if you're purchasing a property through a self-managed super fund (SMSF), the tax implications and potential deductions might vary. Joint ownership scenarios and properties that have only been partially owned during the year also require specific considerations.

Given the complexity and the potential financial impact, obtaining professional advice is essential. A Chartered Quantity Surveyor can provide a detailed depreciation schedule tailored to your property, while an accountant can help integrate this into your overall tax strategy.

  • Consult a Quantity Surveyor to get a depreciation schedule estimate for the property you're considering.
  • Evaluate the property's age and any recent renovations to determine potential capital works deductions.
  • Consider the quality and type of plant and equipment for Division 40 deductions.
  • Check if the property is eligible for any government incentives or grants that might affect depreciation.
  • Discuss with your accountant how these deductions will fit into your broader tax strategy.
  • Make a confident purchase decision knowing the potential tax benefits.
  • Frequently Asked Questions

    Can I claim depreciation on an old property?

    Yes, but the depreciation potential is generally lower. Capital works deductions apply to properties built after 16 September 1987. Older buildings may have limited eligibility.

    Do renovations affect depreciation claims?

    Yes, renovations can significantly impact depreciation potential. Recent upgrades often increase eligible deductions under Division 43.

    How does location impact depreciation?

    Location itself doesn't directly affect depreciation, but the local property market can influence the quality and age of properties available.

    How does depreciation affect my tax return?

    Depreciation reduces your taxable income, leading to lower tax liability. Ensure your accountant includes this in your annual tax return.

    Are there state-specific depreciation rules?

    Depreciation rules are federal, but local building regulations may affect construction costs and, subsequently, capital works deductions.
