Bought an investment property mid-year? Don’t miss out on partial year depreciation

First published 3 November 2026

If you bought an investment property partway through the financial year, you may still be able to claim partial year depreciation in your first tax return. The amount you can claim depends on key dates, including when you acquired the property and when it was genuinely available for rent.

Partial year depreciation allows eligible depreciation deductions to be calculated for the portion of the financial year that the property was available to produce income.

For investors approaching the end of the financial year, overlooking this first partial-year claim can mean delaying a tax benefit that may already be available.

What is partial year depreciation?

Property depreciation is the natural decline in value of a building and eligible assets over time due to wear and tear. The Australian Taxation Office (ATO) allows eligible property investors to claim depreciation as a tax deduction.

When an investment property is acquired during a financial year, the first depreciation claim will often cover less than twelve months. This is known as partial year depreciation, and even a few months of ownership can generate valuable deductions that reduce taxable income and improve an investor’s after-tax cash flow.

Partial year depreciation deductions are calculated according to the period the property was available for income-producing purposes during that financial year.

A partial year of ownership does not automatically mean there is no depreciation claim. The deduction reflects the eligible period and the property’s circumstances.

When does depreciation start?

Buying an investment property does not automatically mean depreciation starts on the purchase date.

For rental properties, the date the property is genuinely available for rent is critical.

This distinction matters when there is a gap between settlement and the property becoming available to tenants. An investor may settle on a property and then spend several weeks completing repairs, renovations or other work before advertising it for rent. In these circumstances, the relevant dates must be accurately recorded so the depreciation claim reflects the property's actual income-producing use and eligibility.

Likewise, simply intending to rent a property is not necessarily enough. The circumstances need to demonstrate that it was genuinely available for rent.

Accurate records can include:

  • Settlement and ownership documents
  • Property management agreements
  • Rental advertising records
  • Lease commencement dates
  • Records of renovations or repairs completed before leasing

These records give the investor, quantity surveyor and accountant clearer support for the dates used in the depreciation calculation.

Pro rata depreciation explained

Pro rata depreciation means calculating a deduction according to the eligible portion of the financial year rather than automatically claiming the amount that would apply across a full year.

Consider a simplified example.

Assume the property would generate a $10,000 capital works deduction for a full financial year. The investment property is genuinely available for rent for 183 days before June 30.

A simplified pro rata calculation would be:

$10,000 × 183 ÷ 365 = $5,014

The investor could therefore have a capital works deduction of approximately $5,014 for that partial financial year, subject to the property meeting the relevant eligibility requirements.

The calculation of plant and equipment depreciation can be more complex because individual assets have different effective lives and depreciation methods. The number of days an asset is held and used, or installed ready for use, for a taxable purpose can also affect the deduction.

A professionally prepared tax depreciation schedule accounts for the relevant timing rather than simply applying a full-year figure to a property purchased partway through the year.

Partial year claims can include capital works and plant and equipment

Depending on the property and the investor’s eligibility, depreciation deductions generally fall into two categories.

Capital works (Division 43)

Capital works deductions apply to eligible construction expenditure relating to the building structure and permanently fixed items.

For eligible residential properties, these deductions are generally available at 2.5 per cent per year for up to forty years from the relevant construction completion date.

A property does not need to be owned for the entire financial year for an eligible investor to claim capital works deductions. The first-year deduction can reflect the period the property was used to produce assessable income or was genuinely available for that purpose.

Plant and equipment (Division 40)

Plant and equipment includes eligible removable or mechanical assets such as air conditioners, blinds, carpets, appliances and hot water systems.

Each asset has an effective life that affects how depreciation is calculated.

Residential investors must also consider the legislation affecting previously used plant and equipment. In general, investors who acquire second-hand residential properties cannot claim depreciation on previously used plant and equipment assets where the restrictions apply. However, eligible new assets purchased and installed for the income-producing property may still provide deductions.

This makes correct asset classification and eligibility assessment particularly important in the first year of ownership.

Why partial year depreciation matters for cash flow

Depreciation is a non-cash tax deduction. An investor does not need to incur the depreciation amount as an annual expense to claim an eligible deduction.

Instead, depreciation can reduce taxable income, which may reduce the amount of tax payable.

This can be particularly valuable during the acquisition stage. Buying an investment property can involve substantial costs, from the deposit and acquisition expenses to loan repayments, property management costs, insurance and initial maintenance.

Claiming every eligible deduction from the first financial year can help offset some of the financial pressure associated with holding the property.

This remains relevant even when the property becomes available for rent late in the financial year. A property that becomes genuinely available for rent in May or June may still generate eligible partial year depreciation deductions before June 30. The same schedule can also provide depreciation information for future years, subject to the property and investor remaining eligible.

Why waiting to arrange a schedule can be costly

Depreciation is often considered at tax time rather than at acquisition. Waiting until after changes have been made to the property can make it harder to document what was present at acquisition.

This is particularly important if renovations or asset replacements are planned.

If eligible assets or structural elements are removed before a quantity surveyor assesses the property, valuable information about the property's existing depreciation entitlements may be lost. Investors may also overlook potential scrapping deductions for eligible items removed during a renovation.

A site inspection helps a specialist quantity surveyor identify eligible construction and assets, including items that may not be obvious from purchase documents alone.

Accurate dates, asset classifications and property-specific information support a more reliable depreciation schedule and give the investor’s accountant clearer information to work from. BMT Tax Depreciation uses site inspection findings, ownership information and property records to identify eligible capital works and plant and equipment and prepare the depreciation schedule.

EOFY considerations for new property owners

Investors who acquire property during the financial year should confirm their depreciation deductions before preparing their tax return.

Check that:

  • Settlement and ownership dates are accurate
  • The date the property became genuinely available for rent is documented
  • Renovations and improvements have been recorded
  • New assets purchased for the property have been identified
  • A tax depreciation schedule has been prepared where depreciation deductions are available

A professionally prepared tax depreciation schedule provides the figures required for eligible claims and can generally be used across the depreciable life of the property.

This is particularly important where construction costs are unavailable. Specialist quantity surveyors such as BMT Tax Depreciation are recognised under ATO Taxation Ruling TR 97/25 as appropriately qualified to estimate construction costs for depreciation purposes.

The bottom line

Buying an investment property partway through the financial year does not remove the opportunity to claim depreciation. Partial year depreciation can provide eligible deductions from the first year of ownership, with the claim calculated according to the relevant income-producing period and depreciation rules.

Accurate settlement details, rental availability dates and asset information are essential. Even where only a few months remain before June 30, eligible depreciation deductions can reduce taxable income and improve after-tax cash flow.

Waiting for a full financial year before arranging a tax depreciation schedule can unnecessarily delay those benefits and increase the risk of valuable information being lost, particularly if renovations or asset replacements occur.

BMT Tax Depreciation can inspect the property, identify eligible capital works and plant and equipment deductions and prepare an accurate, compliant tax depreciation schedule that accounts for the investor’s first partial financial year.
