What Should an Australian Rental Property Depreciation Schedule Prove in 2026?

Part of the Rental Rule Changes Watch 2026 series.

This guide is for Australia-wide federal tax. It uses Australian Taxation Office guidance current when reviewed on 2 July 2026. It does not cover state or territory tenancy law in New South Wales, Victoria, Queensland, South Australia, Western Australia, Tasmania, the Australian Capital Territory, or the Northern Territory.

What Is a Depreciation Schedule?

A depreciation schedule is the working document that turns construction costs and eligible depreciating assets into annual tax deductions.

For Australian rental property, the schedule usually has two lanes:

• Division 40 plant and equipment depreciation for removable or mechanical assets that decline in value
• Division 43 capital works deductions for eligible building construction costs and structural improvements

The schedule should not be treated as a one-line deduction number. It is evidence. It should explain what was claimed, why it was claimable, and which records support the calculation.

What Does the Australian Taxation Office Say About Depreciating Assets?

The Australian Taxation Office page on depreciating assets in rental properties, last updated on 21 May 2026, describes depreciating assets as plant that does not form part of the rental property premises. It gives a dishwasher in a rental property held to produce assessable income as an example of an asset where a decline-in-value deduction may be available.

That means a useful Division 40 section should show:

The Australian Taxation Office also says it recommends keeping at least a spreadsheet for depreciating assets as part of record keeping. A property folder should therefore keep the schedule and the invoices together, not just the accountant’s final return figure.

Why Are Second-Hand Assets a Separate Test?

Second-hand plant and equipment is one of the easiest Australian rental depreciation mistakes to make.

The Australian Taxation Office page on second-hand depreciating assets says deductions for second-hand or used depreciating assets in residential rental properties are generally limited. It identifies a key timing rule: the asset must have been purchased before 7:30 pm on 9 May 2017 and installed into the rental property before 1 July 2017, unless an exception applies.

In practice, the file needs to answer:

1. Did the current owner buy the asset new?
2. Did the asset come with an established residential property?
3. Was the asset purchased before or after 7:30 pm on 9 May 2017?
4. Was the property brand new or substantially renovated when acquired?
5. Is the owner an entity type covered by an exception?

Do not let the schedule list all appliances as if the same rule applies to every owner. The acquisition date, asset history, and ownership structure matter.

What Should the Capital Works Section Prove?

The Australian Taxation Office page on capital works deductions, last updated on 22 June 2026, says a capital works deduction can generally be claimed for construction costs over 40 years from completion, but the owner needs details such as construction type, commencement date, completion date, construction cost, who carried out the construction, and the period the property was used to produce income.

For a Division 43 file, keep:

• construction commencement date
• construction completion date
• original construction cost, not the purchase price
• builder, developer, or quantity surveyor evidence
• structural improvement invoices
• dates the property was rented or genuinely available for rent
• annual Division 43 amounts claimed
• records of any capital works notice received from a vendor

Why Does Capital Gains Tax Need the Same File?

Depreciation is not just a tax-return-year issue.

The Australian Taxation Office page on cost-base adjustments for capital works, last updated on 22 June 2026, says capital works deductions that can be claimed against income cannot generally be included in the cost base or reduced cost base of an asset. That can matter years later when the property is sold.

For future capital gains tax work, preserve:

• each year’s Division 43 deduction claimed
• deductions that could have been claimed but were missed, where relevant to the Australian Taxation Office rule
• construction-cost reports
• capital improvement invoices
• sale contract and settlement records
• accountant working papers that explain the cost-base treatment

This is why the depreciation schedule belongs in the permanent property file, not only in the annual tax folder.

When Is the Australian Taxation Office Tool Enough?

The Australian Taxation Office depreciation and capital allowances tool can calculate depreciation amounts for rental properties, capital works, asset-based depreciation, and compare prime cost and diminishing value methods. It can also save or download calculations for records or a tax agent.

That tool may be useful for straightforward items. It is not a substitute for missing construction-cost evidence, complex ownership history, or unclear second-hand asset treatment. Where a property has material capital works, old construction records, renovations by previous owners, or mixed-use periods, the file needs source documents and professional working papers.

Practical Filing Pattern

For each Australian rental property, keep these folders:

1. depreciation-schedule
2. division-40-assets
3. division-43-capital-works
4. construction-cost-evidence
5. new-and-second-hand-asset-test
6. income-producing-use-calendar
7. capital-gains-tax-cost-base
8. accountant-workpapers

The schedule should link to source documents. For example, a dishwasher line should point to the invoice, installation date, and whether it was new. A building capital works line should point to the construction-cost estimate or builder records.

Source Note

This article is specific to Australia-wide federal tax. It relies on Australian Taxation Office guidance on depreciating assets in rental properties, second-hand depreciating assets, capital works deductions, capital works cost-base adjustments, and the depreciation and capital allowances tool. It is general information about records and source documents, not personal tax advice.

Last reviewed: 2 July 2026. The Australian Taxation Office pages cited above were listed as updated in May and June 2026 when reviewed. Confirm the current rules with the Australian Taxation Office or a registered tax agent before claiming depreciation, amending a tax return, or calculating a capital gain or loss.

The Short Version

1. A depreciation schedule should separate Division 40 assets from Division 43 capital works.
2. Second-hand plant and equipment needs a separate acquisition-date and asset-history test.
3. Capital works deductions need construction-cost evidence, not just purchase price or insured value.
4. Annual Division 43 claims can affect later capital gains tax cost-base calculations.
5. Keep the schedule, source invoices, construction reports, income-use dates, and accountant workpapers in one permanent property file.
