A Property Tax Depreciation Schedule Will Save You Money

A Tax Depreciation Schedule can help you save money by reducing your taxable income and therefore lowering your tax liability. For investment property owners in Australia, depreciation is one of the most valuable — and most frequently overlooked — deductions available. Unlike most other expenses, depreciation is a non-cash deduction: you don't spend money to claim it, you simply recognise the natural wear and decline in value of the building and its assets over time.

How Property Tax Depreciation Works

When you own an investment property that generates rental income, the ATO allows you to claim deductions for the decline in value of certain elements of the property. These deductions are split across two categories:

• Division 43 – Capital Works: The building structure and fixed items. For residential properties constructed after 18 July 1985, you can claim 2.5% per year of the original construction cost. This deduction can continue for up to 40 years.
• Division 40 – Plant & Equipment: Individual depreciable assets such as carpets, appliances, air conditioning units, hot water systems and other removable or mechanical items. Each asset is depreciated over its effective life as set by the ATO.

Together, these two categories can produce significant annual deductions — and a professionally prepared Tax Depreciation Schedule by a registered Quantity Surveyor ensures every legitimate deduction is captured.

What Does This Mean in Practice?

The practical effect of a depreciation deduction is a reduction in your taxable income. For an investor in the 37% tax bracket (taxable income between $135,001 and $190,000 for 2024–25), every $1,000 in depreciation deductions saves $370 in tax. These are real dollars back in your pocket each year, simply from owning the property.

An Illustrative Example

Consider an investor who purchased a two-bedroom apartment in Melbourne for $650,000. The property was built in 2005 and has a construction cost estimate of $180,000.

• Division 43 deduction: $180,000 × 2.5% = $4,500 per year
• Division 40 deduction (Year 1): Approximately $3,200 across carpets, appliances, blinds and other assets
• Total Year 1 depreciation: approximately $7,700

For an investor in the 37% tax bracket, this equates to a tax saving of approximately $2,849 in the first year alone. The Division 43 deduction of $4,500 continues for every year of ownership (reducing your cost base accordingly), and the Division 40 assets continue to depreciate on their respective effective lives.

The Schedule Pays for Itself Many Times Over

An MTD Tax Depreciation Schedule is a one-time cost that covers your property for its full 40-year claimable life. When you consider that the first year's tax saving alone typically far exceeds the cost of the schedule, the investment calculus is straightforward. Year after year, the schedule continues to generate deductions for your accountant to apply, at no ongoing cost to you.

How Much Could You Save Over the Life of Your Investment?

Over a 10-year holding period, the same apartment in our example above could generate Division 43 deductions alone totalling $45,000 — representing tax savings of over $16,000 for a 37% taxpayer. When you add the cumulative Division 40 deductions in the earlier years, the total benefit is substantially higher.

Properties with higher construction costs — such as high-rise apartments, large houses or commercial premises — can generate proportionally greater deductions.

Do I Need a Quantity Surveyor to Prepare My Schedule?

Yes. The ATO requires that Tax Depreciation Schedules for investment properties be prepared by a qualified Quantity Surveyor — a professional who is specifically trained in construction cost estimation and building valuation. Self-prepared estimates are not accepted for Division 43 purposes. A Tax Agent (accountant) cannot prepare the construction cost estimates themselves.

Melbourne Tax Depreciation's principal, Erik Abbenhuys, is a Member of the Australian Institute of Quantity Surveyors (MAIQS) with over 50 years of experience in Quantity Surveying and has been preparing Tax Depreciation Schedules since 1981. Our schedules are ATO-compliant, professionally presented and designed to be used directly by your accountant.

When Is the Right Time to Get a Schedule?

The best time to arrange a Tax Depreciation Schedule is as early as possible after purchasing an investment property. Deductions can be backdated to the date the property was first available for rent, so even if you have owned your property for several years without a schedule, it is not too late. A schedule can be prepared retrospectively, and your accountant may be able to amend prior year returns to access missed deductions (subject to the ATO's amendment time limits).
