Investment Property
Depreciation Calculator

The Duo Tax depreciation calculator is an accounting tool designed to help estimate and calculate the declining value of capital works and plant and equipment and relies on accurate figures to present accurate estimations. You can calculate your estimates using the straight-line depreciation method (prime cost) or the declining balance depreciation method (diminishing value).

Investment Return Calculations

Once you’re happy with the potential deduction estimates, you can get in touch with Duo Tax, who will conduct a property inspection to note all the depreciable items. Following the inspection, you should expect your tax depreciation schedule within two weeks.

A single schedule provides 40 years of claimable deductions (or the maximum entitled years), so you will only have to have your property inspected once. And the Quantity Surveyor fees are a property tax deduction.

Please note that this is only for indicative purposes and should not be used to claim on your tax return.

What is a Tax Depreciation Schedule?

As a building gets older, its structure and plant and equipment fixtures are subject to general wear and tear. So, each year, the value of the building and assets within the building decreases and depreciates. The Australian Taxation Office (ATO) allows property investors to claim the property depreciation as a tax deduction.

To calculate depreciation and determine the value of your investment property and plant and equipment, a qualified quantity surveyor must inspect your investment property and assign a value to each asset. A tax depreciation schedule is a comprehensive report that details the tax depreciation deductions you can claim on the value of these assets.

Depreciation Calculator



The Depreciation Calculator provides you with an indication of depreciation only; your Quantity Surveyor will be able to provide you with an accurate depreciation schedule on your new purchase, once you've engaged them. We recommend that you do obtain the appropriate advice.
