Frequently Asked Questions
Why do I need a Quantity Surveyor?
A Quantity Surveyor is one of the only profession approved by the ATO to identify every allowable deduction on your investment property, which accountants cannot do alone. Our reports help you maximise your tax return while ensuring your depreciation claims are accurate and ATO-compliant.
What is property depreciation?
Property depreciation refers to the decline in value of a building and its assets over time. Eligible investors may be able to claim depreciation deductions for qualifying building works and assets used to produce assessable income. Any tax or cash-flow benefit depends on individual circumstances.
Is it worth getting a property depreciation schedule?
A property depreciation schedule may help identify eligible deductions for your accountant to review. Whether it is worthwhile depends on the potential deductions and the report cost. The amount and duration of any deductions depend on the property and your circumstances, and tax savings are not guaranteed.
What does a Quantity Surveyor do?
A quantity surveyor is a construction professional who specialises in estimating and managing costs related to buildings and property. They prepare detailed assessments that help property investors understand values, reduce costs where possible and ensure compliance with governing bodies. They are one of the few professions who can prepare tax depreciation schedules due to their skillset.
