Our Commercial Services

Depreciation Schedules

A thorough and initial commercial depreciation schedule should be completed upon construction or acquisition of any commercial property. It enables owners to maintain a commercial tax depreciation schedule, to maximize their tax returns. As Quantity Surveyors, we identify and estimate all eligible depreciating assets - including capital works and plant and equipment assets! Our AIQS and RICS qualified Quantity Surveyors conduct assessments documenting evidence in accordance with ATO substantiation requirements.

Asset Registers

Our detailed asset registers are compiled through a comprehensive survey carried out by our Quantity  Surveyors. A detailed asset register will provide you with a full list of assets, which in turn will assist with compliance, audits , sinking funds, asset planning and ongoing commercial tax depreciation.

Balancing Adjustments

Often overlooked are the deductions you may be entitled to upon demolition of an asset. Whether it is capital works or a depreciating asset, the un-deducted value (written down value) of the asset can be claimed in the year of demolition.

Tenant Abandonment

Upon lease expiry the capital works component of the tenants fit out reverts to the landlord if the fit out is not demolished. Our assessment identifies the eligible capital works component.

Took a whilst to organise the survey this was partly due to tenant not giving access to the survey. Pleased with the return and will use again.
