A cost segregation study identifies and reclassifies personal property assets to shorten the depreciation time for taxation purposes, which reduces current income tax obligations and results in increased cash flow. The primary goal of a cost segregation study is to identify all construction-related costs that can be depreciated over a shorter tax life (typically 5, 7 and 15 years) than the building (39 years for non-residential real property). Personal property assets found in a cost segregation study generally include items that are affixed to the building but do not relate to the overall operation and maintenance of the building.
