A cost segregation study is an engineering-based analysis that identifies property components qualifying for accelerated depreciation. Instead of depreciating your entire building over 27.5 or 39 years, we reclassify assets like HVAC systems, electrical upgrades, and site improvements into 5, 7, or 15-year schedules. This front-loads your deductions, reducing taxable income and increasing cash flow in year one—often by six figures for properties over $1 million.
