A cost segregation study is an engineering-based tax analysis that reclassifies components of your real property like flooring, lighting, and land improvements from 27.5- or 39-year depreciation schedules into shorter 5-, 7-, or 15-year schedules. This accelerates your depreciation deductions, reducing your taxable income significantly in the early years of ownership. Most clients see a 10–25:1 ROI on the cost of the study itself.
