A cost segregation study is an engineering-based tax analysis that reclassifies components of your property from the standard 27.5- or 39-year depreciation schedule into shorter 5-, 7-, or 15-year categories. This accelerates your depreciation deductions, generating significantly larger tax savings in the early years of property ownership rather than spreading them over decades.
