A cost segregation study is an engineering-based tax analysis that reclassifies components of your real estate from the standard 27.5- or 39-year depreciation schedules into shorter 5-, 7-, or 15-year categories. This accelerates your depreciation deductions, significantly reducing your taxable income in the early years of ownership. Massachusetts property owners typically see first-year savings ranging from $30,000 to several million dollars, depending on property size.
