A cost segregation study is an engineering-based tax analysis that reclassifies components of your real property such as flooring, lighting, landscaping, and specialty equipment into shorter depreciation categories of 5, 7, or 15 years, instead of the standard 27.5 or 39 years. This accelerates your depreciation deductions, significantly reducing your taxable income in the early years of ownership and freeing up cash for reinvestment.
