Cost segregation allows the taxpayer to identify property that is part of an asset class with a shorter recovery period and take the appropriate depreciation. This leads to larger deductions in early years of the property.
Property such as a commercial building or a rental property have longer property lives and recovery periods than tangible property. Residential rental property has a property life of 27.5 years, while nonresidential real property has a property life of 39 years.
Cost Segregation Study
▪ For property valued at $500K, a cost segregation study is required.
▪ Experts evaluate the property and break down what parts of the property are “structural components” and what parts could be considered “Section 1245 Property.”
▪ The “Section 1245 Property” is then given the appropriate asset class as determined by the IRS, with the corresponding recovery period.
▪ The evaluation is compiled with an explanation of the methodology used.
▪ Property that qualifies for a shorter recovery period can be depreciated at an accelerated pace, leading to larger deductions in earlier years!







Implementation
▪ Schedule a Cost Segregation Study if necessary
▪ Bonus depreciation (if qualified) is the default method under current law
