Matthew Gigantelli's Idaho Analysis
ASCSP Member M009-25 · Lead Cost Segregation Engineer
"Idaho has been one of the fastest-growing states in the country, and Boise's commercial real estate market has matured significantly. Full conformity with bonus depreciation at a 5.3% flat state rate means clean, dual-benefit cost segregation. The Treasure Valley (Boise metro) has seen massive multi-family and retail development, while Coeur d'Alene's resort and STR market produces premium reclassification rates. Newer construction throughout the state means more qualifying personal property components."

How Cost Segregation Works in Idaho
Cost segregation is an IRS-approved tax strategy that reclassifies components of your Idaho property from the standard 39-year (commercial) or 27.5-year (residential) depreciation schedule to shorter 5, 7, and 15-year recovery periods. With 100% bonus depreciation restored under the One Big Beautiful Bill Act, these reclassified components can be fully depreciated in year one.
For Idaho property owners, this means turning a $2.7M commercial property into $40,000 - $105,000 of first-year tax savings instead of waiting decades for the same deduction.
