Matthew Gigantelli's Montana Analysis
ASCSP Member M009-25 · Lead Cost Segregation Engineer
"Montana has experienced explosive growth, particularly in the Bozeman and Kalispell/Whitefish corridors. Full federal conformity and a declining state rate (5.65% in 2026, heading to 5.4%) make cost segregation straightforward. The resort and STR market near Yellowstone and Glacier National Parks produces premium reclassification rates due to high-end FF&E and finishes. Montana's no-sales-tax status attracts investment, and the state's high median home prices reflect the quality of new construction."

How Cost Segregation Works in Montana
Cost segregation is an IRS-approved tax strategy that reclassifies components of your Montana 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 Montana property owners, this means turning a $2.8M commercial property into $42,000 - $110,000 of first-year tax savings instead of waiting decades for the same deduction.
