Matthew Gigantelli's Oregon Analysis

ASCSP Member M009-25 · Lead Cost Segregation Engineer

"Oregon is one of the most compelling states for cost segregation because of its full federal conformity combined with a top state rate of 9.9% — the fourth highest in the nation. This means high-income investors get nearly 47 cents of combined federal+state savings per dollar of accelerated depreciation. Portland's industrial and multi-family markets are substantial, while Bend's resort and STR market produces premium reclassification rates. No sales tax keeps construction costs lower, but depreciable basis remains strong."

How Cost Segregation Works in Oregon

Cost segregation is an IRS-approved tax strategy that reclassifies components of your Oregon 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 Oregon property owners, this means turning a $3.4M commercial property into $48,000 - $135,000 of first-year tax savings instead of waiting decades for the same deduction.
