Why cost segregation works in Washington
Washington has no state income tax. Seattle's tech economy drives premium-basis multifamily and Class A office, while Eastern Washington adds agricultural and industrial cost seg work. An engineering-based cost segregation study reclassifies components of your Washington property from 27.5- or 39-year real property into 5-, 7-, and 15-year MACRS class lives. Under the One Big Beautiful Bill Act (OBBBA), 100% bonus depreciation has been restored for qualifying property acquired and placed in service after January 19, 2025 — meaning every dollar of accelerated property identified can be deducted in year one.
