Matthew Gigantelli's Oklahoma Analysis
ASCSP Member M009-25 · Lead Cost Segregation Engineer
"Oklahoma independently provides 100% bonus depreciation at the state level and has established a trigger mechanism to phase out its income tax entirely over time. For cost segregation, this means the strongest possible state conformity today. Oklahoma City and Tulsa both have diverse commercial markets — energy sector office properties, logistics/distribution centers, and a growing multi-family market. Lower property values mean studies cost less with faster payback, making cost seg accessible for smaller properties."

How Cost Segregation Works in Oklahoma
Cost segregation is an IRS-approved tax strategy that reclassifies components of your Oklahoma 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 Oklahoma property owners, this means turning a $1.4M commercial property into $22,000 - $58,000 of first-year tax savings instead of waiting decades for the same deduction.
