Matthew Gigantelli's Mississippi Analysis
ASCSP Member M009-25 · Lead Cost Segregation Engineer
"Mississippi independently provides 100% bonus depreciation at the state level and is phasing its income tax rate down from 4% toward eventual elimination. For cost segregation, this means clean dual-benefit treatment today with a declining state component over time. The Gulf Coast casino and hospitality market (Gulfport-Biloxi) produces excellent reclassification rates, and the state's lower property values mean studies cost less with faster payback. I recommend cost seg for any Mississippi commercial property with a basis above $250K."

How Cost Segregation Works in Mississippi
Cost segregation is an IRS-approved tax strategy that reclassifies components of your Mississippi 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 Mississippi property owners, this means turning a $1.1M commercial property into $18,000 - $46,000 of first-year tax savings instead of waiting decades for the same deduction.
