Matthew Gigantelli's Mississippi Analysis
ASCSP Member M009-25 · Lead Cost Segregation Engineer
"Mississippi independently allows full expensing 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."

Bonus Depreciation Status
Mississippi allows full expensing at the state level independently of federal policy, so the state deduction holds regardless of federal changes. The federal rate branches on acquisition date: 100% for qualified property acquired and placed in service after January 19, 2025, and 40% for property acquired before January 20, 2025 and placed in service in 2025. The state is also phasing down its income tax rate toward eventual elimination.
100% Bonus Depreciation Restored (July 2025): The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for qualifying assets placed in service after 2022. This dramatically increases cost segregation ROI in Mississippi.

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 under the One Big Beautiful Bill Act, which applies to qualified property acquired and placed in service after January 19, 2025, these reclassified components can be fully depreciated in year one. Property acquired before January 20, 2025 and placed in service in 2025 is limited to 40%.
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.

Mississippi Cost Segregation FAQs
How much does a cost segregation study cost in Mississippi?
The market average across providers in Mississippi is $2,000 - $4,500, depending on property size, complexity, and type. That is a state market average, not our quote. At Modern CFO the fee is set by the engineering work your property requires, not by what the property is worth: $1,200 to $2,500 for residential and small property (single-family, condo, short-term rental, 2 to 4 unit multifamily), $2,500 to $6,000 for standard commercial, and $6,000 to $12,000 for large and complex assets, with complex properties quoted individually above that. Every study in every band is engineering-based and signed by a licensed engineer. The average ROI is 6:1 to 10:1, meaning the study pays for itself many times over in first-year tax savings alone.
Does Mississippi conform to federal bonus depreciation?
