Matthew Gigantelli's South Dakota Analysis
ASCSP Member M009-25 · Lead Cost Segregation Engineer
"South Dakota's zero income tax makes cost segregation purely a federal play — clean and simple. Sioux Falls has emerged as a significant financial services hub (particularly for trust and banking companies) with quality multi-family and commercial development. Rapid City's tourism market (Mount Rushmore, Black Hills) produces hospitality properties with strong reclassification rates. The state's growing population and business-friendly environment are driving new construction that creates ideal cost seg candidates."

How Cost Segregation Works in South Dakota
Cost segregation is an IRS-approved tax strategy that reclassifies components of your South Dakota 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 South Dakota property owners, this means turning a $1.6M commercial property into $26,000 - $66,000 of first-year tax savings instead of waiting decades for the same deduction.
