Matthew Gigantelli's Delaware Analysis
ASCSP Member M009-25 · Lead Cost Segregation Engineer
"Delaware's full conformity with bonus depreciation and its status as a corporate-friendly state make it a clean market for cost segregation. Wilmington's financial district has significant Class A office and mixed-use properties, while the Rehoboth Beach corridor offers strong STR and hospitality opportunities. The state's top rate of 6.6% provides meaningful additional state savings on top of federal benefits. No sales tax in Delaware also means construction costs are lower, but the depreciable basis remains strong."

How Cost Segregation Works in Delaware
Cost segregation is an IRS-approved tax strategy that reclassifies components of your Delaware 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 Delaware property owners, this means turning a $2.4M commercial property into $35,000 - $90,000 of first-year tax savings instead of waiting decades for the same deduction.
