Matthew Gigantelli's Connecticut Analysis
ASCSP Member M009-25 · Lead Cost Segregation Engineer
"Connecticut's non-conformity with bonus depreciation requires careful dual-schedule planning, but the numbers still work extremely well. With a top state rate of 6.99% and some of the highest property values in the Northeast, the federal benefit alone justifies cost segregation on virtually any commercial property above $500K in basis. The Stamford/Greenwich corridor — with its concentration of financial services and hedge fund office properties — produces premium reclassification rates due to high-end interior finishes."

How Cost Segregation Works in Connecticut
Cost segregation is an IRS-approved tax strategy that reclassifies components of your Connecticut 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 Connecticut property owners, this means turning a $3.6M commercial property into $52,000 - $140,000 of first-year tax savings instead of waiting decades for the same deduction.
