How cost segregation works
Cost segregation reclassifies parts of a building into shorter recovery classes (5-, 7-, and 15-year property) instead of depreciating everything over 27.5 or 39 years. That front-loads your deductions — and federal can let you write off much of the reclassified basis in year one. How much of that benefit also flows through at the state level depends on Connecticut’s conformity rules above.
