Cost Segregation in New Haven, Connecticut

By Zawwad Ul Sami, Founder, WeCostSegPublished: 2026-05-14Last updated: 2026-05-14

Cost segregation in New Haven, Connecticut follows the same federal IRC Section 168(k) rules as anywhere in the United States: reclassify a portion of basis from 27.5 or 39 year recovery into 5, 7, and 15 year buckets so 100% bonus depreciation under OBBBA applies in year one. State-level treatment depends on Connecticut conformity. Local market color: Yale-anchored economy. Steady graduate-student and medical-resident rental demand.

The New Haven market in one paragraph

Yale-anchored economy. Steady graduate-student and medical-resident rental demand. Top property types in the New Haven market: Multifamily, Single-Family Rental. County: New Haven. Each property type carries a different cost segregation reclassification profile based on its component mix. STRs and hotels reclassify more aggressively (25-30% typical) because of the FF&E density. Single-family rentals reclassify in the 18-22% band. Multifamily lands in 20-25%.

How Connecticut treats your federal cost seg deduction

Connecticut is fully decoupled from federal bonus depreciation. The state benefit is excluded. The federal benefit remains.

For New Haven investors, this determines whether the cost seg benefit is purely federal or stacks with state-level savings. Coordinate with your CPA on the state addback (if applicable) before finalizing the engagement.

Worked example: a $750K New Haven property

On a $750K depreciable basis residential rental in New Haven acquired with a binding contract on or after January 20, 2025: cost segregation typically reclassifies 20-25% into 5-year personal property and 8-10% into 15-year land improvements. Combined reclassification: roughly $187K to $225K.

  • 5-year reclassification (20%): ~$150,000
  • 15-year reclassification (8%): ~$60,000
  • First-year deduction at 100% bonus: ~$210,000
  • Estimated federal tax savings at 32% marginal: ~$67,200
  • Estimated federal tax savings at 37% top marginal: ~$77,700

Whether the loss is usable this year depends on the New Haven investor's tax profile. REPS qualification, STR loophole, or other passive income unlock immediate offset against W-2 or active income. Without one of those, the loss suspends as a passive activity loss under IRC Section 469(b) and carries forward until released.
