Why This Matters for Operators

Cost segregation reclassifies parts of a building from the default 39- or 27.5-year depreciation life into 5- and 15-year classes, pulling depreciation forward into the years an owner is most likely to need it. The catch has always been the sales process: quoting requires an engineer's time before the buyer knows whether the study pays for itself.

The MCP turns the feasibility question into one tool call. A $750,000 short-term rental at a 37% bracket returns a $995 study cost against an estimated $184,500 year-one deduction — $68,265 in year-one tax savings, a 69x ROI on the fee. The quote is read-only, idempotent, and free to call.

Business Relevance

  • CPAs price feasibility for clients before committing to studies
  • Fractional CFOs surface tax-savings opportunities to every real estate client
  • Real estate investors check whether a property justifies a study before buying
  • Tax-software workflows embed study pricing and checkout directly

Integration with CorpusIQ

Cost Seg Smart pairs with the CorpusIQ accounting stack: QuickBooks holds the fixed-asset schedule, Stripe shows the payment rail the checkout link runs through, and Cost Seg Smart MCP supplies the study economics. A composed workflow quotes a portfolio property, logs the estimated year-one deduction, and files the paid invoice against the QuickBooks fixed-asset accounts.

Limitations

  • Estimates based on industry-standard construction cost data; actual results vary with property condition and finishes — not tax advice
  • US properties only
  • Study pricing is commercial (from $995)
  • Brand new — no track record yet
