CostSegRx Review (2026)
CostSegRx is a Boutique cost segregation firm offering IRS-compliant cost segregation studies. Every credible study — CostSegRx's included — must classify components into MACRS 5, 7, 15, 27.5, and 39-year recovery periods under Rev. Proc. 87-56 and follow the engineering-based approach set out in the IRS Cost Segregation Audit Techniques Guide (Pub 5653), distinguishing §1245 personal property from §1250 real property before §168(k) bonus depreciation and Form 3115 (§481(a) catch-up) come into play. Published turnaround is not published, and pricing is published for at least one service line. What differs across providers is price, site-visit requirement, and audit-defense scope — not the underlying framework.
Editorial note: Cost Segregation Reviews is operated by Cost Seg Smart, which appears as one of the providers evaluated on this site. Public-facing data only — pricing, methodology, and credentials reflect what each provider publishes. Facts on this page verified September 6, 2026.
