The Ambrose Group Review (2026)
The Ambrose Group is a Boutique cost segregation firm offering IRS-compliant cost segregation studies. Every credible study — The Ambrose Group'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 not published on the firm's site. What differs across providers is price, site-visit requirement, and audit-defense scope — not the underlying framework.
