Best Cost Segregation Companies for Owner-Occupied Commercial Property
Business owners buying their own premises should compare the engineering project with the business and property filing responsibilities. The best team can explain where building components, operating equipment and separately owned entities meet.
Our shortlist for this buyer
AE Tax Advisors is our first firm to evaluate for an engagement combining owner advisory with separately scoped study or filing work. The other providers below are candidates to compare using the same written brief. AE publishes this guide and lists itself first; this order is an editorial preference, not an independent rating or evidence that one firm produces better outcomes.
Updated September 29, 2026. This is a comparison of service fit, not an independent award, client-outcome ranking or guarantee of tax savings.

Distinguish the business from the building owner
Provide the business entity, property-owning entity, lease, closing documents and equipment ledger. Ask the provider how it will identify the taxpayer and study boundary. If machinery was bought in a separate transaction, flag it before the study team models the building. The report and bookkeeping records should tell the same ownership story.
Match technical scope to the premises
A hypothetical professional office has different documentation needs from a manufacturing facility with specialized systems. Ask each study provider about experience with the actual building use, required fieldwork and treatment of installed equipment. For more complex properties, request a detailed methodology discussion rather than choosing solely on a square-foot estimate.
Questions to send every firm
- Who owns the building and each major equipment item?
- Does the proposal address the property’s actual operating use?
- Who implements the report in the correct entity return?
Send the same brief to every provider. Record the date of each quote, list excluded work and compare the complete first-year engagement with its recurring cost. Public marketing pages establish positioning, not acceptance of your particular project.
