Cost segregation companies near you.

Cost Seg Smart serves every US state — there's no geographic limit because our engineered methodology doesn't require an on-site visit. The IRS Cost Segregation Audit Techniques Guide (Pub. 5653) does not mandate physical inspection; component classification requires defensible cost data (industry-standard 2026 construction cost data) and engineering judgment, not someone walking the property. We have dedicated landing pages for 95+ specific markets across 35 states.

No. A traditional engineering firm that does send someone on-site can be the right fit for $5M+ commercial properties with specialty assets (medical office MEP, manufacturing systems, hospitality FF&E density). For residential rentals, short-term rentals, small multifamily, and small commercial under $5M, a structured-data approach using county assessor records, RentCast, satellite imagery, and industry-standard cost data produce the same MACRS classification under Rev. Proc. 87-56 at 1/10th the cost and 1/40th the turnaround.

The largest engineer-led firms (Madison SPECS, Engineered Tax Services, Capstan Tax Strategies) serve all 50 states from regional engineering hubs. Mid-tier firms (ELB Consulting, CSSI, Bedford Cost Segregation, McGuire Sponsel) operate nationally with regional concentrations. Remote-first firms (Cost Seg Smart, R.E. Cost Seg, Remote Cost Seg, Expert Cost Seg) serve every state without geographic constraints because the methodology is structured-data based. The IRS treats all of them under the same Pub. 5653 framework — provider location is not part of the audit-defense evaluation.

Five questions independent of geography: (1) Does the report include component-level industry-standard construction cost basis citations and MACRS classification per Rev. Proc. 87-56? (2) Is the report prepared and reviewed by a qualified preparer or engineer per IRS Pub 5653? (3) Does it include Form 3115 §481(a) documentation for prior-year lookback studies? (4) Does the firm respond to IRS examinations through your CPA at no additional charge? (5) Is there a refund or revision guarantee if your CPA can't use the report? Any credible firm — local or remote — should answer yes to (1) through (4).

Yes — every US city. We have dedicated landing pages with market-specific tax notes for major investor markets (Phoenix, Austin, Nashville, Miami, Denver, Dallas, Los Angeles, San Diego, Orlando, Tampa, Atlanta, and many more — see the directory below). For markets without a dedicated page, the order form accepts any US address; the engine pulls county assessor data for that specific property regardless of city.

Many states decouple from federal §168(k) bonus depreciation — Illinois, California, New York, New Jersey, and others require state-level addback adjustments. This affects your state return, not the federal Year-1 deduction. The federal cost-segregation benefit is permanent under OBBBA (Pub. L. 119-21); state treatment varies. Verify with your CPA before relying on bonus depreciation for state planning purposes.
