Methodology

How we scored 25 firms.

Disclosed market guide. We operate Cost Seg Smart, one of the firms ranked here — see disclosure. No paid placements from the other 24 providers.

01
Pricing transparency
Is pricing on the website? Do public forums confirm it? Firms that require a sales call to quote were docked.
02
Methodology quality
Does the firm follow the IRS Audit Techniques Guide? RSMeans data? Engineering review vs. pure templating.
03
Turnaround & process
Hours vs. weeks. Site visit requirements. Remote-observation options. CPA workflow integration.
04
Property-type fit
A firm that excels at a 12-unit apartment complex may be mediocre on a $400K SFR. Scoring is per-category.
Questions

Things people ask us.

How much should a cost segregation study actually cost?
For a standard residential rental or STR under $2M, anything over ~$2,000 is paying for brand name, not study quality. The firms charging $5,000–$15,000 use the same RSMeans cost data and IRS methodology as the firms charging $495–$1,495. Your CPA files the same forms either way. Premium pricing makes sense for complex commercial ($3M+), mixed-use buildings, and industrial facilities with specialized equipment.
Does the IRS require a site visit?
No. The IRS ATG recommends "detailed engineering" — component-level cost allocation using recognized databases. That does not require a person physically entering your property. For standard residential properties, remote-data-driven approaches using assessor records, satellite imagery, and cost databases can be sufficient. For a manufacturing plant or hospital with specialized equipment, a site visit adds genuine value.
Can I do a study on a property I bought years ago?
Yes. Your CPA files IRS Form 3115 (change of accounting method) and you take all the missed depreciation in the current tax year — no amended returns required. If you bought a rental in 2015 and never did a study, you can claim a decade of missed accelerated depreciation on this year's return in one shot.
Is 100% bonus depreciation still available in 2026?
Yes. The One Big Beautiful Bill Act (signed July 2025) permanently restored 100% bonus depreciation for qualifying property placed in service after January 19, 2025. All your 5-, 7-, and 15-year components can be fully deducted in year one.
What's the difference between a "full engineering" study and an automated report?
Full engineering: human engineers review your property (sometimes on-site, sometimes via video) and classify each component by hand. Automated: same cost databases, same IRS methodology, software does the analysis. The output is functionally identical for standard properties. The difference starts mattering for complex commercial where human judgment on edge cases has real value.
Is cheapcostseg.com affiliated with any provider?
Yes — disclosure. cheapcostseg.com is operated by the team behind costsegsmart.com, a cost segregation provider included in these rankings. Our perspective is not independent. Treat this as a disclosed market guide created by a market participant, not a neutral publisher. Other firms listed are separate companies and did not pay for placement. Rankings reflect our own research — you should do your own due diligence before choosing a provider.
