How to Choose the Best Cost Segregation Company
Compare cost segregation companies by study evidence, fees, qualifications, and CPA support. Use Stratum’s buyer checklist and provider comparison worksheet.
The best cost segregation company for your property should provide a supported component analysis, a clear scope and fee, and a report your tax preparer can use. If you are comparing cost seg companies, start with the property and the evidence behind the proposal. The largest preliminary deduction is not, by itself, a measure of report quality.
About this comparison: Stratum is a cost segregation provider. This is our buyer’s framework, not an independent league table. We have not audited competitors’ reports, measured their client outcomes, or assigned performance scores. Public offerings below were checked on September 27, 2026; obtain current written proposals before making a decision.
Compare the service you are actually buying
A software-generated report, a property-specific study, and a study bundled with tax-return work are different offerings. A company may sell more than one. Ask which offering the quote covers and how it addresses your property’s complexity. Use the same acquisition documents and improvement facts when requesting proposals so the assumptions can be compared.
| Provider | Public information to review | Question for your proposal |
|---|---|---|
| Stratum Cost Segregation | Our study process and study standards describe property-level analysis and coordination with AE Tax Advisors. | What records, component schedules, inspection approach, and preparer follow-up are included for my property? |
| KBKG | KBKG’s website presents tax consulting services and links to its cost segregation software offering. | Which offering is being quoted, what property criteria apply, and how much professional review or follow-up does it include? |
| Engineered Tax Services | ETS’s website describes engineering-based cost segregation among its specialty tax services. | How does the proposed study scope fit this asset, and which related services are included or separately engaged? |
These links let you inspect each provider’s own description. They do not establish that a provider is better, cheaper, faster, or more defensible than another. Compare the written engagement and supporting evidence rather than assuming that a company name identifies a single standardized product.
A checklist for comparing cost segregation companies
| Compare | Ask for | Why it matters |
|---|---|---|
| Preparers and review | The people responsible, relevant qualifications, and review process | You need to know who develops and stands behind the analysis. |
| Property evidence | Inspection scope, available plans, photographs, and how missing information is handled | The proposed method should fit the actual building and records. |
| Cost reconciliation | A path from acquisition and improvement records to the analyzed basis | A furnishing allowance or duplicate invoice can otherwise distort the cost pool. |
| Report detail | A redacted sample showing components, assumptions, methodology, and classification support | A total projected deduction does not show how conclusions were reached. |
| Fees and exclusions | The written fee, revision terms, record assumptions, and separately billed work | Quotes are only comparable when their deliverables are comparable. |
| CPA handoff | Delivery format and responsibility for resolving implementation questions | The property study and the return-filing decision must connect. |
| Examination support | Who responds, what assistance is included, and any extra fees | A general promise of audit protection does not define contractual support. |
| Timing | A schedule tied to complete records and a process for exceptions | The provider should explain what can delay a report before a filing deadline. |

Match the provider to the property
For an STR, reconcile furnishings, guest amenities, personal-use periods, and later improvements. Our STR-specific provider guide expands those questions. For a commercial or mixed-use project, ask for experience with comparable construction and the relevant ownership arrangements; the property-type guides outline scoping considerations.
For an older property, bring the existing asset schedule and ask the return preparer how a new study would be implemented. For a recently built property, collect final construction costs and owner-supplied items. Choosing a company before assembling those facts can leave you comparing estimates based on different properties in all but name.
Evaluate the economics with your preparer
A study fee buys an analysis, not a guaranteed tax result. Ask the preparer to consider whether the owner can use deductions currently, the expected holding period, state treatment, and potential consequences on sale. A proposal can be technically detailed yet provide limited immediate benefit for a particular owner. Read when a study may not fit before assuming every property should proceed.
The IRS Cost Segregation Audit Techniques Guide is a useful reference for discussing study methodology and documentation. It is examiner guidance, not an IRS certification of a provider or a promise that a report will be accepted. Publication 946 provides broader depreciation guidance for the preparer’s review.
Where Stratum fits in your comparison
Stratum’s site focuses on property-level cost segregation, with a substantial set of STR and rental-property resources. Discovery calls are scheduled through AE Tax Advisors, and the owner’s return preparer evaluates implementation. Compare our pricing information, process, and study standards with the same written checklist you use for other companies.
For a property-specific discussion, prepare the closing documents, existing depreciation schedule, furnishing records, and improvement history. The study preparation planner builds a checklist without requesting income or account information. Use the market directory to find local planning resources; a market page represents service coverage, not a local office or a local ranking.
Questions before hiring
Which cost segregation company is best?
There is no evidence here that establishes one universal winner. The best fit depends on your property, available records, required deliverables, fee, and support needs. Obtain comparable proposals and have the intended return preparer review the scope.
Is the cheapest cost seg report the best value?
Price is one input. A lower fee may cover a different service, while a higher fee does not prove a better result. Compare the actual evidence, review, exclusions, and follow-up obligations.
Does an engineering label guarantee IRS acceptance?
No. Ask how the property is documented, how costs are reconciled, and how classifications are supported. A marketing label cannot guarantee an examination outcome.
Should I choose a local company?
Ask how the provider will gather the property evidence and coordinate with the preparer. A local address alone does not demonstrate the quality of a study, and nationwide service does not remove the need for property-specific documentation.
