Your residential study
One-time base price per qualifying residential property. No subscription. Optional services are priced separately.
Complete the property questionnaire online. Purpose-built software prepares the analysis, and cost segregation engineers review and can correct the study before delivery. Basis does not use AI for engineering analysis, component classification, or recovery-period determinations.
- Property-specific component allocations and supporting methodology.
- Depreciation schedules for your tax professional to evaluate.
- Professional review before the report is delivered.
- Three years of limited support for questions about the delivered report.

What is outside the base price
Tax-return preparation, Form 3115 preparation, IRS representation, and separate prior-year or post-purchase renovation services are not included in the base study price. A support schedule is not the same as preparing or filing a tax form.
Additional services, unusual property facts, and portfolio needs require their own scope. Review available options before paying. For five or more properties, ask about portfolio pricing.
Compare the scope behind the fee
A lower fee does not by itself mean a weaker report, and a higher fee does not guarantee more useful deductions. Compare investigation, owner effort, review, documentation, and support.
| Service | Price information | What to check |
|---|---|---|
| Online services with automated analysis | Some published offers start at $495. | Property limits, who verifies inputs, and whether a person reviews every report. |

| Custom engineering engagement | Quoted for the assignment | Site work, measurements, complex systems, travel, and specialist investigation. |
The $495 starting example is a published Cost Seg Smart offer, checked September 11, 2026. Prices increase with eligibility and scope; it is not a quote for every property. Our provider comparison explains the differences and links to the source offers.
Questions before paying
Can I use the estimate without buying a report?
Yes. The estimate is free and does not require an account to start. It is preliminary information, not a completed cost segregation study.
Is a study always worth the fee?
No. Land value, eligible components, your ability to use deductions, expected holding period, and additional tax-preparation costs can change the result. Discuss those facts with your tax professional before ordering.
Does report support include an IRS representative?
No. Included support addresses the delivered report and its methodology or classifications. It does not include representation, tax-return preparation, or Form 3115 preparation.
Start with your property
Use the free estimate to explore potential accelerated depreciation, then ask your tax professional whether the deductions would help in your situation. There is no account or payment required to start.
