Qualified vs Non-Qualified Cost Segregation Providers
The quality of a cost segregation study is primarily determined by the qualifications and methodology of the provider. The qualified cost segregation provider market includes firms that use engineering-based methodology, conduct physical site inspections, and produce reports that satisfy IRS quality standards. It also includes firms that rely on percentage allocations, skip inspections, and produce reports that are less defensible under examination. The difference between these two categories is material and not always apparent from fee level or marketing.
This article describes what distinguishes qualified from non-qualified providers, the role of professional certification, and how to evaluate a provider before engaging. For the cost segregation fundamentals, the service landing page provides a complete overview of the study process and what to expect.
TL;DR - Key Takeaway
What Cost Segregation Qualifications Mean
Cost segregation qualifications refer to the expertise, credentials, methodology, and professional standards that distinguish providers capable of producing defensible studies from those that are not. No federal licensing requirement exists for cost segregation providers, which means the market includes a wide range of quality levels.
The IRS Audit Techniques Guide establishes an implicit qualification standard: the study should be prepared by someone with engineering or construction cost estimating expertise, using an engineering-based methodology, and producing a report that meets the 13 quality elements. A provider who cannot meet these standards is effectively not qualified to produce an ATG-compliant study.
ASCSP Certification and the Cost Segregation Professional Standard
The American Society of Cost Segregation Professionals administers the Certified Cost Segregation Professional designation. This credential requires passing a comprehensive examination covering tax law, engineering methodology, IRS compliance standards, and professional ethics. The ASCSP also publishes professional standards that member practitioners are expected to follow.
The ascsp certification is the most direct signal of professional commitment to ATG-aligned methodology. Not all qualified providers hold this certification, but it provides a verifiable benchmark for evaluating credentials. Providers who hold the CCSP designation have formally demonstrated proficiency in the technical and legal dimensions of cost segregation.
Engineering Credentials and ATG Alignment
The IRS Audit Techniques Guide expects that cost segregation studies are prepared by individuals with engineering or construction cost estimating expertise. This does not necessarily mean a licensed professional engineer, but it does mean that the individuals performing the component cost analysis have the technical background to evaluate the physical characteristics, function, and attachment of each component.
Providers who employ licensed engineers, certified cost estimators, or professionals with CCSP credentials are more likely to produce studies with the component-level analysis the ATG requires. Providers who rely solely on financial analysts, CPAs, or administrative staff without engineering support are generally less aligned with ATG standards.
Qualified vs Non-Qualified Provider Comparison
| Characteristic | Qualified Provider | Non-Qualified Provider |
|---|---|---|
| Methodology | Engineering-based, component-level analysis | Percentage allocation or residual method |
| Site inspection | Included as standard | Optional, virtual, or excluded |
| Staff credentials | Engineers or CCSP-holders | Financial or administrative staff |
| Report quality | Individual component descriptions with legal authority | Summary tables without component-level detail |
| ATG alignment | Meets most or all 13 quality elements | Typically missing several elements |
| Audit support | Available and clearly defined | Limited or not offered |
Red Flags of a Non-Qualified Cost Segregation Provider
Specific indicators that a provider may not meet qualification standards include:
- No site inspection included in the standard engagement
- Inability to explain the specific methodology used for component cost allocation
- No engineering staff or credentials disclosed
- Unusually low fees relative to the scope of the study
- Sample report shows summary allocation tables without individual component descriptions
- No mention of legal authority or IRS guidance in the report format
- Audit support not mentioned or disclaimed entirely
- Guarantee of specific results before reviewing the property
Questions to Ask When Evaluating Cost Segregation Providers
Before engaging a provider, the following questions directly assess the factors that determine study quality:
- Does the engagement include a physical site inspection, and who conducts it?
- What methodology is used for component cost allocation?
- What professional credentials do the analysts who perform the study hold?
- Is the CCSP designation held by any staff member working on the study?
- Can you provide a sample report from a similar property type?
- What is your audit support policy and is it included in the fee?
- How are indirect costs allocated among asset classes?
How to Review a Sample Report to Assess Provider Quality
A sample report is the most direct tool for evaluating a provider before engagement. When reviewing a sample, look for: individual component descriptions rather than summary tables, cited legal authority for each classification category, a methodology section explaining how costs were allocated, site inspection photographs, an indirect cost allocation schedule, and a depreciation schedule reconciliation.
A sample report that contains only summary percentages, lacks individual asset descriptions, and has no legal citations is a strong indicator that the provider does not meet ATG quality standards.
Table 2: Sample Report Quality Checklist
| Report Element | Present? | What to Look For |
|---|---|---|
| Property description | Required | Complete with size, type, construction date, use |
| Methodology section | Required | Specific description of cost allocation approach |
| Individual component listings | Required | Not just summary totals by asset class |
| Legal authority citations | Required | Specific statutes, regulations, and cases |
| Site inspection photographs | Required | Property photos and key component close-ups |
Cost Segregation Professional Standards
The ASCSP publishes professional standards for its members that formalize many of the ATG quality requirements. These standards cover: independence, competence, due care, scope of work, report content, and continuing professional education. Providers who follow these standards consistently produce studies that meet IRS expectations.
Non-ASCSP providers are not bound by these standards but should still adhere to the requirements established by the ATG. The practical difference is that ASCSP members have a formal accountability structure, while other providers operate on a self-imposed standard.
Cost vs Quality in Cost Segregation Provider Selection
Study fees in the market range widely. Lower fees generally reflect less thorough analysis, no site inspection, or template-based reporting. Higher fees do not guarantee quality, but the lowest fees in the market are often a signal that the methodology is not engineering-based.
A useful frame is to evaluate the fee relative to the expected tax benefit. A study that costs 20% more than the lowest quote but produces a defensible, ATG-aligned analysis is almost always the better economic decision. The risk of an IRS adjustment on a deficient study, with potential penalties and interest, far exceeds the fee differential.

Frequently Asked Questions
What qualifies a cost segregation provider?
A qualified cost segregation provider has engineering or construction cost estimating expertise combined with tax knowledge, uses an engineering-based methodology aligned with the IRS Audit Techniques Guide, conducts physical site inspections, and produces reports that satisfy the 13 quality elements the IRS uses to evaluate studies. The ASCSP CCSP designation is the primary professional credential in the field.
What is the difference between a qualified and non-qualified cost segregation provider?
Qualified providers use engineering-based methodology, conduct site inspections, and produce reports with individual component analysis and legal authority citations. Non-qualified providers may rely on rule-of-thumb percentages, skip site inspections, or produce reports that lack the component-level detail required for ATG compliance. The difference matters most during an IRS examination.
Does a cost segregation provider need to be a licensed engineer?
No federal law requires that a cost segregation provider be a licensed professional engineer. However, the IRS Audit Techniques Guide expects engineering-level expertise in construction cost estimating. Providers who employ licensed engineers or engineers with specialized cost estimating credentials are better positioned to produce defensible studies.
What is the ASCSP and why does it matter?
The American Society of Cost Segregation Professionals (ASCSP) is the professional organization for the cost segregation industry. It administers the Certified Cost Segregation Professional (CCSP) designation and publishes professional standards for member practitioners. Membership and certification signal a commitment to industry best practices and ATG-aligned methodology.
What questions should I ask when evaluating a cost segregation provider?
Key questions include: Does your engagement include a physical site inspection? What is your methodology for allocating costs to individual components? Do you have engineering credentials on staff? What professional certifications do your analysts hold? Can you provide a sample report? What is your audit support policy? These questions directly assess the factors that determine study defensibility.
Can a CPA perform a cost segregation study?
A CPA can manage the tax compliance aspects of implementing a cost segregation study, but the component cost allocation analysis requires engineering or construction cost estimating expertise that most CPAs do not have. Studies prepared solely by CPAs without engineering input are generally less defensible than those involving engineering analysis.
What is cost segregation professional standards compliance?
Professional standards compliance means the provider follows the written standards published by the ASCSP or similar professional bodies, which formalize the quality requirements from the IRS Audit Techniques Guide. Standards compliance covers methodology, documentation, site inspection procedures, report format, and ongoing education requirements.
How can I verify a cost segregation provider's credentials?
ASCSP membership and CCSP certification can be verified through the ASCSP website. Engineering credentials can be confirmed through state licensing boards. References from prior clients and their CPAs provide insight into audit experience and study quality. Requesting and reviewing a sample report is one of the most practical verification methods.
What red flags indicate a non-qualified cost segregation provider?
Red flags include: no site inspection offered, reliance on percentage allocations or industry averages without property-specific analysis, no engineering staff or credentials disclosed, unusually low fees that suggest minimal analysis, inability to explain methodology clearly, and no audit support policy. These factors indicate a provider that may not meet ATG quality standards.
Does a more expensive cost segregation provider always produce a better study?
Cost is not a reliable proxy for quality in cost segregation. Some high-quality providers are competitively priced, and some expensive providers may not meet quality standards. The best approach is to evaluate the provider based on methodology, credentials, site inspection policy, sample report quality, and professional certifications rather than on fee alone.
