ASCSP Membership Levels Matter

ASCSP membership and certification represent different levels of professional involvement and credentialing. Understanding the distinction helps professionals identify their next step and helps taxpayers make more informed decisions when selecting a provider.

Associate

An entry point into the ASCSP community for individuals and firms building their involvement in cost segregation and the professional network around it.

Associate is not a technical or certified designation.

Member

Practicing cost segregation professionals who participate in the Society, agree to its standards and code of ethics, and have access to member education and resources.

Members are listed in the ASCSP Member Directory. Membership alone does not indicate certification.

Certified Member

CERTIFIED COST SEGREGATION PROFESSIONAL · CCSP

Certified Members have completed ASCSP’s certification process and hold the CCSP designation. Certification reflects demonstrated knowledge of cost segregation methodology and a commitment to the Society’s professional standards and code of ethics.

CCSP is the only ASCSP designation that indicates certification.

WHY CERTIFICATION MATTERS

Not all cost segregation studies are created equal.

The Certified Cost Segregation Professional (CCSP) designation identifies professionals who have demonstrated advanced technical knowledge, industry experience, and a commitment to the highest standards of practice.

For taxpayers and CPAs, working with a CCSP means partnering with a professional who understands the complexities of tax law, engineering-based asset classification, documentation requirements, and audit defensibility. When significant tax savings and compliance are on the line, a CCSP provides the expertise, credibility, and confidence needed to help ensure your cost segregation study is completed accurately, thoroughly, and in accordance with industry best practices.

ABOUT ASCSP

Setting the Standard for the Cost Segregation Profession

The American Society of Cost Segregation Professionals (ASCSP) is the professional association for the engineers, accountants, and tax professionals who perform cost segregation studies. Founded in 2006, the Society defines what sound practice looks like in a field where methods and experience vary widely from one provider to the next.


ASCSP publishes minimum quality standards for cost segregation studies, delivers technical education and continuing professional education, and administers the Certified Cost Segregation Professional (CCSP) credential. Every member agrees to the Society’s code of ethics.


Together, these give practitioners a shared framework for consistent work and give taxpayers, CPAs, and advisors a practical way to recognize qualified professionals.

ASCSP helps taxpayers, property owners, accountants, and advisors understand professional credentials and connect with ASCSP professionals through the Member Directory.

The quality of a cost segregation study depends on the methodology, documentation, and experience behind it. Knowing whether a provider is an ASCSP Member or a Certified Cost Segregation Professional gives you a clearer basis for evaluating qualifications before you engage.

EDUCATION

What Is Cost Segregation?

Cost segregation is an engineering-based analysis that identifies the components of a commercial real estate property and classifies them for tax depreciation purposes. Instead of depreciating an entire building over 27.5 or 39 years, a cost segregation study assigns qualifying building components and land improvements to shorter recovery periods.

For property owners who have purchased, constructed, or renovated commercial property, a well-prepared study can accelerate depreciation deductions. Because the results depend on the quality of the analysis, the experience and methodology of the cost segregation professionals performing the work matter.

The Society's published standards and code of ethics are the foundation of every ASCSP designation. They give members a shared definition of sound practice and give the public a reason to trust the credential.
