Why CSI
Built on decades of specialized cost segregation experience
Cost Segregation Strategies-Cost Segregation Initiatives is not a firm that rushed into this space when the OBBBA 100%bonus depreciation headlines made it fashionable. We have been doing this work since before most of the market knew what cost segregation was. Nor are we a CPA firm competing for new clients.
Our studies are known and respected by the IRS.
CSS-CSI provides studies that hold up to the IRS, to trusted tax professionals, and to your bottom line. Our clients are commercial property owners, real estate developers, and the CPAs and brokers who serve them. They come to us through referrals, because the work speaks for itself.
What We Do
Cost Segregation Studies
We identify and document building components that can legally be reclassified for accelerated depreciation under IRS guidelines, creating front-loaded tax deductions and vital cash flow.
Includes
Component-level classification
Depreciation acceleration
CPA-ready documentation
Complete System Analysis
We don't just take the low-hanging 5-year fruit. We document roofing, HVAC, plumbing, electrical, structural framing, flooring, land improvements, and specialty buildouts, so you can capture that depreciation when replacements are needed.
Includes
Major building systems
Defensible asset values
Partial disposition support
Certified, IRS-Compliant Reports
Every study is performed by Certified Cost Segregation Professionals and prepared in accordance with IRS guidelines, with the engineering and tax analysis to support every classification.
Includes
No junior partners or off-shore consultants
CCSP-led analysis
Detailed documentation
Full Audit Support
If the IRS ever questions a CSS-CSI study, we defend it at no additional cost. A study that cannot be defended is not worth the paper it is printed on. We believe you shouldn’t have to pay extra for that.
