CSSI Services Information

CSSI specializes in engineering-based tax consulting for commercial property owners and businesses. Since 2003, we've completed over 60,000 studies nationwide, helping clients reduce tax liability and improve cash flow through proven strategies. We're best known for cost segregation, but our engineering-based approach applies across three distinct tax strategies. Cost segregation accelerates depreciation and unlocks immediate cash flow for property owners. 179D energy deductions provide building owners and designers up to $5.81 per square foot on qualifying projects. And R&D tax credits identify and document qualifying activities that generate dollar-for-dollar tax reductions for businesses investing in innovation. Our approach is the same across every service: detailed engineering analysis combined with deep tax expertise. Every study is built to meet IRS standards and comes with complimentary audit representation. In over two decades, we've never had a study trigger an audit or get overturned. We work with everyone from first-time investors with a single rental property to investment firms managing ten-figure portfolios. Our clients include CFOs building long-term tax strategies, property owners optimizing acquisitions, and CPAs looking to deliver more value to their clients.
