Cost Segregation Services

What Cost Segregation Services does

CSSI Cost Segregation Services is a privately held professional services firm founded in 2003 and headquartered in Baton Rouge, Louisiana. The company specializes in engineering-based cost segregation studies that accelerate depreciation schedules on commercial real estate to reduce federal income tax liability and increase cash flow for property owners. Over its operating history, CSSI reports having completed more than 65,000 studies and generating over $10 billion in client tax savings, while maintaining a record of zero IRS audits triggered across that work. The firm operates a nationwide network of tax professionals covering all 50 states and reports a headcount in the 101-250 range.

The company's product portfolio extends beyond core cost segregation into two adjacent specialized tax services: Section 179D Tax Deduction Services, which enables property owners to claim up to $5.81 per square foot for energy-efficient building improvements in lighting, HVAC, and building envelope, and R&D Tax Credit Services, which helps manufacturing, technology, and engineering firms claim dollar-for-dollar federal and state credits for qualifying research activities. CSSI supports customer acquisition through a sales-led go-to-market motion that combines direct outreach, free online calculators (cost segregation, R&D, 179D), an R&D State Tax Credit Map resource, educational blog content, and formal partnerships with CPAs and tax professionals who refer clients in exchange for specialized technical expertise.

CSSI monetizes via quote-based professional services fees determined after a no-cost property analysis, with a stated 48-hour turnaround on initial estimates and 2-week report delivery. Target customer segments are horizontal and distributed across three personas: CPAs and tax professionals seeking outsourced specialty tax expertise, commercial real estate investors (multifamily, retail, industrial, office), and innovative businesses engaged in qualifying R&D activities. No external funding, M&A activity, patents, awards, or AI/ML capabilities are disclosed in the available data.
