Cost segregation
Cost Segregation Services, Inc. (CSSI)
Cost Segregation Services, Inc. (CSSI) performs engineering-based cost segregation studies for owners of commercial and rental property, and sells two related specialty tax services beside them: 179D deductions for energy-efficient buildings and R&D tax credits for businesses improving products or processes.
The work is delivered through a nationwide network of tax professionals and is designed to sit alongside the client's own CPA rather than replace them. CSSI produces the study and the documentation supporting every number in it; the CPA or tax adviser files the return. A free online calculator gives an estimate of potential savings before anyone is engaged.
The company has been running studies since 2003 and reports more than 65,000 of them over 23 years, coverage in all 50 states, and a record of zero IRS audits triggered by its work. Its office is at 10211 Siegen Lane in Baton Rouge, Louisiana.
Fees, minimum property size and the terms of any audit support are not published, and the about, services and calculator pages sat behind a bot check during this crawl. Those terms should be confirmed directly before engaging.
Best for
Commercial and rental property owners who already have a CPA and want the study and its supporting documentation from a specialist, plus CPA firms that want to offer cost segregation, 179D and R&D work without hiring for it.
