Comparing Cost Segregation Companies

What to Look for in a Cost Segregation Company

When comparing cost segregation companies, look beyond projected tax savings. The methodology, engineering expertise, property analysis, and documentation behind a study determine how its conclusions are developed and supported. These are four important factors to consider when evaluating a cost segregation firm.

Engineering expertise used in a cost segregation study
01

Engineering Expertise

Look for a provider that evaluates the physical property and applies engineering and tax principles to identify and classify qualifying building components.

On-site property verification for a cost segregation study
02

Site Verification

Property-specific analysis helps document the actual building and its components rather than relying solely on generalized assumptions or allocation percentages.

Detailed documentation for an IRS-aligned cost segregation study
03

IRS-Aligned Documentation

A quality study should clearly document asset identification, classifications, valuation methodology, and the support behind the resulting depreciation schedules.

Audit support and defensibility for a cost segregation study
04

Audit Support

Ask what happens after the study is delivered, including what documentation is retained and what support is available if the study is later examined.

CSA Partners takes an engineering-based approach to cost segregation with property-specific analysis, detailed documentation, site verification, and ongoing audit support.

BUILT IN THE FIELD

Cost Segregation Expertise That Goes Beyond the Spreadsheet

Every CSA Partners study begins with real-world observation — not assumptions. From there, our proprietary SiteWize™ process captures detailed construction data, measurements, and photographic documentation that strengthen every conclusion we deliver.

In addition, our engineers evaluate property components using construction-level detail to support asset classifications and depreciation treatment. The result is an engineering-based cost segregation study built not only to identify accelerated depreciation, but also to provide the documentation needed if those positions are later reviewed.

Real-time data capture

Measurements and component conditions recorded on the spot.

Photographic documentation

Visual proof for every position, stored for the life of the study.

Construction-grade detail

Every classification traces back to physical evidence.

OUR SERVICES

Today’s tax environment requires more than aggressive numbers.

As a result, real estate owners and their advisors need tax strategies supported by rigorous analysis and defensible documentation. As a nationwide cost segregation company and real estate tax strategy partner, CSA Partners combines engineering, tax expertise, and property-specific analysis to identify opportunities while preparing for the scrutiny those positions may face.

Higher documentation expectations demand engineering-based cost segregation studies that identify accelerated depreciation while providing the support needed to withstand review.

Likewise, future tax consequences deserve thoughtful planning — not last-minute reactions.

Similarly, substantial land investments deserve documentation that protects them for the long term.

Finding the deductions is easy. Keeping the savings is the hard work. That’s why we built our firm around the hard work.

We’re confident enough in every study we produce to stand behind our work. If a CSA Partners study is audited and a significant depreciation we identified is ultimately disallowed, we’ll refund our engagement fee.

After all, confidence shouldn’t stop when the report is delivered.
