CREDIBILITY & WHY US

 The Gold Standard in Cost Segregation for Over 23 Years

Dollar Bag

Superior Benefits

Our studies typically reclassify an additional 6–15% of a property’s purchase price, excluding land, into shorter-life assets. On a $5 million building, that delivers $300k–$750k in accelerated depreciation that other providers miss.

Verified Account

Unsurpassed Methodology

Our team uses the most detailed and defensible IRS-recognized approaches 1 and 2 from the Cost Segregation Audit Technique Guide, to ensure every eligible component is accounted for to maximize your savings.

Punctuality

Precision Over Speed

Our 6–8 week process digs deep into every square foot of your building, identifying more assets for faster depreciation—and more money in your pocket than you would get from an automated study.

Shield

Unrivaled Audit Protection

With over 23 years of experience and more than 15,000 studies completed, our team has never lost an IRS audit. Audit defense is included at no extra cost—and unlike others, we do not cap our hours. That means total peace of mind for you.

WHAT IS COST SEG?

Why a Cost Segregation Study Is a Smart Move

Without a cost segregation study, most of your building is depreciated over 27.5 or 39 years—slow and inefficient.

A cost segregation study reclassifies eligible components (like electrical, plumbing, and finishes) into 5-, 7-, or 15-year categories—unlocking up to 100% bonus depreciation on those components in year one.

That typically means $300,000 to $700,000+ in immediate tax savings per property—money you can reinvest, not leave on the table.

Not Every Study is Created Equal

IRS-Recognized Approaches

The IRS outlines six approaches in its Cost Segregation Audit Technique Guide.
Only the top two are engineered to maximize write-offs and breeze through an audit.
Our team uses both—so you keep more, worry less, and sleep well.

CLIENT SUCCESS

Real Clients. Real Results.

Smart, hard-working folks across the U.S. are reclaiming tax dollars hiding in their properties. No loopholes—just smart strategy and honest savings. Hear their stories firsthand.

I have researched other cost segregation companies and find that they leave money on the table whereas the Cost Seg America team counts everything and usually finds 10-15% of the purchase price more. Jim Dougherty and the CSA team are very knowledgeable, responsive and on top of their game.

Discover how cost segregation can transform your tax strategy and put serious cash back in your pocket. Dive into our FAQs and see what you have been missing.

Can my CPA do a cost segregation study?

Not really. CPAs are not trained engineers—and cost segregation is an engineering-based analysis. Your CPA manages your overall tax strategy; our team provides the detailed building analysis. When your CPA and our team work together, you capture every allowable deduction with a rock-solid, audit-ready cost-segregation study—maximizing your savings.

How much does a cost segregation study cost?

Fees depend on the building type and engineering complexity; once basic property details are in hand, our team issues a fixed-fee quote—never a percentage of your refund. Straightforward structures cost less, while intricate or multi-use facilities require a higher investment. Each proposal includes an estimated first-year tax benefit so you can judge the ROI before committing.

Why choose Cost Seg America?

Our team delivers Detailed Engineering Studies that follow IRS Cost Segregation Audit Technique Guide Approaches #1 and #2, typically shifting an extra 6–15 % of the building’s purchase price—excluding land—into shorter-life asset classes, outperforming most providers. Expect larger, faster deductions, full audit defense at no extra cost, and a partner CPAs have trusted for 23 years.

When can you do a cost segregation study?

The ideal moment is the first tax year after purchase, but any property held for fewer than ten years can still “catch up” on missed depreciation with a single Form 3115 adjustment—no amended returns needed. Even buildings owned longer may qualify after major renovations or tenant improvements. Our team secures the full tax benefit whenever you start.

How does a cost segregation study work?

A cost segregation study breaks a commercial or residential rental building into its individual components—lighting, flooring, wiring, landscaping, and more—and moves those items from 27.5- or 39-year schedules into 5-, 7-, or 15-year classes. The result is front-loaded deductions that boost early cash flow and defer taxes. Our engineering team applies IRS Audit Technique Guide Approaches #1 and #2 to identify every eligible component, ensuring maximum depreciation, full audit protection, and increased cash flow.
