The Gold Standard in Cost Segregation for Over 23 Years
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.
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.
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.
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 Sets Us Apart?
Our team uses the top two approaches approved by the IRS Cost Segregation Audit Technique Guide: 1. Detailed Engineering Approach from Actual Cost Records and 2. Detailed Engineering Cost Estimate Approach. These are the gold standards—thorough, accurate, and defensible.
Unfortunately, many providers still rely on modeling software and generic estimates, undervaluing critical building components and leaving substantial tax savings unclaimed. Those shortcut studies seldom withstand IRS scrutiny—a risk our team will never ask you to take.
