Cost Segregation Studies That Hold Up
Certified, IRS-compliant studies that accelerate depreciation and document the full asset picture.
What We Do
When you acquire, construct, or renovate a investment property, standard tax treatment depreciates the entire structure over a rigid 39-year schedule (or 27.5 years for residential rental). However, a substantial portion of your building consists of non-structural components.
A professional cost segregation study precisely identifies, reclassifies, and documents these eligible assets—accelerating your depreciation deductions and delivering substantial, front-loaded tax savings.
The Cost Segregation Initiatives Advantage
Our commitment to engineering precision and client-centricity defines our approach. A tax strategy is only as strong as its defense; every study we deliver is fully documented, legally supportable, and backed by recognized industry experts.
Whether you own a commercial or residential rental portfolio, we are dedicated to uncovering critical cash-flow advantages that optimize your bottom line.
Not all studies are the same
This is where most property owners, and even many CPAs, don't know what they're missing.
The majority of cost segregation firms focus almost exclusively on short-life assets: the components that accelerate depreciation the fastest and are the easiest to identify. It's efficient for the firm. But it leaves a significant gap in the analysis.
Every commercial building is made up of discrete systems: roofing, HVAC, plumbing, electrical, structural framing, flooring, specialty buildouts, and more. A complete study documents and assigns a defensible value to each of those systems, not just the ones that generate the largest short-life reclassifications.
Why does that matter?
Because buildings age, and components get replaced.
Example: If your roof needs to be replaced two years after acquisition and it hasn't been properly valued as a distinct asset, you lose the ability to write off the remaining 37 years of un-depreciated value at the time of disposal. That's a real, quantifiable loss, and it's entirely avoidable with a study that did the work correctly from the start.
The same principle applies to any major building system: HVAC equipment, plumbing infrastructure, electrical panels, elevators. When a component is replaced and its original cost basis hasn't been established, the tax benefit of that disposal disappears.
In many cases, recovering the depreciation on just one major component replacement is enough to offset the entire cost of the study.
For CPAs: Our full-system component analysis gives you the asset-level detail you need to properly account for partial asset dispositions under Reg. §1.168(i)-8. Most studies don't provide this. Ours do, and your clients will benefit from it for as long as they hold the property.
Cost segregation is only as strong as the documentation behind it.
