Amir Seyedhashemi is the founder of Cost Seg Labs. With a background in architecture, construction documentation, and project management, he brings a technical understanding of how buildings are assembled, documented, and carried through the construction process. That perspective informs a methodical, building-based approach to cost segregation.
Amir Seyedhashemi brings an architectural design perspective to the study process, with a focus on building components, construction detail, and technical classification analysis. His role helps strengthen the accuracy and support behind each study, especially for properties where layout, finishes, systems, and use matter to the final result.
Our approach combines architectural building analysis with tax implementation awareness, allowing us to deliver studies that are both technically grounded and practical to use at filing time. We coordinate directly with CPAs and EAs to make implementation clean and efficient.
Our studies are prepared with documentation, methodology, and tax implementation in mind. If questions arise, we work with clients and their tax professionals to support the study and explain the basis for our conclusions.
A cost segregation study is an IRS-approved engineering analysis that reclassifies building components from 39-year depreciation (for commercial property) or 27.5-year (for residential rental) into shorter 5, 7, or 15-year asset classes. This accelerates your depreciation deductions, significantly reducing your taxable income and increasing your cash flow.
Property owners who have purchased, constructed, or renovated commercial real estate — including office buildings, retail centers, warehouses, hotels, multi-family properties, and medical facilities — typically qualify. Properties with a depreciable basis of $500,000 or more tend to generate the most significant tax benefits.
Savings vary based on property type, cost basis, and your tax rate, but our clients typically see $50,000 to $500,000 in additional depreciation in the first year alone. Our team will provide a free benefit analysis to estimate your specific savings before you commit to a full study.
When performed by qualified engineers following IRS Revenue Procedure 87-56, cost segregation is entirely legitimate and IRS-compliant. At Cost Segregation Laboratories, every study is conducted using an engineering-based methodology with thorough documentation, creating an audit-ready report that withstands scrutiny.
We typically need the property purchase price or construction cost, the closing statement or cost basis documentation, depreciation schedule (if one exists), and basic property details. Floor plans and construction records are helpful but not always required. We will guide you through the process.
We coordinate directly with your CPA or EA to ensure the report is structured for clean implementation at filing time. Our goal is to make the handoff straightforward — not create extra work for your tax professional.
Yes. You can perform a lookback study on properties purchased in prior years and catch up on missed depreciation in the current tax year — without amending prior returns. This is allowed under IRS Revenue Procedure 2002-9 and can produce significant results.
We stand behind our studies and work with clients and their tax professionals if questions arise. Our documentation is designed to support the classification decisions made in the study. We assist with explanations of methodology and findings if IRS review occurs.
