In one sentence: a cost segregation study is an engineer taking your building apart on paper, sorting its pieces by how fast the tax code lets you write them off, and documenting every piece so the deduction holds.
Meet Grace. She owns a dental office building she bought for $900,000. To the IRS, a commercial building is one asset written off over 39 years, about $23,000 a year. To an engineer, it is hundreds of assets. The parking lot and landscaping are 15-year property. The cabinetry, specialty plumbing for the chairs, and dedicated electrical for the equipment are 5-year property. The carpet is 5-year property. Our engineer measured each one, priced it from real cost records, and documented it. The study moved roughly $290,000 of Grace's building into those short-life categories, and under current law those categories can be deducted in full in year one. Her first-year deduction went from $23,000 to about $290,000. Her CPA filed it. Her tax bill dropped by roughly $100,000.
That is the whole product. Engineering instead of guessing. The IRS publishes a guide describing six ways to do this work; we use only the two most rigorous, and every study is built to be read by the examiner who may one day open it.

Cost Segregation Accelerates Your Depreciation - Legally.
A cost segregation study reclassifies components of your building from long-life real property (depreciated over 27.5 or 39 years) into shorter-life categories (5, 7, or 15 years). This dramatically accelerates your depreciation deductions, reducing your current-year tax liability and generating immediate cash flow.
With 100% bonus depreciation reinstated after January 19th 2025, every qualifying component identified in your study can be fully deducted in Year 1. On a $2M commercial property, that can mean $400,000+ in Year 1 deductions alone.
