Pay less tax on the real estate you already own.
Engineering-based cost segregation studies for residential and commercial property owners across the United States. IRS-compliant reports, fixed fees, and a real in-house team you can call — headquartered at 1643 24th St W Ste 102, Billings, MT 59102.
A cost segregation study accelerates the depreciation on your building.
When you buy, build, or improve real estate, the IRS makes you depreciate the building over 27.5 years (residential rental) or 39 years (commercial). That is glacial. A cost segregation study is an engineering-based analysis that reclassifies specific components — cabinetry, flooring, specialty electrical, land improvements, sitework — into 5-, 7-, and 15-year property.
The result: dramatically larger depreciation deductions in the early years of ownership, powerful bonus depreciation stacking, and real dollars back in your pocket at tax time. On a look-back study for a property you already own, missed depreciation catches up in a single year via Form 3115 — no amended returns required.
We produce reports for property owners in all 50 states. Every study is prepared by our team using engineering-based methodology aligned with the IRS Audit Techniques Guide.
