Highly recommendedIf it's ever questioned, the deduction survives on documentation — the engineering methodology, the asset-by-asset breakdown, the source records, and a clear written answer to the examiner's letter. Without that, the reclassification can be disallowed even when it was correct.

Where the accelerated deductions come from
Commercial buildings are depreciated over 39 years by default. That's a slow drip. A properly-scoped cost segregation study typically reclassifies 15–40% of the depreciable basis into 5-, 7-, and 15-year categories — hospitality and specialty-use properties skew toward the top of that range.
Short-life property in a commercial context includes decorative finishes, dedicated process electrical, specialty plumbing, decorative millwork, movable partitions, kitchen equipment build-outs, medical/dental infrastructure, security and specialty low-voltage systems, and much more. Land improvements — parking lots, sitework, fencing, exterior lighting, landscaping — sit at 15 years.
For a look-back study on a property placed in service in a prior year, we prepare the Form 3115 supporting documentation. Missed depreciation flows through as a single current-year catch-up — no amended returns.
What we need from you
Closing statement or AIA / construction docs
Purchase settlement statement, or AIA G702/G703 and pay-app history for new construction.

Architectural, structural, MEP drawings if available. Not required — we can work with photos.
Rent roll (multifamily) or lease abstracts
Helpful for classifying tenant-specific improvements.
Placed-in-service date + prior depreciation schedule
For look-back studies, we need the last CPA-prepared depreciation schedule.
