Questions

Frequently asked questions

It reclassifies parts of your building (fixtures, finishes, systems, site work) from slow 27.5/39-year depreciation into faster 5-, 7-, and 15-year lives — so you deduct far more, far sooner.

It varies case by case, but many owners accelerate roughly 20–28% of their depreciable basis into the early years. On a $1M building that can mean six figures of Year-1 deductions with 100% bonus depreciation. Your study is property-specific.

A properly documented study doesn't raise audit risk — it's a long-established, IRS-recognized strategy. Every Cosegra study follows the IRS Audit Techniques Guide and is reviewed by a licensed CPA and structural engineer.

100% bonus depreciation is restored for property placed in service after Jan 19, 2025 — meaning the entire reclassified amount can be deducted in Year 1. That makes a study more valuable now than it's been in years.

No. A look-back study lets you claim missed depreciation without amending prior returns, via a Form 3115 catch-up. We offer that as an add-on.

No — we hand your CPA a clean, audit-defensible report they plug straight into your return. Many accounting firms actually white-label Cosegra to offer this to their own clients.
