Cost Segregation Percentages by Property Type

Compare 5-year, 15-year, and total accelerated allocation bands across 45 property types. Every percentage uses depreciable basis after land is removed.

This published release is generated from the saved workbook, not copied from page text. Matthew Gigantelli reports completing or reviewing approximately 8,000 studies over five years. Those confidential studies inform his expertise, but they are not rows in this 45-band public dataset and do not establish property-type sample counts or percentiles.
