Matthew Gigantelli's Arizona Analysis
ASCSP Member M009-25 · Lead Cost Segregation Engineer
"Arizona's rapid growth and full federal conformity make it a standout for cost segregation. Phoenix is one of the fastest-growing metros in the country, with massive multi-family and industrial development. Newer construction means more qualifying personal property components. The 2.5% flat state rate is modest but adds up, especially on high-value Scottsdale resort and hospitality properties."

How Cost Segregation Works in Arizona
Cost segregation is an IRS-approved tax strategy that reclassifies components of your Arizona property from the standard 39-year (commercial) or 27.5-year (residential) depreciation schedule to shorter 5, 7, and 15-year recovery periods. With 100% bonus depreciation restored under the One Big Beautiful Bill Act, these reclassified components can be fully depreciated in year one.
For Arizona property owners, this means turning a $2.6M commercial property into $40,000 - $105,000 of first-year tax savings instead of waiting decades for the same deduction.
