Matthew Gigantelli's Hawaii Analysis

ASCSP Member M009-25 · Lead Cost Segregation Engineer

"Hawaii is one of the most compelling states for cost segregation despite its non-conformity with bonus depreciation. The reason is simple: property values are among the highest in the nation, and the tourism-driven hospitality market produces exceptional reclassification rates. Hotels and resort properties in Hawaii are loaded with FF&E, specialty finishes, and landscaping that qualify for accelerated depreciation. With a top state rate of 11% — the second highest in the country — even standard accelerated depreciation (without bonus) delivers substantial Hawaii tax savings."

Bonus Depreciation Status

Hawaii uses static IRC conformity and has historically decoupled from federal bonus depreciation under §168(k). Cost segregation accelerates federal depreciation, but Hawaii follows standard MACRS schedules at the state level. The high state tax rate (up to 11%) makes careful planning essential.

100% Bonus Depreciation Restored (July 2025): The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for qualifying assets placed in service after 2022. This dramatically increases cost segregation ROI in Hawaii.

Hawaii-Specific Considerations

  • Non-conforming — decoupled from §168(k) bonus depreciation at state level
  • Second-highest top state income tax rate (11%) makes standard accelerated depreciation very valuable
  • Lowest property tax rate in the nation at 0.27% (Tax Foundation, 2026)
  • Tourism/hospitality properties have among the highest reclassification rates nationally (32-42%)
  • High land-to-building ratios in coastal areas reduce depreciable basis — careful allocation critical
  • Vacation rental regulations vary by county and affect material participation analysis

How Cost Segregation Works in Hawaii

Cost segregation is an IRS-approved tax strategy that reclassifies components of your Hawaii 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 Hawaii property owners, this means turning a $5.8M commercial property into $72,000 - $200,000 of first-year tax savings instead of waiting decades for the same deduction.
