  • Nonresident situs. Limit Hawaii-situs assets for nonresidents; avoid business situs for intangibles.
  • Valuation & deductions. Use strong local appraisals; keep court orders/invoices to support deductions.
  • Liquidity & §6166. Coordinate cash for the 9-month payment; if federal §6166 applies, expect proportional coordination for HI-situs business interests.
