Hawaii Estate Tax & Probate — Complete Guide
What executors and families need to know about Hawaii probate and the Hawaii estate tax (HRS ch. 236E): who files, what’s taxed, nonresident situs, Form M-6, deadlines & extensions, elections (marital/QTIP, charitable), valuation, and planning—plus a calculator, case notes, and a nonresident guide.
Hawaii Probate Basics
Courts & intestacy
Probate is handled by the Hawaii state courts. If there is no will, distribution follows Hawaii’s intestacy statutes. Ancillary probate is common where nonresidents own Hawaii real property.
Typical probate steps
Open estate → appoint personal representative → notices → inventory & appraisals → pay debts/expenses/taxes → accountings → distribution & close.

Planning Ideas to Reduce Hawaii Estate Tax
- Marital & charitable planning. Align federal elections (QTIP/charitable) with Hawaii filing to defer or reduce tax.
- 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.
