New to estate planning? You’re in the right place. A living trust is a legal document that holds your family’s assets so they pass directly to your loved ones — no probate court, no delays, no public record. That’s the core idea.
If you’re just starting to figure this out, I’d suggest reading Having the Estate Planning Talk with Your Parents first — it walks through the whole picture and how to get the conversation started. Then come back here for the Hawaii-specific rules.
Already know the basics? Keep scrolling — everything below is specific to Hawaii.
You’re not alone in this. As someone who went through the estate planning process with my own aging parents, I know the weight of these conversations — the awkwardness, the guilt, the fear that you’re not doing enough or doing it too late. Take a breath. You’ve found the right place, and Hawaii has some rules that make estate planning both more urgent and more nuanced than in most states.
Here’s the headline: Hawaii has the second-highest estate tax rate in the nation — 20% on the largest estates, trailing only Washington State. The exemption is a relatively generous $5.49 million per person, but in a state where a single-family home on Oahu can easily exceed $1 million, that threshold isn’t as far away as it sounds.
But here’s the good news — and it’s genuinely rare: Hawaii is one of the only states that allows estate tax portability between spouses. If the first spouse doesn’t use their full exemption, the surviving spouse can claim the unused portion. That means a married couple can potentially shelter up to $10.98 million from Hawaii estate tax without any special trust planning — something that’s not possible in most estate tax states.
Hawaii also has a legal relationship found nowhere else in the country: the reciprocal beneficiary, a status that provides inheritance rights and other protections to qualifying individuals who cannot legally marry each other.
Here’s everything you need to know about estate planning in Hawaii — no legal jargon, just clear answers from a son who’s been through it.
Hawaii Estate Tax: The Second-Highest Rate in America — But With Portability
Hawaii estate tax exemption: $5,490,000 per person (2026). Hawaii’s estate tax is imposed under HRS Chapter 236E, with graduated rates from 10% to 20%. The 20% top rate applies to taxable estates exceeding approximately $5 million above the exemption. Hawaii is one of only about a dozen states (plus DC) with its own estate tax, and its top rate is second only to Washington State’s.
How it works: Hawaii computes the estate tax using its own graduated rate schedule. The exemption amount is set by reference to the applicable exclusion amount for Hawaii estate tax purposes. Unlike some states that use the old federal state death tax credit method, Hawaii has its own rate table.
What Hawaii Estate Tax Actually Costs Your Family
| Total Estate Value | Approximate HI Estate Tax | Effective Rate (on total estate) |
|---|---|---|
| $5,490,000 | $0 | 0% (at the exemption) |
| $6,000,000 | ~$51,000 | ~0.9% |
| $7,000,000 | ~$179,000 | ~2.6% |
| $8,000,000 | ~$339,000 | ~4.2% |
| $10,000,000 | ~$699,000 | ~7.0% |
| $15,000,000 | ~$1,599,000 | ~10.7% |
How families cross the $5.49 million line in Hawaii: Consider a couple on Oahu. Their home is worth $1.3 million, they own a neighbor island vacation condo worth $600,000, they have $1.5 million in retirement accounts, $500,000 in investments, $400,000 in life insurance, and $200,000 in other assets. That’s $4.5 million — and it all belongs to the surviving spouse after the first death. Add a few years of appreciation on that Oahu home and retirement growth, and they’re at or above $5.49 million.
Portability: Hawaii’s Rare Advantage for Married Couples
Hawaii allows estate tax portability. This is rare — most estate tax states (including Oregon, Massachusetts, Illinois, Washington, and New York) do not offer portability. In Hawaii, the surviving spouse can claim the deceased spouse’s unused exclusion amount, potentially sheltering up to $10.98 million combined from Hawaii estate tax.
How portability works in Hawaii:
- When the first spouse dies, a Hawaii estate tax return (Form M-6) must be filed to elect portability — even if no tax is owed
- The deceased spouse’s unused exclusion amount (DSUEA) transfers to the surviving spouse
- The surviving spouse can add the DSUEA to their own exemption
- This election is made on the Form M-6 filed for the first spouse’s estate
What portability means in practice: If the first spouse dies with a $3 million estate, their unused exclusion is roughly $2.49 million ($5.49M minus $3M). The surviving spouse can add that $2.49 million to their own $5.49 million exemption — for a total of approximately $7.98 million sheltered from Hawaii estate tax at their death.
Does portability eliminate the need for trust planning? Not entirely. Portability protects against the estate tax, but it does not:
- Avoid probate — you still need a trust or other probate avoidance tool for that
- Protect against creditors of the surviving spouse
- Shield appreciation — assets that grow in value after the first death are taxed in the surviving spouse’s estate, with no shelter from the first spouse’s exemption
- Provide incapacity protection
For families with estates well above $10.98 million — or families who want both tax protection and probate avoidance — a credit shelter trust still makes sense even with portability available.
Two Trust Types in Hawaii
Hawaii adopted the Hawaii Uniform Trust Code at HRS Chapter 554D, effective January 1, 2022. Under the UTC, a trust is presumed revocable unless the terms expressly state it is irrevocable.
Revocable Living Trust
- Avoids probate — the primary benefit for Hawaii families given supervised probate as the default
- You maintain full control — revocable and amendable during your lifetime
- Provides privacy — trust assets stay out of public court records
- Provides incapacity protection — successor trustee steps in without court involvement
- Avoids ancillary probate — critical if you own property on the mainland or on multiple islands
- Does NOT reduce Hawaii estate tax — trust assets are part of your taxable estate
- Hawaii has TOD deeds (since 2011), but a trust covers all asset types and provides incapacity protection
Irrevocable Trust
- Once established, you give up control — the trade-off for tax and protection benefits
- Can reduce estate tax — assets transferred irrevocably are removed from the taxable estate
- Credit shelter trust — can lock in the first spouse’s exemption and shield future appreciation (even with portability, a CST may be superior for large estates)
- ILIT — keeps life insurance proceeds outside the estate entirely
- Medicaid protection — can protect assets from Med-QUEST recovery if established 5+ years before applying
- Hawaii allows DAPTs but with the most restrictive rules in the nation (25% net worth cap, limited asset types — HRS Chapter 554G)
- Maximum trust duration: ~90 years under the Uniform Statutory Rule Against Perpetuities (HRS Chapter 525)
Hawaii Rules at a Glance
Probate Rules
- Court system: Circuit Court (4 circuits: First/Oahu, Second/Maui, Third/Big Island, Fifth/Kauai)
- Administration: Supervised (default) or informal under HRS 560 (UPC)
- Small estate affidavit: Personal property ≤$100,000 (HRS 560:3-1201)
- Creditor claims period: 4 months from first publication; 60 days from notice to known creditors
- Typical timeline: 6-12 months; complex estates may take longer
- Attorney fees: No statutory schedule — reasonable compensation; typically 3-7% of estate value
Tax Rules & Property
- Estate tax: $5.49M exemption, graduated rates 10%-20%
- Portability: Yes — rare among state estate taxes
- No inheritance tax
- No gift tax
- Filing: Form M-6 with HI Dept of Taxation, due 9 months after death
- Common law (separate property) state
- TOD deeds: Available (HRS Chapter 527, since 2011)
- Tenancy by the entirety: Available for married couples and reciprocal beneficiaries
- Homestead exemption: $30,000 (head of family/65+) or $20,000 (all others) — HRS 651-92
Reciprocal Beneficiary Relationships: A Legal Status Found Only in Hawaii
Hawaii has a legal relationship that exists nowhere else in the country: the reciprocal beneficiary (HRS Chapter 572C). Originally enacted in 1997 as an alternative to marriage for same-sex couples, this status now primarily serves close family members who cannot legally marry each other — such as siblings living together, or an adult child caring for an elderly parent.
Who Qualifies
Two people who are legally prohibited from marrying each other under Hawaii law (typically blood relatives). Both must be at least 18, not currently married or in another reciprocal beneficiary relationship, and consent freely. Registration is through the Hawaii Department of Health.
Estate Planning Rights Provided
- Intestate inheritance — right to inherit from each other without a will
- Tenancy by the entirety — can hold property with full creditor protection and survivorship rights (since 2012)
- Healthcare decision-making — hospital visitation and medical decisions
- Wrongful death — right to sue
- State employee benefits — insurance, pension, workers’ compensation
Why this matters for estate planning: If your parents have a reciprocal beneficiary registration — even one from years ago — it may affect their intestacy rights, property ownership options, and healthcare decision authority. An estate planning attorney should ask about this status and account for it in any plan.
Hawaii’s Homestead Exemption: Minimal Protection in a High-Cost State
Hawaii’s homestead exemption (HRS 651-92) provides creditor protection of only $30,000 for heads of family or those over 65, and $20,000 for everyone else. In a state where the median single-family home on Oahu exceeds $1.1 million, this provides virtually no meaningful protection.
Compare this to Florida’s unlimited homestead, Texas’s unlimited homestead, or even Massachusetts’s $1,000,000 declared homestead. Hawaii’s exemption is among the lowest in the nation relative to home values.
What this means: Hawaii families cannot rely on the homestead exemption for asset protection the way families in other states can. Trusts, tenancy by the entirety, and proper insurance planning take on greater importance here.

What Estate Planning Costs in Hawaii
| What You’re Paying For | Typical Range in Hawaii | When You’d Use It |
|---|---|---|
| Simple will | $450 – $1,150 | Single person, straightforward assets |
| Revocable living trust (individual) | $1,500 – $3,950 | Individual wanting to avoid probate and plan for incapacity |
| Full estate plan (married couple) | $2,200 – $5,650 | Married couple — trust, wills, POA, advance directive, deeds |
| Full estate plan package (trust + will + POA + advance directive) | $1,500 – $5,650 | Most families — this is what you actually need |
| Trust administration after death | $2,000 – $6,000+ | Settling a trust estate after a parent’s death |
The math on portability elections: Filing a Form M-6 to elect portability when the first spouse dies can shelter up to an additional $5.49 million from Hawaii estate tax at the second death. Even if the first spouse’s estate is well below the exemption and no tax is owed, the cost of filing the return (typically $1,000-$3,000 through an attorney or CPA) is a small price to preserve millions in exemption.

With a Trust vs. Without (Probate) in Hawaii
| Factor | With a Living Trust | Without (Probate) | Why It Matters |
|---|---|---|---|
| Timeline | Weeks to a few months | 6-12 months typical; complex estates longer | Your family waits months for assets to transfer |
| Cost | $1,500-$5,650 (one-time trust creation) | 3-7% of estate value in attorney/court costs | On a $1M estate, probate can cost $30,000-$70,000 |
| Privacy | Completely private | Public record — filed with Circuit Court | Anyone can see what your parents owned and who receives it |
| Court involvement | None | Required — Hawaii defaults to supervised administration | Supervised probate means more court oversight than most states |
| Real estate | Property in trust passes immediately | Goes through probate (TOD deed available as alternative) | TOD deeds work for simple situations; trust is more flexible |
| Multi-island / mainland property | No ancillary probate needed | Separate probate in each state where property is located | Hawaii families with mainland property face ancillary probate without a trust |
| Incapacity protection | Successor trustee steps in seamlessly | Court-supervised guardianship needed | Guardianship is public, expensive, and emotionally difficult |
| Estate tax | Still applies — same rates | Still applies — same rates | A revocable trust does NOT reduce Hawaii estate tax |
| Med-QUEST recovery | Generally protected (trust assets pass outside probate estate) | Exposed (probate assets subject to recovery) | Hawaii follows probate-only estate recovery — a meaningful advantage for trusts |

Common Estate Planning Mistakes in Hawaii
Hawaii has its own estate tax with an exemption of just $5.49 million — well below the federal $13.61 million threshold. Families with estates above that amount may owe state estate tax even if they owe nothing federally.
A trust only avoids probate for assets that have been retitled into it. An unfunded trust is just an expensive stack of paper. Real estate, bank accounts, and investments all need to be moved into the trust’s name.
A will does not avoid probate — it goes through it. A will tells the probate court what you want, but the court still controls the process. Only a trust, joint ownership, beneficiary designations, and certain deeds bypass probate entirely.
Retirement accounts (401k, IRA) and life insurance pass by beneficiary designation — not by your will or trust. Outdated designations (like a former spouse) override everything else in your estate plan.
A trust handles what happens after death, but a durable power of attorney and healthcare directive handle what happens if you become incapacitated. Without these, your family may need an expensive court-supervised guardianship.
The best way to avoid these mistakes? Work with an estate planning attorney who knows Hawaii law. A qualified attorney will catch the state-specific issues that generic online advice misses.
Other Important Planning Tools in Hawaii
Advance Health-Care Directive (HRS Chapter 327E)
Hawaii uses a single combined document called an Advance Health-Care Directive under the Uniform Health-Care Decisions Act. It has two parts: Part 1 names a healthcare agent (power of attorney for healthcare), and Part 2 states your treatment preferences (living will instructions).
Execution requirements: The directive must be in writing, dated, and signed by the principal. It must be witnessed by either two witnesses (at least one of whom is not related and not an heir) OR acknowledged before a notary public.
Hawaii has an active POLST (Provider Orders for Life-Sustaining Treatment) program. A POLST is a medical order — different from an advance directive — signed by both the patient and a healthcare provider, covering CPR, level of treatment, and artificial nutrition. It’s immediately actionable by emergency personnel.

Durable Power of Attorney (HRS Chapter 551E)
Hawaii adopted the Uniform Power of Attorney Act. Powers of attorney are durable by default — they survive the principal’s incapacity unless the document says otherwise. Must be signed and acknowledged before a notary public. Springing POAs are allowed — the principal can specify that the POA takes effect only upon incapacity, with a physician or psychologist making the determination.

Military Families: Special Considerations
Hawaii has one of the largest military populations in the country — Joint Base Pearl Harbor-Hickam, Schofield Barracks, Marine Corps Base Hawaii, and others. Key estate planning considerations:
- Domicile matters: Under the Servicemembers Civil Relief Act (SCRA), military members retain their home-of-record state for tax purposes regardless of where they’re stationed. A service member domiciled in Texas or Florida avoids Hawaii estate tax on their worldwide assets.
- Multi-state property: Military families frequently own homes in multiple states. A revocable living trust avoids ancillary probate in each state.
- MSRRA: The Military Spouses Residency Relief Act allows spouses to maintain their own domicile state or claim the servicemember’s domicile.
- Beneficiary designations: SGLI, TSP, and military retirement benefits all pass by beneficiary designation — keeping these current is critical, especially after PCS moves, marriages, or divorces.
Native Hawaiian Homelands
If your family holds a homestead lease from the Department of Hawaiian Home Lands (DHHL), standard estate planning tools may not work as expected. DHHL leases are available only to individuals who are at least 50% Native Hawaiian, and heirs must be at least 25% Native Hawaiian. These lands cannot be freely transferred — they must remain within the Native Hawaiian community. Specialized legal advice is essential for families with DHHL leases.
Long-Term Care Considerations
Hawaii’s Medicaid program (Med-QUEST) covers long-term nursing home care, but eligibility requires meeting strict asset limits ($2,000 for an individual). The look-back period is 5 years (60 months). Hawaii follows probate-only estate recovery — meaning assets in trusts, joint accounts, and beneficiary-designated accounts are generally not subject to recovery after the Medicaid recipient’s death. This makes both revocable and irrevocable trusts particularly valuable for Medicaid planning in Hawaii.

Questions to Ask Before You Hire a Hawaii Estate Planning Attorney
- How many estate plans do you create per year, and what percentage of your practice is trust and estate work?
- My parents’ estate is approximately $[X] — can you walk me through their Hawaii estate tax exposure and whether portability election alone is sufficient?
- Should we rely on portability or set up a credit shelter trust — what’s the right approach for our family’s size of estate?
- What’s included in your flat fee (trust, pour-over will, POA, advance health-care directive, deed transfers)?
- Will you help with funding the trust — retitling real estate deeds, bank accounts, and investments?
- My parents own property on the mainland / on multiple islands — how do you handle multi-state or multi-island planning?

Recent Hawaii Updates
- January 2022 — Hawaii Uniform Trust Code (HRS 554D): Hawaii adopted the UTC, replacing the older Uniform Trustees’ Powers Act. Major modernization of trust law covering creation, modification, duties, and liability. Trusts are now presumed revocable unless stated otherwise.
- Estate Tax Exemption — $5.49M (2026): The Hawaii estate tax exemption remains at $5,490,000. A bill to raise the exemption (SB 721) was introduced in the 2025 legislative session but did not advance.
- TOD Deeds — Exempt from Conveyance Tax: Transfer-on-death deeds under HRS Chapter 527 continue to be exempt from Hawaii’s graduated conveyance tax, making them a cost-effective probate avoidance tool for residential property.
- Federal — One Big Beautiful Bill Act (July 2025): The federal estate tax exemption is now permanently set at $15 million per individual. Hawaii’s $5.49 million exemption means families in the $5.49M-$15M range owe Hawaii estate tax but zero federal estate tax — making state-level planning the only tax planning that matters for these families.
- Medicaid (Med-QUEST): Hawaii continues to follow probate-only estate recovery under HRS 346-37. Assets that pass outside probate (trusts, joint accounts, beneficiary designations) are generally protected from recovery.
