Does Hawaii Have an Inheritance Tax? What Heirs Need to Know

If you just inherited money, property, or assets from someone who died in Hawaii, the first question on your mind is probably whether you owe tax on what you received. The short answer: Hawaii has no inheritance tax. Nothing you receive as a beneficiary is taxed at the state level based on the fact that you inherited it.

That said, Hawaii does have an estate tax — and the two are easily confused. Understanding which is which, and which one applies to your situation, can save you a lot of anxiety and prevent a costly filing mistake.

Inheritance Tax vs. Estate Tax: The Key Difference

An inheritance tax is levied on the beneficiary — the person who receives assets from an estate. The tax is based on the relationship between the heir and the deceased, and the heir pays it out of their own pocket. About six states (Iowa, Kentucky, Maryland, Nebraska, New Jersey, Pennsylvania) still impose an inheritance tax. Hawaii is not one of them.

An estate tax is entirely different. It is levied on the estate itself — the total pool of assets owned by the deceased person at the time of death. The tax is paid by the estate (typically by the executor, using estate funds) before anything is distributed to heirs. The beneficiaries receive what remains after the estate settles its debts and taxes.

Hawaii imposes an estate tax, not an inheritance tax. If you are an heir or beneficiary, you are not personally responsible for paying any Hawaii state tax on your inheritance. The executor handles that — if the estate even owes anything at all.

Hawaii's Estate Tax: Who Actually Pays It

Hawaii's estate tax only applies if the total gross value of the estate exceeds $5,490,000. The Hawaii legislature froze the exemption at this amount, and it has not changed. For most families, the estate will fall well below this threshold, meaning the estate owes zero Hawaii estate tax and heirs receive their inheritance without any state estate tax being taken out.

For estates above $5,490,000, Hawaii imposes a graduated tax starting at 10% on the first million over the exemption, climbing through 11%, 12%, 14%, and 15.7%, and reaching a top rate of 20% on amounts more than $10 million over the exemption. Hawaii's 20% top rate is the highest state estate tax rate in the country.

Here is where it gets counterintuitive: the federal estate tax exemption is approximately $15 million for deaths in 2026. That means an estate worth, say, $8 million owes zero federal estate tax but still owes a significant Hawaii state estate tax — because the state exemption is more than $9 million lower than the federal one. Many families are blindsided by this gap.

What Heirs Actually Face in Hawaii

Even though there is no inheritance tax, beneficiaries inheriting property or investment accounts in Hawaii may face other tax obligations:

Capital gains on inherited assets. If you inherit a Hawaii property and later sell it, you may owe capital gains tax on the appreciation that occurred after you inherited it. Fortunately, the federal step-up in basis rule (IRC § 1014) resets your cost basis to the fair market value of the asset on the date of death. If you sell shortly after inheriting, there is often little or no taxable gain. If you hold the asset for years and it appreciates further, you owe capital gains tax only on the post-inheritance appreciation.

HARPTA withholding if you sell real property. If you inherit Hawaii real estate and sell it as a nonresident, Hawaii will withhold 7.25% of the gross sale price at closing under the Hawaii Real Property Tax Act (HARPTA). This is not a final tax — it is a prepayment mechanism. If your actual gain is lower than the withholding implies (especially with a stepped-up basis), you file Form N-288C to recover the over-withheld amount. But it creates a cash-flow disruption that mainland beneficiaries frequently do not anticipate.

Federal income taxes on estate income. If the estate generates income while it is being administered — rent from an inherited property, dividends from a brokerage account — that income is taxable. The executor reports it on Form N-40 (Hawaii Fiduciary Income Tax Return) and issues Schedule K-1 forms to beneficiaries so each heir can report their share on their personal return.

The Portability Consideration for Surviving Spouses

If you are a surviving spouse, there is an important estate planning nuance worth understanding. Hawaii allows portability of the estate tax exemption between married couples — meaning the executor can transfer the deceased spouse's unused exemption to you, doubling your future exemption to up to $10,980,000.

To claim this, the executor must file Form M-6 (Hawaii Estate Tax Return) within nine months of death, even if the estate owes no tax. This filing is purely to make the portability election. Missing this deadline permanently forfeits the unused exemption — a potentially costly mistake for couples with combined estates between $5.49 million and $10.98 million.

What Beneficiaries Should Actually Do

If you are an heir or beneficiary and the estate is below $5,490,000, your main concern is:

1. Ensure the executor files Form M-6A (Request for Release) to clear any state tax lien on inherited real property. Title insurance companies will not underwrite a future sale without this release, even if zero estate tax is owed.
2. If you inherit Hawaii property and plan to sell it, get a date-of-death appraisal immediately. This establishes your stepped-up basis and is the key document for recovering HARPTA withholding via Form N-288C.
3. If you receive a Schedule K-1 from the estate, report that income on your personal return.

If you are the executor navigating this on behalf of the estate — particularly managing the estate tax filing, HARPTA withholding, or the Form M-6A release — the Hawaii Final Tax & Estate Tax Guide walks through each step in plain English, with the exact forms, deadlines, and sequences you need.

The Short Version

Hawaii has no inheritance tax. Heirs owe nothing to the state on what they receive. The estate itself may owe Hawaii estate tax if its gross value exceeds $5,490,000 — but that is the executor's obligation, paid before distributions are made. As a beneficiary, your tax exposure is limited to capital gains on appreciation after you inherit, and potentially HARPTA withholding if you sell inherited Hawaii real estate while living on the mainland.
