Hawaii vs Federal Estate Tax: Why You Might Still Owe

The federal exemption is roughly $15 million. Hawaii's is $5.49 million — frozen to a formula that predates the current federal law entirely.

Quick answer: yes — an estate can owe zero federal estate tax and still owe real money to Hawaii, potentially at the highest state estate tax rate in the country. Run your own numbers in the Hawaii estate tax calculator.

Two exclusions, deliberately disconnected

The federal estate tax exemption sits at roughly $15,000,000 per individual for 2026. Hawaii's own exclusion is fixed at $5,490,000 — a gap of about $9.5 million that federal law simply doesn't reach, but Hawaii still taxes at rates up to 20%.

Frozen by design, not by accident

Confirmed current: HRS §236E-6 computes Hawaii's exclusion using federal exclusion rules "as amended as of December 21, 2017", treating the decedent as if they died the day before the Tax Cuts and Jobs Act took effect. This isn't an oversight the legislature forgot to update — it's a deliberate statutory freeze that keeps later federal increases, including the current $15,000,000 exemption, from ever reaching Hawaii's own calculation.

Island real estate closes the gap fast

A primary home, a vacation condo on a neighbor island, retirement accounts, and a life insurance policy can add up quickly at Hawaii property values — pushing an ordinary estate past $5,490,000 well before it comes anywhere near the federal threshold, a genuinely common surprise for Hawaii families.

State vs federal — frequently asked questions

How much lower is Hawaii's exclusion than the federal exemption?

Hawaii's exclusion is $5,490,000, compared to a federal exemption of roughly $15,000,000 — a gap of about $9.5 million that federal law simply ignores but Hawaii does not.

Can an estate owe Hawaii tax but zero federal tax?

Yes, routinely. Any estate between $5,490,000 and $15,000,000 owes no federal estate tax at all, but can face a real Hawaii bill, potentially at rates up to 20%, the highest of any state.

Why doesn't Hawaii's exclusion rise along with the federal one?

Hawaii's exclusion formula is deliberately frozen to federal law as it stood just before the 2017 Tax Cuts and Jobs Act, so later federal increases — including the current $15,000,000 level — have no effect on the Hawaii number at all.

Why do ordinary Hawaii homeowners get caught by this gap?

A primary home, a vacation condo on another island, retirement accounts, and life insurance can add up quickly at Hawaii property values, pushing an estate past $5,490,000 well before it comes anywhere near the federal threshold.

Can I owe Hawaii estate tax even if I owe no federal estate tax?

Yes — an estate can owe zero federal estate tax and still owe real money to Hawaii, potentially at the highest state estate tax rate in the country.
