State Estate & Inheritance Tax Guide
Eighteen states tax estates or inheritances in 2026, some from $1 million. Which states, how the cliff rules bite, and why spousal portability will not help.
Most Americans will never pay a federal estate tax — the 2026 federal exemption is $15 million per person, permanently raised by the One Big Beautiful Bill Act (OBBBA) signed July 4, 2025. But state-level death taxes are a very different story. With exemptions as low as $1 million, millions of middle-class families in high-cost states face real exposure they may not even know about.
Estate Tax vs. Inheritance Tax: What's the Difference?
These two taxes are often confused, but they work very differently — and both can apply to the same transfer of wealth.
Iowa fully repealed its inheritance tax effective January 1, 2025. If you're an Iowa resident or beneficiary, you no longer owe state inheritance tax on assets received from an Iowa decedent.
Which States Have These Taxes?
As of 2026, 12 states plus the District of Columbia impose an estate tax, while 5 states impose an inheritance tax. Maryland imposes both. That means 33 states — including Florida, Texas, California, and most of the South and Mountain West — have neither tax.
The states with the most aggressive tax regimes are generally in the Northeast and Pacific Northwest. Oregon has the nation's lowest exemption at just $1 million — unchanged for over a decade. With the federal exemption now at $15 million per person in 2026, the gap between federal and many state thresholds is wider than it has ever been, and middle-class families in high-cost states are increasingly exposed.

Watch Out for "Cliff" Rules
Two states have particularly punishing provisions called "cliff" rules that can catch estates by surprise:
Cliff rules make estate planning in Massachusetts and New York especially time-sensitive. Strategies like annual gifting, irrevocable trusts, or charitable giving can help keep an estate below the threshold. Work with an estate planning attorney before assuming the exemption is a safe threshold.
No Spousal Portability at the State Level
Under federal law, a surviving spouse can "port" their deceased spouse's unused federal exemption — effectively doubling the federal exemption for married couples to $30 million in 2026. Most states do not offer this portability.
This is one of the most overlooked estate planning traps. A married couple with $8 million in total assets in Washington State might assume they're fine — but without proper planning using tools like a credit shelter trust, the surviving spouse's estate could face significant state estate tax upon their own death.
Washington State: Two Major Changes in Two Years
Washington has had more estate tax upheaval in the past 18 months than in the previous decade. Here's the full picture:
- July 1, 2025 (SB 5813): Exemption raised from $2.193M to $3 million; top marginal rate dramatically increased from 20% to 35% on estates over $9 million — briefly making Washington the highest estate tax rate in the nation.
- July 1, 2026 (SB 6347): Governor Ferguson signed a rollback, reducing the top rate back to 20%. The $3 million exemption is retained but is now effectively frozen (not inflation-indexed going forward).
The net result for 2026: the exemption is a meaningful improvement over the old $2.193 million, but the rate structure returns to the pre-2025 graduated scale of 10%–20%. Washington still has no spousal portability, and no state income tax — making it a nuanced state for high-net-worth planning.
6 Strategies to Reduce Your Estate Tax Exposure
If you live in a state with an estate or inheritance tax — or own property in one — there are meaningful steps you can take to protect your heirs. None of these are loopholes; they're legitimate planning tools used by estate attorneys every day.
Annual Gift Tax Exclusion
Give up to $19,000 per recipient per year (2026 federal limit) without triggering gift tax. Over time, annual gifting can meaningfully reduce your taxable estate — and there's no state gift tax in most jurisdictions. Connecticut is the only state with its own gift tax (exemption matches the federal threshold).
Credit Shelter / Bypass Trusts
Since most states don't offer spousal portability, a credit shelter trust lets the first spouse to die "use" their state exemption — effectively doubling the exemption for the couple without relying on portability.
Irrevocable Life Insurance Trust (ILIT)
Life insurance death benefits paid to an ILIT are removed from your taxable estate. This is a powerful tool for estates that need liquidity to pay estate taxes without selling assets. The ILIT is also used to fund the estate tax bill itself.
Charitable Giving & Trusts
Charitable bequests reduce your taxable estate dollar-for-dollar. Charitable remainder trusts (CRTs) and donor-advised funds can also provide income during your lifetime while reducing estate exposure.
Qualified Family Business Deductions
States like Minnesota and Washington offer enhanced deductions for qualifying family-owned businesses and farms. These can shelter millions in value from estate tax while keeping the business in the family.
Domicile Planning
Where you're legally domiciled matters enormously. Relocating to a state with no estate tax — and properly establishing domicile before death — is one of the most effective strategies for high-net-worth individuals.
One of the most practical ways to address an estate tax liability is with a life insurance policy held inside an ILIT. The death benefit provides your heirs with liquidity to pay the estate tax bill — so they don't have to sell the family home, business, or investments. Quote-Bot can help you find and apply for coverage in minutes.
Don't Forget About Nonresident Exposure
Estate taxes typically apply not only to residents of a state, but also to nonresidents who own property in that state. If you live in Florida (no estate tax) but own a vacation home in Oregon or Maine, your estate may owe state estate tax in those states — even though your home state has no such tax.
This is an often-overlooked planning need. Life insurance held in an ILIT can provide the liquidity needed to pay state estate taxes on out-of-state property without forcing heirs to sell the asset.
