Ask almost anyone about the estate tax and you’ll hear the same thing: that’s a problem for billionaires, not for me. For the federal version, that’s largely true. But there’s a quieter layer of “death taxes” sitting at the state level, and it reaches a lot further down the wealth ladder than most people assume — sometimes catching ordinary households with nothing more exotic than a paid-off house and a retirement account.
Here’s the part that surprises people most: in a handful of states, going one dollar over the limit can put your entire estate on the hook, not just the amount above the line. That mechanism has a nickname among planners — the “tax cliff” — and falling off it can quietly erase hundreds of thousands of dollars your heirs were counting on.
Let’s walk through how this actually works, which states to watch, and what families do to stay on the safe side of the edge.
First, A Quick Vocabulary Check
People use “estate tax” and “inheritance tax” interchangeably, but they’re two different animals:
- An estate tax is charged to the estate itself, before anything is handed out. The bill is settled out of the total pot, so heirs receive whatever’s left.
- An inheritance tax is charged to the people who receive the money, based on what they personally inherit and how closely related they were to the deceased.
There is no federal inheritance tax. There is a federal estate tax — but as you’ll see, it’s the least of most families’ worries.
The Federal Estate Tax: Big Threshold, Small Footprint
For 2026, an individual can pass roughly $15 million before the federal estate tax touches a dime — and a married couple can effectively shield around $30 million using a provision called portability. That figure isn’t a temporary perch, either. The 2025 tax law (the One Big Beautiful Bill Act) scrapped the long-feared “sunset” that would have cut the exemption roughly in half, and set $15 million as the new baseline going forward, indexed for inflation in later years.
Anything above the line is taxed on a sliding scale topping out at 40%. But because the threshold is so high, only a sliver of estates ever owe it — well under 1% of people who die in a given year. For the overwhelming majority of households, the federal estate tax is a non-event.
So if the federal tax is the wrong thing to worry about, what’s the right thing?
Where The Real Risk Lives: Your State
A dozen states plus Washington, D.C. levy their own estate tax — and here’s the catch that trips families up: state exemptions are often a fraction of the federal one. We’re not talking $15 million. In some states the line sits at $1–4 million, a range that a modest home, a 401(k), and a brokerage account can quietly add up to.
The states (plus D.C.) currently in this group:
Connecticut · District of Columbia · Hawaii · Illinois · Maine · Maryland · Massachusetts · Minnesota · New York · Oregon · Rhode Island · Vermont · Washington
A wealth adviser quoted in coverage of this issue put the problem plainly: in a low-threshold state, a single home can already account for most of the exemption. Layer in retirement savings and ordinary bank balances, and a family that never considered itself “rich” can land squarely in taxable territory — without ever changing their lifestyle. Years of rising home prices and market gains have only pushed more people toward that line.
The “Cliff” — Why One Dollar Can Cost a Fortune
Most taxes are marginal: you only pay on the portion above the threshold. Earn a dollar over a tax bracket and only that dollar gets taxed at the higher rate. Reasonable enough.
Cliff states throw that logic out the window for estates. Cross the exemption — even barely — and the tax applies to the whole estate, retroactively, from the first dollar. The exemption doesn’t shrink your bill; it vanishes entirely.
Picture two neighbors. One dies with an estate just under the limit and owes nothing. The other dies a hair over it and owes tax on everything. Same house, same street, wildly different outcome for the kids. That’s the cliff.
The Two Classic Cliff States
Illinois
- Exemption: $4 million
- Go over, and the estate is taxed in full, with progressive rates running up to roughly 16%.
New York
- Exemption: about $7.16 million
- New York softens the edge slightly with a buffer zone, but cross 105% of the exemption (roughly $7.5 million) and the entire estate becomes taxable. Top rates reach about 16%.
In both states, the gap between “owes nothing” and “owes a fortune” can come down to careful timing and structure — which is exactly why planning matters here more than almost anywhere else.
Low-Threshold States Worth Watching
Even outside the true cliff states, several places set the bar low enough to snare upper-middle-class families:
Oregon — the lowest in the nation at a $1 million exemption, with rates climbing from about 10% to 16%. In Oregon, a single appreciated home can blow past the line on its own.
Massachusetts — a $2 million exemption that isn’t adjusted for inflation, so it quietly captures more estates every year as values rise.
Washington — recently raised its exemption to $3 million for 2026 and pairs it with some of the steepest estate tax rates in the country.
Minnesota — a $3 million exemption with rates in the 13%–16% range.
The common thread: these limits were set years ago, and home values and investment balances have been marching upward ever since. Plenty of families have drifted toward the threshold without realizing the ground shifted under them.
Maryland: The State That Taxes Twice
Maryland earns its own section because it’s the only state that runs both an estate tax and an inheritance tax.
- The estate tax kicks in above a $5 million estate.
- On top of that, a 10% inheritance tax can apply when assets pass to more distant relatives or non-family beneficiaries — and the trigger for that one is shockingly low.
That one-two punch can take a serious bite out of what a niece, nephew, friend, or unmarried partner actually walks away with, even in cases where no estate tax is owed at all.
So What Can You Actually Do About It?
The honest answer from every professional who works in this space: plan early, and don’t improvise. Once someone has passed, the options shrink dramatically. The strategies that work are the ones put in place years ahead of time.
A few of the most common moves:
- Annual gifting. You can give up to $19,000 per recipient per year (2026) without touching your lifetime exemption — and married couples can double that. Done consistently across several heirs, this quietly drains a taxable estate over time.
- Irrevocable trusts. Properly structured, these remove assets from your taxable estate entirely. The trade-off is right there in the name: once it’s set, the terms and beneficiaries generally can’t be undone, so this is not a decision to rush.
- 529 education accounts. Funding a grandchild’s education can move money out of your estate while doing something genuinely useful with it.
- Charitable giving. Gifts to charity through a will or trust reduce the taxable estate and support causes you care about.
One caution worth repeating: this is not a do-it-yourself project once real money or a low-exemption state is involved. The people who navigate it well typically assemble a small team — an estate-planning attorney, a CPA, and a financial adviser who can see the whole picture and coordinate the moving parts.
The Bottom Line
The federal estate tax grabs the headlines, but for most families it’s a paper tiger. The genuine risk is local — a low state exemption, an unlucky cliff, and an estate that crept over the line through nothing more dramatic than a home that appreciated and a retirement account that did its job.
If you live in one of the dozen-plus states with its own death tax, it’s worth knowing exactly where you stand relative to the threshold now, while there’s still time to act. A few hours of planning today can be the difference between your heirs inheriting what you intended — and watching a meaningful slice of it disappear to a tax they never saw coming.
