2026 Estate Tax Exemption: The $15M Cliff That Vanished

Updated July 3, 2026

For three years, estate planners sold a deadline. On January 1, 2026, they warned, the federal estate tax exemption would fall off a cliff — sliced roughly in half, dragging millions of dollars of family wealth back into taxable territory. Trusts were drafted. Gifts were rushed. Then the cliff got paved over.

Instead of dropping, the exemption climbed. Beginning in 2026, each individual can shield $15,000,000 from federal estate and gift tax — up from $13,990,000 in 2025 (IRS Revenue Procedure 2025-32). A married couple can now move up to $30,000,000 between them. And unlike the old rules, this number carries no expiration date.

The interesting story isn't the cliff. It's that most planning content still describes a reversion that no longer exists in law — and that a family comfortably under the $15 million federal line can still get hit by a tax bill the federal headlines never mention.

The Cliff That Never Happened

Here's the math that scared everyone. The 2017 Tax Cuts and Jobs Act (TCJA) roughly doubled the estate tax exemption, but it wrote in an expiration: at the end of 2025, the doubling would lapse, and the exemption would revert to its pre-2017 base of about $5 million per person, adjusted for inflation. By 2026, that inflation adjustment would have landed the figure around $7 million, by most pre-OBBBA projections (estimates ran roughly $6.8M–$7.2M) (citizensbank.com; dglaw.com).

So an individual sitting at the 2025 exemption of $13,990,000 was staring at a potential overnight haircut of nearly $7 million in shelter — and at a 40% rate, that gap represented roughly $2.8 million in tax that planning was racing to lock in before the deadline.

Then the law changed. OBBBA repealed the scheduled sunset outright and reset the baseline at $15 million per person for 2026 (morganlewis.com; pierceatwood.com). The IRS formally codified the figure in Revenue Procedure 2025-32, released in October 2025 (currentfederaltaxdevelopments.com; taxnotes.com).

The takeaway most articles miss: the "what if you don't act before 2026" framing is now obsolete. The exemption didn't shrink. It grew by about $1.01 million per person in a single year, and the deadline that drove three years of urgency simply expired without consequence.

What "Permanent" Actually Means

"Permanent" in tax law is a specific word, not a promise. It means the $15M exemption has no scheduled expiration date written into the statute — unlike the TCJA version, which self-destructed on a calendar date (hselaw.com; beankinney.com).

What it does not mean is "unchangeable." Congress can lower the exemption any time it passes a new law and the President signs it. A future administration could cut it back to $5M or $10M with a single bill. The difference is that the cut would now require affirmative legislation — it won't happen automatically while everyone looks away.

There's also a built-in raise. Starting in 2027, the $15M amount indexes to inflation annually, using 2025 as the base year (Public Law 119-21; IRC §2010(c)(3)). So absent new legislation, the exemption only moves in one direction: up. For 2026 specifically, the estate, gift, and generation-skipping transfer (GST) exemptions are all unified at the same $15M figure (IRC §2631).

The 2026 Numbers You Actually Need

The estate exemption gets the headlines, but it travels with a cluster of related limits that changed — or pointedly didn't — for 2026. If you're doing any gifting this year, these are the figures that govern the paperwork.

Two of these deserve a second look.

The annual gift exclusion held flat at $19,000 per recipient (IRS). That's the amount you can give any one person in 2026 without touching your lifetime exemption or filing a gift tax return. A couple can combine theirs to move $38,000 to each child, grandchild, or friend — and there's no limit on the number of recipients. Inflation didn't bump it this year because the exclusion only rises in $1,000 increments and the underlying index hadn't crossed the threshold.

The noncitizen-spouse exclusion matters because gifts between spouses are normally unlimited — but only when the receiving spouse is a U.S. citizen. If your spouse isn't, you're capped, and that cap rose to $194,000 for 2026 (IRS Rev. Proc. 2025-32). It's a narrow rule that catches a surprising number of mixed-citizenship households off guard.

The State-Level Cliff Nobody Mentions

Here's the insight buried under the federal celebration: the $15M federal exemption does nothing for your state estate tax.

Twelve states plus the District of Columbia levy their own estate tax, and five states levy a separate inheritance tax — Maryland is the only state with both — and several set their exemptions far below the federal threshold, in some cases starting near $1 million (pierrolaw.com; harrisbeachmurtha.com). A family that's nowhere close to the federal line can still owe a state.

Consider a worked example. Say you live in a state with an estate tax exemption around $2 million and you die with a $4 million estate — a paid-off house, a retirement account, and a brokerage balance that's hardly dynastic wealth.

• Federal estate tax: $0. You're $11 million under the $15M exemption.
• State estate tax: in a state like Massachusetts — a $2 million exemption with graduated rates topping out at 16% — a hypothetical bill potentially well into six figures, because your taxable estate exceeds the state threshold by roughly $2 million, and state rates climb on a graduated scale.

The number gets worse in "cliff" states. New York, for example, is known for an estate tax structure where exceeding the exemption by more than a small margin can pull the entire estate into tax — not just the amount over the line (thevillagelawfirm.com). Cross the threshold by a few percent and you can owe tax on the whole thing, which is the genuine cliff still operating in 2026 — just at the state level, where almost no one is looking.

If your estate is comfortably under $15M, federal planning is largely solved. Your real homework is figuring out whether your state taxes estates, where its exemption sits, and whether it has one of those cliff provisions. That single question now matters more for most middle-and-upper-middle-class families than anything in the federal code.

The $30M Couple Trap: Portability Isn't Automatic

The $30 million married-couple figure comes with a string attached that quietly trips up grieving families.

When the first spouse dies, their unused exemption doesn't transfer to the survivor on its own. To capture it — the so-called Deceased Spousal Unused Exclusion, or DSUE — the surviving spouse (through the estate's executor) must elect portability by filing a federal estate tax return, Form 706 (IRC §2010(c)). And here's the catch: that return is required even when no estate tax is owed and no return would otherwise be necessary.

Miss the filing, and the first spouse's $15M exemption can simply evaporate. The survivor is left with only their own $15M instead of the combined $30M, and the difference can resurface as a 40% tax bill when the second spouse dies.

The deadline is generous but firm: the estate generally has 9 months from the date of death to file, extendable to 15 months. The IRS also offers a simplified late-election relief window for estates that weren't otherwise required to file — but relying on relief is a worse plan than filing on time. If you're newly widowed and your combined assets are anywhere near the exemption, filing that 706 is the highest-leverage paperwork you'll handle all year, even if it feels pointless because nothing is owed today.

How We Analyzed This

This is a data study built entirely on published primary sources and legal analysis — no client data, no projections of our own beyond arithmetic on stated figures.

The exemption amounts come from IRS Revenue Procedure 2025-32 (released October 2025), which codified the 2026 inflation-adjusted transfer tax figures, cross-checked against the IRS's own 2026 inflation-adjustment newsroom release reflecting the OBBBA amendments (irs.gov). The legislative history — that OBBBA was signed July 4, 2025 as Public Law 119-21 and repealed the TCJA sunset — is drawn from law-firm analyses published after enactment (morganlewis.com; pierceatwood.com; dglaw.com).

For the "feared cliff" figure, we used the pre-OBBBA scheduled reversion described by financial institutions tracking the sunset: a return to the ~$5M TCJA base plus inflation, landing near $7M for 2026 (citizensbank.com; dglaw.com). The federal-vs-state comparison relies on state-tax surveys and estate-planning firm summaries (pierrolaw.com; harrisbeachmurtha.com; thevillagelawfirm.com).

Our analytical approach: hold the actual 2026 law side by side with the reversion that was scheduled but never took effect, quantify the gap, and then test where the $15M federal exemption stops protecting a family — which is where the state-level analysis takes over. Dollar figures in the worked example are illustrative and depend on your specific state's rate schedule.

What the Data Shows

Three findings stand out once the numbers are laid against each other.

First, the urgency narrative collapsed. The exemption didn't fall by ~$7M — it rose by about $1.01 million per person. Any planning premised on a 2026 reversion is now solving a problem that doesn't exist. The roughly $2.8 million of tax that aggressive 2025 gifting raced to lock in (the ~$7M gap at 40%) was, for most families, never at risk.

Second, the federal problem got smaller while the state problem stayed exactly the same size. With the federal line at $15M, the overwhelming majority of American estates owe zero federal estate tax. But the states with ~$1M–$2M exemptions didn't budge in response to OBBBA. For a $4M estate, the entire tax exposure is now a state question — and in cliff states, the geometry is brutal.

Third, the couple's $30M is conditional, not guaranteed. The combined exemption only holds if the surviving spouse files Form 706 to elect portability on time. The gap between "did the paperwork" and "didn't" is, at the extreme, $15M of exemption — about $6 million of potential tax at the 40% rate. That's the most expensive missed deadline in the entire estate code, and it lands on people who often don't know it exists.

The pattern: the federal cliff was real until July 2025, then it wasn't. The state cliff and the portability cliff were never repealed — and now that the federal scare is over, they're the only cliffs left standing.
