The $15 Million Estate Exemption Is Now Permanent: What That Changes for Your Plan

For most of the last several years, the message to families with meaningful wealth was some version of "hurry." The federal estate tax exemption was scheduled to fall roughly in half at the end of 2025, and advisors urged clients to make big gifts, fund trusts, and lock in the high limits before they disappeared. A lot of people did exactly that, often under real time pressure. And then the deadline they were racing simply vanished. The 2026 law didn't let the exemption drop. It raised the number and removed the expiration date. The $15 million estate exemption is now permanent, and that quiet reversal changes the planning conversation more than most families realize.
That's genuinely good news. But it also leaves a lot of people holding plans built for a world that no longer exists. Moves that made sense as a race against a sunset can look different in the calm that followed. So the real question isn't "what happened" — it's what actually changes for your plan now that the clock is gone.
The deadline that disappeared
Under the 2017 tax law, the exemption had climbed to roughly $14 million per person by 2025, but it carried a built-in expiration: on January 1, 2026, it was set to revert to somewhere around $7 million. That looming cut is what drove years of urgent gifting.
Instead, the One Big Beautiful Bill Act set the exemption at $15 million per person — $30 million for a married couple — and made it permanent, indexed for inflation. The annual gift tax exclusion sits at $19,000 per recipient for 2026. One honest note on the word "permanent": it means there's no scheduled sunset written into the law, not that a future Congress can never touch it. The artificial 2025 deadline is what's gone — and that alone reshapes how a plan should be built.

From racing a clock to choosing calmly
The biggest shift is one of posture. Almost every aggressive move of the last few years — large gifts to irrevocable trusts, giving away appreciated assets, using up exemption "before it's gone" — was justified partly by the deadline. Take the deadline away, and each of those decisions has to stand on its own merits.
For many families, that changes the math in a specific and welcome way. When you gift an asset out of your estate during your life, the recipient generally keeps your original cost basis. When an asset instead passes at your death, it usually gets a step-up in basis to its value on that date, which can erase a lifetime of built-up capital gains for your heirs. Under the old sunset pressure, giving assets away early to beat the cliff often won out. Now, for an estate comfortably under $15 million per person, holding the asset and letting heirs receive the step-up is frequently the smarter outcome — because there's no estate tax to plan around and no deadline forcing the gift.
None of this means gifting is wrong. It means the reflex to gift early, purely to escape a vanishing exemption, deserves a fresh look. The most useful exercise this year is to re-run each large gift you're considering against the "just hold it and let it step up" alternative, and let the numbers rather than a countdown make the call.
Plans built for the sunset deserve a second read
If you set up a trust or made a large gift specifically to beat the 2025 deadline, this is the year to revisit what you built. The good news first: gifts you already completed under the higher exemption are safe. The IRS confirmed years ago, through its anti-clawback rule, that using the temporarily higher exemption wouldn't be penalized if the number later fell — and now that the exemption is permanently higher, that worry is fully off the table. You don't need to unwind a completed gift.
What does deserve attention is whether the structures still fit your life. Couples who each set up a spousal lifetime access trust, for example, sometimes made them look too similar in a hurry — and trusts that mirror each other too closely can be pulled back into both estates under the reciprocal trust doctrine. That's a fixable problem, but only if someone looks. The theme is consistent: the strategies aren't broken, but the urgency that shaped them is gone, and a calm review often finds a cleaner version of the same plan.
Whether the permanent exemption simplifies your plan or leaves real work to do depends on your estate's size, your state, and the moves you already made under the old deadline. A Clarity Call is a good place to take a fresh, unhurried look.

Portability isn't automatic — and it's the return you shouldn't skip
Here's a piece of the permanent exemption that quietly trips up families. A married couple can shelter up to $30 million, but only if they preserve both spouses' exemptions through portability — and portability is not automatic. To carry a deceased spouse's unused exemption forward, the surviving spouse's representative has to elect it by filing a federal estate tax return (Form 706), even when the estate owes no tax at all and would otherwise never file.
Skip that filing, and the unused exemption is gone for good. It's one of the most common and most expensive oversights in this whole area, precisely because it feels unnecessary — the estate isn't taxable, so why file? The answer is that filing is what locks in the second $15 million for later. If you've lost a spouse in the last few years, or you're planning as a couple now, this is worth putting on the calendar rather than assuming it takes care of itself. One related caution: unlike the estate tax exemption, the generation-skipping transfer tax exemption is not portable between spouses, so it has to be allocated deliberately rather than inherited.
Your state may tax what the federal government won't
A $15 million exemption sounds like it puts estate tax out of reach for almost everyone. At the federal level, for most families, it does. But the federal number isn't the whole story. Twelve states levy their own estate tax and several more impose an inheritance tax, and their thresholds sit far below the federal line — Oregon starts at $1 million and Massachusetts at $2 million, with several others between there and a few million dollars.

That gap matters. A family that's comfortably under the federal exemption can still owe a meaningful state estate tax, and a lot of people never think to check because the federal headline told them they were clear. If you live in — or own property in — a state with its own estate or inheritance tax, that's where the real planning conversation often is now. State estate taxes can frequently be deducted against the federal taxable estate, but the better move is usually to plan around the state threshold in the first place, not to absorb the bill.
For estates still above the line, generosity still does real work
For the smaller group of families whose estates sit above $15 million per person, the toolkit hasn't changed — and charitable strategy still does some of the heaviest lifting. Estates above the exemption face a 40% federal tax on the excess, which means every dollar you can thoughtfully move out of the taxable estate is a dollar that isn't taxed at that rate. A charitable lead trust can pass wealth to heirs at a reduced transfer-tax cost while supporting causes along the way. A donor advised fund or an outright charitable gift can shrink the taxable estate directly. Well-structured giving turns a portion of what would have gone to Washington into support for the people and missions you actually care about.
This is also the quiet opportunity inside the permanent exemption. With the deadline gone, charitable planning no longer has to be jammed into a year-end scramble. It can be built patiently, as part of how a family thinks about the larger wealth transfer already underway — matching generosity to values instead of to a tax cliff.
Permanent doesn't mean finished
The real risk of a permanent exemption isn't a tax bill. It's relief curdling into neglect. When the artificial 2025 deadline vanished, it became tempting to file estate planning under "handled" and move on. That would be a mistake, because estate planning was never only about the federal estate tax. Making sure assets pass smoothly, minimizing income tax for your heirs, protecting a surviving spouse, preserving the step-up, filing for portability, watching the state threshold, and directing your wealth toward the people and causes you choose — none of that went away when the deadline did.
Life keeps moving even when the law sits still. Marriages, births, deaths, a business sale, a big change in net worth — each one is a reason to look again. The families who handle this well treat the permanent exemption exactly for what it is: good news that removes a deadline, not the work. Use the calmer environment to plan well. That's the opportunity in front of you this year.
Estate planning depends on your assets, your state, and your goals, and the details are where good plans are won or lost. The conversations that move people from "interesting article" to "actual decision" happen one set of numbers at a time — your estate, your real figures, an honest read.
