The $15 Million Estate Tax Exemption: What Permanence Actually Changes About Estate Planning

For the better part of a decade, estate planning conversations carried a countdown clock. The Tax Cuts and Jobs Act had doubled the estate and gift tax exemption in 2018, but with an expiration date: at the end of 2025, the exemption was scheduled to fall by half, dropping from $13.99 million per person back toward $7 million. Families near the line spent years making defensive moves, accelerating gifts, funding trusts, and locking in exemption they feared would vanish.

The One Big Beautiful Bill Act ended the countdown. Starting in 2026, the exemption is $15 million per person, $30 million per married couple, permanent, and indexed for inflation going forward. The 40% estate tax still exists above those amounts, but the cliff everyone was bracing for never arrived; the number went up instead.

Here’s the part most coverage misses: for the overwhelming majority of families, including most affluent ones, this quietly changed what estate planning is for. When almost nobody owes federal estate tax, the discipline doesn’t disappear. Its center of gravity moves, away from estate tax avoidance and toward income tax management, control, and protection. Families still running a 2012-era playbook are now often solving the wrong problem, and in some cases actively hurting their heirs. This piece covers what changed, what estate planning should focus on now, and who still genuinely has an estate tax problem.

What changed, precisely

Three facts define the new landscape:

The exemption is $15 million per person for 2026, indexed thereafter. That’s the amount anyone can transfer free of federal estate and gift tax, during life, at death, or in combination (the exemption is unified, so large lifetime gifts draw down what’s left at death). A married couple can shelter $30 million between them. Estates above the exemption face rates up to 40% on the excess.

It’s permanent, in the way tax law is ever permanent. There is no scheduled sunset, no countdown, no automatic reversion. What Congress makes, a future Congress can unmake, and that residual risk is worth respecting in long-horizon planning. But the era of racing a statutory deadline is over.

The annual gift exclusion continues alongside it. You can give $19,000 per recipient per year (2026) without touching the lifetime exemption at all. A married couple with three married children and six grandchildren can move over $450,000 a year to the family with zero paperwork against the exemption, before even counting direct payments of tuition and medical expenses, which don’t count as gifts at all when paid straight to the institution.

And one fact specific to our home state: Texas has no state estate or inheritance tax. For Texas families, the federal exemption is the whole conversation. (Families with property or heirs in other states may still touch state-level regimes, which is its own planning wrinkle.)

Put those together and the arithmetic is blunt: a Texas couple below $30 million of combined net worth, which is to say nearly every household we’ve ever met, now has no expected federal estate tax bill. So what’s all the planning for?

The new center of gravity: basis, not the estate tax

When the estate tax stops being the threat, the most valuable tax feature of death planning becomes the step-up in basis: assets you hold at death pass to heirs with their cost basis reset to fair market value, erasing every dollar of unrealized capital gain for income tax purposes. The rental property bought for $200,000 and worth $900,000, the brokerage account full of decades-old stock, the business built from nothing: held until death, the embedded gains vanish for your heirs. Sold or given away during life, they don’t.

This flips a generation of instinct on its head. The old playbook said get assets out of the estate, because everything in it was exposed to a 40% tax. The new reality for below-exemption families is closer to the opposite: the estate is now the most tax-favored place for appreciated assets to be at death, because inclusion costs nothing (no estate tax owed) and buys the step-up (gains erased). (One guardrail on the enthusiasm: retirement accounts are the exception. Traditional IRAs and 401(k)s never receive a step-up; their built-in income tax follows them to heirs as income in respect of a decedent, which is part of why required minimum distributions and lifetime drawdown planning matter so much.)

Texas families get a version of this benefit that most of the country doesn’t. Texas is a community property state, and community property receives a full step-up on both halves at the first spouse’s death, not just the deceased spouse’s half. A couple’s jointly built brokerage account or rental portfolio can have its entire embedded gain erased when the first spouse passes, leaving the survivor free to rebalance, diversify, or sell without capital gains tax. In common-law states, only half the basis resets at the first death. For our readers, this materially strengthens the case for patience with appreciated community assets, and it makes properly characterizing property as community or separate (something worth confirming with your estate attorney, especially for assets brought into the marriage or inherited) a planning task with real dollars attached.

The most common self-inflicted wound we see under the new rules follows directly: gifting low-basis assets during life. Give your daughter the $900,000 rental you bought for $200,000 and she takes it with your $200,000 basis; the $700,000 gain follows the gift and gets taxed when she sells. Hold it until death and the gain evaporates. For a family with no estate tax exposure, that lifetime gift converted a tax-free transfer into a future six-figure capital gains bill, in exchange for avoiding an estate tax they were never going to owe.

The refined version of the instinct: when giving during life makes sense (and it often does, for reasons that have nothing to do with taxes), give cash or high-basis assets, and hold the low-basis, highly appreciated ones. Which specific assets a family should hold to the end, and which are safe to move, is exactly the kind of question that belongs in a coordinated plan, because it interacts with the portfolio, the real estate, the business, and the charitable intentions all at once. (Highly appreciated assets earmarked for charity are a separate lane entirely; charity gets full value either way, which is why appreciated stock and donor-advised funds pair so well.)

Still worth doing: the unglamorous moves that matter

Portability, even when you “don’t need it.” When the first spouse dies, their unused exemption can transfer to the survivor, but only if the executor files an estate tax return (Form 706) to elect it, generally within a limited window after death. Skipping the filing because “we’re nowhere near the exemption” locks in today’s assumption about tomorrow’s facts: the survivor may live twenty more years, assets compound, a business may take off, and a future Congress may cut the exemption. The filing is cheap insurance that preserves up to $15 million of optionality. We lean toward making the election in nearly every first-death situation of consequence, precisely because its value shows up in the scenarios nobody predicted. (The estate tax return is also only one piece of what the first death changes about the survivor’s tax picture.)

Trusts, for the reasons trusts were always actually good at. With the tax motive receding for most families, trust design gets clearer, not obsolete: protecting an inheritance from a beneficiary’s creditors or divorce, managing money for minors or for heirs who aren’t ready, navigating blended-family dynamics, providing for a family member with special needs, and keeping a business’s ownership orderly. One tax note that now matters more, not less: trusts that retain income hit the top 37% bracket at just $16,000 of income in 2026, a brutally compressed schedule compared to individuals. Trust design and trust distribution policy have real income tax consequences even in a world without estate tax exposure, and old trusts drafted purely for estate tax avoidance deserve a fresh read against the new law. Families who made large defensive gifts into trusts before the feared 2025 sunset are, reasonably, now asking whether those structures still serve them; in some cases the answer involves modifying or decanting the trust to fit the world that actually arrived.

The basics the estate tax never touched. Beneficiary designations that actually match your intentions, current wills and powers of attorney, guardianship provisions, and a findable, organized picture of what you own. None of this was ever about the exemption, and all of it still determines whether a transition goes smoothly or becomes a mess. We covered the foundation in our piece on why a will alone isn’t enough; the new law makes that foundation more central to estate planning, not less, because for most families it now IS the estate plan.

Who still has a real estate tax problem

Permanence at $15 million doesn’t retire the estate tax for everyone. Three profiles still need the classic toolkit:

Owners of appreciating businesses. A company worth $8 million today growing at a healthy rate crosses $30 million of household net worth faster than intuition suggests, and the exemption’s inflation indexing won’t keep pace with a successful business. For founders, the estate plan and the exit plan are the same conversation: valuation timing, gifting interests while values are low, how a buy-sell agreement values the company at death, and, for C corporation founders, coordination with the QSBS exclusion that governs the income tax side of the same eventual sale. These families should be planning as if the exemption binds, because on their trajectory it will.

Families already near or above the line. For estates realistically approaching $15 million single or $30 million joint, the traditional levers all still work: annual exclusion gifting programs, direct tuition and medical payments, valuation-sensitive transfers, charitable structures, and life insurance owned outside the estate for liquidity. The difference under permanence is the luxury of sequencing these deliberately over years instead of cramming them ahead of a deadline.

Anyone planning across decades. The honest caveat we attach to every conversation: this exemption is a statute, and statutes change. A thirty-year plan built on the assumption that $15 million (indexed) survives every future Congress is a plan with a single point of failure. The practical middle path is to keep the flexibility that permanence now affords: make the portability election, keep trust structures adaptable, and revisit the plan at every major law change, the same discipline the 2025 scare should have taught everyone anyway.

Bringing it together

The estate tax, for the overwhelming majority of families, is over as a planning driver: $15 million per person, $30 million per couple, permanent and indexed, with no Texas state layer on top. What replaces it is a quieter and more universal discipline. Manage basis deliberately, because the step-up is now the biggest tax event in most families’ transfer plans, and lifetime gifts of appreciated assets are usually the wrong move. File for portability at the first death, because optionality is cheap and the future isn’t knowable. Keep trusts for what they’ve always done best: protection, control, and order, with an eye on their compressed income tax brackets. And keep the classic estate tax toolkit sharp for the families it still applies to: business owners on a growth trajectory and households genuinely near the line.

Estate planning didn’t get smaller when the exemption got permanent. It got more honest. The question stopped being “how do we beat the estate tax?” and returned to what it always should have been: what do you want your money to do for the people you love, and what’s the cleanest, lowest-tax path for it to get there?

Common Questions About the Estate Tax Exemption in 2026

What is the federal estate tax exemption for 2026?

$15 million per person, or $30 million for a married couple, under the One Big Beautiful Bill Act. The exemption is unified across lifetime gifts and transfers at death, is indexed for inflation in future years, and has no scheduled sunset. Estates above the exemption face federal estate tax at rates up to 40% on the excess. Texas imposes no state estate or inheritance tax on top of the federal system.

Did OBBBA make the estate tax exemption permanent?

Yes, in the statutory sense: the scheduled 2026 reduction (which would have cut the exemption roughly in half) was eliminated, and the new $15 million amount has no expiration date. The honest caveat is that any future Congress could change it again, which is why flexible structures and the portability election remain worthwhile even for families comfortably below the line.

Should I still make lifetime gifts if my estate is under the exemption?

Often yes, but for the right reasons and with the right assets. Gifts during life let you help family when it matters and watch the impact. The tax mistake to avoid is gifting highly appreciated, low-basis assets: the recipient inherits your basis and the built-in gain, while the same asset held until death would pass with a stepped-up basis and the gain erased. For below-exemption families, the general lean is to give cash or high-basis assets during life and hold the appreciated ones.

What is portability and should we file for it?

Portability lets a surviving spouse inherit the deceased spouse’s unused exemption, but only if the estate files a federal estate tax return electing it after the first death. Even for families nowhere near the exemption, we lean toward making the election: it’s inexpensive relative to what it preserves, and it protects against the scenarios you can’t predict, including future asset growth and future law changes that shrink the exemption.

Do we still need our trust now that the exemption is $15 million?

Maybe, but possibly for different reasons than it was drafted for. Trusts remain the right tool for creditor and divorce protection, minor or not-yet-ready beneficiaries, blended families, special needs planning, and business continuity. What deserves a fresh look is any trust built primarily to avoid an estate tax you no longer face, especially since trusts that retain income reach the top 37% bracket at just $16,000 of income in 2026. Older structures can often be modified or decanted to fit the current law.

Who still needs estate tax planning after OBBBA?

Primarily owners of appreciating businesses (whose net worth can cross $30 million faster than the indexed exemption grows), families already near or above the $15 million single or $30 million joint thresholds, and anyone whose plan spans enough decades that future law changes are a real risk. For those families, the classic toolkit still applies: annual exclusion gifts of $19,000 per recipient, direct tuition and medical payments, valuation-aware transfers, charitable structures, and liquidity planning, now with the breathing room to sequence it deliberately.
