Estate Tax Exemption for 2026: What OBBBA Made Permanent

For a person who dies during calendar year 2026, the basic exclusion amount is 15,000,000 dollars. That number was published in Revenue Procedure 2025-32 at section 4.14, the annual inflation release covering the 2026 tax year. The estate tax exemption 2026 figure is not a deduction anyone writes on a schedule. It is the total of lifetime taxable gifts plus taxable estate that may pass before federal transfer tax is owed, and it belongs to each decedent individually rather than to a married couple as a single pot. Public Law 119-21, the One Big Beautiful Bill Act enacted July 4, 2025, is the statute that set the 15,000,000 dollar level and directed that it be indexed for years after 2026.

The federal gift tax and the federal estate tax draw on one running total, so every taxable gift reported during life reduces what remains available at death. A 2026 plan therefore begins with a gift history, not with a balance sheet. Families who believe they have never filed a gift tax return sometimes have used part of the amount anyway, through below-market loans to children or transfers of closely held stock that nobody reported at the time. Reconstructing that record takes bank statements and entity documents, and the account information available through the IRS Get Transcript service can confirm which returns were actually filed and processed.

Here is the arithmetic on a real-sized estate. An unmarried business owner dies in October 2026 owning a closely held company appraised at 9,600,000 dollars plus a residence and marketable securities worth 8,800,000 dollars together, for a gross estate of 18,400,000 dollars. Debts and administration expenses of 900,000 dollars bring the taxable estate to 17,500,000 dollars. The 15,000,000 dollar exclusion available for a 2026 death shelters all but 2,500,000 dollars, and tax applies to that excess at the statutory rate in force for 2026. If the same owner had reported 3,000,000 dollars of taxable gifts in earlier years, only 12,000,000 dollars of exclusion would remain and 5,500,000 dollars would be exposed instead.

The mistake we correct most often is treating 30,000,000 dollars as an automatic married-couple number. Nothing about it is automatic. A surviving spouse picks up the first spouse’s unused portion only when the executor makes a portability election on a timely filed Form 706, and that return gets skipped constantly because the first estate looked too small to need one. A second frequent error is assuming a state follows the federal figure. A number of states run their own estate or inheritance tax with a far lower threshold, so a plan built around the federal amount alone can leave a state bill nobody budgeted for. Domicile drives that question, and a client who relocated late in life may leave two states arguing over which one gets to tax the estate.

Anyone whose net worth sits within a few million dollars of the line should have the plan measured against the 2026 number rather than against the figures a document assumed when it was signed years ago. Our team reads existing wills and trust instruments against current values through tax strategy consulting, and we coordinate the decedent’s final individual tax return with the estate filing so the two do not contradict each other. The Form 1040 instructions and Publication 17 cover the income tax side of the year of death. Because the amount indexes after 2026, the distance between a family’s net worth and the exclusion will keep moving, so a review every two years beats a one-time calculation.

Under prior law, the doubled exclusion was scheduled to sunset at the end of 2025 and fall back to a much smaller inflation-adjusted level for deaths on or after January 1, 2026. That deadline drove a large share of estate planning work from roughly 2018 onward. Advisers told clients to move assets out of the estate while the higher amount was available, on the theory that unused exclusion would simply vanish. Public Law 119-21, enacted July 4, 2025, repealed that sunset and fixed the amount at 15,000,000 dollars, and Revenue Procedure 2025-32 later published the 2026 figure as 15,000,000 dollars per decedent. The cliff never came.

The practical consequence is not that anything was lost. Exclusion used by a lifetime gift still counts against the same running total, so a taxpayer who gave away 12,000,000 dollars in 2024 has 3,000,000 dollars of the estate tax exemption 2026 amount left rather than nothing. What some families gave up was control. Assets moved into an irrevocable trust to beat a deadline that was later cancelled are still outside the donor’s reach, and in many cases those assets would have been covered by the exclusion anyway had they simply stayed put. That is a planning cost, not a tax cost, and it deserves an honest accounting.

Take a married couple with a combined net worth of 26,000,000 dollars in 2024. Acting on the sunset, each spouse gifted 6,000,000 dollars into a separate irrevocable trust, moving 12,000,000 dollars out of the taxable estates. In 2026 each spouse has a 15,000,000 dollar basic exclusion, so each retains 9,000,000 dollars of unused exclusion against a remaining combined estate of roughly 14,000,000 dollars plus growth. On these numbers the couple would have owed no federal estate tax without making the gifts at all. The trusts still deliver creditor protection and dynasty planning value, but the transfer tax rationale that justified them has weakened considerably.

The error we see now is running a gifting program on autopilot because a calendar said to. Annual six-figure transfers that made sense against a vanishing exclusion may now be moving low-basis property out of the estate for no transfer tax benefit while forfeiting a basis adjustment at death. The second error runs the other direction. Some clients now treat the 15,000,000 dollar level as untouchable. It sits in statute, and a statute can be amended by a later Congress, so a plan that only works at one exclusion level is a fragile plan regardless of which direction it leans.

A third pattern deserves a mention. Some families stopped planning altogether once the statute passed, reasoning that nothing below 15,000,000 dollars for 2026 needs attention. Life insurance owned inside the estate rather than by a separate trust still inflates the taxable figure at death. Retirement accounts payable to an estate instead of to named individuals still accelerate income tax for the people who inherit them. Neither of those problems has anything to do with the size of the exclusion, and both are cheaper to fix while the owner is alive.

Reviewing what was already done is the productive next step. We compare the basis of gifted holdings against current value using Publication 551, model what a sale inside the trust would report on Schedule D and Form 8949, and put the results next to the family’s cash needs in tax strategy consulting. Clean trust accounting through our bookkeeping group keeps the basis history intact for whoever administers the trust in twenty years. Since the amount indexes after 2026, the sensible cadence is to re-run this comparison whenever the inflation adjustment lands each autumn.

Directly, no. An irrevocable trust is irrevocable, and a completed gift cannot be pulled back because the tax rules moved in the donor’s favor afterward. That said, several tools exist for adjusting how the trust operates without unwinding it. State law in many jurisdictions permits decanting, which pours the assets of one trust into a new trust with better terms. Non-judicial settlement agreements among the trustee and beneficiaries can modify administrative provisions. A trust protector, if the document names one, may hold power to amend distribution standards or change situs. Which of these is available depends entirely on the governing instrument and the state whose law controls it.

The lever that matters most for tax purposes is the substitution power. Many irrevocable trusts drafted for grantor trust treatment give the donor the right to reacquire trust property by substituting other property of equivalent value. That power lets a family swap low-basis assets out of the trust in exchange for cash or high-basis holdings, bringing the appreciated property back into the taxable estate where it can receive a new basis at death. When the estate sits comfortably below the 2026 exclusion, that trade converts a future capital gain into no gain at all, at zero transfer tax cost.

One caution belongs with that power. The exchange has to be genuine, meaning the property going in is worth what the property coming out is worth on the date of the swap, supported by an appraisal for anything without a public market price. A trustee who rubber-stamps a lopsided exchange invites a challenge from a beneficiary years later, and the tax result is only as good as the valuation sitting behind it. Document the transaction at the time, not during the estate administration.

Consider a trust holding founder stock with a 400,000 dollar basis now worth 2,500,000 dollars. Left in the trust, the beneficiaries take the carryover basis, and a sale after the grantor’s death reports about 2,100,000 dollars of gain. If the grantor instead exercises the substitution power, contributing 2,500,000 dollars of cash or high-basis securities and taking back the stock, that stock is in the estate at death. With a taxable estate of, say, 9,000,000 dollars, the entire amount falls under the 15,000,000 dollar exclusion for a 2026 death. No federal estate tax is due, and the basis adjustment removes the built-in gain. The family trades unused exclusion for a permanent income tax saving.

The failure point is records. Basis for gifted property carries over from the donor, and nobody at the IRS reconstructs it for a family fifteen years later. We regularly meet trustees holding appreciated stock with no idea what the donor paid. Keep the original purchase records and appraisals with the trust file, along with any gift tax returns, following the standards in the IRS guidance on recordkeeping and the basis rules in Publication 551. A second mistake is treating the income tax a grantor pays on trust income as an additional taxable gift. Under current rules it is not, which is part of why grantor trusts remain useful.

Trust income that reaches beneficiaries flows through a Schedule K-1 and lands on the beneficiary’s Schedule E, so the trust’s investment choices affect five or six individual returns at once. We map that flow in tax strategy consulting and keep the underlying ledgers current through bookkeeping so distributions are reported the same way by everyone involved. Ask your attorney to read the instrument for a substitution power and a protector clause before the next distribution cycle, because those two provisions decide how much flexibility the family actually carries into 2027.

The annual gift tax exclusion for 2026 is 19,000 dollars per donee, published in Revenue Procedure 2025-32. Gifts that fit inside it are ignored for transfer tax purposes. They do not consume any part of the 15,000,000 dollar basic exclusion available for a 2026 death, and in most cases they do not require a gift tax return at all. This is the quiet workhorse of estate planning, because it moves value plus all future appreciation out of the estate every single year without any lifetime exclusion being spent.

The exclusion is measured per donor and per recipient, so a married couple can each give 19,000 dollars to the same person in 2026. When one spouse writes the whole check from a separate account, treating half as coming from the other spouse requires a gift-splitting consent on a gift tax return for that year, which is a filing many couples overlook because the money came out of what they think of as joint funds. Payments made directly to a school for tuition or directly to a provider for medical care sit outside the gift tax entirely and do not count against the 19,000 dollar figure.

Run the numbers for a couple with four married children. That is eight donees. Each parent gives 19,000 dollars to each donee, so 38,000 dollars per donee, and 304,000 dollars leaves the estate in calendar 2026 with no gift tax return required for the annual exclusion gifts themselves. Sustained for ten years, more than 3,000,000 dollars of principal moves out, along with every dollar those assets earn afterward. None of it touches the 15,000,000 dollar exclusion, which stays fully intact for the taxable estate or for a larger lifetime transfer later on.

Two errors show up repeatedly. The first is writing the tuition check to the student rather than to the institution. Paid to the student, it is an ordinary gift that eats into the 19,000 dollar allowance. Paid to the registrar, it is excluded without limit. The second is assuming a gift into a trust automatically qualifies. Annual exclusion treatment requires a present interest, which trusts usually create through withdrawal rights and the notices that go with them, and a trustee who stops sending those notices can quietly convert every future contribution into a taxable gift. Funding gifts from a retirement account creates its own problem, since the withdrawal is taxable income reported to the account owner on Form 1099-R before a single dollar reaches the child.

Timing is measured by delivery rather than by intent. A gift by check counts when the recipient deposits it and the bank pays it, so a December check that clears in January belongs to the later year and uses the later year’s allowance. Wire transfers and transfers of stock settle on their own schedules, which is why we push clients to finish the year’s gifts well before the holidays rather than during the last week of December.

Sequencing matters more than size. Distribution rules for inherited retirement accounts are set out in Publication 590-B, and for many families a retirement account is the worst asset to give away during life and the best one to leave to charity at death. Education funding through a qualified tuition program interacts with the credits and deductions described in Publication 970, so the gift and the tax benefit should be planned as one decision. We build that order of operations in tax strategy consulting and report the results on the donors’ individual tax returns. Set the 2027 gifting calendar in January rather than in December, because a check that clears after year end lands in the wrong annual exclusion.

Portability lets a surviving spouse add the deceased spouse’s unused exclusion to their own. It is not automatic and it is not a default. The executor of the first spouse’s estate has to elect it on a timely filed Form 706, the federal estate tax return, even when that estate is nowhere near large enough to owe any tax. No return means no election, and no election means the first spouse’s unused amount disappears. This single procedural step is the most valuable item on the checklist for a surviving spouse in 2026.

Portability applies to the basic exclusion amount only. The generation-skipping transfer tax exemption is not portable between spouses, so a family planning transfers to grandchildren has to allocate that exemption during life or through the estate return rather than relying on a surviving spouse to inherit it. Once elected, the ported amount is fixed in dollars at the first death. It does not grow with later inflation adjustments, while the survivor’s own basic exclusion continues to index under the statute, so the two halves behave differently over time.

Work through the arithmetic. A husband dies in March 2026 having used 4,000,000 dollars of exclusion on lifetime gifts. His unused portion is 11,000,000 dollars of the 15,000,000 dollar amount available for a 2026 death. His executor files Form 706 and elects portability. If the surviving wife also died later in 2026, she would apply her own 15,000,000 dollars plus his ported 11,000,000 dollars, sheltering 26,000,000 dollars. If she instead lives another fifteen years, her own exclusion will be whatever indexed figure applies in the year she dies, while his 11,000,000 dollars stays frozen at that number. Had the executor skipped the return, the family would have 15,000,000 dollars to work with instead of 26,000,000 dollars.

The common mistake is exactly the one described above, and it usually starts with a well-meaning adviser telling the family that no return is required because the estate falls below the filing threshold. That advice answers the wrong question. The second trap is remarriage. A survivor carries the unused exclusion of the last deceased spouse, so a widow who remarries and outlives the second husband can lose the first husband’s ported amount if the second estate makes no election. Anyone who has remarried should have both estates reviewed before assuming the earlier election still helps.

There is limited relief for executors who miss the deadline. The IRS has published a procedure that lets certain estates with no filing obligation apart from portability itself make a late election within a defined window measured from the date of death. That relief carries conditions and it does not stay open forever, so a family that has only just learned about the election should have the first estate reviewed quickly rather than assuming the door has closed or assuming it will remain open indefinitely.

Handling the first estate well makes the second one manageable. We obtain authority to speak with the IRS using Form 2848, pull filed-return records with Form 4506-T when the gift history is incomplete, and read any correspondence against the IRS guidance on understanding your notice or letter so a request for information does not turn into a missed deadline. That work sits alongside the surviving spouse’s individual tax return and the longer-range modeling we do in tax strategy consulting. Families who want this arithmetic run against their own balance sheet can request a consultation with our team. Whatever the exclusion becomes after its next indexing adjustment, an election preserved today keeps the option open.
