Trusts are not automatically exempt from estate tax. Whether the federal estate tax reaches property held in trust depends on the type of trust: assets in a properly structured irrevocable trust are generally excluded from the grantor’s taxable estate, while assets in a revocable living trust are fully included. And for 2026, the tax only touches estates above $15,000,000 per individual to begin with, so most people never face it regardless of how their assets are titled.1Internal Revenue Service. What’s New — Estate and Gift Tax
Why Revocable Living Trusts Don’t Reduce Estate Tax
A revocable living trust does nothing for federal estate tax. Because the grantor keeps the power to change the trust, move assets in and out, or dissolve it entirely, the IRS treats every dollar inside the trust as part of the grantor’s personal estate. When the grantor dies, the trustee reports those assets on the estate tax return alongside everything else the decedent owned.2Internal Revenue Service. Instructions for Form 706
The flexibility that makes a revocable trust attractive is what disqualifies it from estate tax savings. The grantor typically serves as trustee, controls distributions, and can change beneficiaries at will. That level of control means ownership never truly left.
Revocable trusts still do useful work. They let heirs skip probate, which can be slow and expensive, and they keep the distribution of assets private, since probate records are generally public. Those are real benefits. They are not, however, tax benefits. Probate avoidance and estate tax reduction are separate goals, and a revocable trust achieves the first but not the second.
When Irrevocable Trusts Keep Assets Out of the Estate
Assets placed into an irrevocable trust are generally excluded from the grantor’s taxable estate because the transfer of ownership is legally final. The grantor gives up the right to change the trust terms, take the property back, or direct how it is used. That complete separation is what keeps the assets outside the gross estate at death.
The separation has to be real. Federal law pulls the property back into the taxable estate if the grantor kept the right to income from it or the power to decide who benefits from it.3Office of the Law Revision Counsel. 26 USC 2036 – Transfers With Retained Life Estate The same result follows if the grantor held any power to alter or revoke the trust at death.2Internal Revenue Service. Instructions for Form 706 Serving as trustee with broad discretion over distributions can trigger the same inclusion, because the IRS looks at practical control rather than the trust’s label.
The trust must also avoid giving the grantor a reversionary interest — a possibility that the assets could return to the grantor — worth more than five percent of the trust property’s value. Above that threshold, the grantor is treated as the owner of that portion for tax purposes.4Office of the Law Revision Counsel. 26 USC 673 – Reversionary Interests
Life Insurance and the Three-Year Rule
Transferring a life insurance policy into an irrevocable life insurance trust is a common way to keep the death benefit out of the taxable estate. But if the grantor held any ownership rights over the policy — such as the power to change beneficiaries, borrow against it, or cancel it — the full proceeds are included in the gross estate.5Office of the Law Revision Counsel. 26 USC 2042 – Proceeds of Life Insurance
Even after transferring the policy cleanly, the grantor has to live at least three more years. If death comes within that window, the full death benefit is pulled back into the gross estate.6Office of the Law Revision Counsel. 26 USC 2035 – Adjustments for Certain Gifts Made Within 3 Years of Decedent’s Death The rule blocks last-minute transfers meant to sidestep the tax.
The Step-Up in Basis Trade-Off
Removing assets from the taxable estate is not always the smart move, and this is where many people are surprised. Assets included in a decedent’s gross estate generally receive a “stepped-up” basis: their value for capital gains purposes resets to fair market value at the date of death. When heirs sell later, they pay capital gains tax only on appreciation after the death, not on the lifetime gain.7Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent
Assets in a revocable trust qualify for that step-up because they are in the gross estate. Assets in an irrevocable grantor trust that successfully removes them from the estate do not. The IRS confirmed this in Revenue Ruling 2023-2: when trust assets are not included in the decedent’s gross estate, they do not count as property “acquired from a decedent,” and the basis stays at what the grantor originally paid.8Internal Revenue Service. Revenue Ruling 2023-2
The math can be striking. Say a grantor bought property for $200,000 and transferred it to an irrevocable trust when it was worth $500,000. If it is worth $800,000 at the grantor’s death and a beneficiary later sells for $900,000, the beneficiary owes capital gains tax on $700,000 — the sale price minus the original $200,000 basis. Had the property sat in a revocable trust, the basis would have reset to $800,000 at death, leaving only $100,000 of gain when sold. For estates well below the $15,000,000 exemption, aggressively removing appreciated assets through an irrevocable trust can create a bigger tax bill than it prevents.
The 2026 Exemption and Portability Between Spouses
The federal estate tax only applies to estates above the basic exclusion amount. For 2026, that threshold is $15,000,000 per individual, up from $13,990,000 in 2025.9Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments From the One, Big, Beautiful Bill Amounts above the exemption are taxed at graduated rates topping out at 40%. The One, Big, Beautiful Bill Act, signed on July 4, 2025, set the $15,000,000 level and indexed it for inflation going forward, replacing the Tax Cuts and Jobs Act provisions that had been scheduled to expire at the end of 2025.10U.S. Department of the Treasury.

Married couples can combine exemptions through portability, sheltering up to $30,000,000 from federal estate tax.11Internal Revenue Service. Estate Tax To claim the deceased spouse’s unused exemption, the executor of the first spouse’s estate must file Form 706, even if the estate owes no tax. The standard deadline is nine months after the date of death, with an optional six-month extension.12Internal Revenue Service. Filing Estate and Gift Tax Returns A simplified late-filing method under Revenue Procedure 2022-32 allows the portability election up to five years after death; missing that window forfeits the unused exemption permanently.13Internal Revenue Service.

Deductions and Gifts That Shrink the Estate
Two deductions can eliminate a taxable estate on their own, and they work whether assets are held in trust or owned outright.
The unlimited marital deduction lets you leave any amount to a surviving spouse without triggering estate tax. The full value of property passing to the spouse comes out of the gross estate, deferring the tax until the second spouse’s death.14Office of the Law Revision Counsel. 26 USC 2056 – Bequests, Etc., to Surviving Spouse One catch: the deduction generally does not cover “terminable interests,” such as giving a spouse income from a trust for life with the remainder going to children. Specialized trusts like a qualified terminable interest property trust can preserve the deduction in those cases.
The charitable deduction works the same way with no cap. Property left to qualifying charities, religious organizations, educational institutions, or government entities comes out of the gross estate in full.15Office of the Law Revision Counsel. 26 USC 2055 – Transfers for Public, Charitable, and Religious Uses Charitable remainder trusts and charitable lead trusts are common vehicles for splitting benefits between charities and family.
Gift Tax and Trust Funding
Transferring assets into an irrevocable trust is a gift, and the gift tax rules apply. In 2026, the annual gift tax exclusion is $19,000 per recipient, so you can transfer up to that amount to each beneficiary without filing a return or using up any of your lifetime exemption.16Internal Revenue Service. Frequently Asked Questions on Gift Taxes Married couples can each use the exclusion, doubling it to $38,000 per recipient.
For a trust contribution to qualify, the beneficiary must have a present right to the property rather than only a future one. Estate planners typically address this with Crummey withdrawal powers, which give each beneficiary a limited window to take out the contributed amount.
Gifts above the annual exclusion get reported on Form 709.17Internal Revenue Service. Instructions for Form 709 Those excess amounts eat into the same $15,000,000 lifetime unified credit used for the estate tax. Use it all up in gifts and further transfers, whether during life or at death, become taxable.
Generation-Skipping Transfer Tax
Trusts that pass wealth to grandchildren or later generations face an extra layer called the generation-skipping transfer tax. It applies when assets skip a generation, such as a grandparent-funded trust that benefits grandchildren while bypassing the children. Without it, families could use trusts to avoid estate tax at each generational level indefinitely.
The GST tax rate is 40%, layered on top of any estate or gift tax that may also apply. The GST exemption for 2026 matches the estate tax exemption at $15,000,000 per individual, or $30,000,000 for a married couple.1Internal Revenue Service. What’s New — Estate and Gift Tax The exemption has to be allocated to specific transfers when the trust is funded. Failing to allocate it at the right time can leave later distributions to grandchildren exposed to the full 40% tax.
State Estate and Inheritance Taxes
Falling below the federal exemption does not end the analysis. More than a dozen states and the District of Columbia impose their own estate or inheritance taxes, often with far lower thresholds than the federal government. Some states set exemptions as low as $1,000,000, so an estate well under the $15,000,000 federal line can still owe state tax. Inheritance taxes, imposed by some states, are paid by the heirs themselves, and the rate often depends on their relationship to the decedent.
An irrevocable trust that removes assets from the federal taxable estate generally provides the same benefit at the state level, but the rules vary. Some states do not offer portability between spouses, which raises the value of trust-based planning for married couples in those states. The right structure in one state may be unnecessary or inadequate in another, so the trust question ultimately depends on where you live as much as on what type of trust you choose.
