A qualified terminable interest property (QTIP) trust is built in two stages around four roles: the grantor sets the terms, a trustee manages the assets, the surviving spouse receives all trust income for life, and remainder beneficiaries chosen by the grantor take whatever principal is left when the surviving spouse dies. To qualify for the federal estate tax marital deduction, the trust document must meet every requirement in IRC Section 2056(b)(7), and the executor of the deceased spouse’s estate must elect QTIP treatment on Form 706. Miss any structural requirement, or skip the election, and the deduction is gone.
QTIP planning is most relevant for couples whose combined wealth approaches or exceeds the federal exemption, which is $15 million per person for 2026.1Internal Revenue Service. What’s New – Estate and Gift Tax It is especially common in blended families, where the grantor wants to provide for a surviving spouse but keep control over who ultimately inherits, usually children from a prior relationship.
The Four Parties and the Two Stages
Four roles define how a QTIP trust operates. The grantor is the deceased spouse who creates the trust and dictates its terms, including who the final beneficiaries are and what rules govern distributions. The trustee holds legal title to the trust assets and manages them according to the trust document. The income beneficiary is always the surviving spouse, who receives all trust income for life but has no power to redirect the principal. The remainder beneficiaries are the people the grantor chose to receive the trust principal after the surviving spouse dies. In blended family situations, these are typically the grantor’s children from a prior relationship.
The trust operates in two stages. In the first, the trustee invests the trust principal and distributes all income to the surviving spouse at least annually. The surviving spouse benefits from the assets but cannot give away, redirect, or bequeath the principal. When the surviving spouse dies, the second stage activates: the income interest ends, and the remaining principal passes to the remainder beneficiaries the grantor selected.
This two-stage design is what separates a QTIP from an outright bequest or a general power of appointment trust, where the surviving spouse controls everything and could leave it all to a new partner. It is also what makes the tax treatment work. Because the surviving spouse has a qualifying income interest for life, the property counts as passing to the spouse for marital deduction purposes, and estate tax is deferred until the second death. When the surviving spouse dies, the full fair market value of the QTIP property is pulled into that spouse’s gross estate under IRC Section 2044, even though the spouse never controlled the principal.2Office of the Law Revision Counsel. 26 USC 2044 – Certain Property for Which Marital Deduction Was Previously Allowed The assets also get a fresh step-up in basis at that second death under IRC Section 1014, so the remainder beneficiaries take the property at its date-of-death value.3Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent
What the Trust Document Must Contain to Qualify
A trust doesn’t become a QTIP by being called one. Section 2056(b)(7) sets structural rules that have to be baked into the document from the start. Missing even one disqualifies the trust from the marital deduction, which means estate tax hits at the first death instead of being deferred.
All Income to the Surviving Spouse, at Least Annually
The surviving spouse must be entitled to receive all income the trust generates, paid out at least once a year.4Office of the Law Revision Counsel. 26 USC 2056 – Bequests, etc., to Surviving Spouse The right has to be unconditional. The trust document cannot impose conditions like good behavior, remaining unmarried, or reaching a certain age before income payments begin. “Income” here means trust accounting income, which covers dividends, interest, rents, and similar items, but not capital gains from selling assets.
The surviving spouse must also have the right to demand that the trustee convert any non-income-producing assets into investments that generate income. If the trust holds raw land or growth stocks that pay no dividends, the spouse can require the trustee to sell those assets and reinvest in something productive. Without this right, a trustee could effectively starve the spouse of income while sitting on valuable assets, which would defeat the purpose of the income requirement.
No Power to Appoint Principal to Anyone Else
During the surviving spouse’s lifetime, no one can have the power to direct any portion of the trust principal to anyone other than the surviving spouse.4Office of the Law Revision Counsel. 26 USC 2056 – Bequests, etc., to Surviving Spouse The surviving spouse cannot appoint principal to their own children, a new partner, or anyone else. The trustee cannot distribute principal to the remainder beneficiaries while the spouse is alive, either. Limited exceptions let the trustee invade principal for the surviving spouse’s benefit under an ascertainable standard (health, education, maintenance, and support), but any discretion to distribute principal to a third party before the spouse’s death kills the QTIP qualification entirely.
Property Must Pass From the Decedent
The assets funding the trust must pass from the deceased spouse, meaning the transfer results from the decedent’s death. Property the surviving spouse already owned, or assets that reached the trust through some other mechanism unrelated to the death, generally cannot be elected as QTIP property.
The Executor’s Election
Even a perfectly drafted trust does not receive QTIP treatment automatically. The executor of the deceased spouse’s estate must affirmatively elect it on the federal estate tax return, and that election is a statutory condition, not a default.4Office of the Law Revision Counsel. 26 USC 2056 – Bequests, etc., to Surviving Spouse
The election is made on IRS Form 706, the federal estate tax return, by completing Schedule M and designating specific property as qualified terminable interest property. It has to be made on the last return filed before the due date, including extensions, and once made, it is irrevocable. The election tells the IRS two things at once: the estate is claiming the marital deduction now, and the surviving spouse’s estate will pick the property up later under Section 2044.
The executor does not have to elect QTIP treatment for the entire trust. A partial election, expressed as a fraction or percentage, lets the executor pass only enough into the marital deduction to zero out the current estate tax, while leaving the remainder to absorb the deceased spouse’s available exemption. For 2026, that exemption is $15 million per person.1Internal Revenue Service. What’s New – Estate and Gift Tax Splitting the election is one of the more consequential decisions in the process, because it determines how the tax burden is distributed between the two estates.
Protective Elections
When the value of certain assets is genuinely uncertain, such as a closely held business interest being contested or real estate subject to appraisal disputes, the executor can file a protective QTIP election. The protective election activates only if the assets turn out to be includible in the gross estate or if their final value exceeds initial estimates, and it must identify the specific asset or trust it covers.5Internal Revenue Service. Revenue Procedure 2016-49 If the contingency never materializes, the election has no effect.
When an Unnecessary Election Is Treated as Void
An executor who makes a QTIP election that was not needed to reduce estate tax, and who did not elect portability, may find the IRS treats the election as void under Revenue Procedure 2016-49. The reasoning is that an unnecessary election inflates the surviving spouse’s taxable estate with no offsetting benefit. The IRS will not void the election, however, if it was a protective election, if the executor elected portability on the same return, or if the election was expressed as a formula designed to reduce tax to zero.5Internal Revenue Service. Revenue Procedure 2016-49
Structural Variants That Still Qualify
The base QTIP structure supports several variants that keep marital deduction qualification while solving different planning problems. Each changes how the trust is built or when the election is made, so they belong to the structure question, not the sidelines.
Clayton Provisions
Some trust documents include a Clayton provision, named after the Tax Court case that validated it. The trust terms are contingent on the executor’s election: property the executor elects as QTIP flows into a marital trust for the surviving spouse, while property the executor does not elect passes immediately to other beneficiaries, typically the grantor’s children. The IRS confirmed through final regulations that an income interest contingent on the executor’s QTIP election still qualifies as a lifetime income interest, so the arrangement does not disqualify the trust.6Internal Revenue Service. Estate and Gift Tax Marital Deduction Amendments Conforming to Clayton v. Commissioner Clayton provisions give the executor real post-death flexibility, because the split between the marital share and the family share is set with asset values and exemption amounts known at that time.
Reverse QTIP Election for GST Planning
A standard QTIP election makes the surviving spouse the transferor of the trust property for both estate and generation-skipping transfer (GST) tax purposes. That means only the surviving spouse’s GST exemption can shelter the trust, and the first spouse’s GST exemption goes unused.
The reverse QTIP election, authorized by IRC Section 2652(a)(3), overrides the transferor designation for GST purposes only.7eCFR. 26 CFR 26.2652-2 – Special Election for Qualified Terminable Interest Property It tells the IRS to treat the deceased spouse as the transferor of the QTIP trust for GST tax purposes, even though the surviving spouse remains the transferor for estate tax purposes. This lets the deceased spouse’s executor allocate the deceased spouse’s GST exemption to the trust, potentially giving it a zero inclusion ratio and making distributions to grandchildren or later generations entirely GST-tax-free. In multi-generational plans, skipping the reverse QTIP election is an expensive oversight.
Lifetime (Inter Vivos) QTIPs
Most QTIP trusts are testamentary and take effect at the grantor’s death, but a QTIP trust can also be created during the grantor’s lifetime. The gift tax marital deduction under IRC Section 2523(f) mirrors the estate tax rules: if the trust gives the donee spouse a qualifying income interest for life and the donor makes an irrevocable election on the gift tax return, the transfer qualifies for the unlimited marital deduction and triggers no gift tax.8Office of the Law Revision Counsel. 26 USC 2523 – Gift to Spouse
The most common reason to build one is estate equalization. If one spouse holds most of the couple’s wealth, the other spouse’s estate tax exemption goes largely wasted at death. Transferring assets into a lifetime QTIP for the less-wealthy spouse shelters those assets with the marital deduction today, and when the less-wealthy spouse dies first, the trust property is included in their estate, consuming their exemption. Remaining trust assets then pass to the beneficiaries the wealthier spouse chose. A lifetime QTIP also provides immediate creditor protection benefits, because once assets are transferred to the irrevocable trust, they are generally beyond the reach of the grantor’s future creditors. The election on the gift tax return does not need to be made until the return’s due date, extensions included, which can reach October 15 of the following year.8Office of the Law Revision Counsel. 26 USC 2523 – Gift to Spouse
Non-Citizen Surviving Spouse: The QDOT Overlay
The unlimited marital deduction does not apply when the surviving spouse is not a U.S. citizen. To preserve the deduction in that situation, the trust must be structured as a Qualified Domestic Trust (QDOT), which layers additional requirements on top of the standard QTIP rules.
A QDOT must satisfy three structural conditions. At least one trustee must be a U.S. citizen or a domestic corporation. The trust must provide that no principal distribution can be made unless a U.S. trustee has the right to withhold the estate tax the distribution triggers. And the trust must meet additional regulatory requirements the IRS prescribes to ensure tax collection.9Office of the Law Revision Counsel. 26 USC 2056A – Qualified Domestic Trust
The tax treatment is also harsher. In a regular QTIP, estate tax is deferred until the surviving spouse dies. In a QDOT, estate tax is imposed on every principal distribution during the surviving spouse’s lifetime, calculated as if the distributed amount had been included in the deceased spouse’s taxable estate.9Office of the Law Revision Counsel. 26 USC 2056A – Qualified Domestic Trust Income distributions are exempt from this additional estate tax; they are taxed as ordinary income to the spouse, as in a regular QTIP. When the surviving spouse eventually dies, estate tax is imposed on whatever principal remains. If the trust ever ceases to meet the QDOT requirements, the entire remaining principal is treated as though the surviving spouse died on the date the trust fell out of compliance. Families with a non-citizen spouse need to build the QDOT requirements into the trust from the outset; retrofitting after the first death is far more difficult, and sometimes impossible.
What the Structure Costs to Build
Establishing a QTIP trust is not a do-it-yourself project. The trust document has to satisfy precise statutory requirements, coordinate with the rest of the estate plan (including the surviving spouse’s will and any existing trusts), and address issues like tax apportionment, trustee succession, and investment standards. Legal fees for drafting a QTIP trust typically run $5,000 to $10,000 or more, depending on the complexity of the estate and whether real estate transfers, business interests, or non-citizen spouse issues are involved. If real property is being transferred into the trust, local recording fees generally run $10 to $100 per document.
Ongoing administration adds costs as well. The trustee must file annual trust income tax returns, manage investments, make the required income distributions, and eventually coordinate with the executor of the surviving spouse’s estate on the Section 2044 inclusion. Both the upfront drafting cost and the long-term administration expense belong in the budget when a family is deciding whether a QTIP trust fits the situation.
