QTIP Trusts and Marital Deduction (§ 2044 / § 2056)

A Qualified Terminable Interest Property (QTIP) trust — authorized under 26 U.S.C. § 2056(b)(7) — is the workhorse of blended-family estate planning and the mechanism that allows a first-to-die spouse to both defer estate taxes through the marital deduction and control where the assets ultimately land when the surviving spouse dies. Without QTIP, a spouse wanting the marital deduction would have to leave assets outright to the surviving spouse — surrendering all control over the ultimate disposition. QTIP threads the needle: the surviving spouse receives all income for life (satisfying the marital deduction's income requirement), but the trust corpus passes at the surviving spouse's death to the first spouse's designated beneficiaries — typically children from a prior marriage. 26 U.S.C. § 2044 closes the loop by including QTIP trust assets in the surviving spouse's gross estate at their death, ensuring that the estate tax deferred at the first death is eventually collected at the second death. The QTIP / § 2044 structure is one of the clearest examples of estate tax deferral (not elimination) in the code: tax is postponed, not forgiven, and the IRS ultimately collects at the surviving spouse's estate using the QTIP assets as the tax base.

Current Law (2026)

QTIP trusts defer estate tax by qualifying for the marital deduction at the first death, with inclusion in the surviving spouse's estate at the second death.

Key Mechanics

A QTIP trust (Qualified Terminable Interest Property) is the primary estate planning tool for providing for a surviving spouse while controlling the ultimate disposition of assets. The mechanics: (1) QTIP election — the executor of the first spouse's estate makes an irrevocable election on Form 706 to treat a trust as QTIP; the trust must pay all income to the surviving spouse at least annually, and no one (including the surviving spouse) may appoint the trust property to anyone other than the surviving spouse during the spouse's lifetime; qualifying trusts receive the unlimited marital deduction under § 2056(b)(7), eliminating estate tax at the first spouse's death; (2) § 2044 recapture — at the surviving spouse's death, the full fair market value of remaining QTIP assets is included in the surviving spouse's gross estate even though the spouse never owned them outright; the trust gets a § 1014 step-up in basis at the surviving spouse's death; (3) partial election — executors may make a partial QTIP election over only a portion of the trust to optimize the use of the first spouse's estate tax exemption versus the marital deduction (Clayton QTIP planning). The QTIP is critical in blended families: assets in a QTIP trust pass to the first spouse's chosen beneficiaries (typically children from a prior relationship) at the surviving spouse's death, protected from the surviving spouse's future marriages, creditors, or transfers. At the surviving spouse's death, the QTIP trust's estate tax burden is apportioned against the trust's assets unless the trust instrument provides otherwise. Interaction with portability: the deceased spouse's unused exclusion amount (DSUEA) and a QTIP election can be used together — the executor can elect to port unused exemption AND make a QTIP election over the remaining estate.

Legal Authority

• 26 U.S.C. § 2056 — Bequests to surviving spouse (the marital deduction; § 2056(b)(7) authorizes the QTIP election)
• 26 U.S.C. § 2044 — Certain property for which marital deduction was previously allowed (the § 2044 inclusion rule at surviving spouse's death)
• 26 U.S.C. § 2056A — Qualified domestic trust (QDOT — marital deduction for non-citizen surviving spouses, a different structure)
• 26 U.S.C. § 2056(b)(5) — General power of appointment trust (alternative marital deduction trust where spouse has full power of appointment — contrasts with QTIP's limited income interest)
• 26 U.S.C. § 2010(c) — Portability of the deceased spousal unused exclusion amount (DSUEA — the surviving spouse can "inherit" unused exemption from the first spouse, which interacts with QTIP planning)
• 26 U.S.C. § 2044 (DB) — Certain property for which marital deduction was previously allowed: this section applies to any property if a deduction was allowed for the transfer to the decedent under § 2056(b)(7) (QTIP election) or § 2523(f) (inter vivos QTIP), and § 2519 (relating to dispositions of certain life estates) did not apply to the decedent's prior disposition; for chapter 11 and chapter 13 (generation-skipping transfer tax) purposes, property includible under § 2044 is treated as passing from the decedent
• 26 U.S.C. § 2056 (DB) — Bequests to surviving spouse: life-income gifts, certain annuities starting within 13 months, and qualified terminable interest property all qualify for the marital deduction when the executor makes an irrevocable election on the estate tax return; if the surviving spouse is not a U.S. citizen, no deduction applies unless the property is placed in a qualified domestic trust (QDOT) before the estate tax return is filed; the IRS has 1 year after notice to assess related tax deficiencies when a court case to fix a trust is started before the return due date

How It Works

The marital deduction baseline: § 2056 allows an unlimited deduction from the gross estate for property passing to a surviving spouse who is a U.S. citizen. An estate of any size — $500,000 or $500 million — passes to a surviving spouse with zero federal estate tax if structured correctly. The marital deduction is not an exemption; it is a deferral mechanism. The deferred estate tax is collected at the surviving spouse's death, using the combined assets remaining in the surviving spouse's estate at that point.

The terminable interest problem: The marital deduction does not apply to "terminable interests" — interests that end at the surviving spouse's death or on the occurrence of some event. A trust that pays income to the surviving spouse for life and then passes to the children is a terminable interest and normally would not qualify for the marital deduction. Congress created the QTIP exception to allow this structure to qualify.

The QTIP election mechanics: If the executor of the first spouse's estate makes a QTIP election on the estate tax return (Form 706), a trust that pays all income to the surviving spouse at least annually, where no one can appoint the property to anyone other than the surviving spouse during the spouse's lifetime, qualifies for the marital deduction. The election is irrevocable. The executor can make a partial QTIP election — electing only a portion of the trust — to optimize between using the first spouse's exemption and the marital deduction, a technique sometimes called "reverse QTIP" or "Clayton QTIP" planning.

§ 2044 — The Payback: At the surviving spouse's death, § 2044 includes the full fair market value of remaining QTIP trust assets in the surviving spouse's gross estate — even though the surviving spouse never owned those assets outright and cannot leave them to whomever they choose. The statute treats the QTIP assets as if the surviving spouse owned them, for estate tax purposes only. The surviving spouse's estate pays estate tax on the QTIP assets as part of their gross estate calculation, and the QTIP trust assets bear their proportionate share of the estate tax liability (unless the trust instrument provides otherwise). The QTIP trust also receives a § 1014 step-up in basis at the surviving spouse's death — because the assets are included in the estate, they qualify for the stepped-up basis just like any other estate asset.

Blended family use case: The QTIP trust is most important in second marriages where each spouse has children from a prior relationship. The first-to-die spouse (say, Spouse A) wants to provide for the surviving spouse (Spouse B) without risk that Spouse B will redirect the assets to Spouse B's own children or a new spouse after Spouse A's death. By placing assets in a QTIP trust, Spouse A ensures: (1) Spouse B receives income for life (appropriate support); (2) the assets are protected from Spouse B's creditors and future spousal claims; and (3) at Spouse B's death, the trust passes to Spouse A's designated beneficiaries — typically Spouse A's children. The QTIP mechanism preserves marital deduction treatment while locking in Spouse A's succession plan.

Portability and QTIP interaction: The portability election (§ 2010(c)) allows the surviving spouse to "inherit" the deceased spouse's unused federal estate tax exemption (the DSUEA). A surviving spouse who inherits the DSUEA can apply it to their own estate at death — effectively doubling the available exemption for the combined marital estate. QTIP trusts interact with portability: the assets in the QTIP trust are included in the surviving spouse's estate under § 2044 and are potentially protected by the DSUEA. Estate planners must decide whether to use a QTIP trust (deferring estate tax), a credit-shelter trust (using the first spouse's exemption immediately), or portability (preserving the unused exemption) — or a combination. The optimal structure depends on the relative size of the estates, state estate tax, and projected asset appreciation.

Credit-shelter trust vs. QTIP: A credit-shelter trust (also called a bypass trust) uses the first spouse's exemption immediately — assets up to the exemption amount go into the bypass trust, which is not in either spouse's estate. Assets above the exemption go into the QTIP trust, claiming the marital deduction. This "A-B trust" structure was the standard before portability was enacted in 2011. With portability available, some estate planners use a simpler structure (all assets to QTIP, plus portability election) — but the A-B structure still provides state estate tax benefits (many states don't recognize portability) and protection from asset appreciation (assets in a bypass trust don't grow in the surviving spouse's estate).

How It Affects You

If you are in a second marriage with children from a prior relationship: QTIP trust planning is designed for your situation. Without it, you face a genuine conflict: leaving assets outright to your surviving spouse means those assets could ultimately pass to your spouse's children (from their prior marriage or a subsequent one), to a new spouse, or simply be consumed. Leaving assets to your children directly means your surviving spouse has no support. A QTIP trust provides both: your spouse is supported for life through income distributions, and at your spouse's death, the trust passes to your children. The QTIP election on your estate tax return preserves the marital deduction — meaning no estate tax at your death — while ensuring your succession intent is honored. You should also address the credit-shelter trust question: should some assets bypass the QTIP and go directly into a trust that uses your exemption, avoiding inclusion in your spouse's estate at all?

If you're the surviving spouse and beneficiary of a QTIP trust: You should understand what § 2044 means for your estate planning. The QTIP assets you receive income from during your lifetime will be included in your taxable estate at your death at their full fair market value — even though you cannot leave those assets to anyone of your choosing. Your estate tax exposure therefore includes assets you don't fully control. Your estate plan should account for the QTIP assets' projected value at your death in calculating potential estate tax liability. You can potentially use your DSUEA (inherited exemption) from your deceased spouse to offset the QTIP inclusion — but only if the portability election was timely filed by your late spouse's executor. If portability was not elected, that exemption is permanently lost.

If you're an estate planning attorney or financial advisor modeling marital deduction options: The core tension in QTIP planning is the deferral trade-off: QTIP defers estate tax to the second death, potentially at a higher effective rate (if the combined estate grows), while using the first spouse's exemption immediately via a credit-shelter trust removes assets from the estate entirely. The optimal split between QTIP and credit-shelter depends on: (1) whether the state has an estate tax and recognizes portability; (2) the projected growth of assets (faster-growing assets are better in the credit-shelter trust); (3) the surviving spouse's longevity; and (4) the relative sizes of the two spouses' exemptions. With elevated federal exemptions ($15M per person, made permanent by OBBBA Pub. L. 119-21), more clients can use portability alone — but for states with low exemptions (OR, MA) and for wealthy families, active QTIP/credit-shelter optimization remains essential.

State Variations

QTIP trusts are relevant in all states with estate taxes, and their state-level treatment adds important complexity. Most states with estate taxes recognize the QTIP election for state estate tax purposes (following federal § 2056(b)(7) mechanics), but several do not recognize portability — meaning the surviving spouse cannot use the deceased spouse's unused state exemption regardless of a portability election. In these states (including MA, OR, WA, MN, and others), the credit-shelter trust remains essential for capturing the first spouse's state exemption. In New York, a QTIP trust qualifies for the New York estate tax marital deduction, but New York's "estate tax cliff" (where the gross estate exceeding 105% of the NY exemption results in no exemption at all) requires careful optimization. Multi-state couples should identify the estate tax laws of all states where they own real property, since real property is taxed in the state where it's located — not the state of domicile.

Implementing Regulations

• 26 CFR § 20.2056(b)-7 — Election with respect to life estate for surviving spouse (the QTIP regulations: what constitutes qualified income interest for life; the "all income" requirement; the no-appointment restriction; partial QTIP elections; joint and mutual will issues)
• 26 CFR § 20.2056(b)-5 — Life estate with power of appointment in surviving spouse (the general power of appointment trust alternative to QTIP — not subject to § 2044 because the surviving spouse has a full general power)
• 26 CFR § 20.2044-1 — Certain property for which marital deduction was previously allowed (the § 2044 inclusion regulations; determining which property is QTIP; the surviving spouse's estate's right of recovery from the trust for estate taxes attributable to QTIP inclusion)
• 26 CFR § 20.2010-3 — Portability provisions applicable to the surviving spouse's estate (DSUEA election, computation, and interaction with QTIP election)

Pending Legislation

• Portability permanence: The portability election was made permanent by ATRA 2012 but remains subject to legislative change. Proposals to limit portability (requiring it to be used or lost within a shorter window, for example) would increase the importance of QTIP credit-shelter trust planning as the primary tool for two-exemption optimization.
• State estate tax reform: Several states with high estate tax burdens (Massachusetts, Oregon) are under political pressure to raise exemptions or eliminate their state estate tax entirely. Changes in state estate tax law directly affect the value of QTIP planning structures designed to optimize state estate tax — plans written today may need updating if state exemption levels change.
• S. 587 / H.R. 1301 (Sen. Thune [R-SD] / Rep. Feenstra [R-IA-4]) — Death Tax Repeal Act of 2025: would repeal the federal estate and GST taxes; if enacted, the QTIP election and § 2044 inclusion would be eliminated, fundamentally changing marital estate planning — though QTIP structures would still serve asset protection and state estate tax purposes. Status: introduced.
• S.J.Res. 72 (Sen. Whitehouse [D-RI]) — Would nullify the IRS rule updating estate tax closing letter user fees; affects administration of estates relying on closing letters to confirm finality of § 2044 QTIP inclusion and estate tax computation at the surviving spouse's death. Status: introduced.
• H.R. 601 (Rep. Arrington [R-TX-19]) — Estate Tax Rate Reduction Act: would set a uniform 20% flat rate on estates, gifts, and GST transfers; would reduce the marginal cost of § 2044 QTIP inclusion at the surviving spouse's death while keeping the two-spouse deferral structure intact. Status: introduced.

Recent Developments

• Clayton QTIP planning: A "Clayton QTIP" provision — where the executor's decision not to make a QTIP election causes assets to pass to a credit-shelter trust rather than the QTIP trust — allows post-death optimization of the QTIP/credit-shelter allocation. This flexibility is valuable because the optimal allocation often depends on facts known only after death (exact asset values, applicable tax law, state of domicile). Tax courts have generally upheld Clayton QTIP provisions, and they are increasingly standard in well-drafted marital deduction trusts.
• QTIP and the step-up at second death: QTIP trust assets receive a full § 1014 step-up in basis at the surviving spouse's death because they are included in the surviving spouse's estate under § 2044. This is a significant benefit that is sometimes underappreciated: highly appreciated assets inside a QTIP trust that have grown since the first spouse's death receive a clean stepped-up basis at the second death, eliminating all embedded capital gains for the remainder beneficiaries. The step-up at the second death applies to all QTIP assets, regardless of who the ultimate beneficiaries are — including the first spouse's children from a prior marriage.
• Surviving spouse remarriage and QTIP interaction: If the surviving spouse remarries, the income interest from the QTIP trust continues — the QTIP trust cannot be diverted to a new spouse. However, the surviving spouse's own assets (outside the QTIP trust) can be left to a new spouse through a new marital deduction. The QTIP structure insulates the first spouse's assets from the surviving spouse's second marriage, which is precisely what it is designed to do. Estate planners increasingly encounter multi-generation QTIP planning questions as second marriages become more common in wealthy families.
