QTIP Trust: Complete Guide for Married HNW Couples (2026)

A Qualified Terminable Interest Property (QTIP) trust lets you transfer assets to your surviving spouse with a marital deduction while controlling who inherits them after the surviving spouse's death. It is one of the most widely used estate planning tools for married couples — essential in blended families, high-net-worth estates in estate-tax states, and situations where the first spouse to die needs to balance spouse support against children's inheritance protection.

2026 context: The federal estate tax exemption is $15,000,000 per individual (OBBBA, July 2025 — permanent, no sunset).¹ Married couples with estates under $30M can often rely on portability plus a simple marital bequest. But estates above $30M, couples with blended families, residents of estate-tax states, and those with generation-skipping goals still need the QTIP trust as a core tool.

What is a QTIP trust?

A QTIP trust is an irrevocable trust funded at the first spouse's death. It qualifies for the federal estate tax marital deduction under IRC §2056(a) — meaning the assets transferred into it pass estate-tax-free at the first death — while simultaneously allowing the first spouse to die to dictate who receives the trust assets after the surviving spouse's death.

The name comes from the statutory definition: "Qualified Terminable Interest Property" under IRC §2056(b)(7).² Normally, interests that "terminate" (such as a life estate — ending at the surviving spouse's death) do not qualify for the marital deduction. Congress created the QTIP exception so that married couples could defer estate tax while still directing the ultimate distribution of assets — a feature impossible with an outright bequest.

The core trade-off: marital deduction now, estate inclusion later

QTIP is a deferral tool, not a permanent tax shelter. The marital deduction eliminates estate tax at the first spouse's death, but IRC §2044 recaptures those assets: the full fair-market value of the remaining QTIP trust is included in the surviving spouse's taxable estate at their death.³

The surviving spouse cannot give away or redirect QTIP trust principal — those assets will be taxed in their estate. What they do control is the income stream during their lifetime.

What this means in practice — a worked example

Consider Harold and Irene, a married couple with a $40M estate. Harold dies first in 2026 with $20M in his name:

Harold leaves $5M outright to Irene (marital deduction — no estate tax at his death).
Harold funds a credit shelter trust with $15M — the full federal exemption. These assets are sheltered from estate tax at both deaths.
The remaining $0M QTIP trust would be the QTIP here — if Harold had left more than $15M, the surplus would go to the QTIP.

Now change the scenario: Harold's estate is $25M at death. He has used his full $15M exemption on prior IDGT gifts. Available exemption at death: $0. He wants to leave $25M to benefit Irene but ultimately land with his children from a first marriage:

$25M → QTIP trust. Marital deduction: no estate tax at Harold's death.
Irene receives all trust income (legally required — see below).
On Irene's death, QTIP assets plus growth are included in her estate under §2044.
At Irene's death, assets are distributed to Harold's children per the trust terms — not to Irene's children or a future second spouse.

Estate tax is deferred, not eliminated. But the family gets marital deduction at Harold's death, Irene gets income support for life, and Harold's children are protected.

Requirements for QTIP treatment: the four rules

Under IRC §2056(b)(7) and Treasury Regulation §20.2056(b)-7, property qualifies as QTIP only if all four of these conditions are met:⁴

Passes from the decedent. The property (or the right to the income from it) must pass from the decedent to the trust — either by will or by trust.
Qualifying income interest for life. The surviving spouse must be entitled to all the income from the QTIP trust, payable annually or more frequently. No income may go to anyone else during the surviving spouse's lifetime.
No power of appointment to others. During the surviving spouse's lifetime, no person — including the surviving spouse — may appoint any part of the QTIP trust property to any person other than the surviving spouse. (The surviving spouse may hold a general power of appointment exercisable at death, but this is optional.)
The executor makes the QTIP election. The executor must elect QTIP treatment for the property on Form 706, Schedule M. The election is irrevocable once made.

The income requirement is strict: "All income, payable annually or more frequently" means exactly that. If the trust document grants income in the trustee's discretion, or allows income to be accumulated without distributing to the spouse, the property does not qualify as QTIP. The surviving spouse must have the right to compel distribution of trust income — this is a hard requirement, not a default that the trustee can waive.

How the QTIP election works on Form 706

The QTIP election is made by the executor on Form 706 (United States Estate Tax Return), Schedule M ("Bequests, etc., to Surviving Spouse").⁵

The election is partial or full: the executor can elect QTIP treatment for all of the eligible property, part of it, or none. This flexibility is powerful:

Full QTIP election: entire trust qualifies for marital deduction. Maximum estate-tax deferral at first death. Maximum §2044 inclusion at second death.
Partial QTIP election: only a portion of the trust is elected QTIP. The non-elected portion does not get the marital deduction — it uses the first spouse's exemption (or is taxed). This is used to "zero out" the estate at the first death: elect QTIP on exactly enough property so that the net estate tax owed is $0.
No QTIP election: if the estate elects no QTIP, the marital deduction is lost on that property. Only makes sense if the estate is entirely below the exemption and QTIP creates more complexity than value.

The election is irrevocable once Form 706 is filed. Deadline: 9 months from date of death, with an automatic 6-month extension via Form 4768 (filed before the 9-month deadline).

QTIP and the marital deduction: the §2044 trap

The trade-off is built into the statute. IRC §2044 provides that if an executor elected QTIP treatment for property under §2056(b)(7) (or §2523(f) for inter vivos trusts), the fair-market value of the remaining trust is included in the surviving spouse's gross estate at death — whether or not the surviving spouse actually receives the principal.

This matters in three important ways:

Growth inside the QTIP is taxed at second death. A $10M QTIP trust funded in 2026 that grows to $18M by the surviving spouse's death in 2038 is included at $18M — the full appreciated value, not $10M.
The surviving spouse cannot reduce the §2044 exposure by giving QTIP assets away. Unlike assets they personally own, the surviving spouse cannot gift QTIP trust principal to reduce their eventual taxable estate. (They can gift their income interest, but that is rarely done.)
Step-up in basis at second death. Because QTIP assets are included in the survivor's estate under §2044, they receive a fresh step-up in basis at the surviving spouse's death. Capital gains accumulated inside the QTIP (on investments or business interests) are eliminated at that point — a significant benefit when the QTIP holds low-basis assets.

Why QTIP is essential for blended families

This is where the QTIP trust earns its reputation. Consider a family where the first spouse to die has children from a prior marriage and wants to provide for the current spouse while ensuring the ultimate inheritance goes to those children — not to the surviving spouse's family, future spouse, or estate.

Without a QTIP trust, the options are limited:

Outright bequest: the surviving spouse owns the assets outright and can redirect them to anyone — a new spouse, new children, charities — after the first spouse dies. Harold's children from a first marriage get nothing unless the surviving spouse chooses to leave them something.
Credit shelter trust only: only shelters up to the available exemption ($15M in 2026). Assets above that threshold left outright to the surviving spouse are redirectable.

With a QTIP trust, the first spouse to die drafts the trust distribution terms — typically "income to my surviving spouse for life, remainder to my children in equal shares." The surviving spouse receives the income and has access to principal for health, education, maintenance, and support (if the HEMS standard is included), but cannot redirect the remainder beneficiaries. The children's inheritance is locked in at the moment the first spouse dies and executes the trust.

A blended-family example with numbers

Robert (age 68) has $22M and two children from his first marriage. He marries Sandra (age 55), who has three children from her prior marriage. Combined estate goal: provide well for Sandra if Robert dies first, but ensure his $22M ultimately passes to his two children.

Structure at Robert's death	Estate tax at Robert's death	Sandra's income	Who gets the remainder?
Outright bequest to Sandra	$0 (marital deduction)	All income + principal	Sandra decides — could go to her children or new spouse
$15M credit shelter trust + $7M outright	$0 (exemption + marital)	Trust income + $7M outright	$15M protected for Robert's children; $7M Sandra redirects freely
$15M credit shelter trust + $7M QTIP	$0	Both trusts income + HEMS standard	All $22M → Robert's two children (irrevocable at Robert's death)

Simplified — assumes Robert's full $15M exemption allocated to credit shelter trust. 2026 federal exemption $15M per OBBBA. §2044 includes $7M QTIP (plus growth) in Sandra's estate at her death.

QTIP vs. other marital/trust structures

Structure	Marital deduction	Control of remainder	§2044 inclusion	Best for
Outright bequest	✓ Yes	✗ None — survivor owns it	No (in survivor's estate anyway)	Simple estates, no blended-family issues
QTIP trust	✓ Yes	✓ First spouse controls remainder beneficiaries	Yes — full FMV at second death	Blended families, large estates in estate-tax states
Credit shelter trust (bypass / B trust)	✗ No — uses exemption instead	✓ First spouse controls remainder	No — permanently out of both estates	GST planning, state estate tax, appreciation shelter
SLAT	✗ No — uses lifetime exemption	✓ Grantor controls at drafting	No — out of both estates	Inter vivos gifting strategy; uses exemption during life
Marital trust (general power)	✓ Yes	✗ Survivor controls remainder via power of appointment	Yes — §2041 power of appointment inclusion	Simple marital trust when survivor-control is acceptable

The most common combination for a $25M+ estate: Fund a credit shelter trust with the deceased spouse's available exemption (up to $15M in 2026), allocate the GST exemption to it, then direct any remaining taxable estate into a QTIP trust. This zeroes out estate tax at the first death while preserving the credit shelter trust's appreciation free of future estate and GST tax. See: Portability Election & DSUE Guide for how portability compares, and Dynasty Trust Guide for multi-generational GST planning.

The reverse QTIP election — protecting GST exemption

Here is a nuance that trips up even experienced practitioners. When assets pass through a QTIP trust, under the default GST rules, the surviving spouse is treated as the transferor for GST purposes (because the assets are included in their estate under §2044). This means any GST exemption the first spouse had is not applied to the QTIP trust — the surviving spouse must use their own GST exemption when the trust distributes to grandchildren.

The reverse QTIP election under IRC §2652(a)(3) changes this.⁶ The executor makes this election on Form 706, Schedule R (or a separate election statement). The effect: the first spouse to die remains the transferor for GST purposes, and the first spouse's GST exemption can be allocated to the QTIP trust at that time — locking in the exemption before the surviving spouse's death, when the trust may have grown substantially.

Why this matters: A $10M QTIP trust funded in 2026 with $15M in GST exemption allocated via reverse QTIP election will distribute to grandchildren free of GST tax even if the trust grows to $40M by the time of distribution. If no reverse QTIP election is made, only the surviving spouse's remaining GST exemption (perhaps reduced by prior allocations) can be applied at the second death, and the allocation is based on the trust's then-current value.

Important limitation: The reverse QTIP election can only be made for the entire interest — you cannot make a partial reverse QTIP election for GST purposes while electing a partial QTIP for estate tax purposes. Coordination between the estate and GST elections is critical and requires careful drafting and tax advice. Do NOT attempt this without a specialist tax advisor and trust attorney.

QTIP and step-up in basis

Because QTIP assets are included in the surviving spouse's taxable estate under §2044, they receive a full step-up in income tax basis at the surviving spouse's death — as if the surviving spouse had owned the assets outright. This eliminates any unrealized capital gain that accumulated in the trust during the surviving spouse's lifetime.

Example: A QTIP trust holds 500,000 shares of closely-held business stock purchased at $2/share (cost basis $1M). By the surviving spouse's death, the shares are worth $18M. Because those shares are included in the survivor's §2044 estate, heirs inherit them at a $18M basis — the $17M of unrealized gain is permanently eliminated. Children can sell the stock immediately after inheritance with no capital gains tax.

This step-up benefit is a major advantage of the QTIP structure over strategies like the SLAT or credit shelter trust, where assets are removed from the estate and do not receive a step-up at the surviving spouse's death. The trade-off is that QTIP assets face estate tax at the second death; assets in a credit shelter trust do not. See: Step-Up Basis Impact Calculator to model this trade-off for your specific situation.

State estate tax and QTIP

States with their own estate tax (12 states plus DC) generally follow federal QTIP rules — the election made on the federal Form 706 also applies for state purposes in most jurisdictions. However, state QTIP elections are not automatic in every state, and there are important differences:

Massachusetts, New York, Illinois, Oregon, Washington: recognize the federal QTIP election and defer state estate tax to the surviving spouse's death. The surviving spouse's estate will then owe state estate tax on the §2044 value — in New York, at rates up to 16%, with the cliff rule applying at $7.16M (2026).
New York special note: New York has a "decoupled" state estate tax exemption of $7.16M (2026). For a married couple with a $22M estate, the QTIP/credit-shelter strategy must account for the NY exemption separately. A credit shelter trust funded at $7.16M (the NY exemption) may save more state estate tax than one funded at the full federal $15M — over-funding the federal credit shelter trust may generate NY state tax at the first death. This is a common planning trap.
States without estate tax: no state QTIP considerations apply. Florida, Texas, Nevada, and most Sun Belt states have no estate or inheritance tax.

See: State Estate Tax 2026 Guide for the full table of state exemptions and rates.

When should a QTIP trust be part of your plan?

QTIP is almost always the right call when:

Blended family: you have children from a prior marriage and want to provide for your current spouse while ensuring your children inherit your assets — not your spouse's new family.
Estate above $30M in a non-estate-tax state, or above the state exemption in an estate-tax state: QTIP defers estate tax at the first death and allows the combined couple's exemptions to shelter more.
Large estate with low-basis appreciated assets: you want to preserve the step-up in basis at the second death, which argues for QTIP (inclusion under §2044) rather than a credit shelter trust (no step-up).
First-to-die wants to protect against surviving spouse's future creditors or remarriage: QTIP trust assets, unlike an outright bequest, are held in trust and protected from the surviving spouse's creditors, spendthrift issues, or a future second spouse who might redirect assets.

QTIP alone may not be enough when:

Generation-skipping is a priority: pure QTIP defers estate tax but does not permanently remove assets from the estate. Use credit shelter trust funded with GST exemption at first death, potentially paired with a reverse QTIP election on the QTIP portion. See: Dynasty Trust.
The estate has significant appreciated assets the family wants to sell soon after death: a credit shelter trust does not step up in basis at the surviving spouse's death — if the heirs plan to sell immediately after the second death either way, the QTIP's step-up advantage is moot. Model both scenarios with your advisor.
The estate is well under the applicable exemption: if the combined estate is under $30M and there are no blended-family complications or state estate tax exposure, a simpler structure (outright marital bequest + portability) may be more cost-effective. See: Portability Election Guide.

QTIP for inter vivos (living) trusts — §2523(f)

The QTIP rules are not limited to testamentary trusts (trusts created at death). Under IRC §2523(f), a donor may transfer property into a QTIP trust during their lifetime — the same income and appointment requirements apply — and elect to claim the gift tax marital deduction on the transfer, treating it as a completed gift qualifying for the marital deduction.

Inter vivos QTIP trusts are used when a couple wants to fund a QTIP trust structure while both spouses are alive — for example, when one spouse is significantly older or in poor health, and the couple wants to pre-position assets without going through probate at death. The §2044 inclusion at the surviving spouse's death still applies to any §2523(f) QTIP trust.

Common QTIP planning mistakes

Drafting the trust to give the trustee discretion over income distributions. QTIP requires the surviving spouse to be entitled to all income. Any language giving the trustee discretion to withhold or accumulate income disqualifies the trust for QTIP treatment. The income requirement is a hard rule, not a default.
Allowing the surviving spouse to appoint trust principal to others during life. The spouse can hold a testamentary general power of appointment (exercisable in their will), but any power to direct principal to third parties during the surviving spouse's lifetime kills QTIP status.
Missing the Form 706 deadline and losing the QTIP election. The election is irrevocable and must be made on a timely-filed Form 706. Unlike the portability election (which has a 5-year rescue via Rev. Proc. 2022-32), there is no simplified late-election procedure for the QTIP election. Filing Form 706 late, or failing to elect QTIP on a timely return, permanently loses the marital deduction for that property.
Not making the reverse QTIP election when GST planning is a goal. If the QTIP trust is intended to benefit grandchildren, failing to make the §2652(a)(3) reverse QTIP election means the first spouse's GST exemption is unavailable — the surviving spouse must cover the GST exposure from their own exemption at their death (when trust values may have grown substantially).
Over-funding the QTIP in a state with a low exemption. If the surviving spouse lives in New York (where the state exemption is $7.16M), a QTIP that inflates the surviving spouse's estate well above the state exemption can generate significant state estate tax. The optimal funding structure may combine a state-exemption-sized credit shelter trust with a QTIP for the balance — and must be modeled for the specific state.
Assuming the surviving spouse cannot access principal. QTIP does not require that principal be locked up entirely. A HEMS (health, education, maintenance, support) standard for trustee distributions of principal is permissible and common. The prohibition is on the surviving spouse unilaterally appointing principal to others — a trustee with an independent standard can distribute principal to the surviving spouse for their personal needs.
