The difference between a marital trust and a QTIP trust is really a difference within the marital trust category: a QTIP trust is one kind of marital trust, and the thing that sets it apart from the other common kind is control over where the assets go after the surviving spouse dies. A QTIP trust locks in the remainder beneficiaries chosen by the grantor. The other main form, a General Power of Appointment trust, lets the surviving spouse redirect those assets to anyone they want. Both qualify for the unlimited marital deduction, so no federal estate tax is owed when assets move into either trust at the first spouse’s death.
What a Marital Trust Is
A marital trust is any trust designed to hold assets for a surviving spouse while taking advantage of the federal estate tax marital deduction. Federal law lets you transfer an unlimited amount of property to your spouse without triggering estate tax, during life or at death.1Office of the Law Revision Counsel. 26 USC 2056 – Bequests, Etc., to Surviving Spouse The tax isn’t erased. It’s deferred until the surviving spouse dies and their own estate is taxed.
Two structures do the job. One is a General Power of Appointment trust, under Section 2056(b)(5) of the tax code. The other is a QTIP trust, under Section 2056(b)(7). Both require that the surviving spouse receive all income from the trust, paid at least once a year. What divides them is what the surviving spouse can do with the underlying principal.
How a General Power of Appointment Trust Works
In this version, the surviving spouse gets wide authority. They receive all income for life, and they also hold the power to direct where the trust assets go when they die. They can name anyone as the final beneficiary, including a new spouse, a charity, or someone the original grantor never intended to benefit.1Office of the Law Revision Counsel. 26 USC 2056 – Bequests, Etc., to Surviving Spouse The statute requires that this power be exercisable by the surviving spouse alone and “in all events,” so no one else can override or restrict their choice.
This fits couples in a first marriage with shared children, where both spouses agree on who should ultimately inherit and want the survivor to have room to adapt. If a child develops a disability, if a grandchild needs education funding, if the family’s circumstances shift, the surviving spouse can respond.
How a QTIP Trust Works
A Qualified Terminable Interest Property trust flips the control. The surviving spouse still receives all income from the trust for life, paid at least annually, but they have no say in who ultimately receives the principal.1Office of the Law Revision Counsel. 26 USC 2056 – Bequests, Etc., to Surviving Spouse The grantor names the remainder beneficiaries in the trust document, and those designations cannot be changed after the grantor dies. No one, including the surviving spouse, can redirect the trust assets to anyone else during the spouse’s lifetime.
The QTIP trust exists because of a tension in the tax code. The general rule denies the marital deduction for “terminable interests,” meaning interests that end at some point and then pass to someone other than the surviving spouse. A QTIP trust is technically a terminable interest: the surviving spouse’s right to income ends at death, and the remaining assets go to the grantor’s chosen beneficiaries. Congress created Section 2056(b)(7) as a specific exception, allowing the marital deduction for this arrangement as long as certain requirements are met and the executor makes a formal election on the estate tax return.2Internal Revenue Service. Instructions for Form 706 (09/2025) – Section: Schedule M—Bequests, etc., to Surviving Spouse (Marital Deduction)
Principal Distributions Are Still Possible
A common misconception is that a QTIP trust can never distribute principal to the surviving spouse. That’s wrong. The Treasury regulations state that a qualifying income interest for life is not disqualified just because the trustee has the power to distribute principal to the surviving spouse.3eCFR. 26 CFR 20.2056(b)-7 – Election With Respect to Life Estate for Surviving Spouse Many QTIP trusts let the trustee invade principal for the spouse’s health, education, maintenance, or support. What the trust cannot do is give anyone the power to distribute principal to someone other than the surviving spouse while the spouse is alive.
The Core Difference: Who Controls the Remainder
In a General Power of Appointment trust, the surviving spouse effectively becomes the owner of the trust assets for planning purposes. They can rewrite the ending. In a QTIP trust, the grantor writes the ending and it stays written.
That difference matters in predictable situations. A surviving spouse who remarries might feel pressure from a new partner to redirect assets. A surviving spouse in financial difficulty might benefit creditors over the grantor’s intended heirs. A surviving spouse with a strained relationship with a stepchild might cut them out entirely. A QTIP trust prevents all of these outcomes by stripping the surviving spouse of any appointment power over the principal.
The tradeoff is rigidity. If circumstances change in ways the grantor didn’t anticipate, the trust terms generally stand. Courts can modify irrevocable trusts in some situations, but the bar is high and the process is expensive. Anyone choosing a QTIP trust should think carefully about whether their remainder beneficiary designations will still make sense decades later.
When Each One Fits
The QTIP trust is the standard tool for blended families. A grantor with children from a prior marriage faces a real conflict: they want to provide for their current spouse, but they also want to make sure their children eventually inherit. Without a QTIP trust, those two goals can collide.4Kiplinger. This Is How the ‘Brady Bunch’ Safety Net (aka a QTIP Trust) Protects Your Kids’ Inheritance
The QTIP structure splits the benefit cleanly. The surviving spouse receives all trust income for life. The children from the prior marriage are named as remainder beneficiaries, so they receive the principal after the surviving spouse dies. The surviving spouse cannot change this, even if they remarry or draft a new estate plan that would otherwise exclude the grantor’s children. The irrevocability also protects the principal from the surviving spouse’s personal creditors if they later face a lawsuit, bankruptcy, or significant debts.
A General Power of Appointment trust tends to fit a different situation: one marriage, shared children, aligned goals, and a desire to give the survivor flexibility to respond to life after the first death.
The QTIP Election and Partial Election
Setting up a QTIP trust in your estate plan doesn’t automatically trigger the marital deduction. The executor of your estate must affirmatively make a “QTIP election” on Schedule M of IRS Form 706, the federal estate tax return. The election is made by listing the qualified terminable interest property and entering its value on the return.2Internal Revenue Service. Instructions for Form 706 (09/2025) – Section: Schedule M—Bequests, etc., to Surviving Spouse (Marital Deduction) If the executor fails to make this election on a timely filed return, the trust won’t qualify for the marital deduction, and the assets could be subject to immediate estate tax.
One useful feature is that the choice isn’t all-or-nothing. The executor can elect QTIP treatment for all, some, or none of the trust assets. A partial election means part of the trust qualifies for the marital deduction and part does not, giving the executor room to calibrate the estate tax result once actual asset values are known. A trust can be designed with that strategy in mind from the start.
What Happens at the Surviving Spouse’s Death
The marital deduction defers estate tax; it doesn’t eliminate it. When the surviving spouse dies, the full value of the QTIP trust is included in their gross estate, even though they never controlled the principal and couldn’t direct where it went.5eCFR. 26 CFR 20.2044-1 – Certain Property for Which Marital Deduction Was Previously Allowed The amount included is the fair market value of the trust assets at the surviving spouse’s date of death, not the value when the trust was funded.
If the first executor made a partial QTIP election, only the corresponding fraction of the trust’s value at the second death is pulled in. If the first executor elected QTIP treatment for 60% of the trust, then 60% of the trust’s value at the surviving spouse’s death is included in that spouse’s estate.5eCFR. 26 CFR 20.2044-1 – Certain Property for Which Marital Deduction Was Previously Allowed
Because QTIP trust assets are included in the surviving spouse’s gross estate, they receive a stepped-up cost basis at that death. For the remainder beneficiaries, that’s a meaningful income tax benefit. If the trust holds appreciated stock or real estate, the beneficiaries inherit those assets with a basis equal to the fair market value at the surviving spouse’s death, wiping out unrealized capital gains that accumulated during the trust’s existence. This only applies if the QTIP election was actually made on a timely filed estate tax return for the first spouse’s estate.
Costs and When the Structure Isn’t Worth It
Both marital trusts require professional drafting. Attorney fees for a complex trust-based estate plan typically range from roughly $2,000 to $5,000 or more, depending on the family situation and the assets involved. Ongoing administration adds cost. If a professional trust company serves as trustee, annual management fees generally run between 0.75% and 2.0% of the trust’s asset value, though an individual trustee such as a family member may serve for less or nothing.
A QTIP trust also creates obligations an outright bequest does not. Someone has to serve as trustee, manage investments, distribute income on schedule, file annual trust tax returns, and eventually distribute the remaining assets to the remainder beneficiaries. For smaller estates well below the federal exemption, the cost and complexity may not be justified unless the grantor’s main concern is controlling where the assets end up rather than minimizing taxes.
