To qualify as a QTIP trust under federal tax law, the trust must meet three requirements: the surviving spouse must be entitled to all the income from the trust property for life, paid at least annually; no one may have the power to direct trust property to anyone other than the surviving spouse during the spouse’s lifetime; and the deceased spouse’s executor must formally elect QTIP treatment on the federal estate tax return. Meeting all three qualifies the property for the unlimited marital deduction and defers federal estate tax until the surviving spouse dies. Miss any one, and the trust does not qualify.
All Income to the Surviving Spouse for Life
The tax code calls this a “qualifying income interest for life,” and it is the foundation the rest of the structure sits on. The surviving spouse must receive all the net income the trust produces, and the trustee must distribute it at least once a year. No one else can be an income beneficiary during the spouse’s life.
The income right has to be mandatory. Language that lets the trustee decide whether to distribute, accumulate income for later, or split payments with someone else destroys the qualification. If the trust document is silent on how often income must be paid, local law controls, but only if local law itself requires distributions at least annually.
Non-productive assets create a specific problem. Undeveloped land, closely held business interests, and similar holdings may generate little or no current income, which conflicts with the all-income rule. The Treasury Regulations handle this by requiring that the surviving spouse have the power to compel the trustee either to make the property productive or to sell it and reinvest the proceeds in something that produces income. Some states grant this power by default under their trust laws, but relying on state law instead of writing the power into the document is a gamble careful drafters avoid.
Income that accrues between the last distribution and the spouse’s death does not have to be paid out before death for the trust to qualify. The regulations expressly allow that gap. The trust should still direct any accrued but undistributed income at death to the surviving spouse’s estate so it is properly accounted for.
No Power To Shift Property Away From the Spouse During Life
The second requirement bars any person from having the power, during the surviving spouse’s lifetime, to direct trust property to anyone other than the surviving spouse. This applies to the trustee, the surviving spouse, and any third party. A single provision permitting lifetime distributions to children, grandchildren, or anyone else disqualifies the entire trust.
The restriction runs only during the surviving spouse’s life. Powers that take effect at or after the spouse’s death are fine, and they are how the first spouse controls where the property ultimately lands. A trust that lets the trustee distribute among the grantor’s descendants once the surviving spouse dies does not violate the rule.
Principal distributions to the surviving spouse are allowed. Trustees are commonly given the power to invade principal for the spouse’s health, education, maintenance, and support. The property is going to the spouse, so the rule is not offended. The one exception: if the spouse is legally obligated to hand the distributed property to someone else, the requirement fails.
This is where good intentions cause problems. A clause permitting the trustee to pay a grandchild’s tuition, make holiday gifts, or help a family member through a hardship will kill the QTIP treatment. There is no de minimis exception and no forgiveness for family need.
The Executor’s Election on Form 706
A trust that satisfies every drafting requirement is still not a QTIP trust until the deceased spouse’s executor makes an affirmative election. The trust instrument creates the potential; the election activates it.
The election is made on IRS Form 706, the federal estate and generation-skipping transfer tax return, by listing the qualifying property on Schedule M, the schedule that handles marital deduction claims. Form 706 must be filed within nine months of the decedent’s death. An automatic six-month extension is available by filing Form 4768 before the original deadline.
Once made, the election is irrevocable. The executor cannot reverse it after the filing deadline, including extensions, has passed. That finality means the trust document should be verified against every QTIP requirement before the election is made. Electing QTIP treatment for a trust that does not actually qualify wastes the marital deduction and produces a tax bill that cannot be undone.
Partial Elections and Trust Division
The executor does not have to elect QTIP treatment for the full trust. A partial election, covering only a fractional or percentage share of the qualifying property, is expressly permitted, and executors use this flexibility routinely to fine-tune the result.
The common move is to elect QTIP treatment for just enough of the trust to bring the deceased spouse’s taxable estate down to zero after applying the available exclusion. The elected portion qualifies for the marital deduction; the rest uses the exclusion. The election has to be expressed as a fraction or percentage so the elected share tracks any change in value between the election and the eventual distribution. A formula defining the fraction is acceptable.
When a partial election is made, the trust is typically split into two separate trusts, one holding the elected QTIP portion and the other holding the non-elected portion. The split must happen before the end of the estate administration period and must be based on fair market values at the time of division. If the division has not occurred by the time Form 706 is filed, the executor must clearly signal the intent to divide on the return. The two resulting trusts then run independently.
Drafting Mistakes That Disqualify a QTIP Trust
Most QTIP failures happen in the drafting, not the election. The document has to be right before the grantor dies; fixing it after is rarely possible. A few errors show up over and over:
- Discretionary income. Language letting the trustee decide whether to distribute income, or permitting accumulation, destroys the qualifying income interest. Income has to be mandatory.
- Third-party distributions during the spouse’s life. Any provision allowing principal to go to children, grandchildren, or anyone else while the spouse is alive disqualifies the trust.
- Contingent income interests. An income right that ends on remarriage, relocation, or any event other than the spouse’s death is not a qualifying income interest for life. It has to be unconditional from the grantor’s death forward.
- Missing conversion power. If the trust holds non-productive assets and neither the document nor state law gives the spouse the right to demand conversion to income-producing property, the all-income requirement fails.
- General power of appointment. Giving the surviving spouse a broad lifetime power to appoint trust property to anyone violates the appointment restriction. Limited testamentary powers are fine.
Each of these is binary. The trust either qualifies or it does not. There is no partial credit and no substantial compliance doctrine to fall back on.
What Happens at the Second Death
The marital deduction at the first death is deferral, not elimination. When the surviving spouse dies, the full fair market value of the QTIP trust property is included in the surviving spouse’s gross estate, even though the spouse never owned the property outright and had no power to give it away. The value used is the fair market value on the date of the surviving spouse’s death, or the alternate valuation date if elected.
That inclusion sits on top of whatever the surviving spouse owned in their own name. For a surviving spouse who has accumulated significant separate wealth, the QTIP property can push the combined estate well above the applicable exclusion.
Because the QTIP property inflates the surviving spouse’s estate, the tax code gives the estate the right to recover the added estate tax from the people who actually receive the QTIP assets, typically the first spouse’s children from a prior marriage. The recoverable amount is the difference between what the estate paid and what it would have paid without the QTIP property in the mix. The surviving spouse can waive this right, but only by a specific reference in their will or revocable trust; a generic clause directing the estate to pay all taxes from the residuary is not enough. If the estate has the right and fails to exercise it, that failure is treated as a taxable gift to the remainder beneficiaries.
There is an upside to the inclusion. Because the property is in the gross estate, it receives a new income tax basis equal to its fair market value at the surviving spouse’s death. Built-in capital gain that accrued during the trust’s existence is wiped out. For remainder beneficiaries inheriting appreciated real estate or stock, the basis adjustment can save more in future capital gains tax than the estate tax cost. The basis cannot exceed the value reported on Form 706, and the two must be consistent.
The Reverse QTIP Election for GST Purposes
QTIP property is also exposed to the generation-skipping transfer (GST) tax when it eventually passes to grandchildren or more remote descendants. Because the QTIP election treats the surviving spouse as the transferor for estate tax purposes, the surviving spouse’s GST exemption would normally apply. That can waste the first spouse’s own GST exemption.
The reverse QTIP election fixes this. The deceased spouse’s executor can elect to treat the trust as if the QTIP election had never been made, but only for GST purposes. Estate tax treatment is unchanged. The first spouse remains the transferor for GST purposes and can allocate their own GST exemption to the trust. The election is made on Form 706 and is irrevocable.
The reverse QTIP election applies to the entire trust. It cannot be made for a fractional share. If the executor wants the reverse election to cover only part of the QTIP property, the trust has to be divided first, so the election can apply to one resulting trust and not the other.
