A marital trust holds the share of a deceased spouse’s estate that is set aside for the surviving spouse. Because it qualifies for the unlimited marital deduction, no estate tax is due at the first death. Unlike leaving everything outright, a marital trust lets the first spouse decide where the property goes after the survivor’s death, which is why it is so useful for second marriages and blended families.
Marital trust, in short: A marital trust receives the deceased spouse’s assets for the surviving spouse’s benefit and qualifies for the federal estate tax marital deduction, so no estate tax is owed at the first death (26 U.S.C. § 2056). The assets are included in the survivor’s estate at their death, where they receive a new income tax basis. The most common kind is a QTIP trust, which pays the survivor all of the income for life while locking in who receives the property afterward, protecting it from a remarriage.

Property passing from a deceased spouse to a surviving spouse who is a U.S. citizen generally qualifies for an unlimited estate tax deduction (26 U.S.C. § 2056). Leaving property outright qualifies, but so does leaving it in a properly drafted trust. Most plans for larger estates split the deceased spouse’s share in two:
| Type | Survivor’s rights | Who decides the final beneficiaries | Law |
|---|---|---|---|
| QTIP trust | All income for life, paid at least annually; principal as the trust allows | The first spouse | § 2056(b)(7) |
| General power of appointment trust | All income for life plus the power to leave the property to anyone | The surviving spouse | § 2056(b)(5) |
| Estate trust | Income can be accumulated; the property passes to the survivor’s estate | The surviving spouse, through their will | § 2056 |
| QDOT (non-citizen spouse) | Required for the marital deduction when the survivor is not a U.S. citizen | Depends on the trust terms | § 2056A |
For most families we use a QTIP trust.
When everything passes outright to a surviving spouse, the survivor can later leave it to a new spouse or to anyone else. A QTIP marital trust prevents that. The survivor receives all of the income and, if the trust allows, principal for their needs, but the first spouse’s chosen beneficiaries, usually their own children, receive what is left. Texas community property makes this especially important, because each spouse owns half of what the couple acquired during the marriage and can direct only their own half.

A QTIP trust is the most common kind of marital trust. Other kinds include a general power of appointment trust, an estate trust and, for a non-citizen spouse, a QDOT.
It defers it. No estate tax is due at the first death, but the marital trust is included in the surviving spouse’s estate at their death, where the survivor’s own exemption can shelter it.
Not with a QTIP trust. The first spouse decides who receives the property after the survivor’s death. With a general power of appointment trust, the survivor decides.
The unlimited marital deduction generally applies only if the property passes to a qualified domestic trust (QDOT), which has its own rules.
Larger estates often use both: a bypass trust up to the exemption and a marital trust for the rest. Smaller estates may use a single flexible trust.
