US Citizen, Israeli Spouse: The Estate-Tax Trap the $15 Million Exemption Does Not Fix

This is orientation, not legal or tax advice. It maps what exists and the questions to take to a licensed professional. It does not tell you what to do about your own estate or taxes.

The assumption that quietly breaks

You are a US citizen. You have built a life in Israel. Your spouse is Israeli and is not a US citizen. Like most married couples, you assume that when one of you dies everything passes to the other with no tax, and that the tax question only comes up later, at the second death. For couples where both spouses are US citizens, that assumption is correct. For your household, it is not.

The rule that changes everything: the marital deduction

US estate tax lets a person leave an unlimited amount to their spouse with no estate tax at the first death. It is called the unlimited marital deduction, and it is the reason most married couples never think about estate tax when the first spouse dies. Congress wrote one exception into it. Under Internal Revenue Code section 2056(d), the unlimited marital deduction does not apply when the surviving spouse is not a US citizen. The reasoning is straightforward from the government's side: a non-citizen survivor could take the assets and leave the US tax system entirely, so the deferral is switched off unless the assets are locked into a specific structure.

The $15 million exemption is not the whole answer

2026 brought a large, reassuring number. Under the One Big Beautiful Bill Act, the federal estate and gift tax exemption is $15 million per person, made permanent and indexed for inflation. If the US-taxable estate at the first death is below that figure, no federal estate tax is due, non-citizen spouse or not. The trap is for estates that cross it. For a US citizen, the estate that counts is worldwide, so a home in Israel, US and Israeli brokerage accounts, retirement savings, and Israeli real estate can add up faster than people expect once currency and years of appreciation are included. When the total crosses the exemption and the survivor is not a US citizen, the amount above the exemption is exposed to estate tax at the first death, at a top rate of 40 percent, which is precisely the tax the marital deduction was supposed to defer.

A QDOT is the mechanism that restores the deferral

The fix Congress provided is the Qualified Domestic Trust, or QDOT, under Internal Revenue Code section 2056A. Assets that pass into a properly structured QDOT qualify for the marital deduction even though the surviving spouse is not a US citizen. The survivor can receive income from the trust, and estate tax is deferred until the survivor dies or takes principal out. A QDOT carries hard requirements: at least one trustee must be a US citizen or a US corporation, and the election is generally made on the estate tax return. That means the structure has to exist and be handled correctly on a deadline, in the months after a death. It is not something to improvise while grieving.

Lifetime gifts to a non-citizen spouse are capped too

The same citizenship line runs through gift tax. Spouses who are both US citizens can give each other unlimited amounts during life with no gift tax. When the recipient spouse is not a US citizen, that unlimited transfer is replaced by an annual exclusion, set at $194,000 for 2026 under Internal Revenue Code section 2523(i). Gifts above that in a single year begin using up the giver's lifetime exemption. It is a useful planning tool, but it is a cap, not the unlimited transfer that citizen couples take for granted.

Why Israel does not soften this

Two things lull US-Israeli families into doing nothing. First, Israel does not impose an estate or inheritance tax, so on the Israeli side there is genuinely nothing to plan for. Second, people assume a treaty smooths out the rest. It does not. The 1975 US-Israel tax treaty is an income tax treaty, and by its own terms it does not cover estate, gift, or generation-skipping transfer taxes. There is no US-Israel estate tax treaty to provide relief or a credit here. The US taxes its citizen's worldwide estate, the non-citizen-spouse rule is a US rule, and nothing on the Israeli side offsets it.

What to do

If your household fits this description, a US citizen married to a non-citizen with a combined estate anywhere near the exemption, the practical steps are to have your wills and any trust structure reviewed by an attorney who works across both systems, to understand whether a QDOT belongs in your plan, and to know that the QDOT decision is time-sensitive at death. This is general information, not legal or tax advice. Cross-border estates turn on the specific assets, where they sit, and each spouse's exact status, so the right move is to have a US-Israel estate attorney review your plan before anything is signed.
