The Marital Deduction You Do Not Have

Property passing to a surviving spouse ordinarily qualifies for an unlimited marital deduction, so no estate tax arises at the first death however large the estate. Section 2056(d) of the Internal Revenue Code withdraws that where the surviving spouse is not a United States citizen at the time of the decedent's death. Read the trigger carefully, because almost everyone reads it wrongly: the test is the SURVIVING spouse's citizenship. It is not about whether the person who died was a citizen, not about the survivor's residence, and not about how long either of them had been in the country. A US citizen dying with a permanent-resident spouse is inside this rule, and so is a couple where both hold green cards. The ordinary American estate plan — everything to the spouse, tax deferred until the second death — quietly does not work, and nothing in the drafting of such a plan says so.

The rationale given for the restriction is that a surviving spouse who is not a citizen could leave the country with the inherited assets, which would then escape United States estate taxation altogether rather than being taxed at the second death as the ordinary deferral assumes. That is worth knowing because it predicts everything about the remedy: any mechanism that restores the deduction has to keep the assets within reach of the tax system, which is why the remedy defers the tax rather than removing it, and why it comes with conditions about who controls the assets. A family that understands the purpose stops being surprised by the conditions.

A qualified domestic trust, under section 2056A, is the mechanism that lets property passing to a non-citizen surviving spouse qualify for the marital deduction. What it does is postpone: no estate tax falls due on the trust property at the first death, and the assets held in it become subject to estate tax when the surviving spouse dies, with certain distributions during their lifetime also capable of triggering it. This is a deferral, not an exemption, and the difference matters for anyone planning around it — a plan whose arithmetic assumes the tax has been avoided rather than postponed is wrong by the whole amount. The surviving spouse's access to capital during their lifetime is also not the unconstrained access an outright inheritance would have given, which is a consequence families should understand before it is the only option left.

Sources describing the requirements consistently name three: the surviving spouse must be entitled to all income of the trust; at least one trustee must be a United States citizen or a United States corporation; and the trust must be ELECTED by the executor of the estate on the estate tax return. The third is the one that turns a structural question into a deadline. A trust that was drafted, funded and named correctly still does not deliver the deduction unless the election is made on a return that somebody has to file, in a period when the family is dealing with a death rather than with tax administration. If there is one question to put to whoever is handling the estate, it is whether that election is on their list and when the return is due.

Section 2056(d)(4) provides that where the surviving spouse becomes a United States citizen before the day the estate tax return is filed, the property need not pass into a qualified domestic trust, nor an existing trust be reformed into one, in order to qualify for the marital deduction — with sources also describing a requirement that the survivor remain a US resident from the death until citizenship. The important structural point is what the deadline is keyed to. It is not the date of death, which cannot be planned around once it has happened; it is the filing of the return, which sits some months later. So a surviving spouse who was already close to naturalising may be inside a window in which finishing that process changes the tax treatment of the whole estate. This is the single most actionable thing on this page, it is time-limited, and it is exactly the kind of interaction that goes unnoticed because the immigration process and the estate administration are being handled by different people who are not talking to each other.

Regulations described in the sources allow an estate, in some circumstances, to choose between the statutory route and a marital deduction, exemption or credit allowed under an applicable estate tax treaty. That alternative is nationality-specific and depends on a treaty existing. For the corridor this site serves it does not: this site's own rulebook on the non-resident estate tax position establishes that there is no United States–India estate tax treaty, and that the relief other nationalities obtain through one is therefore unavailable. So for most readers here the treaty alternative is not a route to investigate but a door to know is shut — which is worth stating explicitly, because generic guidance on this subject frequently mentions the treaty option without noting that it turns entirely on which treaty, if any, applies to you.

Nothing here is estate planning advice, no structure is recommended, and no threshold, exemption figure or rate appears anywhere on this page. Two reasons. Amounts in this area are indexed and legislated and would be stale on a static page, and this surface renders no currency by design. More importantly, what is useful about this subject to somebody reading it in advance is not a number: it is knowing that the deduction their plan assumes may not exist, that the remedy postpones rather than removes, that an election has to be made on a return, and that a naturalisation already under way may interact with all of it on a deadline nobody has flagged. Take those four things to an estate lawyer who works across borders. The value of this page is in the questions it lets you ask, and the time you have to ask them.
