QDOT for NRIs: When it helps and when it does not

Many NRI couples assume that when one spouse dies, the survivor simply inherits everything tax free, the way any married couple in the US does. That is not true if the surviving spouse is not a US citizen.

The unlimited marital deduction only applies to a citizen spouse, and a green card or years of US residency do not count.

A qualified domestic trust, or QDOT, is usually the tool that keeps a large estate tax bill from landing on a non-citizen spouse the moment the first spouse dies.

Does this actually apply to you?

Check three things before reading further.

• Is your spouse a US citizen? If yes, stop here, the marital deduction already covers you and none of this applies.
• Is either of you domiciled in the US or a US citizen? If neither of you has ever been domiciled here, a different rule applies, built around a $60,000 threshold instead of $15,000,000, and a QDOT is not the fix.
• Could your combined estate, worldwide if domiciled, US assets only if not, clear $15,000,000? Below that, the exclusion already protects you and a QDOT is not necessary.

If your spouse is not a citizen, at least one of you is a citizen or domiciled in the US, and your estate could clear $15,000,000, the rest of this article applies directly to you.

Why a non-citizen spouse cannot inherit tax free

When a US citizen dies and leaves assets to a citizen spouse, the estate claims the marital deduction and pays no estate tax on that portion, no matter the amount. Congress removed that automatic benefit for non-citizen spouses in 1988, under Section 2056(d) of the tax code. Lawmakers were worried that a non-citizen spouse could take an inheritance, leave the country, and put the assets beyond the IRS's reach with no way to collect tax later.

Every estate still gets its own exclusion regardless of the spouse's citizenship: $15,000,000 for deaths in 2026. Anything left to the spouse under that amount passes without estate tax either way. The marital deduction problem only shows up above that number, where tax is due right away on the excess, at rates up to 40%, even though the same estate would owe nothing if the spouse were a citizen.

This sits inside the bigger picture of a full NRI estate plan, where the citizenship of each spouse is one of the first things worth checking.

What a QDOT is and how it works

A qualified domestic trust is a trust set up under Section 2056A that restores the marital deduction for a non-citizen spouse. Instead of assets passing directly to the surviving spouse, they pass into the trust. The estate then claims the marital deduction as if the spouse were a citizen, and the tax bill that would otherwise be due immediately gets pushed down the road.

Income from the trust, things like interest or dividends, can go to the surviving spouse without triggering estate tax. Withdrawing principal is different. Take money out of the trust for anything other than a genuine hardship, and the trustee has to withhold tax on that withdrawal right then. When the surviving spouse eventually dies, whatever remains in the trust gets taxed as part of the first spouse's estate at that point.

A QDOT does not make the tax disappear. It buys time, and it keeps the surviving spouse from facing a large, immediate bill while grieving and adjusting to life without their partner.

QDOT requirements

Setting up a QDOT trust correctly matters, because a defective one loses the deduction entirely and the estate owes tax right away.

Trustee rule

At least one trustee has to be a US citizen or a domestic corporation, usually a bank or trust company. This gives the IRS someone within its reach to collect tax from when principal is withdrawn or the surviving spouse dies. A trust run entirely by foreign trustees does not qualify, which is effectively why a QDOT cannot be a foreign trust.

Timely election

The executor elects QDOT treatment on the estate's Form 706, and the election has to be made within one year after the return's due date, including any extensions granted. Once made, the election is irrevocable.

Security for larger trusts

If the assets going into the trust are worth more than $2,000,000, the trust needs extra protection for the IRS. One common way to meet this is keeping foreign real estate under 35% of the trust's value. The alternative is a bond or letter of credit covering the deferred tax.

Most NRI couples run into these rules only once, at the point they sit down to write a will and realize their combined US assets, a house, a 401(k), maybe RSUs from an employer, add up to more than they expected. A financial advisor or estate attorney can check the trustee and funding requirements before the trust is ever needed, rather than leaving an executor to work it out under time pressure after a death.

None of this is free. A corporate trustee usually charges an annual fee to administer the trust, and the legal work to draft and fund it correctly adds a real up-front cost. Weigh that against how much tax is actually being deferred. A QDOT built to cover a modest excess over the exemption can end up costing more in fees over time than the tax it defers.

The three tests NRIs mix up: citizenship, domicile, and residency

Most of the confusion around QDOTs comes from NRIs assuming their US tax residency status settles the question. It does not. Three separate tests apply here, and each answers a different question.

Citizenship decides whether the marital deduction applies automatically. Only a spouse who holds a US passport passes this test. A green card, however long you have held it, does not count.

Domicile decides whether the estate is exposed to US estate tax at all. A green card holder who intends to stay in the US indefinitely is typically domiciled here, which means their worldwide estate, not just US assets, falls under the $15,000,000 exemption and the rules covered in this article. Someone who never intended to stay, even on a long-term work visa, may fall under a different regime entirely, built around a much smaller exemption.

Residency for income tax purposes, the substantial presence test or green card test that decides whether you file Form 1040 as a resident, has no bearing on either of the first two tests. Many NRIs only find this out when they review a green card holder's US ties as part of broader planning, and are surprised that filing taxes as a resident for a decade says nothing about their spouse's inheritance.

If the non-citizen spouse is already in the naturalization process, timing matters more than anything else here. Complete it before the estate tax return is due, typically nine months after death plus any extension, and the marital deduction applies as though they had been a citizen all along, with no QDOT required.

Lifetime gifting works best when there is enough time before either spouse's death. It is a slower path, useful for couples with US-situated assets like company stock that they would rather move over gradually than leave for a trust to sort out later.

Why India-based couples get no treaty relief

NRIs who have used the India-US tax treaty to avoid double income tax often assume something similar exists for estate tax. It does not.

The US has estate or gift tax treaties with a short list of countries: Australia, Austria, Canada, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Japan, the Netherlands, South Africa, Switzerland, and the United Kingdom, according to the IRS's list of estate and gift tax treaties. India is not on it.

That means there is no treaty mechanism to reduce US estate tax exposure. It cuts the other way too, in a sense: India abolished its own estate duty back in 1985, so there is no Indian estate tax to weigh against the US bill. The exposure runs one direction only, from the US, on US-situs assets and, if domiciled, worldwide assets.

A worked example

Say Rahul, now a naturalized US citizen, and Priya, who has held a green card for eight years and remains an Indian citizen, have a combined estate worth $18,000,000 when Rahul dies first. Priya inherits all of it.

Without a QDOT, the estate can shelter $15,000,000 using Rahul's own exclusion. The remaining $3,000,000 does not qualify for the marital deduction because Priya is not a citizen, and estate tax is due on that excess right away, at up to 40%, close to $1,200,000, while Priya is still settling his affairs.

With a properly funded QDOT holding that $3,000,000, the tax is deferred. Priya can draw income from the trust, and the tax comes due only if she withdraws principal or when she herself passes away, by which point she may have become a citizen or planned around it.

Setting up a QDOT

A QDOT can be written into the citizen spouse's estate plan in advance, or set up by the surviving spouse after death, as long as it is funded by the time the estate tax return is filed. Either way, the trust needs a qualifying trustee named from the start, and the executor has to make the election on Form 706 within the statutory window.

Once the trust is running, ongoing principal distributions and the tax due at the surviving spouse's death get reported on Form 706-QDT, a separate return from the regular estate tax filing.

One boundary case worth flagging: everything above assumes the deceased spouse was domiciled in the US. If neither spouse was ever domiciled here, a different set of rules applies, built around a $60,000 exemption instead of $15,000,000, and that is a separate problem with its own planning approach.

Conclusion

Citizenship, not a green card or years of residency, decides whether your spouse inherits without an immediate tax bill.

If your spouse is not a US citizen and your combined estate could exceed $15,000,000, you have three ways to close that gap: a properly funded QDOT, naturalization completed before the estate tax return is due, or steady lifetime gifting within the $194,000 annual limit.

Start by checking each spouse's citizenship and adding up what you own on both sides of the world.
