Non-Citizen Spouse and Your Home: The Estate Tax Trap Most Couples Miss

Quick answer (updated October 2026): Estate tax rules for a house with a non-citizen spouse are different. The unlimited marital deduction generally isn't available when the surviving spouse isn't a US citizen, unless assets pass through a qualified domestic trust (QDOT). Jointly owned property is fully included unless the surviving spouse proves contribution. Nonresident non-citizens face a $60,000 US filing threshold.

Most couples in our community never think about estate tax when they buy. One spouse naturalized last year; the other is on an H-4 or still waiting on EB-2 India dates. They pick "joint tenancy" because it sounds like what married people do.

For many households that's fine, because the federal exclusion for US-domiciled estates is high. But the rules change sharply when the surviving spouse isn't a citizen, and they change even more if you later move back to India and keep the house. This guide covers the three traps, how title choices interact with them, and when to bring in an estate attorney. It's education, not tax advice.

Trap 1: No unlimited marital deduction for a non-citizen spouse

Between US-citizen spouses, the estate tax marital deduction is unlimited: everything can pass to the surviving spouse with no federal estate tax at the first death. That's the rule most online articles assume.

When the surviving spouse is not a US citizen, the IRS says the unlimited marital deduction is generally not available. The idea is that a non-citizen spouse could leave the US with the assets before the second death, and the IRS would never collect.

This matters even if the spouse who dies is a citizen. Example (hypothetical): Sanjay, a naturalized citizen, dies. His wife Kavitha holds an H-1B. Their house, his 401(k) and brokerage account would normally pass to her free of estate tax under the marital deduction. Because Kavitha isn't a citizen, that deduction is generally unavailable, and Sanjay's estate relies on his own exclusion instead.

Trap 2: The jointly owned house is counted in full

Married citizens who own a home as joint tenants generally include only half the value in the first spouse's estate. With a non-citizen surviving spouse, the IRS says the value of jointly held property must be reported in full, unless the estate proves, among other grounds, that the property was acquired with consideration belonging to the surviving spouse.

In plain terms: if Kavitha paid part of the down payment and mortgage from her own earnings, the estate can exclude that share, if it can prove it. If nobody kept records, the whole house may be counted in Sanjay's estate.

What you can document	Effect on first spouse's estate (non-citizen survivor)
No records of who paid	Full value of the joint home generally included
Survivor paid 40% of down payment and payments, with statements	Estate can argue to exclude the survivor's contribution share
Survivor received their share as a gift from the decedent	Gifted funds generally don't count as the survivor's own contribution

Practical step: pay your share of the down payment and mortgage from accounts in your own name and keep the statements. A loan officer sees your sourcing documents anyway; save a copy for your estate file.

Trap 3: Nonresident estate tax and the $60,000 threshold

Now say you both move back to Bengaluru and keep the Plano house as a rental. At that point you may be nonresident non-citizens for US estate tax purposes. The IRS rule: the executor must file Form 706-NA if the decedent's US-situated assets exceed $60,000 at death. Estates filing Form 706-NA get a unified credit of $13,000, far smaller than what US-domiciled estates receive.

A US house is a US-situated asset. So a $500,000 equity share in a rental can create a real US estate tax bill and a filing obligation for heirs in India. Estate tax treaties can sometimes help, and the IRS notes they often provide more favorable treatment to nonresidents, so ask your attorney whether one applies to you.

Note that "resident" for estate tax means domicile, a facts-and-circumstances test about where you intend to live permanently. It isn't the same as your visa status or your income tax residency. If you're planning a move, read what happens to your mortgage if you leave the US and, when you eventually sell, FIRPTA withholding when moving to India.

Talk to a loan officer who's seen this before: Title is chosen at closing and is harder to change later. Book a free call and we'll make sure your vesting options line up with your estate attorney's advice before you sign.

QDOT home basics

A qualified domestic trust (QDOT) is the tool the tax code provides to restore the marital deduction for a non-citizen surviving spouse. Property passing through a QDOT can qualify for the marital deduction under the rules of section 2056A. According to the IRS, the QDOT must be established before the decedent's death or before the estate tax return is filed.

What a QDOT does and doesn't do:

• Defers, doesn't erase. Estate tax is generally deferred, and certain distributions of principal and the assets remaining at the surviving spouse's death can be taxed.

• Requires a US trustee and specific terms.

• Can hold a house. A home can be held in or pass to a QDOT, but there are special rules for residences, and having a mortgage on it complicates administration.

• Citizenship later can help. The IRS describes relief from QDOT tax in certain cases when the surviving spouse becomes a citizen.

This is specialist work for an estate attorney who handles cross-border families.

Estate tax, a non-citizen spouse and your house: title choices

Title option	Estate tax angle with a non-citizen spouse	Mortgage note
Sole ownership (citizen spouse)	Fully in citizen's estate; marital deduction generally unavailable for transfer to non-citizen survivor	Non-borrowing spouse may still need to sign in some states
Joint tenancy with right of survivorship	Full value included unless survivor proves contribution	Common default; both usually sign
Tenants in common	Each owns a defined share; decedent's share passes by will	Good when contributions are unequal
Community property (in those states)	State law characterizes ownership; get attorney advice	Spouse signature requirements vary
Revocable living trust	Avoids probate; can be drafted with QDOT provisions	Many lenders accept trust vesting; confirm

A note on gifts between spouses

Adding a non-citizen spouse to title, or paying their share for them, can be a gift for US gift tax purposes. Gifts to a non-citizen spouse don't get the unlimited marital deduction either; there's a separate annual exclusion amount for them that changes yearly. Ask your CPA before retitling.

What the rules actually say

• IRS Internal Revenue Manual 4.25.4: the unlimited marital deduction is generally not available for property passing to a non-citizen spouse; a transfer through a qualified domestic trust (IRC 2056A) can qualify, and the QDOT must be established before death or before Form 706 is filed.

• IRM 4.25.4: for jointly held property with a non-citizen surviving spouse, the full value is reported unless the estate shows, among other grounds, it was acquired with consideration belonging to the surviving spouse.

• IRS, "Some nonresidents with U.S. assets must file estate tax returns": Form 706-NA is required if US-situated assets exceed $60,000; estate tax treaties often provide more favorable treatment. IRM 4.25.4: unified credit of $13,000 for Form 706-NA estates, as of October 2026.

Frequently Asked Questions

Q: Can I leave my house to my non-citizen spouse tax-free?
A: Not automatically. The unlimited marital deduction is generally unavailable when the surviving spouse isn't a US citizen. Your own estate tax exclusion may still cover the house, and a qualified domestic trust can restore the deduction. An estate attorney can tell you which applies.

Q: What is a QDOT and does it work for a home?
A: A qualified domestic trust lets assets passing to a non-citizen spouse qualify for the marital deduction, deferring estate tax. It requires a US trustee and specific terms. A home can be held in one, but residences and mortgages add complexity, so use an experienced estate attorney.

Q: What is the $60,000 estate tax rule for nonresidents?
A: If a nonresident non-citizen dies owning US-situated assets worth more than $60,000, including a US house, the executor must file Form 706-NA. Those estates get a much smaller credit than US-domiciled estates. Treaties may help in some cases.

Q: Does joint tenancy protect my non-citizen spouse?
A: It avoids probate, but for estate tax the full value of the joint home is generally included in the first spouse's estate unless the surviving spouse proves they contributed. Keep records showing each spouse paid their share from their own funds.

Q: Should I talk to an estate attorney before buying a house?
A: If one spouse isn't a citizen and your assets are significant, or you might leave the US and keep the home, yes. Title is chosen at closing. A short consultation beforehand is cheaper than retitling and planning later.
