Marriage is a beautiful partnership, and when one spouse is a non-U.S. citizen, estate planning becomes more complex but also more crucial. Without proper planning, tax burdens and inheritance issues can create unintended challenges for your loved ones. Understanding the tax laws, inheritance rules, and strategic solutions available can help protect your wealth and ensure a smooth transfer of assets.
Understanding Residency vs. Domicile
For estate planning purposes, it’s important to distinguish between residency and domicile:
- Residency: The IRS determines U.S. tax residency based on the substantial presence test, which calculates the number of days a person has spent in the U.S. over a three-year period.
- Domicile: For gift and estate tax purposes, domicile is key. A person is domiciled in the U.S. if they live there with no present intention of leaving. A permanent resident (green card holder) typically establishes domicile in the U.S.
Why does this matter? Because a U.S. domiciliary is subject to estate and gift tax on their worldwide assets, while a non-domiciliary is taxed only on their U.S.-based assets.
Foreign Assets and Inheritance Challenges
When a non-U.S. citizen owns assets abroad, different inheritance laws may apply. Many countries do not recognize U.S. wills or trusts, meaning:
- A U.S. will may not be valid for assets held in another country.
- Foreign laws might dictate how property is distributed, regardless of U.S. estate plans.
- Some countries don’t recognize trusts as legal entities, affecting wealth protection strategies.
To avoid complications, it may be necessary to create multiple wills—one for the U.S. and others tailored to the laws of the countries where assets are held. Therefore, consulting an attorney familiar with estate planning is essential.
Tax Considerations for Non-Citizen Spouses
One of the biggest concerns in estate planning for a non-U.S. citizen spouse is federal estate and gift tax laws. When both spouses are U.S. citizens, they can transfer unlimited assets between each other tax-free under the unlimited marital deduction. However, this deduction does not apply when one spouse is a non-U.S. citizen.
Gift Tax Limits for Non-Citizen Spouses
If a U.S. citizen spouse wants to transfer assets to a non-U.S. citizen spouse, there are limits:
✅ Annual Gift Tax Exclusion (2025): $190,000 per year (adjusted for inflation).
✅ Lifetime Gift & Estate Tax Exemption (2025): $13.99 million for U.S. citizens.
🚫 No Unlimited Marital Deduction for Non-Citizen Spouses.
Without proper planning, transferring large amounts of assets could trigger significant gift or estate taxes.
What Happens When a U.S. Citizen Spouse Passes Away?
If a U.S. citizen spouse names a non-U.S. citizen spouse as a beneficiary, the federal estate tax applies once the exemption threshold is exceeded. This means:
- Assets inherited by a non-citizen spouse are subject to estate tax (up to 40%) on amounts above the exemption limit.
- The federal government does not want wealth to leave the U.S. untaxed.
To mitigate this issue, estate planning attorneys recommend applying for citizenship and using a Qualified Domestic Trust (QDOT).
How a Qualified Domestic Trust (QDOT) Works
A QDOT allows a U.S. citizen spouse to pass assets to a non-U.S. citizen spouse without immediate estate tax liability. Instead:
✔ The trust receives the inheritance instead of the spouse directly.
✔ The non-citizen spouse is the sole beneficiary and can receive income distributions.
✔ Estate taxes are deferred until distributions of principal are made.
A QDOT is a powerful tool that allows non-citizen spouses to inherit assets without an immediate estate tax burden, preserving wealth for the family.
Planning Strategies for Cross-Border Couples
For couples where one spouse is a non-U.S. citizen, here are two key strategies:
- Applying for U.S. Citizenship
If a non-U.S. citizen spouse becomes a U.S. citizen before the estate tax return is due (within nine months after death, plus a six-month extension), the unlimited marital deduction applies. However, waiting until death to apply for citizenship may not be practical.
- Establishing a QDOT
If citizenship isn’t an option, creating a QDOT before death ensures tax-efficient wealth transfer. A properly structured QDOT can be set up through:
- A will or trust established before death.
- A post-death election within 27 months after the U.S. citizen spouse’s death.
Final Thoughts: Secure Your Family’s Future
Estate planning is always essential, but when a spouse is a non-U.S. citizen, the stakes are even higher. Proper planning with an experienced estate attorney ensures:
✅ Wealth is transferred tax-efficiently.
✅ Inheritance laws in multiple countries are considered.
✅ Your loved ones are financially protected.
