Non-U.S. citizens face unique estate planning challenges
Estate plans are often designed around rules that assume spouses and other family members are U.S. citizens. When one spouse isn’t a citizen — or when an individual owns U.S. property but lives abroad — those assumptions can create unexpected estate tax consequences.
Citizenship, domicile, and the location and type of property owned can all affect how U.S. gift and estate taxes apply. For families with international connections, understanding these distinctions is an important first step toward avoiding unnecessary taxes.
Domicile matters more than you might think
Noncitizens can become subject to U.S. gift and estate taxes if they’re domiciled in the United States. Under IRS guidelines, an individual becomes domiciled in a country “by living there, for even a brief period of time, with no definite present intention of later removing therefrom.”
The IRS considers several factors in determining “present intention,” including:
- The amount of time spent in the United States;
- Green card or visa status;
- Location of business interests and residences;
- Location of health care providers, jobs, places of worship and community ties;
- Place where vehicles are registered and where the individual is licensed to drive;
- Place where the person is registered to vote; and
- The domiciles of friends and family members.
Noncitizens who are deemed to be domiciled in the United States are subject to U.S. gift and estate taxes on their worldwide assets, much like U.S. citizens. And, like U.S. citizens, these U.S. “domiciliaries” are eligible for the federal gift and estate tax exemption ($15 million for 2026) and the gift tax annual exclusion ($19,000 per recipient for 2026).
Marriage to a noncitizen changes the rules
A significant difference between U.S. citizens and noncitizens, and a potential tax trap for the unwary, is that the marital deduction isn’t available for transfers to noncitizens, even if they’re U.S. domiciliaries. Ordinarily, married couples can transfer an unlimited amount of assets between each other — during their lifetimes or at death — without triggering gift or estate taxes. However, estate planning strategies that rely on the marital deduction may not be available to noncitizen domiciliaries.
There are ways to manage this limitation. For example, during life, an individual can make tax-free gifts to his or her noncitizen spouse using a special annual exclusion. For 2026, up to $194,000 of qualifying present-interest gifts may be transferred to a noncitizen spouse without gift tax. This is substantially higher than the regular $19,000 annual exclusion. Larger transfers may also be possible by using the donor spouse’s available gift and estate tax exemption.
Beware of a tax trap
A person who’s neither a U.S. citizen nor a U.S. domiciliary — that is, a “nonresident alien” — is subject to U.S. gift and estate taxes only on assets that are “situated” in the United States. Intangible property — such as corporate stock, bonds or promissory notes — is generally deemed to be situated in the United States for estate tax purposes (but typically not for gift tax purposes) if it’s issued by a domestic corporation or by a U.S. citizen or the U.S. government.
Here’s where the potential tax trap comes into play: The exemption amount for U.S.-situated assets owned by nonresident aliens is only $60,000, compared with $15 million for U.S. citizens or domiciliaries. Depending on the value of a person’s property in the United States, this can result in significant gift and estate taxes.
In some cases, tax treaties between the United States and a nonresident alien’s country of citizenship may provide some relief. Otherwise, one strategy to avoid these taxes may be holding the assets through a properly structured and operated foreign corporation.
