Most people I talk to about their IRS problem have already built the worst-case scenario in their head. The reality is usually much more manageable. I'm Darrin Mish, and I've been representing taxpayers before the IRS for 32 years. Here's what actually tends to happen.<\/p>\n
A nonresident alien holds U.S. stocks, U.S. real estate, or U.S. business interests. The investment may be substantial. The taxpayer pays U.S. income tax on dividends and rental income each year. Then the taxpayer dies. The estate discovers that U.S. estate tax applies – with an exemption so small that the tax becomes a major issue on almost any meaningful estate.<\/p>\n
The U.S. estate tax for nonresident aliens is one of the most overlooked tax exposures in international wealth holding. Understanding the rules before death is essential because most planning opportunities require lifetime action.<\/p>\n
Under IRC Section 2101, the estate of a nonresident alien is subject to U.S. estate tax on the value of U.S.-situs property owned at death. The tax applies regardless of where the decedent lived, what their citizenship was, or where the heirs reside.<\/p>\n
U.S.-situs property includes:<\/p>\n
U.S. real estate located in the United States.<\/p>\n
Tangible personal property located in the United States at death.<\/p>\n
U.S. corporate stocks – stocks of corporations organized in the United States.<\/p>\n
U.S. partnership interests (with specific rules and exceptions).<\/p>\n
U.S. debt instruments (with specific exemptions, particularly the portfolio interest exemption for certain debt).<\/p>\n
Other U.S.-situs property as defined in the regulations.<\/p>\n
The exemption for nonresident aliens is approximately $60,000 of U.S.-situs property. This number has not been adjusted for inflation since 1988 when it was set at $60,000.<\/p>\n
For comparison, U.S. citizens and residents have an exemption of approximately $13.99 million for 2026 (indexed annually). The difference is enormous – 233 times larger for U.S. citizens.<\/p>\n
A nonresident alien dying with $1 million of U.S.-situs property faces estate tax on $940,000 at rates up to 40 percent – approximately $329,000 in tax. The same property held by a U.S. citizen would owe zero estate tax (well below the U.S. citizen exemption).<\/p>\n
The U.S. estate tax for nonresident aliens uses the same graduated rate schedule as for U.S. citizens. Rates run from 18 percent on the first $10,000 above the exemption to 40 percent on amounts above $1 million.<\/p>\n
For most meaningful estates, the effective rate is at or near the top 40 percent rate because the brackets fill quickly. The graduation does not provide meaningful relief above the lowest brackets.<\/p>\n
This is the most common estate tax trap. A foreign investor builds a U.S. stock portfolio – blue chips, ETFs, mutual funds, individual positions. The investment grows over time. The investor never thinks about U.S. estate tax.<\/p>\n
At death, the U.S. stocks are U.S.-situs property under IRC Section 2104(b). The estate is subject to U.S. estate tax on the value above the $60,000 exemption.<\/p>\n
The estate must file Form 706-NA, “United States Estate (and Generation-Skipping Transfer) Tax Return – Estate of Nonresident Not a Citizen of the United States,” within 9 months of death. The filing requires detailed identification of all U.S.-situs property.<\/p>\n
The estate must obtain a transfer certificate from the IRS before the broker can release the U.S. stocks to the heirs. Without the certificate, the broker is personally liable for any unpaid estate tax.<\/p>\n
The U.S. has estate tax treaties with approximately 15 countries: Australia, Austria, Canada, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Japan, Netherlands, Norway, South Africa, Switzerland, and the United Kingdom.<\/p>\n
The treaties generally do one of two things:<\/p>\n
Provide a larger exemption for residents of the treaty country. Some treaties extend the U.S. citizen exemption to nonresident aliens from the treaty country, or provide a proportional exemption based on the ratio of U.S. assets to worldwide assets.<\/p>\n
Allocate taxing rights between the U.S. and the treaty country to prevent double taxation. The treaties typically give the U.S. primary taxing authority on U.S.-situs property, with the treaty country providing a credit or exemption.<\/p>\n
For nonresident aliens from treaty countries, the practical estate tax exposure may be substantially reduced. For nonresident aliens from non-treaty countries, the full domestic law applies.<\/p>\n
Several strategies can reduce or eliminate U.S. estate tax exposure for nonresident alien investors. Each has its own complications.<\/p>\n
Hold U.S. assets through a non-U.S. corporation. The decedent owns shares of a foreign corporation, not the underlying U.S. assets. Foreign corporate stock is not U.S.-situs property. The estate tax issue does not apply.<\/p>\n
The catch: the foreign corporation itself may face U.S. tax issues on its U.S. holdings – branch profits tax, FIRPTA on U.S. real estate, withholding on U.S.-source income. The corporate structure requires ongoing compliance and adds operating cost.<\/p>\n
Hold U.S. real estate through an irrevocable foreign trust. Properly structured, the trust holds the U.S. real estate for the family’s benefit. The decedent has no estate tax exposure because the property is not in the decedent’s estate.<\/p>\n
The trust structure requires careful drafting and ongoing administration. Income tax consequences of the trust must be analyzed.<\/p>\n
Lifetime gifts of U.S. intangible property. As discussed in the gift tax analysis, lifetime gifts of U.S. stocks by nonresident aliens are not subject to U.S. gift tax. Transferring U.S. stocks to children or trusts during life eliminates the estate tax exposure on those assets.<\/p>\n
Convert U.S. real estate ownership before death. Transferring U.S. real estate to a foreign corporation or trust during life shifts the situs for estate tax purposes. Properly structured, the gift may not trigger U.S. gift tax (depending on structure).<\/p>\n
Use of portfolio interest exempt debt. Loans to U.S. borrowers from nonresident alien lenders, structured under the portfolio interest rules of IRC Section 871(h), can generate U.S.-source interest income without U.S. withholding and without U.S. estate tax exposure on the debt instrument itself.<\/p>\n
If a nonresident alien dies owning U.S.-situs property exceeding $60,000 in value, the estate must file Form 706-NA within 9 months of death. Extensions are available but the underlying tax is due on the original due date.<\/p>\n
The form requires:<\/p>\n
Inventory of all U.S.-situs property.<\/p>\n
Valuations of each asset at the date of death.<\/p>\n
Calculation of the U.S. estate tax due.<\/p>\n
Information about heirs and distributions.<\/p>\n
The estate must also obtain transfer certificates from the IRS for U.S. stocks, U.S. partnership interests, and other U.S.-situs property before the property can be released to heirs.<\/p>\n
The personal representative of the foreign decedent’s estate is responsible for filing Form 706-NA and paying the U.S. estate tax. For estates with substantial U.S. assets, this often requires retaining U.S. counsel and a U.S. accountant familiar with the procedures.<\/p>\n
The personal representative is personally liable for unpaid U.S. estate tax to the extent of assets distributed before the tax is paid. This makes proper filing and payment essential before any distributions are made.<\/p>\n
For estates without sufficient liquid U.S. assets to pay the tax, the estate may need to sell U.S. property to fund the tax payment. This can be problematic when the U.S. assets are illiquid (real estate, private business interests) or when sale would trigger additional income tax.<\/p>\n
Beyond the estate tax, the foreign decedent’s estate may have U.S. income tax obligations during the administration period. Income earned on U.S. assets during administration is taxable to the estate.<\/p>\n
The estate files Form 1041 (U.S. Income Tax Return for Estates and Trusts) for income earned during the administration period. The estate may need an EIN, which can be obtained from the IRS.<\/p>\n
Distributions to heirs during administration are reported on Schedule K-1 to the heirs, who include the income on their own returns. Foreign heirs receiving distributions of U.S.-source income may face additional withholding.<\/p>\n
First, identify which U.S. assets create estate tax exposure. U.S. real estate, U.S. stocks, U.S. partnership interests, and certain U.S. debt are the main categories.<\/p>\n
Second, evaluate whether the country of residence has a U.S. estate tax treaty. Treaty residents may have substantially better exemptions.<\/p>\n
Third, structure U.S. asset holdings to minimize estate tax exposure. Foreign corporations, trusts, lifetime gifts, and portfolio debt all have roles depending on the specifics.<\/p>\n
