U.S. Estate Tax Checklist for Nonresident Investors
Foreign investors often model dividend withholding but ignore the separate U.S. estate-tax question. IRS guidance says a nonresident not a citizen can have a Form 706-NA filing requirement when U.S.-situated assets cross the $60,000 threshold, so this belongs in the same account-risk workflow as W-8BEN, Form 1042-S, and broker safety.

Four checks before treating U.S. assets as administratively simple
Who is in scope
IRS instructions use the nonresident-not-a-citizen category for estate-tax purposes when the decedent was neither domiciled in nor a citizen of the United States at death.
$60,000 trigger
IRS guidance says the executor must file Form 706-NA when the date-of-death value of U.S.-situated assets, plus specified gift adjustments, exceeds the $60,000 filing threshold.
U.S.-situated assets
IRS FAQ examples include U.S. real estate, tangible property in the United States, certain intangible property such as U.S. marketable securities, and some U.S. debt or business assets.
Treaty and transfer friction
IRS materials say estate-tax treaties can change treatment, and transfer-certificate workflows may matter before assets can be released cleanly.
Nonresident U.S. estate-tax workflow
Separate estate-tax residence from income-tax residence
IRS FAQ guidance says nonresident status for U.S. estate-tax purposes is determined by domicile at death, and the Form 706-NA instructions describe domicile as living in a place with no definite present intention of later moving.

IRS estate-tax guidance says the computation starts with the total value of assets situated in the United States and generally a separate statement of assets outside the United States; fair market value at the date of death is used, not original cost.

IRS guidance says Form 706-NA is required if the date-of-death value of U.S.-situated assets, together with gift-tax specific exemption and adjusted taxable gifts, exceeds the $60,000 filing threshold. The IRS notes that this threshold is not indexed for inflation.

IRS FAQ examples of U.S.-situated gross-estate property include certain intangible property such as U.S. marketable securities. A brokerage account should therefore be reviewed by asset type, not only by where the investor lives.

IRS guidance says estate-tax treaties often provide more favorable treatment by limiting the asset types treated as U.S.-situated and subject to U.S. estate taxation, but each applicable treaty must be consulted rather than assumed.

IRS transfer-certificate guidance starts by determining whether Form 706-NA is required. It also describes separate request paths depending on whether the return was required, and says one affidavit workflow can take 12 to 18 months after the IRS receives all necessary documentation.

Nonresident estate-tax FAQ
Is this the same as dividend withholding?
No. Dividend withholding is an income-tax cash-flow issue while the investor is alive. This page is about the estate-tax and asset-transfer workflow after death for a nonresident not a U.S. citizen.
Does the $60,000 threshold mean tax is always due?
No. The threshold is a filing trigger for Form 706-NA under IRS guidance. Tax due, deductions, treaty treatment, and transfer-certificate outcomes require a separate fact-specific review.
Why include this on an investing tools page?
Account structure is part of investor risk management. A foreign investor using U.S. stocks should understand W-8BEN, Form 1042-S, broker protection, and the estate-tax administration path before treating the account as operationally simple.
This page is general investor education, not tax advice, legal advice, estate planning advice, or a treaty-position recommendation. Estate-tax domicile, asset situs, treaty protection, transfer certificates, filing duties, and local inheritance rules are fact-specific. Confirm the current facts with a qualified estate or tax professional before relying on any planning assumption.
