A person who is neither a U.S. citizen nor domiciled in the United States can still have U.S. estate-tax exposure. The analysis generally turns on asset situs, domicile, ownership, treaty coverage, and available deductions.
Why this belongs on the planning calendar
U.S. real estate, shares of U.S. corporations, business interests, debt, and cash can receive different treatment. Brokerage statements do not usually label assets for estate-tax situs.
Cross-border decisions rarely sit in one professional lane. Tax residence, immigration status, account access, investment classification, estate documents, and family timing should be reviewed from the same fact pattern before anyone recommends a transaction.
Build the fact pattern first
Create a short written inventory before comparing solutions. Record the countries, dates, legal owners, account or asset type, relevant currencies, and the professional responsible for confirming each conclusion.
- Citizenship, domicile, residence, and treaty country
- Legal and beneficial ownership of each U.S.-connected asset
- Real estate, securities, business interests, deposits, and debt
- Life insurance, marital planning, deductions, and liquidity
Put the decisions in the right order
Determine domicile, classify situs asset by asset, apply treaty provisions where relevant, and plan ownership and liquidity before death or a transfer.
Keep a decision log showing the assumption, source, owner, due date, and final action. Revisit it when residence, employment, ownership, or family circumstances change.
- Prepare a situs balance sheet
- Review treaty and filing thresholds
- Coordinate U.S. counsel with home-country estate advisors
