Key Takeaways

  • Form 706-NA applies to U.S.-situs assets of certain nonresident noncitizens, not to worldwide assets generally.
  • U.S.-situs property includes more than just U.S. real estate.
  • Asset classification is a major part of the estate-tax file.
  • The return should be built around a clear situs map.

Nonresident estate tax starts with situs, not with worldwide wealth

The IRS estate-tax FAQs for nonresidents say that a nonresident not a citizen of the United States is subject to U.S. estate taxation only with respect to U.S.-situated assets. That is the conceptual anchor for Form 706-NA. The return is not a worldwide estate return like many people expect. It is a U.S.-situs estate return.

The U.S.-situs list is broader than just real estate

The IRS says U.S.-situated gross estate property can include U.S. real estate, all tangible property located in the United States, certain intangible property such as U.S. marketable securities, debt obligations of U.S. persons, and a U.S. trade or business. That means foreign families can have an estate-tax problem even without U.S. homes if they hold other U.S.-situs assets.

The return is really a situs-mapping exercise

A strong Form 706-NA file separates included U.S.-situs assets from excluded property and documents why each item belongs where it does. The hardest cases are often not valuation fights. They are classification fights about whether an asset was actually situated in the United States at death.

Frequently Asked Questions

Does a nonresident file Form 706-NA for all assets worldwide?

No. The U.S. estate tax for a nonresident not a citizen generally applies only to U.S.-situated assets.

Can U.S. securities create a 706-NA issue?

Yes. The IRS says certain intangible property, including U.S. marketable securities, can be part of the U.S.-situated gross estate.

What is the biggest practical challenge in a 706-NA case?

Often it is determining which assets are U.S.-situs and which are excluded, not merely filling in the form.
