26 CFR § 20.2209-1 - Certain residents of possessions considered nonresidents not citizens of the United States.
As used in this part, the term “nonresident not a citizen of the United States” is considered to include a decedent dying after September 14, 1960, who, at the time of his death, was domiciled in a possession of the United States and was a United States citizen, and who acquired his United States citizenship solely by reason of his being a citizen of such possession or by reason of his birth or residence within such possession. The estate of such a decedent is, therefore, subject to the tax imposed by section 2101 which is the tax applicable in the case of a “nonresident not a citizen of the United States.” See paragraph (a)(2) of § 20.0-1 and § 20.2208-1 for further information relating to the application of the Federal estate tax to the estates of decedents who were residents of possessions of the United States. The application of this section may be illustrated by the following examples and the example set forth in § 20.2208-1. In each of the following examples the decedent is deemed a “nonresident not a citizen of the United States” and his estate is subject to the tax imposed by section 2101 since the decedent died after September 14, 1960, but would not have been so deemed and subject to such tax if the decedent had died on or before September 14, 1960.
