Gift tax in the United States
If a person is a non-resident alien for purposes of gift tax, taxation of gifts is determined in a different way. If the property is not located in the U.S., there is no gift tax. If it is intangible property, such as shares in U.S. corporations and interests in partnerships or LLCs, there is no gift tax.
Excise tax in the United States
Traditionally the federal government has left property taxes and sales taxes to the states and local governments for their revenue. Tariffs or customs duties on imported goods are essentially the only property taxes imposed by the U.S. federal government. Tariffs can be set only by the federal government, not by any state or local jurisdiction. For U.S. constitutional law purposes, a customs duty or tariff is nominally in a separate category from an excise tax. Excise taxes can be (and are) set by federal, state and local jurisdictions.
