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.
Estate tax in the United States
The Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 became law on December 17, 2010. The 2010 Act changed, among other things, the rate structure for estates of decedents dying after December 31, 2009, subject to certain exceptions. It also served to reunify the estate tax credit (aka exemption equivalent) with the federal gift tax credit (aka exemption equivalent). The gift tax exemption is equal to $5,250,000 for estates of decedents dying in 2013, and $5,340,000 for estates of decedents dying in 2014.
