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.
Taxation in the United Kingdom
Gifts made more than seven years prior to death are not taxed; if they are made between three and seven years before death a tapered inheritance tax rate applies. There are some important exceptions to this treatment: the most important is the "reservation of benefit rule", which says that a gift is ineffective for inheritance tax purposes if the giver benefits from the asset in any way after the gift (for example, by gifting a house but continuing to live in it).
