In economics, a gift tax is the tax on money or property that one living person gives to another. Items received upon the death of another are considered separately under the inheritance tax. Many gifts are not subject to taxation because of exemptions given in tax laws. The gift tax amount varies by jurisdiction, and international comparison of rates is complex and fluid.

A gift or a present is the transfer of something without the expectation of payment. Although gift-giving might involve an expectation of reciprocity, a gift is meant to be free. In many human societies, the act of mutually exchanging money, goods, etc. may contribute to social cohesion. Economists have elaborated the economics of gift-giving into the notion of a gift economy. By extension the term gift can refer to anything that makes the other happier or less sad, especially as a favor, including forgiveness and kindness.

When material objects are given as gifts, in many cultures they are traditionally packaged in some manner. For example, in Western culture, gifts are often wrapped in wrapping paper and accompanied by a gift note which may note the occasion, the recipient's name, and the giver's name. In Chinese culture, red wrapping connotes luck.

The occasion may be:

At common law, for a gift to have legal effect, it was required that there be (1) intent by the donor to give a gift, and (2) delivery to the recipient of the item to be given as a gift.
