Generally, Form 709: U.S. Gift (and Generation-Skipping Transfer) Tax Return is required if any of the following apply: An individual makes one or more gifts to any one person (other than his or her citizen spouse) that are more than the annual exclusion for the year.
Any gifts exceeding $19,000 in a year must be reported and contribute to your lifetime exclusion amount. You can gift up to $13.99 million over your lifetime without paying a gift tax on it (as of 2025). The IRS adjusts the annual exclusion and lifetime exclusion amounts every so often.

The donor is responsible, and the form reports large gifts that may use up their lifetime exemption, though tax is usually not owed unless the lifetime limit is exceeded.
