Which IRS form is primarily used to report gifts?

The primary form used to report gifts is Form 709, which is specifically designated for reporting gifts and transfers subject to the gift tax. This form allows individuals to declare the value of gifts given during the tax year and to keep track of any potential gift tax liability. It is important for donors to file this form when they make gifts that exceed the annual exclusion limit, ensuring they remain compliant with tax regulations.

The other forms mentioned serve different purposes: Form 706 is used for reporting the estate tax and is filed after the death of the donor; Form 1040 is the individual income tax return form that reports income, deductions, and credits; and Form 1099 is utilized for reporting income from various sources, such as interest, dividends, and freelance work. Each of these forms has distinct purposes and is not suitable for reporting gifts, making Form 709 the clear choice for gift reporting.
