If you’ve given money or property to someone as a gift, you may owe federal gift tax, but in many cases, you will not. For example, there is usually no tax if you make a gift to your spouse or a charity. If you make a gift to someone else, the gift tax usually does not apply until the value of the gifts you give that person exceeds the annual exclusion for the year.
In 2021, you can give any amount up to $15,000 per person per year with no gift tax liability. However, gifts exceeding that amount are counted against a gift tax exemption of $11,700,000 and are subject to gift tax. At your death, these gifts could become your taxable estate (with credit for gift tax paid).
