Gifts you make to people are not tax deductible. However, it’s good to know that the recipient of a gift is not subject to income tax on it, regardless of the size of the gift. If the gift is more than the annual gift tax exclusion ($15,000 in 2019), a donor (the person who gives the gift) may have to file a gift tax return, and in rare cases, pay gift tax. But this has no impact on income taxes.
