For most people, the limits on charitable contributions don't apply. Only if you contribute more than 20% of your adjusted gross income to charity is it necessary to be concerned about donation limits. If the contribution is made to a public charity, the deduction is limited to 50% of your contribution base. For example, if you have an adjusted gross income of $100,000, your deduction limit for that year is $50,000. The rules on 20% limits and 30% limits are way too complicated to delve into in this space.
If you are interested in giving large gifts to family members or friends, it is important to know how much you can give without incurring a tax penalty.

If you want to give money to a child or grandchild and you are married, each spouse can give a gift of $14,000 for a total of $28,000.
