Interplay Between the Limitations on Deductions for Contributions to Public Charities and Private Foundations. As previously discussed, the income tax charitable deduction for contributions of long-term capital gain property to a public charity is subject to a limit of 30 percent of the donorâs contribution base. This limit is reduced to 20 percent in the case of such contributions to a private foundation.
Contributions which do not exceed the annual exclusion amount (now $13,000 per donee per year) are not implicated since, even if they are subject to gift tax, they are specifically excluded. However, contributions exceeding $13,000 each year to a social welfare organization may risk a gift tax. If gift tax is imposed on contributions to social welfare organizations which exceed the $13,000 annual exclusion, there may be some potential defenses.
