In determining the amount of taxable gifts for the “calendar period” (as defined in § 25.2502-1(c)(1)) there may be deducted, in the case of a donor who was a citizen or resident of the United States at the time the gifts were made, all gifts included in the “total amount of gifts” made by the donor during the calendar period (see section 2503 and the regulations thereunder) and made to or for the use of:

The United States, any State, Territory, or any political subdivision thereof, or the District of Columbia, for exclusively public purposes.

Any corporation, trust, community chest, fund, or foundation organized and operated exclusively for religious charitable, scientific, literary, or educational purposes, including the encouragement of art and the prevention of cruelty to children or animals, if no part of the net earnings of the organization inures to the benefit of any private shareholder or individual, if it is not disqualified for tax exemption under section 501(c)(3) by reason of attempting to influence legislation, and if, in the case of gifts made after December 31, 1969, it does not participate in, or intervene in (including the publishing or distributing of statements), any political campaign on behalf of or in opposition to any candidate for public office.

A fraternal society, order, or association, operating under the lodge system, provided the gifts are to be used by the society, order or association exclusively for one or more of the purposes set forth in subparagraph (2) of this paragraph.

Any post or organization of war veterans or auxiliary unit or society thereof, if organized in the United States or any of its possessions, and if no part of its net earnings inures to the benefit of any private shareholder or individual.

In the case of gifts made after December 31, 1969, it must not participate in, or intervene in (including the publishing or distributing of statements), any political campaign on behalf of any candidate for public office.

Its net earnings must not inure in whole or in part to the benefit of private shareholders or individuals other than as legitimate objects of the exempt purposes.
