26 U.S.C. § 4955: Taxes on political expenditures of section 501(c)(3) organizations

There is hereby imposed on each political expenditure by a section 501(c)(3) organization a tax equal to 10 percent of the amount thereof. The tax imposed by this paragraph shall be paid by the organization. There is hereby imposed on the agreement of any organization manager to the making of any expenditure, knowing that it is a political expenditure, a tax equal to 2½ percent of the amount thereof, unless such agreement is not willful and is due to reasonable cause. The tax imposed by this paragraph shall be paid by any organization manager who agreed to the making of the expenditure. In any case in which an initial tax is imposed by subsection (a)(1) on a political expenditure and such expenditure is not corrected within the taxable period, there is hereby imposed a tax equal to 100 percent of the amount of the expenditure. The tax imposed by this paragraph shall be paid by the organization. In any case in which an additional tax is imposed by paragraph (1), if an organization manager refused to agree to part or all of the correction, there is hereby imposed a tax equal to 50 percent of the amount of the political expenditure. The tax imposed by this paragraph shall be paid by any organization manager who refused to agree to part or all of the correction. If more than 1 person is liable under subsection (a)(2) or (b)(2) with respect to the making of a political expenditure, all such persons shall be jointly and severally liable under such subsection with respect to such expenditure. With respect to any 1 political expenditure, the maximum amount of the tax imposed by subsection (a)(2) shall not exceed $5,000, and the maximum amount of the tax imposed by subsection (b)(2) shall not exceed $10,000. The term “political expenditure” means any amount paid or incurred by a section 501(c)(3) organization in any participation in, or intervention in (including the publication or distribution of statements), any political campaign on behalf of (or in opposition to) any candidate for public office. Amounts paid or incurred to such individual for speeches or other services. Travel expenses of such individual. Expenses of conducting polls, surveys, or other studies, or preparing papers or other materials, for use by such individual. Expenses of advertising, publicity, and fundraising for such individual. Any other expense which has the primary effect of promoting public recognition, or otherwise primarily accruing to the benefit, of such individual. If tax is imposed under this section with respect to any political expenditure, such expenditure shall not be treated as a taxable expenditure for purposes of section 4945 or an excess benefit for purposes of section 4958. The term “section 501(c)(3) organization” means any organization which (without regard to any political expenditure) would be described in section 501(c)(3) and exempt from taxation under section 501(a). any officer, director, or trustee of the organization (or individual having powers or responsibilities similar to those of officers, directors, or trustees of the organization), and with respect to any expenditure, any employee of the organization having authority or responsibility with respect to such expenditure. The terms “correction” and “correct” mean, with respect to any political expenditure, recovering part or all of the expenditure to the extent recovery is possible, establishment of safeguards to prevent future political expenditures, and where full recovery is not possible, such additional corrective action as is prescribed by the Secretary by regulations. the date of mailing a notice of deficiency under section 6212 with respect to the tax imposed by subsection (a)(1), or the date on which tax imposed by subsection (a)(1) is assessed. The amendments made by this section [enacting section 4958 of this title and amending this section and sections 4963, 6213, 7422, and 7454 of this title] (other than subsection (b)) [amending section 501 of this title ] shall apply to excess benefit transactions occurring on or after September 14, 1995 . The amendments referred to in paragraph (1) shall not apply to any benefit arising from a transaction pursuant to any written contract which was binding on September 13, 1995 , and at all times thereafter before such transaction occurred.”
