Title 26 › Subtitle Subtitle D— Miscellaneous Excise Taxes › Chapter 42— PRIVATE FOUNDATIONS; AND CERTAIN OTHER TAX-EXEMPT ORGANIZATIONS › Subchapter A— Private Foundations › § 4948
Foreign private foundations that get substantially all of their support (not counting investment income) from outside the United States must pay a special tax of 4 percent on their gross investment income that comes from U.S. sources. Many domestic rules about private foundations and 501(c)(3) organizations do not apply to these foreign foundations. If such a foreign foundation does a "prohibited transaction" after December 31, 1969, it can lose its tax-exempt status. A prohibited transaction means the kind of act or failure to act that would bring certain penalties or taxes if the group were a U.S. organization. The Secretary will notify the organization and publish that notice the same day, and the organization loses exemption starting with the year of that notice. Under rules set by the Secretary, the group can apply for exemption again beginning with the second taxable year after the notice; if approved, the exemption can be restored for years starting with the year of the claim. Gifts or bequests made to the organization after the public notice, and during years it is not exempt, cannot be claimed as tax deductions under the listed deduction rules (including sections 170, 545(b)(2), 642(c), 2055, 2106(a)(2), and 2522).
