Title 26 › Subtitle Subtitle D— Miscellaneous Excise Taxes › Chapter 42— PRIVATE FOUNDATIONS; AND CERTAIN OTHER TAX-EXEMPT ORGANIZATIONS › Subchapter A— Private Foundations › § 4948
A foreign private foundation pays a tax of 4 percent on its gross investment income from U.S. sources, instead of the excise tax that applies to U.S. foundations. If a foreign foundation gets substantially all of its support (other than investment income) from outside the United States, most of the other private foundation rules do not apply to it. But such a foreign organization loses its tax exemption if it engages in a prohibited transaction after December 31, 1969 — an act that would trigger penalty taxes if it were a U.S. organization. The loss starts in the year the IRS notifies the organization, with notice published in the Federal Register. Starting with the second tax year after that notice, the organization can ask for its exemption back if it convinces the IRS it will not knowingly do it again. While it is not exempt, gifts and bequests made to it after the notice cannot be deducted.
