22 U.S. Code § 3307 - Exemption from taxation
The Institute, its property, and its income are exempt from all taxation now or hereafter imposed by the United States (except to the extent that section 3310(a)(3) of this title requires the imposition of taxes imposed under chapter 21 of title 26, relating to the Federal Insurance Contributions Act) or by any State or local taxing authority of the United States.
The Federal Insurance Contributions Act, referred to in subsec.

1986—Pub. L. 99–514 substituted in subsecs. (a) and (b) “Internal Revenue Code of 1986” for “Internal Revenue Code of 1954”, which for purposes of codification was translated as “title 26” thus requiring no change in text.
