Code of Federal Regulations Title 26. Internal Revenue § 26.1.509(b)–1 Continuation of private foundation status

(a) In general.If an organization is a private foundation (within the meaning of section 509(a)) on October 9, 1969, or becomes a private foundation on any subsequent date, such organization shall be treated as a private foundation for all periods after October 9, 1969, or after such subsequent date, unless its status as such is terminated under section 507. Therefore, if an organization was described in section 501(c)(3) and was a private foundation within the meaning of section 509(a) on October 9, 1969, it shall be treated as a private foundation for all periods thereafter, even though it may also satisfy the requirements of an organization described in some other paragraph of section 501(c). For example, if on October 9, 1969, an organization was described in section 501(c)(3), but because of its activities, it could also have qualified as an organization described in section 501(c)(4), such organization will continue to be treated as a private foundation, if it was a private foundation within the meaning of section 509(a) on October 9, 1969.

(b) Taxable private foundations.If an organization is a private foundation on October 9, 1969, and it is determined that it is not exempt under section 501(a) as an organization described in section 501(c)(3) as of any date after October 9, 1969, such organization, even though it may operate thereafter as a taxable entity, will continue to be treated as a private foundation unless its status as such is terminated under section 507. For example, X organization is a private foundation on October 9, 1969. It is subsequently determined that, as of July 1, 1972, X is no longer exempt under section 501(a) as an organization described in section 501(c)(3) because, for example, it has not conformed its governing instrument pursuant to section 508(e). X will continue to be treated as a private foundation after July 1, 1972, unless its status as such is terminated under section 507. However, if an organization is not exempt under section 501(a) as an organization described in section 501(c)(3) on October 9, 1969, then it will not be treated as a private foundation within the meaning of section 509(a) by reason of section 509(b), unless it becomes a private foundation on a subsequent date.
