In general, a private foundation that wishes to make a grant to a foreign organization is required to either: (1) verify that the foreign organization has been approved by the IRS as a 501(c)(3) public charity; (2) exercise “expenditure responsibility” over the grant; or (3) make a good faith determination that the foreign organization is equivalent to a United States public charity (typically by relying on an opinion letter from a qualified tax practitioner). Thus, it is not always necessary to obtain an equivalency determination, but this is generally the safest option for a private foundation in the event the grantee organization has not received an approval letter by the IRS.

Private operating foundations are a special type of private foundation that generally devote most of their earnings and assets to running charitable programs directly, in contrast to standard private foundations that mainly make grants (technically referred to as “private non-operating foundations”). Private operating foundations are generally subject to more favorable rules than other types of private foundations, so this status is usually preferable if your organization qualifies.
