7  Foundations, Trusts, and Grant-Making Organizations

This chapter explains NCCS’s taxonomy for foundations, trusts, and grant-making organizations:

[INSERT TABLE]

Each type of organization is described in detail below.

7.1 Not a foundation

Description. Organizations in this category are not foundations, trusts, or grant-making organizations.

Foundation/trust/grant-making organization status. Organizations in this category are not foundations, trusts, or grant-making organizations.

Subsector. These organizations can be 501(c)(3) or 501not3 organizations. (See Appendix A for more details about 501(c)(3) vs. 501not3 organizations).

Public or private foundation status. These organizations are neither public nor private foundations.

Exemption from federal income taxes. These organizations are exempt from federal income tax.

Eligibility to receive tax-deductible charitable contributions. Some organizations in this category (501(c)(3) organizations) are eligible to receive tax-deductible charitable contributions, and others (501not3 organizations) are not. (See Appendix A for more details about 501(c)(3) vs. 501not3 organizations).

Identification. We can identify organizations that are not foundations, trusts, or grant-making organizations using SUBSECCD (subsection code), LEVEL 1 (public charity or private foundation?) and NTEECC (NTEECC primary purpose). Values of not 90, 91, or 92 for SUBSECCD indicate that an organization is not a 4947(a)(1) charitable trust or a 4947(a)(2) split-interest charitable trust; values of not PF (private foundation) and not U (unknown) for LEVEL1 indicate that an organization is a not private foundation; and values of not T20, T21, T22, T23, T30, T31, T40, T50, T70, T90, T99, A11, B11, C11, D11, E11, F11, G11, H11, I11, J11, K11, L11, M11, N11, O11, P11, Q11, R11, S11, T11, U11, V11, W11, X11, Y11, A12, B12, C12, D12, E12, F12, G12, H12, I12, J12, K12, L12, M12, N12, O12, P12, Q12, R12, S12, T12, U12, V12, W12, X12, or Y12 for NTEECC indicate that an organization is not a general private foundation, private corporate foundation, private grantmaking foundation, private operating foundation, public foundation, community foundation, mobilizing social sector resources and support foundation, federated giving program, unclassified foundation, subsector-specific foundation, public single organization support organization, or public multi organization support organization.

7.2 Mobilizing social sector resources and support non-foundation

Description. Organizations in this category mobilize social sector resources and support (according to their NTEE codes), but they theoretically are not foundations. [Note: See “Foundation/trust/grant-making organization status.”] They “encourage people to volunteer” or are “concerned with civil society, philanthropy, and the nonprofit sector” and “seek to promote the practice of charitable giving and voluntarism through a variety of strategies including, advocacy, disclosure, information exchange, and research.”1

Foundation/trust/grant-making organization status. Theortically, organizations in this category are not foundations, trusts, or grant-making organizations. However, upon inspection, approximately 4/10 of these organizations are foundations or grant-making organizations, while the remaining 6/10 are not. It is not possible to determine which organizations are public foundations/grant-making organizations without examining each one individually. Therefore, for studies involving public foundations/grant-making organizations, this group warrants close inspection.

Subsector. These organizations can be 501(c)(3) or 501not3 organizations. (See Appendix A for more details about 501(c)(3) vs. 501not3 organizations).

Public or private foundation status. Some of these organizations are public foundations.

(See Appendix A for more details about 501(c)(3) vs. 501not3 organizations).

Values of not PF (private foundation) and not U (unknown) for LEVEL1 indicate that an organization is a not private foundation, and values of T40 or T50 for NTEECC indicate that an organization promotes voluntarism, philanthropy, or charity.

7.3 Private corporate foundation

To qualify as a 501(c)(3) organization, an organization must exist to advance one of the following exempt purposes:

  • Charitable, which includes:

    • “Relief of the poor, the distressed, or the underprivileged;

    • Advancement of religion;

501(c)(3) organizations indicate which exempt purpose(s) they advance when they file Form 1023 or 1023-EZ to apply for recognition of exemption from federal income tax (aka “tax-exempt status”) (Service 2014, 2020).

There are two major tax advantages to having 501(c)(3) status:

  1. 501(c)(3) organizations are exempt from federal income tax; and
  2. They can receive tax-deductible charitable contributions (Service 2018).

501(c)(3) organizations are either public charities or private foundations.

7.19 Appendix B. 501(c)(3) public charities vs. 501(c)(3) private foundations

To qualify as a 501(c)(3) public charity, rather than a 501(c)(3) private foundation, an organization must be one of the following:

  • A church, convention of churches, or association of churches

  • A school

  • A hospital or cooperative hospital service organization

  • A medical research organization operated in conjunction with a hospital

  • An organization operated for the benefit of a college or university that is owned or operated by a governmental unit

  • A federal, state, or local government or governmental unit

  • An organization that normally receives a substantial part of its support from a governmental unit or from the general public

  • A community trust

  • An agricultural research organization operated in conjunction with a land-grant college or university or a non-land-grant college of agriculture

  • An organization that normally receives more than 33 and 1/3% of its support from contributions, membership fees, and gross receipts from activities related to its exempt functions and receives no more than 33 and 1/3 percent of its support from gross investment income and unrelated business taxable income from businesses acquired by the organization after June 30, 1975

  • An organization organized and operated exclusively for testing for public safety

    • Type I – those operated, supervised, or controlled by the supported organization(s) by giving the supported organization(s) the power to regularly appoint or elect a majority of the directors or trustees of the supporting organization

    • Type II – those supervised or controlled in connection with the supported organization(s) by having control or management of the supporting organization vested in the same persons that control or manage the supported organization(s)

    • Type III functionally integrated – those operated in connection with, and functionally integrated with, the supported organization(s)

    • Type III non-functionally integrated – those operated in connection with the supported organization(s) that are not functionally integrated (Service 2022)

501(c)(3) organizations indicate whether they are a public charity or a private foundation when they file Form 1023 or 1023-EZ, and if they are a public charity, they must select the reason they are not a private foundation (Service 2014, 2020). 501(c)(3) public charities also select the reason they are not a private foundation when they file Schedule A (Form 990) every year (Service 2022). Private foundations that later want to be reclassified as public charities must terminate their private foundation status and apply for public charity status.26

The IRS imposes several taxes, restrictions, and requirements on private foundations that it does not place on public charities:

  • Private foundations must pay excise taxes on their net investment income.

  • Private foundations must pay excise taxes on acts of self-dealing with disqualified individuals.

  • Private foundations must distribute a portion of their income annually for charitable purposes.

  • Private foundations must pay excise taxes on any excess holdings above 20% that it and all of its disqualified individuals have in the voting stock of a business enterprise.

  • Private foundations must pay excise taxes on jeopardizing investments (i.e., those that jeopardize the carrying out of exempt purposes).

  • Private foundations must pay excise taxes on expenditures that do not further exempt purposes, such as lobbying.27

Most 501(c)(3) public charities must file an annual Form 990-N, 990-EZ, or 990.28 501(c)(3) private foundations must file an annual Form 990-PF.29
