A Complete List of Types of Nonprofits : Which One Should You Start?

Ask one hundred people what a nonprofit is, and you will get one hundred different answers. This confusion may be because of the variety of types of nonprofits.  And the name nonprofit itself can be confusing. While most people assume a nonprofit to be a charitable organization, many different types of organizations are classified under this title. The detailed list in this blog will give you a better idea of where your organization can fit and what federal benefits you can receive.

Before we begin, let us explain what a nonprofit is and as per the IRS, how it must operate.

What is a Nonprofit?

A nonprofit is a legal entity that is created and operated for a collective, public, or social benefit.

There is a common misconception that nonprofits do not make money. This is an understandable assumption based on the name, but the reality is a bit different. Many nonprofits make quite a bit of money and are big businesses. In fact, nonprofits are America’s third-largest employer.

Nonprofits include more than the homeless shelter or food pantry down the street; it also includes your nearest hospital, church, library, and Chamber of Commerce, to name only a few. According to the Internal Revenue Service (IRS), there are 27 different types of 501(c) and 5 other types of organizations. These organizations are exempt from federal income taxes and have a significant impact on your community.

The one rule that all nonprofit organizations must follow to remain tax-exempt is not paying out profits. The IRS states that “no part of the organization’s net earnings can benefit any private shareholder or individual.” This means no shareholders that can get rich from the organization.

In some states, nonprofits are allowed shareholders, but these individuals do not take a salary. Instead, they are often organization founders who hold onto control over the organization through their shares and voting power.

32 Different Types of Nonprofit Organizations

Now that we have cleared up what a nonprofit is, we can move on to the list of nonprofit types. The IRS has granted federal tax exemption to a variety of nonprofits. These organizations range from public charities and private foundations to trade associations and pension funds.

The IRS publication 557 provides details on each of these categories.

1. 501(c)1 – Corporations organized under acts of Congress

Federal credit unions are the best example of this type of organization. A 501(c)1 organization is not required to apply for tax-exempt status or fill out annual tax returns because they were organized by Congress. Those making contributions to this type of nonprofit can get tax breaks as long as their donation is exclusively for public purposes.

2. 501(c)2 – Titleholders for single parent corporations

This type of 501c only qualifies for a tax exemption through its connection with other tax-exempt organizations. An owner of a title-holding corporation must turn over the entire income of the property, minus expenses, to one or more tax-exempt organizations.

3. 501(c)3 – Religious, charitable, scientific, testing for public safety, literary, educational, fostering national or international amateur sports competitions, preventing cruelty to children or animals

501(c)3 is the most popular nonprofit type. These nonprofits are either public charities or private foundations and must apply for tax-exempt status with the IRS and their home state. These organizations also must file 990 tax returns every year. Those that fail to file for over three years will be in danger of losing tax-exempt status.

If you are interested in starting a 501(c)3 organization, you should also check out the 501c3 donation rules beforehand.

Examples of well-known 501(c)3 nonprofits include Habitat for Humanity, Make-a-Wish Foundation, Nomi Network, Healthcare for the Homeless, Word on Fire Catholic Ministries, Voices of Our City Choir, and so many more.

Here’s a glimpse into Voices of Our City Choir‘s website donation page using the embeddable Donorbox recurring donation form to accept donations.

501(c)3 organizations must operate as a corporation and are further broken down into the following:

3.1 509(a)1 – Public supported charity

To qualify as a publicly funded 509 (a)1 charity, the organization will generally pass the one-third support test.

Organizations pass the one-third support test if over five years, at least one-third of their total support comes from public sources like gifts, grants, and other public contributions. Examples of this type of organization are schools, churches, and hospitals.

3.2 509(a)2 – Exempt purpose activity-supported charities

Under this section, organizations that qualify for 509(a)2 tax-exempt status receive funds from gifts, grants, contributions, and fees for their service. An example of this type of organization is a therapy center that provides services to the community and raises funds through events and fundraising campaigns.

3.3 509(a)3 – Supporting organizations for 509(a)1 and 2 charities

While 509(a)3 is not a public charity, it is tied to nonprofits that are. Foundations for universities, hospitals, libraries, fire departments, and police stations can gain tax-exempt status under this section.

3.4 509(a)4 – Public safety charities

509(a)4 public safety charities are not foundations or public charities. There are no public support requirements for this type of organization. Instead, they must meet the tests required for public testing.

3.5 Private foundations

Private foundations may not fit any of the above qualifications but can gain tax-exempt status through this section. Private foundations usually rely on one source of income, commonly an endowment or fund. These organizations must focus on giving grants to other public charities.

4. 501(c)4 – Civic Leagues and Social Welfare Organizations

501(c)4 organizations concentrate on social welfare. The members of these organizations must be in one location, work for the same employer, or have a similar connection. Net earnings of these organizations must also be for charitable, educational, or recreational purposes.

Many Super PACs qualify for tax-exempt status under this section of the tax code. These groups can remain tax-exempt through their goals of “educating the population on specific social welfare issues.” The National Rifle Association (NRA) is organized as a 501(c)4.

501(c)4 organizations do not have to disclose their donor list. This has made 501(c)4 status very popular.

527 Political organizations

Some may wonder why the IRS has two separate sections for political organizations. The difference between the two is mainly in what they must report.

527 organizations are parties, committees, funds, or associations created to accept donations directly or indirectly. They can raise unlimited amounts but cannot influence the election of candidates. They also must disclose donor names.

Here’s an example of a noteworthy 501c4 organization, Battle Born Moms for Education that raises money to fight for their parental rights, for education, and fair representation in Nevada’s Washoe County School District.

5. 501(c)5 – Labor, agricultural and horticultural organizations

501c(c)5 qualifies for both labor and agricultural organizations with tax-exempt status. Labor organizations must promote their members’ interests through collective bargaining with their employers to gain this status.

Agricultural and horticultural organizations must work with animal or vegetable life, not minerals. Their primary purpose must also be to better the conditions of those working in these areas, develop more efficiency, or improve their products.

A few examples of this type of organization are groups that exhibit livestock or farm products, organizations that test soil for farm bureau members, and associations that negotiate crop prices.

6. 501(c)6 – Business leagues

Chamber of Commerce, Board of Trade, Real Estate Boards, and Professional Football Leagues are all tax-exempt under the 501(c)6 section of the tax code. These organizations are either located in the same city or are engaged in a similar line of business. They also must focus on business improvements.

A great example of 501cc6 would be The American Solar Grazing Association (ASGA). Here’s a snapshot of their donation page hosted by Donorbox for free.

7. 501(c)7 – Social and recreation clubs

College fraternities, sororities, country clubs, amateur hunting, fishing, tennis, swimming, and dinner clubs all qualify for the 501(c)7 tax-exempt status.

Because of this status, several regulations must be followed:

  • Discrimination is prohibited.
  • Members must be bound together by a common objective of pleasure, recreation, etc.
  • Social clubs must have limited membership.
  • Clubs can only be funded by membership fees, dues, and assessments.
  • Clubs cannot sell real estate, products, or services.

Notable examples of 501c7 include The Rolla Alumni Chapter of Beta Sigma Psi, OX Epsilon Chapter, etc.

8. 501(c)8 – Fraternal beneficiary societies

Fraternal societies like the Elks Lodge, Knights of Columbus, and Freemasons have been around for centuries. These organizations can only collect tax-deductible gifts if they are for charitable purposes. Under 501(c)8 section of the tax code, these societies can pay life, sick, accident, and other benefits for their members and their dependents.

9. 501(c)9 – Voluntary Employees’ Beneficiary Associations (VEBA)

VEBA are groups of employees who donate for other employee’s life, sick, accident, and other benefits. These organizations must be connected through employment or membership in a labor union, and the purpose must be only to provide benefits.

Restrictions for these organizations include a non-discrimination requirement. Higher-paid employees cannot benefit more than the rest.

10. 501(c)10 – Fraternal societies

In addition to providing benefits for their own members, fraternal societies have a history of collecting donations to support others in their community and worldwide. Through section 501(c)10, domestic societies can collect funds to support religious, charitable, scientific, literary, educational, and fraternal goals.

The IRS created 501(c)10 as a separate category from 501(c)8 for fraternal societies that do not provide insurance for their members. The Masons are an excellent example of an organization that solely collects funds for charitable purposes.

11. 501(c)11 – Teacher’s retirement fund associations

Teacher’s retirement fund associations are organized locally and pay retirement benefits for teachers and other school employees. These organizations are funded through taxes, member donations, and investment revenue.

12. 501(c)12 – Local benevolent life insurance associations, mutual irrigation, telephone companies, and like organizations

The goal of this tax exemption is to provide services to members at the lowest possible cost. These organizations must collect at least 85% of their income from their members.

13. 501(c)13 – Cemetery companies

501(c)13 cemetery companies are also tax-exempt under the Internal Revenue Code. These companies can remain tax-exempt while paying operating and maintenance costs. They can also spend funds on cemetery or crematorium improvements and new property.

Here’s an example of a 501c13 organization using the Donorbox recurring donation form to accept donations for their cemetery support.

14. 501(c)14 – State-chartered credit unions and other mutual financial organizations

Credit unions are tax-exempt from federal income taxes under 501(c)14. These organizations receive tax-exempt status because they benefit their members and serve as sources of credit for a low- and moderate-income population.

15. 501(c)15 – Mutual insurance companies or associations

Small insurance companies can also gain tax-exempt status with 501(c)15. These companies are usually based in small communities and are mutually beneficial. These organizations provide insurance to members at cost and offer necessary services like property damage, burial, and funeral benefits.

16. 501(c)16 – Cooperative organization to finance crop operations

Farmers’ cooperative marketing or purchasing associations can claim tax exemption if they are in conjunction with the farmers’ cooperative association. The activities covered under 501(c)16 include the funding of farm equipment, crop cultivation, livestock, warehouse, shipping, and marketing.

17. 501(c)17 – Unemployment benefit trusts

A supplemental unemployment benefit trust can be tax-exempt if it exists solely to pay for supplemental compensation benefits and does not discriminate. This tax exemption must be applied for with 1024 applications, and contributions are not tax-deductible.

18. 501(c)18 – Employee funded pension trust

Pension trusts created before June 25, 1959, are tax-deductible under this statute. They cover benefit payments for unemployed members. These pension trusts are fully funded by employees.

19. 501(c)19 – Veterans’ organizations

All veterans’ organizations organized in the United States are tax-exempt under 501(c)19. These organizations assist disabled and need vets, create remembrance programs, provide insurance for members, sponsor patriotic activities, and provide social and recreational activities.

To remain tax-exempt, at least 75% of the organization’s members must be past or present members of the armed forces.

20. 501(c)21 – Black lung benefit trusts

The Federal Black Lung Benefit Act was passed by Congress in 1969. It forced coal mine operators to pay benefits to miners who suffered from the disease because of long-term exposure to coal dust. In 1977, Congress amended the code to create a trust fund for these benefits. These trusts are funded by coal mine operators and pay premiums for insurance, accident and health benefits for coal miners and their spouses, and administrative and incidental expenses.

21. 501(c)22 – Withdrawal liability payment fund

This tax exemption was created to provide funds to meet employers’ liability withdrawing from a multi-employer pension fund.

22. 501(c)23 – Veterans’ organizations (before 1880)

Veterans’ organizations created before 1880 are tax-exempt under 501(c)23. 75% of members must be past or present members of the armed services.

23. 501(c)25 – Title-holding corporations or trusts for multiple parent corporations

This type of nonprofit must be a corporation or trust. They are to exclusively acquire, hold title to, and collect income from real property. They must turn over the entire amount, minus expenses, to tax-exempt organizations. Unlike title holders for single-parent corporations, these companies can have up to 35 shareholders or beneficiaries.

24. 501(c)26 – State-sponsored high-risk health coverage organizations

These membership organizations must be established by the state and provide care to high-risk individuals. They will either issue insurance or enter arrangements with HMOs to provide service.

25. 501(c)27 – Qualified state-sponsored workers’ compensation organizations

This tax exemption splits organizations into two groups.

25.1 501(c)27(a)

This section provides tax exemption to organizations formed before June 1996. These nonprofits also exclusively reimburse their members. These members are all individuals and government entities who issue insurance or self-insure against workers’ compensation losses.

25.2 501(c)27(b)

The second group consists of organizations formed after December 1997. These organizations are created by state law and provide workers’ compensation.

26. 501(c)28 – National railroad retirement investment trust

The Railroad Retirement and Survivor’s Improvement Act of 2001 created this organization to manage and invest the railroad retirement account assets. The purpose of this act was to diversify these investments.

27. 501(c)29 – Co-op health insurance issuers

As part of the Affordable Care Act, all qualified nonprofit health insurance issuers who received a loan or grant under the medicare and Medicaid services co-op program are tax exempt.

28. 501(d) – Religious and apostolic associations

This tax exemption was initially for the shakers and similar religious groups. These groups must share all income in a community account. These associations are often farming or manufacturing communities. The community owns all property.

29. 501(e) – Cooperative hospital service organizations

These cooperatives perform data processing, purchasing, warehousing, billing, collection, food, clinical, industrial engineering, laboratory, printing, communications, record center, and personnel services for hospitals. Organizations qualify for this tax exemption if they provide these services to two or more tax-exempt hospitals.

30. 501(f) – Cooperative service organizations of operating educational organizations

Cooperatives are tax-exempt if they invest the money pooled from members of operating educational organizations and return the income to said members.

31. 501(k) – Child care organizations

In 1984, Congress added a section to the Internal Revenue Code to include certain child-care organizations as tax-exempt. These organizations gain tax exemption by allowing parents of children the opportunity for “gainful employment.” At least 85% of the services provided should be for working parents in the general population, not for specific employers.

32. 501(n) – Charitable risk pools

Charitable risk pools combine certain insurance risks, other than medical malpractice, of 501(c)3 organizations. They must also provide information on loss control and risk management. All members of these pools must be tax-exempt.


We hope that these types will help you determine which type of nonprofit yours will be.

Please note that nonprofits can raise funds through membership dues, grants, charitable gifts, investments, and more. The only common denominator is that all nonprofit organizations must reinvest their income back into the organization.
