Are Public Libraries Considered Nonprofit Organizations?

Estimated reading time: 12 minute(s)

Public libraries are often associated with charitable work, community service, and education. Because of this, many people assume that public libraries operate as nonprofit organizations.

However, from a legal and tax perspective, the situation is slightly different. Most public libraries in the United States are not classified as nonprofit organizations under IRS rules. Instead, they typically operate as government entities, usually managed by a city, county, or state government.

Understanding this distinction is important, especially when it comes to tax status, donations, and grant eligibility.

Tax-Exempt Status for Public Libraries

In general, public libraries do not receive 501(c)(3) exemption status from the IRS; however, they are still considered tax-exempt organizations. 

Under IRS rules, state and local governments are automatically exempt from federal income tax because they are governmental units. Since most public libraries operate under a municipal or state government structure, they receive the same tax-exempt treatment.

This means public libraries typically do not need to apply for tax-exempt recognition the way charitable nonprofits do.

Proof of Tax-Exempt Status for Grants

When applying for grants from foundations or charitable organizations, public libraries may still need to provide documentation confirming their tax-exempt status.

Libraries can usually verify their status by providing:

• Their Employer Identification Number (EIN)
• A Governmental Information Letter issued by the IRS

The letter also explains how the entity is applicable for deductible contributions and income exclusion.

Can a Library Become a 501(c)(3) Organization?

When a new public library gets commissioned by an administration of public education, it is automatically exempt from state taxes and typically doesn’t pay federal taxes because of its governing entity status. In particular circumstances, a library can request to qualify as a 501(c)(3) organization instead of a government entity.

To do this, the library must file Form 1023. Once approved, the library would be treated as a 501(c)(3) charitable organization instead of a governmental unit.

However, this structure is less common than the traditional government-operated public library model.

The Role of Library Foundations and “Friends of the Library” Groups

While operating as a government entity, libraries can enlist another 501(c)(3) organization to accept funds or donations on their behalf – these nonprofit organizations are typically friend groups, community foundations, or library associations. They use public contributions and grants towards charity, education, the promotion of literature, and related administrative costs. 

Among other activities, these exempt organizations’ charitable efforts are for improving public libraries, promoting literacy, and awarding scholarships.

Because these organizations are nonprofits, they must comply with IRS filing requirements.

Tax Deductible Contributions

Public libraries and their associations are eligible to receive tax-deductible charitable contributions. The IRS requires a receipt for donors who contribute over $250. You can give receipts or a “thank you” for lesser amounts if you choose, but the primary reason is for those planning to deduct their donation from their tax bill.

The tax receipt should contain the following information:

• Name and address of the organization
• Date the contribution was given
• The amount of a cash contribution or the description of a non-cash donation
• A statement of goods or services that are given in return for the contribution, if necessary

If there’s a donor who gives numerous small donations throughout the year, and their total amount is over $250, they will also need a written receipt for tax purposes. 501(c)(3) organizations or associations that are accepting contributions on behalf of a library will need to report individual donations of $5,000 or greater on Schedule B of their Form 990.
