In this article, you can find detailed information about 501(c)(3) public charities and their tax filing requirements.

How does the IRS define Public Charities?

Public charities are organizations that operate towards furthering any exempt purposes and have obtained tax-exempt status from the IRS under section 501(c)(3).

Generally, the IRS classifies the following organizations as public charities,

Churches, Hospitals, Qualified medical research organizations affiliated with hospitals, Schools, Colleges, and Universities

Organizations that have an active program of fundraising and receive contributions from various sources such as the general public, governmental agencies, corporations, private foundations or other public charities

Organizations that generate income by conducting activities that further the organization’s
exempt purposes

Organizations that are involved in a supporting relationship to one or more existing public charities.
