Understanding the Different 501(c) Categories

5 min read · Last reviewed October 2026

Section 501(c) of the Internal Revenue Code lists more than two dozen kinds of tax-exempt organizations. Most organizations fit one of these:

Public charity or private foundation?

Every 501(c)(3) is presumed to be a private foundation unless it shows it qualifies as a public charity — usually by receiving broad public support, or by being a church, school, hospital, or supporting organization. Private foundations face stricter rules, including excise taxes on investment income, minimum annual payouts, and limits on dealings with insiders.

Picking the right category

Your category depends on your purpose and who benefits — not on what you'd prefer for tax reasons. If your organization serves members rather than the public, it probably isn't a 501(c)(3).
