Introduction
Starting a nonprofit is an inspiring step toward lasting impact—but the type of nonprofit you choose shapes how your organization operates. Most nonprofits recognized under 501(c)(3) fall into one of two categories: public charities or private foundations.
Understanding the difference between the two will help you choose the right fit for your mission, funding model, and compliance requirements.

What Is a Public Charity?
A public charity is a nonprofit that provides programs or services directly to the public. Examples include food banks, educational programs, disaster relief efforts, and community health clinics.
Public charities:
- Receive most of their funding from the general public, grants, or government sources
- Must meet the IRS "public support test" to maintain their status
- Typically file IRS Form 990 each year to report income and activities
Because they rely on public donations, public charities often focus on visibility, storytelling, and trust to sustain support.
What Is a Private Foundation?
A private foundation is a charitable organization funded primarily by one source, such as an individual, family, or corporation. Foundations usually support charitable causes through grants or investments rather than running public programs.
Private foundations:
- Are subject to more regulations under the Internal Revenue Code
- File IRS Form 990-PF each year
- Must distribute at least 5 percent of their assets annually for charitable purposes
- Are closely governed, often by the founder or family members
While foundations have greater control over their funds, they carry higher administrative and reporting responsibilities.
Key Differences Between Public Charities and Private Foundations
Understanding these structural differences can help you choose the right path for your nonprofit's goals.
- Funding sources: Public charities raise funds from the general public; private foundations are funded by a single source or endowment.
- Operation: Public charities run programs or provide services directly; private foundations mainly fund other organizations.
- Governance: Public charities maintain broad, diverse boards; private foundations are often led by smaller family or corporate boards.
- IRS rules: Private foundations face excise taxes and annual payout requirements; public charities meet public-support tests instead.
- Transparency: Public charities must demonstrate community accountability; foundations must disclose investment income and grants.
