1. Introduction – What is Publication 5331?
IRS Publication 5331, titled “Nonprofit Charitable and Other Tax-Exempt Organizations” (Catalog Number 72046Q), is an official report prepared by the Internal Revenue Service Statistics of Income division. It provides a detailed look at the financial health, revenue sources, and annual reporting patterns of the nonprofit world across the United States. Rather than acting as a standard tax instruction booklet, this publication serves as an informative benchmark that reveals how billions of dollars flow through public charities and tax-exempt groups.
Recent IRS catalog reviews in 2026 confirm that the active baseline version of Publication 5331 remains the landmark July revision, officially posted to IRS.gov on July 25. While related tax-exempt and statistical series publications—such as Publication 5332 covering wealthy estate filings—received revisions in July 2026 (posted August 4, 2026), Publication 5331 continues to serve through 2026 as the primary IRS benchmark for measuring the size, scope, and economic footprint of America’s charitable sector.
For everyday readers, Publication 5331 translates complex tax return filings into accessible facts and figures. It sheds light on how charities earn money, where donations go, and how the federal government monitors organizations that operate free from corporate income taxes.
2. Who Should Read This Publication
Publication 5331 is designed for a broad audience that extends well beyond professional certified public accountants. Anyone with an interest in charitable work, philanthropy, or public policy can gain valuable insights from its findings.

3. Key Topics Covered
The publication compiles data submitted on annual information returns to illustrate the economic impact of tax-exempt institutions. It answers fundamental questions about how much wealth the nonprofit sector manages and where that revenue originates.
The table below summarizes the primary areas analyzed within IRS Publication 5331:
| Core Topic | What It Covers | Key Takeaway for Readers |
|---|---|---|
| Sector Composition | Breakdown of 501(c)(3) charities versus other exempt entities | Public charities represent the largest segment of active tax-exempt organizations. |
| Revenue Sources | Program service fees, public gifts, foundation grants, and government funding | Most nonprofit income comes from earned program fees rather than direct donations. |
| Asset Distribution | Comparison of small community nonprofits with large institutional entities | The top tier of institutions holds the vast majority of all charitable assets. |

4. Detailed Breakdown of Main Concepts
The Definition of Tax-Exempt Status
Under Section 501(c)(3) of the Internal Revenue Code, organizations formed for religious, charitable, scientific, literary, or educational purposes can be exempt from federal income taxes. In exchange for this exemption, they must operate exclusively for the public benefit and cannot distribute profits to private shareholders. Publication 5331 illustrates how this special status translates into trillions of dollars in collective community investment.
Program Service Revenue vs. Donations
A surprising finding detailed in the publication is that donations are not the primary source of revenue for the charitable sector as a whole. Nearly 71 percent of all revenue reported by public charities comes from program services. These consist of direct payments for activities fulfilling the organization’s exempt mission, such as patient care charges at nonprofit hospitals, college tuition, and admissions for cultural exhibits.
Gifts, contributions, and government grants make up the second-largest share of sector revenue. While traditional donations remain essential for small charities, larger institutions rely primarily on sustainable service fees to cover operating costs.
The Asset Concentration Gap
Publication 5331 highlights a significant divide between small grassroots organizations and large institutions. Large organizations with assets exceeding $10 million represent less than 10 percent of all filers, yet they account for more than 90 percent of the total assets and revenue in the entire charitable sector. Conversely, small organizations make up the majority of filers but operate with modest cash balances.
5. Practical Examples or Scenarios
Scenario A: The Local Animal Shelter
Consider a small community animal rescue with annual receipts of $35,000. Under IRS reporting rules highlighted in Publication 5331, this organization does not need to complete a comprehensive financial statement. Instead, it submits a simple online electronic notice known as the e-Postcard. This prevents smaller volunteer-run charities from being overwhelmed by complex administrative paperwork.
Scenario B: The Regional Nonprofit Hospital
Now consider a large regional hospital system holding over $500 million in facilities, medical technology, and endowments. This entity generates substantial program service revenue through medical care and files a complete Form 990 with extensive schedules. Publication 5331 demonstrates that institutions like this hospital represent the statistical engine driving overall revenue and asset totals across the nation.
6. How This Publication Relates to Specific Forms
Publication 5331 aggregates information directly from the informational returns filed by tax-exempt organizations each year. Understanding these forms helps clarify where the publication derives its data.
- Form 990 (Return of Organization Exempt From Income Tax): Filed by larger organizations with gross receipts of $200,000 or more, or total assets of $500,000 or more. This form provides the detailed balance sheets and functional expense breakdowns highlighted in the report.
- Form 990-EZ (Short Form Return): A streamlined four-page form used by mid-sized organizations with gross receipts under $200,000 and total assets under $500,000.
- Form 990-N (e-Postcard): An annual electronic notice for small charities that normally receive $50,000 or less in gross receipts. It requires only basic identifying details rather than full financial statements.
- Form 990-T: Used when an exempt organization earns unrelated business income, ensuring taxes are paid on commercial activities unrelated to their core charitable mission.
7. Common Misunderstandings Clarified
Many people assume that “nonprofit” means an organization cannot make money. In reality, tax-exempt entities can generate a financial surplus at the end of the year. The critical rule is that surplus funds must be retained to further the charitable mission rather than distributed as dividends to private owners.
Another common misconception is that all charitable organizations depend mostly on fundraising bake sales or philanthropic galas. As Publication 5331 proves through official filing figures, the vast majority of total charitable revenue is earned through mission-related fees, such as medical services and higher education tuition.
Finally, donors frequently confuse tax-exempt status with donor tax-deductibility. While 501(c)(3) charities allow donors to deduct gifts on their individual tax returns, other exempt organizations—such as 501(c)(4) social welfare groups or 501(c)(6) business leagues—generally do not qualify for deductible charitable contributions.
8. Why This Publication Matters for Taxpayers
Federal tax exemption represents a substantial public investment. Because charities do not pay corporate taxes, and individual donors receive deductions for qualifying contributions, the public relies on transparency to ensure these benefits are justified. Publication 5331 provides this transparency by showing how public resources are put to work across the country.
For community members, understanding this data builds confidence in local charitable programs. It allows donors to see how their favorite causes fit into the wider philanthropic landscape and encourages organizations to maintain responsible governance.
9. Frequently Asked Questions
Does Publication 5331 tell me how to file my annual taxes?
No, Publication 5331 is a statistical and informational reference rather than an instructional filing guide. If you are preparing an annual filing for an exempt organization, you should consult the specific instructions for Form 990, Form 990-EZ, or Form 990-N.
Can I use this publication to research a specific local charity?
Publication 5331 presents aggregated national totals and broad statistical categories rather than individual charity profiles. To inspect a specific organization’s filings, you can use the IRS Tax Exempt Organization Search tool on IRS.gov.
What happens if a charity fails to submit its required annual filing?
Federal law requires the IRS to automatically revoke the tax-exempt status of any organization that fails to submit an annual return or notice for three consecutive years. This rule helps maintain an accurate public register of active, compliant nonprofits.
Why do universities and hospitals dominate the publication’s asset figures?
Colleges and hospitals require significant physical infrastructure, expensive equipment, and long-term financial endowments to operate. As a result, their balance sheets naturally reflect far higher asset values than community youth groups or small rescue missions.
10. Conclusion
IRS Publication 5331 offers a fascinating look into the financial scale and diversity of the American nonprofit sector. By organizing complex filing data into clear summaries, it demonstrates how organizations balance earned program income, government grants, and community contributions. Whether you manage a charity, donate to meaningful causes, or simply want to learn how tax-exempt rules function in practice, this publication provides a valuable window into the philanthropic economy.
