NFP500 U.S. Non-Profit Rankings
NFP500 · Rankings · Fiscal Year 2023

The largest U.S. non-profits, by the numbers

A public record assembled entirely from IRS Form 990 filings — ranked by revenue and opened up so you can interrogate what the money actually says about the organisations that serve the public good.

Scope. Hospitals, health systems and universities are excluded — they would otherwise fill most of the top ranks. What remains is the rest of the field: foundations, donor funds, charities, health plans, member & benefit funds and research institutes. A further six large filers were set aside for insufficient public documentation and replaced by the next-largest well-documented organisations, keeping the register at 500.

06Methodology

How this was built

Sources

The ranking is drawn from the IRS Statistics of Income Form 990 and 990-PF master extracts (processing year 2024, covering tax years mostly ending in 2023), joined to the IRS Exempt Organizations Business Master File for each organisation's name, cause area and year of recognition. Descriptions and mission statements were researched from each organisation's own public sources.

What "revenue" means

Organisations are ranked by total revenue as reported on the return — contributions, programme-service revenue, investment income and other receipts combined. Year-on-year change compares each filer with its own prior-year return.

Exclusions

Hospitals, health systems and their affiliated physician groups, together with degree-granting universities and colleges, are removed — they would otherwise occupy most of the leading positions and crowd out the wider sector. Government bodies, most churches and certain mutual insurers do not file a Form 990 and cannot appear.

Limitations

These are financial filings, not a verdict. The 990 master file does not carry the programme-versus-overhead expense split, and no financial line can measure mission impact. Large groups may file several returns; each row reflects a single filing entity. Treat the figures as a starting point for questions, not a final grade.

07About

About NFP500

NFP500 is an independent research project that turns the United States' public non-profit filings into something you can actually read and question. It exists on the principle that money spent in the name of the public good should be legible to the public — clearly ranked, plainly described, and open to scrutiny rather than taken on trust.

Everything here traces back to a filed, public document. Nothing is for sale, and no organisation has paid to appear or to be described a particular way. Where a figure is missing or a mission statement could not be verified, that gap is shown honestly rather than filled.
