What is a Form 990?

Form 990 is the IRS annual information return most tax-exempt organizations file to report mission, governance, revenue, expenses, compensation, and public-support details. It is not an income-tax return in the ordinary business sense; it is a public accountability filing used to look up nonprofit finances and community-benefit disclosures.

Full name: IRS Return of Organization Exempt From Income Tax

Short explanation

IRS Form 990 is filed by many tax-exempt organizations, including charities, foundations, and tax-exempt hospitals. The core form reports organizational identity, program service accomplishments, revenue, expenses, officers, compensation, and governance practices. Schedules add detail for specific categories, such as Schedule H for nonprofit hospitals' community-benefit reporting. Analysts use it as one public record in a broader diligence file.

Last updated: 2026-07-11Reviewed by: Fonteum data standards desk — Source-provenance editorial review. Definitions checked against primary federal sources.

How it’s used

  • Nonprofit lookup: Form 990 lets researchers inspect a tax-exempt organization's revenue, expenses, compensation, grants, and related-party disclosures.
  • Hospital community benefit: nonprofit hospitals report Schedule H detail that complements CMS HCRIS charity-care and bad-debt cost-report fields.
  • Fonteum links Form 990 concepts to source-provenanced organization records, treating the filing as one public-source layer rather than a standalone judgment.

Frequently asked questions

Who files Form 990?
Many tax-exempt organizations file Form 990 annually, though filing requirements and shorter variants depend on organization type, gross receipts, and assets.
Is Form 990 public?
Yes. Form 990 is generally a public information return, which is why researchers and donors use it to look up nonprofit finances and governance disclosures.
How is Form 990 different from Schedule H?
Schedule H is an attachment to Form 990 used by tax-exempt hospitals to report community-benefit activities, financial assistance, and related policies.

Reproducible by design

Published figures name their source and date.

Source and date

Published research identifies its government file and observation date. Source-file SHA-256 coverage is disclosed separately; facts do not currently link deterministically to signatures.

Reproducible SQL

Each study ships the exact query behind its figures, run against the same dated copy of the federal file we used. Re-run it yourself.

Daily observations

The platform records table row counts daily. Those observations detect local drift; they do not imply that an upstream publisher released or Fonteum ingested new data that day.
