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.

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.

Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.

Source authority is record-specific

Use the issuer named on the record.

Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.

Source and date

Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.

Available derivation

Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.

Daily observations

Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
