What this data is, and what it is not
  • Source: IRS 990-PF filings, grant schedules, and Business Master File identity data.
  • Privacy: Grant recipients that read as named individuals are withheld unless the IRS Business Master File corroborates an organization of that name in that state. Withheld lines are absent from every count and total on this page..
  • Interpretation: Historical grants do not establish current mission, eligibility, application status, or likelihood of future funding.

An award-line count is the number of individual grant lines reported across covered IRS filings, before the grant search groups lines that share the same recipient, amount, and tax year into a single displayed record.
