Nonprofit Filings (IRS 990)

The IRS registry of every e-filed Form 990-series nonprofit return released since 2019 — about 3.5 million filings and growing 400-700K per year. One record per return: EIN, organization name, return type (990, 990-EZ, 990-PF private foundations, 990-T unrelated business income), the tax period covered, and the IRS release year. Phase 1 is the searchable filing registry; financials and officer compensation from the filing XML are a planned phase 2.
