Trace Nonprofits: Follow the Money Between Nonprofits

Field notes

Trace Nonprofits combines IRS Form 990 filings, the Exempt Organizations Business Master File, and Single Audit results into linked organization records. Its stated coverage is two million US nonprofits, with filters for cause, revenue, state, and data quality, plus CSV export. Grant recipients and funders can be followed in both directions, while shared-name matches remain leads for checking rather than asserted relationships. The homepage also states that new IRS and federal audit data is loaded monthly.
