What is a Form 990?
IRS Form 990 is the annual information return that tax-exempt organizations file with the federal government. It discloses revenue, expenses, officer compensation, grants, and governance.
What is a Form 990-PF?
Form 990-PF is filed specifically by private foundations — organizations funded by a single source (individual, family, or corporation). Includes grant recipient lists and distribution requirements.
Why does this matter?
Nonprofits manage over $4 trillion in assets in the US. Their filings are public record — this tool transforms raw IRS data into interactive visualizations.
Who is this useful for?
Donors researching where to give. Grant seekers identifying funders. Journalists investigating finances. Analysts studying philanthropic trends.
What can you explore?
For 990-PF: grant treemaps, distribution analysis, officer compensation. For regular 990: functional expenses, revenue DNA, governance scorecards.
