How to Read a Local Nonprofit’s Form 990

City-level pages aggregate organizations whose principal office is in Washington. That includes locally founded charities, regional affiliates that file independently, and national organizations whose headquarters happen to sit here. Reading any one organization’s 990 starts with Part I (summary), then Part VIII (revenue), Part IX (functional expenses, where the program ratio comes from), and Part VII / Schedule J (compensation).

The NonprofitTruth Efficiency Score is a 0–100 composite that summarizes four signals from the Form 990: program-spending ratio (50% of the score), revenue-growth consistency over multiple years (20%), months of fund reserves on the balance sheet (20%), and CEO compensation as a share of revenue (10%). The grade A–F mapping is purely descriptive — it summarizes the financial structure that the 990 reveals, not the social impact, program quality, or outcomes of the work the organization does. Donors evaluating impact should pair these financial signals with program-level evaluations from sources like Charity Navigator, GiveWell, or the organization's own audited reports.

Many smaller Washington organizations file the abbreviated Form 990-EZ. The EZ form does not require the same level of compensation detail as the full 990, so the CEO-pay column may be blank for some entries even when the organization has paid leadership.

Source Data and Verification

All financials on this page come from each organization's IRS Form 990 — the federal information return that 501(c)(3) public charities, private foundations, and most other tax-exempt organizations must file annually. The Form 990 is a public document. We ingest it primarily through the ProPublica Nonprofit Explorer feed, which mirrors the IRS Tax-Exempt Organization Search dataset. Original e-file XML and PDF copies of any return can be looked up directly at the IRS, ProPublica, or the Candid (formerly GuideStar) directory.

For every Washington organization listed above, the underlying Form 990 is available free of charge from the IRS Tax Exempt Organization Search, the ProPublica Nonprofit Explorer, or the Candid (GuideStar) directory.
