A Complete Resource for Nonprofit Leaders and Fundraisers
The data is public.
The insight isn't.
Every tax-exempt organization in America files one — or a variation of one. Public charities file the full 990, private foundations the 990-PF, and the smallest nonprofits a postcard. Most people treat it as a compliance chore. It is the most revealing public document in the nonprofit sector — a window into how an organization raises money, spends it, pays its people, and survives the year. (The official form and filing instructions are on the IRS’s Form 990 page.)
For a fundraiser, a 990 is a prospect-research tool hiding in plain sight. For a board member, it is the scorecard the public sees. For a small nonprofit leader filing one, it is the difference between looking healthy and looking like a risk. Same form, three readers, one shared truth: the numbers talk.
This resource center is built for the people who read 990s, not just the ones who file them. No tax-prep boilerplate. No IRS jargon recycled into a blog post. Just how to read one properly.
BEYOND THE NUMBERS
The filing may be complete, accurate and perfectly legal. But what does it communicate to donors, board members, journalists and prospective employees? Explore The Public Record, our editorial series about what nonprofit filings reveal, what they miss and how organizations appear from the outside.

990 Schedules Explained
Schedule A, B, D, G, I, O and the rest — what each one is and what it reveals.
What is Form 990?
It’s the annual information return most tax-exempt organizations file with the IRS, disclosing finances, governance, and compensation.
Are Form 990 filings public?
Yes. By law, 990s are open to public inspection, which is what makes them useful for research.
Is it safe to publish our EIN on our website?
Yes. It’s already public — on your 990, in the IRS database, and on this site. Withholding it mostly costs you gifts, since DAF grants and beneficiary designations need it. Complete details here.
What’s the difference between the 990, 990-EZ, 990-N, and 990-PF?
They’re sized to the organization. Larger nonprofits file the full 990, smaller ones the 990-EZ or the 990-N postcard, and private foundations file the 990-PF.
How current is 990 data?
There’s usually a lag of a year or more between an organization’s fiscal year-end and its filing appearing publicly.
Can I see executive salaries on a 990?
Yes. Reportable compensation for officers, directors, trustees, and key employees is disclosed.
Where do I find a specific nonprofit’s 990?
Several public sources carry them. The Where to Find 990 Filings page covers each one.
