What Is IRS Form 990? The Public Return Behind Nonprofit Pay Data

IRS Form 990 is the annual information return that most tax-exempt organizations must file under Internal Revenue Code §6033. It is not a tax return in the ordinary sense — most filers owe no tax — it is a public accountability document: finances, governance, programs, and the compensation of the organization's leaders, refiled every year and, under IRC §6104, open to public inspection. It is the reason nonprofit executive pay is public information.

Which version an organization files

• Form 990-N ("e-Postcard") — organizations whose annual gross receipts are normally $50,000 or less. Eight questions, no financial detail.
• Form 990-EZ — gross receipts under $200,000 and total assets under $500,000 at year end.
• Form 990 — everyone larger. This is the full return, with the compensation detail in Part VII and, for higher-paid leaders, Schedule J.
• Form 990-PF — private foundations, regardless of size.

Churches and certain church-affiliated organizations are generally not required to file (IRC §6033(a)(3)), which is why some large religious organizations have no public 990 at all.

When it is filed — and why the data lags

The return is due the 15th day of the 5th month after the organization's fiscal year ends — May 15 for calendar-year filers — and a six-month extension (Form 8868) is routine. A fiscal year ending June 30, 2025 can therefore be legitimately filed as late as May 2026, and appear in public datasets later still. This filing lag is why the most recent year in any 990-derived dataset is always incomplete, and why serious benchmarking states a span of filing years rather than pretending to a single current year.

What happens if an organization doesn't file

An organization that fails to file for three consecutive years automatically loses its tax-exempt status by operation of law (IRC §6033(j)) — no IRS discretion involved.

Where the compensation data lives

Part VII lists the organization's officers, directors, trustees, key employees, and its five highest-compensated employees over $100,000, with their reportable compensation. How to read those sections without being misled is its own skill, and Schedule J breaks the bigger numbers into base, bonus, deferred and benefits. CauseComp's published salary benchmarks and executive benchmarking tool are built from these filings — disclosed figures from returns the organizations themselves signed, not survey responses.
