# IRS Form 990 Explained: Which 990 Your Nonprofit Files and When

*Published 2026-07-07*

**Direct answer:** Form 990 is the annual public information return tax-exempt organizations file with the IRS: organizations with gross receipts normally $50,000 or less file the Form 990-N postcard, mid-sized organizations file Form 990-EZ, larger organizations file the full Form 990, and every private foundation files Form 990-PF.

> The Form 990 series is the annual information return nearly every exempt organization files. Here is which version applies to you and why missing it is costly.

Form 990 is the annual information return that tax-exempt organizations file with the IRS. It is not a tax return in the ordinary sense, since exempt organizations generally owe no income tax on mission revenue; it is a public disclosure document reporting the organization's finances, governance, programs, and compensation. Donors, journalists, and regulators read 990s, and charity databases republish them, so the 990 doubles as the organization's public financial face.

The four versions

Which form you file depends on size and classification. Form 990-N, the electronic postcard, covers small organizations with gross receipts normally $50,000 or less; it asks only a handful of identifying questions. Form 990-EZ is the short form for mid-sized organizations under thresholds for gross receipts and total assets. The full Form 990 is the long-form return for larger organizations, with schedules covering fundraising, foreign activity, related organizations, and executive compensation. Form 990-PF is the separate return every private foundation files regardless of size, reflecting the payout and excise tax rules covered in our post on foundations vs public charities. Churches are generally not required to file at all, one of the distinctions explained in our post on whether churches are nonprofits.

Deadlines and the three-year rule

The return is due on the 15th day of the fifth month after the fiscal year ends, May 15 for calendar-year organizations, with a six-month extension available on Form 8868. The consequence that matters most: an organization that fails to file for three consecutive years has its exempt status automatically revoked by operation of law. Reinstatement requires a new application and often a reasonable-cause showing, and donations made during the gap may not be deductible.

The 990 feeds your state filings

The 990 is also the backbone of the state compliance calendar. Most of the roughly 40 states that require charitable solicitation registration ask for the most recent 990 with every annual renewal, and several key their renewal deadlines to your 990 timing; states above certain revenue thresholds add reviewed or audited financials on top. That is why we treat the 990 and the registration renewals as one program in our nonprofit licensing practice, with each state's renewal requirements mapped in the charitable registration hub. New organizations should calendar the first 990 at formation; the full startup sequence is in our guide on how to start a nonprofit.
