The 4 Types of Form 990: 990, 990-EZ, 990-PF, 990-N Explained

The Form 990 series is the IRS's primary tool for oversight of tax-exempt organizations. Each year, nonprofits must file one of four variants depending on their organizational type, gross receipts, and total assets. The information disclosed on these forms — from executive compensation to program expenses to grant distributions — is publicly available and used by donors, journalists, regulators, and watchdog organizations to evaluate nonprofits [1].

Choosing the correct form matters. Filing the wrong variant can result in penalties, rejected filings, or gaps in public disclosure. And failing to file at all — even the simplest e-Postcard — can lead to automatic revocation of tax-exempt status after three consecutive years [2].

The full Form 990 is required for tax-exempt organizations with gross receipts of $200,000 or more, OR total assets of $500,000 or more [3]. It is the most comprehensive of the four variants — the core form runs 12 parts and may require up to 16 additional schedules depending on the organization's activities.

Certain organizations must file the full 990 regardless of size: sponsoring organizations of donor-advised funds, organizations operating hospital facilities, Section 501(c)(29) nonprofit health insurance issuers, and organizations filing group returns [3].

Form 990-EZ is a shorter version of the full 990, available to organizations with gross receipts less than $200,000 AND total assets less than $500,000 [4]. Both thresholds must be met — an organization with $150,000 in gross receipts but $600,000 in total assets must file the full 990.

The 990-EZ provides less financial detail than the full 990. It does not include a functional expense statement (the breakdown of program vs. administrative vs. fundraising expenses), and compensation reporting is limited to officers and directors. For donors and researchers, this means less granular data for evaluating a nonprofit's overhead ratio or benchmarking executive compensation.

Form 990-PF (Return of Private Foundation) is filed by all private foundations and Section 4947(a)(1) nonexempt charitable trusts, regardless of their financial size [5]. There is no revenue or asset threshold — even a foundation with $1,000 in assets must file the full 990-PF.

The 990-PF is particularly valuable for grant research. RoundPaper's database includes 8.6 million+ grant records extracted from 990-PF filings. You can search for any foundation to see their grant history, giving patterns, and total distributions.

Form 990-N, commonly called the e-Postcard, is available to tax-exempt organizations whose gross receipts are normally $50,000 or less [7]. It is filed electronically only — no paper version exists — and collects just eight pieces of information.

The "normally" threshold is calculated differently based on organizational age: organizations less than one year old qualify if they received or were pledged $75,000 or less; organizations 1-3 years old qualify if they averaged $60,000 or less; and organizations three or more years old qualify if they averaged $50,000 or less over the prior three years [7].

RoundPaper's database includes 1.5 million+ e-Postcard records. While the 990-N reveals minimal financial information, it confirms that an organization is still active and maintaining its tax-exempt status.

The table below summarizes the key differences across all four form types. The most important distinctions are filing thresholds, the level of financial detail disclosed, and whether donor information is publicly available.

The IRS uses gross receipts and total assets to determine which form an organization must file. These thresholds have remained stable since 2010, when the 990-EZ limits were raised from $100,000/$250,000 to the current $200,000/$500,000 and the 990-N threshold was increased from $25,000 to $50,000 [4] [7].

Organizations can always file a more detailed form than required. A small nonprofit eligible for the 990-N can voluntarily file the 990-EZ or full 990 — this can be useful for transparency or when applying for grants that require detailed financials.

While most tax-exempt organizations must file some version of the 990, the IRS exempts several categories from all annual filing requirements [1]:

A common misconception: only churches themselves and their integrated auxiliaries are exempt. Church-run schools, charities, hospitals, and other separately incorporated organizations affiliated with churches generally must file.

The IRS enforces filing requirements through two mechanisms: financial penalties and automatic revocation of tax-exempt status. The automatic revocation rule applies equally to all four form types — even the 990-N e-Postcard [2].

Financial penalties apply to Forms 990, 990-EZ, and 990-PF (but not the 990-N). Small organizations face penalties of $20 per day for each day the return is late, up to the lesser of $10,500 or 5% of gross receipts. Large organizations — those with gross receipts exceeding approximately $1.3 million — face penalties of $130 per day, up to $65,000. These thresholds are adjusted annually for inflation [8].

Filing errors with the 990 series are common, especially among smaller organizations without dedicated finance staff. Here are the most frequent mistakes and how to avoid them.

The Form 990 series has seen several important changes in recent years, primarily around electronic filing mandates and penalty adjustments.
