The 990 tax form for nonprofits is an annual informational return that tax-exempt organizations file with the IRS to report how they earn and spend money, who leads them, and whether they still operate in line with the charitable purpose that earned them exempt status. Nearly every organization recognized as tax-exempt under Section 501(a) of the Internal Revenue Code must file some version of it each year.1Internal Revenue Service. Annual Exempt Organization Return: Who Must File Unlike a standard tax return, it usually calculates no tax; it documents your activities for the IRS and for the public, since the completed return is a public record.
Which Version Your Organization Files
The IRS publishes four variants, and the one you use depends on your gross receipts and total assets.
- Form 990-N, often called the e-Postcard, is for organizations whose gross receipts are normally $50,000 or less. It asks for little more than your name, address, and taxpayer identification number.2Internal Revenue Service.

- Form 990-EZ is available to organizations with gross receipts under $200,000 and total assets under $500,000.3Internal Revenue Service. Instructions for Form 990 Return of Organization Exempt From Income Tax
- The full Form 990 applies once gross receipts reach $200,000 or total assets reach $500,000.3Internal Revenue Service. Instructions for Form 990 Return of Organization Exempt From Income Tax
- Form 990-PF is filed by private foundations regardless of size and includes excise tax calculations on investment income and a check on required annual distributions.4Internal Revenue Service. Annual Electronic Notice (Form 990-N) for Small Organizations FAQs: Who Must File
Every version in the 990 series must be filed electronically. The Taxpayer First Act made e-filing mandatory for Form 990, 990-EZ, 990-PF, and 990-T, and paper filing is no longer accepted.5Internal Revenue Service. E-file for Charities and Nonprofits
Who Does Not Have to File
Churches, synagogues, mosques, and similar houses of worship are permanently exempt from filing a 990, no matter how much revenue they bring in. The exemption also covers church-affiliated auxiliaries, conventions of churches, and the exclusively religious activities of religious orders.6Internal Revenue Service. Filing Requirements for Churches and Religious Organizations Government entities performing governmental functions are also outside the filing requirement. Everyone else with a 501(a) determination letter needs to file something.
When the Return Is Due
Form 990, 990-EZ, and 990-PF are due on the 15th day of the 5th month after your organization’s fiscal year ends. For a calendar-year filer, that is May 15. Form 8868 gives you an automatic six-month extension without any explanation, which pushes a calendar-year deadline to November 15.7Internal Revenue Service. Annual Exempt Organization Return: Due Date An extension to file is not an extension to pay. If your organization owes tax, such as unrelated business income tax on Form 990-T, payment is still due by the original date.
What the Form Reports
The full Form 990 opens with your mission statement and a summary of the year’s most significant accomplishments, including who you served and what outcomes you achieved. The point is to show concretely that you are still doing what you told the IRS you would do when you applied for tax-exempt status.
Financial Detail and Compensation
The financial sections break down revenue and expenses, and Part VII gets the most scrutiny. You must list all current officers, directors, and trustees by name, whether or not they are compensated. You also list your five highest-compensated employees earning at least $100,000 in reportable compensation from the organization and related entities, and up to 20 key employees earning more than $150,000.8Internal Revenue Service. Form 990 Part VII and Schedule J Reporting Executive Compensation Individuals Included Compensation includes salaries, bonuses, and non-taxable benefits. The form also tracks professional fundraising fees and lobbying expenditures.
If your organization had financial transactions with board members, founders, substantial contributors, or their family members, Schedule L requires you to disclose them. The IRS uses this schedule to catch self-dealing and private benefit arrangements that could put exempt status at risk.9Internal Revenue Service. Instructions for Schedule L (Form 990)
Governance Policies
Part VI asks whether you have adopted specific internal governance policies. The IRS does not legally require most of them, but the form asks anyway. The main ones are a written conflict-of-interest policy, a whistleblower protection policy, and a document retention and destruction policy. The form also asks whether you use an independent process for setting executive compensation, including board review, comparability data, and written documentation of the decision.10Internal Revenue Service. 2025 Instructions for Form 990 Return of Organization Exempt From Income Tax Answering “no” carries no automatic penalty, but the answers are public, and grantmakers read them.
Unrelated Business Income and Form 990-T
Tax-exempt status does not shield every dollar you earn. If your nonprofit runs a business activity that is regularly carried on and not substantially related to its exempt purpose, the income is taxable. Common examples include advertising revenue in a publication or on your website, rental income from debt-financed property, and commercial services that go beyond your mission.
If your organization earns $1,000 or more in gross income from unrelated business activities, you must file Form 990-T and pay tax on the net income at the 21% corporate rate. If you expect the tax to be $500 or more for the year, you also owe quarterly estimated payments.11Internal Revenue Service. Unrelated Business Income Tax Passive income such as dividends, interest, royalties, and qualified sponsorship payments is excluded even when it comes from unrelated sources.
Penalties for Late or Missing Filings
For organizations with gross receipts under $1,208,500, the IRS charges $20 per day the return is late, up to a maximum of $12,000 or 5% of gross receipts, whichever is less. Larger organizations face $120 per day, with the cap rising to $60,000.12Internal Revenue Service. Late Filing of Annual Returns These figures are adjusted for inflation periodically.13Office of the Law Revision Counsel. 26 USC 6652 – Failure to File Certain Information Returns, Registration Statements, Etc
The harsher consequence is automatic revocation. If your organization fails to file any required return or notice for three consecutive years, the IRS revokes your exemption automatically. There is no hearing and no grace period beyond a warning letter sent after two missed years.14Office of the Law Revision Counsel. 26 USC 6033 – Returns by Exempt Organizations This applies even to small groups that only owed the e-Postcard.
Getting Exempt Status Back
To recover from revocation, you must file a new application for tax-exempt recognition and pay the applicable user fee, even if you were never required to apply originally. The IRS may grant reinstatement effective from the date you submit the new application, or retroactively to the revocation date if you can show reasonable cause for the missed filings.15Internal Revenue Service. Reinstatement of Tax-Exempt Status After Automatic Revocation During the gap, donations are not tax-deductible for donors, and income may be subject to corporate income tax.
Public Disclosure of the Return
Your Form 990 is a public document. Federal law requires you to make your three most recent annual returns available for inspection during regular business hours at your principal office. If someone asks in person, you must hand over copies immediately. Written requests give you 30 days to respond.16Office of the Law Revision Counsel. 26 US Code 6104 – Publicity of Information Required From Certain Exempt Organizations and Certain Trusts
Refusal carries a penalty of $20 per day, up to $10,000 per return.17Internal Revenue Service. Public Disclosure and Availability of Exempt Organizations Returns and Applications: Penalties for Noncompliance If the failure is willful, the responsible person owes an additional $5,000 per return.18Office of the Law Revision Counsel. 26 USC 6685 – Assessable Penalty With Respect to Public Inspection Requirements Most organizations meet the requirement by posting returns on their website or through a third-party database.
Donor Names Stay Private
Donor identity is the one piece that stays private. Schedule B lists contributors who gave $5,000 or more (or met other thresholds), but you are not required to disclose contributor names or addresses to the public. The publicly available copy of your return should have that information redacted. Private foundations and 527 political organizations are the exceptions and must disclose contributor information publicly.19Internal Revenue Service. Public Disclosure and Availability of Exempt Organizations Returns and Applications: Contributors Identities Not Subject to Disclosure Accidentally including Schedule B in a public copy is a common compliance mistake, so a second set of eyes on anything you post or mail is worth the trouble.
