Almost every organization that holds federal tax-exempt status under Section 501(a) of the Internal Revenue Code must file some version of Form 990 each year.1Office of the Law Revision Counsel. 26 USC 6033 – Returns by Exempt Organizations The specific version depends on your organization’s gross receipts and total assets, and the range runs from a short electronic notice for the smallest groups to the full Form 990 for larger ones. Churches and certain government entities are the main exceptions. For everyone else, three consecutive missed filings costs you your exempt status automatically.2Internal Revenue Service. Automatic Revocation of Exemption
Which Organizations Are Covered
If your organization is exempt under any subsection of 501(c), you almost certainly have an annual filing obligation. The rule reaches a wide range of entities:
- 501(c)(3) charities organized for religious, educational, charitable, or scientific purposes3Office of the Law Revision Counsel. 26 USC 501 – Exemption From Tax on Corporations, Certain Trusts, Etc.
- 501(c)(4) social welfare organizations
- 501(c)(5) labor, agricultural, and horticultural organizations
- 501(c)(6) business leagues, trade associations, and chambers of commerce
- 501(c)(7) social clubs, 501(c)(8) and (10) fraternal organizations, and 501(c)(19) veterans’ groups
The list is not exhaustive. The default rule is straightforward: if you were granted exempt status under 501(a), you file unless you fall into one of the specific exceptions below.4Internal Revenue Service. Annual Exempt Organization Return – Who Must File
A central organization holding a group exemption letter can file a single group return on behalf of its subordinates, which relieves each subordinate from filing separately. The group needs at least five subordinates to obtain the exemption and at least one to keep it, and every subordinate must sit under the same 501(c) paragraph and share the same accounting period.5Internal Revenue Service. Group Exemption Rulings and Group Returns
Picking the Right Version by Financial Size
The IRS looks at two numbers: annual gross receipts and total assets at the end of your tax year. Those numbers place you into one of four returns.
Form 990-N (the e-Postcard)
Organizations with gross receipts normally $50,000 or less can file the electronic notice known as the e-Postcard.6Internal Revenue Service. Annual Electronic Notice (Form 990-N) for Small Organizations FAQs – Who Must File This is not really a return. You supply your legal name, mailing address, EIN, the name and address of a principal officer, a website URL if you have one, and confirmation that gross receipts remain at or below the threshold. It takes a few minutes online.
Form 990-EZ
If gross receipts are under $200,000 and total assets are under $500,000, you can file the short-form return. Form 990-EZ asks for a statement of revenue and expenses, a balance sheet, and information about officers and directors.7Internal Revenue Service. 2025 Instructions for Form 990-EZ Many mid-sized nonprofits land here.
Form 990 (the full return)
Once your organization reaches $200,000 or more in gross receipts, or $500,000 or more in total assets, the full Form 990 is required.7Internal Revenue Service. 2025 Instructions for Form 990-EZ Either threshold triggers it, not both. Asset growth alone can push a group into the full form even when receipts are flat, which sometimes catches organizations off guard. The full return runs over a dozen pages and requires disclosure of executive compensation, governance practices, program accomplishments, and a functional breakdown of expenses.
Form 990-PF (private foundations)
Private foundations do not file Form 990 at all. They file Form 990-PF every year, regardless of receipts or assets. Even a dormant foundation with zero revenue must file to keep its exempt status.8Internal Revenue Service. 2025 Instructions for Form 990-PF – Section: Who Must File The form tracks investment income, calculates the excise tax under Section 4940, and reports grants and charitable distributions. It also verifies compliance with the Section 4942 minimum distribution rule, which requires foundations to pay out at least 5% of the fair market value of investment assets each year. A shortfall triggers a 30% excise tax on the undistributed amount, rising to 100% if the money still isn’t distributed by the end of the correction period.9Office of the Law Revision Counsel. 26 USC 4942 – Taxes on Failure to Distribute Income
Organizations That Don’t Have to File
The Code carves out specific exceptions. Knowing where you sit matters both ways: filing unnecessarily wastes effort, and assuming you’re exempt when you aren’t risks revocation.
Churches are the largest exempt category. Churches, their integrated auxiliaries, and conventions or associations of churches have no Form 990 obligation at any size.1Office of the Law Revision Counsel. 26 USC 6033 – Returns by Exempt Organizations Religious orders whose activities are exclusively religious are covered too. So are church-affiliated schools below the college level and mission societies that carry out more than half their work in foreign countries.4Internal Revenue Service. Annual Exempt Organization Return – Who Must File
Government entities and their affiliates also fall outside the requirement. State institutions with income excluded under Section 115, governmental units meeting the criteria in Revenue Procedure 95-48, and corporations organized under an Act of Congress that operate as instrumentalities of the United States all bypass Form 990.10Internal Revenue Service. Instructions for Form 990 Return of Organization Exempt From Income Tax (2025) – Section: Organizations Not Required To File Form 990 or 990-EZ
A few other groups file something else instead. Employee benefit trusts qualifying under Section 401(a) file Form 5500. Religious or apostolic organizations under Section 501(d) file Form 1065 as partnership returns. And organizations other than private foundations with gross receipts normally not more than $5,000 that have never applied for recognition of exemption are technically outside the requirement, though the IRS encourages them to file the e-Postcard anyway.4Internal Revenue Service. Annual Exempt Organization Return – Who Must File
Even organizations that don’t file should keep financial records. If the IRS questions your exempt status later, you’ll need documentation to show you still qualify.
Political Organizations Under Section 527
Political action committees, campaign funds, and other Section 527 organizations follow different thresholds. A 527 organization with gross receipts of $25,000 or more must file Form 990 or 990-EZ. A higher threshold of $100,000 applies to qualified state or local political organizations whose activities focus exclusively on state or local elections and that already file public reports with a state agency. Political committees already reporting to the Federal Election Commission, and state or local party committees, are generally not required to file Form 990.11Internal Revenue Service. Annual Information Returns – Section 527 Political Organizations
When Unrelated Business Income Adds Form 990-T
Being tax-exempt does not exempt every dollar you take in. Income from a regularly conducted business activity unrelated to your exempt purpose is taxable, and once that unrelated business income reaches $1,000 or more in gross receipts, you must file Form 990-T in addition to your regular return.12Internal Revenue Service. Instructions for Form 990-T (2025) Common triggers include advertising revenue in a nonprofit magazine, rental income from debt-financed property, and merchandise sales unrelated to your mission. Form 990-T is where you calculate and pay the tax on that income. Filing it does not endanger your exempt status. Not filing it can.
What Happens If You Don’t File
The IRS applies daily penalties for late, incomplete, or missing returns, and the amounts scale with organization size.
For Form 990 and 990-EZ, an organization with gross receipts under $1,208,500 that files late without reasonable cause pays $20 per day, capped at $12,000 or 5% of gross receipts, whichever is less. Larger organizations above that threshold pay $120 per day with a $60,000 cap.13Internal Revenue Service. Exempt Organizations Annual Reporting Requirements – Filing Procedures – Late Filing of Annual Returns If the IRS sends a written demand and the return still doesn’t come in, individual officers, directors, or trustees responsible for the failure can be personally penalized $10 per day, up to $5,000.14Internal Revenue Service. Annual Exempt Organization Return – Penalties for Failure to File
Private foundations face steeper daily rates. The Form 990-PF penalty is $25 per day for foundations with gross receipts under $1,309,500, capped at $13,000 or 5% of gross receipts. Foundations above that threshold pay $130 per day, up to $65,000. The responsible-person penalty runs $10 per day, up to $6,500.15Internal Revenue Service. 2025 Instructions for Form 990-PF – Section: Penalty for Failure To File Timely, Completely, or Correctly
Automatic Revocation After Three Missed Years
Penalties are the short-term cost. The long-term cost is worse. Any exempt organization that fails to file its required annual return or notice for three consecutive years automatically loses its tax-exempt status. This happens by operation of law, so there is no warning letter and no appeal of the revocation itself.16Internal Revenue Service. Automatic Revocation of Exemption for Non-Filing – Frequently Asked Questions The revocation takes effect on the filing due date of the third missed return.2Internal Revenue Service. Automatic Revocation of Exemption
Once revoked, the organization is treated as a taxable entity. Donations are no longer tax-deductible for donors if the group was a 501(c)(3), and any income becomes subject to regular income tax. The IRS publishes a searchable list of revoked organizations, so donors, grantmakers, and the public can see it.
Getting back on the exempt roster requires filing a new application (Form 1023 or 1023-EZ for 501(c)(3) organizations, or Form 1024 or 1024-A for other types) and paying the applicable user fee. Retroactive reinstatement can be requested as part of the application, but approval isn’t guaranteed.17Internal Revenue Service. Automatic Exemption Revocation for Nonfiling – Reinstating Tax-Exempt Status This is where organizations often discover that skipping a few e-Postcards to save a few minutes created a far more expensive problem to fix.
