Do all 501(c)(3) nonprofits have to file a Form 990? Almost all of them, yes. Federal law requires every organization recognized as tax-exempt under Section 501(a) to file an annual information return, and 501(c)(3)s must include details about their activities and governance in that return.1Office of the Law Revision Counsel. 26 USC 6033 – Returns by Exempt Organizations The exemptions from that requirement are narrow: churches and their affiliated bodies, and certain government-affiliated entities. Everyone else files something, and the specific form depends on how much money the organization brings in.
Who Is Excused From Filing Entirely
The IRS lists the exempt categories explicitly, and they are limited.2Internal Revenue Service. Annual Exempt Organization Return: Who Must File
Religious organizations get the broadest pass. Churches, interchurch organizations of local church units, conventions or associations of churches, integrated auxiliaries of churches, and exclusively religious activities of religious orders are all exempt from filing any version of Form 990.3Internal Revenue Service. Filing Requirements for Churches and Religious Organizations There is no revenue threshold. A megachurch bringing in tens of millions of dollars annually has no federal 990 obligation, the same as a small rural congregation.
Government-affiliated entities are the other exempt group. A governmental unit or affiliate that meets the requirements in Revenue Procedure 95-48 does not need to file.2Internal Revenue Service. Annual Exempt Organization Return: Who Must File
If your organization does not fall cleanly into one of those categories, assume you have to file. The consequences of guessing wrong are severe, and there is no general small-charity exemption from the filing rule itself. Even organizations with almost no money must file the shortest version.
Which 990 You File Depends on Your Size
There are four versions of the annual return. Your gross receipts and total assets determine which one you use.
Form 990-N (e-Postcard). Available to organizations whose gross receipts are normally $50,000 or less. It is the simplest option and asks for only eight pieces of basic information: your EIN, legal name, mailing address, principal officer, and confirmation that you meet the threshold, among other items.4Internal Revenue Service. Annual Electronic Filing Requirement for Small Exempt Organizations – Form 990-N (e-Postcard)
Form 990-EZ. For organizations with gross receipts under $200,000 and total assets under $500,000 at the end of the tax year. It asks for more financial detail than the e-Postcard, including a balance sheet and a breakdown of revenue and expenses.5Internal Revenue Service. Instructions for Form 990-EZ (2025) – Section: Who Must File
Form 990 (full return). Required for organizations with gross receipts of $200,000 or more, or total assets of $500,000 or more. The full return runs dozens of pages and adds schedules covering executive compensation, governance, program accomplishments, and conflicts of interest.
Form 990-PF. Required for all private foundations regardless of financial size. A private foundation cannot use Form 990-EZ or the e-Postcard even if it falls below their financial thresholds.
How the IRS Measures “Normally $50,000 or Less”
The word “normally” in the e-Postcard threshold matters. The IRS does not simply check whether you brought in $50,000 last year. It uses a look-back formula that depends on how long the organization has existed.6Internal Revenue Service. Annual Electronic Filing Requirement for Small Exempt Organizations – Form 990-N (e-Postcard) – Section: Who May File
- One year old or less: gross receipts are considered normally $50,000 or less if the organization received (or donors pledged) $75,000 or less during its first tax year.
- Between one and three years old: gross receipts must average $60,000 or less across the organization’s first two tax years.
- Three years old or more: gross receipts must average $50,000 or less over the immediately preceding three tax years, including the current year.
The higher thresholds for newer organizations exist so that a single large startup grant does not push a genuinely small charity into a more complex return. Once you exceed the average, you move up to Form 990-EZ or the full Form 990.
When It’s Due
Every version of Form 990 is due on the 15th day of the 5th month after your organization’s fiscal year ends.7Internal Revenue Service. Annual Exempt Organization Return: Due Date For calendar-year nonprofits, that is May 15. If the date falls on a weekend or federal holiday, it shifts to the next business day.
You can file Form 8868 for an automatic six-month extension, which pushes the deadline to the 15th day of the 11th month after the fiscal year ends (November 15 for calendar-year filers).7Internal Revenue Service. Annual Exempt Organization Return: Due Date No explanation is required, but the extension has to be filed before the original deadline passes.
One exception: the Form 990-N e-Postcard cannot be extended. The IRS does not charge a penalty for a late e-Postcard on its own, but a late filing still counts toward the three-year clock that triggers automatic revocation.7Internal Revenue Service. Annual Exempt Organization Return: Due Date
All returns must be filed electronically. Since the Taxpayer First Act took effect for tax years beginning after July 1, 2019, every Form 990, 990-EZ, 990-PF, and 990-T must be e-filed.8Internal Revenue Service. E-File for Charities and Nonprofits Paper filing is no longer accepted. The 990-N was always electronic-only.
What Happens if You Don’t File
Filing late or filing an incomplete return carries the same penalty. For organizations with gross receipts under $1,208,500, the IRS charges $20 per day, up to the lesser of $12,000 or 5 percent of gross receipts. For organizations above $1,208,500 in gross receipts, the daily penalty is $120, capped at $60,000.9Internal Revenue Service. Exempt Organizations Annual Reporting Requirements – Filing Procedures: Late Filing of Annual Returns
Individuals can be penalized too. If the IRS gives the organization a deadline to provide correct information and it misses that deadline, the person responsible inside the organization can face a personal penalty of $10 per day, up to $5,000.10Internal Revenue Service. Annual Exempt Organization Return: Penalties for Failure to File Using a paid preparer does not shield the organization or its officers.
The worst outcome is automatic revocation. If your organization fails to file a required return or notice for three consecutive years, the IRS revokes your tax-exempt status by operation of law. Revocation takes effect on the original due date of the third missed return. There is no warning letter, no discretion, and no appeal. Once revoked, the organization must begin filing Form 1120 (corporation) or Form 1041 (trust) and pay income tax on its revenue, and donations to it stop being tax-deductible.11Internal Revenue Service. Automatic Revocation of Exemption
Getting Reinstated
Reinstatement requires filing a new exemption application (Form 1023 or Form 1023-EZ) and paying the user fee: $600 for Form 1023 or $275 for Form 1023-EZ.12Internal Revenue Service. Form 1023 and 1023-EZ: Amount of User Fee Even organizations that were not originally required to file an application must go through this process.13Internal Revenue Service. Automatic Revocation of Exemption for Non-Filing: Frequently Asked Questions
Whether you can be reinstated retroactively to the date of revocation depends on how quickly you act and why you failed to file. Revenue Procedure 2014-11 lays out three paths:14Internal Revenue Service. Automatic Revocation – How to Have Your Tax-Exempt Status Reinstated
- Streamlined retroactive reinstatement: for organizations that were eligible to file Form 990-EZ or 990-N for each of the three missed years, have never been auto-revoked before, and apply within 15 months of their revocation letter or of appearing on the IRS revocation list. No reasonable-cause showing required.
- Retroactive reinstatement within 15 months: for organizations that had to file the full Form 990 or 990-PF, or that have been revoked before. You must show reasonable cause for at least one of the three missed years, file all overdue returns, and apply within 15 months.
- Retroactive reinstatement after 15 months: same requirements, but you must show reasonable cause for all three missed years.
Without reasonable cause, or without seeking retroactive reinstatement, the IRS will reinstate exempt status only from the postmark date of the new application going forward. Everything in between is a gap during which the organization owed income tax and donations were not deductible.
One More Filing to Watch: Unrelated Business Income
Form 990 covers your exempt activities. It does not cover income from a business unrelated to your charitable mission. Any 501(c)(3) with $1,000 or more in gross income from an unrelated business must also file Form 990-T and pay unrelated business income tax on the profits.15Internal Revenue Service. Unrelated Business Income Tax
Income counts as unrelated business income when it meets three tests: it qualifies as a trade or business, it is regularly carried on, and it is not substantially related to the organization’s exempt purpose.16Internal Revenue Service. Unrelated Business Income Defined A museum gift shop selling educational books tied to its exhibits is likely related income. That same museum renting its parking lot to weekday commuters probably is not.
Form 990-T follows the same deadline structure as Form 990, with the same six-month extension available.17Internal Revenue Service. Return Due Dates for Exempt Organizations – Form 990-T (Corporations) Organizations expecting to owe $500 or more in unrelated business income tax must also make quarterly estimated tax payments.15Internal Revenue Service. Unrelated Business Income Tax Form 990-T must be filed electronically as well.
