The Form 990 filing deadline for most tax-exempt organizations is the 15th day of the 5th month after the close of the organization’s tax year.1Internal Revenue Service. Annual Exempt Organization Return: Due Date For a calendar-year nonprofit, that means May 15 of the following year. Miss it without an extension and daily penalties start running; miss it for three years in a row and your tax-exempt status is revoked automatically by operation of law.
When Form 990 Is Due
Take the last day of your fiscal year, move forward five months, and land on the 15th. A calendar-year organization (January 1 through December 31) files by May 15. An organization whose fiscal year ends June 30 files by November 15. An October 31 year-end produces a March 15 deadline.
When the 15th falls on a Saturday, Sunday, or federal holiday, a return filed on the next business day counts as timely. The same deadline applies to Form 990, Form 990-EZ, Form 990-N (the e-Postcard), and Form 990-PF for private foundations.2Internal Revenue Service. Form 990 Series Which Forms Do Exempt Organizations File Filing Phase In Which version you use depends on your organization’s size, but the due date does not change.
Which Form You File Does Not Change the Deadline
The e-Postcard (Form 990-N) is available to organizations with gross receipts normally at or below $50,000.3Internal Revenue Service. Annual Electronic Filing Requirement for Small Exempt Organizations – Form 990-N (e-Postcard) Form 990-EZ is for organizations with gross receipts under $200,000 and total assets under $500,000 at year-end.4Internal Revenue Service. 2025 Instructions for Form 990-EZ Organizations above those thresholds file the full Form 990, and private foundations file Form 990-PF regardless of size.5Internal Revenue Service. Private Foundation – Annual Return All four share the same 15th-day-of-the-5th-month due date.
Churches, their integrated auxiliaries, conventions or associations of churches, and the exclusively religious activities of religious orders are not required to file at all.6Office of the Law Revision Counsel. 26 USC 6033 – Returns by Exempt Organizations If your organization does not fall into one of those categories, you have a deadline.
Getting an Extension
If you need more time, file Form 8868 on or before the original due date and you get an automatic six-month extension.7Internal Revenue Service. Instructions for Form 8868 (01/2026) No reason required. The extension is granted automatically as long as the form is complete and submitted on time. A calendar-year nonprofit that files Form 8868 by May 15 has until November 15 to file its 990.
One caveat: an extension of time to file is not an extension of time to pay any tax owed on unrelated business income. If you owe tax, pay it with the extension request to avoid interest and late-payment penalties.
Disaster-Area Postponements
When FEMA declares a federal disaster, the IRS typically postpones filing and payment deadlines for affected taxpayers, including nonprofits whose principal office sits in the covered area.8Internal Revenue Service. Disaster Assistance and Emergency Relief for Individuals and Businesses These postponements apply automatically. You do not need to contact the IRS or file additional paperwork. The IRS disaster relief page lists covered locations and revised deadlines.
What Late Filing Costs
File after the deadline (including any extension) without reasonable cause and daily penalties start. The amounts are adjusted for inflation. For 2026 tax years:
- Organizations with gross receipts below $1,339,500 face a penalty of $25 per day, capped at the lesser of $13,000 or 5 percent of the organization’s gross receipts.
- Organizations with gross receipts of $1,339,500 or more face $130 per day, capped at $66,500 per return.
The IRS can also impose a separate personal penalty on any officer or manager who fails to file after receiving a written demand, at $10 per day up to $5,000.9Office of the Law Revision Counsel. 26 USC 6652 – Failure to File Certain Information Returns, Registration Statements, Etc. The penalty falls on the organization and its leadership, not on a hired preparer.
The Three-Year Rule: Automatic Revocation
The harshest consequence is not a penalty at all. If your organization fails to file a required Form 990, 990-EZ, 990-PF, or 990-N for three consecutive years, its tax-exempt status is revoked automatically by operation of law.10Internal Revenue Service. Automatic Revocation of Exemption The revocation takes effect on the due date of the third missed return. It is not a discretionary IRS decision, and the IRS publishes a list of revoked organizations on its website.11Internal Revenue Service. Automatic Revocation of Exemption for Non-Filing: Frequently Asked Questions
Once revoked, the organization becomes subject to federal income tax. Donations are no longer tax-deductible for donors. To regain exempt standing, the organization has to formally reapply and pay a user fee.
Reinstating an Exemption After Revocation
Four reinstatement paths exist, and which one is available depends on your organization’s size, filing history, and how quickly you act.12Internal Revenue Service. Automatic Revocation – How to Have Your Tax-Exempt Status Reinstated
- Streamlined retroactive reinstatement is open to organizations that were eligible to file Form 990-EZ or 990-N during the three years that caused the revocation and that have never been revoked before. Apply within 15 months of the revocation letter or the date you appeared on the IRS Revocation List, whichever is later, and exempt status is restored back to the revocation date.
- Retroactive reinstatement within 15 months is for organizations that do not qualify for the streamlined process (those required to file the full Form 990, or previously revoked). You apply within the same 15-month window, show reasonable cause for at least one of the three missed years, and file all overdue returns.
- Retroactive reinstatement after 15 months is still available but requires reasonable cause for all three missed years, a significantly higher bar.
- Post-mark date reinstatement is open to any revoked organization without a reasonable-cause showing, but exempt status only resumes from the date the application is postmarked. The period between revocation and reinstatement remains taxable.
Every path requires a new exemption application (Form 1023, 1023-EZ, 1024, or 1024-A) with the applicable user fee. Acting fast after learning of a revocation preserves the widest set of options.
A Separate Deadline If You Have Unrelated Business Income
If your organization earns $1,000 or more in gross income from a regularly conducted trade or business unrelated to its exempt purpose, it must also file Form 990-T.13Internal Revenue Service. Instructions for Form 990-T (2025) Common examples include advertising revenue in a nonprofit publication, rental income from debt-financed property, and commercial services unrelated to the mission.
For most organizations, Form 990-T shares the Form 990 deadline: the 15th day of the 5th month after the tax year ends. Certain trusts, including IRAs and Roth IRAs, face an earlier deadline of the 15th day of the 4th month. Form 990-T can produce an actual tax bill, so plan for a payment alongside the filing.
Practical Takeaway
Mark the 15th day of the 5th month after your fiscal year end. If that date is going to be tight, file Form 8868 before it arrives and take the automatic six-month extension. If you are already behind and it has been less than three years, file the missing returns and pay any resulting penalty. If it has been three years, assume revocation has already happened and move immediately to the reinstatement process that fits your situation.
