Form 990 is due on the 15th day of the 5th month after your organization’s tax year ends. For a nonprofit that runs on the calendar year, that means May 15. If you need more time, Form 8868 buys an automatic six-month extension, but you have to file it by the original due date. Miss the deadline entirely and daily penalties start running; miss it three years in a row and the IRS revokes your tax-exempt status automatically.
Figuring Out Your Exact Due Date
Take the last day of your organization’s tax year and count forward five months. The return is due on the 15th of that fifth month.1Internal Revenue Service. Annual Exempt Organization Return: Due Date
Most nonprofits use a calendar year ending December 31, which puts the deadline on May 15. If your fiscal year ends June 30, your deadline is November 15. A fiscal year ending September 30 produces a February 15 deadline, and so on. If the 15th falls on a Saturday, Sunday, or federal holiday, the due date shifts to the next business day.
The same deadline applies whether you file Form 990, 990-EZ, 990-PF, or the 990-N e-Postcard. The version you owe depends on your size, but the timing does not change.
Getting a Six-Month Extension
If you cannot make the original date, file Form 8868 for an automatic six-month extension.2Internal Revenue Service. Instructions for Form 8868 A calendar-year organization that submits Form 8868 by May 15 gets a new deadline of November 15. A June 30 year-end that extends from November 15 lands on May 15 of the following year.
The extension is automatic, but only if you submit it on time. Filing 8868 after the original due date does nothing for you. The form asks for the organization’s legal name, mailing address, EIN, the type of return you plan to file, the tax year, and an estimate of any tax owed. Most organizations filing an information return report zero tax, but the field still has to be completed.
One thing worth knowing: the six months is the full extension available. There is no second extension after that.
What Happens If You File Late
Missing the deadline triggers daily penalties under 26 U.S.C. ยง 6652, adjusted each year for inflation. For returns required to be filed in 2026:
- Organizations with gross receipts of $1,309,500 or less owe $25 per day the return is late, capped at the lesser of $13,000 or 5 percent of the year’s gross receipts.3Office of the Law Revision Counsel. 26 USC 6652 – Failure to File Certain Information Returns, Registration Statements, Etc
- Organizations with gross receipts above $1,309,500 owe $130 per day, capped at $65,000.
The penalty adds up fast. A mid-size nonprofit that is roughly two months late can hit the full $13,000 cap.
One more thing to watch: every 990 return has to be filed electronically. A paper return from an organization required to e-file is treated as if nothing was filed at all, so the daily penalty keeps running even though you sent something in.4Internal Revenue Service. Instructions for Form 990 Return of Organization Exempt From Income Tax
Personal Liability for Officers
If the IRS sends a written demand for a delinquent return and the organization still does not file, the individuals responsible, usually officers, directors, or trustees, face a separate personal penalty of $10 per day, up to $6,500 per return. Reasonable cause is a defense, but the individual has to prove it.
Three Years of Non-Filing Costs You Your Exempt Status
The worst-case outcome is not the daily fine. If your organization fails to file a required return or notice for three consecutive years, the IRS automatically revokes tax-exempt status. Revocation takes effect on the original due date of the third missed return.5Internal Revenue Service. Automatic Revocation of Exemption This rule applies to every version of the return, including the 990-N e-Postcard, which some very small organizations wrongly treat as optional.
Once revoked, the organization owes federal income tax on its earnings and can no longer receive tax-deductible contributions. The IRS publishes a searchable list of revoked organizations, so donors and grantmakers see the change quickly.6Internal Revenue Service. Automatic Revocation of Exemption for Non-Filing: Frequently Asked Questions Reinstatement is possible under Revenue Procedure 2014-11, but the process involves a new application, a user fee, and often filing every delinquent return on paper. Filing on time, or filing an extension, is much simpler than climbing back out.
Asking the IRS to Waive a Late Penalty
If your organization has already been hit with a late-filing penalty, two paths lead to relief.7Internal Revenue Service. Penalty Relief for Reasonable Cause
The first is First Time Abate. The IRS may grant it if your organization filed on time and paid what was owed for the three prior tax years. The compliance history does the work; you do not have to explain what went wrong.
The second is reasonable cause relief, which requires showing your organization used ordinary care but still could not file on time. The IRS considers each request on its own facts. Situations that generally qualify include fires or natural disasters, inability to access records, death or serious illness of a key person, and system failures that blocked timely e-filing. Situations that generally do not qualify include reliance on a tax preparer, not knowing about the filing requirement, simple mistakes, and lack of funds by itself.
To ask for relief, call the number on your penalty notice, send a written statement, or submit Form 843 (Claim for Refund and Request for Abatement). If you request reasonable cause but qualify for First Time Abate instead, the IRS will apply that automatically and let you know.8Internal Revenue Service. Administrative Penalty Relief
Two dates matter most for staying out of this territory: your original due date, and the extended date if you filed Form 8868. Put both on the calendar the moment your tax year closes.
