Nonprofit Tax Return Due Dates and Filing Deadlines

A nonprofit’s annual federal tax return is due on the 15th day of the fifth month after its tax year ends. For nonprofits on a calendar year, the nonprofit tax return due date is May 15.1Internal Revenue Service. Annual Exempt Organization Return: Due Date Organizations with a different fiscal year apply the same five-month rule to whatever date their year closes. If the deadline lands on a Saturday, Sunday, or federal holiday, it moves to the next business day.2Office of the Law Revision Counsel. 26 USC 7503 – Time for Performance of Acts Where Last Day Falls on Saturday, Sunday, or Legal Holiday

The same date governs every version of the Form 990 series: Form 990, 990-EZ, 990-N, and 990-PF for private foundations.1Internal Revenue Service. Annual Exempt Organization Return: Due Date Timeliness is measured by the postmark for mailed returns and by the electronic timestamp for e-filed returns.

Fiscal Year Deadlines

Count five months from the close of your tax year and file by the 15th of that month.3eCFR. 26 CFR 1.6033-2 – Returns by Exempt Organizations and Returns by Certain Nonexempt Organizations A nonprofit with a fiscal year ending June 30 files by November 15. One ending September 30 files by February 15. One ending March 31 files by August 15.

Getting an Automatic Six-Month Extension

If your organization needs more time, file Form 8868 before the original deadline and you get an automatic six-month extension.4Internal Revenue Service. Instructions for Form 8868 You don’t have to explain why. A calendar-year nonprofit originally due May 15 moves its filing deadline to November 15.

Miss the window to submit Form 8868 and you lose the extension entirely. There is no second extension and no additional time beyond the six months. If your organization owes any excise taxes tied to employee benefit plans, those payments are still due by the original date regardless of the extension.5Internal Revenue Service. Form 8868 – Application for Extension of Time to File an Exempt Organization Return

Penalties for Filing Late

The IRS charges a daily penalty for any Form 990 series return filed after the deadline, including any extension. The amount depends on the organization’s size:

These figures are adjusted annually for inflation, so verify the amounts for your filing year on the IRS website.7Office of the Law Revision Counsel. 26 USC 6652 – Failure to File Certain Information Returns, Registration Statements, Etc. The same penalty applies to a return filed on time that is incomplete or incorrect.

Officers and managers can face personal liability. If the IRS sends a written demand to file and the organization still fails to comply, the responsible person owes $10 per day until the return is submitted, up to $5,000, out of that individual’s own pocket.7Office of the Law Revision Counsel. 26 USC 6652 – Failure to File Certain Information Returns, Registration Statements, Etc.

Requesting Penalty Relief

An organization that received a penalty notice can request relief by showing reasonable cause. The IRS reviews these requests individually, looking at whether the organization exercised ordinary care but still couldn’t meet the deadline. Fires, natural disasters, the death or serious illness of a key person, and system outages that blocked electronic filing all qualify.8Internal Revenue Service. Penalty Relief for Reasonable Cause

What generally will not qualify: not knowing the deadline, making a mistake, or simply running behind. Relying on a tax professional who dropped the ball usually doesn’t help either, because the IRS holds the organization responsible for its own compliance. Request relief by calling the number on the penalty notice, or by filing Form 843 if the phone request is denied.8Internal Revenue Service. Penalty Relief for Reasonable Cause

What Happens After Three Years of Missed Filings

This is where the real damage happens. A tax-exempt organization that fails to file its required annual return or notice for three consecutive years has its exempt status automatically revoked by the IRS. There is no warning letter and no grace period. Revocation takes effect on the filing due date of that third missed year.9Internal Revenue Service. Automatic Revocation of Exemption for Non-Filing: Frequently Asked Questions Every type of exempt organization with a filing obligation is subject to this rule, including organizations small enough to file only the 990-N e-Postcard.

Once revoked, donations to the organization are no longer tax-deductible, and the organization itself may owe income tax on its revenue. The IRS publishes a searchable list of automatically revoked organizations online.10Internal Revenue Service. Copies of EO Returns Available Small, volunteer-run nonprofits often assume the e-Postcard is optional because it’s so short. It isn’t.

Reinstatement

A revoked organization can apply for reinstatement, but the process means reapplying from scratch on the same forms a brand-new organization would submit: Form 1023 or 1023-EZ for 501(c)(3) charities, or Form 1024 or 1024-A for other types. Each carries a user fee.11Internal Revenue Service. Automatic Revocation – How to Have Your Tax-Exempt Status Reinstated

To have reinstatement apply retroactively to the date of revocation, and avoid a gap where the organization was technically taxable, you generally need to apply within 15 months of the revocation letter or the date your organization appeared on the IRS revocation list, whichever is later. You’ll also need to file all the missed returns and, for organizations that don’t qualify for the streamlined process, provide a written reasonable-cause statement.11Internal Revenue Service. Automatic Revocation – How to Have Your Tax-Exempt Status Reinstated

Which Form 990 Your Organization Files

The deadline is the same across the series, but filing the wrong version can trigger processing delays or requests for more information. The version you use depends on size:

An organization eligible for a simpler form can always choose to file a more detailed one. A small charity that qualifies for the 990-N could file a full Form 990 if it wants the transparency of a complete financial disclosure.12Internal Revenue Service. Annual Electronic Filing Requirement for Small Exempt Organizations – Form 990-N (e-Postcard)

Organizations Without a Filing Requirement

Not every tax-exempt organization owes an annual return. Churches, their integrated auxiliaries, and conventions or associations of churches are exempt from the Form 990 filing requirement under federal law.14Office of the Law Revision Counsel. 26 USC 6033 – Returns by Exempt Organizations Certain government entities and organizations included in a parent organization’s group return also fall outside the individual filing obligation.15Internal Revenue Service. Exempt Organizations Annual Reporting Requirements – Overview – Returns by Members of Group Ruling

A central parent organization can file a single group return covering some or all of its subordinates, but each subordinate must agree to be included. Any subordinate not covered in the group return must file its own.15Internal Revenue Service. Exempt Organizations Annual Reporting Requirements – Overview – Returns by Members of Group Ruling

State Deadlines Are Separate

Federal filing is only part of the picture. Roughly 40 states require charitable organizations to register before soliciting donations from residents, and most require annual renewals with their own deadlines and fees.16Internal Revenue Service. Charitable Solicitation – Initial State Registration Some states tie their deadline to the federal return date; others set their own calendar entirely. Annual registration fees range from under $10 to over $1,000 depending on the jurisdiction and the organization’s revenue. Check with your state attorney general’s office or secretary of state for the requirements that apply to your organization.
