IRS Form 8868 Due Date: How the 6-Month Extension Works

September 15, 2024 · Last reviewed October 22, 2026 · 3 min read

Form 8868 gives a tax-exempt organization more time to file its annual return. The rules are short, but the dates trip people up. This post covers when Form 8868 is due, what the extension does, and what it does not do.

What Form 8868 does

Form 8868 is the application for an automatic extension of time to file an exempt organization return. If you complete it properly, file it on time, and pay any balance due shown on Part II, line 3c, the IRS grants an automatic 6-month extension. You do not need to give a reason.

For small nonprofits, Form 8868 is most often used to extend Form 990-EZ or Form 990. The IRS also accepts it for other returns, such as Forms 990-PF, 1041-A, 5227 and 5330.

Three limits matter:

One extension only. A single 6-month extension is allowed for each type of return for a tax year. There is no second extension.
No extension for Form 990-N. The instructions say you cannot use Form 8868 to extend the due date of Form 990-N. The e-Postcard has no extension at all, but there is also no IRS penalty for filing it late.
No extension to pay. Form 8868 does not extend the time to pay tax. If you owe tax, pay it by the original due date.

When Form 8868 is due

File Form 8868 by the due date of the return you are extending. For Form 990 and 990-EZ, that is the 15th day of the 5th month after your tax year ends. If that day falls on a Saturday, Sunday or legal holiday, the due date moves to the next business day.

The extended due date is six months later.

Calendar-year organizations

Tax year 2025 (ended December 31, 2025): the return and Form 8868 were due May 15, 2026. With an extension, the return is due November 15, 2026. That is a Sunday, so the extended deadline is Monday, November 16, 2026.
Tax year 2026 (ending December 31, 2026): May 15, 2027 is a Saturday, so the return and Form 8868 are due Monday, May 17, 2027.

Fiscal-year organizations

Many PTAs and school groups use a July 1 to June 30 year.

Year ended June 30, 2026: the return and Form 8868 are due November 15, 2026, which is a Sunday, so Monday, November 16, 2026. With an extension, the return is due May 15, 2027, which is a Saturday, so Monday, May 17, 2027.
Year ended September 30, 2026: the return is due February 15, 2027. That is Presidents' Day, a federal holiday, so the deadline is Tuesday, February 16, 2027.

If your organization uses a different year end, count to the 15th day of the 5th month after it ends, then check for a weekend or holiday.

How to file Form 8868

You can e-file Form 8868 or mail a paper form. The instructions confirm that electronic filing can be used to request an extension for each of the returns listed in Part I.

990.tax is an IRS-authorized e-file provider. It e-files Form 8868 to extend Form 990 or Form 990-EZ, for $9.99. You fill in the form, sign the e-file authorization, pay, and then 990.tax transmits it. You get an email from [email protected] when the IRS accepts or rejects it. See the step-by-step guide to e-filing Form 8868.

File early enough to correct and resend a rejected Form 8868 before the deadline.

After the extension

Use the extra time to finish your books and file the return by the extended date. 990.tax files Form 990-EZ ($89.99). It does not file the full Form 990 or Form 990-PF.

If you file after the extended due date, late-filing penalties can apply. For Form 990-EZ, the 2025 instructions list $25 a day, up to the lesser of $13,000 or 5% of gross receipts, unless you show reasonable cause.

California

California has its own extension rules. The Franchise Tax Board grants an automatic 6-month extension for Form 199 if your organization is not suspended on the original due date and you file by the extended date. You do not file a separate request. FTB 199N, the California e-Postcard, has no extension.
