This guide is a summary and isn't tax advice. For the current requirements, check the IRS return due dates page. The IRS can change thresholds, dates and penalty amounts at any time.

How the deadline works

Start from the last day of your organization's tax year and count forward to the 15th day of the 5th month. For a tax year ending December 31, that's May 15. If that day is a Saturday, Sunday or legal holiday, the return is due the next business day.

Form 8868 generally gives you six more months to file Forms 990, 990-EZ and 990-PF, to the 15th day of the 11th month, with the same weekend and holiday rule. You must file it by the original due date, and it doesn't extend the time to pay tax. Form 990-N can't be extended.

The IRS can postpone deadlines for organizations affected by a federally declared disaster or similar event. They announce those postponements separately, and this table doesn't include them. If one may apply to you, check the IRS's current announcements.

Missing the deadline

If you file after the due date, including any extension, the IRS can charge a daily penalty unless your organization shows reasonable cause. Three consecutive years without a required return or notice ends tax-exempt status. The late filing guide has the amounts and the IRS source.

Questions

When is Form 990 due?

Forms 990, 990-EZ, 990-N and 990-PF are due on the 15th day of the 5th month after the tax year ends. For a tax year ending in December, that's May 15. If May 15 falls on a weekend or legal holiday, the deadline moves to the next business day.

What if the Form 990 deadline falls on a weekend?

If the regular filing deadline falls on a Saturday, Sunday or legal holiday, it moves to the next business day. Count to the 15th day of the 5th month after your tax year ends, then check the calendar.

Can I get an extension for Form 990?

Yes. Filed on time, Form 8868 generally gives an automatic six-month extension of time to file Forms 990, 990-EZ and 990-PF. It doesn't extend the time to pay tax. The deadlines table shows the extended date for each year-end month. Form 990-N can't be extended, but it has no monetary penalty for filing late.

When is Form 990-PF due?

A private foundation's Form 990-PF is due on the 15th day of the 5th month after its tax year ends, like the other annual returns. For a calendar tax year 2025, that's Friday, May 15, 2026, or Monday, November 16, 2026 with Form 8868.

When is Form 990-EZ due?

Form 990-EZ has the same due date as Form 990: the 15th day of the 5th month after the tax year ends. For a calendar tax year 2025, that's Friday, May 15, 2026, or Monday, November 16, 2026 with Form 8868.

When is Form 990-N due?

Form 990-N is due on the 15th day of the 5th month after the tax year ends: Friday, May 15, 2026 for a calendar tax year 2025. It can't be extended, because Form 8868 doesn't apply to Form 990-N.

Can I get a second extension?

No. The IRS allows a single six-month extension for each return for a tax year. A calendar tax year 2025 return extended with Form 8868 is due Monday, November 16, 2026, and it can't be extended again.
