Upcoming Form 990 Filing Deadline: What Tax-Exempt Organizations Need to Know Before November 15, 2026

An important Form 990 filing deadline is quickly approaching for many tax-exempt organizations. Organizations with a June 30, 2026, fiscal year-end are required to file their annual Form 990 return by November 15, 2026, which is the 15th day of the fifth month following the end of their tax year. Organizations that need additional time to file may request an automatic six-month extension by submitting Form 8868 on or before the original due date. A timely extension extends the filing deadline to May 15, 2027.

It is also important to note that November 15, 2026, is the final extended filing deadline for organizations with a December 31, 2025,year-end that timely filed Form 8868. Calendar year-end organizations were originally required to file their Form 990 by May 15, 2026. Organizations that obtained an extension must file a completed return by November 15, 2026, as no additional extension is available.

Who Is Required to File a Form 990?

Most organizations recognized as tax-exempt under Internal Revenue Code Section 501(c) are required to file an annual information return with the IRS.

The Form 990 series includes the following filing requirements:

• Form 990-N (e-Postcard): Filed by organizations with annual gross receipts of $50,000 or less
• Form 990-EZ: Filed by organizations with annual gross receipts of less than $200,000 and total assets of less than $500,000
• Form 990: Filed by organizations with annual gross receipts of $200,000 or more or total assets of $500,000 or more
• Form 990-PF: Filed by most private foundations regardless of revenue or asset levels

Public Disclosure and Compliance

Form 990 is more than just an annual filing requirement. It gives the IRS and the public a snapshot of an organization's activities, finances, and operations. Many donors, grantors, lenders, and other stakeholders review Form990 filings to learn more about an organization's mission, programs, and overall financial health.

Timely filing is also important for maintaining tax-exempt status. Organizations that fail to file a required Form 990-series return for three consecutive years automatically lose their tax-exempt status. Reinstating that status can be time-consuming and costly, making annual compliance an important responsibility.

Extension Opportunities

Organizations that are unable to file by their original due date may request an automatic six-month extension by filing Form 8868. For organizations with a June 30, 2026, year-end, a timely extension extends the filing deadline from November 15, 2026, to May 15, 2027

Final Reminder

With the November 15, 2026, deadline approaching, organizations should review their filing requirements and determine whether they are approaching an original due date or a final extended due date. Organizations with a June 30,2026, fiscal year-end must either file their return or submit Form 8868 by November 15, 2026. Organizations with a December 31, 2025, year-end that previously obtained an extension must file their completed return by November15, 2026. Taking steps now to prepare for the filing deadline can help ensure compliance, maintain tax-exempt status, and avoid unnecessary penalties.
