The IRS Form 990 filing deadline for tax-exempt organizations is the 15th day of the 5th month after the end of the organization’s tax year.
For calendar-year nonprofits, Form 990 is generally due by May 15. Filing late may result in IRS penalties and could affect an organization’s tax-exempt status. Nonprofits that need additional time to file can request an automatic 6-month extension by submitting Form 8868 before the original Form 990 due date.
