The deadline for tax-exempt organizations to file the Form 990 or Form 990-EZ (informational returns) is May 15. Tax-exempt organizations that cannot meet the deadline may request an automatic three-month extension using Form 8868.
In 2006, for the first time, exempt organizations are required to file electronically if the organization has more than $100 million in total assets and file at least 250 total tax returns per year.
