IRS Form 990-N is an online tax form for tax-exempt organizations with gross receipts of less than $50,000 per year, says the Internal Revenue Service. The IRS commonly refers to Form 990-N as the e-Postcard because filing organizations access, complete and submit the form electronically.
The IRS states that the annual due date for Form 990-N is five months and 15 days after the close of an organization's official tax year. There is no penalty associated with missing an annual filing due date or for failing to file at all during the course of a year. However, an organization that fails to file Form 990-N or an acceptable alternate form for three years in a row automatically loses its tax-exempt status. The two acceptable alternate forms are IRS Form 990 and IRS Form 990-EZ.
