If you filed Form 4868 to request a six-month extension to file your tax return, beware that October 15, 2010 is the fast-approaching deadline to file your tax returns. The IRS expects to receive as many as ten million tax returns from such extension filers.
The other important group of filers are small nonprofit organizations at risk of losing their tax-exempt status because they failed to file the required tax returns for the past three tax years (2007, 2008, and 2009). Their one-time chance to preserve their tax-exempt status is to file the appropriate variation of the Form 990 with the IRS.
The IRS has posted on a special page on its website listing the names and last-known addresses of these at-risk organizations, along with guidance about how to come back into compliance. The organizations on the list have return due dates between May 17, 2010 and October 15, 2010, but the IRS has no record that they filed the required returns for any of the past three years.
