The organizations listed are identified in IR 2010-87 as requiring action to retain their tax exempt status. The IRS warns, however, that the list may be incomplete, and that certain organizations may be at risk even though their names don't appear. In addition, the list may include organizations that were required to file Form 990 or Form 990-PF and so aren't eligible for the relief program, as well as organizations whose filing dates have not yet occurred. The IRS advises that donors who contribute to at-risk organizations are protected until this final revocation list is published.
