IRS/Treasury Form 5558, Application for Extension of Time to File Certain Employee Plan Returns, is used by plan administrators to request an extension of the deadlines to file Forms 5500 and 8955-SSA by 2 1/2 months. The IRS and Treasury recently proposed regulations to eliminate the signature requirement to obtain a 2 1/2 month extension to file Form 5500 or Form 8955-SSA. Previously, a signature was required to obtain an extension to file Form 8955-SSA, but not for Form 5500. These proposed regulations may be relied upon immediately for forms filed on or after June 21, 2012.
