This document contains final and temporary regulations relating to the simplification of procedures for obtaining automatic extensions of time to file certain returns. The portions of this document that are final regulations provide necessary cross-references to the temporary regulations. The temporary regulations allow individual income taxpayers and certain other taxpayers to obtain an automatic six-month extension of time to file certain returns by filing a single request. For these returns, the temporary regulations also remove the requirements for a signature and an explanation of the need for an extension of time to file. The temporary regulations affect taxpayers who are required to file certain returns and need an extension of time to file. The text of the temporary regulations also serves as the text of the proposed regulations set forth in the notice of proposed rulemaking on this subject in the Proposed Rules section of this issue of the Federal Register.
